Abstract
A water-shutoff and discharge control apparatus for use of sprinkling comprises a valve body and a rotary sleeve. The valve body has a water-enclosed surface disposed therein to divide a water-intake chamber and a water-outlet chamber, and a curved-extending positioning groove indented at the periphery thereon for the accommodation of a watertight hoop. Outlet and inlet orifices are provided to fluidly connect to the water-intake chamber and the water-outlet chamber respectively. The rotary sleeve, mounted to the valve body and sealed watertight thereto at both ends, has a water-sealing area and water-outlet ducts disposed therein to match to the curved line of the watertight hoop, permitting the water-sealing area to completely abut against the watertight hoop. Therefore, the rotary sleeve is simply rotated to shift the positions of the water-sealing area and the water-outlet ducts gradually switching from the watertight hoop for easy control of water shutoff and discharge thereby.
