Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, and following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Referring to Fig. 1-Fig. 4, the utility model embodiment includes dynamic valve plate 3 and quiet valve plate 2.
Valve flowing channel 4 is provided with the valve body 1 of valve.Valve flowing channel 4 is used for circulation medium.
Dynamic valve plate 3 is rotatably installed in the valve flowing channel 4 of valve body 1, and the outward flange of dynamic valve plate 3 and the chamber of valve flowing channel 4
Wall contact seals valve flowing channel 4.The rotation direction of dynamic valve plate 3 is its circumferential direction.
Quiet valve plate 2 is fixedly mounted in the valve flowing channel 4 of valve body 1, and the outward flange of quiet valve plate 2 and the chamber of valve flowing channel 4
Wall contact seals valve flowing channel 4.Quiet valve plate 2 and dynamic valve plate 3 fit together.Quiet valve plate 2 is wrapped with tetrafluoroethene.
Valve plate hole 5 is provided with dynamic valve plate 3 and quiet valve plate 2, valve plate hole 5 is the blade form of propeller.On dynamic valve plate 3
Valve plate hole 5 connected with valve flowing channel 4, the valve plate hole 5 on quiet valve plate 2 connects with valve flowing channel 4.Valve plate hole 5 on dynamic valve plate 3
Relative position between the valve plate hole 5 on quiet valve plate 2 is servo-actuated the rotation of valve plate 3 and changed, and moves the He of valve plate hole 5 on valve plate 3
There is misalignment position and lap position in the relative position between valve plate hole 5 on quiet valve plate 2；When dynamic valve plate 3 turns to one
During position, lap position is between the valve plate hole 5 on valve plate hole 5 and quiet valve plate 2 on dynamic valve plate 3, moves the valve plate on valve plate 3
Valve plate hole 5 on hole 5 and quiet valve plate 2 is overlapping, connects between the valve plate hole 5 on valve plate hole 5 and quiet valve plate 2 on so dynamic valve plate 3
It is logical, valve opening；When dynamic valve plate 3 turns to another position, the valve plate hole on the valve plate hole 5 and quiet valve plate 2 on valve plate 3 is moved
Misalignment position is between 5, the valve plate hole 5 on valve plate hole 5 and quiet valve plate 2 on dynamic valve plate 3 is staggered, on so dynamic valve plate 3
Do not connected between valve plate hole 5 on valve plate hole 5 and quiet valve plate 2, valve flowing channel 4 separates with regard to passive valve plate 3 and quiet valve plate 2, valve
Close.In this implementation, move valve plate 3 and rotate 35 °, move the can of valve plate hole 5 on the valve plate hole 5 and quiet valve plate 2 on valve plate 3 from mistake
Position position is changed into lap position.
