Valve body

Abstract

The utility model discloses a valve body which comprises a valve body. The valve body is provided with a mounting groove for mounting the sealing ring; the face, facing the sealing ring, of the installation groove is provided with an inclined face. On the basis, due to the arrangement of the inclined surface, the sealing ring is in inclined surface contact with the inclined surface, so that when the valve body moves, an angle is formed between the sealing ring and the inclined surface, and the sealing ring can be automatically reset under the angle, so that the rebound coefficient under high-pressure impact is increased.

Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pump accessories, in particular to a valve body. Background Art

[0002] like Figure 1 and Figure 2 As shown, the installation groove on the existing valve body does not have an inclined surface, that is, the facing surfaces of the valve body and the sealing ring are in planar contact. In order to improve the stability of the sealing ring after installation, a corresponding groove needs to be opened on the plane to enhance the stability of the sealing ring after installation.

[0003] From this we can see that the valve body must first be machined with a notch, and the sealing ring must be machined with a pin corresponding to the notch, in order to complete a reliable connection between the sealing ring and the valve body. Utility Model Content

[0004] The purpose of the present utility model is to provide a valve body to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a valve body, comprising a valve body; a mounting groove for mounting a sealing ring is provided on the valve body, and a side of the mounting groove facing the sealing ring has an inclined surface.

[0006] As a preferred technical solution of the present invention: a vertical central axis is built in the installation groove; wherein the angle between the inclined surface and the central axis is a, and 0°<a<3°.

[0007] As a preferred technical solution of the present utility model: the angle a between the inclined surface and the central axis is 2°.

[0008] By adopting the above technical solution, the beneficial effects of the utility model are as follows: 1. Due to the arrangement of the inclined surface, when the sealing ring is pressurized, it can shrink inward along the inclined surface, and when the pressure disappears, the sealing ring can slide outward along the inclined surface. Therefore, while ensuring the stable position of the sealing ring during use, it can also reduce the difficulty of processing the valve body and the sealing ring;

[0009] 2. Due to the setting of the inclined surface, the sealing ring and the inclined surface are in inclined contact. Therefore, when the valve body moves, there is an angle between the sealing ring and the inclined surface. At this angle, the sealing ring can automatically reset to improve the rebound coefficient under high-pressure impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does 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 therefore cannot be construed as a limitation on the present invention.

[0016] See also Figure 3-4 The utility model provides an embodiment: a valve body, characterized in that: it includes a valve body 1; the valve body 1 is provided with a mounting groove 2 for mounting a sealing ring, and the mounting groove 2 has a slope 4 on a side facing the sealing ring.

[0017] In summary, due to the arrangement of the inclined surface 4, when the sealing ring is under pressure, it can shrink inward along the inclined surface 4, and when the pressure disappears, the sealing ring can slide outward along the inclined surface 4. Therefore, while ensuring the stable position of the sealing ring during use, it can also reduce the difficulty of processing the valve body and the sealing ring.

[0018] Furthermore, due to the setting of the inclined surface 4, the sealing ring and the inclined surface are in inclined contact, so when the valve body moves, there is an angle between the sealing ring and the inclined surface. At this angle, the sealing ring can automatically reset to improve the rebound coefficient under high-pressure impact.

[0019] Specifically, a vertical central axis 3 is built in the installation groove 2; wherein, the angle between the inclined surface 4 and the central axis 3 is a, and 0°<a<3°. Within this angle range, the service life and sealing performance of the sealing ring can be taken into account.

[0020] In particular, when the angle a between the inclined surface 4 and the central axis 3 is 2°, the working performance of the sealing ring is optimal.

[0021] To sum up, since the inclined surface 4 can position the sealing ring without affecting the sealing performance of the sealing ring, compared with the existing technology, there is no need to process grooves on the valve body and there is no need to process protrusions corresponding to the grooves on the sealing ring, which makes the optimized valve body structure simpler and the processing is more convenient and efficient; it is beneficial to improve the valve body processing efficiency and reduce the processing cost.

[0022] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
