The second appendix 600 connection nitrogen gas tank 700 is crossed, the second tap 803 connects gas outlet, when having gas to suppress in moisture monitor 400
When gas, 803 pressure release of the second tap, (it can be by opening valve on gas outlet, pressure release avoids exploding, due to being in nitrogen gas tank
High pressure nitrogen, Gu when occur feeling suffocated in moisture monitor phenomenon when, open second switch valve, gas will not enter nitrogen gas tank, and
It is to be discharged from gas outlet).
It should be noted that locking buckle 900, the first appendix 300, two become a connector 800 and adopt in the utility model
With existing in the market, first switch valve 200, second switch valve 500 are existing switch valve in the market.
Usage is as follows: the drying process step of moisture monitor: drying device and moisture monitor 400, nitrogen gas tank 700 connect
After connecting, moisture monitor 400 is connect by measurement pipe with tested stainless steel barrel, first switch valve 200, second switch valve
500 are in close state, and after connecting, second switch valve 500 is opened at 1/3, then slowly open first switch valve 200, in advance
Anti- throughput is excessive, damages to moisture monitor 400, with the dry electrolysis of the small volume airflow of 20mL/min or so or less
Pond, after powering on, gauge outfit shows 1500uL/L or so, until registration is 5.0Ul/l hereinafter, more lower better.Measurement: dried
After journey is handled well, then after moisture monitor 400 being switched to tested gas sample, big bypass flow valve is first opened, then open big sampling valve
Making total flow is about 1.1L/min, then adjusts flow valve, makes measuring flow 100ML/min, and bypass flow is about 1L/min,
It is down to 5Ul/L to registration, when below and more stable, records this value as background values.It shuts down: every time after measurement, Ying Guan
Control valve is placed in " drying " by small sampling valve, and measuring flow is reduced to 20ml/min hereinafter, turning down bypass flow, by micro-moisture
Instrument 400 and nitrogen gas tank 700 connect ventilation, and continuing to be powered makes electrolytic cell and gas circuit holding and drying regime, facilitate next use.
The utility model is simple and practical in structure, the nitrogen in nitrogen gas tank 700 is delivered to again after drying device is dry micro-
Moisture Meter 400 is measured, since the nitrogen in nitrogen gas tank 700 is after removing water molecular sieve, the moisture content in nitrogen greatly reduces, energy
It is enough that moisture monitor 400 is preferably dried, in addition, by setting the first strainer 104, the second strainer 105, it can be to dry
The nitrogen of dry moisture monitor 400 carries out secondary filter, filters twice, filter effect is good, effectively reduces dry micro-moisture
Impurity in the nitrogen of instrument.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
