The application provides a kind of pneumatic gas
butterfly valve radial seal test
system and test method, including gas generating device, switch valve,
gas heating device, first test
butterfly valve and
waste gas treatment device;The first test
butterfly valve is connected with main
gas pipeline, and the opening and closing or opening size of main
gas pipeline is controlled by the butterfly plate rotatable along the valve shaft, the butterfly plate is three eccentric structure, further including the
flange fixedly connected with valve body by being buckled on the outside of butterfly plate, and the gap between the
flange and butterfly plate is provided with
valve seat.Affirmative effect: the test
system generates gas by gas generating device, secondary heating and pressure regulating method to meet the strict
test requirements.Test gas can be recycled multiple times by
gas heating device and cooling device for multiple variable tests, reducing test cost and improving gas
utilization rate.
