园形橡胶密封结构具有设计简单、密封可靠、使用方便、加工容易等优点,近年来,我们在海洋仪器中越来越多地采用了这种密封方法,并且获得了较好的效果。一、园形密封圈密封原理园形密封圈的几何形状如图1所示。我们一般用D.d分别表示其外径和内径,用W表示 Park-shaped rubber seal structure with simple design, reliable sealing, easy to use, easy processing, etc., in recent years, we are more and more in marine instruments using this method of sealing, and get better results. First, the principle of circular seal ring Park ring geometry shown in Figure 1. We generally use D.d respectively, said the diameter and diameter, with W said
