Description

Technical Field

[0001] This utility model relates to the field of eccentric hemispherical valve technology, specifically an eccentric hemispherical valve that isolates metal materials. Background Technology

[0002] Eccentric ball valves are commonly used in pipelines transporting liquids or gases. Their primary function is to cut off, distribute, and change the flow velocity and direction of the medium within the pipeline. The closing element of an eccentric ball valve is a hemispherical valve disc, which is rotated to open or close the valve.

[0003] Valves are essential products for pipeline transportation lines. However, many materials cannot come into contact with metal during transportation, such as certain chemicals. Once they come into contact with metal, they may cause chemical reactions, affecting product quality and even causing safety accidents. Traditional eccentric hemispherical valves are mainly made of metal materials and cannot meet these special requirements. Therefore, an eccentric hemispherical valve that isolates metal materials is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an eccentric hemispherical valve that isolates metal materials, so as to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an eccentric hemispherical valve for isolating metal materials, comprising a valve body, a valve core installed at the center inside the valve body, and a removal assembly provided on one side of the valve body. A sealing ring is snapped onto one side of the inner wall of the valve body, and a pressure ring abuts against the side of the sealing ring away from the valve core. The pressure ring is threadedly connected to the valve body. A square shaft is snapped onto the top of the valve core, and the end of the square shaft passes through the top of the valve body. A round shaft is rotatably connected to the bottom of the valve core. The inner wall of the valve body, the valve core, the sealing ring, and the inner wall of the pressure ring are all coated with a polyurethane adhesive layer.

[0006] As a preferred technical solution, one side of the pressure ring abuts against the sealing ring, and a sealing ring is provided at the contact point between the pressure ring and the sealing ring.

[0007] As a preferred technical solution, the dismantling component includes a long rod that is slidably connected to both sides inside the pressure ring, and a horizontal plate is fixed to one end of the long rod.

[0008] As a preferred technical solution, one end of the long rod passes through one side of the pressure ring and extends into the inside of the sealing ring, and a slot for the horizontal plate to rotate is provided inside the sealing ring.

[0009] As a preferred technical solution, the pressure ring has two sets of grooves on the side away from the sealing ring, and a vertical plate is provided in the groove. A base rod that is rotatably connected to the pressure ring is provided on one side of the vertical plate, and a buckle groove is provided at the front end of the vertical plate.

[0010] As a preferred technical solution, the end of the long rod away from the horizontal plate is fixed with a rotating shaft, and the rotating shaft and the vertical plate are on the same horizontal plane as the pressure ring.

[0011] In summary, the present invention has the following main advantages:

[0012] 1. This utility model utilizes a polyurethane adhesive layer to coat key components, which not only enhances the valve's corrosion resistance and wear resistance but also effectively isolates the metal materials from direct contact with the fluid medium, thereby significantly improving the valve's overall performance and durability. As a high-performance material, the polyurethane adhesive layer possesses excellent elasticity and sealing properties, allowing it to tightly adhere to the inner walls of the valve body, valve core, sealing ring, and pressure ring, effectively preventing fluid medium leakage and ensuring the valve's stability and reliability during operation. Furthermore, the polyurethane adhesive layer exhibits good anti-aging properties, maintaining its excellent physical and chemical properties for a long period, further extending the valve's service life.

[0013] 2. This utility model allows for the simultaneous removal of the sealing ring from the valve body by loosening the threaded connection between the pressure ring and the valve body and removing it from the valve body, using a long rod and a horizontal plate. The operation is simple and convenient, greatly improving disassembly efficiency and reducing maintenance costs. In this process, no complicated tools or equipment are required, significantly saving time and labor costs. Furthermore, by setting up the disassembly component, when maintenance or replacement of the sealing ring is required, it is not necessary to disassemble the entire valve; only the pressure ring needs to be removed, effectively protecting the integrity of the valve body and avoiding valve body damage caused by frequent disassembly.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] An eccentric hemispherical valve that isolates metal materials, such as Figure 1-5 As shown, the valve body includes a valve body 100, a valve core 110 is installed at the center inside the valve body 100, and a removal assembly 200 is provided on one side of the valve body 100. A sealing ring 120 is snapped into one side of the inner wall of the valve body 100. A pressure ring 130 abuts against the side of the sealing ring 120 away from the valve core 110. The pressure ring 130 is threadedly connected to the valve body 100. A square shaft 150 is snapped into the top of the valve core 110. The end of the square shaft 150 passes through the top of the valve body 100. A round shaft 160 is rotatably connected to the bottom of the valve core 110. The inner wall of the valve body 100, the valve core 110, the sealing ring 120, and the inner wall of the pressure ring 130 are all coated with a polyurethane adhesive layer 170.

[0024] It is worth noting that the polyurethane adhesive layer 170 on the inner wall of valve body 100, valve core 110, sealing ring 120 and pressure ring 130 is coated with a mold. After coating, the edges are trimmed, deburred and cleaned. Then the components are assembled and tested with 0.7 MPa air pressure and held for 2 hours to ensure the sealing of valve body 100.

[0025] When materials are transported inside the pipeline, the valve core 110 is rotated inside the valve body 100 by rotating the square shaft 150, thereby controlling the flow rate of the materials being transported. By using an eccentric hemispherical valve core 110, friction can be effectively reduced and the operating torque can be lowered, making it easier to operate. At the same time, a polyurethane adhesive layer 170 is used to coat the valve body 100, valve core 110, sealing ring 120, and pressure ring 130, which improves the overall corrosion resistance and wear resistance, thereby extending the service life of the valve body 100. The polyurethane adhesive layer 170 can also effectively isolate metal materials from direct contact with the fluid medium, preventing valve leakage caused by medium corrosion and better ensuring the durability of the product. In addition, the design of the removal component 200 makes it easy to quickly remove the pressure ring 130 when maintenance or replacement of the sealing ring 120 is required, improving the maintainability of the valve.

[0026] Please refer to this carefully. Figure 1and Figure 2 The pressure ring 130 abuts against the sealing ring 120 on one side, and a sealing ring 140 is provided at the contact point between the pressure ring 130 and the sealing ring 120.

[0027] The overall sealing performance is improved, ensuring the stability and reliability of the valve during operation. The sealing ring 140 is preferably made of rubber or silicone, which has good elasticity and wear resistance, further enhancing the sealing effect and preventing fluid leakage.

[0028] Please refer to this carefully. Figures 3 to 5 The removal assembly 200 includes a long rod 210 slidably connected to both sides inside the pressure ring 130. One end of the long rod 210 is fixed with a horizontal plate 220. The other end of the long rod 210 passes through one side of the pressure ring 130 and extends into the interior of the sealing ring 120. The sealing ring 120 has a slot 230 for the horizontal plate 220 to rotate. The side of the pressure ring 130 away from the sealing ring 120 has two sets of grooves 251. The grooves 251 have vertical plates 250. One side of the vertical plate 250 has a base rod that is rotatably connected to the pressure ring 130. The front end of the vertical plate 250 has a buckle groove 252.

[0029] When the sealing ring 120 needs to be removed, the vertical plate 250 rotates out through the base rod by pulling the retaining groove 252. Twisting the rotating shaft 240 causes the long rod 210 to rotate, which in turn causes the horizontal plate 220 to rotate within the retaining groove 230 until the horizontal plate 220 and the retaining groove 230 are locked in place. Then, rotating the vertical plate 250 causes the pressure ring 130 to rotate synchronously, loosening the threaded connection between the pressure ring 130 and the valve body 100. Simultaneously, the pressure ring 130 moves out of the valve body 100, and the long rod 210... The sealing ring 120 can be removed from the valve body 100 simultaneously with the horizontal plate 220. The operation is simple and convenient, which greatly improves the disassembly efficiency and reduces the maintenance cost. In this process, no complicated tools or equipment are required, which saves a lot of time and labor costs. In addition, by setting the disassembly component 200, when it is necessary to maintain or replace the sealing ring 120, it is not necessary to disassemble the entire valve. Only the pressure ring 130 needs to be removed, which effectively protects the integrity of the valve body 100 and avoids the problem of valve body 100 being damaged due to frequent disassembly.

[0030] Please refer to this carefully. Figure 5 The end of the long rod 210 away from the horizontal plate 220 is fixed with a rotating shaft 240. The rotating shaft 240 and the vertical plate 250 are both on the same horizontal plane as the pressure ring 130.

[0031] By setting the rotating shaft 240, the vertical plate 250 and the pressure ring 130 to the same horizontal plane, it is convenient to connect the valve body 100 to the external pipeline.

[0032] In use, rotating the square shaft 150 drives the valve core 110 to rotate inside the valve body 100, thereby controlling the flow rate when conveying materials. By using an eccentric hemispherical valve core 110, friction can be effectively reduced, and the operating torque can be lowered, making operation more convenient. The valve body 100, valve core 110, sealing ring 120, and pressure ring 130 are coated with a polyurethane adhesive layer 170, which improves the overall corrosion resistance and wear resistance, thereby extending the service life of the valve body 100. The polyurethane adhesive layer 170 can also effectively isolate metal materials from direct contact with the fluid medium, preventing valve leakage caused by medium corrosion and better ensuring the durability of the product. In addition, the design of the disassembly component 200 facilitates the quick disassembly of the pressure ring 130 when maintenance or replacement of the sealing ring 120 is required, improving the maintainability of the valve. All parts not mentioned in this device are the same as or can be implemented using existing technologies.
