                          閥門內漏的原因和處理方法

                          內漏的原因:


                          1.關閉不嚴;


                          2.結合面損傷;


                          3.閥芯與閥桿間隙過大,造成閥芯下垂或接觸不好;


                          4.密封材料不良或閥芯卡澀。


                          如何處理:


                          1.改進操作,重新開啟或關閉;


                          2.閥門解體,閥芯、閥座密封面重新研磨;


                          3.調整閥芯與閥桿間隙或更換閥瓣;


                          4.閥門解體,消除卡澀;


                          5.重新更換或堆焊密封圈
