1. working principle is:
The opening and closing piece is a round sphere, which can be opened or closed by rotating 90 °. 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 flap and controlling the flow of fluid, so as to achieve the purpose of adjusting the flow.
2. installation requirements:
1. Pay attention to the installation position of the valve body during installation to ensure the correct installation of the valve;
2. When installing, pay attention to the installation and fastening of the valve body to ensure the correct installation of the valve;
3. When installing, pay attention to the smooth installation of the valve body to ensure the correct installation of the valve;
4. When installing, pay attention to the installation and cleaning of the valve body to ensure the correct installation of the valve;
5. When installing, pay attention to the stable installation of the valve body to ensure the correct installation of the valve.
3. flange ball valve maintenance:
1. Regularly check the sealing of the valve body to ensure the normal operation of the valve;
2. Regularly check the lubrication of the valve body to ensure the normal operation of the valve;
3. Regularly check the damage of the valve body to ensure the normal operation of the valve;
4. Regularly check the cleanliness of the valve body to ensure the normal operation of the valve;
5. Regularly check the installation of the valve body to ensure the normal operation of the valve.
In short, flanged ball valve is a commonly used regulating valve. It has the advantages of simple structure, convenient operation, reliable sealing, and low flow loss. It is widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical, food and other industries, but in use At that time, attention should be paid to the 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.
