Flange ball valve is a commonly used switch regulating valve, which has the advantages of simple structure, easy operation, reliable sealing, and small flow loss. It is widely used in industries such as petroleum, chemical, power, metallurgy, pharmaceuticals, and food. The structure of a flanged ball valve consists of a valve body, valve stem, valve seat, valve disc, valve cover, valve core, valve shaft, valve seat gasket, valve stem gasket, valve stem handle, etc.
1、 The working principle of flange ball valve is:
The opening and closing component is a circular sphere that can be opened or closed by rotating 90 degrees. When the valve stem handle rotates, the valve stem drives the valve core to move up and down, thereby changing the opening degree of the valve disc and controlling the flow rate of the fluid, thus achieving the purpose of regulating the flow rate.
2、 Installation requirements for flange ball valves:
1. Attention should be paid to the installation position of the valve body during installation to ensure the correct installation of the valve;
2. During installation, attention should be paid to the tightening of the valve body to ensure the correct installation of the valve;
3. During installation, attention should be paid to the flatness of the valve body to ensure the correct installation of the valve;
4. During installation, attention should be paid to the cleanliness of the valve body to ensure the correct installation of the valve;
5. Attention should be paid to the stable installation of the valve body during installation to ensure the correct installation of the valve.
3、 Maintenance and upkeep of flanged ball valves:
1. Regularly check the sealing of the valve body to ensure its normal operation;
2. Regularly check the lubrication condition of the valve body to ensure the normal operation of the valve;
3. Regularly inspect the damage of the valve body to ensure its normal operation;
4. Regularly check the cleanliness of the valve body to ensure its normal operation;
5. Regularly inspect the installation of the valve body to ensure its proper functioning.
In short, flange ball valve is a commonly used regulating valve, which has the advantages of simple structure, easy operation, reliable sealing, and small flow loss. It is widely used in industries such as petroleum, chemical, power, metallurgy, pharmaceuticals, and food. However, when using it, attention should be paid to installation specifications to ensure the correct installation of the valve, as well as regular inspection and maintenance to ensure the normal operation of the valve.
