Testing device for compression set of rubber in medium environment

A test device for compression set of rubber in a medium environment comprises a container, the container is sealed through a cover plate, a sealing piece and a fastener I, a valve is installed on the container, a compression device is placed in an inner cavity of the container, and a pressure gauge and a thermocouple are arranged on the cover plate. The device has the beneficial effects that the device comprehensively considers the influence of a medium and compression on a sample, the test environment is closer to the actual use condition, and the test result can better represent the rubber use condition. 一种橡胶在介质环境下压缩永久变形的试验装置，包括容器，容器通过盖板、密封件、紧固件Ⅰ进行封闭，容器上装有阀门，容器的内腔放置压缩装置，盖板上设有压力表、热电偶。本发明的有益效果是，本装置综合考虑了介质和压缩对试样的影响，测试环境更接近实际使用工况，测试结果更能表征橡胶使用情况。
