Valve fire-proof type test device

The invention relates to a valve fire-proof type test device. Flowing water with corresponding pressure needed for a type test and provided by a constant pressure source is conveyed to a valve to be tested. A nozzle adjusting mechanism in a furnace body adjusts the relative position of a nozzle outlet and a valve to be tested, the valve to be tested can be heated by high-temperature burning evenly, and the requirements for high-temperature burning temperatures of valves to be tested with different model numbers can be met. A spraying system directly carries out spraying cooling on the high-temperature valve to be tested in the furnace body, and the purpose of quick cooling is achieved. Test conditions needed by type tests of valves with different specifications are met, the test conditions are kept even and stable all the time, and accordingly testing results of the type tests are accurate and reliable.
