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；同時閥體底部設(shè)計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，可減少開關(guān)時的摩擦阻力，大幅減少漏水現(xiàn)象。彈性座封閘閥操作時的啟閉方向，一律應(yīng)順時針關(guān)閉。由于管網(wǎng)中的氣動閥，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，且尺寸標準化，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>
