Description
Technical field
Gas sample measuring instrument field is the utility model is related to, more particularly to a kind of Rapid replacement gas sample collector.
Background technology
The production and use of various gases will consider the influence of wherein moisture.Water is sometimes also known as a kind of " omnipotent
Solvent ", this be due to it unique physics and chemical property determined.It is directed in the research and application of every field
The analysis of moisture, microelectronics industry, oil, chemical field are especially prominent.Since nearly half a century, moisture measurement is outstanding in gas
Substantial amounts of research work has been done in terms of its micro-moisture measurement, has constantly worked out new analysis method and corresponding analyzer
Device.The capacitance method of quick response, moisture measurement applies most analyzers in gas analysis, but traditional sample gas is analyzed at present
During operating personnel simply by personal experience carry out analysis reading dew point numerical value；The pipeline being connected due to sample point with instrument
There is no the method for reasonable science, and pressure, flow, temperature can not reach a unification, specification, exact operations standard；Analyze people
The operation of member in operation is a kind of measurement process with personal experience entirely and measuring speed will typically measure one slowly
The accurate experienced analysis personnel of dew point value then need 10 minutes can read corresponding numerical value soon, then need slowly 20 minutes with
On can stablize reading.In addition, sample atmospheric pressure difference can make moisture measurement error result occur, when the dew point of gas is a certain value
When, the water content of gas is lower than the volumetric(al) moisture content of pressure gas when low when pressure is high, i.e., the water of same volume is being pressed in gas
Dew point is high when the dew point of gas is lower than pressure when power is high, and not directly proportional, the capacitance and water of condenser type water analyzer sensor
Content it is directly proportional, sensor works at one atm, therefore, containing for same volume is resulted in when the pressure of gas is high
The dew point value of water gas is higher than the dew-point temperature under low pressure, measures and also differs many when result is scaled PPM values.This just makes
Analyze pipelined sample gas moisture measurement when, because line pressure change and higher than using pressure when caused by untrue result.
At present, voltage stabilizing, current stabilization and bypass is not had to give purging quickly to put in known offline dew point and minor amount of water measurement process
Change step；So although operating personnel are not often reached using high-end analyzer, high-end analyzer is actual to accurately measure, and deposits
Instrument is caused to damage due to air inlet superpressure；There was only indivedual high-end portable dew point hygrometers such as at present：The DSP-FCI of Alpha companies
Only flow controls.Pressure and bypass Rapid replacement processing are not done.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of Rapid replacement gas sample collector, by voltage stabilizing, current stabilization, Quick side
Road purging is integrated in a cell cube, improves routine sampling speed, safely and effectively avoids caused by air inlet superpressure is to instrument
Damage, and strong antijamming capability ensures necessary accuracy in detection.
To realize object above, using following technical scheme：Rapid replacement gas sample collector, including air inlet threaded sleeve connect
Head, emptying threaded sleeve joint, measurement end connector, pressure-reducing valve, pressure gauge, needle-valve, three-way switch valve and spinner flowmeter, decompression
Valve one end connects air inlet threaded sleeve joint by connecting tube, and the other end of pressure-reducing valve connects needle-valve by connecting tube, and needle-valve leads to
Cross connecting tube to be connected with three-way switch valve, three-way switch valve connects spinner flowmeter by connecting tube, and spinner flowmeter passes through company
Adapter is connected to emptying threaded sleeve joint, and three-way switch valve also connects measurement end connector by connecting tube.Described pressure-reducing valve
It is further connected with pressure gauge.
The utility model beneficial effect：Change field assay personnel from by personal experience's analysis method to science
Change, standardization has the advanced analysis methodology that yardstick can be looked into；It is effective to shorten the testing time, improve measurement accuracy；Simple in construction,
Dexterity, service life length, is adapted to live temporary sample.
