1、蝶閥技術(shù)說明1、用途蝶閥廣泛用于冶金、石油化工、電力、給排水、環(huán)保、建筑、礦山等行業(yè)中，用于管道的連通、截斷、調(diào)節(jié)流量。產(chǎn)品具有足夠剛度和強度及可靠性、性能穩(wěn)定可靠，保證系統(tǒng)具有良好的動態(tài)品質(zhì)，長期穩(wěn)定連續(xù)工作的能力。2、主要技術(shù)參數(shù)公稱壓力：1.OMPa1.6MPa2.5MPa適用溫度：軟密封（X）：-20C80C；硬密封（H）：-20C250c泄漏量：符合GB/T13927-2008適用介質(zhì)：水、污水、油品等3、4、特點1）偏心設(shè)計主要零部件材料零件名稱材料閥體鑄鋼WCB球墨鑄鐵QT450-10蝶板鑄鋼WCB球墨鑄鐵QT450-10閥桿不銹鋼2013密封面X：丁醺橡膠；H:不銹鋼填料石墨閥

2、桿與軸中心線與密封面的偏心可以使密封圈不受閥桿影響而與閥座密封面形成良好的接觸面，閥桿中心線與蝶板軸心的偏心，可防止在接近全開范圍內(nèi)密封面20%勺之間的一直接觸的，有效地減輕了開啟力矩。用非對稱橢圓弧密封面代替?zhèn)鹘y(tǒng)球形密封面，大大降低密封面摩擦力矩，減少密封面的磨損，讓蝶閥啟閉省力。2）重量輕、便于安裝、操作方便、省力、維修簡單、可更換填料；3）米用短系列結(jié)構(gòu)，閥門重量輕，便于安裝。4）密封可靠，密封圈耐溫、抗老化、耐磨性能好；更換維修方便。5）雙向密封，安裝無方向要求。6）閥門蝸輪機構(gòu)設(shè)有開度指示盤，可就地觀察閥門開關(guān)位置。5、使用標準如下整體鋼制管法蘭GB/T9113法蘭連接金屬閥門結(jié)構(gòu)長
