Abstract

The sea water hydraulic electrically controlled one-way valve includes: sea water electromagnet with magnetic core barrel connected with holed end cap and no-hole end cap separately on two ends; magnetic core tube assembly with armature push rod extending beyond the assembly; winding assembly outside the magnetic core tube assembly and with casing, end cap and sealing rings; one-way valve with valve body, which has oil port A, throttle hole, valve core and jump ring, oil port B and oil hole; and armature push rod capable of contacting with the small end of the valve core. The present invention may be used as common one-way valve and can realize back flow under control of signal.

Description

technical field [0001] The invention relates to a directional control valve in the technical field of fluid transmission, in particular to a seawater hydraulic electric control check valve. Background technique [0002] Directional control valves in the field of fluid transmission include check valves, hydraulic control check valves, electromagnetic directional valves, electro-hydraulic directional valves and other types. Check valve, also known as check valve or check valve, has two oil ports in its structure, and its function is to allow fluid to pass in only one direction, but not reverse flow. The check valve is usually used as a pressure maintaining valve, or placed at the outlet of the pump to prevent damage to the pump when the pressure suddenly rises, and it can also be used as a back pressure valve. The hydraulic control check valve is to increase the hydraulic control part on the ordinary check valve. There are three oil ports in the structure. The added oil port ...
