The fixed portion is has an inlet waterway, a first and second outlet waterway and a control hole that can connect to the outlet waterways. The first outlet waterway has a first outlet and the second outlet waterway has a second outlet. The valve spool is slidably assembled inside the fixed portion vertically to the inlet waterway, and has a slim hole connected to the inlet waterway. The valve spool and the fixed portion form a pressure cavity. The control hole and the slim hole are connected to the pressure cavity. The pressure cavity is controlled by the control hole to drive the valve spool to move along the inlet waterway to close the first or second outlet, switching the inlet waterway to connect to the first or second outlet waterway.
