Abstract
The utility model discloses a return adjustable pneumatic butterfly valve actuator, comprising a cylinder, a gear rack transmission mechanism and a solenoid directional valve capable of controlling the air inlet part of the cylinder. The gear rack transmission mechanism comprises a gear, a rack and a bracket for arranging the gear and the bracket; one end of the rack is fixed with the piston of the cylinder; and the gear of the gear rack transmission mechanism is provided with a transmission moment output device. The positions of two limiting devices are adjusted for adjusting the stroke of the rack, so as to adjust the range of the rotation angle, adjust the opening-closing angle of the controlled butterfly valve, and particularly adjust the closing angle (return stroke of the cylinder) of the butterfly valve. Simultaneously, a remote control with signal feedback and an automatic control are realized. The utility model adopts the pneumatic control, and has the advantages of simple structure, low cost for use and maintenance, non-environment pollution, long service life and wide application range.

Technical field
The utility model relates to a kind of driver of controlling the butterfly valve folding, particularly a kind of return adjustable pneumatic butterfly valve driver.
Background technique
Exist at present the butterfly valve standard-sized sheet to complete shut-down normally less than 90 °, butterfly valve and butterfly bar itself do not have self-lock ability, for the location of butterfly plate, install worm speed reducer additional on valve rod.Adopt worm speed reducer, can make butterfly plate have self-lock ability, butterfly plate is stopped on the arbitrary position.Its driving force is generally electronic, such structure more complicated.And the unlatching of valve and operating position relative fixed cannot be regulated.For the control of butterfly valve, after adjusting the folding time cycle, be not easy to change, be difficult to realize automation control and telecontrol.Like this, butterfly valve is subjected to great limitation when use and maintenance process.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of return adjustable pneumatic butterfly valve driver is provided, and the feasible unlatching and the operating position of the butterfly valve of its control of being subjected to can be regulated.
In order to solve the problems of the technologies described above, the utility model comprises cylinder, the solenoid directional control valve of the air inlet side of rack and pinion drive mechanism and may command cylinder, rack and pinion drive mechanism comprises gear, tooth bar and the support that is used to be provided with gear and tooth bar, one end of tooth bar and the piston of cylinder fix, the gear of rack and pinion drive mechanism is provided with the driving torque output unit, described support be provided with can be spacing to tooth bar one end limit stoper I, the cylinder body of described cylinder is provided with the limit stoper II spacing to the tooth bar the other end, being arranged on the support of limit stoper I position-adjustable, being arranged on the cylinder body of limit stoper II position-adjustable.
In order to make two limit stoper simple in structure, easy to adjust, described limit stoper I is arranged on and stretches out the adjustment screw on the support, described limit stoper II is arranged on and returns the adjustment piece on the bonnet of cylinder body, returns to adjust piece and be threaded with the bonnet of cylinder body.
Loosening in order to prevent to return the adjustment piece, described bonnet is provided with to be pressed on to return adjusts the piece upper locking nut.
For the telecontrol and the automation control that can realize signal feed back, described support is provided with signaling switch, but the central shaft of described gear is provided with the SC sigmal control piece of trigger signal switch when gear forwards a certain angle to.
The beneficial effects of the utility model are: the stroke of regulating tooth bar by the position of regulating two limit stoper, thereby the rotational angle range of adjusting gear, realize the adjustment of the folding angle of controlled butterfly valve, particularly the adjustment of the closed angle of butterfly valve (being the cylinder backhaul).Can also realize the telecontrol and the automation control of signal feed back.And the utility model adopts pneumatic control, and is simple in structure, uses, maintenance cost is cheap, free from environmental pollution and long service life, wide accommodation.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 looks sectional view for the left side of Fig. 1;
Among the figure: 1, stretch out the adjustment screw, 2, gear, 3, signaling switch, 4, the SC sigmal control piece, 5, internal spline, 6, cylinder, 7, solenoid directional control valve, 8, tooth bar, 9, piston, 10, return the adjustment piece, 11, cylinder body, 12, locking nut, 13, support.
Embodiment
A kind of specific embodiment as depicted in figs. 1 and 2, it comprises the solenoid directional control valve 7 of the air inlet side of cylinder 6, rack and pinion drive mechanism and may command cylinder 6.
Rack and pinion drive mechanism comprises gear 2, tooth bar 8 and support 13, and the central shaft of gear 2 is rotating to be arranged on the support 13, and tooth bar 8 is meshed with gear 2, and tooth bar 8 can be arranged on the support 13 along tooth bar is axially movable.Be provided with internal spline 5 in the gear 2.
Support 13 fixes with cylinder body 11, one end of tooth bar 8 is inserted in the cylinder body 11 and with piston 9 and fixes, have a ladder tapped hole on the bonnet of cylinder body 11, an end internal thread of adjacent piston 9 is connected with to return and adjusts piece 10 in the ladder tapped hole, the other end internal thread of ladder tapped hole is connected with locking nut 12, and locking nut 12 is pressed on to return and adjusts on the piece 10.Support 13 is provided with to stretch out adjusts screw 1, and tooth bar 8 is adjusted screw 1 and returned and adjust motion between the piece 10 stretching out under the driving of cylinder 6, stretches out to adjust screw 1 and return and adjusts piece 10 and play effect to tooth bar 8 sports limitings.
Using method: internal spline 5 is connected with the valve rod of controlled butterfly valve, by the valve rod carry-over moment of internal spline 5 to butterfly valve.
Working principle: cylinder 6 drives tooth bar 8 and does reciprocating linear motion, thereby driven gear 2 is made circular movement, and by internal spline 5 output driving torques, the switch motion of control butterfly valve realizes output then.
The time cycle of butterfly switch, a switch of butterfly valve was finished in each commutation of solenoid directional control valve 7 by solenoid directional control valve 7 controls.The demonstration of butterfly valve folding condition gives signaling switch 3 with switching signal by the action of SC sigmal control piece 4, realizes remote monitoring.
The initial position of butterfly valve and use angle can be by stretching out adjustment screw 1 and returning adjustment piece 10 and finely tune.Realize desired butterfly switch angle in the commercial Application accurately.
