产品简介

。闸阀闸体内部介质通道是直通的，介质流经闸阀时不改变其流动方向，因而流动阻力较小。
（2）启闭较省力。启闭时闸板运动方向与介质流动方向相垂直。

详细介绍

低温闸阀闸阀是zui常用的截断阀之一，主要用来接通或截断管路中的介质，不适用于调节介质流量。闸阀适用的压力、温度及口径范围很大，尤其适用于中、大口径的管道。闸阀的主要优点：（1）流体阻力小。闸阀闸体内部介质通道是直通的，介质流经闸阀时不改变其流动方向，因而流动阻力较小。（2）启闭较省力。启闭时闸板运动方向与介质流动方向相垂直。与截止阀相比，闸阀的启闭较为省力。（3）介质流动方向一般不受限制。介质可从闸阀两侧任意方向流过，均能达到接通或截断的目的。便于安装，适用于介质的流动方向可能改变的管路中。
