贯流式止回阀性能及特点

GLH41H贯流式止回阀采用特殊密封结构,无论阀后压力的高低,阀门都关闭严密,密封性能好。克服了一般止回阀在低背压时密封性能差的缺点。贯流式止回阀采用浮动的阀瓣结构,能自动补偿因安装和使用中磨损所引起的误差,保证密封面紧密贴合,提高了密封性能。
GLH41W不锈钢贯流式止回阀性能及特点:
1. 流线型流道,介质不绕流,阀门流阻小,节省能源。
2. 采用特殊密封结构,无论阀后压力的高低,阀门都关闭严密,密封性能好。克服了一般止回阀在低背压时密封性能差的缺点。
3. 采用浮动的阀瓣结构,能自动补偿因安装和使用中磨损所引起的误差,保证密封面紧密贴合,提高了密封性能。
4. 启闭行程短,并能自动复位无冲击,在较小的流速下,阀门即可全开,关闭时间短。
5. 阀门不受安装位置限制,可以水平、垂直及任意角度安装。
6. 阀门有标准系列和短系列两种结构长度,短系列结构长度特别适合于安装位置较小,结构比较紧凑的装置中。
