由管道设计院设计,抚顺工程机械厂制造的浮球式单向排水阀和新型旋转接头,年前在廊坊市管道局通过技术鉴定。这项成果很好地解决了浮顶油罐排水不畅、浮顶积水、排水管渗漏油和运转不灵等长期困扰的问题,填补了国内浮顶油罐排水专用阀的空白。 Design by the pipeline design institutes, float-type one-way drain valve manufactured by Fushun Engineering Machinery Factory and a new type of rotary joint, passed the technical appraisal in Langfang City Pipeline Bureau years ago. This result solves the long-term problems of poor drainage of floating roof tank, floating water of the floating roof, leakage of oil in the drainage pipe and poor operation, filling in the gap of the domestic special valve for drainage of the floating roof tank.
