style="text-indent:25px">減溫減壓裝置由兩個(gè)**作用的止回閥和泄水閥組成，能嚴(yán)格限定管道中的壓力水只能單向流動的水力控制裝置。減壓閥開啟泄壓，減壓閥又關(guān)閉。當(dāng)閥后管網(wǎng)壓力升高，超過閥前進(jìn)口壓力時(shí)，如出口位置上的止回閥密封完好無泄漏，高壓水不會倒流，隔膜左右保持原來的壓差，減壓閥關(guān)閉不泄漏。當(dāng)出口位置上的止回閥密封破壞造成滲漏，出口位置上的止回閥之前壓力升高，造成減壓閥隔膜左右壓差減小，減壓閥打開通過排水口泄壓。用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然過大，流量變化時(shí)，輸出壓力波動較大，閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點(diǎn)，可采用減溫減壓裝置。</p><p style="text-indent:25px">減溫減壓裝置注意事項(xiàng)：為了操作和維護(hù)方便，該閥一般直立安裝在水平管道上。減溫減壓裝置安裝必須嚴(yán)格按照閥體上的箭頭方向保持與流體流動方向一致。如果水質(zhì)不清潔，含有一些雜質(zhì)，必須在減溫減壓裝置的上游進(jìn)水口安裝過濾器。3為了防止閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個(gè)減溫減壓裝置。4.減溫減壓裝置在管道中起到一定的止回作用，為了防止水錘的危害，也可安裝小的膨脹水箱，防止損壞管道和閥門，過濾器必須安裝在減溫減壓裝置的進(jìn)水管前，而膨脹水箱必須安裝在減溫減壓裝置出水管后！減溫減壓裝置的制作材料屬于低摩擦，減小了金屬與金屬之間的相互摩擦。安全閥下應(yīng)設(shè)以固定支架，泄壓應(yīng)排至安全處。</p><div

style="text-indent:25px">減溫減壓裝置采用減壓閥結(jié)構(gòu)，在同一閥中進(jìn)行蒸汽減壓，縮短了整個(gè)裝置的長度，減少了占地面積，減少了工程投資。減壓閥的流量特性：線性或修正百分比特性曲線可在全沖程范圍內(nèi)精確控制，以確保二次蒸汽在額定輸出的10?100%范圍內(nèi)，以穩(wěn)定運(yùn)行設(shè)備很長一段時(shí)間。泄漏等級：IV級。溫度給水調(diào)節(jié)系統(tǒng)采用直行程高壓差控制閥，可以合理分配給水系統(tǒng)的壓差。相同口徑的高壓差動給水控制閥具有不同的流量系數(shù)Cv值可供選擇，這使得溫度調(diào)節(jié)系統(tǒng)的調(diào)節(jié)靈敏度和調(diào)節(jié)精度提高。減溫減壓裝置在管道中起到一定的止回作用。山東減溫減壓裝置公司有哪些</p><p

style="text-indent:25px">減溫減壓裝置在運(yùn)行過程中分為兩個(gè)物理過程，一個(gè)是減壓，另一個(gè)是減溫。減溫原理是壓力調(diào)節(jié)閥的原理。將水噴入高溫蒸汽中。過熱水在通過噴嘴后分散成小水滴。一段時(shí)間后，水霧蒸發(fā)，從而降低蒸汽溫度，該過程遵循熱平衡原理。減溫減壓裝置需要考慮一個(gè)蒸汽條件，減溫水條件，溫度和壓力測量，信號傳輸，截止隔離裝置，安全系統(tǒng)，管道布置和連接的內(nèi)容。因此從嚴(yán)格意義上講，我們應(yīng)該將其稱為減溫減壓系統(tǒng)。整個(gè)降溫和減壓系統(tǒng)有許多組件。從結(jié)構(gòu)上，我們可以將它分成幾個(gè)模塊來別討論。如減壓模塊，減溫模塊，減溫水控模塊，測量模塊，安全模塊，截止隔離模塊，管道傳輸模塊，連接模塊等。每個(gè)模塊負(fù)責(zé)不同的功能，針對不同的方向，參考不同的數(shù)據(jù)，共同完成蒸汽減溫和減壓工作，并輸出高質(zhì)量和穩(wěn)定的二次蒸汽。常州減溫減壓裝置一般多少錢</p></p><br
