盐酸工况用加压湿法冶金特种开关阀门的研制

Development of hydrochloric acid special pressure switch valve with pressurized hydrometallurgy

针对新型酸法提取工艺的酸性流体介质的特性,以及温度、压力等要求,开展了一种耐冲刷及加压的湿法冶金特种开关阀门的研制.通过对该特种阀门的结构方案设计及优化,研制出盐酸工况用加压湿法冶金特种开关阀门,并且通过DN150开关型特种阀门样机进行了一系列试验验证.结果表明,所研制的特种开关阀门能满足要求,解决了盐酸工况用加压湿法冶金工艺系统用120~160℃高温特种阀门的关键技术.

In view of the characteristics of the acid fluid medium of the new acid extraction process, as well as the requirements of temperature and pressure, a kind of special hydrometallurgical switch valve which is resistant to scouring and pressurization was developed. According to the structural design and optimization of the special valve, a special switch valve for hydrometallurgy in hydrochloric acid working condition was developed, through the DN150 switch type special valve prototype has carried out a series of research experiments. The test results show that the developed special switching valve can meet the requirements. The key technology of 120 160 degree special valve used in pressurized hydrometallurgical process system for hydrochloric acid working condition is solved.
