The utility model sets a sliding cylinder and a control hole groove, and the rotation of the working screw drives the sliding guide column to slide synchronously through the threaded slider, so that the sliding guide column slides through the inclined sliding guide groove to drive the sliding orifice plate to slide horizontally, and the sliding orifice plate slides and drives the sliding cylinder to slide along the outer wall of the limit column at one end of the control cylinder, so that the sliding cylinder slides and moves relative to the control hole groove on the outer wall of the control cylinder. By controlling the relative position of the sliding cylinder and the control hole groove, the flow area of ​​the control frame is adjusted to facilitate the adjustment operation, thereby realizing the adjustment operation of the supply water source pressure.
