The invention provides a novel valve core liquid power measuring system and method, and the system comprises a test oil path module which is used for simulating the working condition of a test valve; the pressure measuring module is mounted at the inlet and outlet of the test valve and used for measuring inlet and outlet pressure of the test valve; the displacement measurement module enables the working direction of a displacement sensor to be the same as the movement direction of the valve core of the test valve and is used for measuring the displacement of the valve core; the data acquisition module is connected with the pressure measurement module and the displacement measurement module, and is used for transmitting the pressure data and the displacement data to a computer; and the hydraulic force calculation module is used for calculating pressure distribution of a working flow field of the test valve by taking pressure and displacement data obtained by an experiment as boundary conditions, and obtaining
