可以在拆下的螺栓上直接安放螺栓**注劑接頭，一般不少于兩個。安裝注劑接頭時應(yīng)松開一個螺母，安裝好注劑接頭，迅速重新擰緊螺母，然后再安裝另外的注劑接頭，不能同時將所需接頭螺母松開，以免造成墊片上的密封比壓明顯下降，泄漏量增加，甚至?xí)霈F(xiàn)泄漏介質(zhì)將墊片吹走，導(dǎo)致無法彌補的后果。如果原來泄漏量較大，可用G形夾子來維持密封比壓的均衡，蕭縣減壓閥門供應(yīng)商，安裝完注劑螺栓后，用工具將直徑或略小于泄漏法蘭間隙的銅絲嵌入到法蘭間隙中，同時將法蘭的外緣沖出唇口，使銅絲固定后在法蘭間隙內(nèi)，蕭縣減壓閥門供應(yīng)商，這樣就組成新的密封腔。然后可連接高壓注劑***進行動態(tài)密封作業(yè)，注劑方向應(yīng)從泄漏點相反處依次進行，終點應(yīng)在漏點附近。2003年6月，攀鋼發(fā)電廠＃1機低壓聯(lián)通管垂直法蘭面泄漏就是采用這種堵漏技術(shù)解決了聯(lián)通管法蘭面的泄漏問題，避免了一次停機***的發(fā)生。鋼帶圍堵法當(dāng)兩法蘭間隙稍大且不超過8mm，介質(zhì)壓力小于，可采用鋼帶圍堵法進行運態(tài)密封作業(yè)。它對兩法蘭同軸度有較高要求，對法蘭間隙均勻程度要求不高。鋼帶一般選用，蕭縣減壓閥門供應(yīng)商，寬度20--30mm即可，制作時可采用焊接或鉚接，兩接頭下方需加設(shè)過渡墊片，根據(jù)法蘭尺寸確定安裝注劑接頭的數(shù)量。安裝鋼帶時，應(yīng)將鋼帶位于兩法蘭的間隙上。溝槽閘閥工作時結(jié)構(gòu)的變形很小，對流體流動狀態(tài)及溫度的變化影響也很小，即單向藕合作用。蕭縣減壓閥門供應(yīng)商</p><div
