            型号:H76T1~T8、H71H、H76W、H71W、H76Y、H71T1~T8等
            口径:NPS1?~NPS84、DN40~DN2100
            压力:Class150~Class2500、PN20~PN420
            材质:碳钢、不锈钢、合金钢、双相钢
            应用:石油,化工,天然气,石化,煤化工等行业
            驱动:无(自动)

            对夹式止回阀产品简介

                对夹式止回阀适用于Class150~Class2500、PN20~PN420的各?#27490;?#36335;上,用于截断或?#27833;?#31649;路中的介质。通过选择碳钢、不锈钢、合金钢等阀门材质,超达集团的对夹式止回阀可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。对夹式止回阀采用对夹连接。

                对夹式止回阀由阀体、阀瓣、弹簧等零件组成,采用对夹连接。止回阀不像其他闸阀、球阀、截止阀等阀门需要执行机构带动,对夹式止回阀不同于法兰式止回阀,不需要阀盖。由于阀瓣的关闭行程短,并且有弹簧加载,?#19978;?#33879;减少水锤现象。对夹止回阀主要适用于城?#23567;?#24037;业及高层建筑给水、排水管网上。由于其结构长度比?#35805;?#27490;回阀短,对有安装空间限制的场所较为适用。对夹式止回阀用于纯净管路及工业、环保、水处理、高层建筑给排水管路,阻止介质逆向流动之用。

                止回阀常见故障有①密封面破坏;②杂质附着在止回阀阀瓣密封面。修复密封面和清洗杂质,就能防止倒流。

                超达研制生产的对夹式止回阀具有水锤压力较小,阀瓣行程短、阀瓣轻巧、具有弹簧辅助关闭、关阀速度较快。结构长度较短、体积较小、重量较轻、为阀门的安装、搬运、存放及管道的布置带来较大的便利,并能节约材料、降低造价等特点。

            对夹式止回阀产品特点

            1、结构长度短,其结构长度只有传统法兰止回阀的1/4~1/8

            2、体积小、重量轻、其重量只有传统微阻缓闭止回阀的1/4~1/20

            3、对夹式止回阀的阀瓣关闭快速,水锤压力小

            4、止回阀水平或垂直管道均可使用,安装方便

            5、对夹式止回阀流道通畅、流体阻力小

            6、动作灵敏、密封性能好

            7、阀瓣行程短、对夹式止回阀关阀冲击力小

            8、整体结构、简单紧凑、造型美观

            9、使用寿命长、可靠性高

                超达阀门集团股份有限公司是原浙江超达阀门股份有限公司升级而来,在1998年就通过了ISO9001国?#25163;?#37327;管理体?#31561;现ぁ?/p>
