How many mounting flanges are required for the pneumatic two-way valve distribution box? 5. The noise of butterfly valve is divided into cavitation and noise, which are the two major public hazards of butterfly valve in controlling high-pressure differential fluid. The noise on the butterfly valve is the main pollution source in petrochemical production. In addition to the butterfly valve with low noise structure, changing the operating conditions of the valve is the fundamental method to eliminate or reduce cavitation and noise.
、 At the same time, the butterfly valve controls the current flowing through it accordingly, and uses the principle of increasing the current passing area to better control the current passing through. In this process, the resistance is relatively small, so the energy saving effect is achieved. Thus, this small current plays a corresponding role in ensuring the personal safety of users. In order to consolidate the safety protection, butterfly valves are more equipped with electrostatic devices and important structures to prevent fire. With its good design concept, butterfly valves can better avoid the hidden dangers in use, which can ensure the safety problems in use.
