Electromagnetic blow-down valve

The electromagnetic blow-down valve comprises a filter element, a gas guide pipe, an upper valve body, a lower valve body, a sealing membrane, a movable iron core, an electromagnetic coil, a water baffle, a timing controller and the like, the filter element and the gas guide pipe can enable clean gas in a gas storage cylinder to enter the electromagnetic valve, the movable iron core is sucked up after the coil is powered on, a sealing opening of the membrane is opened, and the valve body is sealed. Therefore, sewage in the air storage cylinder can be discharged through the exhaust hole, and the function of discharging small solid particles such as rust powder in the air storage cylinder is achieved. 本发明公开了一种电磁排污阀，包括滤芯、导气管、上阀体、下阀体、密封膜片、动铁芯、电磁线圈、挡水板、计时控制器等部件，滤芯和导气管可以将储气筒内干净的气体进入电磁阀内部，线圈通电后将动铁芯吸起，使得膜片的密封口打开，从而使储气筒内的污水能够通过排气孔排出，具有排放储气筒内铁锈粉末等小固体颗粒物的功能。
