Further, the material of described piston is aluminum alloy, central angle θ≤30 ° of the centerline of described piston.
The beneficial effects of the utility model are:
1, by controlling rod will be provided with on valve rod, controlling rod is connected with pneumatic equipments such as piston rods, making the control of valve rod is pneumatic control, and the air pressure of pneumatic control derives from gas holder, makes pneumatic control not need open compressor at any time or can not configure compressor;
2, by the center line of controlling rod, cylinder, piston and piston rod is set to circular arc, compared with prior art, the quantity of cylinder is less, and piston rod acts on power on controlling rod all the time perpendicular to controlling rod place radius, makes the power of piston rod be converted into the moment of torsion of valve rod to greatest extent;
3, by controlling rod and piston rod are set to hollow stem, make whole control gear lighter, more save material, cost is lower.
4, by cylinder and piston are set to aluminum alloy material, can reduce the overall weight of Pneumatic actuator, piston is lighter, makes the control of piston more flexible.
Accompanying drawing explanation
Fig. 1 is the structural representation of model utility.
Mark in figure: 1 be valve rod, 2 be cylinder, 3 be controlling rod, 4 be piston, 5 be piston rod, 6 for valve rod frame.
