It is equipped with movable valve plug 5, regulating device in the adjusting chamber 2, the junction of the valve body 1 and movable valve plug 5 is equipped with sealing rubber
Glue-line, the liquid for preventing movable valve plug 5 from making liquid stream cavity 3 during the motion flow into adjusting cavity room 2.
The movable valve plug 5 includes the piston end 7 and tube body 8 being fixedly connected from top to bottom, and the piston end 7 uses
Elastomeric material and the upper end and the composition of water inlet 6 abut against cooperation, for completely cutting off water inlet 6 and liquid stream cavity 3, the piston
7 lower ends and 3 bottom wall of liquid stream cavity are held to constitute limit cooperation, the tube body 8 can be slided up and down relative to valve body 1 and is socketed outside
There are thrust spring 10 and adjustable plate 4, the upper end of tube body 8 is equipped with multiple radial through-hole 9, and multiple radial through-hole 9 are connected to
The flow-guiding channel being equipped in tube body 8, the flow-guiding channel lower end are equipped with water outlet, 10 upper end of thrust spring and tube body
8 compositions of annular flange 11 being equipped with abut against cooperation, and lower end and the composition of adjustable plate 4 abut against cooperation, and the thrust spring 10 is used for
Upward elastic acting force is generated to movable valve plug 5.Described 4 one end of adjustable plate passes through the opening and fixation for adjusting that chamber 2 is equipped with
Vertical rack gear 12 is connected, the vertical rack gear 12 constitutes sliding cooperation with the track groove that valve body 1 is equipped with.
15 mechanism of ratchet includes driving wheel and pawl 16, and the driving wheel includes transmission shaft 13 and is respectively fixedly connected with
The gear 14 and ratchet 15 at 13 both ends of transmission shaft, the transmission shaft 13 are installed on valve body 1 equipped on bearing and can be with respect to valve body 1
Rotation, the gear 14 constitute the handler for engaging cooperation and being equipped with protrusion on the outside of it with vertical rack gear 12, and user can lead to
