Description

Technical Field

[0001] This utility model belongs to the technical field of valve body equipment, and in particular relates to a ball valve sealing structure. Background Technology

[0002] A ball valve is a commonly used gate valve. Its structure is similar to a small ball used in piping systems, with a channel on the ball. The ball valve seat sealing structure refers to the sealing structure used inside the ball valve to prevent leakage.

[0003] Existing ball valves control the opening and closing of water pipes by rotating the valve body. During this process, the sealing between the valve body and the water pipe is crucial, so a sealing structure is required to prevent leakage. Existing sealing structures are embedded inside the pipe, making them difficult to install and disassemble. Therefore, we provide a ball valve sealing structure to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a ball valve sealing structure. By rotating the valve pipe with the handle, the ball valve core rotates to open and close the water pipe. At the same time, by opening the second port, the sealing element of the ball valve core can be replaced, realizing the quick replacement of the sealing element. This solves the problems of existing sealing structures being embedded inside the pipe, making it difficult to install and disassemble the sealing element.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a ball valve sealing structure, including a pipe assembly, a valve assembly, and a plugging assembly. The pipe assembly includes a water pipe with an inlet on one side and an outlet on the other side. The valve assembly is installed inside the water pipe and includes a ball valve core rotatably disposed on the inner wall of the water pipe. The ball valve core has a water inlet. The plugging assembly is installed around the water pipe and includes a plugging ring that rotatably engages with the water pipe. A first opening is provided on the circumferential side of the plugging ring.

[0006] The present invention is further configured such that a second opening is provided on the circumferential side of the water pipe, the first opening corresponds to the second opening, a rotating opening is provided on the circumferential side of the water pipe, and blocking pipes are symmetrically arranged on the circumferential side of the water pipe.

[0007] The present invention is further configured such that the blocking pipe is internally connected to the water supply pipe, a sealing element is symmetrically slidably arranged on the circumferential side of the ball valve core, a sliding groove is symmetrically opened on the circumferential side of the ball valve core, a slider is fixedly arranged on the inner side of the sealing element, the slider and the corresponding sliding groove are slidably engaged, a plug rod is symmetrically slidably arranged on the inner side of the ball valve core, a plug hole is opened on the inner side of the sealing element, the plug rod and the corresponding plug hole are plugged into each other, and a limit groove is opened on one side of the plug rod.

[0008] The present invention is further configured such that a valve tube is fixedly provided on the circumferential side of the ball valve core, the valve tube is rotatably fitted with the rotating port, a handle is fixedly provided on the top of the valve tube, a valve stem is rotatably provided inside the valve tube, a handwheel is fixedly provided on the top of the valve stem, a rotating rod is fixedly provided on the bottom of the valve stem, the rotating rod is adapted to the limiting groove, a limiting plate is fixedly provided on the bottom of the plug rod, and an elastic reset member is fixedly provided between the two limiting plates.

[0009] The present invention is further configured such that a worm gear is fixedly provided on one side of the sealing ring, a connecting rod is fixedly provided on one side of the blocking pipe, an L-shaped connecting rod is fixedly provided on the periphery of the connecting rod, a worm is rotatably provided between the two L-shaped connecting rods, a drive motor is installed on one side of one of the L-shaped connecting rods, the output end of the drive motor is fixedly connected to the worm, and the worm meshes with the worm gear.

[0010] This utility model has the following beneficial effects: 1. By rotating the handwheel, the valve stem is driven to rotate. The rotating rod rotates until both ends of the rotating rod are away from the limiting groove. Under the action of the elastic reset member, the two plug rods move away from the corresponding plug holes, thereby releasing the restriction between the seal and the ball valve core. Then, the seal is taken out from the second port and replaced with a new seal. This process can realize the rapid replacement of the seal and improve the replacement efficiency of the seal.

[0011] 2. This utility model drives a drive motor to rotate a worm gear, which in turn drives a sealing ring to rotate, causing the first port and the second port to be misaligned until the second port is completely blocked by the sealing ring. This process completes the sealing of the water pipe and improves its sealing performance. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] For a specific implementation example, please refer to Implementation Example 1.

The valve assembly 2 is installed inside the water pipe 101 and includes a ball valve core 201, which is rotatably disposed on the inner wall of the water pipe 101. The ball valve core 201 has a water inlet 202. The plugging assembly 3 is installed around the water pipe 101 and includes a plugging ring 301, which is rotatably engaged with the water pipe 101. The plugging ring 301 has a first opening 302 on its circumferential side.

[0027] Specifically, a second opening 104 is provided on the side of the water pipe 101, and the first opening 302 corresponds to the second opening 104. A rotating opening 105 is provided on the side of the water pipe 101, and a blocking pipe 106 is symmetrically arranged on the side of the water pipe 101.

[0028] The operation process of this embodiment is as follows: In the initial state, the water inlet 202 is opposite to the blocking pipe 106. At this time, the water pipe 101 is in the closed state. When water needs to be supplied, the ball valve core 201 is rotated so that the water inlet 202 corresponds to the water inlet 102. At this time, the water can flow through the water inlet 202 and out from the water outlet 103.

[0029] In the second specific embodiment, based on the first specific embodiment, the blocking pipe 106 is internally connected to the water pipe 101, and the ball valve core 201 is symmetrically and slidably provided with a sealing element 203 on its circumferential side. The ball valve core 201 is symmetrically provided with a sliding groove on its circumferential side, and a slider is fixedly provided inside the sealing element 203. The slider and the corresponding sliding groove are slidably engaged.

[0030] Specifically, a plug rod 204 is symmetrically slidably arranged on the inner side of the ball valve core 201, and a plug hole 205 is opened on the inner side of the seal 203. The plug rod 204 is plugged into the corresponding plug hole 205. A limit groove 206 is opened on one side of the plug rod 204. A valve tube 207 is fixedly arranged on the circumferential side of the ball valve core 201. The valve tube 207 is rotatably engaged with the rotating port 105. A handle 208 is fixedly arranged on the top of the valve tube 207. A valve stem 209 is rotatably arranged inside the valve tube 207. A handwheel 210 is fixedly arranged on the top of the valve stem 209.

[0031] Furthermore, a rotating rod 211 is fixedly installed at the bottom of the valve stem 209, and the rotating rod 211 is adapted to the limiting groove 206. A limiting plate 212 is fixedly installed at the bottom of the plug rod 204, and an elastic reset member 213 is fixedly installed between the two limiting plates 212. A worm gear 303 is fixedly installed on one side of the sealing ring 301, and a connecting rod 304 is fixedly installed on one side of the blocking pipe 106. An L-shaped connecting rod 305 is fixedly installed on the circumferential side of the connecting rod 304, and a worm gear 306 is rotatably installed between the two L-shaped connecting rods 305. A drive motor 307 is installed on one side of one of the L-shaped connecting rods 305, and the output end of the drive motor 307 is fixedly connected to the worm gear 306. The worm gear 306 meshes with the worm wheel 303.

[0032] The operation process of this embodiment is as follows: In the initial state, the water inlet 202 is opposite to the blocking pipe 106, and the first port 302 is opposite to the second port 104. Then, the sealing member 203 is inserted into the circumferential side of the ball valve core 201, and the slider is inserted into the corresponding groove. Then, the handwheel 210 is turned to drive the valve stem 209 to rotate. The rotating rod 211 rotates until both ends of the rotating rod 211 are inserted into the limiting groove 206. During this process, the elastic reset member 213 is stretched, and the two insertion rods 204 are pushed into the corresponding insertion holes 205 by the rotating rod 211. At this time, the sealing member 203 is installed on the circumferential side of the ball valve core 201, thereby sealing the ball valve core 201. Then, the drive motor 307 is driven to drive the worm gear 306 to rotate. The worm wheel 303 rotates to drive the sealing ring 301 to rotate until the second port 104 is completely blocked. Then, the valve can be opened by rotating the handwheel 210. The handle 208 drives the valve pipe 207 to rotate, causing the ball valve core 201 to rotate and thus opening the water pipe 101. When the seal 203 needs to be replaced, the handle 208 is turned to drive the valve pipe 207 to rotate, causing the ball valve core 201 to rotate and thus closing the water pipe 101. Then, the drive motor 307 is driven to drive the worm gear 306 to rotate, and the worm wheel 303 rotates to drive the sealing ring 301 to rotate until the second port 104 is opened. Then, the handwheel 210 is turned to drive the valve stem 209 to rotate, and the rotating rod 211 rotates until both ends of the rotating rod 211 are away from the limiting groove 206. Under the action of the elastic reset member 213, the two plug rods 204 are moved away from the corresponding plug holes 205, so that the seal 203 and the ball valve core 201 are released from restriction. Then, the seal 203 is taken out from the second port 104 and a new seal 203 is replaced.
