萨姆森阀门法兰盘及衬垫强度不够怎么办

 关键字：萨姆森阀门              http://www.samson-china.com/

　　萨姆森阀门在安装的时候需要遵循规范，进行必要的质量检验，这样在阀门安装前，做了严密性和耐压强度的试验，就会减少关闭不严、出现漏水、阀门开关不灵活的现象。

　　萨姆森阀门管道连接的法兰盘及衬垫强度不够，连接螺栓短或直径细。热力管道使用橡胶垫，冷水管道采用双层垫或斜面垫，法兰衬垫突入管内。这样会造成法兰盘连接处不严密，甚至损坏，出现渗漏现象。法兰衬垫突入管内，会增加水流阻力。 　　面对这种情况的时候，萨姆森阀门的法兰中间不得放置几个衬垫或斜面垫，连接法兰的螺栓直径比法兰盘孔径宜小于2mm，螺栓杆突出螺母长度宜为螺母厚度的1／2。法兰的衬垫不得突入管内，其外圆到法兰螺栓孔为宜。其管道用法兰盘及衬垫必须满足管道设计工作压力的要求。给排水管道的法兰衬垫，宜采用橡胶垫。采暖和热水供应管道的法兰衬垫，宜采用橡胶石棉垫。 　　以上为大家介绍了萨姆森阀门在安装时需要注意的事项，这样可以帮助大家在使用时能够更好地使用阀门。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱:    sales@whdkm.com原文出处：http://www.samson-china.com/a/xwzx/293.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1606378568787&bpp=4&bdt=275&idt=65&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=7971762356576&frm=23&ife=1&pv=2&ga_vid=2141199789.1606378569&ga_sid=1606378569&ga_hid=537182254&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=7&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=3777779347994354&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.4nhvfvppwpmn&fsb=1&dtd=107" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.4nhvfvppwpmn" data-load-complete="true">
