Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves, in particular to a one-way valve assembly. Background Art

[0002] A one-way valve, also known as a non-return valve or check valve, is a valve used to control the one-way flow of fluid. It prevents the fluid from flowing in one direction while allowing free flow in the other direction. One-way valves are commonly used in hydraulic systems, air compressors, water pumps and other equipment to ensure that the fluid can only flow in one direction to prevent backflow or reverse flow. The working principle of a one-way valve is that through the design of the valve core or valve plate, the fluid can flow smoothly in one direction, while the flow in the other direction will be blocked or restricted.

[0003] In the early production pipe strings of many old wells, the installation range of the one-way valve was limited because the tools for arranging the one-way valve could only be used in reasonable positions to complete the installation of the one-way valve. Utility Model Content

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Please refer to Figure 1-Figure 3 The utility model provides a one-way valve assembly, including a main body 2, a screw plug 5 and a valve ball 6. The screw plug 5 is arranged in the main body 2, and the valve ball 6 is located in the screw plug 5. The valve ball 6 is a regular spherical structure. The main body 2 is a cylindrical structure as a whole, which is used to be installed in a pre-opened pipe wall hole. The main body 2 is preferably made of tool steel grade material, which is characterized by high hardness, wear resistance and erosion resistance, and can easily pierce softer metal materials.

[0022] The valve ball 6 is made of a corrosion-resistant alloy or hard alloy with high hardness, which is wear-resistant and erosion-resistant, and the screw plug 5 structure inside the main body 2 can achieve the function of flow or flow blocking in a specified direction. The chamfer at the contact point between the main body 2 and the valve ball 6 forms a valve seat.

[0023] A plurality of protrusions 1 are arranged on the outside of the main body 2 for fixing the main body 2 on the tube wall. The protrusion 1 is annular as a whole and arranged around the main body 2. A spike corner is arranged on the outside of the protrusion 1, that is, the cross section of the protrusion 1 is triangular, and one of the vertices of the triangle is used to pierce the tube wall to achieve the purpose of being embedded in the tube wall.

[0024] In this embodiment, the screw plug 5 includes a connecting block 8 and two fixing parts 9. The two fixing parts 9 are symmetrically arranged on both sides of the connecting block 8. The valve ball 6 is located between the two fixing parts 9. The width of the connecting block 8 is smaller than the width of the fixing parts 9. When the one-way valve is opened, the liquid can flow out from both sides of the connecting block 8.

[0025] Secondly, a flow hole is opened at one end of the main body 2 , a first threaded hole is opened at the lower part of the flow hole, and the screw plug 5 is threadedly connected to the main body 2 .

[0026] Specifically, when the liquid flows from the threaded hole to the flow hole, the valve ball 6 blocks the flow hole and the one-way valve is closed. Conversely, when the liquid flows from the flow hole to the threaded hole, the valve ball 6 moves downward and the one-way valve is opened.

[0027] In this embodiment, a connecting ring 4 is arranged around the bottom of the main body 2, a through hole is opened on the connecting ring 4, a fixed shear pin 3 is arranged in the through hole, and the fixed shear pin 3 is made of metal or copper alloy with specific mechanical properties. Its function is to fix the one-way valve assembly on the corresponding punching tool, and under specific conditions, it is required to be sheared to discard the one-way valve assembly.

[0028] Specifically, two groups of through holes and fixed shear pins 3 are respectively provided and symmetrically arranged on both sides of the connecting ring 4.

[0029] In addition, a second threaded hole 7 is provided in the middle of the connecting block 8, and a screw can be installed in the second threaded hole. The screw can fix the valve ball and form one of the important parts of the valve structure.

[0030] The structural feature of the utility model is that the main body made of a relatively hard material is used to pierce the relatively soft metal pipe wall, and the valve ball 6 and the screw plug 5 structure realize the one-way flow function of the fluid. The barb structure of the protruding part of the outer circle of the main body 2 is conducive to the one-way valve component piercing the metal pipe wall, and the one-way valve component is stuck by the slight rebound deformation of the pipe wall, thereby preventing the one-way valve component from falling off the pipe wall.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
