Description

Technical Field

[0001] This utility model relates to the field of gate valve technology in the petroleum industry, specifically a gate valve for the petroleum industry with a wear-resistant and reinforced structure. Background Technology

[0002] Petroleum industry gate valves with wear-resistant and reinforced structures resist wear and corrosion by using special materials and optimized structures. Their main function is to control the opening and closing of fluids. These valves are mainly composed of key components such as valve body, valve cover, valve stem and gate. The gate acts as the opening and closing element, and its movement direction is perpendicular to the fluid flow direction. In the oil and gas industry, petroleum industry gate valves play a vital role and are one of the important devices to ensure the safe operation of the system.

[0003] After oil transportation tasks are completed, fluid and impurities often remain on the surface of the gate valve for a long time. These residues are difficult to remove, and long-term accumulation will cause wear and corrosion to the gate valve's protective layer. Currently, manual disassembly is usually used for cleaning and maintenance, but this method is difficult to use. Therefore, a gate valve for the oil industry with a wear-resistant and reinforced structure is proposed to address the above problems. Utility Model Content

Long-term accumulation will cause wear and corrosion of the gate's protective layer. The cleaning and maintenance are usually carried out by manual disassembly, which is difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A petroleum industry gate valve with a wear-resistant reinforced structure includes a valve body, with delivery pipes welded to both sides of the valve body. A blocking assembly is provided on the inner side of the valve body. A support rod is fixedly connected to the top of the valve body, and an electric cylinder is fixedly connected to the top of the support rod via a mounting base. The blocking assembly includes a sealing ring, which is fixedly bonded to the inner side of the valve body. A gate plate is embedded inside the sealing ring. A water cavity is formed at the top of the inner side of the valve body. Mounting grooves are formed on both sides of the bottom of the water cavity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A petroleum industry gate valve with a wear-resistant and reinforced structure includes a valve body 1, with delivery pipes 2 welded to both sides of the valve body 1. A blocking assembly 3 is provided on the inner side of the valve body 1. A support rod 4 is fixedly connected to the top of the valve body 1. An electric cylinder 5 is fixedly connected to the top of the support rod 4 via a mounting base 6. The telescopic end of the electric cylinder 5 is fixedly connected to the middle of the top of the gate plate 32. The blocking assembly 3 includes a sealing ring 31, which is fixedly bonded to the inner side of the valve body 1 and is used to seal the connection of the gate plate 32. The gate plate 32 is embedded inside the sealing ring 31. A water cavity 33 is opened at the top of the inner side of the valve body 1. Mounting grooves 34 are opened on both sides of the bottom end of the water cavity 33. A protective mechanism 35 is fixedly connected inside the mounting grooves 34. A filter screen 36 is fixedly connected to the middle of the inner side of the delivery pipe 2. A first water injection pipe 37 is fixedly connected to the top of the delivery pipe 2. A filter screen 36 is fixedly connected to one side of the first water injection pipe 37. The second water injection pipe 38 and the middle of the bottom end of the delivery pipe 2 are fixedly connected to the drain pipe 39; the protective mechanism 35 includes a protective box 351, a connecting rod 352 is rotatably connected to one side of the bottom end of the protective box 351, and the rotation radius of the connecting rod 352 is 30°. A metal plate 353 is fixedly connected to the outside of the connecting rod 352, and a sealing strip 354 is fixedly connected to the side of the metal plate 353. A limit rod 355 is fixedly connected to the other side of the bottom end of the protective box 351. The limit rod 355 is made of strong magnetic material. The limit rod 355 and the metal plate 353 are magnetically attracted. Under natural conditions, the metal plate 353 is in a closed state, which can prevent impurities from entering the water cavity 33 during oil transportation. When cleaning is carried out, water flows into the water cavity 33 through the second water injection pipe 38. Under the impact of the water flow, the limit rod 355 can rotate downward. When the water flow stops, the limit rod 355 can attract the metal plate 353 and close.

[0028] As a further implementation of this solution, four support rods 4 are provided. The bottom ends of the four support rods 4 are located at the four corners of the top of the valve body 1, and the top ends of the four support rods 4 are fixedly connected to the four corners of the bottom of the mounting base 6, which improves stability and prevents shaking or tilting during use.

[0029] As a further implementation of this solution, the cross-sectional shape of the water cavity 33 is rectangular, the top of the protective box 351 is flush with the bottom of the inner side of the water cavity 33, and the outer surface of the protective box 351 is attached to the outer side of the gate 32. The protective box 351 can be used to scrape off the surface of the gate 32.

[0030] As a further implementation of this solution, the filter screen 36 is circular in shape, and the outer side of the filter screen 36 is in contact with the inner side of the conveying pipe 2. The filter screen 36 is located at the middle of the top of the drain pipe 39. The drain pipe 39 is U-shaped, and the inner side of the drain pipe 39 is connected to the inner side of the conveying pipe 2. A sealing pipe 391 is fixedly connected to the middle of the bottom end of the drain pipe 39. A sealing plug is threaded to the bottom end of the sealing pipe 391. The drain pipe 391 can be drained by opening the sealing plug.

[0031] As a further implementation of this solution, the angle between the first water injection pipe 37 and the second water injection pipe 38 is 90°. The bottom end of the first water injection pipe 37 is located in front of the filter screen 36. One end of the second water injection pipe 38 is fixedly connected to the top of the valve housing 1. The inner side of the second water injection pipe 38 is connected to the inner side of the water chamber 33. A portion of the water entering the first water injection pipe 37 flows to the water chamber 33 through the second water injection pipe 38, while the other portion of the water entering the first water injection pipe 37 flows into the bottom end of the first water injection pipe 37, thereby improving cleaning efficiency.

[0032] Workflow: Electric cylinder 5 is powered by an external power source. The telescopic end of electric cylinder 5 drives the gate 32 connected to it to move synchronously. During this process, support rod 4 ensures the stability of electric cylinder 5. By controlling the raising and lowering of gate 32, the gate 32 is opened and closed. Before entering valve body 1, oil first passes through filter screen 36 in delivery pipe 2 to filter larger particles, which reduces the adhesion of large particles to the surface of gate 32. Fine impurities and residues will still adhere to gate 32. After the oil delivery task is completed, in order to quickly clean fine impurities and residues, the top of the first water injection pipe 37 can be connected to an external high-pressure water pipe. A portion of the water entering the first water injection pipe 37 goes to water chamber 33 through second water injection pipe 38. The water entering water chamber 33 can not only clean the inside of valve body 1, but also... Water in the water chamber 33 can also be discharged through the protective mechanisms 35 on both sides of the bottom. Specifically, water pressure presses the magnetically connected metal plate 353, causing the metal plate 353 to rotate downward around the connecting rod 352, thus opening the metal plate 353. Water flows out through the gap between the metal plate 353 and the limiting rod 355, cleaning the residues attached to both sides of the gate plate 32. Another part of the water entering the first water injection pipe 37 will flow into the bottom of the first water injection pipe 37 to wash the debris and impurities attached to the surface of the filter screen 36 below, ensuring normal use later. The water flow can simultaneously wash the filter screen 36, the inside of the valve body 1, and the gate plate 32. Finally, the cleaned dirt will flow into the sealing pipe 391 through the drain pipe 39 and open the sealing plug of the sealing pipe 391 to discharge the dirt from the inside of the valve body 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
