Abstract
The utility model discloses a shifting-fork-type pneumatic piston actuator comprising a box body, a cylinder component and a shifting fork assembly, wherein the cylinder component comprises a left cylinder body, a left piston and a piston rod, the left cylinder body is fixed on the left side of the box body, the left piston is movably arranged in the left cylinder body and connected with the left rod end of the piston rod, the shifting fork assembly comprises a shifting fork and a shifting fork shaft, and the shifting fork is rotationally arranged on the box body and pushed by the piston rod. The shifting-fork-type pneumatic piston actuator is characterized in that a spring cylinder assembly is arranged on the right side of the box body and comprises a right cylinder body, a right piston and a compression spring, the right cylinder body is fixed on the right side of the box body, the right piston is movably arranged in the right cylinder body and connected with the right rod end of the piston rod, and the compression spring presses the right piston from the right side of the right piston. The shifting-fork-type pneumatic piston actuator can achieve air-stopping closing, is sensitive and reliable in action, and can also achieve manual and hydraulic driving operations.
Description
Technical field
The utility model relates to a kind of pneumatic actuator, is specifically related to a kind of fork type pneumatic piston final controlling element.
Background technique
Pneumatic actuator occupies extremely important status in industrial automation is produced, the effect of the good and bad directly decision valve of the execution of pneumatic actuator in pipeline.The driving mechanism of pneumatic actuator comprises two kinds of pinion and-rack and fork types, and the fork type pneumatic actuator is to drive shift fork by piston and piston accessory moving linearly to rotate, and rotates thereby drive declutch shift shaft.There is following shortcoming in present fork type pneumatic actuator: 1. can not realize dying closing, 2. the action sensitivity of shift fork is relatively poor, can not realize 3. manually or the operation of surging that narrow limitation is stronger.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of can realize dying closing, and it is reliable to be active in one's movements, and can realize manual, as to surge operation fork type pneumatic piston final controlling element.
The utility model is implemented by the following technical programs:
Fork type pneumatic piston final controlling element, comprise casing, cylinder assembly and pull-fork assembly, cylinder assembly comprises left cylinder, left piston and piston rod, left cylinder is fixed on the left side of casing, left piston movable setting in left cylinder is connected with the left rod end of piston rod, pull-fork assembly comprises shift fork and declutch shift shaft, shift fork is promoted by piston rod rotatable setting of casing, it is characterized in that: the right side of casing is provided with the spring cylinder assembly, the spring cylinder assembly comprises right cylinder body, right piston and compression spring, right cylinder body is fixed on the right side of casing, and right piston movable setting in right cylinder body is connected with the right rod end of piston rod, and the compression spring is from the right piston of the right side roof pressure of right piston.
After adopting technique scheme, the compression spring provides a power of closing final controlling element all the time, so in case die, the compression spring can promote piston rod and shift fork return rapidly, thereby realize the closing function of dying of final controlling element, owing to compress the setting of spring, the action meeting of piston rod is sensitive reliable simultaneously.
As preferably, be fixed with nut on the right end cap of right cylinder body, one on the bar of hand behaviour that spins with nut exposes to right cylinder body, and the other end is connected with base in right cylinder body, and base is fixed on the right piston.Above-mentioned design make the utility model can realize final controlling element manually, the operation of surging, namely under the situation of dying, can be with manual or surge final controlling element is operated; When hand behaviour bar connection handle, the utility model just can be realized the manually-operable of final controlling element so, and when hand behaviour bar connection hydraulic power, the utility model just can be realized the operation of surging of final controlling element so.
As preferably, the piston ring of right outside piston setting is the O RunddichtringO.Can prevent from like this occurring monolateral friction between right piston and the right cylinder body, improve sealing effect.
