Change the elastic force of elastomeric element 7, in order to the Opening pressure size of adjustment combination valve shaft 6.
The operation principle of the water attack release valve of the present invention is as follows：
1. valve is in the closed position, energy when being now hydraulic pressure superpressure by the elastic force of the regulation elasticity part 7 of adjusting nut 40
Push combination valve shaft 6 open, now the hydraulic pressure of intake tunnel 9 enters regulation chamber 22 from the inlet opening at combination valve shaft 6 center, due to regulation
The sectional area S2 of the corresponding piston upper wall 20 of chamber is more than the sectional area S1 of piston lower wall 18,（S2>S1,P1=P2）, valve is in hydraulic pressure
Itself lower closing；
2. when system overpressure, system pressure is more than the elastic force of elastomeric element 7, combination valve shaft 6 is open, and now combines valve shaft 6
The sealing very first time between piston lower wall 19 is destroyed, and the pressure very first time of intake tunnel 9 is released here；Meanwhile,
As combination valve shaft 6 is moved up, piston upper wall 20 is destroyed simultaneously with combining the sealing between valve shaft 6, adjusts the pressure of chamber 22
Power water is released rapidly, therefore the pressure in regulation chamber 22 is zero (P2=0) rapidly, and piston is under the hydrodynamic thrust of intake tunnel 9
Move up rapidly, the sealing of piston 5 and seal receptacle 3 is destroyed, and the big discharge opening of valve is opened rapidly, quick pressure releasing.
3. when system pressure reduction, less than setting pressure when, the elastic force of elastomeric element 7 acts on group more than pressure medium
Close on valve shaft 6, elastomeric element 7 promotes combination valve shaft 6 to move down reset, and upper wall, the lower wall for now combining valve shaft 6 and piston 5 are formed
Sealing, now the pressure of intake tunnel enters from the inlet opening in the middle of combination valve shaft 6 adjusts chamber 22, due to the section of piston upper wall 20
Product is more than the sectional area of piston lower wall, and under same hydraulic condition, the thrust of regulation chamber 22 is pushed away more than the hydraulic pressure of intake tunnel
Power, piston 5 starts to move down closing valve, and the speed that piston is moved down depends on adjusting the water intake velocity of the press water in chamber 22,
Therefore, can be with control valve closing velocity by the water inlet area of the inlet opening in the middle of 24 group valve for adjusting axle of throttling rod 6, it is to avoid
Valve closes valve water hammer because quick closedown is formed.
In summary, presently preferred embodiments of the present invention is these are only, the scope of the present invention should not be limited with this.It is i.e. all
It is the simple equivalent changes and modifications made according to claims of the present invention and description, all should still belongs to patent of the present invention
In the range of covering.
