Description
Technical field
The utility model relates to a kind of final controlling element, especially a kind of pneumatic actuator structure.
Background technique
The actuator of pneumatic actuator and controlling mechanism are unified entirety, and there are diaphragm type, piston type, fork type and pinion and-rack in its actuator.Piston type stroke is long, is applicable to require the occasion compared with high thrust; And diaphragm type stroke is less, directly ovable valve stem can only be with.Shift fork type pneumatic actuator has that moment of torsion is large, space is little, torque curve more meets the features such as the torque curve of valve, but not bery attractive in appearance; Be commonly used on the valve of high pulling torque.Pinion and-rack pneumatic actuator has structure simple, and stable action is reliable, and the advantages such as safety anti-explosive, and in power station, chemical industry, oil refining etc. are widely used in the higher production process of safety requirement.
Model utility content
The purpose of this utility model is to provide a kind of pneumatic actuator structure, to solve the problem proposed in above-mentioned background technology.
The purpose of this utility model is achieved by following technical proposals: a kind of pneumatic actuator structure, comprises upper cover, film sheet, supporting plate, valve rod, valve seat, valve body, spool, push rod, balance spring and lower cover; Described valve inner is provided with valve seat and described valve seat side is provided with spool; Described spool is installed on stem internal, and described valve rod one end is connected with push rod; Described push rod top is provided with balance spring, and supporting plate side is fixed in described balance spring one end; Described valve body top is provided with lower cover, and described lower cap surface is provided with upper cover; Film sheet is provided with between described upper cover and lower cover.
Further, described upper cover is semicircular structure, and described upper cover top is provided with air outlet hole.
Further, described lower cover is semicircular structure, and described lower cover and upper cover are bolted to connection.
Further, described body wall is provided with two circular valve ports.
Further, described spool is triangular structure, and stem internal is fixed in described spool one end.
Compared with prior art, the beneficial effects of the utility model are these novel a kind of pneumatic actuator structures, this structure can control valve, working efficiency is high, simultaneously quality light and handy, be convenient to install, practical, manufacturing price is cheap, there are good social effect and economic benefit, are applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
In figure: 1, upper cover, 2, film sheet, 3, supporting plate, 4, valve rod, 5, valve seat, 6, valve body, 7, spool, 8, push rod, 9, balance spring, 10, lower cover.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technological scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of pneumatic actuator structure, comprise upper cover 1, film sheet 2, supporting plate 3, valve rod 4, valve seat 5, valve body 6, spool 7, push rod 8, balance spring 9 and lower cover 10; Described valve body 6 inside is provided with valve seat 5 and described valve seat 5 side is provided with spool 7; It is inner that described spool 7 is installed on valve rod 4, and described valve rod 4 one end is connected with push rod 8; Described push rod 8 top is provided with balance spring 9, and supporting plate 3 side is fixed in described balance spring 9 one end; Described valve body 6 top is provided with lower cover 10, and described lower cover 10 surface is provided with upper cover 1; Film sheet 2 is provided with between described upper cover 1 and lower cover 10.
As a kind of technical optimization scheme of the present utility model: described upper cover 1 is semicircular structure, and described upper cover 1 top is provided with air outlet hole; Described lower cover 10 is semicircular structure, and described lower cover 10 and upper cover 1 are bolted to connection; Described valve body 6 sidewall is provided with two circular valve ports; Described spool 7 is triangular structure, and valve rod 4 inside is fixed in described spool 7 one end.
In use, when pressurized air enters pneumatic actuator from Guan Zui, gas push double-piston is to two ends straight line motion, and the gear on the rack drives running shaft on piston counterclockwise rotates 90 degree, and namely valve is opened for the utility model.Now the gas at Pneumatic executive valve two ends chews discharge with pipe.Otherwise when pressurized air enters the two ends of pneumatic actuator from Guan Zui, the two plug of gas push is to middle straight line motion, and the gear clockwise direction on the rack drives running shaft on piston rotates 90 degree, and namely valve is closed.Gas now in the middle of pneumatic actuator chews discharge with pipe.It is more than the transmission principle of standard type.According to user's request, pneumatic actuator can become the transmission principle contrary with standard type by device, namely makes an accurate selection of axle clockwise direction and rotates as Open valve, counterclockwise rotate as throttle down.Single-action pneumatic executor pipe is chewed as suction port, and pipe is chewed as exhaust port.Air inlet chewed by pipe is Open valve, by spring force throttle down when dying.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
