This utility model discloses an experimental device for measuring the starting pressure gradient of pulverized coal, relating to the technical field of pulverized coal measuring devices. It includes a storage tank, a feed pipe, an air inlet pipe, a connecting box, a support frame, and an air compressor. The output end of the air compressor is fixedly connected to the connecting box via an air delivery pipe. The connecting box is equipped with a locking mechanism for locking and maintaining the detected data. Through this locking mechanism, this utility model can automatically detect and lock the steadily rising pressure value in the storage tank and the inner cavity of the air inlet pipe during the pressurization of pulverized coal, effectively preventing the detected pressure value from automatically resetting during depressurization. This facilitates maintaining and recording the pressure value under the corresponding state, thereby ensuring the stability and traceability of the pressure data. By conveniently unlocking, the starting pressure gradient of pulverized coal can be remeasured based on the new pressure value, further improving the accuracy and reliability of the measurement.
