具体的试压过程如下:
1.在安装完成后,将球阀的出口端、进口端和安装完成的管路和部件与气源相连接;
2.将气源的压力调节至所需的试验压力,并将压力表校准至0点;
3.打开球阀的调节手柄,将球阀的开关位置调至中间位置,确保球阀闭合;
4.检查球阀的漏气情况,确认无漏气后,将压力调至试验压力;
5.观察球阀的漏气情况,将压力保持在试验压力,持续观察15分钟,确保球阀无漏气;
6.将压力调至0点,打开球阀的调节手柄,将球阀的开关位置调至关闭位置,检查球阀的漏气情况;
7.将压力调至试验压力,持续观察15分钟,确保球阀无漏气;
8.将压力调至0点,关闭球阀的调节手柄,检查球阀的漏气情况;
9.完成球阀试压,记录试压结果,并做好相关记录。
