多層(ceng)次硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)蝶(die)(die)(die)(die)閥(fa)為偏心(xin)金(jin)(jin)(jin)屬(shu)(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)結(jie)構，密(mi)(mi)(mi)封(feng)(feng)(feng)形(xing)式為金(jin)(jin)(jin)屬(shu)(shu)對金(jin)(jin)(jin)屬(shu)(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)，可調換金(jin)(jin)(jin)屬(shu)(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)對金(jin)(jin)(jin)屬(shu)(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)，不銹鋼板(ban)(ban)與石(shi)墨(mo)復合板(ban)(ban)密(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)對金(jin)(jin)(jin)屬(shu)(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)。硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)蝶(die)(die)(die)(die)閥(fa)的驅動(dong)形(xing)式除(chu)了電動(dong)之(zhi)外(wai)還有(you)：手動(dong)，蝸輪(lun)桿傳動(dong)，氣動(dong)等(deng)。 多層(ceng)次硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)蝶(die)(die)(die)(die)閥(fa)的蝶(die)(die)(die)(die)板(ban)(ban)安裝(zhuang)于管(guan)道的直徑方(fang)向。在(zai)蝶(die)(die)(die)(die)閥(fa)閥(fa)體(ti)圓柱形(xing)通道內，圓盤形(xing)蝶(die)(die)(die)(die)板(ban)(ban)繞(rao)著(zhu)軸線旋(xuan)轉(zhuan)(zhuan)(zhuan)，旋(xuan)轉(zhuan)(zhuan)(zhuan)角度(du)為0°~90°之(zhi)間(jian)，旋(xuan)轉(zhuan)(zhuan)(zhuan)到90°時，閥(fa)門則牌全開狀態。

多層次硬密(mi)(mi)封(feng)(feng)(feng)蝶(die)閥(fa)為(wei)偏心金屬(shu)(shu)密(mi)(mi)封(feng)(feng)(feng)結(jie)構,密(mi)(mi)封(feng)(feng)(feng)形式(shi)為(wei)金屬(shu)(shu)對(dui)(dui)(dui)金屬(shu)(shu)密(mi)(mi)封(feng)(feng)(feng),可調換金屬(shu)(shu)密(mi)(mi)封(feng)(feng)(feng)圈(quan)對(dui)(dui)(dui)金屬(shu)(shu)密(mi)(mi)封(feng)(feng)(feng),不銹鋼板與石(shi)墨復合板密(mi)(mi)封(feng)(feng)(feng)圈(quan)對(dui)(dui)(dui)金屬(shu)(shu)密(mi)(mi)封(feng)(feng)(feng).硬密(mi)(mi)封(feng)(feng)(feng)蝶(die)閥(fa)的驅動(dong)形式(shi)除了電動(dong)之外還有：手動(dong),蝸(gua)輪(lun)桿(gan)傳(chuan)動(dong),氣(qi)動(dong)等。

多層(ceng)次硬密(mi)封蝶(die)閥的蝶(die)板安裝于管(guan)道的直徑方向。在蝶(die)閥閥體圓(yuan)柱(zhu)形(xing)通道內，圓(yuan)盤形(xing)蝶(die)板繞著軸(zhou)線旋轉，旋轉角(jiao)度為0°~90°;之間，旋轉到90°時，閥門(men)則牌全開狀態。

多層次法蘭金屬硬密封蝶閥主要性能特點： 
1．結構*、型小輕便、操作靈活、省力、方便； 
2．密封可靠，可達到氣密封無泄漏； 
3．流量特性趨于直線調節性有； 
4．采用三偏心原理，使密封面近似零靡損延長了閥門的使用壽命； 
5．應用范圍廣。如：可用于水、蒸氣、油品、空氣、煤氣等介質。 
6．適用不同溫度及6.4MPa以下的壓力等級，耐腐蝕等各種介質管線。
