How To Diagnose A Faulty Boiler Diverter Valve

A diverter valve opens and closes to provide heat to the radiators or to increase the temperature of water. These valves are also installed at your bathroom to heat your water. But if there is any fault in the valve, you may not get hot water. It usually happen when the valve is jammed or not working properly.

When you turn on the heating to get hot water through tap, but you did not get shows that the valve is jammed open in the heating mode. And if you get all hot water, but no heating, ensure all your time clocks and controls are working fine. If you find no issue with them, then this means your valve is not opening for the heating.

How to fix the fault?

When you find the fault, you should always take precaution and call expert to replace the diverter valve or repair the valve parts if possible. If you have a boiler under eight years old, this should be fixed in less than an hour since the parts are readily available.

If a combi boiler is eight years old or more, you may find it difficult to source parts.

How to decide the budget?

A combi boiler diverter valve usually cost between 100 pounds to 150 pounds, excluding the charges of labor and time. If we include the both, it will cost you around 250 pounds to get your faulty diverter valve repaired. The valve should come with parts. However, this could depend on the age of your boiler because manufacturers stop making some parts over time.

If you are on warranty plan, this would save the money. But if your boiler is older and you need replacement of parts often, it is advisable to replace the entire boiler.

When you replace the boiler, you will find that your monthly bills will be low and there will be lesser requirement for repairing the valves or other parts of boiler.

For more details on diverter valves, you may contact diverter valve manufacturer and supplier in your town. If you want to source some valves, research online and in the market. Make sure you source the premium quality valves for your application.

Selecting Diverter Valves is Tough When You Don’t Know About Reality

Deciding on right type of diverter valve may be tough especially when you have to buy them from market. Properly selected diverter valve helps you in running operations smoothly. This also cuts down maintenance costs and improves conveying system effectively. In this blog, we have outlined some of the important factors that would help you in deciding on right diverter valves.

  • Application type – Diverter valves are two way valves that help in sourcing materials from one source to another. These valves are generally installed backward to convey materials from different sources and one destination. This is the reason why they are called as two way valves. Further, converting converge valves to diverter valves may be costly and it increases overall prices of valve. So, you should always select valves carefully before making any final decision.In case, you have more than two sources then installing diverter valves is always affordable and meets system requirements well. However, installing diverter valves with more than one port are named as multi port diverter valves.
  • Conveying system type – The choice of diverter valve depends on either your pneumatic system is dilute or denser. A dilute conveying system may tolerate pressure up to 15 psig and denser conveying system may tolerate pressure up to 90 psig. So, this is up to you which system suits your requirements the most based on application requirements.When pressure is set accurately then valve will function properly and it is also easy to install them. They are further available in different sizes, so you should decide on valves carefully.
  • Material properties – Don’t forget to focus on material characteristics like particle size, dimensions or specifications etc. These factors are necessary to consider for proper selection of valve. If size or dimensions are not selected carefully then small particles may pack between internal components or it will spoil the diverter valves.

You have to understand all of these facts carefully before taking any final decision. These factors will help you in making the right decision at the right time. To know more about diverter valves, this is always better to contact leading diverter valve manufacturers India right away.

How Do Rotary Airlock Valves Work?

A rotary airlock valve, also known as a rotary feeder or rotary valve, is a commonly used component of specialty or bulk material handling systems in industrial and agricultural settings. They are mostly used in the discharge of solid material in bulk from hoppers or bins into a conveying system. These rotors are typically driven by a small internal combustion engine or an electric motor and usually have large metal vanes that are cast or welded on to it.

How Do They Work?

The rotary airlock valves serve as a lock that prevents air loss while also performing other functions of handling materials. The metal vanes or blades on a rotary airlock rotate while it is in operation, and this creates a pocket between the blades. The material that is handled by it enters these pockets via the inlet ports and exits via the outlet ports. In an airlock between the inlet port and outlet port, an airlock valve keeps some air sealed inside, allowing the material that is being handled to move downwards from the inlet port, into the valve, and then out through the outlet port. The controlled air flow helps in maintaining a constant air pressure between the ports which helps in moving the material through the ports. The maintenance of the air pressure is, therefore, essential to the functioning of a rotary airlock valve.

Uses of Rotary Airlock Valves

Rotary airlock valves are found to be quite useful in a wide range of industrial and agricultural settings where dry and free-flowing solids, granules or powders such as cement, ore, sugar, grains etc are used. Rotary airlock valves are also useful in pollution control in a variety of industries such as wood, paper, textile, tobacco and so on.

Components of a Rotary Airlock Valve

The components of a rotary airlock valve include the rotor shaft which is the axis around which the whole system rotates, housing, headplates, packing seals and bearings, each of which serve specific functions that enable the rotary feeder to perform its job. A rotary airlock valve that is typically supported by bearings will be driven by an internal combustion engine or an electric motor.

The Effects of Improper Airlocks

Rotary airlocks are an integral part of a number of conveying systems. A rotary airlock valves manufacturer India would, therefore, recommend that the airlock valves be used properly. Undue wear and tear of the rotor, the housing or both will lead to airlock failure and will drive up the cost of maintenance. When processing abrasive materials, care must be taken to reduce cumulative damage from the material particles being trapped in the vanes of the rotary airlock valves. A common cause for damage is when trapped materials produce surface drag abrasion from being stuck in between planes that are moving in two different directions. Similarly, pneumatic surface abrasions are caused by turbulent air that gets accumulated at the outlet port and this can lead to severe loss of efficiency and issues with material flow because this wayward air could carry abrasive materials with it that would cause damage to the valve.

Key Variables of its Performance

The performance of a rotary airlock valve depends on certain key variables such as the number of blades, the type of rotors and the wear and abrasion of the rotary airlock valves. The more the number of blades present, the more efficient it will be in sealing the pressure difference between the inlet port and outlet port.

Hence, it can be concluded that selecting the right kind of rotary feeder or rotary airlock valve is important to get the maximum amount of efficiency.

Rotary airlocks are used as material handling system in a bulk or in a special material. They are majorly used in the agricultural and industrial applications. Rotary airlock valves are also known as rotary feeders and rotary valves.

Types of Rotary Airlock Valves and Their Applications

A rotary airlock valve is a device that is largely used in material handling processes in industrial settings. Typically, it consists of metal vanes that are cast or welded on it to form pockets between two consecutive metal vanes. The material enters through an inlet port and exits through an outlet port onto a conveying system. Additionally, the airlock seals air between the inlet port and outlet port in order to maintain the air pressure. This air pressure is essential in carrying the material from the inlet port to the outlet port.

Types of Airlock Valves

Typically, depending on how the rotary airlock valve functions, it can be divided into the following types:

  • Angle of Repose (ARF) Rotary Airlock Valve

An angle of Repose Rotary Airlock Valve is a type of rotary feeder system that uses variable speed for the transport of bulk materials in synchronization with the natural flow of the bulk material. With the help of a rotating member and an articulable gate, the ARF can control the volume of material flow in accordance with the angle of repose.

  • Drop-through Rotary Airlock Valve

These valves are used in settings that require rugged applications where abrasive products need to be handled. They require an outboard bearing style in cases where an inboard bearing style cannot handle contamination or abrasive products.

  • Blow-thru Rotary Airlock Valve

The Blow-thru rotary feeders or airlock valves have a large capacity and low profile that makes them ideal for pneumatic conveying purposes in industries such as food, grain, plastic, baking and so on.

  • Rotary Airlock Valve Degassing

This type of rotary feeder has a small hopper that is attached to it which enables it to release the gas that gets leaked into the valves and through the cracks between the valves and the walls. This gas can prevent the undisrupted flow of material into the valve and so, the hopper enables it to improve its efficiency.

  • Easy Clean Rotary Valve

The easy clean rotary airlock valve can be swiftly disassembled and reassembled, enabling it to be cleaned easily. This increases efficiency and reduces the downtime that goes in towards its maintenance.

  • Filter Valve

A filter airlock valve is designed to be a low-cost solution to collecting dust.

  • Knife Rotary Valve

This type of rotary airlock valve has a knife attached to it which cuts up the material that is put into it and prevents the blockage of the valves. It is primarily used in the handling process of secondary fuel such as wood and plastics.

Applications of Rotary Airlock Valves

A rotary airlock valve is used as an airlock, a feeder or as a combination of both a feeder and an airlock. The airlock valve seals pressurized valves to prevent the loss of air from it while there is a continuous flow of materials. They are used for pollution control purposes in industries such as wood, paper, grain, paint, tobacco and so on. The main type of drop through valve is used in the handling of free-flowing materials that are dry or powdered such as grains and rice. The blow through type of rotary airlock valve is used to handle adhesive substances like cocoa, flour, milk powder etc. that may not be properly handled in a drop through type of rotary airlock valve.

Rotary airlock valve manufacturers generally suggest that regular maintenance of the rotary airlock valves or feeders be done properly. It is, of course, very important that the right kind of valve or feeder is chosen according to its designed purpose and what your need is, in order to achieve the maximum possible efficiency.

Few of us like to work under pressure while others like longer process for assured results in controlled way. The same is true for conveying system when material passes through them. Each material needs proper flow at its own pressure so that different sized materials can be regulated properly.

Different Types of Air Classifiers and It’s Benefits

There are different air classifiers available in market and they are used for different industrial applications to fulfill different objectives. In this article, we will focus on three major categories and how they are helpful for your business.

1. Gravitational Inertial classifiers

This air classifier uses gravity, air flow and directional changes for precision material cuts from 50 to 200 mesh. With inertial or centrifugal forces, metals are classified into different categories up to 200 mesh. The materials are fed inside through top of the chamber and they start traveling downwards. With the help of air, directional flow of materials get changed up to 120 degree or more.

At the exit phase, classifiers contain fine particles inside it. The particles that are too heavy and light in weight are separated by gravitational force. Now, air passes through curtains of falling particles and cuts down metal into evenly sized particles. The process is completed by eddy current in secondary air stream. The fabric filter is also used for final recovery of particles.

  • This makes sure there are no moving particles within flow stream.
  • Internal lining is made up of ceramic material and generally stronger
  • It reduces loading of materials and eliminates pond settling
  • The maintenance or operating costs has also been minimized to larger extent.
  • It reduces moisture content inside metals and minimizes alpha costs too.
  • The market opportunities have been increased for evenly sized particles.

2. Centrifugal Classifiers

Here centrifugal forces are applied to separate materials up to 100 microns. The drag forces are applied to separate fine particles where heavy particles are discharged through valve and only quality particles are obtained at exit phase. Now secondary air is passed through material to get even sized particles into circulating chamber. Now both air streams enter into cyclone to recover fine particles at the end.

3. Gravitational Industrial Classifiers

These Air classifier manufacturer India are engineered wisely to suit special industry needs where materials is fed from top of the classifier and passed through the chamber. The direction of flow gets changed from horizontal to angularity upwards for separation of particles. The coarse particles would release at the exit valve and fine particles would be recovered at the end.

Rotary Airlock Valve To Feed Pneumatic Conveying Systems

Components like rotary airlock valves are among the parts used for feeding pneumatic conveying systems, regardless the type- pressure or vacuum type. There are several other applications where these valves are employed for metering of a controlled feed rate. Selection of these valves is straightforward and need proper understanding about the product.

A rotary valve is a compact mechanical device used for discharging bulk powders or granules continuously under gravity flow. In other terms, rotary valves are among simplest machines that have only single rotating part; a multi-vane rotor that revolves in close contact in the housing.

Functionality of rotary valve-

  • It regulates product flow rate to the required/fixed rate
  • It maintains a gas pressure disparity between the outlet and inlet airlock
  • It performs like a Flame barrier
  • It acts as an explosion barrier
  • It acts as a process barrier

Being so useful in several terms, rotary valves do possess some limitations, which are as follows-

  • You should know that a rotary valve doesn’t develop product flow. It is used to pass the feed material that can fall into it and out of it under gravity.
  • You can find leaking of air or gas during the operation, which can affect the product flow and the performance of the machine.
  • If the pressure difference across the rotor is greater, it will be less predictable and less stable in efficiency.

Rotors of the valves are most variable parts that come in distinct range of alternative features. Most manufacturers design and intend rotors to bring flexibility to incorporate alternative features. A fewer manufacturers are there using castings for making cheaper rotors; however, their use is limited.

These are few important things that manufacturing unit shared to let you know about manufacturer of rotary airlock valves and their uses.
