法蘭的泄漏閥門(mén)的法蘭密封主要是依靠連接螺栓的預(yù)緊力，通過(guò)墊片達(dá)到足夠的密封比壓，來(lái)阻止被密封壓力流體介質(zhì)的外泄。它泄漏的原因有很多方面，密封墊片的壓緊力不足，結(jié)合面的粗糙度不符合要求，墊片變形和機(jī)械振動(dòng)等都會(huì)引起密封墊片與法蘭結(jié)合面密合不嚴(yán)而發(fā)生泄漏。另外螺栓變形或伸長(zhǎng)，墊片老化，回彈力下降，龜裂等也會(huì)造成法蘭面密封不嚴(yán)而發(fā)生泄漏。法蘭泄漏還有不可忽視的人為因素，如密封墊片裝偏，使局部密封比壓不足緊力過(guò)度，超過(guò)了密封墊片的設(shè)計(jì)極限，以及法蘭緊固過(guò)程中用力不均或兩法蘭中心線偏移，造成假緊現(xiàn)象等都容易發(fā)生泄漏。閥體的外漏和原因閥體的外漏主要原因是由于閥門(mén)生產(chǎn)過(guò)程中鑄造或鍛造缺點(diǎn)所引起的，比如砂眼，氣孔、裂紋等，而流體介質(zhì)的沖刷和氣蝕也是造成閥體泄漏的常見(jiàn)因素。3帶壓堵漏的原理及優(yōu)點(diǎn)帶壓堵漏的原理帶壓堵漏的原理就是以液態(tài)介質(zhì)在動(dòng)態(tài)條件下，固態(tài)密封材料的密封機(jī)理為基本依據(jù)。方法是在泄漏部位裝設(shè)專(zhuān)用設(shè)備，利用密封部位和專(zhuān)用設(shè)備之間形成的腔室，采用專(zhuān)用的高壓注膠工具將密封膠注入腔室，并充滿(mǎn)整個(gè)腔室空間，使密封膠的擠壓力與泄漏介質(zhì)的壓力相平衡，建立一個(gè)新的密封結(jié)構(gòu)來(lái)堵塞泄漏孔隙各通道。將流體的溫度載荷作用在閘閥的內(nèi)壁面，外壁面暴露在空氣中，對(duì)外壁面施加相應(yīng)的對(duì)流換熱邊界條件。</p><div
