The invention provides a combined valve pressure test device, which comprises a hydraulic clamping module, a
water pressure test module and a transportation track module, and is characterized in that the hydraulic clamping module and the
water pressure test module are respectively arranged at two ends of the transportation track module and are connected into a whole through the transportation track module; the hydraulic clamping module comprises a pressure test table, a bottom plate, a supporting frame, a jack and a
hydraulic pump, the
water pressure test module comprises a water pressure pump, a
water supply carbon steel pipeline, a pressure gauge and a
ball valve, and the transportation track module comprises a track beam and a hoist group. The device comprises a pressure test table with complete tool clamps, a water pressure test module capable of boosting and reducing pressure, and a
rail transportation module for assisting valve clamping and carrying. According to the invention, the pressure test work of two medium / large valves can be simultaneously and independently carried out, the carrying strength of personnel is reduced, the disassembly and
assembly time of the valves is shortened, and the pressure
test efficiency is greatly improved; in addition, the device further has an optimized lifting space, a pressure test water recycling and safety protection device can be additionally arranged, and the device is more
environmentally friendly and
safer.
