1、前言

根據全國閥門標準化技術委員會【2008】閥標委秘第 24 號文,起草機械行業標準《金屬硬密封提升式旋塞閥》。

2、概況

國內目前只有鐵制旋塞閥國家標準,鐵制旋塞閥只能用于低壓工況。金屬硬密封提升式旋塞閥是我近年來發展比較快的新型旋塞閥,它采用了先提升后啟閉的閥門操作方式,大大減少了旋塞閥的啟閉力矩,而且不同于傳統旋塞閥采用矩形縮徑通道,該閥門通常采用圓形通道,使旋塞閥的流體阻力大大減少,金屬硬密封提升式旋塞閥兼有球閥閘閥的有點,能用于高溫、高壓工況,大大擴展了旋塞閥的使用范圍。該產品具有良好的市場前景。但是目前國內外還沒有相應的產品標準。為了更好的生產和推廣應用金屬硬密封提升式旋塞閥,為了更好的規范金屬硬密封提升式旋塞閥的設計與性能,同時使產品的設計更加標準化和規范化,迫切需要制定相應的產品標準。
