style="text-indent:25px">減壓閥的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。減壓閥的基本作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。近年來又出現(xiàn)一些新型減壓閥，如定比式減壓閥。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無振動(dòng)；閥體內(nèi)無彈簧，對(duì)夾式自動(dòng)蝶閥批發(fā)公司，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動(dòng)壓（水流動(dòng)時(shí)）又減靜壓（流量為0時(shí)）；特別是在減壓的同時(shí)不影響水流量。減壓閥通常有DN50～DN100等多種規(guī)格，閥前，對(duì)夾式自動(dòng)蝶閥批發(fā)公司、后的工作壓力分別為＜1MPa和0．1～0．5MPa，對(duì)夾式自動(dòng)蝶閥批發(fā)公司，調(diào)壓范圍誤差為±5％～10％。隨著防化學(xué)腐蝕的合成橡膠在蝶閥上的應(yīng)用，蝶閥的性能得以提高。對(duì)夾式自動(dòng)蝶閥批發(fā)公司</p><div

style="text-indent:25px">蝶閥的優(yōu)點(diǎn)：1、啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。2、結(jié)構(gòu)簡單，外形尺寸小，結(jié)構(gòu)長度短，體積小，重量輕，適用于大口徑的閥門。3、可以運(yùn)送泥漿，在管道口積存液體少。4、低壓下，可以實(shí)現(xiàn)良好的密封。5、調(diào)節(jié)性能好。6、全開時(shí)閥座通道有效流通面積較大，流體阻力較小。7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。9、安裝方便。10、操作靈活省力，可選擇手動(dòng)、電動(dòng)、氣動(dòng)、液壓方式。</p><p style="text-indent:25px">減壓閥的防護(hù)設(shè)施：減壓閥安裝設(shè)施一般有三種形式。減壓閥前后裝有壓力表，方便觀察閥前和閥后的壓力。閥后還有裝有全封閉式的穩(wěn)定閥，以防減壓閥失效后，閥后壓力超過正常的壓力時(shí)起跳，包含閥后系統(tǒng)。泄水管裝在閥前切斷閥前面，主要是排水河沖洗作用，有的采用疏水閥。旁通管主要作用是當(dāng)減壓閥出現(xiàn)故障后，關(guān)閉減壓閥前后的切斷閥，打開旁通閥，用手工調(diào)節(jié)流量，起到臨時(shí)流通作用，以便檢修減壓閥或更換減壓閥。以上就是減壓閥的一些防護(hù)設(shè)施說明。閥體內(nèi)或閥后噴入冷卻水，將介質(zhì)的溫度降低，這種閥門稱為減壓減溫閥。</p><div

style="text-indent:25px">減壓閥是通過調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。按結(jié)構(gòu)形式可分為薄膜式、彈簧薄膜式、活塞式、杠桿式和波紋管式；按閥座數(shù)目可分為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式。蝶閥初度運(yùn)轉(zhuǎn)時(shí)，要供認(rèn)電動(dòng)機(jī)滾動(dòng)的方向是不是精確。對(duì)夾式自動(dòng)蝶閥批發(fā)公司</p><p
