求翻译：本减压装置是采用调节螺纹杆的长度尺寸来实现取样水的减压，在检修减压装置时要解体清理检查，尤其在机组大修投运后第一次检修要解体清理积在减压装置内的锈物和其它杂物，并检查减压装置的阳、阴螺纹是否完好，“O”型密封圈如有变形和损坏要换新。装配时注意“O”型密封圈不要被挤坏，减压器压盖要扳紧。检修后减压装置的调节螺杆应全部旋入，在投入进逐渐调节至正常，防止因减压装置出口压力过高而影响取样分析和仪表分析，同时在调整减压装置螺杆时要防止螺杆脱出使未经减压的水汽冲出危及不身及设备安全。是什么意思？

The pressure relief device is adjustable in length of threaded rod to size of the sampling water pressure when the pressure relief device you want to access clean break inspection, and, in particular the unit overhaul and repair the first time after dissolution to clean up the pressure relief device

This decompressor is uses the adjustment thread pole the length size to realize the sample water reduced pressure, when overhaul decompressor must disintegrate the cleaning up inspection, throws especially after the unit overhaul transports the first overhaul to have to disintegrate the cleaning up

This decompression device is used regulation thread rod of length size to achieved sampling water of decompression, in overhaul decompression device Shi to disintegration cleanup check, especially in unit overhaul voted games Hou first times overhaul to disintegration cleanup product in decompressio
