科普知识:贯流式止回阀的主要参数

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。

阀门型号:GL41W/H/Y,ZLH41W/H/Y等
阀体材质:WCB,304,316,CF8,CF8M,CF3,CF3M及双相不锈钢等
尺寸范围:DN25-DN350等
压力范围:1.0-10.0Mpa等
耐温范围:-60℃≤t≤425℃
设计标准:国标GB
连接方式: 法兰、对夹、丝口或焊接。
适用介质: 水、油品、气体、蒸汽等。
应用领域:机械设备、化工设备、通用零部件、工业设备、给排水设备、造纸设备、制药设备、通用设备、石化设备、电力设备、治金粉末设备采矿设备,市政、电子工业等。
