It covers equipped with spring, valve port is equipped between valve chamber and valve deck, flap is placed at valve chamber, and flap one end bears against spring, and flap is another
One end and sealing valve port coordinate, medium from import flow into valve body when, medium feed pressure is more than the elastic force of spring, then flap takes off
From sealing surface, medium is flowed into from into valve road, and by valve chamber, from outlet valve road outflow, when medium stops flowing, spring-return arrives
Position originally, flap reconstitute sealing surface with valve port, and medium is flowed into from into valve road, by valve chamber, from outlet valve road stream
Go out, when medium stops flowing, spring-return to original position, flap reconstitutes sealing surface with valve port, when medium reverse flow
When dynamic, medium feed pressure is with the active force that the spring force of spring is on equidirectional, therefore medium feed pressure can not take off flap
From sealing surface, so medium can not be from outlet valve road to valve road reverse flow is entered, so as to reach the work of medium one-way non-return
With.Existing three-port check damper does not have the function of pressure release, and much time using can cause security risk to pipeline, need to let out
Additionally mounted relief valve is then wanted in the case of pressure, improves the cost of installation.It is for this purpose, multi-functional only we have proposed a kind of threeway
Return valve.
