進口鍛鋼法蘭止回閥工作原理： 

進口鍛鋼法蘭止回閥閥瓣、閥座密封面采用鐵基合金或司太立（Stellite）鈷基硬質(zhì)合金堆焊面成耐磨、耐高溫、耐腐蝕、抗擦傷性能好使用壽命長等特點。不銹鋼銷軸與閥瓣連接采用內(nèi)裝式結(jié)構(gòu)-性能優(yōu)良-密封更可靠。產(chǎn)品廣泛應(yīng)用于石油、化工、制藥、電力行業(yè)等各種工況的管路上防介質(zhì)倒流作用。適用介質(zhì)為水、油品、蒸汽、氣體及某些腐蝕性液體介質(zhì)等。

Working principle of imported forged steel flange check valve:
The sealing surface of imported forged steel flange check valve disc and seat is made of iron-based alloy or Stellite cobalt based hard alloy. The surfacing surface is characterized by good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life. The connection between stainless steel pin and valve disc adopts built-in structure - excellent performance - more reliable sealing. Products are widely used in petroleum, chemical, pharmaceutical, electric power industry and other working conditions of the pipeline anti backflow effect. The suitable medium is water, oil, steam, gas and some corrosive liquid medium.
