本蝶閥采用的是三維偏心原理設(shè)計，是在原有的雙偏心基礎(chǔ)上增加了一個獨(dú)特的偏心，不僅利用了原有的凸輪效應(yīng)，而且完全消除了90度旋轉(zhuǎn)中閥板與密封圈之間的全部磨擦。
通過優(yōu)化了蝶板密封面與閥座密封圈之間接觸角的特性，閥門接觸角大于鎖定錐角范圍。從幾何形狀看，排除了蝶板卡死的可能性，從而確保閥門開關(guān)所需扭矩。蝶板密封面可以鑲不銹鋼密封圈或在蝶板上直接堆焊不銹鋼或硬質(zhì)合金，可確保閥門在各種用途包括高溫和不潔工況下耐用。主要零件材料：零件名稱材料閥體鑄鐵、不銹鋼、鉻鉬鋼、合金鋼蝶板鑄鋼、合金鋼、不銹鋼、鉻鉬鋼密封圈不銹鋼與耐高溫石棉板組合成多層次閥桿2Cr13、1Cr13不銹鋼、鉻鉬鋼填料柔性石墨D3（6、9）43H-6～10（C、P、R、V）系列連接尺寸：公稱通徑DN外形尺寸連接尺寸LHD343HD643HD943HPN0.6MPaPN1.0MPa短長H1A1B1H2A2B2H3A3B3DD1z-dDD1z-d50108150112350180200605245725302502551401104-141651254-1865112170115370180200625245725502502551601304-141851454-1880114180120380180200645245725652502551901504-182001608-18100127190138420180200675355926002502552101704-182201808-18125140200164460180200715355926402502552402008-182502108-18150140210175555270280800355927053003152652258-182852408-2220015223020860527028085025017077530031532028012-183402958-2225016525024368027028092525017094530031537533512-2239533012-223001782702838003804201035450220107030031544039512-2244540012-223501902903108353804201070450220114030031549044516-2250546016-224002163103409154504701190450280121030031554049516-2256551516-264502223303809604504701250650280133557571459555016-2261556520-2650022935041010204804901295650280141557571464560020-2267062020-2660026739047012256406601455850380160565681075570520-2678072520-3070029243055013556406601585850380184465681086081024-2689584024-30800318470640147064066017001250380204065681097592024-30101595024-3390033051071015458509001865125038022557858631075102024-301115105028-33100041055077017958509002015150058023807858631175112028-301230116028-36120047063089019658509002226150058026407858631405134032-331455138032-3914005307109202380     2886  1630156036-331675159036-42160060079010852956     3156  1820176040-331915185040-54180067087012303221     3421  2045197044-422115202044-54200076095013503485     3685  2265218048-482325223044-54
