Description
Technical field
This utility model is related to a kind of plunger pump one-way valve modular construction, in particular it relates to a kind of plunger of convenient dismounting
Pump check valve assembly.
Background technology
Plunger displacement pump is an important device of hydraulic system, and it, is led to unidirectionally by the operation principle of liquid using check valve
Cross plunger to move back and forth in cylinder body, make the volume of seal operation cavity volume change to realize the water that absorbs water, presses, and realize high pressure
Water one-way flow.Plunger displacement pump has the advantages that rated pressure height, compact conformation, efficiency high and Flow-rate adjustment are convenient, extensively should
The occasion for adjusting is needed for high pressure, big flow and flow, in such as cleaning machine, engineering machinery and ship.
The check valve assembly of existing plunger displacement pump, when check valve assembly is pulled out from unidirectional valve opening, needs overcome sealing
Circle realizes the dismounting of check valve assembly with the frictional force of the unidirectional valve opening border of pump cover, and this kind of dismounting mode have to use it is special
Instrument.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of plunger pump one-way valve of convenient dismounting
Component, realizes and just can normally dismantle check valve assembly using conventional method.
To reach above-mentioned purpose, the technical scheme adopted by this utility model is as follows：
A kind of plunger pump one-way valve component of convenient dismounting, including spring, valve bonnet, valve seat, valve block, sealing ring, the valve
Cover upper center is provided with screwed hole, and valve bonnet lower end is coordinated with valve seat installs, and sealing ring, valve seat upper table are equipped with the middle part of valve seat outer ring
Face is coordinated with the face seal of valve block following table, by spring supporting between valve block upper surface and valve bonnet upper end inner surface, is revolved by bolt
Check valve assembly is taken out from plunger pump cover by entering the screwed hole.
Valve seat outer ring upper end is provided with back-off flange, and the groove for sealing ring assembling, valve seat are provided with the middle part of valve seat outer ring
Upper surface is provided with taper seat, and the valve block lower surface is provided with spherical, taper seat and the valve block lower surface of the valve seat upper surface
Spherical face seal coordinate.
The valve bonnet lower end is provided with the back-off flange mistake of the full circle for coordinating with valve seat, valve bonnet lower end full circle and valve seat upper end
It is full of cooperation, links closely to form a black box.
The check valve assembly is assemblied in the unidirectional valve opening of piston pump cover, and valve seat lower end is matched somebody with somebody with check valve bottom hole plane
Conjunction, the sealing ring at the central slot of valve seat outer ring and unidirectional valve opening border compressed fit.
Plunger pump one-way valve component provided by the utility model, by simple structure, solves check valve assembly and exists
Specific purpose tool must be used during dismounting, inconvenient problem is dismantled.
Description of the drawings
By reading the detailed description made to non-limiting example with reference to the following drawings, other spies of the present utility model
Levy, objects and advantages will become more apparent upon：
Fig. 1 is the structural representation of check valve assembly provided by the utility model；
Fig. 2 is assemblied in the structural representation in the unidirectional valve opening of pump cover for check valve assembly.
Specific embodiment
This utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area
Technical staff further understands this utility model, but does not limit this utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, some changes and improvements can also be made.
These belong to protection domain of the present utility model.
Shown in Fig. 1, the plunger pump one-way valve component of convenient dismounting provided by the utility model, including spring 1, valve bonnet 2,
Valve seat 3, valve block 4, sealing ring 5.
2 upper center of valve bonnet is provided with for dismantling the screwed hole 6 for using, and 2 lower end of valve bonnet is provided with for whole with what valve seat 3 coordinated
Circle.3 outer ring upper end of valve seat is provided with back-off flange, and the groove for the assembling of sealing ring 5, valve seat upper surface are provided with the middle part of 3 outer ring of valve seat
It is provided with taper seat.4 lower surface of valve block is provided with spherical.The taper seat of 3 upper surface of valve seat and the spherical face seal of 4 lower surface of valve block
Coordinate.2 lower end full circle of valve bonnet and the back-off flange interference fit of 3 upper end of valve seat, link closely to form a black box.On valve block 4
Supported by spring 1 between 2 upper end inner surface of surface and valve bonnet.Groove assembling sealing ring 5 in the middle part of 3 outer ring of valve seat.Such as Fig. 2
Shown, check valve assembly is assemblied in the unidirectional valve opening of pump cover, and 3 lower end of valve seat is coordinated with check valve bottom hole plane, 3 outer ring of valve seat
Sealing ring 5 at central slot and unidirectional valve opening border compressed fit.
In unloading process, it is connected with the locking of screwed hole 6 merely with standard bolt (bolt in GB), you can by unidirectional valve group
Part is very easily taken out from the unidirectional valve opening of pump cover.
Above specific embodiment of the utility model is described.It is to be appreciated that this utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or change,
This has no effect on flesh and blood of the present utility model.Spy in the case where not conflicting, in embodiments herein and embodiment
Levy and arbitrarily can be mutually combined.
