[0029] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0030] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed during use, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0031] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0032] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0033] An embodiment of the present invention provides a universal angle valve, as Figures 1-3 shown, which includes an angle valve body 100 and a valve core. The angle valve body 100 includes a water inlet section 110 and a water outlet section 120. An included angle is provided between the axes of the water inlet section 110 and the water outlet section 120. The valve stem 230 of the valve core is coaxially arranged with the water outlet section 120;

[0034] One end of the valve core where the valve stem 230 is provided is connected to the water outlet section 120, and the other end is connected with a water outlet joint 130;

[0035] A handwheel 300 for adjusting the valve core to conduct or disconnect the water outlet section 120 is sleeved on the part of the valve core located outside the water outlet section 120.

[0036] In this application, the handwheel 300 is sleeved outside the core valve, and the core valve, the water outlet joint 130 and the handwheel 300 are coaxially arranged. Compared with the handwheel 300 being arranged on one side of the core valve, the restriction on the installation direction of the angle valve in this application is smaller. The angle valve can rotate around the water inlet section 110 as the axis to flexibly select its installation direction, realizing "universal", which is beneficial to adjusting the installation direction of the angle valve according to environmental needs to avoid other facilities or make reasonable use of space.

[0037] Specifically, in this application, the angle valve body 100 can be made of metal material, or plastic material such as PPR material can be used to reduce the use of metal material; the included angle between the axes of the water inlet section 110 and the water outlet section 120 is usually 90°. In some other special application scenarios, according to actual needs, the included angle between the axes of the water inlet section 110 and the water outlet section 120 can also be not 90°.

[0038] In an alternative embodiment, the valve core includes a valve core body 200 fixed to the angle valve body 100. A first ceramic sheet 210 and a second ceramic sheet 220 are disposed within the valve core body 200. A first channel is provided on the first ceramic sheet 210, and a second channel is provided on the second ceramic sheet 220. The second ceramic sheet 220 is fixedly connected to a valve core rod 230 for controlling the rotation of the second ceramic sheet 220 to adjust the overlapping degree of the first channel and the second channel. The handwheel 300 is disposed on the valve core rod 230 and fixedly connected to the valve core rod 230.

[0039] Specifically, the valve core rod 230 is fixedly connected to the second ceramic sheet 220. The valve core rod 230 can rotate self - driven under the drive of the handwheel 300, thereby driving the second ceramic sheet 220 to rotate. When the second ceramic sheet 220 rotates to a specified position, the overlapping area between the first channel and the second channel is the largest, and at this time, the universal angle valve reaches the maximum opening degree. Continuing to rotate the handwheel 300, the second ceramic sheet 220 continues to rotate, and the overlapping area between the first channel and the second channel gradually decreases until the overlapping area between the first channel and the second channel becomes 0, at which time the universal angle valve closes.

[0040] 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 therebetween.

[0041] In some embodiments, one end of the water outlet joint 130 is inserted into the valve core rod 230, and a snap ring 600 is provided between the water outlet joint 130 and the valve core rod 230 to achieve the fixation of the valve core rod 230 and the water outlet joint 130.

[0042] In some embodiments, when the angle valve body 100 is made of PPR material, at this time, in order to stably connect the angle valve body 100 and the valve core body 200, an insert can be provided within the angle valve body 100. The insert and the valve core body can be connected by threads, and at the same time, a sealing ring is provided between the insert and the valve core body.

[0043] In an alternative 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 disposed on the side of the first ceramic sheet 210 away from the second ceramic sheet 220. A support groove is provided inside the first sealing ring 240, and a support ring 250 for pressing the first sealing ring 240 against the inner wall of the valve core body is provided within the support groove.

[0044] Providing the first sealing ring 240 at the connection between the valve core body and the angle valve body 100 is conducive to reducing leakage at the connection between the valve core body and the angle valve body 100. The provision of the support ring 250 is conducive to maintaining the stability of the first sealing ring 240 and preventing the first sealing ring 240 from deviating from the preset position.

[0045] It should be noted that in order to limit the first sealing ring 240, a groove can be formed among the angle valve body 100, the first ceramic sheet 210 and the valve core rod 230.

[0046] In an alternative embodiment, a fixed flange 400 is fixed to one end of the valve core rod 230 away from the second ceramic sheet 220. The handwheel 300 is disposed between the fixed flange 400 and the angle valve body 100, and decorative rings 500 are disposed at positions where the handwheel 300 is close to the fixed flange 400 and the angle valve body 100.

[0047] Specifically, a threaded connection can be adopted between the fixed flange 400 and the valve core rod 230, and meshing teeth or other structures capable of facilitating the synchronous rotation of the handwheel 300 and the valve core rod 230 can be provided between the valve core rod 230 and the handwheel 300. In addition, since relative rotation may occur between the handwheel 300 and the fixed flange 400 and the angle valve body 100, the decorative rings 500 can be provided to reduce the friction between the handwheel 300 and the adjacent components.

[0048] In an alternative embodiment, a limiting groove is provided in the valve core body 200, and a limiting ring 260 fixed to the second ceramic sheet 220 is provided in the limiting groove. One end of the valve core rod 230 close to the second ceramic sheet 220 is fixedly connected to the limiting ring 260.

[0049] The presence of the limiting groove and the limiting ring 260 is beneficial to axially limit the ceramic sheet and the valve core rod 230, and is beneficial to maintaining the stability of the angle valve structure.

[0050] In an alternative embodiment, a clamping groove is provided on the outer wall of the valve core rod 230, and a clamping ring 600 capable of abutting against the end of the valve core body 200 is provided in the clamping groove, which is beneficial to maintaining the relative fixation in the axial direction between the valve core body 200 and the angle valve body 100.

[0051] In an alternative embodiment, a wall-embedded box 700 is further included. The water inlet section 110 is located in the wall-embedded box 700, and one end of the water outlet section 120 is located in the wall-embedded box 700 and the other end passes through the wall-embedded box 700 and is located outside the wall-embedded box 700.

[0052] The provision of the wall-embedded box 700 is beneficial to improving the aesthetic appearance of the angle valve and reducing the exposure of the angle valve.

[0053] In an alternative embodiment, a decorative sleeve 710 is provided on the part of the water outlet section 120 located outside the wall-embedded box 700. The handwheel 300 is disposed between the fixed flange 400 and the device sleeve, which is beneficial to improving the aesthetic appearance of the angle valve and reducing the exposure of the angle valve.

[0054] In an alternative embodiment, a protective sleeve 720 is provided over the portion of the universal angle valve located outside the wall-embedded box 700;

[0055] Alternatively, a decorative panel 730 is provided on the water outlet section 120.

[0056] In some embodiments, when installing the angle valve, the protective sleeve 720 can be placed over the angle valve. As Figure 2 shown, after the installation of other structures is completed, the protective sleeve 720 can be removed, and then the decorative panel 730 can be installed. As Figure 3 shown, this can prevent the angle valve from being contaminated by dust and other dirt during the installation process.

[0057] In an alternative embodiment, an installation groove is provided on the wall-embedded box 700, and a spirit level 800 is installed in the installation groove. The spirit level 800 can indicate the installation direction of the angle valve, facilitating the accurate installation of the angle valve at a specified position.

[0058] An embodiment of the present invention further provides a pipeline system, including the universal angle valve according to any one of the foregoing embodiments.

[0059] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
