[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model discloses an ultra-high temperature gate valve. When a rocking wheel is rotated, two palms are in contact with the rocking wheel and two fingers push a vertical plate so that a second clamping block and a first clamping block are meshed with each other. At this time, the rocking wheel can be rotated to open and close the valve. After the opening and closing are completed, the force applied to the vertical plate is released. At this time, if the rocking wheel is rotated by mistake, the rocking wheel rotates on the outer edge of the bearing and does not drive the valve stem to rotate, thereby avoiding loosening or opening and closing of the valve due to mistaken operation of rotating the rocking wheel, thereby avoiding serious consequences and ensuring the stability of the valve. Accidental deflection of the rocking wheel can be avoided, and the water flow of the pipeline can be avoided to be adjusted accidentally, thereby improving the control effect of the ball check valve.

[0022] A spring 12 is movably sleeved on the outer edge of the movable rod 10, and a connecting plate 13 is fixedly connected to one end of the movable rod 10 away from the valve stem 5. The spring 12 is fixedly connected to the fixed plate 11 and the connecting plate 13 respectively, and a fixed rod 14 is fixedly connected to one side of the connecting plate 13 away from the spring 12. Both ends of the fixed rod 14 are fixedly connected to vertical plates 15. The cross-section of the fixed rod 14 is U-shaped, and the U-shaped opening faces downward. The vertical plates 15 are located on the inner side of the rocker 7, and two adjacent vertical plates 15 are symmetrically arranged front to back with the central axis of the fixed rod 14 as the axis of symmetry.

[0023] Working principle: During use, the valve body 1 is connected to the connecting pipe through the flange 2, and the valve body 1 is closed and opened by rotating the rocking wheel 7. When rotating the rocking wheel 7, the two palms are in contact with the rocking wheel 7, and two fingers push the vertical plate 15, so that the vertical plate 15 moves in the direction of the valve stem 5, and the vertical plate 15 drives the fixed rod 14 to move, and the fixed rod 14 drives the connecting plate 13 to move, and the connecting plate 13 drives the movable rod 10 and the second clamping block 9 to move in the direction of the first clamping block 8 until the second clamping block 9 and the first clamping block 8 are engaged with each other. At this time, the rocking wheel 7 can be rotated to open and close the valve. After the opening and closing is completed, the force on the vertical plate 15 is released. At this time, if the rocking wheel 7 is rotated by mistake, the rocking wheel 7 rotates on the outer edge of the bearing 6 and does not drive the valve stem 5 to rotate, thereby avoiding the loosening or opening and closing of the valve due to the rotation of the rocking wheel 7 due to mistaken operation, thereby avoiding serious consequences, ensuring the stability of the valve, thereby avoiding the deflection of the rocking wheel 7 due to accidents, avoiding the accidental adjustment of the water flow of the pipeline, and improving the control effect of the ball check valve.
