閘閥是zui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(jié)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(yōu)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(jīng)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。 | | | | 主要零件材料及性能規(guī)范 | | 主要零部件 | 閥體閥蓋 | 碳鋼 | 鉻鎳鈦不銹鋼 | 鉻鎳鉬鈦不銹鋼 | 超低碳不銹鋼 | 鉻鉬合金鋼 | 低溫碳鋼 | | 閘板閥座 | 碳鋼堆焊硬質合金或不銹鋼 | 鉻鎳鈦不銹鋼堆焊硬質合金 |
