硬密封闸阀.doc

硬密封闸阀 、挤压开裂；阀门在制造过程中，难以保证蝶板在阀体腔中的同心度，往往以过度挤压的方式解决密封问题，从而影响了阀门的使用寿命；立式蝶阀阀轴与轴套的加工精度及止推方式失调，导致蝶板晃动与下垂，形成了渗漏；蝶阀在安装施工过程中胶圈受损，影响了密封性。一些厂家针对上述问题进行了以下的改进：胶圈定点外协生产，加强质量把关，通常用于供水行业的阀门，选用三元乙丙橡胶和丁睛橡胶而天然橡胶用的不多，严禁掺和再生胶；湖北某厂对蝶板上的密封胶圈的整块压板改成短块燕尾拼装连接，以调节各部位压板的挤压程度来平衡蝶阀使用寿命，但这种调节技巧也一、产品国标电动法兰闸阀的详细资料：产品名称：国标电动法兰闸阀产品特点：国标电动法兰闸阀价格,国标电动法兰闸阀厂家,国标电动法兰闸阀报价。二、电装型号规格主要尺寸：1.6MPaDNLDD1D2bn-d电装型号L1HDO凸面法法RFZ940HZ940YZ940WZ940FZ941HZ941YZ941WZ941F16C16P16R16I4020014511085164-18DZW1059059536550250160125100164-18DZW1059065336565265180145120184-18DZW1059066536580280195160135208-18DZW15590725365100300215180155208-18DZW20590787365125325245210185228-18DZW20590934365150350280240210248-23DZW205909553652004003352952652612-23DZW3059011053652504504053353203012-25DZW3081013434703005004604103753012-25DZW4581015164703505505204704353416-25DZW9081016784704006005805254853616-30DZW12083018495504506506405855454020-30DZW12083019375505007007056506084420-34DZW18083022345506008008407707184820-41DZW25087024323207009009108407885024-41DZW2508702489320800100010209508985224-41DZW350117026435709001100112010509985428-41DZW50011702935570100012001255117011005628-18DZW50011703410570三、电装型号规格主要尺寸

管道，不易堆积杂物，确保密封可靠，使流体畅通无阻。阀瓣整体包装阀瓣采用高品质的橡胶进行整体内、外包装，欧州一流的橡胶硫化技术使得硫化后的阀门能保证精确几何尺寸，且橡胶与球墨与铸铁阀瓣接覆牢靠，不易脱落及弹性记忆佳。精铸阀体阀体采用精密封铸造，精确的几何尺寸使得阀体内部无
