机械行业标准《金属硬密封提升式旋塞阀》编制说明

1、前言

根据全国阀门标准化技术委员会【2008】阀标委秘第 24 号文,起草机械行业标准《金属硬密封提升式旋塞阀》。 

2、GAIKUANG

国内目前只有铁制旋塞阀国家标准,铁制旋塞阀只能用于低压工况。金属硬密封提升式旋塞阀是我近年来发展比较快的新型旋塞阀,它采用了先提升后启闭的阀门操作方式,大大减少了旋塞阀的启闭力矩,而且不同于传统旋塞阀采用矩形缩径通道,该阀门通常采用圆形通道,使旋塞阀的流体阻力大大减少,金属硬密封提升式旋塞阀兼有球阀与闸阀的有点,能用于高温、高压工况,大大扩展了旋塞阀的使用范围。该产品具有良好的市场前景。但是目前国内外还没有相应的产品标准。为了更好的生产和推广应用金属硬密封提升式旋塞阀,为了更好的规范金属硬密封提升式旋塞阀的设计与性能,同时使产品的设计更加标准化和规范化,迫切需要制定相应的产品标准。
