Abstract

The invention discloses a check valve. The check valve comprises a valve body, a valve cover and a check component fixed into the valve body. The check component comprises a flexible piece and a body, the valve body is provided with a water inlet and a water outlet, and the body gradually shrinks from the water inlet to the water outlet; the flexible piece is in a ring shape, one end of the flexible piece is fixedly connected with the valve body, and the inner wall of the other end of the flexible piece is tightly attached to the side wall of the body; the outer wall of the flexible piece is in smoothing transition to the side wall of the body, and the side wall of the body is a conical curve face protruding outwards; the water inlet of the valve body is connected with a filtering pipe and a connecting opening with the inner diameter larger than the outer diameter of the filtering pipe; and the filtering pipe is located in an inner cavity of the connecting opening, and the filtering pipe is provided with a pipe body with the closed outer end. The check valve is simple in structure, large in positive circulation area, good in reverse sealing performance and free of collision and noise during sealing and has the filtering function.

Description

Technical field [0001] The invention relates to a valve, specifically a check valve. Background technique [0002] An anti-drip check valve is usually installed at the front end of a metering water meter to realize the function of measuring when there is water flow and not measuring when there is no water flow. [0003] The patent number is: ZL200720111885.8 "an energy-saving induction anti-drip valve" patent document discloses an energy-saving induction anti-drip valve, including a valve body, a valve cover and a valve core, the valve core includes a fixed connection on the valve body The valve core body of the valve core body is a cylindrical structure, the opening on the valve core body is connected with the water inlet, the bottom side wall of the valve core body is provided with a hole communicating with the water outlet, and the valve core body is provided with a slide that can slide up and down. Block, the side wall of the slider is provided with a communication hole corres...
