Abstract
The invention discloses a pneumatic new hand wheel lining plastic cylinder piston actuating mechanism, which pertains to the invention and creation in the aspects of the pneumatic piston actuating mechanism and a hand wheel mechanism and aims at that the existing two actuating mechanisms, the pneumatic film actuating mechanism and the pneumatic piston actuating mechanism, all have great adverse factors when in use. As the pneumatic film actuating mechanism is restricted by the pressure and the pushing force is counteracted by a spring, the output force of a push rod thereof is small; while although the pneumatic piston actuating mechanism is provided with the spring, the cylinder is not restricted by the pressure, and so the output force of the push rod can be promoted by increasing the pressure so as to satisfy the high static press and high differential pressure situation. Currently, as the air tightness is poor, the air consumption is great, and the pressure needs to be maintained when controlling the cylinder in the regulating process, and the manufacturing cost is high due to the plating chromium processing of the cylinder wall and the piston, the pneumatic piston actuating mechanism is only applied to two-bit switching control and not economical and applicable. In addition, the existing hand wheel mechanism arranged at the front or side of the bracket has big and cockamamie mechanism, low mechanical efficiency, inconsonant mounting position and valve positioner, and hard maintenance and operation. Aiming at the problems, the invention provides a pneumatic lining plastic cylinder with the spring, great output force and good air tightness, and the new hand wheel mechanism is arranged between the bracket and the cylinder, which can greatly improve the whole layout of the existing actuating mechanism, and firstly realize the whole innovation of the pneumatic actuating mechanism.
Description
Pneumatic hand wheel lining plastic cylinder actuator is the innovation and creation that belong to pneumatic piston actuating mechanism and handwheel aspect.Its task is at existing two kinds of actuators, and pneumatic diaphragn actuating mechanism and pneumatic piston actuating mechanism in use all exist bigger unfavorable factor.Pneumatic diaphragn actuating mechanism also has spring to offset thrust because of the restriction that is stressed, and it is little to make it the push rod ouput force, though and pneumatic piston actuating mechanism has spring, the cylinder restriction that is not stressed can be passed through boost pressure, promote the push rod ouput force, to be satisfied with high static pressure, High Pressure Difference occasion.Pneumatic piston actuating mechanism only is applicable to two switching controls at present, because its poor air-tightness, air consumption is big, wants pressurize to regulating the process control cylinder, and casing wall, piston all will be handled through chromium plating simultaneously, so manufacture cost is big, and uneconomical being suitable for.Existing in addition support face side dress handwheel, it is huge, loaded down with trivial details also to exist mechanism, and mechanical efficiency is low, and assembling position and valve positioner are not in tune, and are not easy to maintenance and operation.Therefore at the problems referred to above, the invention provides and a kind ofly can take into account above-mentioned advantage, the deficiency that can remedy again, the present invention adopts lower-cost lining moulding material, with the cylinder inner wall lining, makes piston O shape circle form good sealing.Be furnished with spring simultaneously, and in the middle of support and cylinder, be provided with new handwheel.Its assembling position is coordinated, and integral layout is reasonable, and is easy to operate, laborsaving.To sum up, the present invention is the pneumatic actuator that a kind of new handwheel has strong sealing.This actuator in use, positive and negative according to actual needs effect all can realize the air to open or the air to close effect of modulating valve.Can be widely used on various types of control valves of high, medium and low voltage.
The present invention is integral cylinder and groups of holders by screw by the last lower flange of new handwheel.In the lining that upper cylinder is provided with high-abrasive material was moulded, it and O shape circle formed sealing, and air pressure signal enters cylinder chamber by the top, acts on the piston, and the thrust of its generation moves down till balancing each other with the pressure spring reaction force push rod.This moment, air pressure signal converted the stroke of push rod to, and was output into proportionate relationship with valve positioner.Middle handwheel adopts worm gear, worm structure, telescopic tube is stretched out and withdraw, control spool unlatching or close.Lower bracket push rod and valve rod coupling mechanism adopt flange combination butt joint up and down, and be easy to adjust when valve rod is connected.
Novel structure of the present invention, multiple functional, use reliably, highly versatile is the replacement type product of at present desirable band handwheel actuator.

Annotate: by cylinder cap 16; Piston 15; Spring 14; O shape circle 13; Cylinder bottom plate 9; Sealing seat 19; Screw 10 grades are formed cylinder.
Below in conjunction with accompanying drawing embodiments of the invention are illustrated its working principle.
The present invention can do modulating valve and cut-off valve actuator.Modulating valve is furnished with positioning work piece, cut-off valve distribution magnet valve.Positioning work piece adopts single gas circuit output, and control piston 15 actions are when signal air pressure enters cylinder chamber from air pressure interface 17, act on the piston 15, along with signal pressure increases, piston 15 is with spring 14 compressions, push rod 4 is moved down, up to its thrust and till the reaction force of spring 14 compression balances each other.This moment, push rod 4 did not move, and remained on a certain position.Thereby make the just corresponding certain travel position of certain signal pressure.
Actuator is in positive interaction in above-mentioned course of action, and promptly reaction latch 24 is outwards extracted, and places automated location, and telescopic tube 5 is withdrawn into the upper end.Its position does not influence push rod 4 and moves.When actuator is in reaction, handwheel 29 is clockwise rotated, rotate synchronously together with driving worm screw 21, worm gear 20 and sleeve pipe nut 7, telescopic tube 5 is moved down, after being close to locking nut 3, reaction latch 24 is advanced inwards, be placed on manually to putting, this moment, push rod 4 was locked by reaction latch 24 with telescopic tube 5, was opened or was closed by handwheel 29 adjusting control valve cores entirely.Cause this and finish handwheel automatically to manual overall process operation.As attached illustrated in figures 1 and 2.
The present invention has that volume is little, in light weight, thrust is big, control flexibly, be the wider small-sized Pneumatic hand wheel lining plastic cylinder piston actuating mechanism of new essence of a kind of application.
