Abstract

The invention provides a butterfly valve sealing performance testing system under a high-temperature condition. The butterfly valve sealing performance testing system comprises a heating unit, a flow control unit and a testing unit, wherein the heating unit heats the test medium to a set temperature; the flow control unit is connected between the heating unit and the testing unit and used for adjusting the flow of the test medium; the testing unit comprises a first testing pipe, a second testing pipe and a flow meter, the butterfly valve to be tested is installed between the first testing pipe and the second testing pipe, the first testing pipe is connected with the flow control unit through the first butterfly valve, a one-way valve is installed in the first testing pipe, the second testing pipe is connected with the air outlet pipe, and the second testing pipe is connected with the air outlet pipe through the second butterfly valve. And the flow meter is arranged on the second testing pipe. The flow meter is used for accurately testing the leakage amount of the test medium, so that the test result is accurate and reliable; meanwhile, the flow control unit can adjust the flow of the test medium, so that the test system can test the leakage rates of the butterfly valve corresponding to different flows and flow rates.

Description

technical field [0001] The invention relates to the technical field of valve testing, in particular to a sealing performance testing system of a butterfly valve under high temperature conditions. Background technique [0002] A valve is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of a flowing fluid medium, and a valve is a basic component in a piping system. Leakage of the valve will cause the production to fail to run normally. The sealing inspection of the valve is also called the valve leakage inspection, and the valve leakage inspection must be carried out when the valve leaves the factory. [0003] High temperature will affect the sealing performance of the seals in butterfly valves. Therefore, butterfly valves used in high-temperature environments such as high-temperature flue gas pipelines must be tested for high-temperature sealing performance before leaving the factory. After searching, there is no equipment specially des...
