Embodiment
The present invention is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of valve regulated mechanism of Long travel comprises cylinder body 4, piston 5 and push rod 7.Cylinder body 4 top is fixedly installed upper cylinder cover 6, and bottom is fixedly installed lower cylinder cap 2.The upper cylinder cover 6 of cylinder body 4 and lower cylinder cap 2 are equipped with suction port.In order to improve global stability, bottom lower cylinder cap 2, be fixedly connected with welded plate 1, between upper cylinder cover 6 and lower cylinder cap 2, stay bolt 3 is set.The upper cylinder cover 6 of cylinder body 4 is fixedly installed column 9.Column 9 upper end is fixedly installed connecting plate 10, is provided with the through hole for push rod 7 in the middle part of connecting plate 10.Connecting plate 10 is for being connected with valve.Push rod 7 is arranged connecting rod 11, connecting rod 11 the other end is socketed on column 9.One end link position feedback rod 12 that connecting rod 11 is connected with column 9, the other end connecting positioner 8 of position feedback bar 12, position feedback bar 12 is provided with position sensor.Upper cylinder cover 6 is fixedly installed filtering pressure reducer 13, filtering pressure reducer 13 pipeline connects amplifier 14, and amplifier 14 pipeline connects the suction port on upper cylinder cover 6 and lower cylinder cap 2.Positioning work piece 8 connects filtering pressure reducer 13 and amplifier 14.
During work, bleed pressure enters by positioning work piece 8 after filtering pressure reducer 13, and positioning work piece 8 is according to Signal Regulation source of the gas, and source of the gas enters cylinder body 4 after amplifier 4, promotes piston 5, thus promotes push rod 7, makes valve reach precalculated position.Push rod 7 height and position is transferred to positioning work piece 8 by position feedback bar 12 in real time.
Shown in the above and figure is only the preferred embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
