氣動襯氟蝶(dié)閥,屬于(yú)對夾/法蘭(lán)式襯氟蝶閥系列;它由氣(qì)動執 行機構和襯氟蝶閥組成,閥體部分可與氣動、電動執行機構(gòu)選配 組合,組成各種不同類型的蝶閥品種規格。該産品按其(qí)襯裡材質 分為全襯氟(fú)蝶閥和半襯氟蝶(dié)閥。全襯氟蝶閥由于襯氟蝶閥閥體内(nèi) 腔均有抗腐蝕的(de)氟塑料(PTFE/FEP/PFA) 制(zhì)成襯裡, 同時對蝶闆 和閥杆裡進行(háng)包襯氟塑料,并在(zài)閥基面内設有矽橡膠襯墊,用來調 節閥座(zuò)基面(miàn)預緊,以達到(dào)與蝶(dié)闆密封性能。閥體采用分離式,閥軸 兩端的(de)密封(fēng)由蝶闆與閥座之間的旋轉基面靠氟橡膠圈來控制,從 而使閥軸不與(yǔ)腔内介質接觸(chù),保證了密封無洩漏。
Pneumatic actuator control butterfly valve is YFM patent product, which belong to D671waferandD 641 flange type lined butterfly valve series, consist of pneumatic actuator and lined butterfly valve. These valves are divided into fully lined butterfly valve and half lined butterfly valve according to different lining ways.Fully lined butterfly refers to the PTFE/PFA/FEP seat and disc lined with PTFE/PFA/FEP. There is silicon pad to adjust pre-tighten for keeping the best sealing. valve body is split.The sealing of axis end is controlled by Viton which locate between disc and seat, so that the axis is out of touch medium to ensure the sealing without any leakage.
