The invention discloses an electromagnetic coil device comprising an energy storage shutdown valve module. The electromagnetic coil device comprises the energy storage shutdown valve module and an electromagnetic coil structure, wherein the energy storage shutdown valve module is connected with the electromagnetic coil structure through a cable; the electromagnetic coil structure is connected with a valve body; a redundancy control circuit arranged on the energy storage shutdown valve module and an electromagnetic coil form a closed loop control circuit which is connected with an alarm through a cable; the alarm supplies power to the energy storage shutdown valve module for energy storage, and transmits a valve shutdown signal to the energy storage shutdown valve module; and the redundancy control circuit of the energy storage shutdown valve module automatically releases stored electric energy to the electromagnetic coil to ensure that the electromagnetic coil generates enough directional magnetic force for unlocking a shutdown valve. The electromagnetic coil device has the advantages that the energy storage shutdown valve module is provided with a simple and reliable circuit, is low in power consumption, and has the functions of receiving a passive switching value closing signal and / or automatically unlocking the shutdown valve during a power failure; circuit elements are separated from the electromagnetic coil, so that the circuit elements cannot be damaged during the plastic package of the electromagnetic coil, and the requirement on an explosion-proof standard is wholly met; and the safety and the reliability of a shutdown valve control function are significantly improved.
Description
technical field [0001] The invention relates to an electromagnetic coil assembly containing an energy storage valve closing module, in particular to a redundant closed-loop control circuit composed of an explosion-proof energy storage valve closing module and an explosion-proof electromagnetic coil on the circuit, and the two are packaged into a whole structurally , and is suitable for the electromagnetic coil assembly of the electromagnetic gas emergency shut-off valve including the energy storage closing valve module. Background technique [0002] At present, the electromagnetic coil driving control of the civil electromagnetic gas emergency shut-off valve is provided by the household gas alarm.
