D973W防爆電動金屬硬密封對夾式蝶閥/閥門

多層次硬密封、金屬密封彈性蝶閥
產(chǎn)品簡介Introduction
蝶閥因其結構緊湊、體積小、重量輕、操作方便、性能可靠、維修簡單而廣泛應用于熱力管道，鍋爐輔機系統(tǒng)，石油化工和冶金行業(yè)中，用來切斷或調(diào)節(jié)各種腐蝕性和非腐蝕性介質(zhì)。其產(chǎn)品分中線、單偏心、雙偏心和三偏心結構。金屬硬密封蝶閥屬偏心結構，它是通用軟密封蝶閥向中高壓領域的延伸和發(fā)展，它除了蝶閥原有的特點外，還具有抗老化、搞輻照、經(jīng)久耐用、壽命長、耐高溫高壓應用范圍廣等特點。
Because of a compact structure，a small volume，a light weight，easy operation，reliable performance and easy repair etc. features with the butterfly valve，it is broadly applied for the rmodynamic pipelines，boiler donkey engine system，petrochemica ndustry and metallurgy trade to cut off and adjust various corrosive and non-corrosive media There a recent ralline，single-eccentric dual-eccentric and three-eccentric types of its structure The metal hard seal butte rfly valve belongs to the eccentric structure and comes as the extension and development of the unive rsal soft seal butterfly valve towards the middle and high pressure fields In addition to the original features with the butterfly valve，it also holds anti—aging，anti—radiation，durability，a long duration，high temperature and pressure resisting and a wide range of application

多層次硬密封蝶閥的特色與優(yōu)勢Characteristic and superiority of multi-layer hard seal butterfly valve
1、多層次硬密封蝶閥密封是采用軟硬層金屬片層疊組成，通過高精度機械加工成型，嵌裝在蝶板上與閥座吻合，具有金屬密封和彈性密封的雙重優(yōu)點，無論在低溫和高溫下，均具有優(yōu)良的密封性能。
The seal of the said valve is formed by laminating soft and hard metal sheets and high p recisely mechanical p rocessing and inlaid onto the butte rfly Plate to get fitted closely with the seat ring It holds the advantages of both metal and elastic seals and，whether in a low or high temperature，a good tightness
2、采用三維偏心結構，閥座與蝶板幾乎無磨擦，具有越關越緊的密封功能。
Because of the three-eccentric structure，there is almost no friction between both seat ring and butte rfly Plate and such a sealing function as the mo re cIosed，the tighter
3、結構緊湊、操作靈活、體積小、重量輕、密封性能可靠、維修方便、使用壽命長。
Compact structure，flexible operation，small volume，light weight，reliable sealing performance，easy repair and long duration
4、設有密封調(diào)節(jié)裝置，長期使用后若密封性能下降，可調(diào)節(jié)蝶板密封圈向閥座靠近即可恢復原有密封性能，大大搞高了使用壽命。
Set with a sealing adjuster and，in case of the sealing performance to be lowered after a long time of use，the original performance can be reset just adjusting the butterfly Plate seal ring to close to the seatring，greatly enhancing the du ration
5、密封副選用不銹鋼材料，并在制造過程中采用特殊的工藝處理，具有耐高溫、高壓、耐磨、耐腐蝕的特點。

金屬彈性硬密封蝶閥的特色與優(yōu)勢Characteristic and superiority of metal elastic hard seal butterfly valve
金屬密封彈性蝶閥伴隨著當今世界科學技術的高速發(fā)展，以其體積小、重量輕、操作靈活、安裝方便、結構簡單、抗；中蝕、耐高溫等獨具魅力的誘人風采展現(xiàn)在世人面前。博納斯威的金屬彈性密封蝶閥以其設計嚴謹，外形精美時尚，充滿時代氣息而別具一格倍受青睞.
其突出特點如下：
Along with the cu r rent world science and technique development at a very fast speed，the metal elastic hard seal butterfly valve comes into being with such unique glamour and captivating mien as small volume，light weight，flexible ope ration，easy installation，simple structure，erosion resisting and high temperatu re resisting The metal elastic hard seal butterfly valve of Be rnaswe holds a
distinctive style and gets a high favo r by its p recise design，nice and fashionable outlook and fu||times flavo r and the outstanding features of it are shown below：
1、剛性十足、密封可靠：為消除金屬密封蝶閥對閥體變形的敏感性，須增加閥體岡0性，本閥采用了高于國家標準蝶閥閥體*小壁厚的企業(yè)設計標準，并對閥體內(nèi)外筋肋進行合理排布，使其剛性十足，從而保證了密封的可靠性。
Complete rigidity，reliable seal：to eliminate the sensitiveness of the metal seal butterfly valve to the body deformation，the body rigidity must be reinforced This valve adopts the enterp rise design standard with the minimum wall thickness of the body higher than that in the national standard fo r butte rfly valves and makes the inte rnal and exte rnal ribs of the body reasonably arranged to have it completely rigid，thusensu ring the reliability of the seal
2、開啟自如，操作力矩明顯減小，因改進的三偏心蝶板密封曲線更加趨于正圓，這將意味著閥座的變形更趨微量，閥座的實際變形量，遠小于金屬的彈性范圍。從而擴寬了閥座彈性變形的余度，即使在高溫狀態(tài)下也不會超出所用材料的彈性范圍。 此外，蝶板沿管線的軸向位移也更趨微量，這將減小了閥桿沿流道軸線的撓曲變形量，保證閥桿與軸套的正常接觸精度。因些，開啟自如，操作力矩遠小于其他同類蝶閥產(chǎn)品。這一極具創(chuàng)意的設計思想，使博納斯威在有些類蝶閥產(chǎn)品的綜合質(zhì)量性能方面有了一個質(zhì)的飛躍。
Freely opened the ope ration moment gets notably reduced and the imp roved sealing curve of the three-eccentr Jc butterfly valve becomes more round This means the defo rmation of the seat ring becomes mo re slight and the actual deformation degree is far from the range of the metal elasticity，thus getting the margin of the elastic deformation of the seat ring widened and willnot be over the elastic range of the used mate rial，even if in a high temperature Besides，the axial displacement of the butterfly Plate along with the Pipeline also becomes more slighf to reduce the flexing deformation of the stem along with the axis of the runner and make su re of the normal contacting accu racy between both stem and muff So it can be freely opened with the ope ration moment much smaller than that of the other butterfly valves of the same type This design idea of an ext remely creativeness makes the complex quality Prope rty of some kinds of butte rfly valves of Be rnaswe a qualitative leap
3、采用耐高溫材料和先進的噴焊技術，使本蝶閥可達到寬廣的使用溫度范圍，因而滿足了調(diào)溫與低溫工況條件下的使用要求。
Use of high tempe ratu re resisting mate rials and advanced jet-solde ring technique makes this butterfly valve to a wide temperature range and thus satisfying the requi rements of temp rature adiustment and to be used in a low temperature working condition
4、高硬度材料的使用和內(nèi)件趨于流線的外形設計使本閥耐；中蝕而長壽命。
Use of high hardress materials and the streamline outlook design of the internal parts makes this valve erosion—Proof and long endurable.
