Pneumatic pneumatic valve is cut off by the thin film actuator or piston type actuators with different kinds of pneumatic valves, cut off the pneumatic valve is mainly used for a variety of different conditions for quick cut, common to cut off the pneumatic valve types mainly include thin film cut pneumatic valve, piston to cut off the pneumatic valve, pneumatic valve, electromagnetic fast cutting fluid pneumatic emergency cut-off valve, etc.
Then we should be how to correctly use pneumatic emergency cut-off valve?
pneumatic emergency cut-off valve working principle is as follows:
1. When gas source to the pressure, the forerunner of pneumatic valve open, with the pneumatic valve guide groove is between inlet side pressure relief, to reduce the opening and closing force, make the energy saving pneumatic valve is open and rapidly, when the pneumatic air pressure relief valve is closed automatically.
2。 This pneumatic valve is equipped with easy melt automatic cutting device, when the environment temperature reaches to 75 + 5 ℃ fusible alloy melt, the cylinder pressure relief, make the pneumatic valve automatically shut down.
3。 This pneumatic valve adopts the ptfe sealing surface, sealing is good.
4。 This pneumatic valve drive part and pressure pneumatic valve body separate, easy to change the cylinder and cylinder parts, ring.
5。 The main moving parts adopt pneumatic valve contains chromium stainless steel, corrosion resistance is good.
use pneumatic emergency cut-off valve should pay attention to the following:
1. Custody of the individual foreign pathway of the pneumatic valve with a plug or cover closed, stored in a dry indoor ventilation, long-term storage should be regularly check, remove dirt, and coating on the surface of the processing rust-proof oil, prevent rust.
2。 Before installing this pneumatic valve clearance should be clean and tighten the screw thread joint.
3。 Principle of the pneumatic valve adopts pneumatic valve check, only one-way truncation, when installation should pay attention to the pneumatic valve, to protect as pneumatic valve at the end of the entrance.
4。 Order to be marked the flange sealing surface, pressure rating and connection standard.
that is a little knowledge about pneumatic emergency cut-off valve, hope to be of help!
