style="text-indent:25px">安裝閥門(mén)的注意事項(xiàng)：1.冬期施工在負(fù)溫度下進(jìn)行水壓試驗(yàn)。后果：由于水壓試驗(yàn)時(shí)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(yàn)，并且試壓后要將水吹凈，特別是閥門(mén)內(nèi)的水必須除去于凈，否則閥門(mén)將會(huì)凍裂。工程必須在冬季進(jìn)行水壓試驗(yàn)時(shí)，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(yàn)時(shí)，可用壓縮空氣進(jìn)行試驗(yàn)。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(qiáng)度試驗(yàn)泄水代替沖洗。后果：水質(zhì)達(dá)不到管道系統(tǒng)運(yùn)行要求，往往還會(huì)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(cè)一致為合格。</p><p style="text-indent:25px">隔膜閥工作原理：隔膜閥啟閉件是一塊用軟質(zhì)材料制成的隔膜，它將閥體內(nèi)腔與閥蓋內(nèi)腔隔開(kāi)。隔膜閥實(shí)際上不過(guò)是“鉗夾”的閥，一個(gè)彈性的，可擾的膜片，用螺椿連接在壓縮件上，壓縮件是由閥桿所操作而上下移動(dòng)，當(dāng)壓縮件上升，膜片就高舉，而造成通路，當(dāng)壓縮件下降，膜片就壓在閥體堰上（假使為堰式閥）或壓在輪廓的底部（假使為直通式）。隔膜閥作用隔膜閥適用于開(kāi)關(guān)及節(jié)流之用，隔膜閥的結(jié)構(gòu)簡(jiǎn)單、流體阻力小、流通能力較同規(guī)格的其他類型閥大；無(wú)泄漏，能用于高粘度及有懸浮顆粒介質(zhì)的調(diào)節(jié)。隔膜把介質(zhì)與閥桿上腔隔離，所以沒(méi)有填料介質(zhì)也不會(huì)外漏。但是，由于隔膜和襯里材料的限制，耐壓性、耐溫性較差，一般只適用于1.6MPa公稱壓力和150℃以下。試壓方法隔膜閥強(qiáng)度試驗(yàn)從任一端引入介質(zhì)，開(kāi)啟閥瓣，另一端封閉，試驗(yàn)壓力升至規(guī)定值后，看閥體和閥蓋無(wú)滲漏為合格。然后降壓至密封性試驗(yàn)壓力，關(guān)閉閥瓣，打開(kāi)另一端進(jìn)行檢查，無(wú)滲漏為合格。運(yùn)行中的閥門(mén)，避免對(duì)其敲打，或者支撐重物等。</p><div
