DOUBLE ELECTROMAGNETIC VALVE Russian patent published in 2019 - IPC F16K31/02 

FIELD: transportation.

SUBSTANCE: invention relates to the field of transportation of low-pressure gaseous media, namely to the area of shutoff valves, and can be used in heat power systems at thermal stations, in vacuum systems, in petrochemical and gas equipment. Double electromagnetic valve comprises a housing accommodating the first seat, the first membrane gate with unloading opening, the first membrane with bypass holes. Between the case flange and its cover the first slide valve is installed with possibility of overlapping / opening of unloading hole of the first membrane shutter, connected to anchor of the first electromagnet and to the first membrane gate. On the housing gas supply means and gas outlet means are fixed, wherein gas outlet means is made in form of pipeline rigidly fixed in housing wall by first end extending beyond housing limits. Inside the housing there is a second seat, a second membrane gate with a discharge opening, a second membrane with bypass openings and a second slide installed to shut off / open the discharge opening of the second membrane gate connected to the armature of the second electromagnet and to the second membrane gate. First gas duct is located between gas supply means and second membrane gate, wherein first shutter membrane is configured to shut off gas duct, body volume is divided by a partition into two parts, the first of which is located under the membrane of the first gate, and the second part is located under the membrane of the second gate, note here that said second gate is arranged to discharge gas into gas outlet. Note here that gas outlet means adjoins second diaphragm shutter.

EFFECT: technical result achieved during implementation of the developed device consists in simplification of shutoff valves of the gas line.
