Power output unit, piston inner hole are designed with radial seal with cylindrical, and to ensure the air-tightness of executing agency, stroke limit part is adjustable
The stroke of whole executing agency.Spring cavity is equipped with modular spring, deep gouge is provided with piston, to fixed spring, this practicality
It is new to need to adjust number of springs according to user in real time to meet the thrust requirements of user, and without changing executing agency,
Avoid causing the economic loss of user, it is stamping parts to descend membrane cover thereon, handling ease and cost is relatively low.The executing agency is included just
Two kinds of forms of action and reaction, with handwheel and without two kinds of specifications of handwheel.With existing more spring diaphragm actuator phases
Than the higher reachable 0.7MPa of the more spring cylinder piston actuator supply gas pressures of single-acting, the life-span is longer, equivalent specifications production
Product, thrust output is bigger, and modular cluster spring design easily facilitates change executing agency thrust and meets user's request.
In this way, the utility model is that a kind of fault rate is low, long lifespan, thrust output scope are big, lower-cost single-acting
More spring cylinder piston actuators.
