style="text-indent:25px">閥門通用分類法：這種分類方法既按原理、作用又按結(jié)構(gòu)劃分，是目前國際、國內(nèi)較常用的分類方法。一般分閘閥、截止閥、節(jié)流閥、儀表閥、柱塞閥、隔膜閥、旋塞閥、球閥、蝶閥、止回閥、減壓閥安全閥、疏水閥、調(diào)節(jié)閥、底閥、過濾器、排污閥等。由于閥門的用途是普遍的，因此它起的作用也是很大的。例如：在發(fā)電廠中閥門能夠控制鍋爐和汽輪機(jī)的運(yùn)轉(zhuǎn)；在石油、化工生產(chǎn)中，閥門同樣也起著控制全部生產(chǎn)設(shè)備和工藝流程的正常運(yùn)轉(zhuǎn)。在其它部門也是這樣。盡管如此，閥門同其它產(chǎn)品比較往往被人們忽視。例如：在安裝機(jī)器設(shè)備時(shí)，人們往往把重點(diǎn)放在主要機(jī)器設(shè)備方面，如：壓縮機(jī)、高壓容器、鍋爐等；也有的選用不當(dāng)……。這些作法都會(huì)使整個(gè)生產(chǎn)效率降低或停產(chǎn)、或造成種種其它事故發(fā)生。因此，對(duì)閥門的選用、安裝、使用等都必須進(jìn)行認(rèn)真負(fù)責(zé)的工作。尤其對(duì)現(xiàn)代化工業(yè)生產(chǎn)和建設(shè)更應(yīng)如此。無錫礦用隔爆型閥門廠家填料壓蓋不允許歪斜或無預(yù)緊間隙。</p><div

style="text-indent:25px">閥門分類：按公稱壓力分類：(1) 真空閥：指工作壓力低于標(biāo)準(zhǔn)大氣壓的閥門。(2) 低壓閥：指公稱壓力PN ≤1.6Mpa 的閥門。(3) 中壓閥：指公稱壓力PN 為2.5、4.0、6.4Mpa的閥門。(4) 高壓閥：指工稱壓力PN 為10～80Mpa的閥門。(5) 超高壓閥：指公稱壓力 PN≥100Mpa的閥門。按工作溫度分類：(1) 較低溫閥：用于介質(zhì)工作溫度 t<－100℃的閥門。(2) 低溫閥：用于介質(zhì)工作溫度－100℃≤t≤－40℃的閥門。(3) 常溫閥：用于介質(zhì)工作溫度－40℃≤t≤120℃的閥門。(4) 中溫閥：用于介質(zhì)工作溫度120℃(5) 高溫閥：用于介質(zhì)工作溫度t>450℃的閥門。按驅(qū)動(dòng)方式分類：(1) 自動(dòng)閥是指不需要外力驅(qū)動(dòng)，而是依靠介質(zhì)自身的能量來使閥門動(dòng)作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動(dòng)調(diào)節(jié)閥等。(2) 動(dòng)力驅(qū)動(dòng)閥：動(dòng)力驅(qū)動(dòng)閥可以利用各種動(dòng)力源進(jìn)行驅(qū)動(dòng)。安裝應(yīng)用后的閥門，應(yīng)對(duì)其進(jìn)行定期檢修，以確保其正常工作。</p><div style="width:100%;text-align: center;"><img style="max-width:

安全閥：安全閥類的作用是防止管路或裝置中的介質(zhì)壓力超過規(guī)定數(shù)值，從而達(dá)到安全保護(hù)的目的。(4) 調(diào)節(jié)閥：調(diào)節(jié)閥類包括調(diào)節(jié)閥、節(jié)流閥和減壓閥，其作用是調(diào)節(jié)介質(zhì)的壓力、流量等參數(shù)。(5) 分流閥：分流閥類包括各種分配閥和疏水閥等，其作用是分配、分離或混合管路中的介質(zhì)。(6)排氣閥：排氣閥是管道系統(tǒng)中必不可少的輔助元件，普遍應(yīng)用于鍋爐、空調(diào)、石油天然氣、給排水管道中。往往安裝在制高點(diǎn)或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。閥門在管道輸水狀況下的流阻系數(shù)的檢測(cè)。浙江閥門銷售廠家</p><p
