進(jìn)口高壓蝶閥(德國OLES奧萊斯閥門)

【進(jìn)口高壓蝶閥】詳細(xì)說明：

閥門的蝶板在啟閉過程中，實(shí)現(xiàn)了蝶板密封圈與閥座密封面之間的無滑動磨擦·卡擠，密封面上的壓力角大于磨擦角，采用了“徑向動平衡密封系”設(shè)計(jì)，是蝶板開啟阻力極低。啟閉過程中蝶板密封面沿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。開啟密封即可分離，快速準(zhǔn)確實(shí)現(xiàn)關(guān)閉接觸自動相吻合的密封動作。調(diào)節(jié)型多層次·全金屬硬密封蝶閥由于密封面采用多重密封和整體全金屬密封，經(jīng)過高精度機(jī)械加工成橢圓形截面密封環(huán)，它與閥座金屬密封面組成密封副。這種密封結(jié)構(gòu)，在高壓工況下不產(chǎn)生塑性變形，在高溫或低溫工況下，不存在沖壓應(yīng)力、焊接應(yīng)力、彈性退火或咬壞脆裂現(xiàn)象，*解決了傳統(tǒng)蝶閥密封結(jié)構(gòu)不合理引起泄漏的弊病、大大提高了閥門密封可靠性。

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.
