Abstract
The utility model discloses a kind of water filling pump relief valve, including valve seat and spool, the valve seat lower end opens up water inlet, side opens up relief port, the lower part of the spool is mounted on inside valve seat, the top of the spool is cased with valve pocket, the valve pocket is fixedly mounted between valve seat and spool, the external stability of the valve pocket sets the valve of hollow-core construction to emit, the bottom fixed setting stepped piston of the spool, spool position between the valve pocket and piston is cased with spring, the lower end of the valve seat is the water inlet to match with piston, locating ring is fixedly installed on the cascaded surface of the piston, the locating ring compared with valve seat location open up annular groove, several buffer bars are fixedly installed between the annular groove and locating ring.The utility model is simple in structure, and the utility model is in the case where spool is automatically closed, due to using buffer bar so that spool taps power with valve seat to be weakened, and is prevented spool, piston, sealing ring from causing damages because power is excessive, is extended the service life of entire safety valve.
Description
Technical field
The utility model is related to safety valve technical fields, and in particular to a kind of water filling pump relief valve.
Background technology
Oil field generally uses spring (disc spring piece or spring) prepressing type with water filling pump relief valve, when waterflood-transmission line pressure is more than
During safety valve jumping up pressure, safe spool take-off, line pressure instantaneously reduces, but is automatically closed again under spring force effect,
Rise suddenly, the so safe multiple take-off of spool, spool tap overfrequency with valve seat, cause spool, valve base sealing line pressure again
Face, seals and other component are fragile, and valve is not closed completely, and generate high-pressure leakage, bring insecurity, the lighter causes driving belt
It skids, smolder, damage, severe one causes motor damage or circuit grade perils on fire.
Utility model content
The purpose of this utility model is that the defects of for the prior art and deficiency, provide a kind of water filling pump relief valve.
To achieve the above object, the technical solution adopted in the utility model is：A kind of water filling pump relief valve, including valve seat and
Spool, the valve seat lower end open up water inlet, and side opens up relief port, and the lower part of the spool is mounted on inside valve seat, wound
New point is：The top of the spool is cased with valve pocket, and the valve pocket is fixedly mounted between valve seat and spool, outside the valve pocket
The valve of portion's fixed setting hollow-core construction emits, the bottom fixed setting stepped piston of the spool, between the valve pocket and piston
Spool position be cased with spring, the lower end of the valve seat is the water inlet to match with piston, solid on the cascaded surface of the piston
Locating ring is set surely, the locating ring compared with valve seat location open up annular groove, it is fixed between the annular groove and locating ring
Several buffer bars are set.
Further, the buffer bar is folding sector structure, is completely disposed at after the buffer bar superposition in annular groove, described
Locating ring can be completely filled in annular groove after pushing.
Further, sealing ring is fixedly installed on the piston.
Further, valve pocket is run through in the upper end of the spool, and can be up and down in valve emits.
With the above structure, the utility model has the beneficial effect that：
The utility model is simple in structure, and the utility model, due to using buffer bar, makes in the case where spool is automatically closed
It obtains spool and taps power decrease with valve seat, prevent spool, piston, sealing ring from causing damages because power is excessive, extend entirely safety
The service life of valve.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Reference sign：
1 valve seat, 2 spools, 3 water inlets, 4 relief ports, 5 valve pockets, 6 valves emit, 7 pistons, 8 springs, 9 locating rings, 10 annular grooves,
11 buffer bars, 12 sealing rings.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The utility model is further elaborated in embodiment.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, a kind of water filling pump relief valve, including valve seat 1 and spool 2,1 lower end of valve seat opens up water inlet 3, and side is opened
If relief port 4, the lower part of spool 2 is mounted on inside valve seat 1, and the top of spool 2 is cased with valve pocket 5, and valve pocket 5 is fixedly mounted on valve seat
Between 1 and spool 2, the external stability of valve pocket 5 sets the valve of hollow-core construction to emit 6, the bottom fixed setting stepped piston of spool 2
7, the spool position between valve pocket 5 and piston 7 is cased with spring 8, and the lower end of valve seat 1 is the water inlet 3 to match with piston 7, living
Be fixedly installed locating ring 9 on the cascaded surface of plug 7, locating ring 9 compared with valve seat location open up annular groove 10, annular groove 10 with it is fixed
Several buffer bars 11 are fixedly installed between the ring 9 of position.Buffer bar 11 hits power decrease so that spool 2 strikes 1 with valve seat, prevents spool
2nd, piston 7, sealing ring 12 cause damages because power is excessive, extend the service life of entire safety valve.
In the present embodiment, buffer bar 11 is folding sector structure, and buffer bar 11 is completely disposed at after being superimposed in annular groove 10, is positioned
Ring 9 can be completely filled with after pushing in annular groove 10.
In the present embodiment, sealing ring 12 is fixedly installed on piston 7.Sealing ring 12 is caused close due to the effect of buffer bar 11
12 friction velocity of seal reduces, and so as to reduce damage, while good airproof performance, service life are long.
In the present embodiment, valve pocket 5 is run through in the upper end of spool 2, and can be up and down in valve emits 6.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover among the right of the utility model.
