我厂6个高压贮液桶的下部,都留有安装玻璃管自动液位计的短接管与直角截止阀。由于此液位计的磁力线圈和小浮子的质量问题,在1979年投产时就未安装。当时将所有角阀关闭,并加堵了盲板。1992年发现4号桶下部盲板腐蚀破损,不断有氨液滴漏,且日甚一日,时值桶内压力0.85MPa,液面为55％。有人提出阀门是关闭的,既使泄漏也不会 I plant the lower part of the 6 high-pressure liquid storage barrel, are left to install a glass tube automatic level gauge short-connected pipe and right-angle stop valve. Due to the quality problems of the magnetic coil and the small float of this level gauge, it was not installed when it came into operation in 1979. At the time, all the angle valves were closed and the blind was added. 1992 found that the lower part of No. 4 barrel blind corrosion damage, there are ammonia drip, and day by day, when the barrel pressure 0.85MPa, the liquid level is 55%. It was suggested that the valve is closed, even if the leak will not
