Description

Technical Field

[0001] The utility model relates to the technical field of angle valves, in particular to an anti-leakage angle valve with high water passing efficiency. Background Art

[0002] Angle valve is an angle stop valve. Angle valve is similar to ball valve, and its structure and characteristics are modified from ball valve. The difference from ball valve is that the outlet and inlet of angle valve are at a right angle of 90 degrees. Angle valve is also called triangle valve, angle valve, angle valve. This is because the pipe forms a 90-degree angle at the angle valve, so it is called angle valve, angle valve, angle valve.

[0003] For example, the Chinese patent "CN217603442U" discloses a leak-proof self-closing angle valve, which proposes: a leak-proof self-closing angle valve, including a valve body with a water inlet and a water outlet, a quick-connect sleeve with a water pipe connected to the water inlet of the valve body, an inner seat radially protruding outward in the valve body and corresponding to the water inlet, a detachable water-passing seat is arranged between the quick-connect sleeve and the inner seat, the front and rear ends of the water-passing seat are recessed with slow-flow grooves, the slow-flow groove and the end face of the water-passing seat are transitioned through an annular transition surface, a middle hole for water supply is arranged in the middle of the water-passing seat, and a number of water-passing holes are distributed around the middle hole on the water-passing seat, both ends of the water-passing hole are tapered holes with large openings outside and small openings inside, the middle of the water-passing hole is a cylindrical hole, a sealing ring 1 is arranged between the water-passing seat and the inner seat, and a sealing ring 2 is arranged on the water-passing seat and between the quick-connect sleeve. It has the advantages of preventing leakage and improving the use effect and service life of the angle valve.

[0004] It can be seen from the above-mentioned device that although the above-mentioned device has a good solution for the leakage of the angle valve during use, the applicant believes that the following defects still exist:

[0005] Existing angle valves usually use a spiral valve core structure, and the opening is small and the water flow efficiency is low. In scenarios where high water pressure is required, such as using a water heater for bathing, it cannot provide a high water flow efficiency. In the closed state, the sealing performance between the valve core and the valve seat is poor. When the valve body is offset during long-term use, water leakage or seepage is likely to occur, resulting in a short service life and poor sealing. Utility Model Content

[0028] See also Figure 3-4 , a leak-proof angle valve with high water passing efficiency, including a valve body 1, a switch assembly 2, and a valve core assembly 3. The valve core assembly 3 includes a fastening water seal 31. Sliders 32 are arranged at the protrusions on both sides of the fastening water seal 31. The design of the fastening water seal 31 is to ensure the sealing of the valve and prevent water from leaking from the valve. Sliders 32 are arranged at the protrusions on both sides. The main function of these slides 32 is to help the fastening water seal 31 remain stable during the switching process, reduce friction and possible wear, and connecting rods 33 are arranged under the protrusions on both sides of the fastening water seal 31. The outer wall of the connecting rod 33 is fixedly installed with a limit plate 34. The fitting surface of the limit plate 34 is set to a smooth arc surface. The fitting surface of the limit plate 34 is tightly fitted with a ball valve 35. In order to reduce friction and wear, the fitting surface of the limit plate 34 is set to a smooth arc surface. This design helps ensure that the slider 32 can smoothly fit the surface of the limit plate 34 when moving, thereby improving the smoothness of valve operation and extending its service life. The ball valve 35 fits tightly on the fitting surface of the limit plate 34, which helps to accurately control the flow direction and flow rate of water when the valve is opened or closed. This tight fit ensures the stable transmission of water flow and reduces possible water leakage. The ball valve 35 is provided with a through water outlet, and a water inlet is provided below the ball valve 35. The water outlet and the outer edge of the water inlet are both fitted with a sealing gasket 36.

[0029] See also Figure 1-2, a mounting thread is provided at the bottom of the outer wall of the valve body 1, and the mounting thread is a threaded hole used to fix the valve body 1 to other structures or equipment. This design enables the valve body 1 to be stably installed on the water inlet pipe and ensures its stability under the action of water flow. The valve body 1 is mounted with the water inlet pipe through the threaded engagement at the bottom. A water outlet 11 is provided on the outer wall of the valve body 1, and a connecting thread is provided on the outer wall of the water outlet 11. The connecting thread is a thread provided on the outer wall of the water outlet 11, and its purpose is to be engaged and connected with the water outlet pipe. This design enables the water outlet 11 to be stably connected with the water outlet pipe, ensuring the smooth transmission of water flow. The water outlet 11 is mounted with the water outlet pipe through the threaded engagement on the outer wall. A gasket 12 is provided inside the valve body 1, and the gasket 12 is provided below the ball valve 35. The gasket 12 is located inside the valve body 1 to provide support for the ball valve 35. Its design helps to ensure the stable position of the ball valve 35 in the valve body 1 and reduce external factors that may cause damage to it. The pad 12 is provided with a water inlet and its size is consistent with the water inlet below the ball valve 35. The water inlet design of the pad 12 ensures the uniform distribution of the water flow, and through the consistent size with the water inlet below the ball valve 35, the smooth introduction of the water flow is achieved. The water inlet of the pad 12 fits the sealing gasket 36 below the ball valve 35, and the water inlet of the pad 12 fits tightly on the sealing gasket 36 below the ball valve 35. This fitting design enhances the sealing performance and further prevents water leakage. An annular slide 13 is provided inside the valve body 1, and the sliders 32 on both sides of the fastening water seal 31 are movably installed inside the slide 13, and the block 32 is movably installed along the inside of the slide 13. This design allows the slider 32 to slide on the protrusions on both sides of the fastening water seal 31, thereby assisting the stable movement of the water seal 31 during the opening and closing of the valve.

[0030] See also Figure 2-3 The switch assembly 2 includes a connecting shaft 23 and a swivel 24. The connecting shaft 23 is fixedly mounted above the ball valve 35. The fastening water seal 31 is fixedly mounted on the outer wall of the connecting shaft 23. The fastening water seal 31 fits above the inner wall of the valve body 1. The fastening water seal 31 fits tightly above the inner wall of the valve body 1. This fitting design enhances the sealing performance and prevents water from leaking from the gap between the fastening water seal and the inner wall of the valve body. The outer wall of the connecting shaft 23 is fixedly mounted with an anti-skid gasket 22. The anti-skid gasket 22 is fixedly mounted on the outer wall of the connecting shaft 23, mainly used to increase friction, prevent slipping during rotation, and ensure the stability and accuracy of rotation. A clamping joint 21 is fixedly mounted above the connecting shaft 23. The clamping joint 21 is clamped inside the swivel 24 through surface clamping teeth. The anti-skid gasket 22 is also movably mounted inside the swivel 24. The swivel 24 is arranged above the valve body 1.

[0031] Working principle: First, when installing the anti-leakage angle valve, install it on the water inlet pipe through the installation thread at the bottom of the outer wall of the valve body 1, and then install the water outlet pipe through the connecting thread on the outer wall of the water outlet 11. After that, you can rotate the swivel 24 and drive the ball valve 35 to rotate through the connecting shaft 23 under the swivel 24 to control the switch of the valve. When the swivel 24 is rotated, the anti-skid gasket 22 inside the swivel 24 follows the rotation to prevent the swivel from rotating, increase the friction to prevent slipping, and make the rotation more accurate to control the water flow. Since the water outlet of the ball valve 35 is through, the water outlet efficiency is greatly improved compared with the ordinary angle valve. When the ball valve 35 is rotated to close, the outer The limit plate 34 of the wall rotates together, and the limit plate 34 slides in the slide groove 13 through the sliders 32 on both sides of the water seal 31 fastened above. The slide groove 13 limits the movement of the slider 32, so that each time the rotary head 24 is rotated, the limit plate 34 can maintain the same position to limit the movement of the ball valve 35, making the ball valve 35 more stable and accurate, and preventing the ball valve from shifting after repeated use, resulting in inaccurate fit of the outer wall to the sealing gasket 36 at the water outlet 11, and failing to achieve a sealing effect. When the outer wall of the ball valve 35 fits the sealing gasket 36 at the water outlet 11, the ball valve blocks the water outlet 11, so that the water outlet is closed to prevent liquid leakage.
