The use of the double eccentric structure in the butterfly plate so as to the horizontal valve shaft is lifted a little distance above the pipe central line, and it makes that the area of lower half part butterfly plate is bigger than upper part
該閥採用雙便心閥板，水平安裝的閥軸在管道中心線上抬高一定距離，使閥板下半部分迎水面積大於上半部。 -
With the development of the industrial technology, the general soft seal butterfly valve has not been satisfied with the demand in the industry, so the metal seal butterfly vavle has been developed. the tri - eccentric butterfly vavle is the most advanced during the butterfly valve development and evolvement. but, at present, the tri - eccentric butterfly valve has not been studied thoroughly at home, and has not been formed a perfect theory system, brought about the limitation of the tri - eccentric butterfly vavle in its development and application to a great extent
隨著工業技術的發展，普通軟密封蝶閥已滿足不了工業上的需求，金屬硬密封蝶閥很快被開發出來，而三偏心結構蝶閥是蝶閥發展、演化過程中最高級的一種，但是目前國內還沒有對它作深入的研究，還沒有形成一個比較完善的理論分析體系，致使三偏心蝶閥的發展及應用受到一定程度的限制。 -
Since 1998, triple eccentric multiplex ring metal - seat butterfly valve and flanged butterfly valve have been running well all along on - site
自1998年以來，三偏心金屬密封蝶閥法蘭蝶閥等在工礦中一直運行良好。 -
The intervene problem about butterfly plate and pressurized surface is analyzed, and the intervene problem of different structural triple eccentric butterfly valve was expediently judged
通過程序分析了蝶板與閥座密封面之間的干涉狀況，進而能夠很方便地判定不同結構的三偏心蝶閥的干涉情況。 -
The paper deduced the seal torque of the tri - eccentric butterfly valve and gave it a qualitative analysis. the results indicated : for the tri - eccentric butterfly valve with the same caliber, theseal torque would decrease with the butterfly disc thickness increasing ; the seal torque would increase with the radial eccentricity increasing ; however, the axis eccentricity effected on the seal torque minutely ; the seal torque would increase with the half cone angle increasing appreciably of the cone which the butterfly disc belonged to
本文還對三偏心蝶閥的密封力矩作了推導並進行了定性的分析，結果表明，對于同一口徑的三偏心蝶閥，密封力矩與蝶板的厚度近似成反比；與徑向偏心距近似成正比，變化也很明顯；而軸向偏心距對密封力矩的影響不是很大；密封力矩隨著蝶板所在的圓錐半錐角的增大而有所增加。 -
The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
本文主要分析了三偏心蝶閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。 -
Eccentric butterfly valve for heat - supply
供熱用偏心蝶閥 -
Based on the theory analysis above - mentioned, according to the given parameters, we designed the three dementions figure of the tri - eccentric butterfly valve
基於上述的理論分析，由已知參數設計出了三偏心蝶閥的三維圖形。
