汞是一种剧毒的化学药品。以前我厂使用的流量计,百分之五十是有汞的差压计。长期以来仪表工在检修中,由于汞的外漏造成污染和中毒现象,一直是一个老大难问题。1970年前后就有10人因受不同程度的汞中毒,曾一度使仪表检修工作几乎停顿。自从深入批林整风尤其是批林批孔运动开展以来,我厂仪表车间广大革命职工,高举“鞍钢宪法”的旗帜,广泛发动群众,开展技术革新运动,大搞内外三结合,向开封化肥厂和上海无汞协助组学习,并且得到上海橡胶十厂,上海中国弹簧厂的大力支持,在原有浮子式差压计的基础上,利用橡胶波纹管及平衡弹簧作为平衡元件并加以改进,从 Mercury is a highly toxic chemical. In the past I used the flowmeter, 50% is a mercury differential pressure gauge. For a long time instrumentation workers in the overhaul, due to leakage of mercury pollution and poisoning, has always been a chronic problem. Around 1970, 10 people had halted the overhaul of the instrument once due to different degrees of mercury poisoning. Since the in-depth Linlin rectification campaign, especially the Linlin bailong campaign, a large number of revolutionary workers in the instrumentation workshop of our factory hold high the banner of “Ansteel Constitution”, mobilize the masses extensively, conduct technological innovation campaigns, And Shanghai mercury-free assistance group to learn, and get the support of Shanghai Rubber Factory 10, Shanghai China Spring Factory, based on the original float-type differential pressure gauge, the use of rubber bellows and balance spring as the balance of components and to improve, from
