Working principle:
Because 90% of the crust breaking cylinder stroke of aluminum electrolytic tank is to do the no load movement of F.F..Can consider the pressurized air supply back cavity of cylinder ante-chamber in F.F. process to realize energy-conservation requirement, control principle as shown in Figure 3, when use, gas source is connected with the P1 mouth of two-position five-way Pneumatic valve 21, the B1 mouth of two-position five-way Pneumatic valve 21 leads to cylinder 22 back cavities, the suction port P mouth 25(that the A1 mouth of two-position five-way Pneumatic valve 21 leads to solar term pneumatic valve of the present invention by the container type bonnet of cylinder 22 communicates with P chamber 30), the working hole A mouth 24 of solar term pneumatic valve is connected to the ante-chamber (communicating with active chamber A chamber 31) of cylinder 22, and the relief opening O mouth 23 of solar term pneumatic valve is connected to the B1 mouth (communicating 29 with O chamber) of two-position five-way Pneumatic valve 21 by the hole path in the bonnet of cylinder 22.
Position as shown in Figure 3, in the time of gas source P1 confession gas, due to cylinder 22 front and back two chamber lifting surface area differences, stretch out motion so cylinder piston rod does, the working hole A mouth 24 of ante-chamber pressurized air by air throttle is with relief opening O mouth 23 back cavity (now air throttle present position as shown in Figure 1) of supply to cylinder 22 that communicate.In the time that piston rod touches workpiece, load determines pressure size, cylinder 22 ante-chambers rise to press and cause air throttle active chamber A chamber 31 pressure to raise, active chamber A chamber 31 pressure arrive the left chamber 26 of upper cover in control piston 4 left sides by the control channel 20 below valve body, when control piston 4 left side pressure overcome after spring 5 pressure on control piston 4 right sides, control piston 4 moves right and causes air throttle piston 7 to be with ovable valve stem 11 to move right, make the O chamber 29 of air throttle not connected under the effect of E shape circle 12 with active chamber A chamber 31, and A chamber 31 and 30 intercommunications of P chamber, be that working hole A mouth 24 and suction port P mouth 25 communicate, now cylinder 22 ante-chamber pressurized air just can be by the A1 mouth of two five-way Pneumatic valves 21 discharged to atmosphere, cylinder is gone to end of travel and is completed crust breaking work, when after switch valve with two-position and five-pass 21 commutations, the suction port P mouth 25 of air throttle is by the A1 confession pressurized air of two-position five-way Pneumatic valve 21, and commutate moment at two-position five-way Pneumatic valve 21, air throttle P chamber 30, active chamber A chamber 31 and O chamber 29 are all without pressure, control piston 4 reset under the effect of spring 15 power between valve rod 11 and screw plug 14 (getting back to position shown in Fig. 1), complete after commutation at two-position five-way Pneumatic valve 21, air throttle P mouth 25 is connected with source of the gas causes P chamber 30 pressure to raise, gas arrives the left chamber 28 of valve body in piston 7 left sides by air throttle P chamber 30 control channel 20 above, because the power of spring 15 is very little, so valve body inner carrier 7 is with ovable valve stem 11 to move right, thereby make the O chamber 29 of air throttle and active chamber A chamber 31 not connected under the effect of E shape circle 12, and P chamber 30 communicates with 31 chambeies, active chamber A chamber, the P mouth 25 that is air throttle communicates with A mouth 24, gas can be by this path to cylinder 22 ante-chamber air feed, the gas of cylinder 22 back cavities from the B1 mouth of switch valve with two-position and five-pass 21 discharged to atmosphere, cylinder can normally be retracted.When the P of air throttle mouth 25 is during without pressure, P chamber 30 is without pressure, and piston 7 is got back to initial position (position shown in Fig. 1) execution circulation under the effect of spring 15 power.This manner of execution can make the pressurized air complementation between two chambeies of cylinder in the unloaded movement speed of accelerating crust breaking cylinder, thereby realizes energy complement between two chambeies, reaches energy-saving effect.Can make again pneumatic control system stable working, reliability is high simultaneously.
Above are only part technological scheme example of the present invention, be not used for limiting scope of the present invention, equivalent variations and modification that all foundations claim of the present invention is done, be the scope in technical solution of the present invention.
