Description
Technical field
The present invention relates to a kind of qualitative detection devices of portable gas extinguishing chemical.
Background technique
Gas extinguishing agent has cleanliness without any pollution, spurts the characteristics such as rear noresidue, is widely used in electronics computer room, science
The important places such as laboratory, book and file shop, ships power cabin and oil product workshop.Since gas extinguishing agent is mostly using standby pressure
Formula or pressure storage type storage, are pressed《Gas cylinder safely technology Supervision Code》Regulation, gas cylinder need customary detection every some cycles.When detection
Gas extinguishing agent in bottle, which is first discharged, can be reinstalled gas cylinder for the gas extinguishing agent of original qualification after detection is qualified.Mesh
Before, it generallys use gas chromatograph or spectrometer carries out analysis detection, but gas chromatograph or spectrometer are as precision instrument, valence
Lattice are higher, complicated for operation, mostly use in laboratory.Therefore firefighting bottle to be detected can only be transported back to detection unit after, by bottle
It is sampled, with medium in gas chromatograph or spectrometer analysis detection bottle.This detection method, detection time is longer, and
It is not to be detected face to face at user, is also easy to produce objection.
Summary of the invention
Its purpose of the invention, which is that, provides a kind of qualitative detection device of portable gas extinguishing chemical, solves existing inspection
Surveying device, that there are detection times is longer, and the problem of not readily portable detection, has that testing cost is cheap, structure is simple, surveys
Measure accurate feature.
It adopts the technical scheme that achieve the above object, a kind of qualitative detection device of portable gas extinguishing chemical,
Including shell, assay balance is equipped in the shell, assay balance upper end is equipped with steel cylinder, is equipped with silica gel heating on the outside of the steel cylinder
Plate, steel cylinder upper end are fixedly connected with air inlet, and the position that air inlet is located at shell exterior upper end is equipped with precise digital display pressure gauge, institute
The side for stating steel cylinder is connected with pressure hose, and pressure hose is fixedly connected with the side wall of shell through stainless steel needle valve.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that the device testing cost is cheap, pressure measurement uses precision pressure gauge, and structure is simple, matter
Measurement uses assay balance, and measurement is accurate, and steel cylinder heating uses silica gel heating plate, and heat up fast and stable；Complete equipment and solid
Sheathing material is determined with being flexible coupling, and measurement is reliable and stable, and detected value is accurately portable, and laboratory or scene can carry out qualitative inspection
It surveys, it is easy to use, it is convenient to be connect with standard sample bottle, sampling bottle using quick coupling.
Detailed description of the invention
Below in conjunction with attached drawing, the invention will be further described.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present apparatus includes shell 2, as shown in Figure 1, being equipped with assay balance 5 in the shell 2,5 upper end of assay balance is equipped with
Steel cylinder 3 is equipped with silica gel heating plate 4 on the outside of the steel cylinder 3, and 3 upper end of steel cylinder is fixedly connected with air inlet 8, and air inlet 8 is located at shell
The position of outer upper ends is equipped with precise digital display pressure gauge 1, and the side of the steel cylinder 3 is connected with pressure hose 7, pressure hose 7 with
The side wall of shell 2 is fixedly connected through stainless steel needle valve 6.
The stainless steel needle valve 6 is fixed on shell 2, is connect with the body of steel cylinder 3 using pressure hose 7, it is ensured that claim
Weight is accurate；6 valve union of stainless steel needle-like convenient for quickly with standard sample bottle, sampling bottle these detection bottles connect.
Scaling method of the invention includes the following steps：
The first step, vacuum pump are connect with needle valve, open needle valve, empty residual gas in bottle, close needle valve, remove vacuum
Pump reads assay balance registration, records steel cylinder net weight m1；
Second step prepares calibrating gas extinguishing chemical sample, and calibrating gas fire-extinguishing bottle is connect with needle valve, opens needle valve,
The slowly calibrating gas extinguishing chemical of input certain mass reads assay balance registration, record extinguishing chemical and steel cylinder gross weight m2, then mark
The quality m of quasi- gas extinguishing agent,
m=m2-m1；
Third step opens silica gel heating plate, steel cylinder is warming up to certain temperature t, and remain constant, records pressure gauge registration at this time
P；
4th step vacuumizes the gas emptied in steel cylinder, keeps steel cylinder temperature t constant, changes the quality of input gas extinguishing agent
M draws the m-P table of the gas extinguishing agent；
5th step changes input calibrating gas extinguishing chemical type, repeats above four steps, draws the m- of variety classes gas extinguishing agent
P table, to make reference.
The present invention carry out qualitative detection judgement the step of be：
The first step, vacuum pump are connect with needle valve, open needle valve, empty residual gas in bottle, close needle valve, remove vacuum
Pump reads assay balance registration, records steel cylinder net weight m1；
Second step, needle valve are connect with steel cylinder to be detected, open needle valve, slowly input the under test gas fire extinguishing of certain mass
Assay balance registration, record extinguishing chemical and steel cylinder gross weight m are read in agent2, then the quality m of under test gas extinguishing chemical,
m=m2-m1；
Third step opens silica gel heating plate, steel cylinder is warming up to certain temperature t, and remain constant, records pressure gauge registration at this time
P；
4th step, it is corresponding with calibrating gas reference table to search, that is, it can determine that gas properties.
Under certain volume, the air pressure of the different types of gas extinguishing agent of homogenous quantities at the same temperature is different.Benefit of the invention
It is different with m-P relationship of the various extinguishing chemicals under same volume and identical temperature, pass through the m-P with calibrating gas extinguishing chemical sample
Relationship Comparison determines the type of gas extinguishing agent in firefighting bottle, quick and precisely, simple and convenient, does not need to will test sample and send
It is detected in laboratory, detection process detects in front of the user, improves the confidence level of testing result.
