泄压阀结构主要有两大类:弹簧式和杠杆式。 宋体;mso-font-kerning:0pt" lang="EN-US">
弹簧式是指阀瓣与阀座的密封靠弹簧的作用力。

杠杆式是靠杠杆和重锤的作用力。 宋体;mso-font-kerning:0pt" lang="EN-US">
随着大容量的需要,又有一种脉冲式泄压阀,也称为先导式泄压阀,由主泄压阀和辅助阀组成。当管道内介质压力超过规定压力值时,辅助阀先开启,介质沿着导管进入主泄压阀,并将主泄压阀打开,使增高的介质压力降低。

如果主管道水流压力继续增加,导阀开启量也随之加大 宋体;mso-font-kerning:0pt"> 使得主阀上腔与下腔的压差更大,主阀开启量也越大,系统泄压更快。反之,如果主管道水流压力减小 宋体;mso-font-kerning:0pt" lang="EN-US">(如室内消火栓使用个数增加或开启喷头个数增多时 宋体;mso-font-kerning:0pt" lang="EN-US">),导阀控制室压力随之减小,导阀开启量变小。主阀上腔压力增大,主阀阀瓣询下关小,使主管道水流压力稳定在系统设计。

宋体;mso-font-kerning:0pt">特点
宋体;mso-font-kerning:0pt" lang="EN-US">1、准确且保持不变的安全稳定压力,一旦超压,泄压阀能充分打开及时泄压。 宋体;mso-font-kerning:0pt" lang="EN-US">
宋体;mso-font-kerning:0pt" lang="EN-US">2、关闭速度可调,消除压力波动。 0pt" lang="EN-US">
宋体;mso-font-kerning:0pt" lang="EN-US">3、隔膜传动机构将操作滞后现象减小到最小。
宋体;mso-font-kerning:0pt" lang="EN-US">4、它可安装在任何位置,不用改变压力设定值或从管路上拆除就可进行维修和检查。
