ELECTROMAGNETIC VALVE Russian patent published in 2020 - IPC F16K31/02 

FIELD: valve industry.

SUBSTANCE: invention relates to valve industry, in particular to valves with electromagnetic drive with shutoff member position signaling, and can be used in remote control systems for gas supply in chemical, gas, power and other industries. Electromagnetic valve comprises housing with inlet and outlet nozzles, electromagnet consisting of magnetic conductor holding and afterburner windings, anchor connected through a rod with a spring-loaded locking element and interacting with a stack of magnetic conductor, a signaling device of the position of the shut-off element in the form of a magnetically controlled contact located in the housing of the magnetic conductor. Shutoff member position indicator is made in the form of a compensation coil with a magnetically controlled contact located inside it. Holding coil winding and signaling coil compensation winding are connected in parallel to electromagnetic valve supply voltage source so that direction of field strength from retaining winding is opposite to direction of field strength of signaling coil in area of magnetically controlled contact installation. Electromagnetic valve ensures matching between the shut-off element state and the magnetically controlled contact state in the wide range of the supply voltage and the ambient temperature of the electric valve.

EFFECT: electromagnetic valve is proposed.
