Japanese Patent JP6905146
Kind Code:
B2
Abstract:
A pump body assembly, a pump, a sprinkler system, and an unmanned aerial vehicle are provided. The pump body assembly includes a drainage outlet (1235) on a pump housing (12) and a valve body portion (51) of a valve core member (5). The valve body portion (51) is elastic. The valve body portion (51) changes from a natural state to an elastic deformation state under an action of liquid in the pump housing (12). When the valve body portion (51) is in the natural state, the valve body portion (51) seals the drainage outlet (1235) of the pump housing (12). When the valve body portion (51) is in the elastic deformation state, the valve body portion (51) does not seal the drainage outlet (1235) of the pump housing (12). When a liquid medium leaks due to a broken pipe in a pump body, the liquid medium is discharged from the drainage outlet (1235) via the valve core member (5).
