进口高压蝶阀(德国OLES奥莱斯阀门)
【进口高压蝶阀】详细说明：
阀门的蝶板在启闭过程中，实现了蝶板密封圈与阀座密封面之间的无滑动磨擦·卡挤，密封面上的压力角大于磨擦角，采用了“径向动平衡密封系”设计，是蝶板开启阻力极低。启闭过程中蝶板密封面沿360°圆周各点可以瞬间快速完成，逐点接触和逐点脱离。开启密封即可分离，快速准确实现关闭接触自动相吻合的密封动作。调节型多层次·全金属硬密封蝶阀由于密封面采用多重密封和整体全金属密封，经过高精度机械加工成椭圆形截面密封环，它与阀座金属密封面组成密封副。这种密封结构，在高压工况下不产生塑性变形，在高温或低温工况下，不存在冲压应力、焊接应力、弹性退火或咬坏脆裂现象，*解决了传统蝶阀密封结构不合理引起泄漏的弊病、大大提高了阀门密封可靠性。
During the opening and closing process of the butterfly plate of the valve, the non-sliding friction and jamming between the butterfly plate seal ring and the sealing surface of the valve seat are realized. The pressure angle on the sealing surface is larger than the friction angle. The design of "radial dynamic balance seal system" is adopted, which makes the opening resistance of the butterfly plate very low. During the opening and closing process, the sealing surface of butterfly plate along 360 degree circumference can be completed instantaneously and quickly, point by point contact and point by point detachment. The seal can be separated by opening the seal, which can quickly and accurately realize the sealing action of automatic coincidence of the closed contact. Adjustable multi-level all-metal hard-sealed butterfly valves are machined into elliptical cross-section sealing rings with high precision due to multiple seals and overall all-metal seals on the sealing surface, which form a sealing pair with the metal seating surface of the valve seat. The sealing structure does not produce plastic deformation under high pressure condition, and does not exist stamping stress, welding stress, elastic annealing or bite brittle cracking under high or low temperature condition. It completely solves the defect of leakage caused by unreasonable traditional butterfly valve sealing structure and greatly improves the reliability of valve sealing.
