ESV electric material separation valve is used to control the material flow direction, and change the flow direction by adjusting the position of the valve core in the cylinder. Widely used in building materials, metallurgy, mining, light industry, grain and other industries. It is an ideal equipment to change the material flow direction in the solid grain and powder material conveying system.
The electric material separation valve is mainly controlled by the electric actuator, which is operated by the input 4-20 mA electrical signal.
The separation valve is made of high quality steel plate, with small size, light weight and small resistance. Driven by the Bernard electric actuator, you can remotely control the material flow rate.
Main structure and working principle:The electric material separation valve consists of four parts: electric actuator, shell, circular arc valve plate and lower inflation device.
When working, the electric actuator drives the circular arc valve plate through the central axis for a certain Angle swing to adjust the setting position, and the lower inflatable device makes the material above the breathable layer fluidized and is transported out along the discharge direction. So as to achieve the control of the material flow direction, the purpose of distributing materials.
Precautions for operation
1. Install the regulating valve on the air road before the gas enters the lower inflation device of the electric separation valve to control the air volume, and release water to the gas storage tank regularly according to the actual operation situation.
2. Before operation, let the low pressure air (the air filtered by the dryer) enter the breathable layer before feeding is allowed; when parking, stop the material first and close the air source; when parking for a long time, remove the material above the breathable layer for a long time.
3. The air source entering the breathable layer should be the roots fan.
4. It is not allowed to enter the mass, agglomeration and humidity＞ 1% materials and debris, to avoid the circular arc valve core stuck.
