API美標對夾蝶閥產品概述
美標對夾蝶閥采用三維偏心斜錐形閥座密封副,蝶板密封采用新型金屬片與彈性材料層疊而成,嵌裝在蝶板上與閥座吻合。利用蝶板擺動壓緊密封,所以密封面摩擦阻力小,關閉是具有越關越緊功能,這樣密封性能可靠,開啟確保密封面脫離接觸,保證了密封面不受損傷。 美標對夾蝶閥廣泛適用于低壓、中壓、高壓、鋼鐵冶金、石油、化工、電力等工業管道上作截斷或調節介質流量用。
美標對夾蝶閥產品特點
1、密封可調節,10萬次壽命無泄漏:
2、特殊密封結構,在高溫和冷態工作況下,密封無應力變形,達到零泄漏;
3、三維偏心結構,開啟密封即分離,關閉接觸即密封;
4、軸向定位裝置,解決軸向密封面磨損易泄漏的難題,傳動執行器可朝任意向方安裝;
5、適用于食品、醫藥、化工等凈管路及工業環保、水處理、高層建筑、給排水管路作啟閉或調節介質流量之用。
