Multi-occasion valve testing device

The utility model discloses a multi-occasion valve testing device, which relates to the technical field of valve testing and comprises a heat preservation testing box, a compressed air testing pipeline, a high-temperature gas testing pipeline, a liquid testing pipeline, a detachable gas cylinder group and an LNG (liquefied natural gas) storage tank testing pipeline. The recycling of the gas and the repeated use of the liquid are realized through the circulation loop, and a physical environment consistent with the use working condition can be created for the testing device, so that the service life of the valve is favorably prolonged, and the waste of resources is reduced. 本实用新型公开了一种多场合阀门测试装置，涉及阀门测试技术领域，包括保温测试箱、压缩空气测试管路、高温气体测试管路、液体测试管路、可拆装气瓶组、LNG储罐测试管路，四条管路之间互相补充，并通过循环回路实现气体的回收利用和液体的重复使用，也能为测试装置创造一个与使用工况相一致的物理环境，有利于提高阀门的使用寿命，减少资源的浪费。
