1 三偏金屬硬密封蝶

      特點及用途 Feature and usage

     三偏心多層次金屬硬密封蝶閥系列，系我公司新開發(fā)的長壽命、無泄漏、節(jié)能型蝶閥。產(chǎn)品符合國家標準JB/T8527—97（金屬硬密封蝶閥）、FB/T13927—92（通用閥門壓力試驗）標準及閥門其它相關(guān)標準的規(guī)定，結(jié)合國內(nèi)外*技術(shù)，采用三維偏心原理設(shè)計，密封圈采用硬軟密封兼具的多層次結(jié)構(gòu)，適用于介質(zhì)溫度≤65的冶金、電力、石油化工、空氣、煤氣、以及給排水等介質(zhì)管道上作調(diào)節(jié)流體和截斷流體，密封性能可靠，是通用蝶閥向中壓高壓領(lǐng)域的延伸和發(fā)展。

     在此結(jié)構(gòu)基礎(chǔ)上，可采用聚四氟乙烯替代多層次密封圈，形成新一代三偏心四氟密封蝶閥，廣泛應(yīng)用在溫度≤200℃的腐蝕性介質(zhì)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.

1、蝶板密封為硬軟多層，具有硬軟密封雙重密封優(yōu)點，無論在低溫還是在高溫工況下，具有優(yōu)良的密封性能。

2、采用三偏心結(jié)構(gòu)，閥座與蝶板幾乎無摩擦，具有越關(guān)越緊的密封性能，達到零的泄漏。

3、啟閉力矩小、操作靈活、活力節(jié)能，使用壽命長。

4、耐高溫、耐高壓、耐腐蝕適用范圍廣。

5、新一代三偏心私服密封蝶閥兼具了三偏心密封結(jié)構(gòu)與軟密封的優(yōu)點，密封性能可靠，適用范圍廣，使用壽命更長。

6、電動、氣動裝置采用過內(nèi)外名優(yōu)產(chǎn)品，性能更可靠（可有用戶）。

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|）.
