Gate structure water seal characteristic test device

The invention discloses a gate structure water seal characteristic test device which comprises a test device body, simulated pressure boxes, gate mounting bases and a detection box, the middle part of the test device body is fixedly connected with a shell, the middle part of the top in the shell is fixedly connected with the detection box, and the two sides of the detection box are fixedly connected with the gate mounting bases. The two sides of the top of the interior of the shell are fixedly connected with the simulated pressure boxes, the tops of the simulated pressure boxes are fixedly connected with pressurization pressure reducers, and the pressurization pressure reducers can suck a water source in the water storage tank through a water feeding pump for use. The water source in the water storage tank is pumped out by a water suction pump from redundant water flow in the corresponding detection box and the simulated pressure boxes so that compared with an existing test device, the same water can be used
