Touch type water-saving valve

A light-touch water-saving valve of the invention uses the conversion of steel balls for various controls. First, a shifting steel ball are used to transfer the transverse shear force of a guide plate into the longitudinal thrust to open and close the valve, and then a constant-flow steel ball is used to clamp a valve seat to fix the valve to achieve a constant flow control. When a user releases a brake rod, the valve is automatically closed by a restoration spring. At the same time, the shifting steel ball is pressed by a packing spring, and then the ball grooves on the two sides of the guide plate are pressed to lock the valve to a normally opening operation.
