2、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)。3、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。4、閥門啟閉操作端應(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)。5、閥門啟閉程度的顯示盤①閥門啟閉程度的刻度線，應(yīng)鑄造在變速箱蓋上或轉(zhuǎn)換方向后的顯示盤的外殼上，一律面向地面，刻度線刷上熒光粉，以示醒目；②指示盤針的材質(zhì)在管理較好的情況下可用不銹鋼板，否則為刷漆的鋼板，切勿使用鋁皮制作；③指示盤針醒目，固定牢靠，一旦啟閉調(diào)節(jié)準(zhǔn)確后，應(yīng)以鉚釘鎖定。6、若閥埋設(shè)較深，操作機構(gòu)及顯示盤離地面距離≥，應(yīng)設(shè)有加長桿設(shè)施，且固定穩(wěn)牢，以便人們從地面上觀察及操作。也就是說，管網(wǎng)中的閥門啟閉操作，不宜下井作業(yè)。閥門性能檢測編輯1、閥門某一規(guī)格批量制造時，應(yīng)委托**性機構(gòu)進(jìn)行以下性能的檢測：①閥門在工壓狀況下的啟閉力矩；②在工壓狀況下，能保證閥門關(guān)閉嚴(yán)密的連續(xù)啟閉次數(shù)；③閥門在管道輸水狀況下的流阻系數(shù)的檢測。2、閥門在出廠前應(yīng)進(jìn)行以下的檢測：①閥門在開啟狀況下，閥體應(yīng)承受閥門工壓值二倍的內(nèi)壓檢測。</p><div
