style="font-size:16px;">閘閥和蝶閥在管道使用中都是起開關(guān)，調(diào)節(jié)流量的作用。當然在蝶閥和閘閥的選配過程中還是有方法的。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)格的閘閥價格又比蝶閥的價格高。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，擴大閘閥的使用范圍是值得關(guān)注的。關(guān)于閘閥近年來，國內(nèi)不少閥門制造廠家，研制、仿制軟密封閘閥，這種閘閥比傳統(tǒng)的楔式或平行雙閘板式閘閥有如下特點：軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機械加工，不使用密封銅環(huán)，節(jié)約有色金屬。軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機械加工，不使用密封銅環(huán)，節(jié)約有色金屬。軟密封閘閥底部無凹坑，不積存渣物，閘閥啟閉的故障率低。軟密封襯膠閥板尺寸統(tǒng)一，互換性強。</span>

style="font-size:16px;">市場上使用的一般閘閥普遍存在著漏水或生銹現(xiàn)象，本企業(yè)引進歐洲高科技橡膠及閥門制造技術(shù)所生產(chǎn)的彈性座封閘閥，克服了一般閘閥密封不良，生銹等缺陷，彈性座封閘閥利用彈性閘板產(chǎn)生微量彈性變形的補償作用達到良好的密封效果，該閥具有開關(guān)輕巧、密封可靠、彈性記憶佳及使用壽命等優(yōu)點。可用于自來水、污水、建筑、石油、化工、食品、輕紡、電力、船舶、冶金、能源系統(tǒng)等體管線上作為調(diào)節(jié)和截流裝置使用。重量輕：本體采用高級球黑鑄鐵（球墨鑄鐵）制成，重量較傳統(tǒng)閘閥重量減輕約20%~30%，安裝維修方便。平底式閘座：傳統(tǒng)的閘閥往往在通水洗管后即因外物諸如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內(nèi)，容易造成無法關(guān)閉緊密而形成漏水現(xiàn)象，彈性座封閘閥底部采用與水管相同的平底</span><span
