体,叫做刚性闸板;也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。闸阀关闭时,密封面可以只依靠介质压力来密封,即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封。大部分闸阀是采用强制密封的,即阀门关闭时,要依靠外力强行将闸板压向阀座,以保证密封面的密封性。闸阀的闸板随阀杆一起作直线运动的,叫升降杆闸阀亦叫明杆闸阀。通常在升降杆上有梯形螺纹,通过阀门顶端的螺母以及阀体上的导槽,将旋转运动变为直线运动,也就是将操作转矩变为操作推力。开启阀门时,当闸板提升高度等于阀门通径的1:1倍时,流体的通道完全畅通,但在运行时,此位置是无法监视的。实际使用时,是以阀杆的顶点作为标志,即开不动的位置,作为它的全开位置。为考虑温度变化出现锁死现象,通常在开到顶点位置上,再倒回1/2-1圈,作为全开阀门的位置。因此,阀门的全开位置,按闸板的位置即行程来确定。有的闸阀,阀杆螺母设在闸板上,手轮转动带动阀杆转动,而使闸板提升,这种阀门叫做旋转杆闸阀或叫暗杆闸阀。
闸阀的优点如下:
1、流动阻力小。阀体内部介质通道是直通的,介质成直线流动,流动阻力小。
2、启闭时较省力。是与截止阀相比而言,因为无论是开或闭,闸板运动方向均与介质流动方向相垂直。
3、高度大,启闭时间长。闸板的启闭行程较大,降是通过螺杆进行的。
4、水锤现象不易产生。原因是关闭时间长。
5、介质可向两侧任意方向流动,易于安装。闸阀通道两侧是对称的。
6、结构长度(系壳体两连接端面之间的距离)较小。
7、密封面易磨损,影响使用寿命。启闭时,闸板与阀座两个密封面相互摩擦滑动,要介质压力作用下易产生擦伤磨损,影响密封性能,缩短使用寿命。
8、价格较贵。接触密封面较多,加工较复杂,特别是闸板座上的密封面不易加工,而且零件较多。形体简单,结构长度短,制造工艺性好,适用范围广。
闸阀的缺点如下:
1、密封面之间易引起冲蚀和擦伤,维修比较困难。
2、外形尺寸较大,开启需要一定的空间,开闭时间长。
3、结构较复杂。
闸阀安装与维护
1、手轮、手柄及传动机构均不允许作起吊用,并严禁碰撞。
2、双闸板闸阀应垂直安装(即阀杆处于垂直位置,手轮在顶部)。
3、带有旁通阀的闸阀在开启前应先打开旁通阀(以平衡进出口的压差及减小开启力)。
4、带传动机构的闸阀,按产品使用说明书的规定安装。
5、如果阀门经常开关使用,每月至少润滑一次。
6、闸阀是作为截止介质使用,在全开时整个流通直通,此时介质运行的压力损失**小。
7、闸阀通常适用于不需要经常启闭,而且保持闸板全开或全闭的工况。
8、闸阀不适用于作为调节或节流使用。对于高速流动的介质,闸板在局部开启状况下可以引起闸门的振动,而振动又可能损伤闸板和阀座的密封面,而节流会使闸板遭受介质的冲蚀。
