本项目产品是一种主要石油、天然气工业管道用锻钢全焊接球阀,为保证零泄漏,采用整体式双向密封球阀阀座,改变了传统球阀组合式的阀座结构且具有双活塞效应,能满足双隔离和排放的DIB功能要求,比传统的双截断和排放的DBB结构有明显的启闭力矩小、耗材少的技术优势,显著提高了阀座和阀体之间的密封效果和阀门的使用寿命。 The project product is a kind of all-welded ball valve with forged steel used in the main oil and gas industry. To ensure zero leakage, the integral two-way sealed ball valve seat is adopted to change the traditional ball valve combined seat structure and has double piston effect. DIB function to meet the requirements of double isolation and emissions than the traditional dual-cut DBB structure and emissions have obvious opening and closing torque, the advantages of less consumables, significantly improve the sealing effect between the valve seat and the valve and the Service life.
