[0001] The utility model relates to the field of the structure of a water heating valve controlled by a pressure sensor, and specifically to a water heating valve structure controlled by a pressure sensor. Background Technique
[0002] The function of a valve in a water heating system is mainly to control and regulate the flow rate, pressure and direction of the fluid in the pipeline to ensure the normal operation of the system. The regulating valve is also called a flow regulating valve or a throttle valve. It can regulate the water pressure by controlling the size and speed of the water flow to achieve the purpose of regulating the pipeline.
[0003] The existing patent CN216131398U discloses a water heating valve. The assembly of the valve core is restricted by the installation part and the installation boss, that is, the valve core and the valve body are assembled into a straight short tubular shape as a whole. After connecting the connecting part at the water inlet to the water heating sanitary ware, most of the requirements of the existing water heating valves can be met by changing the structure at the water outlet of the valve body, reducing the weak parts of the valve body and avoiding the explosion of the valve at the valve core assembly position.

The second wedge plate 204 is slidably connected inside the fixed ring 201. The convex block 402 squeezes the first wedge plate 202 to move towards the inside of the fixed ring 201, so that the convex block 402 pushes the second wedge plate 204 to move outwards. The end of the second wedge plate 204 is fixed with a ring-shaped block plate 203. The outside of the ring-shaped block plate 203 is provided with a rubber sleeve 205. The second wedge plate 204 drives the ring-shaped block plate 203 to move outwards, and the ring-shaped block plate 203 drives the rubber sleeve 205 to move outwards. The top of the fixed ring 201 is slidably connected with a first wedge plate 202. The end of the first wedge plate 202 is in contact with the end of the second wedge plate 204. The outside of the rubber sleeve 205 squeezes the inner wall of the connecting pipe 401 to prevent the internal water from contacting the thread. The middle part of the outside of the valve body 1 is provided with a control part 101. The inside of the control part 101 is provided with a driving rod 102. The middle part of the first wedge plate 202 is arranged outside the fixed ring 201.
[0024] In this embodiment: The screw barrel 304 drives the first wedge-shaped plate 202 in the fixing component 2 to contact the convex block 402 in the connecting pipe 401, causing the convex block 402 to squeeze the first wedge-shaped plate 202 and move it inward into the fixing ring 201. The convex block 402 pushes the second wedge-shaped plate 204 to move outward. The second wedge-shaped plate 204 drives the annular block plate 203 to move outward, and the annular block plate 203 drives the rubber sleeve 205 to move outward, causing the outer side of the rubber sleeve 205 to squeeze against the inner wall of the connecting pipe 401, preventing the internal water from contacting the threads.
[0025] Please refer specifically to Figure 2 、 3 、4. The first connection component 3 is provided with a circular ring 302. Circular rings 302 are fixed to both the top and bottom of the valve body 1. The end of the circular ring 302 is provided with a screw barrel 304 cap 303. The cap 303 is separated from the connection between the screw barrel 304 and the valve body 1. Align the screw barrel 304 with the connecting pipe 401 and rotate the screw barrel 304. The end of the screw barrel 304 is fixedly connected to the fixing ring 201. The head end of the screw barrel 304 is provided with an annular groove 301, and the inside of the annular groove 301 is rotatably connected to the circular ring 302. A nut 303 is provided at the connection between the screw barrel 304 and the outer side of the valve body 1. The screw barrel 304 is rotated into the connecting pipe 401, and then the nut 303 is rotated again to make the nut 303 rotate to the connection between the screw barrel 304 and the valve body 1 for fixation. The outer side of the screw barrel 304 is provided with a second connection component 4. The second connection component 4 includes a connecting pipe 401 and a convex block 402. The screw barrel 304 drives the first wedge-shaped plate 202 in the fixing component 2 to contact the convex block 402 in the connecting pipe 401. The connecting pipe 401 is connected to the outer side of the screw barrel 304, and the convex block 402 is fixed to the inner wall of the screw barrel 304.
[0026] In this embodiment: The nut 303 is separated from the connection between the screw barrel 304 and the valve body 1. Align the screw barrel 304 with the connecting pipe 401 and rotate the screw barrel 304 so that the screw barrel 304 rotates into the connecting pipe 401. Then rotate the nut 303 again to make the nut 303 rotate to the connection between the screw barrel 304 and the valve body 1 for fixation, preventing the loosening of the nut 303. There is no need to rotate the valve body 1 itself, which is convenient for installation.
[0027] Working principle: Rotate the nut 303 to separate the nut 303 from the connection between the screw barrel 304 and the valve body 1. Align the screw barrel 304 with the connecting pipe 401 and rotate the screw barrel 304 so that the screw barrel 304 rotates into the connecting pipe 401. Then rotate the nut 303 again to make the nut 303 rotate to the connection between the screw barrel 304 and the valve body 1 for fixation, preventing the loosening of the nut 303. There is no need to rotate the valve body 1 itself, which is convenient for installation;
[0028] When the screw barrel 304 rotates into the connecting pipe 401, the screw barrel 304 drives the first wedge-shaped plate 202 in the fixing assembly 2 to contact the convex block 402 in the connecting pipe 401, causing the convex block 402 to squeeze the first wedge-shaped plate 202 and move it towards the inside of the fixing ring 201, and the convex block 402 pushes the second wedge-shaped plate 204 to move outwards. The second wedge-shaped plate 204 drives the annular block plate 203 to move outwards, and the annular block plate 203 drives the rubber sleeve 205 to move outwards, so that the outer side of the rubber sleeve 205 squeezes against the inner wall of the connecting pipe 401 to prevent the water inside from contacting the threads.
[0029] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
