密封材料

The rubber seal issue under operating system has been studied by the theory of dynamic sealing. The deformation and stress distribution of rubber material were calculated under the well in-pressure and sealing out-pressure using then-linear finite element. Through the experimental study of the rubber strength and fatigue, the intensity limit and the fatigue life were obtained. According to the study results, a new type of sealing equipment was designed by adding the reinforcing steel bar into rubber core to reduce the maximum shear stress, so as to solve the problems of dynamic seal under hyperbaric pressure.

采用动态密封理论，针对带压作业系统中的橡胶密封胶芯问题，利用非线性有限元计算了在井压和密封外压作用下的变形和应力分布特征，并通过对密封胶芯材料进行了强度和疲劳实验研究，获得了胶芯材料破坏的原因，进而根据计算和实验研究结果，进一步提出了在胶芯内增加钢筋以减小最大剪切力的改进意见，同时进行了理论校核，并以此为基础设计了新型的密封胶芯，从而解决了带压作业装置高压动密封的难题。

The so-called plasticity seal, the seal is the sealing surface pressure is equal Sealing than the soft material yield limit, so that Pressure sealing globe valve joint surface in close contact, use the plastic deformation of soft materials, blockage hardware uneven surface, giving rise to approximate the ideal plane, and produce equivalent soft material yield limit of the reaction and remain sealed.

所谓塑性法密封，就是密封面的密封比压等于密封副软材料的屈服极限，使结合面紧密接触，利用软材料的塑变而堵塞硬件表面的不平处，形成近似理想平面，并产生等于软材料屈服极限的反力而保持密封。

Some documents like the Hermetic materials seem to evidence very few influences from Christianity, whereas a few documents, such as the Sophia of Jesus, may be Christianized redactions of earlier non - Christian documents.

一些文件如密封材料的证据似乎很少从基督教的影响，而一些文件，如耶稣的索菲亚，可Christianized删节以前的非-基督教的文件。
