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 Metal seated butterfly valve adopts a double eccentric structure and a inclined cone seal. The seal-ring can be separated once open the disk, and the valve can be sealed once the seal-ring contacts the disk. This structure can decrease the friction torque when the butterfly valve opens and closes, and expanded the life time, and make opening and closing easily.

斜锥面金属密封蝶阀设计采用了一个双偏心和一个特殊斜锥椭圆密封结构，实现蝶板在开启瞬间密封面即分离，关闭接触即密封的效果，这种密封结构实现启闭无机械滑动摩擦，大大延长了密封件的使用寿命，并且达到启闭轻松自如目的，且具有密封自动补偿功能。

Why do people have the inspiration to make liquid seals ? First of all, no matter how tight you press the solid seals , they can't fill in those uneven places on the joint face, so gap always exists. But liquid seals can fill in the dent and present good sealing function. Meanwhile liquid seals have stickiness so they have adhesive force to metal adjoining planes, which is helpful to seal. Besides the stickiness of liquid seals is high so they will not move easily, which can ensure the leak tightness.

人们之所以会有液体密封件的灵感，首先是考虑到固体密封件无论怎样压紧，也不能完全填满接合面上的凹凸不平，在界面上总会存有间隙，而液态密封件却能将全部凹陷填平，呈现出良好的密封效果；同时，液态密封件具有一定的粘性，对金属接合面具有一定的粘附力，有利于密封，而且液态密封件的粘度是很高的，很难发生流动，从而进一步保证了密封性。
