                衬氟截止阀的安装及注意事项

                发布时间:2014-03-03  来源:福建阀门  编辑:标光阀门

                  衬氟截止阀顾名思义是为了提高耐腐蚀而设计的,是一种采用强制性密封的阀门,所以衬氟截止阀只有◥两种模式,要么全开,要么全关,是绝对不允许作为调节或者节流的阀门。衬氟截止阀的结构分为三种结构形式,其中直通式是较为╱常见的一种结构流体、阻力较大。

                  衬氟截止阀的安装及注意事项:

                  1、首先在安装过程中需要先注意的是校对↙截止阀的一些标志是否跟当前安装的产品∏相同(需要校对的如阀门的通径、材料等等)

                  2、安装鸿彩快三彩票网时务必要将阀门尽量保持在水平的福彩快3彩票官网下载情况下安装々,让阀杆保持向上的方向。如果是在歪斜的情况◇下安装并且使用衬⌒氟截止阀,将会不∩利于手轮的起吊。

                  3、如果与衬氟︼截止阀相连接的两端都是金属的密封面就需要加上塑料的密封垫片。

                  4、安装完成时需要对管道进行试验并且使得阀门处于全开的╱状态。
