D73H-150LB美標(biāo)蝶閥，驅(qū)動(dòng)方式可選用手動(dòng)、蝸輪、氣動(dòng)、電動(dòng)，連接方式可選用法蘭、對(duì)夾，結(jié)構(gòu)形式可選用中線式、偏心式，密封結(jié)構(gòu)可選用軟密封、硬密封，壓力范圍PN0.1-10Mpa，公稱通徑為DN40-1200mm，材質(zhì)可選用鑄鐵、鑄鋼、不銹鋼。

D73H-150LB美標(biāo)蝶閥用途和特點(diǎn)：

美標(biāo)蝶閥廣泛適用于低壓、中壓、高壓、鋼鐵治金、石油、化工、電力等工業(yè)管道上作截?cái)嗷蛘{(diào)節(jié)介質(zhì)流量用。該帆門采用三維偏心斜錐形閥座密封，蝶板密封采用新型金屬片與彈性材料層疊而成，嵌裝在蝶板上與閥座吻合。利用蝶板擺動(dòng)壓緊密封，所以密封面摩擦阻力小，關(guān)閉時(shí)具有越關(guān)越緊功能，這樣密封性可靠，開(kāi)啟確保密封面完全脫離接觸，保證了密封面不受損傷。該蝶閥結(jié)構(gòu)特點(diǎn)排除了其他類型蝶閥開(kāi)過(guò)位而不能密封的缺點(diǎn)，且在高曙下能正常使用，克服了其它類型閥門在高溫使用時(shí)因熱膨脹而容易泄漏的缺點(diǎn)。該蝶閥耕具使用介質(zhì)要求，選用不同密封面材料，以保證密封面耐磨損、耐腐蝕、使用壽命長(zhǎng)。
