Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick-opening valve technology, specifically a quick-opening valve core structure. Background Technology
[0002] To meet the demand for lightweight and low-cost household bathroom products (faucets, angle valves), the fully split ceramic quick-opening valve core has emerged. By separating the valve core sleeve, pressure cap, ceramic disc, and other components, the manufacturing difficulty is reduced, and the convenient operation of "90° rotation quick-opening" is achieved. It has quickly become the mainstream of household valve cores, with upgrades in both materials and processes: zirconia ceramic replaces traditional alumina, improving wear resistance by 2 times; the application of precision stamping and injection molding processes enables the mass production accuracy of the valve core to be controlled within 0.02mm, ensuring the ceramic disc fits and seals perfectly.
[0003] Existing quick-opening valve cores generally have a fixed internal water flow opening, which cannot adaptively adjust the water inlet according to the water flow pressure. When the pressure is too high, it will impact the components and easily cause leakage. Therefore, a quick-opening valve core structure is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a quick-opening valve core structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A quick-opening valve core structure includes a valve core housing, a limiting housing, a valve core rod, and an operating rod. The limiting housing is fixedly connected to the top of the valve core housing. The valve core rod is disposed inside the valve core housing and the limiting housing. The operating rod is fixedly connected to the top of the valve core rod. A sealing ring located inside the valve core housing is fixedly connected to the outer side of the valve core rod. Flow ports are opened on both sides of the valve core housing. A support ring is fixedly connected to the bottom of the valve core housing. A first ceramic moving plate is fixedly connected to the bottom of the valve core rod. The first ceramic moving plate has a first flow guide groove on both sides. Torque blocks are fixedly connected to both sides of the first ceramic moving plate. A second ceramic moving plate is fixedly connected to the inner side of the torque blocks. A second flow guide groove is opened on both sides of the second ceramic moving plate. A limit groove is opened on the inner side of the valve core housing. A limit block is provided on the inner side of the limit groove. A ceramic stationary plate located below the second ceramic moving plate is fixedly connected between the two limit blocks. A symmetrical pressure relief port is opened at the top of the ceramic stationary plate. A spring is fixedly connected between the ceramic stationary plate and the support ring.
[0007] Preferably, the inner shape of the limiting groove matches the shape of the limiting block, and the inner side of the limiting groove and the outer side of the limiting block fit together.
[0008] Preferably, the outer shape of the ceramic stationary plate matches the inner shape of the valve core housing, and the outer side of the ceramic stationary plate and the inner side of the valve core housing are in close contact with each other.
[0009] Preferably, there are two sealing rings, which are symmetrically arranged on the outside of the valve core rod.
[0010] Preferably, the inner diameter of the spring matches the inner diameter of the support ring, and the outer diameter of the spring matches the inner diameter of the valve core housing.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting components such as valve core shell, valve core rod, second ceramic moving plate, limiting groove, limiting block, ceramic stationary plate, pressure relief port and spring, the current water flow velocity can be adaptively adjusted according to the current flow pressure, expanding the water flow path, which can effectively relieve water pressure, avoid high pressure damage to components, and effectively avoid leakage in the valve core structure. This solves the problem that existing quick-opening valve cores generally have fixed internal water flow openings, cannot adaptively adjust the water inlet according to water pressure, and have the problem that when the pressure is too high, it will impact the components and easily cause leakage.
[0013] 2. In this utility model, the water flow can be guided by the specially shaped first and second guide channels, which can effectively reduce the impact force of contact with the water flow and effectively extend the service life. The extended torque block can effectively enhance the torque output, making the first ceramic moving plate rotate more easily. Attached Figure Description

[0023] Please see Figure 1-5 This utility model provides a technical solution:
[0024] A quick-opening valve core structure includes a valve core housing 1, a limiting housing 2, a valve core rod 3, and an operating rod 4. The limiting housing 2 is fixedly connected to the top of the valve core housing 1. The valve core rod 3 is disposed inside the valve core housing 1 and the limiting housing 2. The operating rod 4 is fixedly connected to the top of the valve core rod 3. A sealing ring 5 located inside the valve core housing 1 is fixedly connected to the outer side of the valve core rod 3. Flow ports 6 are opened on both sides of the valve core housing 1. A support ring 7 is fixedly connected to the bottom of the valve core housing 1. A first ceramic moving plate 8 is fixedly connected to the bottom of the valve core rod 3. A first ceramic moving plate 8 is opened on both sides of the first ceramic moving plate 8. The flow guide groove 9 has a torque block 10 fixedly connected to both sides of the first ceramic moving plate 8. The second ceramic moving plate 11 is fixedly connected to the inner side of the torque block 10. The second ceramic moving plate 11 has a second flow guide groove 12 on both sides. The valve core housing 1 has a limit groove 13 on the inner side. The limit groove 13 has a limit block 14 on the inner side. The two limit blocks 14 are fixedly connected to a ceramic stationary plate 15 located below the second ceramic moving plate 11. The top of the ceramic stationary plate 15 has a symmetrical pressure relief port 16. The ceramic stationary plate 15 and the support ring 7 are fixedly connected to a spring 17.
[0025] The inner shape of the limiting groove 13 matches the shape of the limiting block 14, and the inner side of the limiting groove 13 and the outer side of the limiting block 14 fit together, which can make the movement of the support ring 7 more stable; the outer shape of the ceramic stationary plate 15 matches the inner shape of the valve core housing 1, and the outer side of the ceramic stationary plate 15 and the inner side of the valve core housing 1 fit together, which can ensure the sealing effect at the edge; there are two sealing rings 5, which are symmetrically arranged on the outer side of the valve core rod 3, which can further improve the sealing effect between the valve core rod 3 and the valve core housing 1; the inner diameter of the spring 17 matches the inner diameter of the support ring 7, and the outer diameter of the spring 17 matches the inner diameter of the valve core housing 1.
[0026] Workflow: When a quick-opening valve core structure is required, the first ceramic moving plate 8 is rotated directly by the operating rod 4. The first ceramic moving plate 8 drives the torque block 10 to rotate, and the torque block 10 drives the second ceramic moving plate 11 to rotate. This aligns the first guide groove 9 and the second guide groove 12 with the flow port 6, opening the valve core structure and allowing water to flow through the flow port 6. The sealing ring 5 provides a good seal between the valve core housing 1 and the valve core rod 3. The first guide groove 9 and the second guide groove 12 work together to effectively divide the water flow channel and alleviate the pressure during water flow impact. When the water flow pressure is too high, the ceramic stationary plate 15 will be squeezed and moved downward under the guidance of the limiting groove 13 and the limiting block 14, compressing the spring 17. Under the action of the pressure relief port 16, the movement of the ceramic stationary plate 15 can be made more stable, thereby expanding the water flow channel and alleviating the pressure of water flow impacting the valve core structure.
