The utility model relates to a check valve reliability testing arrangement. The utility model provides an output of low pressurized air source and the pressure -bearing union coupling for the input of low pressure valve, the output of low pressure valve and the pressure -bearing union coupling for the control end of the check valve of examination that awaits measuring, the await measuring pressure -bearing union coupling output for of input and the forward valve of the check valve of examination, the pressure -bearing for the output of the check valve of examination that awaits measuring is managed and is connected reversing valve's the output and the input of relief valve jointly, the pressure sensor's of the input of forward valve and the common connecting band gauge outfit of reversing valve's pressure -bearing for input pipe output, take the pressure sensor's of gauge outfit the input and the pressure -bearing union coupling for the output of high pressurized air source, control center respectively with low pressurized air source, low pressure valve, forward valve, reversing valve, relief valve, take the pressure sensor of gauge outfit, high -pressure gas source signal to be connected. The utility model has the advantages of high automation, low cost, high efficiency.
