20202-2000 《脫脂工程施工及驗收規(guī)范》，裝配前每個零部件均用干凈的精密濾紙進(jìn)行擦拭，選擇部件死角，濾紙不變顏色為合格。蘇州閥門電裝生產(chǎn)廠家檢查閥桿和閥桿螺母的梯形螺紋磨損情況、填料是否過時失效等，并進(jìn)行必要的更換。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">電力驅(qū)動的閥門：電力驅(qū)動閥門是常用的驅(qū)動方式的閥門，通常稱這種驅(qū)動裝置形式的驅(qū)動裝置為閥門電動裝置，閥門電動裝置的特點如下：1）啟閉迅速，可以較大縮短啟閉閥門所需的時間；2）可以較大減輕操作人員的勞動強度，特別適用于高壓、大口徑閥門；3）適用于安裝在不能手動操作或難于接近的位置，易于實現(xiàn)遠(yuǎn)距離操縱，而且安裝高度以不受限制；4）有利于整個系統(tǒng)的自動化；5）電源比氣源和液源容易獲得，其電線的敷設(shè)和維護也比壓縮空氣和液壓管線簡單得多。閥門電動裝置的缺點是構(gòu)造復(fù)雜，在潮濕的地方使用更為困難，用于易爆介質(zhì)時，需要采用隔爆措施。</p><p style="text-indent:25px">安裝閥門的注意事項：1.冬期施工在負(fù)溫度下進(jìn)行水壓試驗。后果：由于水壓試驗時管內(nèi)很快結(jié)冰，使管凍壞。措施：盡量在冬施前進(jìn)行水壓試驗，并且試壓后要將水吹凈，特別是閥門內(nèi)的水必須除去于凈，否則閥門將會凍裂。工程必須在冬季進(jìn)行水壓試驗時，要保持室內(nèi)正溫度下進(jìn)行，試壓后要將水吹凈。在不能進(jìn)行水壓試驗時，可用壓縮空氣進(jìn)行試驗。2.管道系統(tǒng)竣工前沖洗不認(rèn)真，流量和速度達(dá)不到管道沖洗要求。甚至以水壓強度試驗泄水代替沖洗。后果：水質(zhì)達(dá)不到管道系統(tǒng)運行要求，往往還會造成管道截面減少或堵塞。措施：用系統(tǒng)內(nèi)較大設(shè)汁流量或不應(yīng)小于3m／s的水流速度進(jìn)行沖洗。應(yīng)以排出口水色、透明度與入口水的水色、透明度目測一致為合格。酸洗純化后用純凈水沖洗干凈，不能有藥劑殘留，碳鋼部件省去此步驟。</p><div

常溫閥：用于介質(zhì)工作溫度－40℃≤t≤120℃的閥門。(4) 中溫閥：用于介質(zhì)工作溫度120℃(5) 高溫閥：用于介質(zhì)工作溫度t>450℃的閥門。按驅(qū)動方式分類：(1) 自動閥是指不需要外力驅(qū)動，而是依靠介質(zhì)自身的能量來使閥門動作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動調(diào)節(jié)閥等。(2) 動力驅(qū)動閥：動力驅(qū)動閥可以利用各種動力源進(jìn)行驅(qū)動。冬期施工在負(fù)溫度下進(jìn)行水壓試驗。閥門訂購</p><p style="text-indent:25px">分流閥類包括各種分配閥和疏水閥等，其作用是分配、分離或混合管路中的介質(zhì)。蘇州閥門電裝生產(chǎn)廠家</p><p
