The invention discloses an electromagnetic directional valve for a ship. The electromagnetic directional valve for the ship comprises side covers, armatures, coils, a valve body, oil holes, sealing rings, valve elements, push rods, plugs, plug assemblies, springs, oil cavities and check rings. The two side covers are installed on the two sides of the valve body respectively. The oil cavities are formed in the valve body. The four oil holes are formed in the valve body. The sealing rings are installed on the outer edges of the oil holes. Hydraulic oil pipes can be installed on the oil holes, and the sealing rings have the sealing function. The valve elements are installed in the oil cavities. The two push rods are welded to one side of one valve element and one side of the other valve element respectively. The check rings are installed between the push rods and the valve body and have the sealing function. Each spring is installed on the corresponding push rod. The coils are fixedly installed in the side covers. The armatures are installed on the coils. One ends of the armatures are connected with the push rods. The plug assemblies are installed on the outer faces of the side covers. External wires can be connected to the coils through the plug assemblies. The coils are electrified so that the armatures can move. The plugs are installed on the end faces of the side covers and are made of rubber.
Description
technical field [0001] The invention relates to a marine electromagnetic reversing valve, which belongs to the field of marine engineering. Background technique [0002] There is a closed chamber in the electromagnetic reversing valve, and there are through holes in different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the chamber, and two electromagnets on both sides. To which side, different oil discharge holes are opened or closed by controlling the movement of the valve body, while the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then the piston of the cylinder is pushed by the pressure of the oil, The piston drives the piston rod, and the piston rod drives the mechanical device. The electromagnetic reversing valve itself has a simple structure and low price, and is easier to install and maintain than other types of actuators. What's more remarkable is that the compose...
