压力表是锅炉的重要安全附件,是锅炉内外部检验和点火升压检验的必检项目。从我市近年的检验情况看,锅炉压力表的三通铜旋塞咬死、堵塞、开裂及跑冒滴漏现象普遍。据不完全统计1992年发现压力表三通铜旋塞咬死、堵塞、开裂占30%以上,跑冒滴漏占50%以上。这对锅炉的安全运行是个潜在的危险。从我市现有安装、使用的蒸汽锅炉压力表的安装情况分析,绝大多数装在锅炉前端的上方或顶部,距地面铅直高3m以上,既无扶梯又无平台,而且压力表和管路均固定。见图1a所示,这种安装方式是欠妥的,司炉人员反响很大,归纳起来有
Pressure gauge is an important safety annex of the boiler, the boiler internal and external inspection and boost test will be seized items. Judging from the inspection situation in recent years in our city, the three-way copper cock of the manometer of the boiler is biting dead, clogging, cracking and dripping and leaking are common. According to incomplete statistics, it was found in 1992 that the pressure gauge three-way copper cock seized, blocked and cracked by more than 30%, accounting for more than 50% of run-down dribbles. This is a potential danger to the safe operation of the boiler. From the city’s existing installation, the use of steam boiler pressure gauge installation situation analysis, the vast majority installed in the top or top of the boiler, from the ground above the vertical height of 3m, neither escalator nor platform, and pressure gauge and tube The road is fixed. Shown in Figure 1a, this installation is defective, the stove staff a lot of response, sum up
