Description

Angle valve Technical Field

[0001] This utility model relates to the field of pipeline connection structure technology, and more specifically to an angle valve. Background Technology

[0002] Angle valves are common interface control components in bathroom and kitchen water supply systems. They are widely used to connect faucets, water heaters, washing machines, toilets, and other appliances to wall-mounted water supply pipes. Their basic function is to control water flow and provide a transitional connection. Traditional angle valves typically include basic components such as a valve body, switch, and outlet. Their structure is relatively simple, and the installation method is also relatively straightforward, usually connecting to wall pipes via threads.

[0003] However, existing angle valves have the following technical problems in actual use:

[0004] 1. Inconvenient installation and poor adaptability: The valve body of a standard angle valve connects directly to the wall-mounted water supply interface. If the wall's pre-embedded depth is not standard, the angle valve may be installed too deeply or too shallowly, affecting the aesthetics of the installation and subsequent pipe connections. In addition, wall errors or pipe misalignment will also increase the difficulty of construction.

[0005] 2. Sealing performance depends on waterproof tape, which is uncertain: Traditional angle valve connections often rely on workers to manually wrap sealing tape (such as PTFE tape, hemp fiber, etc.) to achieve a seal. However, due to the difficulty in standardizing the wrapping quality, it is very easy to cause seal failure, resulting in water leakage or seepage problems, especially under high water pressure environments.

[0006] 3. High degree of structural integration, difficult maintenance and replacement: Most angle valves have their outlet structure and control mechanism integrated into a single housing, which is compact but not conducive to later disassembly and maintenance. Once the internal valve core or connection port fails, the entire part usually needs to be replaced, which is costly and labor-intensive.

[0007] 4. Lack of unified transition between decoration and pipe fitting interfaces: Traditional angle valves are often exposed on the outside of the wall, with a rough appearance that is difficult to coordinate with the aesthetic requirements of modern bathrooms, kitchens, and other spaces. Some users may install decorative covers to improve the aesthetics, but these often cannot be properly fitted due to limitations in pipe length and interface position, resulting in a decrease in both aesthetics and installation stability.

[0008] In summary, existing angle valves have limitations in terms of ease of installation, sealing reliability, structural maintainability, and appearance compatibility. There is an urgent need for an improved angle valve to solve these problems. Summary of the Invention

[0009] The purpose of this utility model is to provide an angle valve whose structural improvement focuses on setting an independent connecting seat to form an intermediate connection interface between the angle valve body and the extension tube, thereby realizing the detachable installation and channel connection of the extension tube; at the same time, the extension tube penetrates the wall and extends to the outside of the angle valve cover, which facilitates decorative installation.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Angle valve, including: switch, angle valve body, rotating head, connecting seat, extension tube, angle valve cover and connecting tube;

[0012] The upper end of the angle valve body is provided with an opening, and the switch is rotatably connected to the angle valve body through an axial connection.

[0013] The rotating head is a sleeve structure, which is sleeved on the outside of the angle valve body;

[0014] The lower end of the angle valve body is provided with a first threaded part, which is threadedly connected to the upper end of the connecting seat.

[0015] The other end of the connector is provided with a second threaded part, which is threaded to the upper end of the extension tube;

[0016] The extension tube is connected to the angle valve body via a connecting seat and extends to the outside of the angle valve cover;

[0017] The lower end of the extension tube is provided with a third threaded part, which is threadedly connected to the connecting tube.

[0018] The angle valve cover is fitted onto the outside of the extension pipe and is fixedly fitted to the outer surface of the wall.

[0019] Preferably, a first sealing ring is provided between the connecting seat and the extension tube; a second sealing ring is provided between the angle valve cover and the extension tube.

[0020] Preferably, the extension tube is provided with a first mounting groove and a second mounting groove, the first sealing ring is disposed in the first mounting groove, and the second sealing ring is disposed in the second mounting groove.

[0021] Preferably, the rotating head has a water outlet on its side wall, and the water outlet is connected to the internal cavity of the angle valve body.

[0022] Preferably, the rotating head has a mounting base inside, the valve is disposed in the mounting base and slides with the mounting base; the lower end of the switch has a rotating column, which is threadedly connected to the upper end of the valve.

[0023] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting a connecting seat, its two ends are respectively connected to the angle valve body and the extension pipe threadedly to form a stable transition section. The extension pipe can be passed through the outside of the wall to facilitate the installation of the decorative cover.

[0025] 2. The extension tube has multiple mounting slots, which are used to accommodate the sealing rings. They cooperate with the connecting seat and the angle valve cover to form a seal, eliminating the need for waterproof tape and improving sealing efficiency.

[0026] 3. The rotating head is mounted on the outside of the angle valve body, with an independent structure to avoid interference. At the same time, the water outlet is located on the rotating head, allowing for more flexible arrangement of the pipeline outlet direction.

[0027] 4. The valve is installed inside the mounting base of the rotating head and slides with the mounting base. It works with the rotating column to open and close. The structure is clear and easy to disassemble and assemble. Attached Figure Description

[0034] Example

[0035] As shown in Figures 1 to 3, this embodiment provides an angle valve, including a switch 1, an angle valve body 2, a rotating head 3, a connecting seat 4, an extension tube 5, an angle valve cover 6, and a connecting tube 7.

[0036] The angle valve body 2 is a hollow structure with an opening at its upper end. A switch 1 is located at the upper end of the angle valve body 2, inserted vertically and forming an axial rotational fit with the body, used to control the position of internal components. A rotating post 101, a cylindrical rod, is located at the lower end of the switch 1, and its lower end is connected to the upper end of the valve 102 via a threaded connection. The external thread of the rotating post 101 can be screwed into the internal threaded hole of the valve 102, forming a secure fit.

[0037] The rotating head 3 is a sleeve-shaped structure, fitted onto the outside of the angle valve body 2, with its inner cavity maintaining a clearance fit with the outer wall of the angle valve body 2. A water outlet 301 is provided on the side wall of the rotating head 3. The water outlet 301 is a transverse opening located in the middle of the rotating head 3, communicating with the internal cavity of the angle valve body 2 through a gap channel between the rotating head 3 and the angle valve body 2. The water outlet 301 has a threaded pipe structure, facilitating the connection of external water pipes or hoses.

[0038] The rotating head 3 has a mounting base 302 inside. The mounting base 302 is cylindrical and fixedly mounted on the central axis of the inner cavity of the rotating head 3, with an open lower end and a closed upper end. The valve 102 is located inside the mounting base 302 and can slide up and down in the vertical direction, forming a sliding fit with the mounting base 302. The lower end of the valve 102 is used to close or open the internal passage of the angle valve, and its upper end is threadedly connected to the rotating column 101 to achieve axial movement when the rotating column rotates.

[0039] The lower outer periphery of the angle valve body 2 is provided with a first threaded portion, which is threadedly connected to the upper end of the connecting seat 4. The connecting seat 4 has a short cylindrical structure, forming a transitional connecting component between the angle valve body 2 and the extension tube 5. The lower outer wall of the connecting seat 4 is provided with a second threaded portion, which is threadedly connected to the upper end of the extension tube 5.

[0040] The extension pipe 5 is a slender, hollow structure that passes axially through the connecting seat 4 and communicates with the internal cavity of the angle valve body 2. The lower end of the extension pipe 5 has a third threaded section that connects to the internal thread of the connecting pipe 7. The connecting pipe 7 can be a metal or plastic connector, and its other end is connected to the water supply pipe inside the wall.

[0041] To achieve a good seal, the outer surface of the extension tube 5 is provided with two annular mounting grooves, namely the first mounting groove 501 and the second mounting groove 502. The first mounting groove 501 is located at the upper end of the extension tube 5 near the connecting seat 4, and a first sealing ring 401 is embedded therein. The first sealing ring 401 is located in the inner cavity of the connecting seat 4, and is used to form a circumferential seal between the extension tube 5 and the connecting seat 4. The second mounting groove 502 is located in the middle section of the extension tube 5, corresponding to the fitting position of the angle valve cover 6, and a second sealing ring 601 is embedded therein, and is used to form a seal between the extension tube 5 and the angle valve cover 6.

[0042] The angle valve cover 6 has a cylindrical structure, the inner diameter of which matches the outer diameter of the extension pipe 5. It is fitted onto the outer surface of the extension pipe 5 from the outside and pressed tightly against the wall surface. The angle valve cover 6 can be fixed to the wall by a snap-fit ​​structure, a threaded structure, or an adhesive structure to cover the pipe outlet and improve aesthetics.

[0043] In actual installation, first connect the connecting pipe 7 to the wall water supply pipe via thread, then connect the extension pipe 5 to the connecting pipe 7 via the third thread. The upper end of the extension pipe 5 is connected to the connecting seat 4 via the second thread, and the first sealing ring 401 is embedded in the first mounting groove 501, pressing against the inner cavity of the connecting seat 4 to form a seal. The lower end of the angle valve body 2 is connected to the connecting seat 4 via the first thread, thus forming a water passage from the wall to the angle valve body. Then, the angle valve cover 6 is fitted onto the outside of the extension pipe 5 from the outside, and the cover is pressed tightly by the second sealing ring 601 on its inner side, finally fixing it to the wall to complete the decorative cover.

[0044] The structural solution provided in this embodiment securely connects the angle valve body 2 and the extension pipe 5 through the double-ended threaded connection of the connecting seat 4, thus establishing a sealed channel for easy installation and disassembly. Simultaneously, the extension pipe 5 extends through the exterior of the wall, allowing for aesthetically pleasing installation in conjunction with the angle valve cover 6, eliminating the need for additional waterproof tape or other materials, thereby improving on-site construction efficiency and sealing reliability.
