Description

Technical Field

[0001] This utility model relates to the field of fluoropolymer-lined gate valves, specifically a high-temperature and high-pressure wedge-type double-gate fluoropolymer-lined gate valve. Background Technology

[0002] A fluoropolymer-lined gate valve is a type of valve. The opening and closing element of a fluoropolymer-lined gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed, and cannot be used for regulation or throttling.

[0003] After long-term operation, the internal valve seat of a fluoropolymer-lined gate valve is prone to wear. Since the valve seat is usually fixed by inlay, due to long-term use, the valve seat and the groove are tightly engaged. Operators need to use special tools such as pry bars and pullers, which makes the whole replacement process time-consuming and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, where long-term use results in a tight fit between the valve seat and the groove, requiring operators to use specialized tools such as pry bars and pullers, leading to a time-consuming and labor-intensive replacement process, this invention proposes a high-temperature, high-pressure wedge-type double-gate fluoropolymer-lined gate valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high temperature and high pressure wedge double gate fluoropolymer-lined gate valve, including a fluoropolymer-lined gate valve body, the fluoropolymer-lined gate valve body including a valve body, a first adjusting screw sleeve fixedly connected to one side of the inner cavity of the valve body, a lead screw threadedly connected to the inner cavity of the first adjusting screw sleeve, a rotating wheel fixedly connected to one end of the first adjusting screw sleeve, the surface of the lead screw movably connected to the inner cavity of the rotating wheel, a gate plate fixedly connected to one end of the lead screw, the number of gate plates is two, a valve seat movably connected to one side of the gate plate, and the surface of the valve seat movably connected to the inner cavity of the valve body;

One side of the mounting block is fixedly connected to one side of the valve body, one side of the connecting block is fixedly connected to one side of the valve seat, and one side of the placement block is fixedly connected to the other side of the valve seat. There are two connecting blocks and two placement blocks. A rotating column is fixedly connected to the inner cavity of the mounting block. A rotating plate is movably connected to the surface of the rotating column. A threaded rod is movably connected to the inner cavity of the rotating plate. A second adjusting sleeve is threadedly connected to the surface of the threaded rod. One side of the second adjusting sleeve is movably connected to one side of the rotating plate. A rotating shaft is movably connected to one end of the threaded rod. Both ends of the rotating shaft are fixedly connected to fixed plates. One side of the fixed plate is fixedly connected to one side of the valve body. There are four fixed plates. A fixed column is fixedly connected to one side of the connecting block. There are four fixed columns.

[0007] Preferably, a fixing groove is provided on one side of the connecting block, and one side of the rotating plate is inserted into the inner cavity of the fixing groove.

[0008] Preferably, a movable groove is provided on one side of the rotating plate, and the surface of the threaded rod is movably connected to the inner cavity of the movable groove.

[0012] Preferably, one end of the threaded rod is fixedly connected to a limiting block, the diameter of which is larger than the diameter of the threaded rod.

[0013] The advantages of this utility model are:

[0014] This invention involves manually holding a fixed column to insert the valve seat into the placement groove. Then, pulling a rotating plate causes one side of the rotating plate to rotate around the surface of the rotating column, ensuring the rotating plate is fully inserted into the fixed groove and fixing the valve seat's position.

Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a high-temperature, high-pressure wedge-type double-gate fluoropolymer-lined gate valve. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-temperature and high-pressure wedge-type double-gate fluoropolymer-lined gate valve includes a fluoropolymer-lined gate valve body 1. The fluoropolymer-lined gate valve body 1 includes a valve body 101. A first adjusting screw sleeve 104 is fixedly connected to one side of the inner cavity of the valve body 101. A lead screw 103 is threadedly connected to the inner cavity of the first adjusting screw sleeve 104. A rotating wheel 102 is fixedly connected to one end of the first adjusting screw sleeve 104. The surface of the lead screw 103 is movably connected to the inner cavity of the rotating wheel 102. A gate plate 106 is fixedly connected to one end of the lead screw 103. There are two gate plates 106. A valve seat 105 is movably connected to one side of the gate plate 106. The surface of the valve seat 105 is movably connected to the inner cavity of the valve body 101.

[0026] A replacement mechanism 2 is provided on one side of the valve body 101. The replacement mechanism 2 includes a mounting block 201, a connecting block 205, and a placement block 215. One side of the mounting block 201 is fixedly connected to one side of the valve body 101, one side of the connecting block 205 is fixedly connected to one side of the valve seat 105, and one side of the placement block 215 is fixedly connected to the other side of the valve seat 105. There are two connecting blocks 205 and two placement blocks 215. A rotating column 207 is fixedly connected to the inner cavity of the mounting block 201, and a rotating plate 210 is movably connected to the surface of the rotating column 207. The inner cavity of 210 is movably connected to a threaded rod 203. The surface of the threaded rod 203 is threadedly connected to a second adjusting sleeve 213. One side of the second adjusting sleeve 213 is movably connected to one side of the rotating plate 210. One end of the threaded rod 203 is movably connected to a rotating shaft 212. Both ends of the rotating shaft 212 are fixedly connected to fixed plates 211. One side of the fixed plates 211 is fixedly connected to one side of the valve body 101. There are four fixed plates 211. One side of the connecting block 205 is fixedly connected to a fixed post 204. There are four fixed posts 204.

[0027] Reference Figure 6 A fixing groove 216 is provided on one side of the connecting block 205, and one side of the rotating plate 210 is inserted into the inner cavity of the fixing groove 216. The fixing groove 216 allows the rotating plate 210 to move inside the connecting block 205, and at the same time fixes the position of the connecting block 205, preventing the valve seat 105 from falling off under the action of external force.

[0028] Reference Figure 4 A movable groove 209 is provided on one side of the rotating plate 210. The surface of the threaded rod 203 is movably connected to the inner cavity of the movable groove 209. The movable groove 209 enables the threaded rod 203 to rotate inside the rotating plate 210 and guides the rotation of the threaded rod 203 to prevent it from deviating during rotation.

[0029] Reference Figure 4 A torsion spring 208 is slidably sleeved on the surface of the rotating column 207. There are four torsion springs 208, which are arranged in pairs. One end of the torsion spring 208 is fixedly connected to one side of the mounting block 201, and the other end of the torsion spring 208 is fixedly connected to the surface of the rotating plate 210. With the setting of the torsion spring 208, when the rotating plate 210 rotates, the torsion spring 208 is subjected to force and torsion and deforms. When the torsion spring 208 loses its deformation, it can drive the rotating plate 210 to reset.

[0030] Reference Figure 6A placement groove 214 is provided on one side of the inner cavity of the valve body 101. The surface of the placement block 215 is movably connected to the inner cavity of the placement groove 214. By setting the placement groove 214, the valve seat 105 can be effectively prevented from shaking under the flow of water, making the valve seat 105 more stable during operation.

[0031] Reference Figure 3 and Figure 6 The surface of the connecting block 205 is movably connected to a waterproof gasket 206. There are four waterproof gaskets 206, arranged in pairs. The waterproof gaskets 206 are made of graphite. With the setting of the waterproof gaskets 206 and the fact that the waterproof gaskets 206 are made of graphite, they can remain stable and not easily deformed under high temperature environment, and can effectively ensure sealing performance.

[0032] Reference Figure 3 and Figure 4 One end of the threaded rod 203 is fixedly connected to a limiting block 202. The diameter of the limiting block 202 is larger than the diameter of the threaded rod 203. By setting the limiting block 202, the position of the second adjusting sleeve 213 can be limited, so as to prevent the second adjusting sleeve 213 from detaching from the surface of the threaded rod 203 during the movement.

[0033] Working principle: By manually pulling the fixed column 204, the connecting block 205 moves, which in turn moves the valve seat 105. The valve seat 105 then moves the placement block 215 into the placement groove 214. When the placement block 215 reaches the inside of the placement groove 214, the rotating plate 210 is rotated by hand. One side of the rotating plate 210 rotates around the surface of the rotating column 207, causing one end of the rotating plate 210 to fit into the fixed groove 216, thus fixing the position of the valve seat 105 and installing it. The fixed groove 216 is centered on the rotating column 207. The waterproof gasket 206 prevents water from seeping through the gaps. Simultaneously, by manually pulling the threaded rod 203, it moves within the movable groove 209. One end of the threaded rod 203 rotates around the surface of the rotating shaft 212. When the threaded rod 203 rotates to a vertical position, the threaded connection between the threaded rod 203 and the second adjusting sleeve 213 causes the second adjusting sleeve 213 to move. When the second adjusting sleeve 213 moves to one side of the rotating plate 210, it fixes the position of the rotating plate 210. To prevent the rotating plate 210 from rotating under external force, when the valve body 101 is working, the first adjusting screw sleeve 104 is rotated by hand-gripping the rotating wheel 102. The gate 106 moves through the threaded connection between the first adjusting screw sleeve 104 and the lead screw 103, causing one side of the gate 106 to tightly fit against one side of the valve seat 105, thus opening and closing the valve. Then, the second adjusting screw sleeve 213 is rotated by hand. Through the threaded connection between the second adjusting screw sleeve 213 and the threaded rod 203, the second adjusting screw sleeve 213 disengages from one side of the rotating plate 210. Next, push the threaded rod 203 to move inside the moving groove 209, and one end of the threaded rod 203 rotates around the surface of the rotating shaft 212. Then, hold and rotate the rotating plate 210. One side of the rotating plate 210 rotates around the surface of the rotating column 207. The rotation of the rotating column 207 causes the torsion spring 208 to be deformed. When the torsion spring 208 loses its deformation, it can drive the rotating column 207 to reset. By holding and pulling the fixed column 204, the connecting block 205 is moved. The connecting block 205 drives the valve seat 105 to disengage from the inside of the valve body 101.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
