Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] This utility model provides a universal angle valve, such as Figure 1-3 As shown, the valve includes an angle valve body 100 and a valve core. The angle valve body 100 includes an inlet section 110 and an outlet section 120. The axes of the inlet section 110 and the outlet section 120 are set at an angle. The valve core rod 230 of the valve core is coaxially arranged with the outlet section 120.

[0035] The valve core is provided with one end of the valve core rod 230 connected to the water outlet section 120 and the other end connected to the water outlet connector 130;

[0036] The portion of the valve core located outside the water outlet section 120 is fitted with a handwheel 300 for adjusting the valve core to open or close the water outlet section 120.

[0037] In this application, the handwheel 300 is mounted on the outside of the core valve. The core valve, the outlet connector 130, and the handwheel 300 are coaxially arranged. Compared with the handwheel 300 being mounted on one side of the core valve, this application imposes less restriction on the installation direction of the angle valve. The angle valve can rotate around the inlet section 110 as an axis, allowing its installation direction to be flexibly selected, achieving "universal" orientation. This is beneficial for adjusting the installation direction of the angle valve according to environmental needs to avoid other facilities or make reasonable use of space.

[0038] Furthermore, in this application, the angle valve body includes a plastic shell and a metal insert embedded inside the plastic shell. The metal insert is located within the water outlet section. The plastic shell can be made of PPR or similar materials, and the metal insert can be a copper insert. In this way, the angle valve body can be obtained by injection molding, which helps to simplify the production process and reduce costs.

[0039] Specifically, the angle between the axes of the inlet section 110 and the outlet section 120 is usually 90°. In some other special application scenarios, the angle between the axes of the inlet section 110 and the outlet section 120 may not be 90° depending on actual needs.

[0040] In an optional embodiment, the valve core includes a valve core body 200 fixed to the angle valve body 100. A first ceramic plate 210 and a second ceramic plate 220 are disposed inside the valve core body 200. A first channel is provided on the first ceramic plate 210, and a second channel is provided on the second ceramic plate 220. The second ceramic plate 220 is fixedly connected to a valve core rod 230 for controlling the rotation of the second ceramic plate 220 to adjust the degree of overlap between the first channel and the second channel. The handwheel 300 is sleeved on the valve core rod 230 and fixedly connected to the valve core rod 230.

[0041] Specifically, the valve core rod 230 is fixedly connected to the second ceramic plate 220. The valve core rod 230 can rotate under the drive of the handwheel 300, thereby driving the second ceramic plate 220 to rotate. When the second ceramic plate 220 rotates to the designated position, the overlap area between the first channel and the second channel is the largest, and the universal angle valve achieves the maximum opening. If the handwheel 300 is continued to rotate, the second ceramic plate 220 continues to rotate, and the overlap area between the first channel and the second channel gradually decreases, eventually achieving a zero overlap area between the first channel and the second channel, at which point the universal angle valve closes.

[0042] In some embodiments, a sealing ring can be provided between the valve core rod 230 and the valve core body to improve the sealing degree between the two.

[0043] In some embodiments, one end of the water outlet connector 130 is inserted into the valve core rod 230 and a retaining ring 600 is provided between the connector and the valve core rod 230 to fix the valve core rod 230 and the water outlet connector 130.

[0044] In some embodiments, when the angle valve body 100 is made of PPR material, in order to ensure a stable connection between the angle valve body 100 and the valve core body 200, an insert can be provided inside the angle valve body 100. The insert and the valve core body can be connected by threads, and a sealing ring is provided between the insert and the valve core body.

[0045] In an optional embodiment, a first sealing ring 240 is provided at the connection between the valve core body and the angle valve body 100. The first sealing ring 240 is located on the side of the first ceramic plate 210 away from the second ceramic plate 220. A support groove is provided inside the first sealing ring 240, and a support ring 250 is provided in the support groove for pressing the first sealing ring 240 against the inner wall of the valve core body.

[0046] The first sealing ring 240 is provided at the connection between the valve core body and the angle valve body 100, which helps to reduce leakage at the connection between the valve core body and the angle valve body 100. The support ring 250 helps to maintain the stability of the first sealing ring 240 and prevent the first sealing ring 240 from falling out of the preset position.

[0047] It should be noted that, in order to limit the first sealing ring 240, a groove can be formed between the angle valve body 100, the first ceramic plate 210 and the valve core rod 230.

[0048] In an optional embodiment, a fixing flange 400 is fixed to one end of the valve core rod 230 away from the second ceramic plate 220, the handwheel 300 is disposed between the fixing flange 400 and the angle valve body 100, and decorative rings 500 are provided on both the handwheel 300 and the fixing flange 400 and the angle valve body 100.

[0049] Specifically, the fixed flange 400 and the valve stem 230 can be connected by threads, and the valve stem 230 and the handwheel 300 can be provided with meshing teeth or other structures that facilitate synchronous rotation of the handwheel 300 and the valve stem 230. Furthermore, since relative rotation may occur between the handwheel 300 and the fixed flange 400 and the angle valve body 100, a decorative ring 500 can be provided to reduce friction between the handwheel 300 and adjacent components.

[0050] In an optional embodiment, a limiting groove is provided in the valve core body 200, and a limiting ring 260 fixed to the second ceramic plate 220 is provided in the limiting groove. The end of the valve core rod 230 near the second ceramic plate 220 is fixedly connected to the limiting ring 260.

[0051] The presence of the limiting groove and the limiting ring 260 helps to limit the ceramic plate and the valve core rod 230 in the axial direction, which helps to maintain the stability of the angle valve structure.

[0052] In an optional embodiment, the outer wall of the valve core rod 230 is provided with a groove, and a retaining ring 600 is provided in the groove to abut against the end of the valve core body 200, which helps to maintain the axial relative fixation between the valve core body 200 and the angle valve body 100.

[0053] In an optional embodiment, a wall-mounted box 700 is also included, wherein the water inlet section 110 is located inside the wall-mounted box 700, and one end of the water outlet section 120 is located inside the wall-mounted box 700, while the other end extends out of the wall-mounted box 700 and is located outside the wall-mounted box 700.

[0054] The installation of a 700mm wall-mounted box helps improve the aesthetics of the angle valve and reduces its exposure.

[0055] In an optional embodiment, the portion of the water outlet section 120 located outside the wall-mounted box 700 is provided with a decorative sleeve 710, and the handwheel 300 is located between the fixed flange 400 and the device sleeve, which helps to improve the aesthetics of the angle valve and reduce the exposure of the angle valve.

[0056] In an optional embodiment, a protective sleeve 720 is provided on the portion of the universal angle valve located outside the wall-mounted box 700;

[0057] Alternatively, a decorative panel 730 may be provided on the water outlet section 120.

[0058] In some implementations, when installing the angle valve, a protective sleeve 720 can be placed over the angle valve, such as... Figure 2 As shown, after the other structures are installed, the protective cover 720 can be removed, and then the decorative panel 730 can be installed, as follows. Figure 3 As shown, this is to prevent dust and other dirt from contaminating the angle valve during installation.

[0059] In an optional embodiment, the wall-mounted box 700 is provided with an installation groove, and a level 800 is installed in the installation groove. The level 800 can indicate the installation direction of the angle valve, so as to facilitate the accurate installation of the angle valve in the designated position.

[0060] This utility model also provides a pipeline system including the universal angle valve described in any of the foregoing embodiments.

[0061] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
