Zusammenfassung:	The utility model relates to an explosion-proof type small electric valve, belonging to the explosion-proof electric equipment. The utility model is suitable for being used in dangerous circumstance having explosiveness, and the automatic control of a small caliber pipe can be realized. The utility model is composed of a flame-proof type casing, a dc motor, a reducing mechanism, a stop mechanism, control circuit, and a ball-shaped valve or a cylindrical valve. The utility model can overcome the defects of the failure of the existing explosion-proof electromagnetic valve caused by the clogging of impurities in fluid.
