Refer to Fig. 6-Fig. 8, a kind of operation principle of autocontrol valve in the utility model is：Fig. 6 is refer to, from this
The fluid (such as compressed air etc.) that a kind of autocontrol valve arrival end (i.e. the rear end of communication port 23) in utility model flows into
Pressure when being Fluid pressure P, fluid is successively after communication port 23, control mouth 34 between protruding block 33 and outlet 13
Gap is flowed out, and the pressure of the fluid in the gap being now placed between protruding block 33 and outlet 13 is Fluid pressure P, spring 5
Elastic force is equal to fluid matasomatism in the thrust (i.e. the area of Fluid pressure P x control pieces 3) of control piece 3, the front end of cylinder 22 with it is convex
Gap between bittiness 33 rear end keeps stablizing, from a kind of autocontrol valve port of export (i.e. outlet in the utility model
13 front end) pressure of fluid of discharge is also controlled by stablizing.
Referring to Fig. 7, flowed into from a kind of autocontrol valve arrival end (i.e. the rear end of communication port 23) in the utility model
The pressure of fluid (such as compressed air etc.) be excessive Fluid pressure P1 (excessive Fluid pressure P1 ＞ Fluid pressures P and fluid
The excessive Fluid pressure P1 of pressure P+ residual fluid pressure P2=) when, fluid is successively from protrusion after communication port 23, control mouth 34
Gap outflow between block 33 and outlet 13, at this time as shown in figure 8, gap between protruding block 33 and outlet 13
The pressure of fluid is excessive Fluid pressure P1, and the elastic force of spring 5 is less than fluid matasomatism in thrust (the i.e. excessive fluid of control piece 3
The area of pressure P1x control pieces 3), control piece 3 is moved rearwards until the front end of cylinder 22 supports the rear end of protruding block 33, makes to lead to
The Fluid Volume for crossing control mouth 34 reduces, so that from a kind of autocontrol valve port of export (i.e. outlet 13 in the utility model
Front end) pressure of fluid of discharge also reduces, until (being discharged from a kind of autocontrol valve port of export in the utility model
Mouthfuls 13 front end) pressure of fluid of discharge is controlled as Fluid pressure P.
Fig. 6 is refer to, is flowed when from a kind of autocontrol valve arrival end (i.e. the rear end of communication port 23) in the utility model
When the pressure recovery of the fluid (such as compressed air when) entered is Fluid pressure P, control piece 3 resets, the front end of cylinder 22 with it is convex
Gap between bittiness 33 rear end also resets, from a kind of autocontrol valve port of export (i.e. outlet 13 in the utility model
Front end) pressure of fluid of discharge is also controlled by stablizing.
From the above, it is seen that a kind of autocontrol valve in the utility model can control the pressure of fluid to keep steady
It is fixed.
In addition, a kind of arrival end of autocontrol valve in the utility model is located along the same line with the port of export, it is easy to
