是□ 否□

2.温度表的拆装

是□ 否□

压力表拆装

1. 拆卸压力表,关闭压力表下端阀门,放散后,缓慢、平稳拧下压力表。

是□ 否□

2. 确认压力表下端阀门无内、外漏后,用胶带密封出气口防止杂物进入,拆卸压力表作业完成。。

是□ 否□

3.安装压力表,,检查安装口无杂物,选择相对应的校验后的压力表。

是□ 否□

4.缓慢、平稳拧紧压力表,打开正下端阀门,检漏合格后,观察压力表数值,安装压力表作业完成。

是□ 否□

5.与自动显示数值对比,数值一致压力表安装作业结束。

是□ 否□

7 .   安全注意事项和应急措施

7.1每年有计划校验安全阀,有备用品,如果没有足够的合格安全阀备用,在校验时应首先保证生产安全,可以分多次校验。

7.2安全阀铅封应受到保护,严禁人为破坏。发现铅封损坏,应随时上报,等待处理。

7.3 操作过程中根部阀出现泄漏,应及时封堵。

7.4拆安全阀先放空压力,保证无残液和压力。
