Description
Technical field
The utility model relates to casting techniques field, in particular to a kind of pump valve casting.
Background technique
Pump valve is the general designation of pump and valve.The non-valve for the valve of pump or with pumping action.Pump and valve usually contact
Together the reason of is use occasion.That is having the place of pump generally has valve, some places generally require to pump.They are
Place for liquid conveying.
Now pump valve in the art includes valve seat, spool and spring, and spool is pressed on valve seat by spring, and in closed valve seat
Influent stream road.But spring can only be buffered vertically, can not alleviate lateral power, be easy to cause spring lateral shift for a long time, so that
Spool can not completely enclose influent stream road, to influence leakproofness.
Utility model content
The purpose of the utility model is to provide a kind of pump valve casting, to solve the problems, such as to mention in above-mentioned background technique.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of pump valve casting, packet
Valve body, valve seat, valve rod and spool are included, the valve body is fixedly connected with valve seat, and the valve seat offers influent stream road, described
Valve body offers out runner, and the intersection in the influent stream road and runner out is river conjunction, and the valve rod is matched with valve spool
Conjunction, and control valve core and river conjunction sealing cooperate or separate river conjunction, offers in the valve body for valve rod reciprocating movement
Valve chamber is provided with the spring that valve rod resets spool to river conjunction in the valve chamber, and the spring pocket is set to valve rod,
The side of the valve rod towards spool is fixedly installed spring base, and the lateral wall of the spring base is circumferentially arranged buffering
Part is simultaneously offseted by the inner sidewall of the bolster and valve chamber, and annular groove, the annular groove are circumferentially offered in the bolster
Inside be provided with several little springs, one end of each little spring and the inner wall of annular groove is mutually fixed, the other end and spring base it is outer
Side wall offsets；The side of the valve body towards valve seat offers upper seal groove, is bonded with sealing in the upper seal groove
The position of adhesive tape, the corresponding upper seal groove of the valve seat offers lower seal groove cavity, and lower sealing is bonded in the lower seal groove cavity
Adhesive tape, the upper seal groove and lower seal groove cavity constitute dislocation cooperation
By using above-mentioned technical proposal, valve chamber cooperates for placing spring and valve rod, valve rod and spring, can be in spring
Elastic acting force moves downward valve rod, while pushing spool mobile towards river conjunction, and spool and river conjunction is finally made to offset reality
Now sealing cooperation.Valve seat is provided with influent stream road, and valve body is provided with out runner, and fluid media (medium) can enter from influent stream road and from runner out
Outflow.When valve body is in close state, the elastic acting force of the spring above spool is greater than in the influent stream road below spool
Hydraulic pressure moves down spool and blocks river conjunction, and fluid media (medium) can not be flowed out from runner out at this time；When valve body is in opening state
When state, a large amount of fluid media (medium)s are injected into influent stream road, become larger the hydraulic pressure in influent stream road, until the elasticity for being greater than spring is made
Firmly, and spool is pushed to be lifted, makes to show that runner is connected with influent stream road, fluid media (medium) can be flowed out from runner out.In addition,
The inner sidewall of spring base and valve chamber offsets, and plays position-limiting action, can be effectively prevented from spring in occurring lateral shift in valve chamber, together
When in several little springs are arranged in spring base, brought lateral active force when valve body shakes, Jin Erzeng can be effectively relieved
The service life of long spring.In addition, valve body and valve seat are fixed by screw, therebetween due to production technology the problem of inevitably go out
Existing gap, so the utility model is provided with seal groove and lower seal groove cavity, when valve body and fixed valve seat, in upper seal groove
Lower sealing joint strip in upper sealing joint strip and lower seal groove cavity abuts against and is formed sealing, cooperates valve body with valve seat closer, has
Gap between effect compensation valve body and valve seat, sealing performance are more preferable.
Be further arranged to: the bolster is sheathed on the lateral wall of spring base, and the bolster is flexible material.
By using above-mentioned technical proposal, bolster is flexible material, convenient for bolster to be assemblied on spring base, is improved
Production efficiency, and do not have mechanical structure the problems such as so that it will not failures, long service life.In addition, bolster and valve can be reduced
The frictional resistance of cavity wall reduces bolster and the probability that serious wear is even damaged occurs, improves the service life of bolster.
Be further arranged to: the periphery of the bolster is provided with erosion shield.
By using above-mentioned technical proposal, it is contemplated that the fluid media (medium) in the utility model may have corrosivity, delay
Stamping is easily corroded and damages, so bolster periphery be arranged erosion shield, prevent fluid media (medium) to bolster into
Row corrosion failure.
Be further arranged to: the valve body is fixedly installed sealing convex block, the valve seat pair towards the side of valve seat
The position that convex block should be sealed offers secondary seal slot, silica gel ring is bonded in the secondary seal slot, the sealing is convex
Block presses silica gel ring.
By using above-mentioned technical proposal, the leakproofness between valve body and valve seat is further increased, is existed using silica gel ring
It is easier to generate the characteristic of flexible deformation under the action of clamping load, matches sealing convex block with the silica gel ring disk in secondary seal slot
Close it is even closer, to further seal.Meanwhile then be subject to seal groove and lower seal groove cavity, constitute between valve body and valve seat
Double-layer seal, substantially increases leakproofness and safety, effectively prevents interior leakage problem.
It is further arranged to: offering the first filled cavity and the second filled cavity, the valve seat outer wall in the valve seat
On be provided with the first filling-valve and the first dump valve being connected with the first filled cavity, be provided on the valve seat outer wall and the
The second filling-valve and the second dump valve that two filled cavities are connected, first filling-valve and the second filling-valve are located at
The upper end of one filled cavity and the second filled cavity, first dump valve and the second dump valve are located at the first filled cavity and the
The lower end of two filled cavities.
Covibration may be generated, valve is caused when fluid media (medium) washes away influent stream road by using above-mentioned technical proposal
There is gap in sealing at core and river conjunction, so that sealing performance reduces.So the utility model be provided with the first filled cavity and
Second filled cavity changes consolidating for valve seat itself by being injected separately into different filling liquids in the first filled cavity and the second filled cavity
There is frequency, greatly avoids the generation of covibration.In addition, the first filling-valve and the second filling-valve be located at the first filled cavity and
The upper end of second filled cavity, the first dump valve and the second dump valve are located at the lower end of the first filled cavity and the second filled cavity,
The self gravity of filling liquid is utilized to the greatest extent, filling liquid is made to need the resistance overcome minimum in injection and discharge process.
