Actuator for smoke exhausting valve

The utility model relates to a smoke exhausting valve executor which is an actuator used for smoke exhausting valves of a ventilating pipeline and an air conditioning system pipeline. The utility model is composed of an electromagnet, a lever, a cam, a main shaft and a handgrip. The lever is composed of a stopping lever and a driving lever. Due to the fact that two-stage lever transmission is adopted, driving force is reduced, and the action current of the electromagnet is reduced. Two adjacent parts which compose kinematic pairs and are in the utility model are made from different metals, the possibility of rust is reduced, and the dependability of action is greatly enhanced. Building block type structural design is adopted by the utility model, the utility model is used as a basic form, and an extended function is accomplished after the utility model is combined with other actuators. The utility model has the characteristics of novel structure, refinement, beautiful appearance, convenient operation, reliable action, etc. The utility model belongs to the novel smoke exhausting valve executor which has economy and practicability.
