Contained spring and external springs, the internal diameters of the external springs be greater than the internal diameter of contained spring, and the contained spring and outer
Portion's spring upper and lower ends are arranged with plastic card head I and II top outer interior side contacts formula of plastic card head respectively, the plastic card head I
Bottom rises up into setting on the inside of contained spring, and the plastic card head I is connected through a screw thread mode with casing outer end and fixes, institute
It states sleeve outer wall and is also threaded with nut.
This setting optimizes pneumatic actuator spring structure, is equipped with contained spring and external springs this 2 springs,
Left side plastic card head I is fixed with intermediate casing using screw connection manner, and the plastic card head II on right side and casing activity are interspersed, and lead to
It crosses nut to be limited, easy to install and use, safety is good, effectively prevent spring breakage, ensures the service life of spring, and have
Effect saves the volume of valve steel body, saves production cost.
Preferably, it is hollow setting that the plastic card head I is identical with II length of plastic card head and intermediate, and the plastics
Clamp II and casing are the interspersed connection of activity.
Preferably, the nut is located on the outside of plastic card head II and is arranged, and the outer dia of the nut is greater than plastic clip
The inside diameter at first II intermediate position, described sleeve pipe outer wall are additionally provided with and the matched external screw-thread of nut inner wall.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
