style="text-indent:25px">止回閥，又稱單向閥、逆止閥，在石油化工行業(yè)中應(yīng)用非常普遍，在一些高風(fēng)險(xiǎn)裝置的關(guān)鍵部位如加氫裝置高壓離心泵出口、氫氣壓縮機(jī)出口、高壓系統(tǒng)和低壓系統(tǒng)界區(qū)都安裝止回閥。一些企業(yè)由于在設(shè)計(jì)、選材、使用、檢驗(yàn)、維修等環(huán)節(jié)管理不到位，導(dǎo)致止回閥失效，物料倒流，高壓系統(tǒng)物料向低壓系統(tǒng)反串，引起低壓設(shè)備損壞，或發(fā)生物料泄漏，引發(fā)火災(zāi)、事故。止回閥是存在運(yùn)動部件的設(shè)備，存在損壞可能，必須對止回閥定期進(jìn)行檢驗(yàn)和修理，才能確保其可靠性。一些關(guān)鍵部位的止回閥的重要性不低于安全閥，目前國家標(biāo)準(zhǔn)、企業(yè)的管理制度中對安全閥的檢查和校驗(yàn)都有明確要求，但是沒有對止回閥進(jìn)行定期檢驗(yàn)、維修的制度、規(guī)定、標(biāo)準(zhǔn)。止回閥不在國家強(qiáng)制檢驗(yàn)范圍之內(nèi)，只是列入一般閥門管理。</p><p style="text-indent:25px">止回閥是污水提升機(jī)里一個(gè)很重要的部件，它是控制污水流量和流通的啟閉件，在整個(gè)提升系統(tǒng)中起著至關(guān)重要的作用。它是一種自動閥，主要用于介質(zhì)單向流動的管道上，只允許介質(zhì)向一個(gè)方向流動，當(dāng)介質(zhì)反方向流動時(shí)則依靠介質(zhì)的壓力和自重自動合閥阻止介質(zhì)進(jìn)一步流入集水箱造成污水回流。箱體集成旋啟式止回閥有橡膠密封面，在總箱體內(nèi)部，制造工藝復(fù)雜，難度高，可以有效的降低噪音。普通球型止回閥在排水管路上，工藝非常簡單，通用性強(qiáng)，造價(jià)低，止回球的表面只有一層橡膠包裹，落下的時(shí)候會與球墨鑄鐵殼體碰撞發(fā)出很大的噪音。安裝止回閥是為了保證水泵內(nèi)部水流的流向，從而保障水泵的正常工作。</p><div
