摘要： A ceramic valve assembly is housed in a recess formed in a metal pipe and is supported via gaskets by the metal pipes. Each gasket has a larger coefficient of linear expansion than that of the metal pipe. A clearance generated due to the thermal expansion difference between the metal pipe and the ceramic housing is absorbed by the large thermal expansion of the gasket so that no play is generated between the ceramic valve assembly and the metal pipe and the sealing force is maintained. Each gasket has beads constructed of spring material. An excessively large load does not act on the ceramic assembly because the beads are deformed to absorb the load.
摘要翻译：陶瓷阀组件容纳在形成在金属管中的凹部中，并通过金属管由垫圈支撑。每个垫片的线膨胀系数都大于金属管。由于金属管和陶瓷壳体之间的热膨胀差产生的间隙被垫圈的大的热膨胀所吸收，使得在陶瓷阀组件和金属管之间不产生冲击并且保持密封力。每个垫圈都有由弹簧材料构成的珠子。过大的负载不会作用在陶瓷组件上，因为小珠变形以吸收负载。
