After opening the cover plate 2, the inside of the device can be inspected and operated. After that, the cover plate 2 is closed, and the closing screw 5 can be turned to improve the tightness of the connection of the cover plate 2. The clamping block 3 can be clamped into the buckle 4 for use, thereby achieving the effect of improving the inspection and maintenance efficiency, avoiding the situation that the maintenance personnel open the device when inspecting the inside of the device, which is very cumbersome and easy to cause damage to the device, thereby delaying the inspection and maintenance efficiency.

[0027] The top of the cover plate 2 is fixedly connected with a reversing assembly, which includes a fixed plate 6, a rotating rod 7, a rotating hand 8, a connecting rope 9 and a reversing plate 10. The bottom of the fixed plate 6 is fixedly connected to the top of the cover plate 2. The inside of the fixed plate 6 is rotatably connected with the rotating rod 7. One end of the rotating rod 7 is fixedly connected to the rotating hand 8. The outer surface of the rotating rod 7 is sleeved with a connecting rope 9. One end of the connecting rope 9 is fixedly connected to the reversing plate 10. When reversing is required, the operator can rotate the rotating hand 8 to drive the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the connecting rope 9 to extend and retract. The extension and retraction of the connecting rope 9 drives the reversing plate 10 to lift or lower, thereby achieving the effect of improving the fluid reversing efficiency, avoiding the situation that it is difficult for general valves to adjust the flow direction of the fluid, resulting in limitations of the device and being unfavorable for use;

[0028] In this embodiment, preferably, the reversing assembly further includes a limit block 11, and one end of the rotating rod 7 away from the rotating handle 8 is fixedly connected to the limit block 11, and the limit block 11 is set to prevent the position of the rotating rod 7 from being offset when the rotating rod 7 rotates, thereby limiting the rotating rod 7;

After opening the cover plate 2, the inside of the device can be inspected and other operations can be performed. Then the cover plate 2 is closed and the closing screw 5 is rotated to improve the tightness of the connection of the cover plate 2. The card block 3 is inserted into the buckle 4 and the valve can be used, thereby achieving the effect of improving the inspection and maintenance efficiency, avoiding the situation that the maintenance personnel open the device when inspecting the inside of the device. The process is very cumbersome and easy to cause damage to the device, which leads to delays in the inspection and maintenance efficiency. When reversing is required, the operator can turn the handle 8 to drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 drives the connecting rope 9 to extend and retract, and the extension and retraction of the connecting rope 9 drives the reversing plate 10 to lift. Or lower it, so as to achieve the fluid reversing effect, avoid the situation that the general valve is difficult to adjust the fluid flow direction, resulting in the device having limitations and being unfavorable for use.
