How Do Rotary Airlock Valves Work?

Rotary airlock valves are an exceptionally unique form of rotary valves that allow manufacturers to process solid, liquid, and even semi-liquid material without having to worry for vane damages. Its unique seal lock technology ensures that the inlet and outlet materials do not come in contact with each other at any times of the process, thereby preventing overfeeding, loading, or processing of the goods.

Indeed, it is of no surprise that the most common industrial machines often bear their own rotary airlock valve in India. While, other machines like conveyor belts that do not come with an airlock, often end up being associated with one in order to enhance their output. Looking at the vast variety of functions performed by rotary airlocks, it is only natural to anticipate its working principle. The detailed process of its action can be described as follows:

Macro Structure and Process
Rotary airlock valve of India has a heavy-duty housing that is formed of a body, two end covers, a rotating rotor, and a drive package. The body has two same-sized ports for entry and exit of material respectively. At the structural level, the material is projected in the extended shafts directly from the containers.

Through the process of suction, it is then collected in the spaces of the V or U-shaped vanes that radiate towards the shaft walls. As rotors rotate on a set speed, every vane pocket transports its collected materials from one end to another while simultaneously filling the inlet materials in the empty pockets. The rotor is usually set at a typical speed of 22 rpm and hence, the material flows out of the outlet shafts at a very slow pace.

Micro Conditions and Working Principle
The seal lock system of the airlock valves is possible because of their closely knit and precise structure. The body and cover are made of strong metals that can withstand extreme air pressure, while the ends of the shaft covers are wielded into the system to ensure that no air is leaked from the body. It is also made sure that the rotor and housing are set on a straight alignment for the eight or more vanes to function efficiently.

Tight clearances are the factors that determine the airlocks’ output. Therefore, besides the geometry, the clearance range must be checked thoroughly. Once all the structural arrangements have been put in place, the operation of the airlock valve will automatically create a localized seal in the housing.

Rotary airlock valves of Indiaare also known for their dynamic capabilities. Since, they can easily handle a range of materials like sand, grains, spices, condiments, solid chemical goods, and fine dust particles of glass powder, calcite, and ash, they are used in many industries to perform material regulation tasks. Some of the industrial activities performed using airlocks aredetailed as follows:

Cyclone Discharge
When the rotary is placed under the cyclone, it can easily regulate the discharge of the solids from the containers and send controlled amounts into the conveyors, screws, etc.

Pneumatic Loading
Airlock valves can also feed into pneumatic conveying lines like silos, hoppers,and others. It is more efficient for such usages because it prevents air leakage and the subsequent material losses arising from it.

Filling Bulk Solids into Containers
Airlocks are also good tools to fill solids in bulk amounts (as per certain volumetric standards) in containers, drums, bags, and so on.

Rotary airlock valves of India are incredibly useful devices as they ease the way in which tedious industrial tasks are handled by workers. In this way, they not only save material losses but also facilitate essential manufacturing processes.
