ELECTROMAGNETIC VALVE Russian patent published in 2019 - IPC F16K31/02 F16K1/22 F16K11/10 

FIELD: gas industry.

SUBSTANCE: invention relates to the valve industry, namely to valves, and can be used for automatic and manual control and regulation of the flow of gas media in technological systems, as well as in gas-burning devices of thermal units that use gaseous media as fuel. Solenoid valve contains a spring-loaded main valve body, made in the form of a piston with a sealing disc, and an additional valve body connected with it kinematically, with a locking element connected to the electromagnet armature. Inside the inlet and/or outlet channel of the valve body on the axis of rotation there is a rotary damper, the profile of which corresponds to the profile of the internal channel of the valve body.

EFFECT: proposed solenoid valve provides steady control of the flow rate of the gas medium flowing through the valve over the entire valve opening range, unstressed opening of the valve and a gradual increase in pressure in the area after the valve, providing protection for devices and devices sensitive to sudden pressure surges.
