At this, to 2 petal airbrakes 107,107 ' and the relation of fixing pin 108 be described, 2 petal airbrakes 107,107 ', owing to combining in the opposite manner and being assembled on the fixing pin 108 in Y-Y line direction of Fig. 3, therefore, be arranged to the state apart from axle center bias as follows: in the upside of Fig. 3, engage the valley of a petal airbrakes 107 ' relative to fixing pin 108, the peak portion of another petal airbrakes 107 does not engage; In the downside of Fig. 3, the peak portion of a petal airbrakes 107 ' does not engage, and the valley of another petal airbrakes 107 is fastened on fixing pin 108.2 petal airbrakes 107,107 ', petal number and peak portion have 25 in the mode of odd number.In this case, if make petal airbrakes 107,107 ' rotate, then illustrated upper and lower opposite side is the same terms, therefore, it is possible to rotate swimmingly, eccentric shaft 105 can not apply inadequate power, and the valve rod that can be fitted together to axle 104 by valve rod and be attached at the valve that this valve rod is fitted together on axle 104 has no to transmit high output torque limpingly.
Being rotated in deceleration of realizing of such vortex type retarder is described from the rotation of handle 34, the rotation of handle 34 is via handle shaft 4, parallel pin 8 and grant rotation torque to gear on worm 5, the worm gear 3 be engaged on the gear on worm 5 of running shaft can be rotated in deceleration, and can rotate up while increase output torque in the side corresponding to the rotation of handle 34.The rotation of worm gear 3, through by parallel pin 9, bolt 23 and the input shaft 106 that is arranged on worm gear 3 be attached at the eccentric shaft 105 on this input shaft 106 by parallel pin 137 and bolt 130, and through petal airbrakes 107,107 ' and the rotating dog 110 that is fastened in their card complex hole 141,141 ', be fitted together to axle 104 to the valve rod as output shaft and transmit.Be fitted together on axle 104 at such valve rod, chimeric have the valve rod being secured the valve of sense of rotation by key (not shown), output torque can be passed to the valve rod of valve, carry out the opening and closing of valve.
On the other hand, valve rod is fitted together to axle 104, in the left side of Fig. 1, opening and closing shaft flange connector 115 is fixed with by bolt 130, and then by bolt 132, opening and closing shaft 114 is installed, this opening and closing shaft 114 is provided with upper cover 19 by bolt 26, therefore, upper cover 19 axle 104 chimeric with valve rod together rotates, and can be known the aperture of valve by the display unit shown in this.In addition, shown in dotted line in Fig. 1, open or close position in order to what determine valve, the opened and closed positions installation surface A that valve rod is fitted together to axle 104 can be set, and adjusted by the opening and closing adjustment bolt 113 that arrange in the mode can come in and gone out relative to main body 101.This opening and closing adjustment bolt 113 can be fixed relative to main body 102 by adjustment bolt cap nut 112, and can carry out the sealing with outside by O type ring 136.
As mentioned above, valve operating system of the present invention, giving rotation at input side prevent function by arranging gear on worm mechanism, taking out high efficiency output torque at outlet side by arranging vortex type retarder, can obtain constructing compact valve operating system.Especially, vortex type retarder can keep the size of main body constant, by changing the change that the peak portion suitable with the petal number of petal airbrakes, the number of valley and the radical of fixing pin carry out exporting, easily the design alteration corresponding with purposes can be carried out.
As mentioned above, valve operating system of the present invention is obviously not limited to above-mentioned mode of execution, can implement in the technical scope of claims.
