style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <img src="/uFile/90212/image/2019928152149544.jpg" alt="" /> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 閥門泄漏的大多數都是由于填料泄漏造成的。閥門的填料一般都會選用石棉填料、高壓石棉填料、帶金屬絲石棉填料、碳纖維填料、柔性石墨填料、聚乙烯填料、芳綸填料等。特種閥門也有選用金屬填料的，所以在選擇閥門填料必須根據工藝操作特點合理選用。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0000FF;"> 如選用不當或安裝不正確，必將引起閥門填料密封的泄漏：</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 如在高溫條件下石棉填料會被燒損、老化變硬，失去彈性，孔隙增大; </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 腐蝕性介質會腐蝕閥桿，在閥桿下部周圍形成麻坑; </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 填加量不足、初壓不緊，壓蓋在后期就沒有壓縮量; </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 填料加量太多，壓蓋沒有壓到填料函里; </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 填料部分外露或料壓法不正確，就會從填料接縫中漏出介質等，以上提到的這些因素都會造成閥門泄漏。若要保證閥門填料嚴密可靠，就必須正確掌握填料的要求及安裝方法，下面就為大家詳細解答一下。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0000FF;">填料的正確安裝方法：</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 挖沙船閥門在加填料前必須將填料箱清理干凈;同時閥桿應光滑無蝕坑;先在填料箱內加少量機油鉛粉，如用鉛粉石棉紡織填料時，尺寸應稍大于填料箱間隙，填料時應圈一圈地加入，每加一圈應壓緊一次，壓入后填料箱應有3～5mm余量，壓蓋與填料箱的間隙應均勻不偏，使壓蓋有再次壓縮的余地，一般可保持10～15mm。。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 介質溫度在<u>450℃以下的高溫閥門，可用鉛粉石棉填料和鉛填料的混合填料</u>。其安裝方法是： </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 在壓好兩圈高壓石棉填料后，壓一圈或兩圈鉛填料，再壓兩囲高壓石棉填料，再壓圈鉛填料，然后用兩圈高壓石棉填料封死，上緊壓蓋。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 鉛填料盡量是車制成圓筒形，厚度和石棉填料相等。壓填料時應將閥門手輪及支架拆掉，從絲桿頂端套入，一層層壓緊。 </p>
