Since the plug valve is suitable for frequent operation, the opening and closing is quick and light. The fluid resistance is small. The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance. It has good sealing performance and is not restricted by the installation direction. However, the large opening and closing torque is a major obstacle to the development of it. Being able to solve it will be a good choice for similar valves.

The design is: when opening, the hand wheel rotates clockwise to move the valve stem and the cock axially upward, the purpose is to make a gap between the cock and the valve seat, and the valve stem and the cock stop moving axially upward when the hand wheel continues to rotate clockwise. Rotate to the open position in synchronization with the handwheel for easy opening. When closed, the handwheel rotates counterclockwise to drive the valve stem and the cock to rotate to the closed position. When the handwheel continues to rotate, the valve stem and the cock stop rotating but move axially downward until the cock and the seat reach a reliable seal. Easy to close the end. The ingenious and simple design of the design allows the cock to rotate and the upper and lower steps by rotating only by hand. It is a new type of labor-saving plug valve.
