Embodiment Construction
[0009] The present embodiment will be further described below with reference to the embodiments of the accompanying drawings.
[0010] As shown in the figure, the valve body 1 is equipped with a valve disc 2, and the valve body 1 is connected with the valve cover 3 by bolts. The valve disc is disc-shaped and rotates around the hinge placed outside the valve seat. When the medium flows, the valve disc automatically opens. When the medium stops flowing, the valve flap is automatically sealed on the valve seat to prevent the backflow of the medium.

A swing check valve is composed of a valve body, a valve clack and a valve cover. The swing check valve is characterized in that the valve clack is arranged in the valve body, the valve clack is in adisc shape, a hinge surrounding a valve seat rotates, and the valve body is connected with the valve cover through bolts. The flowing direction of media is consistent with the swing direction of the valve clack. When the media flow, the valve clack is automatically opened through medium pressure impact, and when the media stop flowing, the valve clack is automatically sealed on the valve seat through the pressure of the media in a pipeline to prevent backflow of the media.
Description
Technical field: [0001] The invention relates to the field of flow control of fluid pipelines, in particular to a liquid control valve. Background technique: [0002] At present, the valves designed and produced in the society are all opened and closed manually, and their disadvantage is that they cannot be opened and closed automatically. Invention content: [0003] In order to solve the problem that the opening and closing of common valves are manually operated manually, the present invention invents a valve that automatically seals the valve to prevent the flow of the medium. [0004] The technical scheme of the present invention is that a swing check valve includes a valve body, a valve cover, and a valve disc. In addition, the valve disc is in the shape of a disc, which is rotated around a hinge placed outside the valve seat. The valve is a valve that automatically seals against the flow of the medium by the valve flap. [0005] The valve disc is installed on the va...
