Abstract
A novel ball body structure of a high-pressure ball valve comprises a valve body, a valve seat and a ball body. Wear to be equipped with entrance point, exit end in the valve body, the valve body inner chamber is equipped with the disk seat of bisymmetry, and the disk seat of bisymmetry inlays respectively to be adorned in valve body entrance point right side, valve body exit end left side, be equipped with the spheroid between the disk seat of bisymmetry, be equipped with the spheroid runner in the spheroid, the spheroid is equipped with the pressure release hole with the sealing region outside of disk seat, and the pressure release hole is the cylinder through-hole, and the pressure release hole specifically is two, and two pressure release holes specifically are located spheroidal upper left corner and lower right corner, and pressure release hole one end communicates in with the. The utility model has the advantages that: when the ball valve is gradually opened from the fully closed state of the ball body, the pressure relief hole can cross the valve seat sealing surface to generate pressure relief in advance when the valve seat sealing surface does not reach the thinner and thinner ball opening, so that the risk of deformation of the ball opening caused by high pressure of the ball body is avoided, and the ball body is protected.
Description
Technical Field
The utility model relates to a spheroid of high-pressure ball valve, especially a novel spheroid structure of high-pressure ball valve.
Background
As is well known, the most critical component of a ball valve is a ball body, if the ball body deforms due to the pressure of fluid, then a valve leaks, particularly, the ball body of a high-pressure ball valve, the pressure-bearing wall thickness of the ball body of the ball valve becomes thinner and thinner in the process from the completely closed state of the ball valve to the gradual opening of the valve, which is determined by the characteristics of the ball body, when a valve seat sealing ring reaches a ball opening and does not separate from the ball opening, the valve is still in a sealed state, and in this time, the ball opening of the high-pressure valve is easily deformed due to the thinner and thinner wall thickness, so that the sealing leakage of the valve due to the deformation of the ball body is caused. Therefore, it is urgently needed to design a novel sphere structure to solve the problem that the sphere structure is easy to generate deformation of the sphere opening under a high-pressure opening state.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a novel ball structure of a high-pressure ball valve, which comprises a valve body, a valve seat and a ball body.
The utility model provides a technical scheme that prior art problem adopted is: wear to be equipped with entrance point, exit end in the valve body, the direction that the arrow point instructed in the drawing is the exit end, and the valve body inner chamber is equipped with the disk seat of bisymmetry, and the disk seat of bisymmetry inlays respectively and inlays the dress in valve body entrance point right side, valve body exit end left side, be equipped with the spheroid between the disk seat of bisymmetry, be equipped with the spheroid runner in the spheroid, and the spheroid is equipped with the pressure release hole with the sealed region outside of disk seat, and the pressure release hole is the cylinder through-hole, and the pressure release hole specifically is two, and two pressure release holes specifically are located spheroidal upper left corner and lower right corner, communicate in pressure release hole one end and the valve body, and the pressure release hole other end is linked together.
The utility model has the advantages that: when the ball valve is gradually opened from the fully closed state of the ball body, the pressure relief hole can cross the valve seat sealing surface to generate pressure relief in advance when the valve seat sealing surface does not reach the thinner and thinner ball opening, so that the risk of deformation of the ball opening caused by high pressure of the ball body is avoided, and the ball body is protected.

Detailed Description
In the description of the present invention, it should be noted that the terms "left end", "right end", "upper left corner", "lower right corner", "one end", "the other end" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The present invention will be described in further detail with reference to the accompanying drawings and embodiments, a novel ball structure of a high-pressure ball valve comprises a valve body 1, a valve seat 2, and a ball body 3, wherein an inlet end 101 and an outlet end 102 are arranged in the valve body 1, the direction indicated by the arrow in the drawings is the outlet end 102, the inner cavity of the valve body 1 is provided with two symmetrical valve seats 2, the two symmetrical valve seats 2 are respectively embedded in the right side of the inlet end 101 of the valve body 1 and the left side of the outlet end 102 of the valve body 1, the ball body 3 is arranged between the two symmetrical valve seats 2, a ball body flow passage 301 is arranged in the ball body 3, a pressure relief hole 4 is arranged outside the sealing area between the ball body 3 and the valve seat 2, the pressure relief hole 4 is a cylindrical through hole, the pressure relief holes 4 are specifically two, the two pressure relief holes 4 are specifically positioned in the upper left corner and the lower right corner of, when the sealing is normal, the pressure relief hole 4 is positioned outside the sealing area of the ball body and the valve seat, and the sealing between the valve seat 1 and the ball body 3 is not influenced; when the ball valve is opened gradually from the fully closed state of the ball body 3, the pressure relief hole 4 can cross the sealing surface of the valve seat 2 to generate pressure relief in advance when the sealing surface of the valve seat 2 does not reach the thinner ball opening, so that the risk of deformation of the ball opening caused by high pressure of the ball body 3 is avoided, and the ball body 3 is protected.
The utility model discloses a set up pressure release hole 4 in spheroid 3 and the sealed regional outside of disk seat 2, from the state that spheroid 3 closed completely to the in-process of opening gradually as the ball valve, pressure release hole 4 can just cross the sealed face of disk seat 2 and produce the pressure release in advance when the sealed face of disk seat 2 has not yet arrived more and more thin ball mouth to the risk of spheroid 3 because high pressure causes the ball mouth to warp has been avoided, spheroid 3 has been protected.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
