闸阀 用闸板作启闭件并沿阀座轴线垂直方向移动，以实现启闭动作的阀门。闸阀的主要优点是流道通畅，流体阻力小，启闭扭矩小；主要缺点是密封面易擦伤，启闭时间较长，体形和重量较大。闸阀在管道上的应用很广泛,适于制造成大口径阀门。闸阀通常用于截断流体,不宜用于调节流量。因为当闸阀处于半开位置时，闸板会受流体冲蚀和冲击而使密封面破坏，还会产生振动和噪声。 闸阀按闸板的结构不同分为楔式和平行式两类。楔式闸板有3种结构：单闸板的结构（图1）较简单，但楔角的加工精度要求较高，易发生卡紧、擦伤现象；双闸板（图2a）的结构对楔角精度要求较低，闸板不易楔死，但结构较复杂；弹性闸板（图2b）兼有单闸板和双闸板的优点，能避免它们的缺点，因而应用较广泛。它的结构特点是在闸板的周边上有一道环形槽，使闸板具有适当的弹性。平行式闸阀通常采用双闸板结构（图2c）；特殊用途的闸阀，如长距离输油、输气的管道上用的大口径闸阀因清扫阀门和管道的需要而采用单闸板结构。 闸阀还可按阀杆结构和运动方式分为明杆闸阀和暗杆闸阀。明杆闸阀的特点是阀杆带动闸板一起升降，阀杆上的传动螺纹暴露于阀体外部。因此，可根据阀杆的运动方向和位置直观地判断阀门的启闭位置，而且传动螺纹便于润滑和不受流体腐蚀，但它要求有较大的安装空间。与此相反,暗杆闸阀的传动螺纹位于阀体内部,在启闭过程中，阀杆只旋转而不移动（闸板在阀体内上下移动）。因此，阀门开启时阀的高度尺寸小，仅需要较小的安装空间。暗杆闸阀通常在阀盖上方装设开关位置指示器，它适用于船舶、管沟等空间较小和粉尘含量大的环境。
