Description
Technical field
The utility model relate to a kind of use on valve and can to the pneumatic actuator of the straight journey that valve opens or closes.
Background technique
At present, the operation opened or closed valve is following two kinds of situations substantially: 1, manually-operable, this Method compare trouble, and particularly large-scale valve operation is required great effort very much, time-consuming; 2, driven by motor operation, this Method compare is convenient, but motor cost is very high, and easily breaks down, and haves much room for improvement.
Summary of the invention
The utility model for the deficiencies in the prior art, provide a kind of structure simple, bear that bleed pressure is high, thrust is large, travel speed is fast, robust aluminum alloy straight journey piston type pneumatic final controlling element.
For realizing the utility model object, provide following technological scheme: aluminum alloy straight journey piston type pneumatic final controlling element, it is characterized in that comprising straight-tube shape cylinder body, the support be connected with cylinder body seal, the top cover be connected with cylinder body end sealing, be provided with along the reciprocating piston of cylinder body in cylinder body, piston two side and inboard wall of cylinder block are slidably matched, piston centre is connected with piston rod, piston-rod end passes cylinder body lower end and stretches in support, described piston centre is provided with guide sleeve, guide sleeve is placed on piston rod, guide sleeve is crimped on piston upper surface by the piston rod top nut that spins, piston upper surface center is provided with a circle projection, projection periphery is provided with a circle draw-in groove, big spring is arranged with in draw-in groove, projection is arranged with little spring, form double-spring structure, size spring top is provided with spacing collision block, large little spring is pressed on spacing collision block and piston space, spacing collision block top is connected with Limit screw, top cover is stretched out in Limit screw upper end, and it is fixing to be connected with nut adjustment.
As preferably, cylinder body, support, top cover are anodic oxidation pack alloy out.
As preferably, the surface of contact of Limit screw and top cover is provided with sealing gasket.
As preferably, the contact jaw of piston and inboard wall of cylinder block is provided with O RunddichtringO.
As preferably, the surface of contact of piston, support and piston rod is provided with O RunddichtringO and sealing gasket.
