The rotor of a rotary valve is a spinning element that typically manages the bulk material flow from downstream to upstream devices. There is a drive motor that the Industrial Boilers Manufacturer in India links to the valve motor powers for rotation. In fact, there is a possibility of connecting various rotary valves.
In this blog, we will have sufficient data about the working principle and different applications of rotary valves.
What Are Rotary Valves?
It is a pneumatic valve that basically manages and measures the flow of the powders or the granular bulk. People also denote it as rotary feeders, rotary airlocks and many other things. Rotary Feeder for Boiler Furnace in India supplies the material into the valve with the help of a hopper or even other inlets. The valve rotor generally processes it and after that deposits discrete packets onto the conveyor system. All of this is possible with just a little bit of pressure loss. Most of the time people commonly employ rotary valves in air conveyor systems in order to decrease the pressure loss across the valve. Besides that, people also use them to meter materials at a regulated flow rate. They almost solely act as explosion or flame barriers, airlocks, process isolators and many more things in the air system.
With the help of rotary feeders, you can transport dry to somewhat sticky goods. They also have a wide range of uses in the food and chemical industry. Additionally, they also use it for pharmaceutical, plastic, and other production industries.
How Do the Rotary Valves Work?
The four main essential components of a rotary valve include a rotor, an outer housing, a rotor bearing or seal and a drive. They housed all the inlet or outlet ports and the safe passage for material passing through the valve in the housing. With the help of a rotor bearing, you will be able to keep the rotor in place. Whereas the bearing and the shaft seal help in keeping the practices out of the valve inner housing.
The manufacturers also mount the driving mechanism (they are technically electric motors) on the exterior of the rotor shaft. Besides that, they also regulate the rotor’s rotation direction and speed. They feed the product into the valve, then collect it in equal pockets between the rotor vanes and also distribute it evenly at the outlets. These rotor vanes technically have a tight clearance with the preventing material or pressure losses and the housing through maintaining pressure differentials and the valve.
You will be able to get the rotary valve in various shapes and sizes and each one of them is suited for a specific reason. They also customize each component to fit particular requirements.
Applications Of Rotary Valves?
- To empty a silo
The rotary valve control devices like screw feeders, conveyors, mixers and other container systems are located beneath the silo.
- Rotary valve cyclone discharge
They utilize a rotary valve under a cyclone to control the solid bulk discharge from the cyclone under vacuum or pressure.
