The Principle And Function Of Butterfly Valve And Installation Precautions
Apr 01, 2024| Butterfly valve is a kind of fluid control valve, its main principle is to change the flow of fluid by rotating a disc, with fast opening and closing, small size, light weight, easy to operate, etc., widely used in various pipeline systems.
The main function of the butterfly valve is to regulate the flow of the medium, which is usually used for medium flow control and truncation of the fluid medium in the pipeline. It can adjust the size of the medium flow to achieve the purpose of flow control. At the same time, the butterfly valve can also realize the cut-off of the medium to ensure the safe operation of the pipeline system.
In the installation of butterfly valves, the following matters need to be noted:
Select the appropriate butterfly valve model and specification, according to the nature of the medium and working conditions to match.
Before installation, the butterfly valve should be cleaned and inspected to ensure that its appearance and interior are free of damage and impurities.
When installing the butterfly valve, it should be operated in accordance with the installation instructions provided by the valve manufacturer. The axis of the butterfly valve should be consistent with the pipeline axis during installation, and the butterfly valve should not be stressed and deformed in the state of full opening and full closing.
When installing the butterfly valve, attention should be paid to the sealing of the valve to avoid medium leakage.
In the installation of the butterfly valve, it is also necessary to exhaust and fill the pipeline system to ensure the normal operation of the butterfly valve.
In short, when installing the butterfly valve, it is necessary to comprehensively consider the factors such as the valve model, specifications, medium nature and working conditions, and operate in accordance with the installation instructions provided by the valve manufacturer. At the same time, it is also necessary to pay attention to the tightness of the valve to ensure the safe operation of the pipeline system.
