    D343H-16C的描述 

    閥門類型代號:“D”代表蝶閥

    驅(qū)動方式代號:“3“代表渦輪傳動

    連接方式代號:“4“代表法蘭連接

    結(jié)構(gòu)形式代號:“3“三偏心
     
    密封面材料:“H“不銹鋼鐵
             
    壓力代號:“16“代表工作溫度下的工作壓力代號
             
    閥體材料代號:“C“代表碳鋼
     
    蝶閥為偏心金屬密封結(jié)構(gòu),密封形式為金屬對金屬密封,可調(diào)換金屬密封圈對金屬密封,
    不銹鋼板與石墨復(fù)合板密封圈對金屬密封.硬密封蝶閥的驅(qū)動形式除了電動之外還有:手動,蝸輪桿傳動,氣動等
    D343H蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi),圓盤形蝶板繞著軸線旋轉(zhuǎn),
    旋轉(zhuǎn)角度為0°~90°之間,旋轉(zhuǎn)到90°時,閥門則牌全開狀態(tài)
     
    D343H的結(jié)構(gòu)特點(diǎn)
     
    1、結(jié)構(gòu)緊湊、體積小、重量輕、操作靈活、開閉扭矩小、蝶板工作平穩(wěn)、噪音小、維修方便。 
    2、設(shè)計(jì)采用三維偏心密封原理,可達(dá)到完全密封,氣壓試驗(yàn)泄漏量為零。 
    3、密封副選用不銹鋼材料,并在制造過程中采用特殊的工藝處理,具有耐高溫、高壓、耐磨、耐腐蝕、使用壽命長的特點(diǎn)。
    目前 ,D343H蝶閥作為一種用來實(shí)現(xiàn)管路系統(tǒng)通斷及流量控制的部件,已在石油、化工、冶金、水電等許多領(lǐng)域中得到極為廣泛地應(yīng)用。
    在已公知的蝶閥技術(shù)中,其密封形式多采用密封結(jié)構(gòu),密封材料為橡膠、聚四氟乙烯等。由于結(jié)構(gòu)特征的限制,
    不適應(yīng)耐高溫、高壓及耐腐蝕、抗磨損等行業(yè)。現(xiàn)有一種比較先進(jìn)的蝶閥是三偏心金屬硬密封蝶閥,閥體和閥座為連體構(gòu)件,
    閥座密封表面層堆焊耐溫、耐蝕合金材料。多層軟疊式密封圈固定在閥板上,這種蝶閥與傳統(tǒng)蝶閥相比具有耐高溫,
    操作輕便,啟閉無磨擦,關(guān)閉時隨著傳動機(jī)構(gòu)的力矩增大來補(bǔ)償密封,提高了蝶閥的密封性能及延長使用壽命的優(yōu)點(diǎn)。
