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

[0001] The invention relates to a rapid qualitative detection method and an implementing device for a heptafluoropropane fire extinguishing agent, and mainly relates to the field of gas fire extinguishing agents. Background technique

[0002] Heptafluoropropane fire extinguishing agent is widely used in telecommunications room, radio and television equipment, generator room, subway and light rail, electrical equipment room, transformer, oil circuit breaker, library and archives, scientific research and test building, valuable equipment, large ships, oil plant and other places .

[0003] Since the heptafluoropropane fire extinguishing agent is stored in the gas cylinder under pressure, according to the "Gas Cylinder Safety Technical Supervision Regulations", the gas cylinder inspection cycle is once every 3 years. During the test, the heptafluoropropane in the bottle should be discharged first. After the test is passed, the original qualified heptafluoropropa...

Examples

Embodiment

[0021] like figure 1 Shown, embodiment of the present invention is as follows:

[0022] It includes a precision pressure gauge 1, and the precision pressure gauge connector 3 is convenient for quick connection with standard sample bottles and sampling bottles 6 .

[0023] An inlet valve 2 is provided between the quick connector 3 and the precision pressure gauge 1 , and a discharge valve 4 is also provided on the precision instrument gauge 1 .

[0024] Step 1, prepare a standard sample bottle of heptafluoropropane, and fill the bottle with pure heptafluoropropane as a standard sample bottle;

[0025] Step 2, filling the sampling bottle with the sample to be tested as a sampling bottle;

[0026] Step 3, put the standard sample bottle and the sampling bottle into the water bath barrel, use the thermometer 5 to measure the temperature of the standard sample bottle and the sampling bottle, until the temperature of the standard sample bottle is consistent with the sampling bottle...
