Description

Steel bottle gas purity monitoring device Technical Field The utility model relates to the technical field of steel cylinder gas safety detection, in particular to a steel cylinder gas purity monitoring device. Background The hydrogen and oxygen/air mix and form explosive gas (explosion limit 4% -75% volume fraction), if the purity is not enough (mix air when filling for example), meet open fire after leaking and will cause disastrous result, consequently need to carry out purity detection to the hydrogen steel bottle regularly, hydrogen detects has special detecting instrument, need link to each other the gas cylinder with detecting instrument sample port through the pipeline, in this process, can't ensure whether there is hydrogen leakage in the testing process, lack the detection contrast, because the gas cylinder pressure is great, detecting instrument's detection sample port probably receives deformation damage back, once leak just is a large amount of gas leakage simultaneously, the detection security remains to promote, consequently, we propose a steel bottle gas purity monitoring device.
