style="font-size:16px;">閥門的型號(hào)是用來(lái)表示閥類、驅(qū)動(dòng)及連接形式、密封圈材料和公稱壓力等要素的。由于閥門種類繁雜，為了制造和使用方便，國(guó)家對(duì)閥門產(chǎn)品型號(hào)的編制方法做了統(tǒng)一規(guī)定。閥門產(chǎn)品的型號(hào)是由七個(gè)單元組成，用來(lái)表明閥門類別、驅(qū)動(dòng)種類、連接和結(jié)構(gòu)形式、密封面或襯里材料、公稱壓力及閥體材料。閘閥和蝶閥在管道使用中都是起開(kāi)關(guān)，調(diào)節(jié)流量的作用。當(dāng)然在蝶閥和閘閥的選配過(guò)程中還是有方法的。在供水管網(wǎng)中為了降低管道覆土深度，一般口徑較大管道選配蝶閥，對(duì)覆土深度影響不大的，力求選配閘閥，但是同樣規(guī)格的閘閥價(jià)格又比蝶閥的價(jià)格高。至于口徑的分界線應(yīng)各地按具體情況考慮。從近十年使用情況而言，蝶閥出現(xiàn)的故障比閘閥高，因此在條件許可的情況下，擴(kuò)大閘閥的使用范圍是值得關(guān)注的。</span> </p><p> <span style="font-size:16px;">蝶閥為隔離和調(diào)節(jié)流體流量提供了一種有效的截止方法。傳統(tǒng)閘閥技術(shù)的繼任者-笨重，難以安裝并且不能提供防止排放和生產(chǎn)效率低下所需的嚴(yán)密關(guān)斷-1950年開(kāi)發(fā)的蝶閥是一種較小，較輕的替代品，可以有效解決泄漏問(wèn)題。場(chǎng)上的系列蝶閥是彈性座式蝶閥，用于在低壓，低溫環(huán)境（例如公用事業(yè)應(yīng)用）中代替閘閥。這些彈性座閥蝶閥襯有彈性體，并具有同心圓盤設(shè)計(jì)，這意味著圓盤和軸位于閥體和管道的中心。閥板從完全關(guān)閉到完全打開(kāi)旋轉(zhuǎn)90度，可以安裝手動(dòng)或電動(dòng)執(zhí)行器。旋轉(zhuǎn)執(zhí)行器會(huì)移動(dòng)圓盤以限制或允許流經(jīng)管道的流量。這種設(shè)計(jì)允許用戶調(diào)節(jié)通過(guò)其系統(tǒng)的流量。隨著行業(yè)對(duì)蝶閥技術(shù)的日益熟悉，**終用戶意識(shí)到其更緊湊，更輕的設(shè)計(jì)可用于應(yīng)對(duì)廣泛應(yīng)用中的排放和安全挑戰(zhàn)。隨著內(nèi)襯彈性體的蝶閥的發(fā)展，**終用戶可以在溫度更高和腐蝕性更高的應(yīng)用中使用它們，例如輕度腐蝕，食品服務(wù)和熱風(fēng)。這種發(fā)展的一個(gè)例子是艾默生的帶TFE閥座的KeystoneFigure990/920，在食</span><span
