吉林局通化机务段在大搞炉外软水的斗争中,碰到的问题之一就是没有大口径(Dg100)耐酸阀门,怎么办?是伸手向国家要还是自己创造。广大工人、技术人员、干部在毛主席“独立自主,自力更生”的教导鼓舞下,狠批了“洋奴哲学”“爬行主义”打破了洋框框,坚持走自己工业发展道路。经过七次试验,终于用塑料板、管做出了Dg100的塑料隔膜阀,经过二年多的实践,证明完全合乎要求。这种阀门,材料来源易得,造价较低,不要专门高级技工就可以制作,正个阀体较为轻便,它的施工过程是: 1.阀体用10mm塑料板制做(现在用的压力是4.5Kg/cm~2,如果压力需要大些可增加塑料板的厚
One of the problems encountered in the fight for soft water outside the furnace by the Jilin Bureau Tonghua Locomotive Section is that there is no large-diameter (Dg100) acid-resistant valve. What should we do? We must reach out to the country or create it ourselves. Inspired by Chairman Mao’s “independent, self-reliant” teaching, the majority of workers, technicians, and cadres encouraged the “crawler philosophy” and “crawliness” to break the foreign framework and adhere to their own industrial development path. After seven trials, Dg100 plastic diaphragm valves were finally made with plastic plates and tubes. After more than two years of practice, it proved to be completely satisfactory. This kind of valve has easy access to materials and low cost. It can be made without special senior technicians. The valve body is relatively light. Its construction process is: 1. The valve body is made of 10mm plastic plate (the pressure is now used 4.5Kg/cm~2, if the pressure needs to be larger to increase the thickness of the plastic plate
