It is international initiative and has the following salient features:做为核心的

8、陶瓷芯体，我们采用了独特的内盲孔大倾角设计，为国际首创，具有以下几个显著的特征：Change the traditional bottom sealing within an awl hole as a sealing surface to make the core body were in a quasi-floating state normally and the core were almost no axial force.改变了传统的底面密封方式，以内盲孔环面做为密封面，使得芯体在常态下处于准浮动状态，芯体轴向几乎不受力。 Use small diameter O-ring se

9、als, sealing more reliable.采用小直径O 型密封圈密封，密封更加可靠。Installation of axial and radial structure will allow a high margin of error.安装结构轴向和径向均允许有较大的误差。Can also play a positive pressure and negative pressure sealed role.可同时起到正压和负压的密封作用。Due to the effective sealing surface areas derision, shell axial force d
