It is obliquely installed.
Further, the periphery of valve seat 8 is preferably outer cone disc；The inner headed face of valve seat 8 is preferably inner cone disc.
Further, as shown in Fig. 2, the top of valve rubber 10 is provided with a faced washer 9, when valve deck 5 and valve seat 8 are intact
When assembling, the upper surface of faced washer 9 is used in sealing contact with the bottom face of valve deck 5.
Further, as shown in Fig. 2, the top of valve body 7 is equipped with cushion rubber bumper 6, cushion rubber bumper 6 is used in valve deck 5 and valve
Seat 8 is intact when assembling, in sealing contact with the interior top end face of valve deck 5.
Further, as shown in Fig. 2, suction inlet 12 is taper suction inlet, and the stub end of taper suction inlet and valve seat 8
Bottom face is concordant, and the taper of taper suction inlet is preferably 30 ° -45 °.
Further, as shown in Fig. 2, the bottom face center of valve body 7 offers indent disc 13.In the present embodiment, valve body 7
Bottom face be spherical surface, the periphery of valve body 7 is cylindrical surface, and the top end face of valve body 7 is plane, and above-mentioned spherical surface, cylindrical surface with
It and is to be connected smoothly between top end face.
Further, as shown in Fig. 2, the inner tip of valve seat 8 is provided with internal screw thread, the bottom end periphery setting of valve deck 5
Have and is threadedly coupled with valve seat 8 by internal screw thread and external screw thread with the matched external screw thread of internal screw thread, valve deck 5.
Further, the napex of valve deck 5 is circumferentially-spaced offers 4-6 logical gains, is preferably provided with 4 logical gains and interval
It is uniformly distributed.
Further, it as shown in Fig. 2, circumferentially spaced on the periphery of valve deck 5 be equipped with 4-6 sump pit 14, preferably sets
It sets 4 sump pits 14 and interval is uniformly distributed.Wherein sump pit 14 is preferably rectangle sump pit, and four angles of rectangle sump pit are equal
For knuckle, and 14 lower part of sump pit is equipped with 20 ° -35 ° of intake chute angle, in order to which drain is smooth.
Concrete operating principle explanation is made to the present embodiment below.
As shown in Fig. 2, valve body 7 is in freely falling body under normal conditions and the state closed with valve rubber 10, valve deck 5 are set
It sets in the top of valve seat 8, and is threadedly coupled with valve seat 8, valve deck 5 plays guiding and limiting valve body 7 up and down when valve body 7 works and opens
Open the effect of height.The bottom face of valve body 7 is set as spherical surface, and side is cylindrical surface, when the bottom end spherical surface of valve body 7 is located at sump pit
When at 14 inner opening, sump pit 14 is open greatly, and fluid flow is big, and valve body 7 more moves up, and the opening of sump pit 14 is bigger,
Fluid flow is bigger；Conversely, 7 position of valve body closer to bottom, is just connect by the inner opening on the side cylindrical surface of valve body 7 and sump pit 14
Touching, and has certain plugging action to inner opening, so that valve body 7 more moves down, sump pit 14 is open smaller, and fluid flow is got over
Small, therefore, the difference of the Lift of valve body 7 can control the change of fluid flow size.When valve valve work when, fluid by
Enter under suction function from 8 bottom suction inlet 12 of valve seat and push valve body 7 open unlatching upwards, fluid enters in upper sap cavity, upper sap cavity
By reaction pressure force valve body 7 wink speed glide close, at this time the bottom end spherical surface (i.e. working face) of valve body 7 under pressure duty with
Valve rubber 10 forms buffering and sealing, and forms linear contact support with the inner cone disc of valve seat 8, to form unidirectional blocking
Valve, and can repeated work in cycles；Upper sap cavity is higher by reaction pressure, and the leakproofness of valve body 7 is better.
It can be seen that the valve valve of the utility model, structure is simple, and dismounting is flexible and convenient, and performance safety is reliable, manufacture at
This low, long service life can effectively solve the problem that traditional valve valve service life in oil drilling fracturing work is short, purchase cost
The problems such as height, inconvenient installation, practicability is extremely strong.
It should be noted that it is obvious to a person skilled in the art that the utility model is not limited to above-mentioned demonstration in fact
The details of example is applied, and without departing substantially from the spirit or essential attributes of the utility model, it can be with other specific shapes
