Description
Technical field
The utility model is applied to high-pressure injection pump field, especially a kind of high-pressure injection pump special joint.
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.0---50Mpa operating pressures were reached in several seconds, with wide
Application prospect.At present, influence pump realizes 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 difficult, cost is higher.
At present, the pressure that the Valve joint of high-pressure pump is carried in use is big, and impulsive force is strong, is easily damaged, and maintenance is more
It is difficult.
Utility model content
The purpose of this utility model, which is to overcome in place of the deficiencies in the prior art, to be connect there is provided a kind of high-pressure injection pump is special
Head, using metal structure as rack body, strengthens service life, mitigates abrasion.
The utility model solves its technical problem and takes following technical scheme to realize：
Valve element control assembly is installed, joint engagement is installed in valve body in a kind of high-pressure injection pump special joint, valve body
Input, valve ball is embedded between joint and valve element control assembly, it is characterised in that：The concrete structure of the joint, joint
Main body be a cylinder, the outer rim that a radial section is regular hexagon is formed with the middle part of joint, in the axial side of outer rim
Joint outer wall is formed with the external screw thread coordinated with valve body；The shaft core position of joint is coaxially formed with a slip casting passage, and slip casting passage is located at
End in valve body is formed with the valve ball embedding slot coordinated with valve ball, and the outer periphery of the embedding slot is uniformly formed with three semicircles even
Groove.
Moreover, being connected between connection valve ball embedding slot and slip casting passage by pressurization passageway, pressurization passageway and slip casting passage are same
Axle connection is set, and the diameter of pressurization passageway is smaller than the diameter of slip casting passage.
Advantage of the present utility model and good effect are：
The utility model reasonable in design, composition is simple and reliable, and low cost, fault rate are low, be easy to safeguard, and use
Long lifespan, from the functional reliability and whole service life of lifting high-pressure injection pump.
Brief description of the drawings
Fig. 1 is overall structure front view of the present utility model；
Fig. 2 is structural representation of the present utility model；
Fig. 3 be Fig. 2 in cut open right view.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch
The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
Valve element control assembly 4 is installed, the engagement of joint 1 is arranged on valve body 2 in a kind of high-pressure injection pump special joint, valve body
Input, be embedded with valve ball 3 between joint and valve element control assembly, valve element control assembly compresses or loosens valve ball so that
Close or open the slip casting passage of joint；
Innovative point of the present utility model is：
The concrete structure of the joint, the main body of joint is that a radial section is formed with the middle part of a cylinder, joint for just
The outer rim of hexagon, is easily installed force；Joint outer wall in the axial side of outer rim is formed with the external screw thread coordinated with valve body；
The shaft core position of joint is coaxially formed with a slip casting passage 8, and the end that slip casting passage is located in valve body is formed with and valve ball
The valve ball embedding slot 5 of cooperation, the outer periphery of the embedding slot is uniformly formed with three semicircle connectivity slots 6, and valve ball leaves sealing position
This three semicircle connectivity slots are also turned on the passage of both sides when putting, and increase connection area accelerates throughput；
In order to strengthen the pressure of infusion fluid, connected between connection valve ball embedding slot and slip casting passage by pressurization passageway 7, plus
Pressure passageway is set with slip casting passage coaxial communication, and the diameter of pressurization passageway is smaller than the diameter of slip casting passage.
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, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
Claims (2)
