DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, this embodiment includes a valve body 1, with liquid inlets 11 and liquid outlets 12 on both sides of the valve body 1, a valve hole 13 on the top of the valve body 1, a valve core 2 is fixed in the valve hole 13, a rectangular groove 21 is formed at the lower end of the valve core 2, and the rectangular groove 21 forms two valve core feet 22 at the lower end of the valve core 1, a valve block 3 is installed inside the valve body 1, the valve block 3 is installed at the bottom of the valve hole 13, the valve block 3 can rotate along the inner wall of the valve hole 13, the valve block 3 and the inner wall of the valve body 1 form two placement grooves 14, the two valve core feet 22 are respectively installed in the two placement grooves 14, so that the top of the rectangular groove 21 fits with the top of the valve block 3, and the valve core 2 The rotation can drive the valve block 3 to rotate. A valve wrench 4 is fixedly mounted on the upper end of the valve core 2. Rotating the valve wrench 4 can rotate the valve core 2. A longitudinal through hole 23 is provided in the center of the valve core 2. The screw 5 is connected to the valve core 2 through the through hole 23.
