我厂四台直径5.3米的蝴蝶阀伸缩节,其止漏盘根原采用22×22五层编织油浸麻盘根由压环压紧。投入运行7～8年后漏水逐年扩大,从伸缩节缝隙中喷射出的水威协电气设备的运行。尤其高水头运行时漏水更为严重,影响电站的安全生产。为此,曾多次按原设计更换新油麻盘根,但仍没有使漏水消除。在处理过程中发现,伸缩节的盘根填
I plant four 5.3-meter-diameter butterfly valve telescopic section, the original leak-proof disk using 22 × 22 five layers of woven oil immersed pan root pressure ring compression. Put into operation 7 to 8 years after the leakage has expanded each year, from the telescopic section of the gap in the water spray out of the Association of electrical equipment operation. In particular, high-head running more serious leakage, affecting the safety of power plants. For this reason, the new yam ramie packing has been replaced on many occasions according to the original design but no leakage has yet been eliminated. Found in the process of treatment, expansion joint packing packing
