Good guide effect can be played in first piston, second piston motion.
The further setting of the present invention：Described gag lever post includes the body of rod, and described body of rod one end is provided with locating dowel,
The central shaft of locating dowel and body of rod central shaft are misaligned, and described locating dowel extends to middle position intracavitary, and locating dowel extends to middle position
One end of intracavitary is located between first piston, second piston.
Further set using above-mentioned, due to reasons such as processing, precision so that when initial, valve element can not be in middle position
Position, the gag lever post of setting can change locating dowel in the position of middle position intracavitary, so as to change driving lever, valve by rotating the body of rod
The bit positions of core, and then ensure that valve element can be in bit positions.
The present invention's is further set again：Described the first return unit, the second return unit are back-moving spring, and first answers
The two ends bottom respectively with First pressure chamber of position part, first piston are contradicted, the two ends of the second return unit respectively with second pressure
The bottom of chamber, second piston are contradicted.
Further set again using above-mentioned, the first return unit of this structure, the second return unit set-up mode, structure letter
It is single, it is processing, easy for installation.
Brief description of the drawings
Fig. 1 is the structural representation of the drive device of driving lever；
Fig. 2 is the structural representation in the specific embodiment of the invention.
