Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve rubbers, in particular to a valve rubber for a valve box with reduced wear. Background Art
[0002] In order to ensure that liquid or gas can flow in the predetermined direction and prevent backflow, a one-way valve is usually used; it ensures that the fluid can only flow in one direction, and is therefore indispensable in many industries, especially in high-pressure operating environments such as drilling, cementing, and fracturing in the oil and gas industry, where the one-way valve is a key safety and efficiency assurance component; and a key component to ensure the operation of the one-way valve is the valve core of the one-way valve, which is usually designed as a small component that can move freely and controls the one-way flow of the fluid through its movement; in order to enable the valve core to open or close quickly with changes in the pressure of the fluid, while ensuring the sealing performance of the valve core when closed and preventing fluid leakage, a valve is usually installed on the outside of the valve core.
[0003] However, in the prior art, the valve rubber usually has a smooth surface that is in direct contact with the fluid. Especially when working in a high-pressure environment, the valve rubber is easily affected by the fluid pressure, resulting in uneven pressure distribution on the surface of the valve rubber, causing excessive local pressure, thereby leading to uneven contact pressure between the valve rubber and the valve seat, causing increased wear, and greatly reducing the service life of the valve rubber, thereby affecting the overall performance of the one-way valve.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
[0005] In response to the problems in the related art, the utility model proposes a valve box rubber with reduced wear to overcome the above-mentioned technical problems existing in the existing related art.
[0006] To this end, the specific technical solutions adopted in this utility model are as follows:
[0007] A valve box for reducing wear is provided with a valve rubber sleeve, which is arranged on the outer side of the circumference of a valve core and includes a rubber body installed on the outer side of the valve core. Anti-wear components are symmetrically arranged on the outer side of the rubber body. The top end of a group of anti-wear components located above and the bottom end of a group of anti-wear components located below are both provided with pressure dispersion components. The cross-section of the rubber body is a hollow annular structure, a dividing line is provided in the middle of the rubber body, and the diameters of both sides of the rubber body gradually decrease in the direction away from the dividing line, so that the rubber body forms a flat end face.
[0008] Furthermore, in order to reduce the wear of the valve rubber, the wear surface of the valve rubber can be increased by evenly distributing a number of hemispherical structured protrusions, which helps to disperse the wear force and prevent excessive wear in a certain area, thereby extending the service life of the valve rubber and improving the durability of the rubber. The anti-wear component includes a number of protrusions arranged on the outside of the rubber body; the protrusions are hemispherical structures, and the several protrusions are evenly arranged and distributed in a circular shape on the outside of the rubber body.
[0009] Furthermore, in order to avoid premature wear caused by uneven force on the surface of the rubber body, the contact area between the surface of the rubber body and the fluid can be increased under the action of a plurality of linearly distributed annular bands, and at the same time, the impact force of the fluid can be further dispersed under the action of a plurality of circumferentially distributed through holes, thereby dispersing the pressure on the surface of the rubber body, preventing the formation of local high pressure, and avoiding the wear of the rubber body caused by uneven force. Moreover, under the buffering effect of the guide belt on the fluid, the pressure of the fluid can be more evenly dispersed, wear can be reduced, and the service life of the valve rubber can be extended. The pressure dispersion component includes a plurality of annular bands arranged on the outside of the rubber body, a plurality of through holes are opened at the top of the annular bands, and a guide band is arranged on the outside of the annular bands; the plurality of annular bands are evenly arranged and linearly distributed on the outside of the rubber body, and the diameter of the annular bands gradually decreases in the direction away from the dividing line; the plurality of through holes are evenly arranged and circumferentially distributed at the top of the annular bands.
[0010] The beneficial effects of the utility model are:
[0011] 1. The utility model coordinates the valve core, the rubber body, the anti-wear component and the pressure dispersion component, which not only enables the valve core to open or close quickly as the pressure of the fluid changes, but also ensures the sealing performance of the valve box when the valve core is closed to prevent fluid leakage, and can avoid excessive local pressure on the surface of the valve rubber due to uneven pressure distribution of the fluid, reduce the wear of the valve rubber, greatly increase the service life of the valve rubber, and thus improve the overall performance of the one-way valve.
[0012] 2. Through the anti-wear components, the wear surface of the valve rubber can be increased under the action of several evenly distributed hemispherical structural bumps, which helps to disperse the wear force and prevent excessive wear in a certain area, thereby extending the service life of the valve rubber and improving the durability of the rubber.
[0013] 3. Through the pressure dispersion component, the contact area between the rubber body surface and the fluid can be increased under the action of the linear distribution of several annular belts. At the same time, under the action of the circumferential distribution of several through holes, the impact force of the fluid can be further dispersed, the pressure on the surface of the rubber body is dispersed, the formation of local high pressure is prevented, and the wear of the rubber body due to uneven force is avoided. Under the buffering effect of the guide belt on the fluid, the pressure of the fluid can be more evenly dispersed, wear is reduced, and the service life of the valve rubber is extended.
