摘要： Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.
摘要翻译：用于高压应用的密封系统，其在接合元件之间提供电隔离，以及在火灾期间增强对介质泄漏的抵抗力。使用金属芯实现高压密封，其中电绝缘材料在两侧或两侧上结合。通过绝缘密封元件（例如弹簧加载的聚四氟乙烯（PTFE））环来实现密封。接头的法兰可以用插入其间的密封件螺栓连接在一起，并且凸缘螺栓连接在一起。在发生火灾的情况下，可能会产生足够高的温度以消除隔离材料和PTFE环的热量。各种实施例的系统提供金属芯备用密封件和压缩限制器，其分别防止介质从接头泄漏并且保持法兰处的螺栓负载。

摘要： A seal device is generally provided a seal member having multiple sealing faces, a central aperture, and an outer edge. A radially inner channel of various geometries may be formed that is open to the central aperture to provide a pressure-energized seal when a pressurized fluid enters the channel. A seal retainer may be partially disposed within a radially outer groove in the radially outer edge of the seal member. The seal retainer may have a rigid core that is at least partially coated with a non-corrosive material. Secondary seals may be engaged with the seal retainer in a radially outwardly spaced relationship with the seal member. The secondary seals may be heat-resistant.
摘要翻译：密封装置通常设置有具有多个密封面，中心孔和外边缘的密封构件。可以形成各种几何形状的径向内部通道，该通道对中心孔是开放的，以在加压流体进入通道时提供加压的密封。密封保持器可以部分地设置在密封构件的径向外边缘中的径向外部凹槽内。密封保持器可以具有至少部分地涂覆有非腐蚀性材料的刚性芯。二次密封件可以与密封件保持器以与密封构件径向向外间隔的关系接合。二次密封件可以是耐热的。

摘要： A molded discrete low stress gasket is constructed of restructured filled PTFE for use in corrosive or severe chemical environments under relatively low bolt loads. The gasket has a gasket surface and includes a raised outer sealing ring and a raised inner sealing ring. The gasket may constructed from a restructured filled PTFE material, with the sealing rings deforming at lower pressures than the remaining portions of the gasket.
摘要翻译：模制的离散低应力垫圈由重组的填充PTFE构成，用于在较低的螺栓载荷下用于腐蚀性或严重的化学环境。垫圈具有垫圈表面，并且包括凸起的外密封环和凸起的内密封环。垫圈可以由重组的填充PTFE材料构成，密封环在比垫圈的其余部分低的压力下变形。
