Description
Technical field
The utility model relates to the technical field of gas leakage hunting apparatus, relates in particular to the special leakage detection apparatus of a kind of halogen gas and aiding start structure.
Background technology
The special leakage detection apparatus of fluorine type gas (or other halogen gass) of high frequency magnetic field ionization type, this leakage detection apparatus is widely used in the product such as sf6 quantitative leak, air-conditioning leak detection; Under some environment (humidity, dust, air pressure), have the part unsuccessful phenomenon of starting shooting, cannot normally use, need repeatedly frequently start, but under many circumstances, still cannot normal boot-strap, thereby cause the overheated and burn out detector of part of devices, cause device damage.
The fluorine type gas leakage detection apparatus of high frequency magnetic field ionization type, under normal circumstances, the high-frequency electrical producing on the electrode slice of the high frequency oscillator in its detector should be able to make the low-pressure air in ionization chamber ionize and (produce mulberry aura from magnetic field, we are referred to as build-up of luminance), now ionization chamber is a load to oscillator, so a lower voltage of oscillator output is below 2v, meter reading is in 100, and at this time instrument enters normal operating conditions.
But many times, high frequency oscillator is being subject under the impacts such as ambient temperature, humidity, air pressure, efficiency decreases, the high frequency magnetic field now producing on radio-frequency coil electrode is because energy is inadequate, deficiency is so that low-pressure air ionization in ionization chamber, ionization chamber is now for oscillator, load is very little, even so output terminal has a higher output voltage, generally in 20v left and right, in ionization chamber, also do not have any purple aura, instrument cannot normally be worked, and we are referred to as to start shooting unsuccessful.
At present, on market, not there is the regular normally equipment of build-up of luminance problem of start-up of the special leakage detection apparatus of halogen gas that can solve high frequency magnetic field ionization type, for the problem of this regular normally build-up of luminance start, in industry, cannot find the actual cause of this problem and the method that essence addresses this problem of producing always.
The applicant had also once attempted following methods, probed into the actual cause that causes system successfully to start, and then solved the certain problem starting.
Method one: expand the oxygen supply amount of ionization chamber, help to start; Those skilled in the art is adjusted into semi open model by ionization chamber shell from enclosure-type, can improve the successful probability of start.
Method two, the spy-hole of ionization chamber upper cover is expanded, increase entering of light, help to start; Such change is resultful for improving start success ratio, but as accurate device and heater members, is not suitable for open exposedly, and the pollution of dust etc. can cause product failure.
Method three, increase heating element in ionization chamber the inside, reduce the humidity of ionization chamber, help to start, test effect is not obvious.
Method four, the applicant understand may be the too high ionization chamber that causes of humidity in the time vacuumizing, because moisture in air liquid state is converted into gaseous state, volume expansion, therefore vacuum tightness cannot reach, so it is unsuccessful to start shooting.The applicant advises client in use for this reason, should under air conditioner surroundings, start shooting, and after starting shooting successfully, moves to the place that needs use.But found that, such starting-up method neither 100% reliably start.
Method five, the applicant find some time, if the vacuum tightness in increase ionization chamber, some time can increase start successful possibility, for this reason, in the operation instruction of product, there is such description: " if liquid crystal display is 1, showing to start unsuccessful; please cover detector air intake opening 3-5 second with thumb; then unclamp, repeated multiple times ", but in the time that reality is used, not that process just can deterministic addressing the startup problem so each time.
The material of method six, replacing probe body, because in actual tests, remove the probe body successful probability of can reasonable raising once starting shooting, the applicant suspects it is whether that the material of shell has changed the magnetic field in ionization chamber, so used the different materials such as aluminium alloy and ABS plastic, stainless steel to compare test, as long as but the result of test is to have filled shell just to have impact, which kind of Effect of Materials shell adopts little.
Therefore, even if although those skilled in the art make multiple trial as the applicant, also actual cause and the solution that still cannot look for the start of ionization chamber internal oscillator build-up of luminance, this also just can be interpreted as the regular normally equipment of build-up of luminance problem of start-up what does not still occur the special leakage detection apparatus of halogen gas that can solve high frequency magnetic field ionization type in the market.
Therefore, the applicant is devoted to develop the special leakage detection apparatus of halogen gas of the normal build-up of luminance start that can ensure ionization chamber internal oscillator, and can assist the normal build-up of luminance start aiding start structure of ionization chamber internal oscillator.
