氣(qi)(qi)動硬密(mi)(mi)(mi)封(feng)(feng)蝶(die)閥結(jie)構新穎(ying)，閥體構造為滿足管道空間狹窄而形成的短(duan)距離對夾(jia)式結(jie)構，可(ke)有xiao降低成本(ben)，具有重量輕、價格低.適(shi)合大口徑工況(kuang)中作為開關閥使用。氣(qi)(qi)動對夾(jia)式蝶(die)闊(kuo)可(ke)分為氣(qi)(qi)動軟(ruan)密(mi)(mi)(mi)封(feng)(feng)蝶(die)閥和氣(qi)(qi)動硬密(mi)(mi)(mi)封(feng)(feng)蝶(die)閥兩種，軟(ruan)密(mi)(mi)(mi)封(feng)(feng)結(jie)構適(shi)用于水、液體等常(chang)溫場合，硬密(mi)(mi)(mi)封(feng)(feng)結(jie)構適(shi)用于蒸汽、空氣(qi)(qi)、導(dao)熱油等高溫場合。

氣動硬密(mi)封(feng)蝶閥的工作原(yuan)理:

氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)蝶(die)閥(fa)(fa)(fa)(fa)由氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)執(zhi)行(xing)器、蝶(die)閥(fa)(fa)(fa)(fa)、附(fu)件三部分組成，工作以壓縮(suo)空氣(qi)(qi)(qi)為動(dong)(dong)(dong)(dong)力(li)，氣(qi)(qi)(qi)缸為執(zhi)行(xing)器，結(jie)(jie)合蝶(die)閥(fa)(fa)(fa)(fa)做90度旋轉運動(dong)(dong)(dong)(dong)，該閥(fa)(fa)(fa)(fa)一般作為管線截(jie)斷使用(yong)，也可加定位器作為簡單調節使用(yong)。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)蝶(die)闊(kuo)主(zhu)要分為氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)調節蝶(die)閥(fa)(fa)(fa)(fa)、氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)對(dui)夾式蝶(die)閥(fa)(fa)(fa)(fa)、氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)法蘭蝶(die)閥(fa)(fa)(fa)(fa)、氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)硬密封(feng)蝶(die)閥(fa)(fa)(fa)(fa)等。該閥(fa)(fa)(fa)(fa)的特點是結(jie)(jie)構(gou)簡單、價格低(di)、適合大口徑場(chang)合。
