SHUT-OFF GAS VALVE WITH ELECTROMAGNETIC CONTROL Russian patent published in 2017 - IPC F16K31/02 

FIELD: electricity.

SUBSTANCE: shut-off gas valve with electromagnetic control contains a cylindrical frame with a locking ring, a shut-off device made in the form of a gate with a gasket, an inlet branch pipe and an outlet branch pipe with a saddle made of non-magnetic material, a control unit located in a housing on top of the frame and including at least, one coil, a pusher, a magnet and a connector. Moreover, the coil and the magnet are arranged in relation to each other in such a way that when the electric pulse is applied, the magnetic flux created by the coil moves the magnet and the gate to the side of the saddle, the gate is pressed against the saddle of the outlet branch pipe, blocking the flow of the operating medium. In this case, the locking ring, the coil, the pusher and the magnet are located coaxially with the frame on its outer surface and are separated from the controllable operating medium, the housing with the control unit are designed to rotate freely around the longitudinal axis of the valve. In turn, the pusher is made in the form of a cylinder with a prominent ring for manual control.

EFFECT: invention makes it possible to create a reliable and safe to use electromagnetic gas valve of simple design with the ability to control the valve mechanically without providing a control current.
