天然气是极其易燃的可燃气体。如果燃气表在生产中由于某种原因,表体中密闭件封闭不严,并且在出厂检验时未检出,随后安装于住户家中产生泄漏,后果不堪设想。因此,作为对燃气表执行强制检定的部门,我们除了要按照燃气表检定规程做好燃气表示值误差等项目的检定,更要做好燃气表气密性的检定。相对于燃气表的准确性而言,燃气表的安全性更为重要。
Natural gas is an extremely flammable combustible gas. If the gas meter in the production for some reason, the body of the tight seal closed, and not detected at the factory inspection, then installed in the home leakage, the consequences would be disastrous. Therefore, as a department that performs compulsory gas meter calibration, in addition to verifying the gas meter error and other items in accordance with the gas meter verification procedures, we also need to check the gas tightness of the gas meter. Gas meter safety is more important than gas meter accuracy.
