电动蝶阀的安装应注意哪些方面
易觅尔 / 2012-09-14

    1、得发在安装前应保持干燥，不可露天存放

    2、安装蝶阀前要检查管道，确保管道内无焊渣等异物

    3、蝶阀阀体手动启闭阻力适中，蝶阀扭矩与所选执行器扭矩匹配。

    4、蝶阀连接用法兰规格正确，管道对夹法兰与蝶阀法兰标准相符。建议使用蝶阀专用法兰，不得使用平焊法兰。

    5、确认法兰焊接无误，蝶阀安装完毕后不得再焊接法兰，以免烫伤橡胶件。

    6、装好的管道法兰要进行对中，并与放入的蝶阀进行对中。

    7、装上所有的法兰螺栓，并用手拧紧，将确认蝶阀与法兰已然对中，然后小心的启闭蝶阀，确保启闭灵活。

    8、将阀门完全开启，用扳手按照对角线次序将螺栓拧紧，无需垫圈，切勿将螺栓拧的过紧，以防造成阀圈的严重变形，启闭扭矩过大。
