ntroduction of Soft Start Unloading Valve:
Structural features:
1. The load discharge starting valve has compact structure, small volume, simple and convenient installation and elegant appearance.
2. The mechanical structure adopted by the load discharge starting valve does not need to be operated by electric appliances like electric valves, and it has good air tightness, safety and reliability.
3. After using this load-relief starting valve, the starting air sources such as fans and compressors under working conditions can be started directly with load without damaging fans. Thereby making the operation under working conditions simpler and safer.
4. The wood unloading starting valve has high sensitivity and short action time, and the whole action only takes a few seconds or tens of seconds. 5. Smooth operation, long service life and simple maintenance.
Scope of application:
The load relief starting valve is used in pipelines used by fans, compressors, etc., and is used to ensure that fans, compressors, etc. can be started directly with load without adding vent valves and other devices on pipelines. Therefore, it is widely used in many working conditions such as sewage treatment, pneumatic conveying, desulfurization and dust removal in power plants, chemical industry and so on.
Instructions for use:
1. The load discharge starting valve is installed at the outlet of the fan (the original three-way pipe can be changed into four-way pipe);
2. The opening and closing time (i.e. venting time) can be adjusted (from 10 to 60 "seconds). Adjust the bolt to rotate left and right to control the air inlet speed of air bag and the opening and closing height of valve and seat. 3. The connecting flange between the valve and the four-way valve is national standard 1OKG, and the installation form is clip-on type, which is suitable for horizontal and vertical installation.
4. If an engineering example needs to unload before stopping the fan, just connect the normally closed (conventional solenoid valve) solenoid valve to the interface of the load discharge starting valve.
