美标蝶阀

美标蝶阀】是蝶阀旗下产品,我们可为客户提供相关气动美标蝶阀,美标法兰蝶阀,美标凸耳蝶阀、标准、作用、结构图、规格、型号、外形尺寸、工作原理、说明书、欢迎来电咨询、采购。

  美标蝶阀采用三维偏心斜锥形阀座密封,蝶板密封采用新型金属片与弹性材料层叠而成,嵌装在蝶板上与阀座吻合。利用蝶板摆动压紧密封,所以密封面摩擦阻力小,关闭时具有越关越紧功能,这样密封性可靠,开启确保密封面完全脱离接触,保证了密封面不受损伤。美标蝶阀结构特点排除了其他类型蝶阀开过位而不能密封的缺点,且在高曙下能正常使用,克服了其它类型阀门在高温使用时因热膨胀而容易泄漏的缺点。

  American Standard Butterfly Valve Adopts Three-dimensional Eccentric Conical Seat Seal. Butterfly Plate Seal Is Laminated With New Metal Sheet And Elastic Material, Which Is Embedded On The Butterfly Plate And Fits The Valve Seat. The Butterfly Plate Is Used To Swing And Compress The Seal, So The Friction Resistance Of The Sealing Surface Is Small, And The More Close The Sealing Surface Is, The Closer The Sealing Is, The More Reliable The Sealing Performance Is. The Sealing Surface Is Completely Separated From The Contact By Opening, And The Sealing Surface Is Not Damaged. The Structure Of American Standard Butterfly Valve Eliminates The Defect That Other Types Of Butterfly Valves Can Not Be Sealed Due To Over Opening, And Can Be Used Normally Under High Temperature, Which Overcomes The Defect Of Easy Leakage Of Other Types Of Valves Due To Thermal Expansion When Using At High Temperature.
