為了減少球閥的操作扭矩和增加密封的可靠程度,又出現(xiàn)了油封球閥,既在密封面間壓注特制的潤滑油,以形成一層油膜,即增強了密封性,又減少了操作扭矩,更適用高壓大口徑的球閥。調(diào)節(jié)球閥由于球芯帶有 V 型結(jié)構(gòu),對閥座具有剪切作用。因此適用于造紙、化工、冶金等工業(yè)企業(yè)中含有纖維或微小固體顆粒的懸濁液介質(zhì)中對有關(guān)工藝參數(shù)的控制,特別適用于制漿、造紙生產(chǎn)過程中的紙漿、白水、黑液、白液等懸浮顆粒的流體及濃、濁漿狀流體介質(zhì)的自動調(diào)節(jié)。
這種V型球閥屬于固定球閥,也是單閥座密封球閥,調(diào)節(jié)性能是球閥中好的,流量特性是等百分比的,可調(diào)比達100:1。它的V型切口與金屬閥座之間具有剪切作用,特別適合含纖維、微小固體顆粒、料漿等介質(zhì)三通球閥三通球閥有T型和L型。T型能使三條正交的管道相互聯(lián)通和切斷第三條通道,起分流、合流作用。L型只能連接相互正交的兩條管道,不能同時保持第三條管道的相互連通,只起分配作用。
閥門(Valve)是控制流動的流體介質(zhì)的流量、流向、壓力、溫度等的機械裝置,閥門是管道系統(tǒng)中基本的部件。閥門管件在技術(shù)上與泵一樣,常常作為一個單獨的類別進行討論。閥門可用手動或者手輪,手柄或踏板操作,也可以通過控制來改變流體介質(zhì)的壓力,溫度和流量變化。閥門可以對這些變化進行連續(xù)或重復(fù)的操作,比如在熱水系統(tǒng)或蒸汽鍋爐安裝的安全閥。在更復(fù)雜的控制系統(tǒng)根據(jù)外部輸入(即調(diào)節(jié)流經(jīng)管道不斷變化的設(shè)置點)的需要采用自動控制閥門。自動控制閥門不需人工操作根據(jù)其輸入和設(shè)置,使閥門準(zhǔn)確控制流體介質(zhì)的各項要求。閥門根據(jù)材質(zhì)還分為鑄鐵閥門,鑄鋼閥門,不銹鋼閥門,鉻鉬鋼閥門,鉻鉬釩鋼閥門,雙相鋼閥門,塑料閥門,非標(biāo)訂制等閥門材質(zhì)。
閥門的零部件在組裝前必須經(jīng)過以下過程處理:
1、根據(jù)加工要求,部分零部件需要做拋光處理,表面不能有加工毛刺等;
2、所有零部件進行脫脂處理;
3、脫脂完成后進行酸洗鈍化,清洗劑不含磷;
4、酸洗純化后用純凈水沖洗干凈,不能有藥劑殘留,碳鋼部件省去此步驟;
5、逐個零部件用無紡布進行擦干,不能有線毛等留存部件表面,或者用潔凈的氮氣進行吹干;
6、用無紡布或者精密濾紙沾分析純酒精對逐個零部件進行擦拭,直至沒有臟色。
閥門是工業(yè)上一種重要的流體控制設(shè)備,涉及到部門,是發(fā)展重要基礎(chǔ)設(shè)備。經(jīng)過幾十年的發(fā)展,閥門產(chǎn)品已經(jīng)形成十幾大類,,但大多是小規(guī)模、低層次閥門的企業(yè),產(chǎn)品也以中低端為主。單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥,它與單向閥相同,用以防止油液反向流動。
但在液壓回路中需要油流反向流動時又可利用控制油壓,打開單向閥,使油流在兩個方向都可流動。液控單向閥采用錐形閥芯,因此密封性能好。在要求封閉油路時,可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無背壓的油路中可用內(nèi)泄式;否則需用外泄式,以降低控制油壓力。單向閥是氣流只能一個方向流動而不能反向流動的方向控制閥。其工作原理與液壓單向閥一樣。壓縮空氣從P口進入,克服彈簧力和摩擦力使單向閥閥口開啟,壓縮空氣從P流至A;當(dāng)P口無時,在彈簧力和A口(腔)余氣力作用下;閥口處于關(guān)閉狀態(tài),使從A至P氣流不通。先導(dǎo)型溢流閥的導(dǎo)閥部分是一個易振部位如圖3所示。在高壓情況下溢流時,導(dǎo)閥的軸向開口很小,僅0.003~0.006厘米。過流面積很小,流速很高,可達200米/秒,易引起壓力分布不均勻,使錐閥徑向力不平衡而產(chǎn)生振動。另外錐閥和錐閥座加工時產(chǎn)生的橢圓度、導(dǎo)閥口的臟物粘住及調(diào)壓彈簧變形等,也會引起錐閥的振動。所以一般認(rèn)為導(dǎo)閥是發(fā)生噪聲的振源部位。由于有彈性元件(彈簧)和運動質(zhì)量(錐閥)的存在,構(gòu)成了一個產(chǎn)生振蕩的條件,而導(dǎo)閥前腔又起了一個共振腔的作用,所以錐閥發(fā)生振動后易引起整個閥的共振而發(fā)出噪聲,發(fā)生噪聲時一般多伴隨有劇烈的壓力跳動。
