Little Tips For Cryogenic Socket Weld Globe Valve
WORKING PRINCIPLE
Actually depends on the transmission mode of the valve, generally divided into the following three aspects:
1. Principle of pneumatic cryogenic valve: Inflate and deflate through the cylinder of the valve head to control the movement of the valve core driven by the transmission mechanism, and finally achieve the purpose of controlling the flow area and controlling the flow.
2. Principle of manual cryogenic valve: Generally, the movement of the spool is controlled by the handwheel, so as to control the flow area of the valve to control the flow.
3. The principle of the solenoid valve above the pneumatic valve: In this case, the exhaust and inflation of the cylinder are controlled by controlling the power on and off to control the transmission mechanism, and finally achieve the purpose of controlling the flow.
