Spherical check valve with high opening and closing efficiency

Abstract

The invention discloses a spherical check valve with high opening and closing efficiency, and belongs to the technical field of check valves. The spherical check valve with high opening and closing efficiency comprises a valve body, a circulating part and a flow dividing part, wherein the valve body comprises a first valve body, a second valve body and a ball body; the first valve body and the second valve body are fixed in a crossed manner; the first valve body communicates with the interior of the second valve body; the ball body is located in the second valve body and can slide up and downin the axis direction of the second valve body, and the diameter of the ball body is greater than the inner diameter of the first valve body; the circulating part is arranged between the second valvebody and the first valve body; the first valve body and the second valve body both communicate with the circulating part; and the circulating part is used for providing water flow impact force for theball body when water flow flows reversely, so that the ball body can return quickly, and quick closing of the valve body is achieved. Through the arrangement of the flow dividing part and the circulating part, the movement of the ball body in the opening and closing process of the valve body is accelerated, so that quick opening and closing of the valve body are achieved.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a spherical check valve with high opening and closing efficiency. Background technique [0002] The ball check valve is a valve structure widely used in the pipeline system. It is generally composed of a valve body, a valve seat and a ball. The ball is movable in the valve body and uses its own gravity to form a sealing contact with the valve seat. When the valve body is filled with water, the ball is out of contact with the valve seat under the action of water flow pressure, that is, the ball check valve is opened to pass water; Sealing contact, i.e. the ball check valve is closed. [0003] However, during the use of the existing spherical check valve, it takes a certain amount of time to react by relying on the water flow to push the ball away from the valve seat and relying on the gravity of the ball itself to make the ball come into contact with the valve seat again, re...
