產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features

本雙向蝶閥采取多層次三偏心金屬硬密封結(jié)構(gòu)，不僅具有普通多層次三偏心金屬硬密封蝶閥的全部優(yōu)良性能，由于在設(shè)計(jì)上合理地減小了徑向偏心值，在關(guān)閉狀態(tài)下閥桿所受力矩較小，處于靜平衡，同時(shí)， 蝶板密封圈采用了優(yōu)質(zhì)碳素材料與高韌性不銹鋼組成多層次結(jié)構(gòu)，不僅柔中有剛能與閥座保持密合，而且具有非常良好的自動(dòng)補(bǔ)償功能，特別在較大溫差的工況條件下，可以消除由此引起的結(jié)構(gòu)變形對密封性能的影響，又由于在加工和裝配過程采用了予應(yīng)力方法，使閥門在反向受壓時(shí)產(chǎn)生的相對位移得到充分補(bǔ)償，因此本蝶閥不論正向或反向受壓，均能在全額壓差下達(dá)到泄漏量為零。

This bi-directional take multi-level triple eccentric metal hard seal structure, not only has ordinary multi-layer all excellent properties of triple eccentric metal hard 

seal butterfly valve, due to the design reduces the radial eccentricity value reasonably, in closed valve stem torque is small, in static equilibrium, at the same time, the butterfly plate sealing ring with the high quality carbon materials with high toughness of multi-layer stainless steel structure, not only in the soft just can maintain the best closed with the valve seat, and have a very good self-compensation function, especially under the condition of the working condition of large temperature difference, can eliminate the resulting structure deformation influence on sealing performance, and because of adopted to stress during the process of processing andassembling method, makes the valve in the reverse pressure when the relative displacement be compensated fully, either forward or reverse pressure, therefore this butterfly valve are under full differential pressure to achieve zero leakage.
