Abstract

The invention discloses a novel swing check valve, relating to a check valve. The novel swing check valve consists of a valve cap (1), a hinge pin (2), a rocking bar (3), a valve clack (4), a valve body (5) and an auxiliary valve (6), wherein the valve cap (1) is arranged on the upper end of the valve body (5), the hinge pin (2) is arranged on the upper end of the interior of the valve body (5), the rocking bar (3) is connected with the hinge pin (2), the auxiliary valve (6) is arranged on the lower side of the valve clack (4), and the valve clack (4) is connected with the rocking bar (3). The auxiliary valve is additionally arranged, thus the novel swing check valve has the advantages that the water hammer which damages a pipeline system and is caused by the traditional similar check valve is solved; the use range of the check valve is expanded; and the novel swing check valve is convenient to use.

Description

Technical field: [0001] The invention relates to a check valve, in particular to a novel swing check valve. Background technique: [0002] The check valve is an automatic valve that prevents the medium in the pipeline from flowing backwards, and the bottom valve of the water pump suction valve also belongs to the check valve category. Its opening and closing parts are opened or closed by the medium flow and force to prevent the medium from flowing backward. The check valve belongs to the automatic valve category. As a valve that opens when the pipeline system flows downstream and closes when it flows upstream, it is mainly used to prevent the reverse flow of the medium, the reversal of the pump and the drive motor, and the discharge of the medium in the container; The swing check valve whose disc rotates around the pin axis of the valve body and the lift check valve whose disc moves along the vertical centerline of the valve body, but the valves of the above two structures ...
