[0025] A mounting box 2 is provided on one side of the valve body 3, and two card slots 9 and a mounting frame 14 are provided inside the mounting box 2. The mounting frame 14 is installed on the card slot 9, and a foreign matter filter 5 is provided on the surface of the mounting frame 14. A sealing gasket 8 is provided on the bottom surface of the mounting frame 14. When in use, the mounting frame 14 is installed on the card slot 9 by means of a handle 1, and the mounting frame 14 is installed on the mounting box 2 with four bolts. After installation, water flowing into the valve body 3 from the inlet will be intercepted by the foreign matter filter 5 on the upper surfaces of the two mounting frames 14, and foreign matter will be blocked outside the valve body 3 to prevent foreign matter from entering the valve body 3 and clogging the valve, and the sealing gasket 8 on the bottom surface of the valve body 3 will prevent water from overflowing the mounting box 2.

When it is set, the hand wheels 6 on the two valves can be rotated at the same time. Affected by the guide pin 7 in the spiral groove 17 of the valve stem 10, the valve core 12 begins to rise and rotate until it is fully open. When closing, the operation is reversed. Setting two valves can still work when one of the valves is damaged.
