The study of the built-in electric butterfly valve of the height valve has reference to the ordinary butterfly valve. The general study uses the performance test method of the ordinary electric butterfly valve as a reference, and measures the load displacement curve and dynamic stiffness loading frequency curve of the built-in electric butterfly valve of the height valve and the ordinary electric butterfly valve of the external height valve. Through the comparative analysis of the research results, the following conclusions are drawn:
(1) Since the change trend of the performance curves of the two electric butterfly valves is consistent and consistent with the actual driving situation, it is feasible to conduct performance test on the built-in electric butterfly valve of the height valve by referring to the performance test method of the ordinary electric butterfly valve. It can be seen that the performance test method of the built-in electric butterfly valve of the height valve is consistent with that of the ordinary electric butterfly valve;
(2) Since the height valve is set inside the electric butterfly valve, the vent cannot be closed. The load displacement curve of the electric butterfly valve inside the height valve is not the pressure transformation curve like the ordinary electric butterfly valve. However, the performance test method of the built-in electric butterfly valve of the height valve is closer to the actual situation of driving, and the test results obtained are more reliable;
(3) In view of the rationality of the above performance test research methods, the research on other test methods of the built-in electric butterfly valve of the height valve, such as stroke test, blasting test, fatigue test, etc., can use the above research methods for reference.
