The materials are carbon steel, stainless steel and Cr18Ni12Mo2Ti(316). The common characters of the valves are short in service life, easy to leak internally and externally. The internal leakage causes valve difficult to block and control so that it has to add more blank covers somewhere during carbonizing. The mother liquid spills over and corrodes the equipments around and external leakage increases the difficulties of the site management as well as the costs of production, environmental protection problem is difficult to solve completely.The mediums increases to run away, spill over, drop and leak out , for the valves are frequently examined and repaired. The management, operators and repairmen of alkali enterprises are aware of the inconveniences for the problems of valves. The valves special for soda industry and control valves made by Shanghai Fisher Valve Manufacture Co., Ltd. are now used in the great majority of domestic soda industry enterprises . The efficiency is obvious that not only reducing labor intensity to workers, but also solving some environmental protection problem. Valve does not belong to key equipment in united alkali and ammonia alkali production plants and is often neglected during designing, operating and production. But its benefit potential in economy and environment protection will find expression in normal production and management.纯碱专用阀(联碱)使用位置选型建议(供参考) Applicationof Special Valve for Soda Industry inUnitedAlkali Enterprises(For Reference Only) 系统名称系统名称 System相关位置相关位置 ApplyPosition拟选阀门拟选阀门 Suggest Valve备注备注 NoteMII 系统系统 MII System母 II 泵进出口阀 Entrances and outlets that pump II of mother solution纯碱专用 O 形阀 “O” type ball valve for soda盐析排放阀 Salt out valve纯碱专用偏心阀 O 形阀 Eccentric valve,“O” type ball valve for soda 盐析取出阀 Salt out take up valve纯碱专用偏心阀 O 形阀 Eccentric valve,“O” type ball valve for soda 逆料泵进出口阀 Entrances and outlets valve that refluence pump纯碱专用 O 形阀 “O” type ball valve for sodaMII 吸氨器液相阀门 Liquid valve of M II absorb ammonium set纯碱专用偏心阀 V 形阀 O 形阀 Eccentric valve,“V”type ball valve,“O” type ball valve for soda上海费希尔阀门制造有限公司SHANGHAI FISHER VALVE MANUFACTURE CO.,LTD. 销售公司地址：上海普善路 128 弄 8 号 1003 室邮编：200070 Sales CompanyAdd:Room 1003 No.128-8 Pushan RoadShanghai 200070 P.R.
