Description
Technical Field
The utility model relates to a reciprocating pump valve assembly technical field, in particular to adopt valve assembly of exempting from rubber valve body.
Background
The valve assembly is mainly used for generating high pressure through reciprocating work of a plunger or a piston, sucking the sand mixing fluid, sealing the pressure, and then conveying the sand mixing fluid to be injected into the underground. In a traditional valve assembly, rubber is fixed on a valve body and sleeved in a ring groove of the valve body, as shown in fig. 6, an inner hole of the rubber is in interference fit with the ring groove of the valve body to realize firm installation and is matched with a valve seat for use. The original valve body needs to be processed with the clamping groove because the rubber is considered to be installed, the processing is inconvenient, the overall strength of the valve body is reduced, and the service life is shortened.
During the use, the liquid can upwards be cyclic annular impact cutting valve body assembly by the feed liquor end, under long-term circumstances, the impact can lead to the rubber deformation on the valve body, and mud strikes and squeezes into and damages the rubber easily, the valve body also can cause rubber deformation or damage fast with the seal pressure of disk seat, need the change rubber of regularity, valve body metal surface exposes easily under the condition of rubber deformation, thereby it leads to the premature damage of disk seat and valve body directly to lead to the striking of metal covering with the disk seat, above problem is more obvious under the highly compressed condition of deep well.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a valve assembly of rubber valve body is exempted from in adoption is provided, the utility model discloses a rubber and disk seat formula structure as an organic whole is vulcanized, has cancelled traditional installation rubber structure, adopts streamlined S-shaped structure in the shape design, has avoided the stress concentration because of thermal treatment produces, has still increased the thickness and the intensity of stress point to valve body and disk seat metal collision damage that cause after avoiding the rubber to damage has prolonged the life of valve assembly by a wide margin.
The utility model solves the problems that the technical scheme adopted is that: including valve body, rubber and disk seat formula structure as an organic whole that vulcanizes, the disk seat upper end be equipped with rubber assorted draw-in groove, but the valve body suit just contacts with the rubber in the disk seat.
Furthermore, the valve seat is of a penetrating annular structure, and the rubber part at the upper end of the valve seat and the contact part of the valve body are of a spherical or conical working surface structure.
Furthermore, the excircle lower extreme of disk seat is equipped with the seal groove, is equipped with the sealing washer in the seal groove.
Furthermore, the sealing ring is an O-shaped sealing ring.
Furthermore, the thickness of the rubber on the valve seat is between 3mm and 7 mm.
Furthermore, the rubber adopts polyurethane or rubber as a raw material.
Furthermore, one end of the rubber sheet extends to the outer surface of the upper part of the valve seat, and the other end of the rubber sheet extends into the clamping groove in the upper surface of the valve seat.
The utility model has the advantages that: the rubber-free valve body reduces the diameter of the excircle of the valve body, lightens the weight of the valve body and reduces the impact accelerating force; adopt disk seat and rubber formula structure as an organic whole of vulcanizing, avoided prior art valve body assembly to strike the damage of bringing up silt to the rubber because of rubber deformation that leads to the fact and liquid impact because of high-pressure liquid, reduced the condition of damaging the disk seat because of rubber deformation, the valve body is spherical or toper working face structure with the contact site of rubber, the sphere transition can reduce stress, the structure of disk seat and rubber formula as an organic whole is more convenient and the valve body separation is better when sealed, and the valve body processing after just improving is easier, and intensity is higher, the utility model discloses life has been increased by a wide margin.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-5: the utility model provides an adopt valve assembly who exempts from rubber valve body, includes valve body 1, rubber 2 and disk seat 3 formula structure as an organic whole that vulcanizes, 3 upper ends of disk seat be equipped with rubber assorted draw-in groove 31, but 1 suit of valve body contact in disk seat 3 and with rubber 2.
The rubber is not easy to damage due to the design, the valve body is more convenient to process due to the fact that a rubber mounting clamping groove is not needed, strength is better, the diameter of the outer circle of the valve body is reduced due to the fact that the valve body is free of the rubber, weight of the valve body is reduced, impact accelerating force is reduced, and the service life of the valve assembly is prolonged.
The valve seat 3 is of a penetrating annular structure, and the contact part of the rubber sheet 2 at the upper end of the valve seat 3 and the valve body 1 is of a spherical or conical working surface structure; spherical or conical working surface transitions can reduce stress.
The excircle lower extreme of disk seat 3 is equipped with seal groove 4, is equipped with sealing washer 5 in the seal groove 4.
The sealing ring 5 is an O-shaped sealing ring which has the characteristics of simple installation, good sealing property, small movement friction resistance and the like.
The thickness of the rubber 2 on the valve seat 3 is 3 mm-7 mm, so that the service time of the rubber 2 is prolonged.
The rubber 2 is preferably made of polyurethane, and the polyurethane rubber has excellent physical properties, does not age after long-term use, and has good tear resistance, good resilience, good wear resistance and the like.
2 one end of rubber extends to surface 22 on disk seat upper portion, and in the other end extended to the draw-in groove 31 of disk seat upper surface, set up the draw-in groove and can prevent that the rubber from causing rubber and valve body not hard up to drop when receiving valve body striking extrusion, can improve the stability of vulcanizing integrative disk seat and using.
Specifically, as shown in fig. 6, in the prior art, the rubber is fixed on the valve body, and during operation, when the valve body is sealed with the valve seat assembly, the rubber is subjected to an upward high-pressure liquid impact force, and simultaneously, the rubber is in surface contact with the valve seat and is subjected to an impact force, so that the rubber is easily deformed, and thus, the metal part of the valve body is easily damaged too early due to impact with the valve seat; the rubber after the improvement is fixed on the valve seat, and during the work, the damage factors such as the premature damage of the rubber caused by the impact of upward high-pressure liquid on the original valve body assembly are avoided, only the collision friction between the valve body and the rubber on the valve seat exists, the damage condition is reduced, and the service life of the valve seat assembly is greatly prolonged. In traditional valve assembly work, before disk seat assembly life ended, need change 2 ~ 3 times valve body assembly usually, and after improving only need a valve body cooperation disk seat can, the bulk strength increase of valve body and processing are more convenient, the utility model discloses prolonged rubber, valve body and even the life of valve assembly greatly, practiced thrift the cost for the user.
The utility model discloses a rubber and disk seat have solved rubber deformation and the fragile problem of rubber for the integral type structure of vulcanizing, very big increase the rubber and even the life of valve assembly.
The foregoing shows and describes the basic principles, essential features, and advantages of the invention. The present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only for illustrating the principle of the present invention, and the present invention will have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements all fall into the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
