Description
Technical field
The present invention relates to valving field, specifically a kind of angie type reaction balance decompression venting valve.
Background technology
It is right in the prior art since pipeline burst phenomenon caused by inlet and outlet pressure difference happens occasionally in pipeline
This proposes kinds of schemes and solves this technical problem, such as Chinese utility model patent CN206889787U discloses a kind of decompression
Voltage stabilizing valve arrangement, including connector, adapter, excessively water column, piston, spring；The connector and adapter, which are matched, synthesizes a set of set
The shell of water column, piston, spring is crossed, the upper end of the connector corresponds to water inlet end, and the lower end of the adapter corresponds to
Water end (W.E.)；Described to cross water column and connector secure fit, the middle and lower part of the side wall for crossing water column is formed with several circumferentially
Water hole, water inlet end and water outlet end pressure can be adjusted so that the pressure of water inlet end and water outlet be in dynamic equilibrium, but still tool
It has a disadvantage that：Dynamic regulation structural pressure is adjusted unstable in the prior art, and its adjusting pressure difference cannot be excessive, works as pressure
When difference is excessive, adjustment effect cannot be reached, pipeline still has explosion dangerous.
Invention content
It is existing to solve technical problem to be solved by the invention is to provide a kind of angie type reaction balance decompression venting valve
Defect present in technology.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
A kind of angie type reaction balance decompression venting valve, including valve body and the spool positioned at valve inner, the valve body
It is fixedly arranged above valve seat, the lower section of the valve seat is provided with valve base sealing pad, the side setting of the valve body with respect to spool position
There is entrance, outlet is equipped at the lower exit port valve deck of valve body, the lower section for stating valve inner spool is diaphragm control chamber, described
It is located in diaphragm control chamber below spool, the lower end of spool is fixedly connected with diaphragm, and the diaphragm is pressed with power transmission pin connection
Power is transmitted；On the outside of valve body, power transmission pin top is connect the power transmission pins position with spring base；
Further, the diaphragm upper and lower is respectively diaphragm pressing plate and diaphragm pressure pad, the diaphragm pressing plate and pressing diaphragm
Diaphragm is clamped and fastened on spool lower end by pad；
Further, there is spring, the spring pressure head to pass through between the spring base and the spring pressure head of top end of the valve body
The hex nut of upper part adjusts position, and then adjusts the pressure that power transmission pin is subject to；
Further, the spool is provided with o-ring one with valve body junction, and valve seat is provided with O-shaped with valve body junction
Ring two；
The beneficial effects of the invention are as follows：Due to this valve outlet pressure control do not influenced by inlet pressure, so no matter into
Mouth pressure has much variation outlet pressures all unaffected.A stable outlet pressure can be exported.

Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figure 1, a kind of angie type reaction balance decompression venting valve, including valve body 7 and the spool inside valve body 7
5, the valve body 7 is fixedly arranged above valve seat 11, and the lower section of the valve seat 11 is provided with valve base sealing pad 8 with respect to 5 position of spool,
The side of the valve body 7 is provided with entrance, and outlet is equipped at the lower exit port valve deck 1 of valve body 7,7 inner spool 5 of the valve body
Lower section is diaphragm control chamber, and 7 lower section of the spool is located in diaphragm control chamber, and the lower end of spool 7 is fixedly connected with diaphragm 3, institute
It states diaphragm 3 and connect progress pressure transmission with power transmission pin 9；The power transmission pin 9 is located at 7 outside of valve body, 9 top of power transmission pin and spring base
12 connections；
More specifically, 3 upper and lower of the diaphragm is respectively diaphragm pressing plate 4 and diaphragm pressure pad 2, the diaphragm pressing plate 4 and film
Diaphragm 3 is clamped and fastened on spool lower end by piece pressure pad 2；
More specifically, there is spring 13, the spring pressure between the spring pressure head 14 on 7 top of the spring base 12 and valve body
First 14 adjust position by the hex nut 15 of upper part, and then adjust the pressure that power transmission pin 9 is subject to；
In order to improve the sealing performance of entire pressure maintaining valve, the spool 5 is provided with o-ring 1, valve with 7 junction of valve body
Seat 11 is provided with o-ring 2 10 with 7 junction of valve body；
Concrete operating principle：This valve mainly by valve body, spool, valve base sealing pad, diaphragm, spring, etc. parts form, lead
It is to reduce the high hydraulic pressure in upstream to act on, and downstream is made to obtain a stable relatively low pressure.Its principle is when we are logical
When crossing nut 15 and presetting outlet pressure, high pressure water enters from valve inlet, and downstream diaphragm control is flowed to by hollow spool 5
Chamber, when downstream, which has, reaches spring setting pressure.Pressure forms active force by the effect of diaphragm 3, through power transmission pin 9 and spring base
12 act on spring 13, and spring is compressed, and spool 5 moves up and contacts sealing with valve base sealing pad 8, ensure that downstream pressure is stablized.
When downstream pressure declines, spring 12 pushes diaphragm 3 to move down, and band movable valve plug 5 is detached from valve base sealing pad 8, and high pressure water passes through spool stream
Enter diaphragm control chamber.The opening of spool 5 discharges water when outlet pressure is low in this way, and pressure is closed when reaching setting value, remains outlet
Pressure stability.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
