Abstract
An actuator of a regulator is connected to one end of a valve rod. The actuator includes a shell, a limiting component, a diaphragm assembly, and an elastic element. The diaphragm assembly is movably sleeved on the valve rod. Further, the elastic element is coupled to the diaphragm assembly and is movably sleeved between the diaphragm assembly and a tip of one end of the valve rod, in a compressed state. An inner diameter of a portion of the limiting component is smaller than an outer diameter of an upper portion of the diaphragm assembly. The limiting component is located above the diaphragm assembly.
