气动法兰硬密封蝶阀 D643H D643W

产品详细介绍：

1 三偏金属硬密封蝶
      特点及用途 Feature and usage 1、三偏心多层次金属硬密封蝶阀系列，系我公司新开发的长寿命、无泄漏、节能型蝶阀。产品符合国家标准JB/T8527—97（金属硬密封蝶阀）、FB/T13927—92（通用阀门压力试验）标准及阀门其它相关标准的规定，结合国内外先进技术，采用三维偏心原理设计，密封圈采用硬软密封兼具的多层次结构，适用于介质温度≤65的冶金、电力、石油化工、空气、煤气、以及给排水等介质管道上作调节流体和截断流体，密封性能可靠，是通用蝶阀向中压高压领域的延伸和发展。
     在此结构基础上，可采用聚四氟乙烯替代多层次密封圈，形成新一代三偏心四氟密封蝶阀，广泛应用在温度≤200℃的腐蚀性介质中。
    Three biased multi-level metals hard seal butterfly valves series,is the long life whice the our company newly develops,not divulges,the energy conservation butterfly valve.The product conforms to nation standard JB/T8527-97(metal hardly to seal reed valve),GB/T13927-J92(general valve pressure test)the standard and the valve other correlation standardsStipulations,unifies the domestic and foreign advanced technologies,uses the three dimensional eccentric principle design,The seal packing cllar uses hardly softly seals the concurrently multi-levelstructure,is suitable to the medium temperature<＝65℃ metallurgy,the electric power,the petroleum chemical industry,the air,the coal gas,as well as for medium pipeline on and so on the draining water makes the adjustment current capacity and the interruption fluid,the sealing property is reliable,is the general reed valve presses,center high temperature domain extending to the center with the development.
      In this structure foundation,may use the teflon to substitute the multi-level seal packing collar,forms the new generation of threeBiased four fluorine seals reed valve,widespread application in temperature<＝200℃corrosive medium environment.
     特点 Feature
1、蝶板密封为硬软多层，具有硬软密封双重密封优点，无论在低温还是在高温工况下，具有优良的密封性能。
2、采用三偏心结构，阀座与蝶板几乎无摩擦，具有越关越紧的密封性能，达到零的泄漏。
3、启闭力矩小、操作灵活、活力节能，使用寿命长。
4、耐高温、耐高压、耐腐蚀适用范围广。
5、新一代三偏心私服密封蝶阀兼具了三偏心密封结构与软密封的优点，密封性能可靠，适用范围广，使用寿命更长。
6、电动、气动装置采用过内外名优产品，性能更可靠（可有用户指定）。
1,The butterfly board seal packing collar for hard is soft double-decked,has the hard soft seal dual merit,regardless of in the low temperature orunder the high
Temperature operating mode,has the fine sealing property.
2,Use three eccentric structures,the valve seat and the butterfly board nearly no friction,has the pass tighter sealing property,achieved zero divulges.
3,Opens shuts the moment of force slightly the operation nimble,the vigor energy conservation,the service life is longer.
4,Thermostable,bears the high pressure,the anti-corrosive applicable scope is broad,5th,the new generation of three biased four fluorine seals reed valve concurrentfly has had three biased seals sturcture and the soft seal merit,the sealing property more reliable,the applicable scope broader,the service life is longer,6th,electrically operated,the pneumatics use the domestic and foreign famous products,performance is more reliable(may assign by user|).
