1.在具有酸、碱、盐或其他腐蚀性液体的管道传输中,有些厂矿安装了不锈钢截止阀,这种阀门的阀座与阀盘一旦被腐蚀或磨损,由于修复起来比较费事,故往往弃旧换新,浪费较大。现介绍一种极为简易的修复方法。 首先将阀盖拆开,把阀盘取出,然后在阀盘上钻孔(与阀座接触的那一面开钻)、攻丝。大阀门可攻M6～M8的丝;小阀门可攻M5的丝。攻丝打孔时钻头直径按式D=d-t选择,式中d为螺纹直径、t
1. In the pipeline with acid, alkali, salt or other corrosive liquids, some factories and mines installed stainless steel stop valve, the valve seat and the valve plate once corroded or worn, as it is more complicated to repair, it is often Abandon old change, waste more. Now introduce a very simple method of repair. First, disassemble the bonnet, remove the valve disc, and then drill the valve disc (the side in contact with the valve seat open), tapping. Large valve can tap M6 ~ M8 wire; small valve can tap the M5 wire. Drilling tapping drill diameter by the type D = d-t choice, where d is the thread diameter, t
