Product Overview


Rotary airlock valve 

Product Description

1. Introduction

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.


A. Material feeding and discharging continuously.
B. Feeding rate can be controled by adjusting the rotary speed of the impellers. Feed rate is propotional to the rotary

     speed of impellers within a certain rotary speed range.
C. Certain airtightness,suitable for material discharging under differential pressure.
D. Material particles won’t get damaged.
E. Can be used for feeding and discharging of high temperature material.
F. Simple structure,easy maintenance.

3. 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.

The discharge valve on working: 
The discharge valve is generally installed at the bottom of the dust ash hopper. In order to ensure the connection of air leakage, it should often keep the height of the dust in the upper portion of the rotary discharge valve (storage). Because of the impeller rotates, the dust impeller turns on the two side often without dust. So it is easy to make the air leakage. The ssh column in order to keep a certain height, and unloaded not empty. The best way is the material level signal facilities equipped inside the hopper, and a chain with discharge valve of the motor.

4. Applicable material:

Widely used in cereal,food,feed,chemical,pharmacy,dust collection,drying and transportation industry.

Technical Data & How to confim the model and price?

To choose perfect rotary airlock valve , please confirm:
  1. 1. The capacity(Tons/Hour) 
  2. 2. The diameter of the inlet   and oulet flange 
  3. 3. Pressure : negative positive   ()Mpa?
  4. 4. What’s the material to be convey?The specific gravity  and  the moisture content
  5. 5. The voltage ?
  6. 6. Other special requirement, like brand of the motor ,height  of the rotary valve etc.
  7. 7. It is better if you have layout  drawing or sketch .
