为了进行密封法兰连接的计算,必须知道橡胶-金属界面处的原始接触应力值,这种应力值取决于密封垫片的变形程度,垫片的弹性模量,摩擦系数,几何尺寸,以及放置垫片的沟槽的结构。本文叙述密封垫部件结构对批生产天然橡胶制造的园截面垫圈,矩形垫圈和方形垫圈变形性能的影响,垫圈内径为60mm。在《邵波尔》型强力试验机上以6mm/分的绝对变形速度压缩垫圈。用刻度为0.01mm的四个钟表型指示器来控制变形程度,以考虑法兰在试验过程中的歪斜状况。
In order to calculate the sealing flange connection, it is necessary to know the original contact stress at the rubber-metal interface, which depends on the degree of deformation of the gasket, the modulus of elasticity of the gasket, the coefficient of friction, the geometric dimensions, The structure of the groove of the gasket. This article describes the effect of gasket structure on the deformation performance of garden section gaskets, rectangular gaskets and square gaskets made of natural rubber. The inner diameter of gaskets is 60mm. The washer is compressed on a “Shoreper” strength tester at an absolute deformation rate of 6 mm / min. With the scale of 0.01mm four clock-type indicator to control the degree of deformation, in order to consider the flange in the process of skew conditions.
