High-load hydraulic tension test system

The invention relates to the technical field of experiment equipment, in particular to a high-load hydraulic tension test system. The high-load hydraulic tension test system comprises a tension machine assembly, a remote control system and two pressure circular disc recording instruments, wherein the tension machine assembly is communicated with the remote control system through an upper interface, a lower interface, a side flange and a pressure-resistant pipeline; the two pressure circular disc recording instruments are respectively communicated with the upper interface and the lower interface through the pressure-resistant pipeline and the side flange; a load four-way valve is arranged on the top of the tension machine assembly, and is connected with a hydraulic body through positioningscrew bolts; a piston of the hydraulic body is connected with a test product sequentially through a piston rod, a conversion joint, a connecting pin and a pressure test plug; a lip-shaped sealing ringis arranged on the inner
