安全閥結(jié)構(gòu)主要有兩大類：彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要，又有一種脈沖式安全閥，也稱為先導(dǎo)式安全閥，由主安全閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時(shí)，輔助閥先開啟，介質(zhì)沿著導(dǎo)管進(jìn)入主安全閥，并將主安全閥打開，使增高的介質(zhì)壓力降低。</span><span style="font-size:12px;">安全閥的排放量決定于閥座的口徑與閥瓣的開啟高度，也可分為兩種：微啟式開啟高度是閥座內(nèi)徑的（1/20）～（1/40），全啟式是（1/3）～（1/4）。</span> </p> <p> <br /> </p><p> 化工行業(yè)主要采用不銹鋼閘閥、截止閥、止回閥；冶金行業(yè)主要采用低壓大口徑蝶閥、氧氣截止閥和氧氣球閥；城市建設(shè)部門主要采用低壓閥，如城市自來水管道主要采用大口徑閘閥，樓寓建設(shè)主要采用中線蝶閥，城市供熱主要采用金屬密封蝶閥； </p> <p> 輸油管線主要采用平板閘閥和球閥； </p> <p> 制藥行業(yè)主要采用不銹鋼球閥；食品行業(yè)主要采用不銹鋼球閥等。 </p> <p> 核電行業(yè)，閥門在這個(gè)行業(yè)作為核電設(shè)備的基礎(chǔ)設(shè)備，大致占有5-10%的容量。 </p> <p> <p> 中國(guó)將繼續(xù)其核電發(fā)展規(guī)劃，在2015年和2020年核電裝機(jī)容量分別達(dá)到40GW和75GW，中國(guó)將于2012年中期前后重啟新核電項(xiàng)目的審批。所以在這個(gè)領(lǐng)域要不斷的推出新產(chǎn)品、新設(shè)備來滿足市場(chǎng)需求。 </p> <p> <br /> </p> <p> <br /> </p>

此外，隨著使用要求的不同，有封閉式和不封閉式。封閉式即排出的介質(zhì)不外泄，全部沿著規(guī)定的出口排出，一般用于有毒和有腐蝕性的介質(zhì)。不封閉式一般用于無毒或無腐蝕性的介質(zhì)。 </p> <p> 安全閥是啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過規(guī)定值時(shí)，通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值的特殊閥門。安全閥屬于自動(dòng)閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規(guī)定值，對(duì)人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。注安全閥必須經(jīng)過壓力試驗(yàn)才能使用。
