Abstract

The invention provides a self-holding solenoid valve and relates to a solenoid valve. The self-holding solenoid valve comprises a valve body, a valve element, a sliding connecting rod and an electromagnetic coil, wherein a connecting rod slide way, a piston slide way and a valve cavity are arranged in the valve body; a fluid outlet output is arranged on a wall body of the piston slide way and a fluid inlet input is arranged on a wall body of the valve cavity; the valve element is in a hollow piston structure; a through hole is formed in the side wall of the upper part of the piston structure; an upper sealing ring and a lower sealing ring are arranged on the outer side of the middle wall body of the piston structure and on the outer side of the lower part wall body of the piston structure; an iron magnet is arranged in the upper end body of the sliding connecting rod; the sliding connecting rod is connected with the upper end of the valve element; the valve element is arranged in the piston slide way; the sliding connecting rod stretches into the connecting rod slide way; an isobaric cavity is formed by a piston slide way space above the upper sealing ring; the valve cavity is communicated with the isobaric cavity by a fluid channel and a through hole in the valve element; the electromagnetic coil is mounted at the periphery of the wall body of the connecting rod slide way. According to the self-holding solenoid valve, valve switching-on/off operation can be smoothly carried out without overcoming the pressure of fluid; a valve seat is not arranged in the valve body so that the structure of the solenoid valve is simple.

Description

technical field [0001] The invention relates to an automatically controlled electromagnetic appliance, in particular to an electromagnetic valve. Background technique [0002] Solenoid valves include gas solenoid valves, steam solenoid valves, water solenoid valves, oil solenoid valves and refrigeration solenoid valves. Solenoid valves are widely used in household appliances, textiles, light industry, and urban construction industries as actuators for automatic control of fluid media. . The solenoid valve uses electromagnetic force to act on the iron core sealed in the magnetic sleeve to complete the valve opening action. There is no dynamic seal, so it can avoid leakage. Therefore, the solenoid valve has the characteristics of safe use, especially suitable for corrosive, toxic Or high and low temperature media. [0003] The existing solenoid valve needs a valve seat in the valve body, which has the disadvantages of complex structure, high processing precision and easy clo...
