style="font-size:16px;">彈性性座封閘閥由于采用噴涂工藝，環(huán)氧樹脂涂層表面非常光滑，極大地降低了介質(zhì)流經(jīng)通道的表面粗糙度，因此流阻小、水頭損小；同時(shí)閥體底部設(shè)計(jì)為直通型也減少了流阻和水頭損失。特殊軸密封由于閥桿采用三道O型圈密封，一道防塵圈密封設(shè)計(jì)，可減少開關(guān)時(shí)的摩擦阻力，大幅減少漏水現(xiàn)象。彈性座封閘閥操作時(shí)的啟閉方向，一律應(yīng)順時(shí)針關(guān)閉。由于管網(wǎng)中的氣動(dòng)閥，經(jīng)常是人工啟閉，啟閉轉(zhuǎn)數(shù)不宜過多，就是大口徑閥門亦應(yīng)在200－600轉(zhuǎn)內(nèi)。為了便于一個(gè)人的啟閉操作，在管道工壓狀況下，比較大啟閉力矩宜為240N-m。彈性座封閘閥啟閉操作端應(yīng)為方榫，且尺寸標(biāo)準(zhǔn)化，并面向地面，以便人們從地面上可直接操作。帶輪盤的閥門不適用于地下管網(wǎng)。</span> </p><p> <span style="font-size:16px;">閘閥的種類,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥,楔式閘板式閘閥又可分為:單閘極式、雙閘板式和彈性閘板式；平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。閘閥關(guān)閉時(shí),密封面可以只依靠介質(zhì)壓力來密封,即依靠提交介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的,即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座,以保證密封面的密封性。閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，叫升降桿閘閥（亦叫明桿閘閥）。通常在升降桿上有梯形螺紋，通過閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏Α?/span>

style="font-size:16px;">閘閥性能優(yōu)點(diǎn)閥門流體阻力小，由于閘閥閥體是直通型，介質(zhì)流動(dòng)不改變方向，因此比較其它閥門流阻要??；密封性能較截止閥要好，啟閉也較截止閥省力；適用范圍廣，除用于蒸汽、油品等介質(zhì)外，還適用于含有粒狀固體以及黏度較大的介質(zhì)，也適用于做放空閥和低真空系統(tǒng)的閥門來使用；閘閥是具有雙流向的閥門，不受介質(zhì)流向限制，因此適用于介質(zhì)可能改變流動(dòng)方向的管路，同時(shí)也便于安裝。平底式閥座，明桿閘閥和暗桿閘閥經(jīng)常用于城市污水污泥凈化系統(tǒng)重，所以與水管相同的平底閥座設(shè)計(jì)能夠減少雜物淤泥堆積，密封性能更加可靠，保證污水凈化處理的效果，客戶用得更放心。清潔維護(hù)方便，明桿閘閥相比較于暗桿閘閥的另一個(gè)優(yōu)點(diǎn)，就是清潔維護(hù)起來更方便簡潔，閘閥的閥腔內(nèi)部使用無毒環(huán)氧樹脂作為涂層，防腐蝕性和防氧化生銹效果好，提高水處理、水供應(yīng)的質(zhì)量。而且明桿閘閥還可以根據(jù)用戶的需要，加裝氣動(dòng)或電動(dòng)執(zhí)行系統(tǒng)和開關(guān)啟閉器等元件，更方便客戶操控使用明桿閘閥的開閉。</span>
