The invention relates to a VR-environment-based process control experiment teaching method and system. The method comprises the following steps: in a preset area, executing a virtual experiment operation through a control handle; to obtain experiment information in the experiment operation by a signal connecting device, and sending the experiment information to an algorithm integration simulationdevice; according to the experiment information, simulating and calculating an experiment result, judging whether the experiment result is within a preset value, if so, displaying the experiment result; if not, feeding back a corresponding control signal to a controller, and controlling a user to adjust the corresponding experiment operation. The system comprises a VR input control device, the signal connecting device, the algorithm integration simulation device and a display device. Through the method and system, under the VR environment, the equipment construction and a pipeline hand valve and so on can be flexibly arranged, the operation is convenient, the experiment time is saved, the place, various raw materials and facilities are saved, and the experiment cost is greatly reduced.
