Abstract
The invention discloses a quick qualitative detection method for a heptafluoropropane fire extinguishing agent and an implementation device of the method, and relates to the field of gaseous fire extinguishing agents. The method mainly comprises the steps that the medium pressure in a heptafluoropropane standard sample bottle and the medium pressure in a sampling bottle at the same temperature are measured according to the principle that at the same temperature, heptafluoropropane and other fire extinguishing agents have the different saturated vapor pressures; if the medium pressure in the standard sample bottle and the medium pressure in the sampling bottle are same, a sample to be detected is heptafluoropropane; if the medium pressure in the standard sample bottle and the medium pressure in the sampling bottle are different, the sample to be detected is not heptafluoropropane. Therefore, the function of quickly and conveniently detecting the heptafluoropropane fire extinguishing agent is achieved.
Description
Technical field
The present invention relates to the Quick qualitative detection method of a kind of heptafluoro-propane extinguishing chemical and implement device, relating generally to gas
Extinguishing chemical field.
Background technology
Heptafluoro-propane extinguishing chemical is widely used in telecommunications room, radio and television equipment, Generators, subway and light rail, electricity
Gas equipment room, transformator, oil-break, book and file shop, scientific research and testing building, valuable instrument and equipment, large ship, oil product Factory Building
In place.
Owing to heptafluoro-propane extinguishing chemical is with pressure being stored in gas cylinder, specify by " gas cylinder safely technology Supervision Code ", gas
Bottle the detection cycle be 3 years once.First to discharge heptafluoro-propane in bottle during detection, detect qualified after, can be by original qualified seven
Fluoro-propane is reinstalled gas cylinder.Heptafluoro-propane unit price is higher, presently, there are the part heptafluoro-propane built-in extinguishing chemical of extinguishing chemical bottle also
Non-heptafluoro-propane problem, has a strong impact on extinguishing effect.Just should detect every when therefore dismantling heptafluoro-propane gas cylinder at user simultaneously
Extinguishing me whether heptafluoro-propane in individual firefighting bottle bottle.
At present, gas chromatograph or spectrogrph is generally used to be analyzed detecting, but gas chromatograph or spectrogrph conduct
Precision instrument, price is higher, operation complexity, mostly uses at laboratory.Therefore firefighting bottle to be detected can only be transported back detection
After unit, it is sampled by bottle, with medium in gas chromatograph or spectrometer analysis detection bottle.This detection method, during detection
Between longer, and be not to detect face to face at user, be easily generated objection.
Summary of the invention
For above the deficiencies in the prior art, the present invention proposes the fast qualitative detection of a kind of new heptafluoro-propane extinguishing chemical
Method and enforcement device.
For reaching above-mentioned purpose, the technical scheme is that
The Quick qualitative detection method of heptafluoro-propane extinguishing chemical:
The first step, prepares heptafluoro-propane standard sample bottle, fills pure heptafluoro-propane, as standard sample bottle in bottle；
Second step, is filled with testing sample in sampling bottle；
3rd step, puts in water-bath bucket by standard sample bottle and sampling bottle, measurement standard sample bottle and sampling bottle temperature, treats standard
Sample bottle is consistent with sampling bottle temperature；
4th step, respectively bioassay standard sample bottle and pressure medium in sampling bottle；
5th step, it is determined that: standard sample bottle is identical with pressure medium in sampling bottle, and testing sample is heptafluoro-propane, and pressure is different,
Testing sample is non-heptafluoro-propane.
The know-why of the present invention and having the beneficial effect that: heptafluoro-propane and other extinguishing chemical at the same temperature full
Different with vapour pressure.The present invention utilizes various extinguishing chemical saturated vapor pressure at the same temperature different, by with heptafluoro-propane mark
The saturated vapor pressure of quasi-sample compares, and determines in firefighting bottle extinguishing chemical whether heptafluoro-propane, quick and precisely, simple and convenient, no
Detecting in needing detection sample is delivered to laboratory, detection process detects in front of the user, improves the degree of belief of testing result.
The device of the Quick qualitative detection method of heptafluoro-propane extinguishing chemical, including device for detecting temperature, pressure measxurement external member
With standard sample bottle, pressure measxurement external member includes precision pressure gauge, and the entrance point of precision pressure gauge is provided with snap joint, in precision
It is provided with inlet valve between Pressure gauge and snap joint, precision pressure gauge is also associated with drain valve.
The know-why of the present invention and having the beneficial effect that: testing cost is cheap, and pressure measxurement external member structure is simple；Adopt
With precision pressure gauge, detected value is accurate；Portable, pressure measxurement external member can load in small-sized aluminium alloy box, laboratory or scene
All can carry out qualitative detection, easy to use, use snap joint, be conveniently connected with standard sample bottle, sampling bottle.
