Description
Technical field
The utility model relates to valve actuators, and in particular to a kind of high-pressure cylinder executing agency.
Background technique
In operated pneumatic valve execution cylinder, traditional common cylinder can only use the clean gas source by purification, and pressure
Range only has 0.4-0.8MPa, is unfavorable for the valve opening and closing control of natural gas line.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure cylinder executing agencies, to solve problem of the prior art, this
Utility model can be used for untreated natural gas line, bear pressure up to 25MPa.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of high-pressure cylinder executing agency, including cylinder body, gear is provided in the middle part of cylinder body, and the center of gear passes through axis and connects
It is connected to the spool for needing control valve, the two sides of gear are engaged with rack gear, and the both ends of cylinder body are equipped with spring base, and rack gear is towards spring
One end of seat is connected with rack gear seat, and cylinder spring is provided between rack gear seat and spring base, is connected with gas on the outside of spring base
Cylinder ontology, the free end of cylinder body are connected with cylinder cap, and piston is provided in cylinder body, pull rod, pull rod are connected on piston
The other end pass through cylinder body and spring base, and with rack gear seat be connected, cylinder air inlet/outlet, and gas are provided on cylinder body
Cylinder air inlet/outlet is connected by pipeline with gas supply gas source.
Further, the other end of pull rod is connected by locking nut and rack gear seat.
Further, the first YX sealing ring and O-ring seal are equipped between pull rod and cylinder body.
Further, the 2nd YX sealing ring is equipped between piston and cylinder body.
Compared with prior art, the utility model has technical effect beneficial below:
When the utility model is used, the air-flow of gas supply gas source is entered in cylinder body by cylinder air inlet/outlet, in turn
Piston is pushed to move out, piston pulls rack movement compression cylinder spring, thus with moving gear Unscrew valve；Work as needs
When closing valve, gas supply gas source is closed, the air-flow in cylinder body is discharged from cylinder air inlet/outlet, while in the work of cylinder spring
Under, piston is inwardly moved, and rack movement is pulled, so that with moving gear rotary closing valve, the utility model changes cylinder
The both ends of cylinder body are arranged in cylinder body by structure, using the rack gear in piston driving cylinder body, and then drive gear mesh valve into
Row opens or closes, and can bear control bleed pressure range and expand as 0.4-25 megapascal, application range is more extensive, in addition this reality
With it is novel when in use, air-flow is not directly entered in cylinder body and is contacted with gear and rack gear, it is possible to be directlyed adopt unprocessed
Natural gas line in gas, it is easy to use.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to Fig. 1, a kind of high-pressure cylinder executing agency, including cylinder body 31, the middle part of cylinder body 31 are provided with gear 29, gear
29 center is by being pivotally connected to the spool for needing control valve, and the two sides of gear 29 are engaged with rack gear 30, and the both ends of cylinder body 31 are equal
Equipped with spring base 32, one end of rack gear 30 towards spring base 32 is connected with rack gear seat, and is arranged between rack gear seat and spring base 32
There is cylinder spring 39, the outside of spring base 32 is connected with cylinder body 34, and the free end of cylinder body 34 is connected with cylinder cap 35,
Be provided with piston 36 in cylinder body 34, be connected with pull rod 37 on piston 36, the other end of pull rod 37 pass through cylinder body 34 and
Spring base 32, and be connected by locking nut 38 and rack gear seat, cylinder air inlet/outlet 33, and cylinder are provided on cylinder body 34
Air inlet/outlet 33 is connected by pipeline with gas supply gas source, and the first YX sealing ring 41 and O are equipped between pull rod 37 and cylinder body 34
Type sealing ring 40 is equipped with the 2nd YX sealing ring 42 between piston 36 and cylinder body 34.
The operating process of the utility model is described in detail below:
When in use, the air-flow for supplying gas source is entered in cylinder body 34 by cylinder air inlet/outlet 33, and then is pushed and lived
Plug 36 moves out, and piston 36 pulls 30 motion compresses cylinder spring 39 of rack gear, thus with 29 Unscrew valve of moving gear；When
When needing to close valve, gas supply gas source is closed, the air-flow in cylinder body 34 is discharged from cylinder air inlet/outlet 33, while in gas
Under the action of cylinder spring 39, piston is inwardly moved, and pulls rack gear 30 to move, thus with 29 rotary closing valve of moving gear.
