SOLENOID VALVE Russian patent published in 2024 - IPC F16K31/05 F16K1/12 

FIELD: valve industry.

SUBSTANCE: invention relates to shut-off valves with pulse electromagnetic control used in safety automation systems of gas heat-and-power plants. Solenoid valve comprises a manual control mechanism for setting the valve in an open state. This mechanism includes a bushing with permanent magnets, a pusher, a fixing ring from ferromagnetic material and a slide valve. When the pusher moves the bushing with permanent magnets, the slide valve, which acts as a shut-off element in the valve, is displaced into the working position when the valve is open. This condition is retained by means of a fixing ring. Automatic closing of the valve is performed by means of an electromagnet forming a magnetic flow, which moves the bushing with permanent magnets and the slide valve to the valve seat.

EFFECT: invention is aimed at reducing the cost of the valve, increasing the flow rate of the working medium through the valve, and improving the tightness of the shut-off element.
