Pneumatic type flushing valve

Abstract

Disclosed is a pneumatic type flushing valve. The pneumatic type flushing valve comprises a valve seat, a valve body, an overflow tube, a valve core, a full-drainage floater, a half-drainage floater,air pumps, a full-drainage executing device, a half-drainage executing device, a full-drainage pulling unit, a half-drainage pulling unit and a base; the lower end of the valve body is inserted into an adapter of the base, and the base supports the valve body; the overflow tube penetrates through and is slidingly matched with a sleeve; the full-drainage driving sleeve of the full-drainage pullingunit is slidingly matched with the base of a full-drainage sleeve, and the half-drainage sliding sleeve of the half-drainage pulling unit is slidingly matched with the sliding unit of a half-drainagesleeve; the full-drainage executing device is arranged on a full-drainage executing bae and the matched with a full-drainage driving arm, and the half-drainage executing device is arranged on a half-drainage executing base and matched with a half-drainage driving arm; the full-drainage pulling unit and the half-drainage pulling unit move the overflow tube, one of the air pumps is communicated withthe full-drainage executing device, and the other air pump is communicated with the half-drainage executing device. By means of the structure, the air pumps serve as power output units and accordingly are rapid in motion, low in noise and wearing and long in service life.

Description

technical field [0001] The invention relates to a flushing valve for a toilet flushing tank. Background technique [0002] In the current prior art, a flush valve includes a valve seat, a valve body, an overflow pipe, a valve core, a full row of floats, a half row of floats and a pressing plate assembly, and the valve seat is provided with a valve core seat, a water inlet hole and a water outlet interface. , the valve body includes a full row valve body located at the lower part and a half row valve body located at the upper part; the valve core is set at the lower end of the overflow pipe; the lower end of the valve body is connected to the valve seat, the overflow pipe is slidingly fitted with the sleeve, and the valve core Cooperating with the valve core seat, the full and half rows of buoys are respectively located in the full and half valve body and move with the overflow pipe respectively; the pressing plate assembly drives the full and half row of buoys through the tr...
