Manufacturer supply Cast iron star discharge rotary valve Ash Discharge Valve

Short Description:

Material : Carbon steel
Media: Dust, small particle material
Color: Green/Blue
Customized support: OEM, ODM
Application: General

Airlock valve,also named discharge valve,star discharger,cindervalve,is an important equipment for pneumatic conveying system and dust removal system.

It is mainly used to discharge the material continuously from the tripper and dust collector,and make sure the inner pressure not exposed to atmosphere pressure evironment.
The airlock valve is made of gear motor,sealing element,impellers and rotor housing on which many rotating blades are set.It is capable of discharging powder,small particles,flaky or fibre continuously by the differential pressure of material.Now it has been widely used in chemical,pharmacy,drying,grains,cement,environmental protection and power industry etc.

Product Description

Star unloader is often used in pneumatic output system. for pressure output system or negative pressure output system, star unloader supplies material to conveying pipe uniformly and continuously.So as to ensure that the air and solids in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally, and at the same time, the upper and lower air pressure partitions of the unloader can lock the air.Therefore, star unloader is an important component commonly used in pneumatic conveying system.

Working Principle:

Material falls onto the blades and rotates with the blades to the outlet under the airlock valve.Material can be discharged continuously.
In pneumatic conveying system,the airlock valve can lock the air and supply material continuously. The low speed of the rotor and tiny space can prevent the airflow from reverse flow,and ensure a stable air pressure and regular discharge of the material.The arilock valve acts as the material discharger in the material collecting system.

      Product Description Pulse valves are divided into right-angle pulse valves and submerged pulse valves. Right angle principle: 1. When the pulse valve is not energized, the gas enters the decompression chamber through the constant pressure pipes of the upper and lower shells and the throttle holes in them. Because the valve core blocks the pressure relief holes under the action of the spring, the gas will not be discharged. Make the pressure of the decompression chamber and the lower air chamb...
