一、進(jìn)口外螺紋焊接止回閥 品牌：美國(guó)威盾VTON 進(jìn)口外螺紋焊接止回閥是指采用鍛造不銹鋼結(jié)構(gòu)，外螺紋的連接方式，帶焊接管，可拆卸，安裝維修方便。主要用于高壓加壓的天然氣加氣系統(tǒng)，防止加壓天然氣倒流的閥門。焊接式高壓?jiǎn)蜗蜷y是靠管路中介質(zhì)本身的流動(dòng)產(chǎn)生的力而自動(dòng)開啟和關(guān)閉的，屬于一種自動(dòng)閥門。焊接式高壓?jiǎn)蜗蜷y只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。 Detachable welding high-pressure check valve is mainly used for pressurized gas filling system, pressurized gas to prevent backflow valve. Welding type high pressure check valve is generated by the pipeline flow of the medium itself force automatically turned on and off, is an automatic valve. Welding type high pressure check valve is only allowing media to flow in one direction, and stop the flow direction. 二、進(jìn)口外螺紋焊接止回閥參數(shù)Parameters 公稱壓力： PN16、PN32、PN40、PN50Mpa Nominal pressure: PN16, PN32, PN40, PN50Mpa 公稱通徑：DN3～DN50 Nominal diameter: DN3 ~ DN50 焊接管外徑Welded pipe diameter ∮10，∮12，∮14，∮16，∮18，∮20，∮22，∮25，∮28，∮30，∮32，∮40，∮42，∮50，∮57 適用介質(zhì)：加壓天然氣CNG﹑水﹑氣等 Suitable medium: CNG, water, gas etc. 適用溫度：-20℃～+120℃ -70℃～180℃等 Applicable temperature: -20℃～+120℃ -70℃～180℃ 制造材料：20#﹑1Cr18Ni9Ti﹑304﹑316﹑316L﹑12Cr1Mov等 Material: 20#, 1Cr18Ni9Ti, 304, 316, 316L, 12Cr1Mov etc. 三、進(jìn)口外螺紋焊接止回閥業(yè)績(jī)Performance 中國(guó)石油天然氣集團(tuán)公司，深圳空港油料加氣站，北京市燃?xì)饧瘓F(tuán)有限責(zé)任公司，重慶燃?xì)饧瘓F(tuán)，河南藍(lán)天燃?xì)夤煞萦邢薰�，新疆燃�(xì)?集團(tuán))有限公司，成都城市燃?xì)庥邢挢?zé)任公司，太原煤炭氣化(集團(tuán))有限責(zé)任公司，新疆廣匯實(shí)業(yè)股份有限公司等。 China Petroleum Natural Gas Group Company, Shenzhen airport oil filling station, Beijing gas Refco Group Ltd, Chongqing gas group, Henan gas Limited by Share Ltd, Xinjiang gas (Group) Co.
