At the same time, the medium in the components will flow into the valve shell 9 through the flow pipe 2 16 of the lower valve shell 9 and be discharged through the corresponding flow pipe 15. By pressing the pressure plate 11 in the control cylinder 3, the valve stem 10 will be driven to move downward. When the valve stem 10 moves downward, the two connected valve stems 2 13 and the sealing valve core 14 fixed on the valve stem 2 13 will be driven to move downward and be blocked in the inner lower part of the valve shell 9 respectively, so that the externally connected components perform reverse actions and the medium flows in the reverse direction.

It can be used as a reversing valve or a cut-off valve, and has a simple structure and low maintenance cost. In addition, by rotating the bidirectional screw 5, the corresponding movable plate 17 can be driven to approach or move away at the same time. When maintaining the valve shell 9 in the valve group, the bidirectional screw 5 can be rotated so that the movable plate 17 drives the clamping block 19 to move away at the same time, so that the mounting block 2 can be pulled out of the outer shell 1 as a whole, and then the two outer shells 1 can be disassembled. When installation is required, it is only necessary to abut the two outer shells 1 and put the mounting block 2 on the outer shell 1, and rotate the bidirectional screw 5 in the opposite direction so that the clamping block 19 is stuck in the mounting groove 20, so that the outer shell 1 can be fixed, thereby achieving the effect of facilitating the assembly and disassembly of the device.
