Connecting pipes 2 are connected to both ends of the valve housing 1. A valve body 3 is arranged inside the valve housing 1. A positioning plate 302 is fixed to the top of the valve body 3, and four groups of first jacks 303 are fixed to the edge of the positioning plate 302;

[0025] Specifically, as Figure 2 , Figure 4 and Figure 5 shown, four groups of insertion rods 5 are arranged on the positioning ring 4, and a rotating ring 501 is arranged at the connection between the insertion rod 5 and the positioning ring 4. Second jacks 403 are opened at the connections between the positioning ring 4, the rotating ring 501, and the insertion rod 5. The insertion rod 5 is rotatably connected to the positioning ring 4. The four groups of arranged insertion rods 5 can rotate and be connected to the first jacks 303 of the positioning plate 302, so as to fix the position of the positioning plate 302 and fix the position of the valve body 3 inside the valve housing 1;

[0026] The positions of the four groups of insertion rods 5 on the positioning ring 4 correspond to the positions of the first jacks 303 on the positioning plate 302, and the insertion rod 5 penetrates through the top of the valve housing 1 and is inserted and connected to the first jack 303, so that the insertion rod 5 can be connected to the first jack 303 of the positioning plate 302, facilitating the fixation of the position of the positioning plate 302.

[0027] Embodiment 2, specifically, as Figure 2 , Figure 3 and Figure 5As shown in the figure, a positioning rod 101 with a tubular structure is provided at the top of the valve housing 1. The surface of the positioning rod 101 is provided with a threaded structure, and four groups of limiting chutes 102 are provided on the surface of the positioning rod 101. The provided positioning rod 101 can allow the positioning ring 4 to move on it and adjust the position of the insertion rod 5, facilitating the control of the connection between the insertion rod 5 and the first jack 303 of the positioning plate 302;

[0028] A rotating rod 301 is rotatably connected inside the positioning rod 101. The lower end of the rotating rod 301 is fixedly connected to the valve body 3. A positioning ring 4 is rotatably connected to the outer side of the positioning rod 101. A connecting ring 401 with an annular structure is provided on the inner side of the positioning ring 4 close to the positioning rod 101. Four groups of limiting sliders 402 are fixed on the inner side of the connecting ring 401 close to the positioning rod 101. The provided limiting sliders 402 can prevent the positioning ring 4 from rotating on the positioning rod 101, enabling the connecting ring 401 to move up and down on the positioning rod 101;

[0029] Specifically, as Figure 2 、 Figure 4 and Figure 5 shown, a limiting ring 404 with an "L"-shaped cross-section is fixed to the top of the connecting ring 401.

The setting of the limiting slider 402 can prevent the connecting ring 401 from rotating when the adjusting ring 405 rotates to drive the connecting ring 401 to move upward, making the height adjustment of the connecting ring 401 more convenient.

[0032] When the embodiment of the present application is in use: By providing a positioning plate 302 with a first jack 303 on the valve body 3, after the valve body 3 is rotated by the rotating rod 301 to open or close the valve housing 1, the outer adjusting ring 405 can be rotated. When the adjusting ring 405 rotates, the connecting ring 401 can be driven to move downward by the limiting ring 404. After the connecting ring 401 moves downward, the positioning ring 4 can be driven to move. Finally, the insertion rod 5 on the positioning ring 4 will be inserted into the first jack 303 of the positioning plate 302 to fix the position of the positioning plate 302, so that the valve body 3 can be fixed for the second time to avoid accidentally touching the rotating rod 301 and causing the valve body 3 to rotate.
