Problems solved by technology
[0003] The main defect of the existing diaphragm type anti-corrosion solenoid valve is that when the valve stem moves up and down through the valve cover under the drive of the iron core, the sealing ring on the valve cover has less lubricating grease, and when the valve stem moves up and down frequently, the grease is easy to It is carried away by the medium, which increases the friction between the valve stem and the sealing ring, resulting in delay or even inability to open the solenoid valve, which seriously affects the service life of the solenoid valve

The invention discloses a diaphragm type anti-corrosion electromagnetic valve with an oil storage structure. The electromagnetic valve comprises a valve body, a valve cover and an electromagnetic control assembly, a valve rod in the electromagnetic control assembly penetrates through the valve cover, then the end of the valve rod movably penetrates through a piston in the valve body, and a cylindrical oil storage base is embedded in the end, away from the valve body, of the valve cover; and the end, away from the valve body, of the oil storage base is provided with an oil storage cavity with one end open, the end, away from the valve body, of the oil storage base is provided with an oil storage cover, the valve rod sequentially penetrates through the oil storage cover, the oil storage cavity and the oil storage base, then the end of the valve rod movably penetrates through the piston, and the oil storage cavity is filled with lubricating grease. The oil storage base is mounted on the valve cover, the oil storage cavity is formed in the oil storage base and filled with lubricating grease, and the valve rod can be in contact with the piston after penetrating through the oil storage cavity so that sufficient lubrication can be guaranteed when the valve rod slides up and down, and friction force between the valve rod and the sealing ring can be effectively reduced; and the service life of the electromagnetic valve is prolonged.
Description
technical field [0001] The invention relates to the field of solenoid valves, in particular to a diaphragm type anti-corrosion solenoid valve with an oil storage structure. Background technique [0002] In the field of solenoid valves, anti-corrosion solenoid valves are used in corrosive environments and occasions with corrosive media, and most of the structures of anti-corrosion solenoid valves are diaphragm type. For the diaphragm type anti-corrosion solenoid valve, the valve stem is currently used as the actuator of the switch at home and abroad. When the solenoid valve coil is energized, under the action of electromagnetic force, the iron core drives the valve stem to move up and down through the valve cover. When the valve stem When the component moves up, the pilot valve port on the piston is opened, the upper chamber of the piston is relieved, the pressure in the upper and lower chambers of the solenoid valve is out of balance, the pressure at the inlet end of the val...
