Afterwards, described first adhesive tape 183 and described second adhesive tape 184 is used respectively described first plastic packaging tongue tube 181 and described second plastic packaging tongue tube 182 to be stabilized in above and below the described window 330 at place, described magnet 520 position, press close to described water tumbler 130 outer surface, concrete high and low position will adjust in practical operation.
The described automatic water trap 100 so just assembled.
Below in conjunction with Fig. 1 and Figure 11, the control principle of the automatic water trap of compressed air system of the present invention is described in detail:
In use, the described gas thread of the first magnetic valve 185 and the compressed air piping of compressed air system is utilized to link together, described automatic water trap is placed vertically downward, because described first magnetic valve 185 is often opened, described second magnetic valve 186 is normally closed, compressed air containing water, oil and impurity can be entered in described automatic water trap 100 by described first magnetic valve 185, and by the filtration of described gauze 220, waste water flows into and is trapped in described water tumbler 130.Now, described float 140 rises along with the rise of waste water level, the air supply of depositing when water level reaches highest level is minimum, the conducting because magnet 520 is close of described first plastic packaging tongue tube 181, and make described twin coil bistable relay 820 due to described first contact 821(1pin) and described second contact 822(2pin) between coil conduction and work, described 4th contact 824 of output loop, the closed described second left live wire L845 making AC220V flow into described AC220V output 844 in described 5th contact 825, and then power to described normally open solenoid valve coil 187 and described normally closed solenoid valve coil 188, described like this normally open solenoid valve 185 transfers cut out to, compressed air can not enter described automatic water trap, and described normally closed solenoid valve 186 transfers unlatching to by normally closed, waste water in described cup 130 flows out.In drainage procedure, water level decreasing in described cup 130, described magnet 520 can leave described first plastic packaging tongue tube 181, but described normally open solenoid valve 185 can be made to cut out for described twin coil bistable relay 820 and described normally closed solenoid valve 186 opening remains unchanged.Further, described float 140 declines along with water level decreasing, until when magnet 520 is close to described second plastic packaging tongue tube 182, before its closing of circuit, compressed air can not enter described automatic water trap, and the air supply therefore discharged is minimum.The conducting because described magnet 520 is close of described second plastic packaging tongue tube 182, and make described twin coil bistable relay 820 due to described second contact 822(2pin) and the 3rd contact 823(3pin) between coil conduction and work, described 4th contact 824 of output loop, described 5th contact 825 disconnects the described second left live wire L845 making AC220V can not flow into described AC220V output 844, and then also just can not power to described normally open solenoid valve coil 187 and described normally closed solenoid valve coil 188, described like this normally open solenoid valve 185 recovers often to open, compressed air enters described automatic water trap, and described normally closed solenoid valve 186 is transferred to normally closed by unlatching, waste water in described cup 130 and compressed air can not flow out, described normally open solenoid valve 185 can be made to open for described twin coil bistable relay 820 and described normally closed solenoid valve 186 closure state remains unchanged.Waste water in described cup 130 constantly accumulates, and water level improves gradually, goes round and begins again.
The electric switch signal that described first plastic packaging tongue tube 181 and described second plastic packaging tongue tube 182 send, except above-mentioned function, it also can comprise the work state information of described automatic water trap 100, so described automatic water trap 100 also has work state information sensor function, in internet+new industry situation, to be necessary the electric signal transmission of described first plastic packaging tongue tube 181 and described second plastic packaging tongue tube 182, to internet, to realize Based Intelligent Control.When temperature and humidity is close, very first time interval between the electric switch signal that described first plastic packaging tongue tube 181 and described second plastic packaging tongue tube 182 send, and second time interval between the electric switch signal that sends to described first plastic packaging tongue tube 181 of described second plastic packaging tongue tube 182, close separately, belong to normal.If very first time interval extends more, be likely just because described husky net 220 stopping state is serious, reduce filter capacity; Also be likely some leakage of described normally closed solenoid valve 186, waste water all needs the more time just can reach water level, and internet will notify that staff overhauls described automatic water trap 100, makes it recover normal.As a same reason, if second time interval extended more, it is likely just described 3rd hole 630 due to described water drain bolt 150, or described second magnetic valve 186 stopping state is serious, reduce drainability, waste water needs the more time to discharge, and is reduced to lower water level.Corresponding measure also will be taked in internet.
In sum, the automatic water trap that the invention provides compressed air system has following features:
1, described main body 110, an O type circle 111, main body nut 112, housing 120, water tumbler 130, the 2nd O type circle the 113, the 3rd O type circle 114 can adopt the parts of present physical automatic water trap, and dependable performance, reduces these part manufacturing cost.
2, the internal structure of the automatic water trap of compressed air system reaches dimension simplification, eliminates narrow passage on the one hand, is conducive to discharging waste water, avoiding blocking; Except leaving very large space to described float 140 below described husky net 220 on the other hand in described water tumbler 130, and many waste water can be stored, like this, each work period is long, the time of discharging waste water can be reduced, this also reduces compressed-air actuated loss.
3, all electronic components, all in the outside of described water tumbler 130, are conducive to avoiding compressed-air actuated leakage.
4, described automatic water trap 100 also has work state information sensor function, adapts to internet+new industry situation needs, improves the intelligent management level of air compressor system.
Be understandable that, for those of ordinary skills, can be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
