Description
Technical field
The utility model is related to fluid machinery technical fields, specifically, being to be related to a kind of check valve for reciprocating pump.
Background technology
Effect of the check valve in reciprocating pump is the flowing of control fluid and cut-off, and low-pressure fluid is allowed to flow to high-pressure area,
High-pressure fluid is blocked to be flowed to area of low pressure.Reciprocating pump check valve is made of valve body, valve rubber and valve seat etc., and valve rubber is annular
Revolving body, valve rubber is coaxial to be nested on valve body, is consolidated with valve body, when closed check valve, valve rubber plays slow
Punching and sealing function.But current this one-way valve structures, in the intersection of valve rubber and valve body, valve rubber is a sharp edge and naked
It is exposed in fluid, in the case where the high speed of high-pressure fluid is washed away, sharp edge of the valve rubber at boundary line is easy to be washed and damaged, especially
, when containing particulate matter in high-pressure fluid, particulate matter is easy in the interface for being embedded into valve rubber and valve body, acceleration valve rubber for it
The breakage of sharp edge makes the valve rubber lost of life.
Utility model content
The purpose of the utility model is to overcome the shortcomings of above-mentioned traditional technology, provide a kind of list for reciprocating pump
To valve, the short deficiency of existing reciprocating pump one-way valve rubber service life can be made up.
The purpose of this utility model is reached by following technical measures：A kind of check valve for reciprocating pump, including
Valve seat, valve body and valve rubber, the valve seat are annular revolving body, and the valve body is connected with valve seat socket, and the valve rubber is located at
Valve seat top, the valve body lower portion, which is equipped with, is oriented to supporting leg, and the valve body is equipped with valve rubber installation groove, and the valve rubber is coaxially embedding
It is sleeved in the valve rubber installation groove of valve body, valve rubber lower part is equipped with sealing cone, the valve seat of the sealing cone lower part
Equipped with the matched valve base sealing conical surface of sealing cone shape, the valve body is equipped with the support conical surface, and the support conical surface is located at
The lower part of sealing cone, the valve seat of the support conical surface lower part is equipped with supports the conical surface with the matched valve seat of support conical surface shape,
In longitudinal axis the sealing cone be less than at a distance from the valve base sealing conical surface support conical surface and valve seat the support conical surface away from
From the valve body top is connected with spring, and the valve body top is equipped with spring positioning slot, and the spring is mounted on spring positioning slot
In.
Further, the valve body top is equipped with valve body Lift limited block.
Further, the number for being oriented to supporting leg is multiple.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that：
Valve body increases valve rubber installation groove, valve rubber is nested in the valve rubber installation groove on valve body, valve glue
Valve rubber is clipped in the middle skin installation groove by two planes up and down so that valve rubber is no longer sharp edge configuration at boundary line, is had
The problem of effect avoids valve rubber sharp edge is easily damaged at boundary line, extends the service life of valve rubber；
Valve rubber is coaxially nested in the valve rubber installation groove of valve body, and is fitted closely with valve rubber installation groove,
It is connected as an entirety with valve body, when check valve moves up and down, valve rubber and the interface of valve body are vertical with the direction of motion, no
It is easy embedded particulate matter, extends valve rubber service life；
Valve seat is equipped with the valve base sealing conical surface and valve seat and supports the conical surface, when valve body and valve rubber fall as a whole,
Valve rubber is sealed and buffers with valve base sealing taper-face contact first, effectively reduces the support conical surface and the valve seat support conical surface
Impact force；
After valve rubber is contacted with valve seat, valve body continues to move downward 1- with valve rubber under spring force and Fluid pressure effect
2mm, the support conical surface on valve body support taper-face contact with valve seat, play a supporting role, effectively control valve rubber decrement, keep away
Exempted from valve rubber because decrement is excessive fail the problem of；
Valve body top is equipped with spring so that valve body and valve rubber can integrally improve close in quick-make to valve seat
Seal effect.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
