D973W防爆电动金属硬密封对夹式蝶阀/阀门

多层次硬密封、金属密封弹性蝶阀
产品简介Introduction
蝶阀因其结构紧凑、体积小、重量轻、操作方便、性能可靠、维修简单而广泛应用于热力管道，锅炉辅机系统，石油化工和冶金行业中，用来切断或调节各种腐蚀性和非腐蚀性介质。其产品分中线、单偏心、双偏心和三偏心结构。金属硬密封蝶阀属偏心结构，它是通用软密封蝶阀向中高压领域的延伸和发展，它除了蝶阀原有的特点外，还具有抗老化、搞辐照、经久耐用、寿命长、耐高温高压应用范围广等特点。
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

多层次硬密封蝶阀的特色与优势Characteristic and superiority of multi-layer hard seal butterfly valve
1、多层次硬密封蝶阀密封是采用软硬层金属片层叠组成，通过高精度机械加工成型，嵌装在蝶板上与阀座吻合，具有金属密封和弹性密封的双重优点，无论在低温和高温下，均具有优良的密封性能。
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、采用三维偏心结构，阀座与蝶板几乎无磨擦，具有越关越紧的密封功能。
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、结构紧凑、操作灵活、体积小、重量轻、密封性能可靠、维修方便、使用寿命长。
Compact structure，flexible operation，small volume，light weight，reliable sealing performance，easy repair and long duration
4、设有密封调节装置，长期使用后若密封性能下降，可调节蝶板密封圈向阀座靠近即可恢复原有密封性能，大大搞高了使用寿命。
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、密封副选用不锈钢材料，并在制造过程中采用特殊的工艺处理，具有耐高温、高压、耐磨、耐腐蚀的特点。
The seaI pai r is made of stainIess steeI and P rocessed with a special workmanship during manufacture and features high tempe rature and Pressure resisting anti-wear and anti-corrosion
金属弹性硬密封蝶阀的特色与优势Characteristic and superiority of metal elastic hard seal butterfly valve
金属密封弹性蝶阀伴随着当今世界科学技术的高速发展，以其体积小、重量轻、操作灵活、安装方便、结构简单、抗；中蚀、耐高温等独具魅力的诱人风采展现在世人面前。博纳斯威的金属弹性密封蝶阀以其设计严谨，外形精美时尚，充满时代气息而别具一格倍受青睐.
其突出特点如下：
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、刚性十足、密封可靠：为消除金属密封蝶阀对阀体变形的敏感性，须增加阀体冈0性，本阀采用了高于国家标准蝶阀阀体*小壁厚的企业设计标准，并对阀体内外筋肋进行合理排布，使其刚性十足，从而保证了密封的可靠性。
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、开启自如，操作力矩明显减小，因改进的三偏心蝶板密封曲线更加趋于正圆，这将意味着阀座的变形更趋微量，阀座的实际变形量，远小于金属的弹性范围。从而扩宽了阀座弹性变形的余度，即使在高温状态下也不会超出所用材料的弹性范围。此外，蝶板沿管线的轴向位移也更趋微量，这将减小了阀杆沿流道轴线的挠曲变形量，保证阀杆与轴套的正常接触精度。因些，开启自如，操作力矩远小于其他同类蝶阀产品。这一极具创意的设计思想，使博纳斯威在有些类蝶阀产品的综合质量性能方面有了一个质的飞跃。
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、采用耐高温材料和先进的喷焊技术，使本蝶阀可达到宽广的使用温度范围，因而满足了调温与低温工况条件下的使用要求。
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内件趋于流线的外形设计使本阀耐；中蚀而长寿命。
Use of high hardress materials and the streamline outlook design of the internal parts makes this valve erosion—Proof and long endurable.
