系列先导式水击泄压阀
Published: 2012-10-31 | Browse: 2019 【Close this page
产品简介:
系列先导式水击泄压阀是专门设计用于控制长输液体管道水击压力的重要安全设备。长输管道因意外突然停泵、阀门紧急关断等流动突变均可能产生管路水击压力,当水击压力超过设定压力时,水击泄压阀迅速开启泄压,避免出现因超压引起泄漏、管道破裂等故障,可广泛用于各种长输液体管道及其他类似场合水击压力的控制。
产品特点:
• 设定压力校验接口,可在线进行设定压力校核,提高保障安全性能;
• 主阀采用轴流式阀体结构,泄放量大,采用较小规格或更少阀门即可满足系统要求,经济性好;
• 开启迅速,可控制其关闭速度,无撞击缓慢关闭,防止二次水击;
• 先导阀与主阀采用集成安装,自动感应阀前水击压力,由管线压力操作,无需配备操作能源;
• 主阀采用软密封设计,密封性好,高、低压状态均可实现可靠密封;
• 自带过滤器提高了先导阀的工作可靠性;过滤器采用法兰连接,清洗和更换滤芯更方便。
