Abstract

The invention relates to the technical field of marine valves, in particular to a side valve. The side valve comprises a valve body, a valve clack, a balance cavity piston, a valve rod, a valve coverand a hydraulic driving mechanism; the valve body is of a hollow structure, the valve clack and the balance cavity piston are all arranged inside the valve body, the balance piston is located in a cylindrical cavity in the middle of the valve body, and one end of the valve rod extends into the valve body to be connected with the valve clack; and the valve cover is arranged on one end of the valvebody in a covering mode, and the hydraulic driving mechanism is connected with the valve rod. The valve rod is driven by the hydraulic driving mechanism so that opening and closing of a main sealing surface between the valve body and the valve clack can be realized, and remote manipulation of the side valve can be realized; and manual on-site manipulation of the side valve is not need, and the working intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of marine valves, in particular to a side valve. Background technique [0002] The side valve is a valve applied to the side part of the pipeline passing through the hull, and it is also the first block for the connection between the pipeline in the cabin and the outboard. The medium circulating in the sea valve is usually fresh water, sea water, sewage and dirty oil . [0003] The existing side valves can only be manually operated on site, and the degree of automation is low. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a side valve which overcomes the above problems or at least partly solves the above problems. [0005] An embodiment of the present invention provides a side valve, including a valve body, a valve disc, a balance cavity piston, a valve stem, a valve cover and a hydraulic drive mechanism; [0006] The valve body is a hollo...
