Description

Technical Field

[0001] The present invention relates to the technical field of pipeline connection structures, and more particularly to an angle valve. Background Art

[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 primary function is to control water flow and provide a transitional connection. Traditional angle valves typically consist of a valve body, switch, and outlet, offering a relatively simple structure and straightforward installation, often connecting to wall pipes via threads.

[0003] However, the existing angle valve has the following technical problems during actual use:

[0004] 1. Inconvenient installation and poor adaptability: The valve body of a conventional angle valve is directly connected to the water supply interface on the wall. If the pre-buried wall depth is not standard, it is very easy to cause the angle valve to be installed too deep or too deep, affecting the installation aesthetics and subsequent pipe connection. In addition, wall errors or pipe deviations can also increase the difficulty of installation.

[0005] 2. Sealing performance depends on waterproof tape, which is uncertain: Traditional angle valve joints often rely on workers to manually wrap sealing tape (such as raw tape, hemp, etc.) to achieve sealing. However, since the winding quality is difficult to standardize, it is very easy to cause sealing failure, leakage or seepage problems, especially in 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 an integrated housing. This compact structure makes disassembly and maintenance difficult. Failure of the internal valve core or connector typically requires complete replacement, which is costly and labor-intensive.

[0007] 4. Lack of uniform transition between the decoration and the pipe interface: Traditional angle valves are often exposed on the wall, resulting in a rough appearance that is difficult to coordinate with the aesthetic requirements of modern bathrooms, kitchens, and other spaces. Some users install decorative covers to improve the appearance, but this often fails to fit well due to the extended pipe length and limited interface location, resulting in a reduced aesthetic and installation security.

[0008] In summary, existing angle valves have limitations to varying degrees in terms of installation convenience, sealing reliability, structural maintainability, and appearance adaptability. There is an urgent need for an angle valve with an improved structure to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example

[0041] like Figures 1 to 3 As shown, the present invention provides an angle valve, which comprises a switch 1, an angle valve body 2, a rotating head 3, a connecting seat 4, an extension pipe 5, an angle valve cover 6, and a connecting pipe 7. This angle valve structure is mainly used for connecting and controlling the on / off of pre-buried water supply pipes in locations such as toilets, kitchens, and bathrooms.

[0042] The angle valve body 2 is a hollow shell with a circular opening at the top for mounting the switch 1. The switch 1 and the angle valve body 2 are rotatably connected. A rotating post 101 is connected to the bottom end of the switch 1. This post 101 has an externally threaded structure, and its threaded end engages with a threaded hole in the valve 102. Rotating the switch 1 drives the rotating post 101, which in turn drives the valve 102 to slide axially, achieving on / off control.

[0043] The valve 102 is mounted within a mounting seat 302 within the rotating head 3. The mounting seat 302 is fixed to the center of the rotating head 3 and integrally formed therewith. The mounting seat 302 is a hollow cylindrical structure, the inner surface of which slidably engages with the valve 102, guiding its lifting and lowering motion. A stopper is provided at the lower end of the mounting seat 302, which cooperates with the sealing surface at the lower end of the valve to form a valve port seal.

[0044] The rotating head 3 is sleeved on the outside of the angle valve body 2, and its side wall is provided with a water outlet 301, which is an externally threaded short pipe for connecting to a hose or a shower interface. The water flow derived from the valve body cavity is guided to the outside through the water outlet 301.

[0045] In terms of valve sealing, the present invention specially designs a double switch sealing structure:

[0046] A seal is provided between the rotating column 101 and the angle valve body 2;

[0047] Another seal is located between the valve 102 and the mounting seat 302 .

[0048] Even if one of the sealing structures fails due to aging or wear, the other can still maintain the seal, thereby improving the reliability and service life of the structure.

[0049] The lower end of the angle valve body 2 is provided with an externally threaded section, which is threadedly connected to the upper end of the connecting base 4, forming a first connection. The connecting base 4 is a short, hollow cylindrical connector with a second externally threaded section at its lower end, which is threadedly connected to the upper end of the extension tube 5, forming a second connection. A first sealing ring 401 is installed between the connecting base 4 and the extension tube 5. This sealing ring is installed in the first mounting groove 501 of the extension tube 5 and is pressed and sealed after being inserted into the connecting base 4.

[0050] The present invention achieves adjustable installation and docking capabilities through the structure of the connector 4. Even if the PPR pipe embedded in the wall is misaligned or the length is inaccurate, the threaded structure between the extension pipe 5 and the connector 4 still provides an installation length adjustment margin of approximately 0 to 35 mm, eliminating the need for additional extension joints or pipe cutting operations, greatly simplifying installation.

[0051] The lower end of the extension pipe 5 is provided with a third threaded section, which is threadedly connected to the connecting pipe 7. The connecting pipe 7 is used to be connected to the water supply pipe inside the wall and is usually made of copper or high-strength plastic.

[0052] The middle section of the extension tube 5 is provided with a second mounting groove 502 for mounting a second sealing ring 601. The angle valve cover 6 is a forged stainless steel decorative cover with a corresponding second sealing ring 601 mounted on its inner wall. During installation, the cover is inserted into the extension tube 5 from the outside, pressing the second sealing ring 601 against the outer wall of the extension tube. Once assembled, this structure forms an effective seal against the wall. Even during daily flushing or in humid environments, it prevents water or vapor from entering the PPR pipe opening inside the wall along the extension tube, thus resolving the chronic water seepage, damp and moldy walls, odor generation, and bacterial growth issues associated with traditional angle valves.

[0053] After the valve is installed, the water outlet 301 is located on the side wall of the rotating head and is connected to the interior of the angle valve body. Since the rotating head 3 and the angle valve body 2 are configured with a limited rotational fit, the user can rotate and adjust the angle of the rotating head as needed, thereby unifying or specifying the water outlet direction. This avoids the difficulty of aligning the water outlet angle after traditional angle valve installation, improving the overall consistency and convenience of construction and use.

[0054] In summary, the angle valve of the present invention achieves practical improvement through the following structural innovations:

[0055] 1. The thread adjustment structure of the connecting seat + extension pipe solves the problems of PPR pipe pre-embedding error and depth adaptation;

[0056] 2. The extension tube is designed with double sealing rings, corresponding to the connection seat and the decorative cover connection part respectively, to achieve water stop-free installation;

[0057] 3. Double sealing structure design of the switch part to improve service life and sealing safety;

[0058] 4. Adjustable water outlet structure to ensure uniform installation;

[0059] 5. The decorative cover is forged and pressed to seal the wall, effectively preventing water vapor from penetrating into the wall and protecting the decoration environment.

[0060] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
