Abstract
The invention provides a piston type control valve which comprises a valve body with a water inlet and a water outlet, a driving mechanism installed in an inner cavity of the valve body and a mouse cage driven by the driving mechanism. The mouse cage axially moves along the piston type control valve among three positions including the water outlet of the valve body, the position between the water outlet of the valve body and the driving mechanism and the driving mechanism. The piston type control valve can achieve energy removing and pressure reducing effects of high energy water flow in small flow when the valve is switched from the closing state to the full opening state of water flow jet holes or water flow channels of the mouse cage, and can achieve the effect that valve water head is minimum in energy loss by delivering designed flow when the valve is switched from the full opening state of water flow jet holes or water flow channels of the mouse cage to the full opening state of the piston-type control valve.
