[0002] Ball valve assemblies are usually used in the field of fluid control, especially in the industrial, water conservancy, and construction industries, and are widely used due to their high efficiency in opening, closing, and flow regulation.

[0003] Existing ball valves are generally installed in pipelines through multiple bolts and flanges. However, during long-term use, the ball valves are inevitably damaged and need to be disassembled and replaced. During the replacement process, multiple bolts need to be removed one by one, which is rather cumbersome to operate, resulting in a low disassembly and replacement efficiency.

[0004] Therefore, a ball valve assembly is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a ball valve assembly to solve the problems mentioned in the above background art.

[0026] As Figures 1 to 6 shown, a ball valve assembly includes a housing 1. A second connecting pipe 6 is fixedly connected to the left side of the housing 1. A pressing plate 3 is attached to the right side of the housing 1. A first connecting pipe 5 is threadedly connected to the right side surface of the pressing plate 3. A positioning assembly 4 for connecting to the housing 1 is provided on the surface of the pressing plate 3. An opening and closing control assembly 2 is installed on the surface of the housing 1. More specifically, the second connecting pipe 6 and the first connecting pipe 5 are respectively connected to pipelines. The inside of the housing 1 can be controlled to be conducted through the opening and closing control assembly 2, thereby controlling the flow of the medium. The locking of the housing 1 is released through the positioning assembly 4, so that the housing 1 and the pressing plate 3 can be separated from each other, thereby enabling the rapid disassembly of the housing 1.

[0027] The opening and closing control assembly 2 includes a sleeve 201, and the sleeve 201 is fixedly connected to the housing 1. A connecting shaft 202 is rotatably connected to the inner wall of the sleeve 201. A ball valve core 204 is fixedly connected to the bottom end of the connecting shaft 202, and the ball valve core 204 is rotatably connected to the inner wall of the housing 1. A joint 203 is fixedly connected to the top end of the connecting shaft 202. It should be noted that by turning the joint 203 with a wrench, the connecting shaft 202 is driven to rotate along the inner wall of the sleeve 201, so as to control the rotation of the ball valve core 204, thereby controlling the internal conduction of the housing 1.

[0028] Sealing rings 205 are fixedly connected to both the bottom end and the top end of the sleeve 201. More specifically, by arranging the sealing rings 205 at both ends, the position of the sleeve 201 can be sealed to avoid leakage.

[0029] The positioning assembly 4 includes a swivel sleeve 401, and the swivel sleeve 401 is threadedly connected to the pressing plate 3. A connecting ring 402 is rotatably connected to the left end of the swivel sleeve 401. A connecting rod 408 is hinged to the left side surface of the connecting ring 402. A positioning block 406 is hinged to the end of the connecting rod 408. A sliding groove 407 is formed on the right side surface of the pressing plate 3, and the inner wall of the sliding groove 407 is slidably connected to the positioning block 406. An insertion block 403 is fixedly connected to the right side surface of the housing 1. A jack 404 is formed through the surface of the pressing plate 3, and the inner wall of the jack 404 is movably inserted with the insertion block 403. A positioning groove 405 is formed on the surface of the insertion block 403, and the inner wall of the positioning groove 405 is movably inserted with the positioning block 406. It should be noted that by rotating the swivel sleeve 401, under the action of the thread, the swivel sleeve 401 will move to the right, thereby pulling the connecting ring 402 to move. The connecting ring 402 will then pull the end of the connecting rod 408 to move. The left end of the connecting rod 408 pulls the positioning block 406 to slide along the inner wall of the sliding groove 407, and the end of the positioning block 406 will disengage from the inner wall of the positioning groove 405. Then, by pulling the housing 1 or the pressing plate 3, the insertion block 403 is disengaged from the inner wall of the jack 404, and the housing 1 can be disassembled.

[0030] A slider 409 is fixedly connected to the inner wall of the connecting ring 402. A limiting groove 410 is formed on the surface of the pressing plate 3, and the inner wall of the limiting groove 410 is slidably connected to the surface of the slider 409. More specifically, when the connecting ring 402 moves, it will drive the slider 409 to slide along the inner wall of the limiting groove 410. Through the cooperation of the slider 409 and the swivel sleeve 401, the connecting ring 402 can be limited to prevent the connecting ring 402 from rotating.

[0031] A sealing gasket is fixedly connected to the left side surface of the pressing plate 3, and the sealing gasket is in contact with the right side surface of the housing 1. It should be noted that by arranging the sealing gasket, the sealing performance of the contact surface between the housing 1 and the pressing plate 3 is enhanced to avoid leakage.

[0032] In summary: The second connecting pipe 6 and the first connecting pipe 5 are respectively connected to the pipeline. The opening and closing control assembly 2 can control the internal conduction of the housing 1, thereby controlling the flow of the medium. By means of the positioning assembly 4, the locking of the housing 1 is released, so that the housing 1 and the pressing plate 3 can be separated from each other, thus enabling the rapid disassembly of the housing 1. The effect of facilitating the rapid disassembly and replacement of the ball valve is achieved during use. Compared with the traditional fixing method using bolts and flanges, the disassembly is more convenient, thus improving the disassembly and replacement efficiency.
