Device for measuring permeability of sample

The utility model provides a device for measuring the permeability of a sample, which comprises a detection bin, a bin cap, a piston component capable of dividing the detection bin into a first space and a second space for placing the sample, a channel communicated with the first space and a first joint communicated with the channel and used for injecting test fluid, the second connector is used for injecting driving fluid into the second space; and the third connector is used for receiving test fluid. The piston assembly is configured to enable the sample to cover the second through hole under the action of the driving fluid, and the testing fluid penetrates through the sample under the action of the first connector and flows into the third connector. The device has the advantages of being fast to assemble and disassemble, and capable of simulating various different static pressure compaction conditions. 本实用新型提供了一种用于测量样品渗透率的装置，包括检测仓，仓帽，能够将检测仓分割成用于放置样品的第一空间与第二空间的活塞组件，在活塞组件内形成有与第一空间连通的通道，与通道连通并用于注入测试流体的第一接头，用于
