Example.
Fig. 1 is the attachment structure schematic diagram of double-acting cylinder and solenoid directional control valve in the prior art, reference picture 1, double-acting cylinder
110 be the firsthand Standard Cylinder of producer, including cylinder piston rod 113, the first air admission hole 111 and the second air admission hole 112；When
Compressed air is out of the second air admission hole 112 input cylinder barrel 116, and under the promotion of compressed air, cylinder piston rod 113 is from cylinder
Stretched out in cylinder 116, and when compressed air inputs cylinder barrel 116 from the first air admission hole 111, then under the promotion of compressed air,
Cylinder piston rod 113 from moving round about, so as to realize that the opening of vacuum valve acts with shut-off.
The commutation of compressed air is controlled by solenoid directional control valve, reference picture 1, and solenoid directional control valve 120 is two five logical
Magnetic valve, including air inlet 123, the first venthole 121, the second venthole 122, air inlet 123 are connected with air pump by tracheae
(not shown), for inputting compressed air, the first venthole 121, the second venthole 122 by tracheae 130 respectively with it is double
Take offence the first air admission hole 111 of cylinder 110, the second air admission hole 112 connects, and solenoid directional control valve 120 is by controlling the first venthole
121st, the switching of the gas channel of the second venthole 122, so as to be commutated to the compressed air of double-acting cylinder 110, valve is realized
The opening of door acts with shut-off.
Due in the prior art, the air inlet 123 and air pump of solenoid directional control valve 120, the first venthole 121 and the first air inlet
