the embodiment is described below with reference to fig. 1-11, and the sixth embodiment is further described, wherein the limiting mechanism 6 comprises a vertical rod 6-1, a long screw 6-2, a seat plate 6-3, a clamping rod 6-4, a U-shaped frame 6-5 and a cross rod 6-6, the lower end of the vertical rod 6-1 is inserted on a cross rail column 1-5 in a clearance fit manner, a stopper I1-8 is stopped at the outer end of the vertical rod 6-1, the upper end of the vertical rod 6-1 is fixedly connected with the cross rod 6-6, the rear end of the cross rod 6-6 is fixedly connected with the U-shaped frame 6-5, the U-shaped frame 6-5 is inserted on an upper shaft 4-1 between two limiting rings 4-2, the upper end of the vertical rod 6-1 is slidably connected with the clamping rod 6-4, and the rear end of the clamping rod 6-4, the triangular pointed end is clamped on the teeth on the external tooth circular plate 5-1, the back end of the clamping rod 6-4 is fixedly connected with a seat plate 6-3, one end of a long screw 6-2 is inserted on the seat plate 6-3 in a clearance fit mode, and the other end of the long screw 6-2 is connected to the vertical rod 6-1 through threads. The stopper I1-8 is used for preventing the vertical rod 6-1 from sliding down from the transverse rail column 1-5, and when the limiting mechanism 6 needs to be dismounted, the stopper I1-8 is dismounted, so that the vertical rod 6-1 can be dismounted. The U-shaped frame 6-5 is inserted on the upper shaft 4-1 between the two limit rings 4-2, so that the upper shaft 4-1 can be prevented from moving up and down, the rotating shaft 3-1 and the butterfly plate 3-2 can be prevented from moving up and down, and the butterfly plate 3-2 is more stable. When the long screw 6-2 is rotated, the triangular pointed end on the clamping rod 6-4 is clamped on the teeth on the external tooth round plate 5-1, so that the rotation of the external tooth round plate 5-1 can be limited, and the valve is prevented from being flushed open by overlarge water pressure when the valve is closed, and water flow is prevented from leaking.
The working principle of the invention is as follows: the retaining head I1-8 can be sleeved on the transverse rail column 1-5 or taken down from the transverse rail column 1-5, the retaining head I1-8 can be fixed on the transverse rail column 1-5 when the fastening screw I1-6 is screwed to be tightly pressed against the transverse rail column 1-5, and the upper pressing ring 1-3 is used for pressing the upper sealing ring 1-4 to prevent the upper sealing ring 1-4 from moving. When the rotating shaft 3-1 rotates by taking the axis of the rotating shaft as a shaft, the butterfly plate 3-2 can be driven to rotate by taking the axis of the rotating shaft 3-1 as a shaft, so that the opening and closing of the valve are controlled, and the butterfly plate sealing ring 3-3 is used for sealing between the semi-cylindrical shell I1-1 and the butterfly plate 3-2 or between the semi-cylindrical shell II2-1 and the butterfly plate 3-2. The stopper II4-3 can slide on the square column 4-4, the stopper II4-3 and the square column 4-4 can be fixedly connected when the fastening screw II4-5 is screwed to be tightly pressed against the square column 4-4, and the upper shaft 4-1 can drive the rotating shaft 3-1 to rotate by taking the axis of the upper shaft as the axis of the upper shaft. When the rod body 5-3 is pulled to rotate, the square column 4-4 can be driven to rotate, so that the upper shaft 4-1 is driven to rotate by taking the axis of the upper shaft as a shaft, the rotating shaft 3-1 is driven to rotate by taking the axis of the rotating shaft as a shaft, the rotating shaft 3-1 is controlled to rotate, and the opening and closing of the valve are controlled. When the stopper II4-3 is taken down from the square column 4-4, the external tooth round plate 5-1 can be detached from the square column 4-4. The stopper I1-8 is used for preventing the vertical rod 6-1 from sliding down from the transverse rail column 1-5, and when the limiting mechanism 6 needs to be dismounted, the stopper I1-8 is dismounted, so that the vertical rod 6-1 can be dismounted. The U-shaped frame 6-5 is inserted on the upper shaft 4-1 between the two limit rings 4-2, so that the upper shaft 4-1 can be prevented from moving up and down, the rotating shaft 3-1 and the butterfly plate 3-2 can be prevented from moving up and down, and the butterfly plate 3-2 is more stable. When the long screw 6-2 is rotated, the triangular pointed end on the clamping rod 6-4 is clamped on the teeth on the external tooth round plate 5-1, so that the rotation of the external tooth round plate 5-1 can be limited, and the valve is prevented from being flushed open by overlarge water pressure when the valve is closed, and water flow is prevented from leaking.
