Description
Technical field
The utility model relates to pneumatic actuator technical field, particularly a kind of three-position type pneumatic actuator.
Background technique
Pneumatic actuator is the class in final controlling element, and it utilizes source of the gas to drive unlatching or the closedown of actuator's (being generally valve), with the flow of control media.Three-position type pneumatic actuator is a kind of actuator of special requirement, provides 0 °, 45 °, 90 ° or 0 °, 90 °, the three-position type mode of operation of 180 °.Neutral position is that the mobile mechanical braking produced of dependence two sub-pistons realizes.Neutral position is adjustable.Final controlling element as 90 ° of strokes can provide 20 °, 30 °, 50 °, the neutral position of 70 ° of grades.
The sealed cover of the side cylinder body of prior art is arranged in cylinder body, is subject to longitudinal pulling force for a long time, and the sealing gasket at two ends and O type circle serious wear, cause sealing effect to reduce, working life is short, haves much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure simple, good sealing effect, effectively prevents from revealing, the three-position type pneumatic actuator increased the service life.
For realizing the utility model object, provide following technological scheme: three-position type pneumatic actuator, it is characterized in that the side cylinder body comprising middle Master cylinder body and be tightly connected with Master cylinder body two ends, side cylinder body end arranges sealed cover, side cylinder body and Master cylinder body are separated into two cavitys sealed, Master cylinder body center is provided with driving gear, driving gear connects output shaft, driving gear upper and lower sides is provided with a tooth bar engaged with driving gear, tooth bar end is all connected with piston, piston two ends and Master cylinder body inwall are slidably matched, sub-piston is provided with in the cylinder body of side, sub-piston center is connected with side piston rod, side piston rod passes sealed cover and stretches in Master cylinder body, sealed cover center is provided with protruding stop collar, stop collar center has the wealthy hole of guiding, sealed cover upper and lower surface edge is provided with ring-shaped depression, Master cylinder body coordinates with side cylinder body end face and is connected in depression, sealing gasket is provided with in depression, sealed cover and Master cylinder body and side cylinder body is made to keep sealing.
As preferably, Master cylinder body and side cylinder body are anodised aluminum alloy.
As preferably, in Master cylinder body, wall liner is moulded.
As preferably, piston and sub-piston and Master cylinder body, the side cylinder body inwall place that is slidably matched is provided with sealing gasket and O RunddichtringO.
As preferably, the opposing side of piston and side piston rod offers 3 grooves.
The utility model beneficial effect: the utility model, by the improvement to sealed cover plate structure and mounting structure, substantially increases leakage efficiency, and mount scheme, extend the working life of whole equipment.
