Description
Technical field
The utility model relates to a kind of valve rubber of anti-high pressure.
Background technique
Valve rubber is also known as valve rubber, and valve rubber is the sealing element being mounted on valve (or valve).Oil fracturing valve
Rubber is mounted on component-valve assembly of fracturing unit truck high-pressure plunger pump that (valve assembly includes valve body, valve seat, valve
Rubber) sealing element.High-pressure plunger pump is the working host of fracturing unit truck, and pressure break is very high to the technical property requirements of valve rubber,
Should have the characteristics that anti-high pressure, corrosion-resistant, abrasion resistance is strong.When equipment is run, valve rubber is bearing high pressure, corrosion and silt particle
While washing away, also to play the role of sealing.
After existing valve rubber use there are the problem of: high pressure effect under, valve rubber outer ring is easy compression diameter
To becoming larger, cause outer ring badly damaged；Under the double action of high pressure and sand grains, the intradermal circle of the valve rubber contacted with valve seat
Badly broken on side.The existing anti-high-voltage performance of valve rubber is poor, is easily damaged, short using the time.
Utility model content
In view of the deficiencies of the prior art, the utility model is intended to provide a kind of valve rubber of anti-high pressure, by valve
Groove is set on the outer ring of rubber, avoids high pressure from making the compression of valve rubber outer ring is radial to become larger, causes outer ring badly damaged；It is close
It seals inclined-plane and different first inclined-plane of two sections of angles and the second inclined-plane is set, when just starting to be pressurized, positioned at first inclined-plane in outside
First contacted with valve seat, continue compression after be just depressed into the second inclined-plane, because the second inclined-plane with the angle on valve body inclined-plane identical and base
On this on an inclined-plane, so the pressure that the second inclined-plane is received is supported by valve body inclined-plane, the second inclined-plane is not pressed substantially
Power, for this purpose, the second inclined-plane will not damage.
The utility model is achieved through the following technical solutions.
A kind of valve rubber of anti-high pressure, circlewise, the valve rubber skin includes inner ring, outer ring and close to the valve rubber
Inclined-plane is sealed, the inner ring is coupled with valve body, and the sealing inclined-plane and valve seat cooperation seal, which is characterized in that described
Outer ring is equipped with groove.
Preferably, the groove is circular groove or rectangular recess.
Preferably, one end of the groove is concordant with the one end on non-tight inclined-plane of the valve rubber, makes the groove
Form a ladder.
Preferably, sealing inclined-plane includes two sections of inclined-planes, and the angle A positioned at first inclined-plane in outside is less than the valve seat
Angle C, the angle B positioned at the second inclined-plane of inside are equal to the angle C of the valve seat.
Preferably, the angle A on first inclined-plane is 12 °~23 °.
Preferably, the angle C of the valve seat is 25 °~40 °.
Compared with prior art, the utility model has the advantages that: the utility model on the outer ring of valve rubber by setting
Groove is set, avoids high pressure from making the compression of rubber outer ring is radial instead to become larger, causes outer ring badly damaged；The utility model sealing inclined
Different first inclined-plane of two sections of angles and the second inclined-plane is arranged in face, when just starting to be pressurized, positioned at outside the first inclined-plane first with
Valve seat contact continues just to be depressed into the second inclined-plane after being pressurized, because the second inclined-plane is identical as the angle on valve body inclined-plane and substantially
On an inclined-plane, so the pressure that the second inclined-plane is received is supported by valve body inclined-plane, the second inclined-plane is not under pressure substantially, is
This, the second inclined-plane will not damage.
