发电厂维修时常因为系统在线运行而阀门关闭不严,造成下游介质泄漏影响焊接作业。在无法使用常见的止漏、堵漏方法的情况下,利用阀门填料函进行分流,是一种在一定条件下消除阀门内漏导致下游管道焊口渗水的有效方法。
Power plant maintenance often because the system is running online and the valve is not strict, resulting in leakage of downstream media affect welding operations. In the case that the common method of sealing and plugging can not be used, the use of a valve stuffing box for shunting is an effective way to eliminate the internal leakage of the valve under certain conditions and lead to the seepage of the downstream pipe weld.
