德國(guó)奧萊斯OLES進(jìn)口高壓蝶閥
【進(jìn)口高壓蝶閥】詳細(xì)說(shuō)明：
閥門(mén)的蝶板在啟閉過(guò)程中，實(shí)現(xiàn)了蝶板密封圈與閥座密封面之間的無(wú)滑動(dòng)磨擦·卡擠，密封面上的壓力角大于磨擦角，采用了“徑向動(dòng)平衡密封系”設(shè)計(jì)，是蝶板開(kāi)啟阻力極低。啟閉過(guò)程中蝶板密封面沿360°圓周各點(diǎn)可以瞬間快速完成，逐點(diǎn)接觸和逐點(diǎn)脫離。

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.
