產(chǎn)品用途

焊接蝶閥采用精密的J形彈性密封圈和三偏心多層次金屬硬密封結(jié)構(gòu)，被廣泛用于介質(zhì)溫度≤425℃的治金、電力、石油化工、

以及給排水和市政建設(shè)等工業(yè)管道上，作調(diào)節(jié)流量和載斷流體使用

產(chǎn)品特點(diǎn)

1、焊接蝶閥，閥座與蝶板幾乎無磨損，具有越觀越緊的密封功能

2、密封圈選用不銹鋼制作，具有金屬硬密封和彈性密封的雙重優(yōu)點(diǎn)，無論在低溫和高溫的情況下，

均具有優(yōu)良的密封性能，具有耐腐蝕,使用壽命長等特點(diǎn)

3、蝶板密封面采用堆焊鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長

4、大規(guī)格蝶板采用絎架結(jié)構(gòu)，強(qiáng)度高，過流面積大，流阻小

5焊接蝶閥安裝時(shí)不受介質(zhì)流向的限制，也不受空間位置的影響，可在任何方向安裝

6、驅(qū)動(dòng)裝置可以多工位（旋轉(zhuǎn)90°或180°）安裝，便于用戶使用
