Abstract
A kind of high-pressure injection pump Special valve body, including sleeve pipe, outer rim, internal thread and through hole are the utility model is related to, described sleeve pipe cylinder barrel shaped structure, internal thread is formed with the axial both ends inwall of sleeve pipe；The outer rim that radial end face is regular hexagon is coaxially formed with the axial both ends periphery of sleeve pipe, is formed with three through holes of radial equipartition in the middle part of sleeve pipe, three external pressure relief devices of through hole, the pressure in pressure relief device keeps constant；60 ° of chamfering is formed with the axial both ends of outer rim.The utility model is reasonable in design, and composition is simple and reliable, and low cost, fault rate are low, are easy to safeguard, and service life is grown, from the functional reliability and whole service life of lifting high-pressure injection pump.
Description
Technical field
The utility model is applied to high-pressure injection pump field, especially a kind of high-pressure injection pump Special valve body.
Background technology
High-pressure injection pump is in the milk for structure high pressure chemistry, using the professional machine of single liquid chemical grouting material, there is superelevation
Pressure is not required to pneumatic supply, carries the characteristics of power saving moving facilitates.Reached 0---50Mpa operating pressures in several seconds, have wide
Application prospect.At present, influence pump and realize that the factor of high-pressure injection pump is a lot, 1, that part bears pressure is big, flow cross ambassador its
Excessively stream aperture increases, it is difficult to ensure that high pressure chest does not ftracture under hyperpressure.2nd, work, transport under high-pressure work state for a long time
Dynamic component serious wear, influences service life.3rd, part dismounting is complicated, repairs difficulty, and cost is higher.
At present, high pressure check valve body is by manually adjusting flow according to pressure condition, reaching pressure in application valve body
Effect, valve body lack pressure relief, certain potential safety hazard be present, particularly under more extreme temperature environment even in itself
The danger of valve body cracking be present.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided a kind of high-pressure injection pump special service valve
Body, using metal structure as rack body, strengthen service life, mitigate abrasion.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of high-pressure injection pump Special valve body, including sleeve pipe, outer rim, internal thread and through hole, described sleeve pipe cylinder barrel shaped
Structure, internal thread is formed with the axial both ends inwall of sleeve pipe；Radial end face is coaxially formed with the axial both ends periphery of sleeve pipe
For the outer rim of regular hexagon, it is characterised in that：Three through holes of radial equipartition are formed with the middle part of sleeve pipe, three through holes are external
Pressure relief device, the pressure in pressure relief device keep constant；60 ° of chamfering is formed with the axial both ends of outer rim.
Moreover, three through holes selection installation one or three pressure relief devices.
Moreover, pressure relief device uses the pressure chamber of expansion tube type.
The advantages of the utility model and good effect are：
The utility model is reasonable in design, and composition is simple and reliable, and low cost, fault rate are low, are easy to safeguard, and uses
Long lifespan, from the functional reliability and whole service life of lifting high-pressure injection pump.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is to cut open left view in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of high-pressure injection pump Special valve body, including sleeve pipe 1, outer rim 3, internal thread 4 and through hole 2, described sleeve pipe cylinder
Tubular construction, casing length 138mm diameter 40mm, 1.5*45 ° of internal thread 4 is formed with the axial both ends inwall of sleeve pipe；
The outer rim that radial end face is regular hexagon is coaxially formed with the axial both ends periphery of sleeve pipe, is easy to make in assembling
It is fixed or is rotated with equipment such as spanners；
Innovative point of the present utility model is：
Three a diameter of 5mm of radial equipartition through hole 2 is formed with the middle part of sleeve pipe, the external pressure release dress of three through holes
Put, such as the pressure chamber of expansion tube type, the pressure in pressure relief device keeps constant, exceedes pressure chamber internal pressure when valve body internal pressure is excessive
When, adaptive guard effect is played to valve body to pressure chamber pressure release, the interior pressure of pressure chamber trimmer valve body by through hole.
According to structure needs, three through holes selection installation one or three pressure relief devices, casing size and clear size of opening
Equal proportion scaling is carried out as needed.
60 ° of chamfering is formed with the axial both ends of outer rim, effectively avoids connector from being pushed up in seam crossing in assembling
Pressure, lifts the collection density of assembly connection, and also allow for repairing in the future.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can
Can, therefore, the scope of the utility model is not limited to embodiment and accompanying drawing disclosure of that.
