主要零件和材質 Main parts and materials 產品結構特點 Construction features 本雙向蝶閥采取多層次三偏心金屬硬密封結構，不僅具有普通多層次三偏心金屬硬密封蝶閥的全部優良性能，由于在設計上合理地減小了徑向偏心值，在關閉狀態下閥桿所受力矩較小，處于靜平衡，同時， 蝶板密封圈采用了優質碳素材料與高韌性不銹鋼組成多層次結構，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補償功能，特別在較大溫差的工況條件下，可以消除由此引起的結構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力方法，使閥門在反向受壓時產生的相對位移得到充分補償，因此本蝶閥不論正向或反向受壓，均能在全額壓差下達到泄漏量為零。 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 and assembling method, makes the valve in the reverse pressure when the relative displacement be compensated fully, either forward or reverse pressure, therefore thisbutterfly valve are under full differential pressure to achieve zero leakage. 產品特征 Spericfications 適用介質：水、氣、油品、天然氣和酸堿腐蝕性介質 適用溫度：-196~350℃ 驅動方式：手動、氣動、電動、液動等 公稱壓力：0.6~4.0MPa 公稱通徑：DN100~4500mm Applicable media: water, gas, oil, gas and acid and alkali corrosive medium Applicable temperature: -196~350℃ Driver: manual, pneumatic, electric, hydraulic, etc Nominal pressure: 0.6~4.0MPa Nominal size: DN100~4500mm 技術規范 Technical specification 試驗壓力 Test prssure 蝶閥結構長度和外接尺寸 Main connection dimensions
