RETZ瑞茨『進口蒸汽止回閥』詳細介紹●RETZ止回閥系列●RETZ蒸汽止回閥●產(chǎn)品數(shù)據(jù)
?描述--
RETZ進口蒸汽止回閥是指用在蒸汽管道上的止回閥,襯套采用耐磨性能好,摩擦系數(shù)小,啟閉件靠蒸汽或者冷凝水流動和力量自行開啟或關(guān)閉,以防止蒸汽或者冷凝水倒流的閥門,動作靈活可靠,密封性能優(yōu)良。
RETZ imported steam check valve is a check valve used on the steam pipe. The bushing has good wear resistance, small friction coefficient, the open and close parts are opened or closed by steam or condensate flow and strength to prevent the flow of steam or condensate from flow back. The action is flexible and reliable, and the sealing performance is excellent.
?工作原理--
進口蒸汽止回閥由閥體、閥蓋、閥板等組成,介質(zhì)由一端進入使閥板升高,介質(zhì)流通;當介質(zhì)壓力消失或出口壓力大于進口壓力時,閥板自行下降關(guān)閉通道,起止回作用。
?設(shè)計特點--
1.合理的結(jié)構(gòu),無需附加任何驅(qū)動附件也能自動阻止流體倒流;
材料的全面高質(zhì)量;
2.能適用于各種壓力、溫度及介質(zhì);
3.耐磨、耐高溫、耐腐蝕、抗擦傷性能好;
4.在使用過程中遇到溫差幅度變化環(huán)境下,能自然達到化學處理性能;
5.結(jié)構(gòu)緊湊,設(shè)計合理,通道流暢耐性好,流阻系數(shù)小;
?設(shè)計規(guī)范--
規(guī)格通徑:DN15~200
壓力等級:PN1.6~4.0Mpa
適用溫度:-20~540℃
連接方式:法蘭、內(nèi)螺紋、焊接
?典型應(yīng)用--
進口蒸汽止回閥廣泛應(yīng)用于石油、化工、制藥、電力、熱油、鍋爐、熱力行業(yè)等各種工況的管路上。
