Description

Technical Field

[0001] This utility model relates to the field of bathroom ball valve technology, specifically a bathroom ball valve with high sealing performance. Background Technology

[0002] High-sealing bathroom ball valves typically refer to ball valves with excellent sealing performance used in bathroom equipment. These ball valves control the opening and closing by rotating the opening and closing element (ball) 90 degrees around the valve stem, ensuring that the water medium does not leak during the flow process, thereby meeting the high sealing requirements of bathroom equipment.

[0003] In the existing technology, bathroom ball valves usually use materials such as polytetrafluoroethylene (PTFE) as valve seat seals. Although these materials have excellent sealing performance and chemical stability, their temperature resistance is relatively low. Under long-term use or high-temperature environment, the sealing material may age and deform, resulting in a decrease in sealing performance. In addition, the existing seals are usually integrated, and when replacing the aged and deformed seals, the lock head needs to be removed, which is cumbersome.

[0004] Therefore, a bathroom ball valve with high sealing performance is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a bathroom ball valve with high sealing performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bathroom ball valve with high sealing performance, comprising a ball valve body, a water inlet pipe fixedly connected to one side of the ball valve body, a gasket movably fitted onto the outer wall of the water inlet pipe, a water outlet pipe fixedly connected to the side of the ball valve body perpendicular to the water inlet pipe, a rotating rod rotatably connected to the side of the ball valve body away from the water inlet pipe, and a pair of sliding plates slidably connected to the side of the ball valve body near the rotating rod. A first mounting shell and a second mounting shell are respectively fixedly connected to the sides of the sliding plates that are close to each other. A first sealing ring is detachably connected to the inner wall of the first mounting shell, and a second sealing ring is detachably connected to the inner wall of the second mounting shell. The first and second sealing rings are used to engage and seal the connection of the rotating rod.

[0007] Preferably, a pair of rigid sleeves are fixedly connected to the side of the first sealing ring near the second sealing ring, and a pair of rigid locking blocks are fixedly connected to the side of the second sealing ring near the first sealing ring, with the outer walls of the rigid locking blocks slidably locked onto the inner walls of the rigid sleeves.

[0008] Preferably, a pair of fixing plates are fixedly connected to the edge of the ball valve housing, and a bidirectional threaded rod is rotatably connected to the inner wall of the fixing plates. The outer wall of the bidirectional threaded rod is threaded to the inner wall of a pair of sliding plates, and a handwheel is fixedly connected to the end of the bidirectional threaded rod.

[0009] Preferably, the sliding plate is slidably connected to a slide frame on the side away from the bidirectional threaded rod, and the outer wall of the slide frame is detachably connected to the outer wall of the ball valve body.

[0010] Preferably, the shape formed by the first sealing ring and the rigid sleeve is U-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By using a rigid clip to engage with a rigid sleeve, the first and second sealing rings, which are divided into two parts, can be assembled by engaging and engaging. A bidirectional threaded rod is used to move the two parts relative to each other until the rigid clip engages with the rigid sleeve. This achieves the purpose of tightly fitting the inner walls of the first and second sealing rings against the outer wall of the rotating rod, so that the gap at the connection between the rotating rod and the ball valve body is effectively reinforced and sealed to prevent leakage, thereby improving the sealing performance.

[0013] 2. With the configuration of the first mounting shell, the second mounting shell, and the slide, the first sealing ring and the second sealing ring can be detached from the first mounting shell and the second mounting shell, making the replacement of the sealing ring simple and quick, avoiding the cumbersome steps of first disassembling the lock head in the traditional way. In addition, the detachable slide allows the remaining parts to be replaced, which is beneficial to the operation and maintenance of the device. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 5 An embodiment of this utility model is provided: a bathroom ball valve with high sealing performance, including a ball valve body 1, a water inlet pipe 5 fixedly connected to one side of the ball valve body 1, a gasket 4 movably sleeved on the outer wall of the water inlet pipe 5, a water outlet pipe 2 fixedly connected to the side of the ball valve body 1 perpendicular to the water inlet pipe 5, a rotating rod 3 rotatably connected to the side of the ball valve body 1 away from the water inlet pipe 5, a pair of sliding plates 8 slidably connected to the side of the ball valve body 1 close to the rotating rod 3, a first mounting shell 11 and a second mounting shell 12 fixedly connected to the sides of the sliding plates 8 close to each other, a first sealing ring 10 detachably connected to the inner wall of the first mounting shell 11, and a second sealing ring 15 detachably connected to the inner wall of the second mounting shell 12, the first sealing ring 10 and the second sealing ring 15 are used to snap and seal the connection of the rotating rod 3;

[0023] A pair of rigid sleeves 13 are fixedly connected to the side of the first sealing ring 10 near the second sealing ring 15, and a pair of rigid locking blocks 14 are fixedly connected to the side of the second sealing ring 15 near the first sealing ring 10. The outer walls of the rigid locking blocks 14 are slidably locked onto the inner walls of the rigid sleeves 13.

[0024] A pair of fixing plates 16 are fixedly connected to the edge of the ball valve body 1. The inner walls of the fixing plates 16 are rotatably connected to a bidirectional threaded rod 6. The outer wall of the bidirectional threaded rod 6 is threaded to the inner wall of a pair of sliding plates 8. A handwheel 7 is fixedly connected to the end of the bidirectional threaded rod 6.

[0025] The shape formed by the first sealing ring 10 and the rigid sleeve 13 is U-shaped;

[0026] Wherein: the bidirectional threaded rod 6 causes the first sealing ring 10 and the second sealing ring 15 to move relative to each other until the hard locking block 14 is engaged in the hard sleeve block 13, so as to achieve the purpose of the inner walls of the first sealing ring 10 and the second sealing ring 15 being tightly fitted to the outer wall of the rotating rod 3, so as to effectively strengthen and seal the gap at the connection between the rotating rod 3 and the ball valve body 1.

[0027] The sliding plate 8 is slidably connected to the slide frame 9 on the side away from the bidirectional threaded rod 6. The outer wall of the slide frame 9 is detachably connected to the outer wall of the ball valve body 1.

[0028] The first sealing ring 10 and the second sealing ring 15 are detachable from the first mounting shell 11 and the second mounting shell 12, making the replacement of the sealing ring simple and quick, avoiding the cumbersome steps of disassembling the lock head first.

[0029] The working principle of the above embodiment is as follows: When no water is needed, rotating the handwheel 7 drives the bidirectional threaded rod 6 to rotate, which in turn causes a pair of sliding plates 8 to move closer together. The sliding plates 8 can synchronously drive the first mounting shell 11 and the second mounting shell 12, thereby driving the first sealing ring 10 and the second sealing ring 15 closer together until the rigid locking block 14 is engaged in the rigid sleeve block 13, and the inner walls of the first sealing ring 10 and the second sealing ring 15 are tightly fitted against the outer wall of the rotating rod 3, thus reinforcing and sealing the gap at the connection between the rotating rod 3 and the ball valve housing 1 to prevent leakage. When it is necessary to rotate the lever 3 to open the water valve, the operation can be reversed to loosen the tightness appropriately, which helps to reduce the wear on the first sealing ring 10 and the second sealing ring 15 and increase their service life. In addition, when the first sealing ring 10 and the second sealing ring 15 are aged and deformed and need to be replaced, first move the sliding plate 8 to the farthest distance so that the hard block 14 is completely disengaged from the hard sleeve block 13. Then replace the first sealing ring 10 and the second sealing ring 15. The slide 9 can also be disassembled to replace the remaining parts, which is beneficial to the operation and maintenance of the device.
