Technical Field

[0001] The utility model relates to the field of eccentric angle valves, in particular to an eccentric angle valve that can be telescoped and switched on and off. Background Technique

[0002] In various industrial and domestic scenarios, the control and regulation of water flow are crucial. Whether it is the cooling system and cleaning equipment in industrial production, or faucets and shower heads in daily life, reliable water flow control devices are required to ensure the reasonable use of water and the normal operation of the system.

[0003] An eccentric angle valve is a valve used to control the flow of fluids. It mainly realizes the opening and closing function through an eccentric structure. Its design allows for reduced friction during the opening and closing process, extending the service life, and is suitable for occasions where the flow rate and pressure are regulated.

[0004] Currently, there are some problems with existing water flow control devices in practical applications: on the one hand, in traditional water flow control devices, the telescopic function and the adjustment function are often designed separately. This leads to more cumbersome operation in actual use, where telescopic adjustment and flow rate adjustment need to be carried out separately, not only increasing the complexity of operation but also reducing work efficiency. In some scenarios where rapid adjustment of water flow size and pipe length is required, the separate design cannot meet the immediate needs. On the other hand, the filtering effect of existing devices is not good, and it is easy for impurities to enter the system, causing blockage of the regulating valve, thereby affecting the control and regulation of the flow rate. For this reason, an eccentric angle valve that can be telescoped and switched on and off is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an eccentric angle valve that can be telescoped and switched on and off, aiming to improve the problem that the telescopic function and the adjustment function in the existing technology are often designed separately, resulting in more cumbersome operation in actual use.

External threads are provided on the outer wall of the bottom end of the pressing block 6, and internal threads matching the pressing block 6 are provided on the side wall of the top end of the housing 1, so that the whole pressing block 6 can be threadedly installed on the inner wall of the housing 1 to press the position of the internal water inlet plate 7. And hexagonal empty grooves are provided on the surface of the pressing block 6, which facilitates installers to use special tools to rotate and install it. The water inlet plate 7 is detachably installed on the inner wall of the bottom end of the pressing block 6.

[0036] Refer to Figure 5 and Figure 6The inner side wall of the shell 1 penetrates and is rotatably connected with a control block 4, the outer wall of the shell 1 is provided with an arc groove, and the control block 4 is composed of a group of dial blocks and a rotating ring, so that the dial block can be driven to drive its rotating ring and the baffle A8 installed on the inner wall to rotate synchronously, so that the hole positions of the baffle A8 and the baffle B9 can be misaligned, so as to adjust the closing and opening of the water volume, and sealing rings are provided on the upper and lower sides of the inner wall of the shell 1 corresponding to the control block 4, so that the control block 4 can be sealed when rotating, so as to prevent water from seeping out of the rotating gap, the inner wall of the control block 4 is detachably installed with the baffle A8, the bottom end of the outer wall of the water inlet plate 7 is in contact with the top end of the outer wall of the baffle A8, and the inner side wall of the control block 4 is provided with a Positioning groove, the outer wall of baffle A8 is connected to the inner wall of the positioning groove of the control block 4, and the bottom end of the inner wall of the shell 1 is detachably installed with a baffle B9, and the top end of the outer wall of baffle B9 contacts the bottom end of the outer wall of baffle A8. Through the cooperation between baffle A8 and baffle B9, when the control block 4 drives the baffle A8 to rotate, the cavities corresponding to the surfaces of baffle A8 and baffle B9 are aligned or offset and closed, so that the size and closing of the water flow can be adjusted, and the outer wall of baffle B9 contacts the inner wall at the top end of the shell 1, and the inner wall at the bottom end of the shell 1 is provided with a guide groove that fits the baffle B9, and the inner wall at the bottom end of the shell 1 is provided with a sealing ring, so as to prevent water from seeping out from the gap where the baffle B9 and the shell 1 are installed.

[0037] Reference Figure 2 and Figure 3 The filter assembly 5 includes a filter plate 51, and the outer wall of the filter plate 51 is in contact with the inner wall of the shell 1. The contact between the two can position the installation position of the filter plate 51. At the same time, by arranging the filter plate 51 at the top of the shell 1, the water entering the shell 1 can be filtered, thereby avoiding excessive impurities inside, which easily clog the empty grooves of the baffle A8 and the baffle B9, thereby causing the control block 4 to be unable to rotate and adjust the water flow. The inner walls on both sides of the filter plate 51 are elastically connected with wedge blocks 53 through limit springs 52. One end of the limit spring 52 is fixedly connected to the inner wall of the filter plate 51, and the other end of the limit spring 52 is fixedly connected to the outer wall of the wedge block 53. The function of the limit spring 52 is to automatically reset the position of the wedge block 53 after it is pushed outward, and the wedge block 53 is slidably connected to the inner wall of the filter plate 51.

[0038] Reference Figure 3The top of the wedge block 53 is provided with an anti-sliding block, through which the whole can be moved, and the surface of the filter plate 51 is provided with a sliding groove that fits the wedge block 53, and the sliding groove is blocked by the anti-sliding block at the top of the wedge block 53 in the initial state, thereby preventing water from entering.

[0040] When water enters from the top of the shell 1, it is first filtered by the filter plate 51. The outer wall of the filter plate 51 contacts the installation groove of the inner wall of the top of the shell 1 to achieve positioning installation. The inner walls on both sides of the filter plate 51 are elastically connected to the wedge block 53 through the limit spring 52. When the wedge block 53 moves back and forth, its front end can be separated from the slot of the shell 1, so that the filter plate 51 can be disassembled as a whole. On the contrary, two sets of slots are opened on the inner wall of the shell 1, and the wedge block 53 is engaged with the slot to fix the filter plate 51 on the inner wall of the top of the shell 1 to prevent the filter plate 51 from shaking during daily use, ensure that it can filter water normally, and avoid excessive impurities clogging the empty slots of the baffle A8 and the baffle B9, affecting the control block 4 to adjust the water flow.

[0041] The control block 4 is composed of a dial block and a rotating ring. The dial block can be driven to drive the rotating ring and the baffle A8 installed on the inner wall to rotate synchronously, and sealing rings are provided on the upper and lower sides of the inner wall of the shell 1 corresponding to the control block 4 to prevent water seepage in the gap when the control block 4 rotates. A baffle A8 is installed on the inner wall of the control block 4. Through the cooperation of the baffle A8 and the baffle B9, when the control block 4 drives the baffle A8 to rotate, the cavities corresponding to the surfaces of the baffle A8 and the baffle B9 can be aligned or offset and closed, thereby adjusting the water flow rate or closing the water flow. The outer wall of the baffle B9 contacts the inner wall of the top end of the shell 1, and the inner wall of the bottom end of the shell 1 is provided with a guide groove and a sealing ring that fits the baffle B9 to prevent water seepage in the installation gap between the baffle B9 and the shell 1.

[0042] A chute is provided on the inner wall at the bottom end of the pressing block 6, the outer wall of the water inlet plate 7 is in contact with the inner wall of the chute, the convex blocks on both sides of the water inlet plate 7 realize positioning and installation, and the cavity on its surface allows water to enter from the top end of the housing 1 and be discharged through the sliding sleeve 2 from the cavity of the water inlet plate 7. The pressing block 6 is threadedly connected to the inner wall at the top end of the housing 1. The threads on the outer wall at the bottom end of the pressing block 6 and the inner wall at the top end of the housing 1 and the fitting threads on the side wall at the top end of the housing 1 enable the pressing block 6 to be threadedly installed on the inner wall of the housing 1 to press the position of the water inlet plate 7. The hexagonal empty groove on the surface of the pressing block 6 facilitates the installer to rotate and install it using a special tool.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
