The invention discloses a valve flow distribution crankshaft plunger water hydraulic motor and a working method, and belongs to the technical field of valve flow distribution crankshaft plunger water hydraulic motors. The in-line crankshaft plunger water hydraulic motor is of a plunger structure arranged in the axial direction of a crankshaft and comprises a crankshaft piston part working in an oil lubrication environment and a water power part for driving a crankshaft piston to work through water power, and the crankshaft piston part and the water power part are subjected to oil-water isolation. The plunger flow distribution process is good in sealing performance, high in reliability and good in friction pair lubrication, the working temperature can be effectively reduced, the service life is prolonged, the problems of serious leakage and abrasion of a flow distribution plate and a key friction pair of the water hydraulic motor are solved, and application and reliable service of the water hydraulic motor in
