Description

Technical Field

[0001] The utility model relates to the technical field of reversing valves, in particular to a manual reversing valve. Background Art

[0002] The traditional manual reversing valve is a switch-type structure. By turning the operating handle, the reversing valve core can be switched back and forth between the left, middle and right positions, thereby switching the direction of the hydraulic oil circuit. However, since the operating handle cannot drive the valve core to move continuously, continuous adjustment of the hydraulic flow cannot be achieved, and it does not have a proportional adjustment function. One reversing valve can control one pipeline, so the control effect is poor and it is inconvenient to use. Utility Model Content
