                詳細描述

                低溫閘閥
                閘閥是最常用的截斷閥之一,主要用來接通或截斷管路中的介質,不適用于調節介質流量。閘閥適用的壓力、溫度及口徑范圍很大,尤其適用于中、大口徑的管道。
                閘閥的主要優點:
                (1)流體阻力小。閘閥閘體內部介質通道是直通的,介質流經閘閥時不改變其流動方向,因而流動阻力較小。
                (2)啟閉較省力。啟閉時閘板運動方向與介質流動方向相垂直。與截止閥相比,閘閥的啟閉較為省力。
                (3)介質流動方向一般不受限制。介質可從閘閥兩側任意方向流過,均能達到接通或截斷的目的。便于安裝,適用于介質的流動方向可能改變的管路中。
