Rubber sleeve sealing performance detection device

The utility model belongs to the technical field of oil and gas well tools, and particularly relates to a rubber sleeve sealing performance detection device. The rubber sleeve sealing performance detection device comprises a sleeve assembly, an inner assembly, a loading rod, a liquid supply system and the like. The rubber sleeve arranged on the outer side of the inverted hanging rod in a sleeving mode can respond to liquid from the liquid supply system to expand and abut against the inner wall of the upper connector, and the liquid supply system can apply pressure to the upper side or the lower side of the rubber sleeve in different pressing modes so that the sealing performance of the expanded rubber sleeve can be detected. In addition, the device for detecting the sealing performance of the rubber sleeve also has a heating function. In a word, the technical scheme provided by the utility model can simulate a real underground water plugging environment, so that the detection result of the sealing performance
