H71W对夹升降式止回阀该产品采用对夹式连接,结构紧凑,阀瓣沿着中心定位作 升降运动,由于阀瓣的关闭行程短,并有弹簧加载,关闭速度快,可显著减少水锤现象。对夹升降式止回阀具有体积小、重量轻、动作灵敏、密封可靠、安装方便等特点,特别适合于安装空间受限制的场合采用,H71W单瓣对夹升降式止回阀可适用于水、蒸气、油品、硝酸、醋酸、强氧化性介质等多种介质。
设计制造:JB/T8937
结构长度:JB/T8937
配管法兰:JB/T74
试验与检验:JB/T9092-1999
二、H71(H/W/X/F)不锈钢对夹式止回阀特点:1、具有结构短、体积小、质量轻;
2、阀瓣关闭快速,水锤压力小;
3、流道通畅,流体阻力小;动作灵敏,密封性能好
