介质的腐蚀使一般金属阀门,甚至包括不锈钢阀门,都不能满足生产需要,有的阀门因耐腐蚀性不好,常使管路被迫停产检修,缩短更换周期,有的又因耐腐蚀阀门的质量不稳定,大量的有害介质外溢,不仅浪费了宝贵的原料,还有损于操作人员的身体健康。为此,我厂近年来在不断吸取各类防腐蚀阀门优点的基础上,利用多种材质,研 Corrosion of the medium so that the general metal valves, including stainless steel valves, can not meet the production needs, and some valves due to poor corrosion resistance, often forced to stop production line maintenance, shorten the replacement cycle, and some because of corrosion-resistant valve Unstable quality and massive outflow of harmful agents not only waste precious raw materials, but also harm the health of operators. To this end, I plant in recent years continue to absorb all kinds of anti-corrosion valve based on the advantages of using a variety of materials, research
