Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a drilling and oiling device for extending the service life of valves. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be classified into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] Currently, downhole extraction systems mainly use butterfly valves of models such as φ400, φ500, φ630, and φ800. During operation, each system requires continuous maintenance or system adjustment, which necessitates the closure or opening of certain valves. However, in actual work, we have found that the valves exhibit the following phenomena: (1) Increased valve opening and closing resistance, leading to screw twisting when applying force to close, preventing the valve from performing opening and closing actions; (2) Incomplete gate closure, resulting in internal leakage and inability to effectively cut off the pipeline; (3) Excessive force when unable to confirm closure directly causes cracking of the top cover, resulting in gas leakage. Therefore, we have proposed a drilling and oil injection device to extend the service life of valves and solve the above problems. Utility Model Content

[0018] like Figure 1 As shown, in some embodiments, the valve body 1 and the valve seat 2 are integrally formed.

[0019] In this embodiment, the structure between the valve body 1 and the valve seat 2 has high strength and is not easily broken or damaged.

[0020] like Figure 2 As shown, in some embodiments, the rotating mechanism 3 includes a bearing assembly 301, a valve cover 302, and a first fastening bolt 303. The bearing assembly 301 is fixedly installed in the inner wall of the left and right valve seats 2, and the left and right bearing assemblies 301 are fixedly installed with the valve stem 4. The valve cover 302 is installed on the side of the valve seat 2 away from the valve body 1 by the first fastening bolt 303.

[0021] In this embodiment, the left and right bearing assemblies 301 are equipped with the rotation function of the valve stem 4. The valve cover 302 is installed on the valve seat 2 by the first fastening bolt 303, so that the valve cover 302 limits and seals the bearing assembly 301.

[0022] like Figure 2As shown, in some embodiments, a first rubber sealing ring 8 is provided between the valve cover 302 and the valve seat 2.

[0023] In this embodiment, the first rubber sealing ring 8 improves the sealing effect between the valve cover 302 and the valve seat 2.

[0024] like Figure 2 As shown, in some embodiments, the sealing mechanism 5 includes a sealing packing 501, a second fastening bolt 502, and a pressure plate 503. The sealing packing 501 is installed on the valve body 1 at a position corresponding to the outer surface of the valve stem 4, and the pressure plate 503 is installed on the outer surface of the valve body 1 corresponding to the sealing packing 501 by means of the second fastening bolt 502.

[0025] In this embodiment, the sealing packing 501 increases the sealing performance between the valve stem 4 and the valve body 1, so that the second fastening bolt 502 installs the pressure plate 503 on the valve body 1, and the pressure plate 503 limits the sealing packing 501. The sealing packing 501 adopts commonly used components for sealing between the valve body 1 and the valve stem 4.

[0026] like Figure 2 As shown, in some embodiments, through holes 9 are provided on the pressure plate 503 and the valve cover 302 at positions corresponding to the valve stem 4.

[0027] In this embodiment, the through hole 9 satisfies the requirement for the valve stem 4 to rotate on the pressure plate 503 and the valve cover 302.

[0028] like Figure 3 As shown, in some embodiments, the liquid injection mechanism 7 includes a flow channel 701, a liquid outlet channel 702, a one-way liquid injection valve 703, and a filter screen sleeve 704. The flow channel 701 is provided on the right side of the valve stem 4.

[0030] like Figure 3 As shown, in some embodiments, a second rubber sealing ring 10 is installed between the left side of the one-way injection valve 703 and the right side of the flow channel 701.

[0031] In this embodiment, the second rubber sealing ring 10 improves the sealing effect between the one-way injection valve 703 and the valve stem 4, thus preventing leakage.

[0032] In use, external lubricant is connected to the one-way injection valve 703 in the injection mechanism 7 via an injection gun. The lubricating oil flows into the flow channel 701 through the one-way injection valve 703. The filter screen 704 filters impurities in the lubricating oil flowing into the flow channel 701. The lubricating oil in the flow channel 701 flows into the bearing assembly 301 in the rotating mechanism 3 in the left and right valve seats 2 through the left and right outlet channels 702. This increases the lubrication function of the bearing assembly 301, improves the rotation performance of the bearing assembly 301, prevents the bearing assembly 301 from being corroded and rusted, ensures the normal rotation of the valve stem 4, facilitates the maintenance of the valve, extends the service life of the valve, reduces the need for valve replacement, and reduces the cost of use.
