Valve block of multifunctional large-flow-interval multi-way valve test hydraulic loading system

The invention relates to a valve block of a multifunctional large-flow-interval multi-way valve test hydraulic loading system. Multi-way valve single-connection A1-T and B1-T can be realized through linkage control of valve block plug-ins, matching with a test part P1-A1-B1-T, a pressure and flow stable oil source can be directly supplied to the test part by A1 and B1 of the loading valve block, P1 and P2 double-source combined flow can be achieved when oil is supplied to the outside, oil can be supplied to the tested part by P1', loading is carried out by A2 and B2, so that various mode loading of the oil quantity distinguishing condition of the actual working condition of the tested part is simulated. According to the technical scheme, the flow coverage range is wide, the problem that multiple test items need to pipe connecting for many times in the test process is effectively solved, the workload is reduced, the pollution to the hydraulic system is reduced, and the production efficiency is improved.
