進(jìn)口高溫對(duì)焊閘閥(德國OLES奧萊斯閥門)
【進(jìn)口高溫對(duì)焊閘閥】詳細(xì)說明：
高溫高壓焊接閘閥啟閉件是剛性實(shí)心閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，可作全開或全關(guān)用，閥體采用整體鍛造，非常適合高溫高壓工況用。閘閥流體阻力小，密封面受介質(zhì)的沖刷和侵蝕小，開閉較省力，介質(zhì)流向不受限制，不擾流、不降低壓力，形體簡單，結(jié)構(gòu)長度短，制造工藝性好，適用范圍廣。
The opening and closing parts of high temperature and high pressure welding gate valve are rigid solid gates. The moving direction of gate plate is perpendicular to the direction of fluid. It can be used for full opening or full closing. The valve body is forged entirely, which is very suitable for high temperature and high pressure operation. The gate valve has small fluid resistance, small erosion and erosion of the sealing surface by the medium, easy opening and closing, unlimited flow direction of the medium, no disturbance, no pressure reduction, simple shape, short structure length, good manufacturing technology and wide application range.
【進(jìn)口高溫對(duì)焊閘閥】工作原理：
高溫高壓焊接閘閥中腔采用壓力自緊式密封結(jié)構(gòu)，內(nèi)腔壓力越高密封性能越好。支管兩端為焊接結(jié)構(gòu)，適應(yīng)不同的接管要求。閘板和閥座的密封面采用司太立(stellite)鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，耐腐蝕，抗擦傷性能好。閥桿經(jīng)調(diào)質(zhì)和表面氮化處理，有良好的抗腐蝕性和抗擦傷性。啟閉件的結(jié)構(gòu)可根據(jù)用戶要求設(shè)計(jì)成單板、雙板、平行雙板等不同形式。焊接連接的閘閥適用于公稱壓力42.0Mpa工作溫度≤600℃的石油、化工、火力電站等各種工況的管路上，切斷或接通介質(zhì)。
