Valve seat body 1 is provided with relief valve 30, and valve seat body 1 is provided with the pressure release interface communicated with its interior intake tunnel,
Relief valve 30 is installed on pressure release interface, and relief valve 30 includes valve body 31, the second spring 32 being arranged in valve body 31 and ball
Body 33, the inside of valve body 31 are hollow, and the threaded one end 40 of valve body 31 is connected with lid 34, and the depth that lid 34 is embedded in valve body 31 can lead to
Screw thread 40 is crossed to adjust, lid 34 is provided with discharge outlet 35, and the other end of valve body 31 is provided with water inlet 5, formed in valve body 31 respectively with
The first pressure release passage 36 that water inlet 5, discharge outlet 35 communicate, the second pressure release passage 37, the first pressure release passage 36 and the second pressure release
For the centerline of passage 37 on same straight line, the interior diameter of the first pressure release passage 36 is more than the interior straight of the second pressure release passage 37
The junction inwall of footpath, the first pressure release passage 36 and the second pressure release passage 37 forms the step surface 38 of an annular, on step surface 38
Provided with seal washer 39, seal washer 39 is rubber gasket 39, and spheroid 33, second spring 32 are respectively positioned on the first pressure release passage
In 36, ball seat 41 is movably equipped with the first pressure release passage 36, spheroid 33 is fixed on ball seat 41, under normality, spheroid 33 with
The connected entrance that the mating reaction of seal washer 39 is blocked between the first pressure release passage 36 and the second pressure release passage 37, second spring 32 1
End is pressed against the inner face of lid 34, and the other end of second spring 32 is pressed against the inner face of ball seat 41.The setting of ball seat 41 can be certain
Degree under limit second spring 32 action direction, it is ensured that second spring 32 can in the vertical direction effect.Tune can be passed through
The position that lid 34 is embedded in valve body 31 is saved, so as to adjust the elastic force of second spring 32 to determine to be let out when hydraulic pressure is much
Pressure, i.e., vent pressure can freely be set.
The operation principle of relief valve 30 is as follows：
Control valve is opened, water enters in valve seat body 1, and when the hydraulic pressure in valve seat body 1 is too high, i.e. hydraulic pressure pressure is big
In the elastic force of second spring 32, at this moment hydraulic pressure can oppress spheroid 33 and be moved to the direction away from the second pressure release passage 37, and first lets out
Opened between the pressure release passage 37 of pressure passageway 36 and second, i.e., discharge outlet 35 is opened, and ponding can pass through the discharge outlet on lid 34
35 discharges；After the hydraulic pressure in valve seat body 1 is reduced to normal pressure, i.e., hydraulic pressure pressure is less than the elastic force of second spring 32, this
When second spring 32 elastic force can oppress the returning movement of spheroid 33 so that spheroid 33 pushes down seal washer 39, and the first pressure release is led to
Connected entrance between the pressure release passage 37 of road 36 and second is blocked, i.e., discharge outlet 35 is finally closed.
Relief valve 30 is set, when the water in water pipe channel is entered in valve seat body 1, when hydraulic pressure is excessive, passes through relief valve
30 can carry out pressure release, the pressure stability of water inlet 5 of valve seat body 1, meet actual use needs, hose coupling will not superpressure, really
Fire-fighting work has been protected to be normally carried out.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work, it should all belong to the covering scope of the utility model patent.
