style="font-size:16px;">彈性座封閘閥特點(diǎn)1.長(zhǎng)期以來(lái)市場(chǎng)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(jìn)歐洲高科技橡膠及閥門(mén)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(bǔ)償作用達(dá)到良好的密封效果，該閥具有開(kāi)關(guān)輕巧、密封可靠、彈性記憶佳及使用壽命等優(yōu)點(diǎn)。2.雙閘板閘閥應(yīng)垂直安裝(即閥桿處于垂直位置,手輪在頂部)。3.帶有旁通閥的閘閥在開(kāi)啟前應(yīng)先打開(kāi)旁通閥(以平衡進(jìn)出口的壓差及減小開(kāi)啟力)。4.帶傳動(dòng)機(jī)構(gòu)的閘閥，按產(chǎn)品使用說(shuō)明書(shū)的規(guī)定安裝。5.如果閥門(mén)經(jīng)常開(kāi)關(guān)使用,每月至少潤(rùn)滑一次。針對(duì)一般的軟密封閘閥密封性不理想這點(diǎn)，聯(lián)塑法蘭式彈性座封閘閥通過(guò)技術(shù)改良后，更好地解決了閘閥的密封性，讓暗桿軟密封閘閥被運(yùn)用在、冶金、</span><span

style="font-size:16px;">直埋式彈性座封閘閥用途傳統(tǒng)閥門(mén)安裝方式是將閥門(mén)安裝在閥門(mén)井內(nèi)，但是閥門(mén)井造價(jià)高、影響美觀、下井操作不方便，井蓋常造成丟失或人為損壞，在人行橫道及汽車(chē)行駛路面等場(chǎng)合易造成危險(xiǎn)，“馬路驚魂”的現(xiàn)象層出不窮。由此，為解決這些問(wèn)題，結(jié)合軟密封閘閥結(jié)構(gòu)穩(wěn)定、耐用等特點(diǎn)，一種新概念的“直埋式”彈性座封閘閥應(yīng)運(yùn)而生。直埋式彈性座封閘閥由閥門(mén)、直脈裝置(包括伸縮桿、伸縮護(hù)套、直埋盒)等部分組成。其閥門(mén)部分除了具有軟密封閘閥的所有特點(diǎn)之外，還具備**技術(shù)的環(huán)氧樹(shù)脂噴涂防腐技術(shù)，閥體不會(huì)生銹，確保三十年免維護(hù)。由于彈性座封閘閥壽命長(zhǎng)，性能穩(wěn)定，我們對(duì)彈性座封閘閥在原來(lái)的基礎(chǔ)上添加了一個(gè)伸縮桿、伸縮護(hù)套，并配以直埋盒，由此形成直埋式彈性座封閘閥。</span> </p><p> <span style="font-size:16px;">彈性座封閘閥的內(nèi)外防腐(包括變速傳動(dòng)箱體)內(nèi)外，首先應(yīng)拋丸清砂除銹，力求靜電噴涂粉狀無(wú)毒環(huán)氧樹(shù)脂，厚度達(dá)。特大型閥門(mén)靜電噴涂無(wú)毒環(huán)氧樹(shù)脂有困難時(shí)，亦應(yīng)刷涂、噴涂相似的無(wú)毒環(huán)氧漆。一方面浸泡在水中不會(huì)銹蝕，在兩種金屬之間不產(chǎn)生電化學(xué)腐蝕；二方面表面光滑使過(guò)水阻力減少。，應(yīng)有相應(yīng)**機(jī)關(guān)的檢測(cè)報(bào)告?；瘜W(xué)物理性能亦應(yīng)符合相關(guān)要求。彈性座封閘閥包裝運(yùn)輸。、小口徑閥門(mén)應(yīng)以草繩捆扎，并以集裝箱方式運(yùn)輸為宜。，以免運(yùn)輸過(guò)程中碰損。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板；也可以做成能產(chǎn)生微量</span><span

style="font-size:16px;">彈性性座封閘閥由于采用噴涂工藝，環(huán)氧樹(shù)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(kāi)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(guò)多，就是大口徑閥門(mén)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(pán)的閥門(mén)不適用于地下管網(wǎng)。</span>
