Abstract
The utility model discloses a bottom valve, which comprises a body, a valve cover, a pad seat and a valve core. A through hole is formed in the body; a plurality of ribs are formed in the inner wall of the through hole; and a positioning seat is convexedly arranged in the back section of the inner wall of the through hole. The valve cover comprises a fixing sleeve and a filtering net cover; an opening of the filtering net cover is fixedly formed at a shaft end surface of the fixing sleeve; and the fixing sleeve is sealed and screwed on the front section of the body. A penetrating hole is formed at the middle part of the pad seat; and the external circumference of the pad seat is sealed between the body and the valve cover, and is fixedly positioned through the body and the valve cover. The valve core is slidingly connected into the through hole of the body; the external peripheral surface of the valve core is adapted to the inside of the ribs; the front end of the valve core is set as a spherical shape; and the radius of the spherical shape is greater than the radius of the penetrating hole of the pad seat. The bottom valve has the advantages of simple structure and low manufacturing cost.
