管道材質(zhì)為鋼管，其波速大約為1000米/秒，因此***次水錘波返回時間則相應地大約為：秒鐘，繼而規(guī)定緩閉止回閥的關閉時間可以設為23~25秒左右：如此關閉的止回閥可以阻止大部分返回流量對水泵的沖擊，同時將流速的改變降低，從而減少壓力的升高。某個南方的閥門廠的所謂“多功能水泵控制閥”在拷貝國外閥門的基礎上更加表現(xiàn)得討巧：在水泵停止后，立即由重力作用關閉70%的閥門，當水流返回時，該流體會將剩余的30%關閉，而滯后的時間主要根據(jù)閥門的口徑而定，口徑越大則后段關閉時間就越長。但無論哪種假設與設計，都應該與具體的工況分離來看，在沒有經(jīng)過計算的系統(tǒng)當中，我們并不知道那多余的3~5秒或者30%的流量會不會有效降低壓力的升高，或者會不會造成對水泵的有害沖擊。因此同樣存在著不確定性，不加以選擇的斷然應用與根本不采用是同樣不負責任的表現(xiàn)。zPVA6~|l_PRm4:三．“國際解釋”7aU*7!U***關于止回閥的特性與所謂“好與壞”的問題。在這個問題上，遺憾的是，我們手頭并不具備太多的相關專業(yè)資料，更不要談及國內(nèi)會出現(xiàn)全威性的理論文章進行規(guī)范。*能參考的是英國人《FLUIDRANSIENTSINPIPELINESYSTEMS》（管道系統(tǒng)中的瞬變流特性）。</p><p

(一)關斷閥這類閥門是起開閉作用的。常設于冷、熱源進、出口，設備進、出口，管路分支線(包括立管)上，也可用作放水閥和放氣閥。常見的關斷閥有閘閥、截止閥、球閥和蝶閥等。閘閥可分為明桿和暗桿、單閘板與雙閘板、楔形閘板與平行閘板等。閘閥關閉嚴密性不好，大直徑閘閥開啟困難;沿水流方向閥體尺寸小，流動阻力小，閘閥公稱直徑跨度大。截止閥按介質(zhì)流向分直通式、直角式和直流式三種，有明桿和暗桿之分。截止閥的關閉嚴密性較閘閥好，閥體長，流動阻力大，比較大公稱直徑為DN200。球閥的閥芯為開孔的圓球。板動閥桿使球體開孔正對管道軸線時為全開，轉(zhuǎn)90°為全閉。球閥有一定的調(diào)節(jié)性能，關閉較嚴密。蝶閥的閥芯為圓形閥板，它可沿垂直管道軸線的立軸轉(zhuǎn)動。當閥板平面與管子軸線一致時，為全開;閘板平面與管子軸線垂直時，為全閉。蝶閥閥體長度小，流動阻力小，比閘閥和截止閥價格高形成大量的聲渦，也是整個閘閥中聲場強的位置。隨著開度變小，擴壓空間隨之減小，空腔內(nèi)的聲壓也降低。蜀山區(qū)電動閥門推薦</p><p

2)鐘形浮子式疏水閥鐘形浮子式疏水閥又稱吊桶式疏水閥(主要由調(diào)節(jié)閥、吊桶、外殼和過濾裝置等構(gòu)件組成。疏水閥內(nèi)的吊桶被倒置,開始時處于下降位置,調(diào)節(jié)閥是開啟的。當設備或管道中的冷空氣和凝結(jié)水在蒸汽壓力推動下進入疏水閥,隨即由調(diào)節(jié)閥排出。一方面,當蒸汽與沒有排出的少量空氣逐漸充滿吊桶內(nèi)部容積,同時凝結(jié)水不斷積存,吊桶因產(chǎn)生浮力而上升,使調(diào)節(jié)閥關閉,停止排出凝結(jié)水。另一方面,吊桶內(nèi)部的蒸汽和空氣有一小部分從桶頂部的小孔排出,而大部分散熱后凝成液體,從而使吊桶浮力逐漸減小而下落,使調(diào)節(jié)閥開啟,凝結(jié)水又排出。這樣周期性地工作,既可自動排出凝結(jié)水,又能阻止蒸汽外逸。(3)熱動力式疏水閥當設備或管道中的凝結(jié)水流入阻氣排水閥后,變壓室內(nèi)的蒸汽隨之冷凝而降低壓力,閥片下面的受力大于上面的受力,故將閥片頂起。因為凝結(jié)水比蒸汽的粘度大、流速低,所以閥片與閥底間不易造成負壓,同時凝結(jié)水不易通過閥片與外殼之間的間隙流入變壓室,使閥片保持開啟狀態(tài),凝結(jié)水流經(jīng)環(huán)行槽排出。當設備或管道中的蒸汽流人疏水閥后,因為蒸汽比凝結(jié)水的粘度小、流速高,所以閥片與閥座問容易造成負壓,同時部分蒸汽流入變壓室,故使閥片上面的受力大于下面的受力,使閥片迅速關閉。廬陽區(qū)塑料閥門推薦</p><p
