Background

When using the gas detector of electrochemical sensor principle, if the sensor is not installed in the gas circuit for a long time but is placed in the air environment for a long time, the sensor may be aged and disabled, and the service life of the equipment is affected. Therefore, all kinds of electrochemical principle gas detectors need to seal the gas inlet and the gas outlet after detection is finished, so that the service life of the transmitter is prevented from being influenced by attenuation of air on the electrochemical sensor. However, most of the sealing means of the current commercial products are continuous ventilation nitrogen sealing after the use is finished or plug is installed at the air inlet and outlet, but the continuous nitrogen sealing cost is high, the air inlet and outlet installation plug is relatively complex to operate and is easy to damage threads due to frequent disassembly and assembly, and on the other hand, the plug can not completely seal gas permeation, and the sensor still has wear phenomenon.
