Abstract
A gas leak detection device comprises a vacuum pump, an electromagnetic valve, a vacuum meter, a tee joint, a foot treading switch and a pumping mouth, the pumping port of the vacuum pump is connected to the electromagnetic valve; the electromagnetic valve is a two-position two-way constant closing electromagnetic valve; the other port of the electromagnetic valve is connected to the tee joint; the two other ports of the tee joint are respectively connected to the vacuum meter, and the pumping mouth; the electromagnetic valve is controlled by the foot treading switch. The utility model is with simple structure, convenient to operate, with high sensitivity and efficiency, can be extensively used to detect the air tightness of lithium ion battery and other container of low capacity.
Description
The utility model relates to a kind of gas leak detection device, especially a kind of lithium ion battery and bubble-tight gas leak detection device of other small containers of being applicable to.
Because the electrolytic solution boiling point in the lithium ion battery is low, high volatility is so the housing of battery must guarantee good impermeability.At present commonly used to detect bubble-tight method be after battery container welds, but do not inject as yet before the electrolytic solution, detect with the method that vacuumizes by liquid injection hole, but that the device that detects is mostly operated is more loaded down with trivial details, and efficient is low, and detection sensitivity is not high.
The purpose of this utility model is to provide pick-up unit a kind of simple in structure, easy to operate and highly sensitive for lithium ion battery and other small containers.
Gas leak detection device of the present utility model comprises vacuum pump, solenoid valve, and vacuum meter, threeway, the foot-switch and the mouth of bleeding is characterized in that the bleeding point of vacuum pump links to each other with solenoid valve; Another port of solenoid valve connects threeway; Two other port of threeway, one connects vacuum meter, and another connects the mouth of bleeding; Solenoid valve is controlled by foot-switch.
The motor of vacuum pump also can be in parallel with solenoid valve, is controlled by foot-switch simultaneously.
The bleeding point of vacuum pump can link to each other with solenoid valve with proofed sleeve, and the port of solenoid valve can connect threeway with proofed sleeve.
Bleed and also be with O-ring seal on the mouth of mouth.
Vacuum meter is medical vacuum meter.
The detecting unit that the utility model also can have a plurality of solenoid valves, vacuum meter, threeway, foot-switch, the mouth of bleeding to constitute, vacuum pump is not controlled in foot-switch control detection unit, the detecting unit vacuum pump that is connected in parallel.
Because the utility model connecting tube is short, the volume that find time is little, adds that the electromagnetic valve switch reaction is fast, so the utlity model has simple in structurely, easy to operate, is quick on the draw and the high advantage of efficient.
The drawing explanation
Fig. 1 is a synoptic diagram of the present utility model.
The 1----vacuum pump 2----solenoid valve 3----vacuum meter 4----mouth of bleeding
5----foot-switch 6----threeway 7----lithium ion battery
Referring to Fig. 1, the utility model comprises the vacuum pump 1 of 0.5 liter of a 220V~power supply, the solenoid valve 2 that the bi-bit bi-pass of a 220V~power supply is normally closed, the bleeding point of vacuum pump 1 links to each other with solenoid valve 2 with proofed sleeve, a foot-switch 5, foot-switch 5 is controlled starting or stoping of vacuum pump 1 and solenoid valve 2 simultaneously, is electrically connected as shown in drawings.Another port of solenoid valve 2 connects a threeway 6 with proofed sleeve, two other port of threeway 6, and one connects vacuum meter 3, and another connects valve 4.Adopt medical vacuum meter 3 to do the indication of vacuum tightness.When foot-switch 5 was stepped on, vacuum pump 1 and solenoid valve 2 started simultaneously, just can vacuumize battery 7, and vacuum tightness is indicated by vacuum meter 3.When foot-switch 5 lifted, vacuum pump 1 quit work, and solenoid valve 2 is in normally off again, cut off the path of battery 7 and vacuum pump 1, at this moment, if the indication of vacuum meter 3 is constant, battery 7 good seals was described then, otherwise expression gas leakage.
The size of mouth 4 of bleeding is decided according to the size in lithium ion battery fluid injection hole, is with an O-ring seal on mouth, can seal when mouth stretches in the liquid injection hole to guarantee to bleed.All exhaust pipes can connect with proofed sleeve, and pipeline should be lacked a little for well, oversizely can increase time of bleeding and the sensitivity that reduces leak detection.If foot-switch 5 is moved to A place among Fig. 1, allow test section in its control chart 1, i.e. solenoid valve 2, very the hole table 3 and the mouth 4 of bleeding; And many test sections are together in parallel, together receive on the true hole pump 1, and allow vacuum pump 1 keep working without cessation, so just can form the multiple tracks detection system, to satisfy the needs of large-scale production.
