Specific embodiment
As shown in Fig. 1 ~ 3, a kind of low water drag hydraulic operated valve, it includes water inlet end valve body 1, water outlet valve body 2, spool 3 and sets
There is the valve deck 13 of control mouth 20.
It is equipped with water conservancy diversion support base 5 in water inlet end valve body 1, and is connected with water outlet valve body 2；4 are equipped in water conservancy diversion support base 5
The deflector I 21 of circle distribution；Spool 3 is placed in water conservancy diversion support base 5 and water outlet valve body 2, and is moved axially along valve body；Water outlet
The deflector II 22 of 7,4 circle distributions of universal driving shaft is respectively equipped with inside end valve body 2；One end of universal driving shaft 7 connects diaphragm 14,
Its other end is connected with interlocking bar 6, which connect with spool 3；Diaphragm 14 is installed on valve deck 13 and water outlet valve body 2
Between.
Wherein: the streamlined structure of spool 3.
The cross section of deflector I 21 and deflector II 22 is streamlined structure.
Water inlet end valve body 1 is connected by valve body bolt 9 with water outlet valve body 2, passes through valve body gasket 11 on the valve body bolt 9
It is connected with valve body nut 10.
Water shutoff circle 4 is equipped between water inlet end valve body 1 and water outlet valve body 2.
Universal driving shaft 7 is equipped with matched linkage Simmer ring 19, and passes through a pair of of location nut 17 and diaphragm
14 are connected.
Universal driving shaft 7 is connected by the pivot pin 18 that links with interlocking bar 6.
5 connecting rib cross section of water conservancy diversion support base is streamlined.
Interlocking bar 6 is connect by spool pin 8 with spool 3.
Diaphragm 14 is connected by valve deck bolt 12 with valve deck 13 and water outlet valve body 2, which passes through valve deck
Gasket 15 is connected with bonnet nut 16.
In use, pressure flow enters from water inlet end valve body 1, flowed out after flowing through spool 3 from water outlet valve body 2.Work as high pressure
Water flow is entered in the closed cavity formed by it with diaphragm 14 by the control mouth 20 on valve deck 13, and diaphragm 14 is in hydraulic pressure
It deforms under effect, driving universal driving shaft 7 is axially downward and then interlocking bar 6 and spool 3 is driven to move, finally by diaphragm
The deformation of piece 14 is converted into spool 3 along the flowing of valve body axial direction.When the hydraulic pressure for promoting diaphragm 14 to deform is sufficiently large, turn
Turn to the movement of spool 3 thrust be greater than water flow to the impulse force of spool 3 after, spool 3 is mobile to water inlet end valve body 1, finally and water shutoff
4 fitting cutting water-flowing path of circle, valve are closed immediately.When blocking high pressure water flow to enter control mouth 20, while making control mouth 20 and big
After gas phase is logical, spool 3 can be mobile to water outlet valve body 2 under 1 effect of water pressure of water inlet end valve body, and drives interlocking bar 6 and connection
Moving axis 7 moves, and is ultimately converted to the thrust perpendicular to 14 end face of diaphragm obliquely, so that the intracorporal water flow of chamber passes through control
Mouth 20 is discharged, and valve is opened immediately.
