美國DFT單向閥
美(mei)國DFT公(gong)司已經有超過65年的(de)歷史，專注于(yu)單向(xiang)閥的(de)設(she)計和制造，DFT單向(xiang)閥以防止和**
管道(dao)系統(tong)的水(shui)錘現(xian)象而聞名。美(mei)國DFT*初(chu)設(she)計的基本型單(dan)向閥是為了滿足一個客(ke)戶的小型金屬密封
單向(xiang)閥要(yao)求，隨著(zhu)幾十(shi)年的發展，現在(zai)已形(xing)成(cheng)一個全系列產品，共十(shi)大系列ALC®，DLC®，
DSV®，Excalibur®，FBC®,GLC®,GPV®,PDC®,SCV®和WLC®,每一個(ge)系列都對應一種特殊的用途(tu)。
美國(guo)DFT傳統單(dan)向(xiang)閥(fa)(fa)（旋啟式(shi)單(dan)向(xiang)閥(fa)(fa)）一般依靠閥(fa)(fa)盤自重(zhong)或介(jie)質反(fan)向(xiang)作用力(li)關閉閥(fa)(fa)門。如事故(gu)停泵后(hou)介(jie)質開
始倒(dao)流(liu)(liu)，在倒(dao)泄介質的作用下，單向(xiang)(xiang)閥(fa)迅速(su)關閉，由(you)于閥(fa)座摩阻及介質慣性的影響，美國(guo)DFT單向(xiang)(xiang)閥(fa)關閉通常滯(zhi)后于開(kai)始倒(dao)流(liu)(liu)的時(shi)間(jian)，即在倒(dao)流(liu)(liu)量(liang)增至一(yi)定值，甚至在*大(da)倒(dao)流(liu)(liu)量(liang)的瞬間(jian)迅速(su)關閉，則能在單向(xiang)(xiang)閥(fa)處(chu)產生非常大(da)的壓(ya)力。壓(ya)力峰值高，而(er)且持(chi)續時(shi)間(jian)較(jiao)長，*易產生水錘 。
美國(guo)DFT緩沖式(shi)(shi)單向閥(fa)(fa)：采用彈簧復位(wei)，緩沖式(shi)(shi)設計，可(ke)以**或*大(da)限度減小(xiao)水錘效(xiao)應。閥(fa)(fa)門有優化的關(guan)(guan)閉(bi)(bi)特性，如在突然(ran)停泵時(shi)可(ke)迅(xun)速關(guan)(guan)閉(bi)(bi)，阻止(zhi)(zhi)介質倒流保護水泵不致(zhi)發生反轉(zhuan)，達到保護水泵的目(mu)的；且可(ke)在關(guan)(guan)閉(bi)(bi)的*后階段實現(xian)緩閉(bi)(bi)，減少突然(ran)關(guan)(guan)閉(bi)(bi)造成管路(lu)中的水錘，達到保護管路(lu)的目(mu)的。壓力(li)峰值小(xiao)，持續時(shi)間短，避免了如其(qi)它(ta)形(xing)式(shi)(shi)單向閥(fa)(fa)閥(fa)(fa)盤(pan)撞擊閥(fa)(fa)座(zuo)產生的水錘現(xian)象，降(jiang)低系統(tong)噪(zao)音，并防(fang)止(zhi)(zhi)管路(lu)系統(tong)損壞。
