The operation principle of the plain type pressure regulator valve of the present invention is as follows：
Reset condition：As shown in Figure 1, under this state, piston 7 and valve 8 are in sealed connection state.
Air-suction state：Compressed air reaches A chambers 111 from 101 air inlet of air inlet.Compressed air reaches C chambers 113 all the way, this
When, since piston 7 and valve 8 are still in the state of sealed connection, due to the sealing function of valve 8 so that the compression of C chambers 113 is empty
Gas is truncated herein；Another way compressed air is in A chambers, the active force for overcoming spring 3 downward so that shape occurs upwards for diaphragm 6
Become.Piston 7 is moved upwards by the first tabletting 5 and the drive of pressing plate 13.After piston 7 moves a distance, valve 8 is in spring 10
Under the action of with valve body 11 seal；Piston 7 is also sealed with valve 8 simultaneously.The pressure value of the compressed air of A chambers 111 persistently rises,
Piston 7 also continues to move upwards.After reaching pressure set points（By adjusting screw 1 come setup pressure value）, 7 He of piston at this time
Valve 8 is detached from, and the compressed air of C chambers 113 reaches B chambers, then is output to gas outlet I 103.
Exhaust condition：When the atmospheric pressure value of the compressed air of A chambers 111 starts to reduce, spring 3 and the first tabletting 5,
Under the gravity of pressing plate 13, the upward deformation of diaphragm 6 gradually sets back, and piston 7 is also begun to slowly toward decline.It is reduced to one
When set a distance, while piston 7 is sealed with valve 8.The atmospheric pressure value of A chambers 111 persistently reduces, and piston 7 overcomes spring 10 at this time
Upward effect, valve 8 is pushed away down so that the sealed connection of valve 8 and valve body 11 disconnects.The compressed air of B chambers 112 will
D chambers 114 can be reached, be then discharged in air by exhaust outlet 102.
The plain type pressure regulator valve, the position of gas outlet I 103 and quantity can be configured according to actual conditions, accordingly
