摘要
分析了中压燃气直接进入用户燃气表的危害,比较了采用先进的进口调压器、在调压器前安装快速切断阀、采用双回路调压器加快速切断阀、在家用燃气表前装设超欠压自动切断阀等预防措施的优缺点,提出了其适用场所。
The comparison is made of imported isolating etc. The harm of direct entrance into service meter for advan regulator, installing valve, installing application sites medium pressure gas is analyzed. A tages and defects among protective measures, fast isolating valve in front of regulator, using excessive underpressure automatic isolating valve of the measures are put forward. including adopting advanced two-circuit regulator plus fast in front of domestic gas meter
