The installation process of threaded ball valves needs to follow certain steps to ensure their correct installation and good operation. The following is a detailed introduction to the installation process of threaded ball valves:
I. Preparations before Installation
Inspect the pipelines: Ensure that the pipelines before and after the ball valve are ready and that they are coaxial. The pipeline must be capable of bearing the weight of the ball valve. If the pipeline cannot be supported, an appropriate support structure should be installed on the pipeline.
Clean the pipes: Use compressed air or appropriate cleaning tools to blow the pipes before and after the ball valve clean, removing oil stains, welding slag and other impurities. This helps to reduce the wear and leakage of the valve during use.
Check the valve: Verify the marking of the ball valve to ensure it is in good condition. Open and close the valve fully several times to verify whether it works properly.
Check the valve holes: Inspect the valve holes to ensure there is no dirt. Clean the valve hole with an appropriate cleaner, as even tiny particles may damage the sealing surface of the valve seat.
Ii. Installation Process
Prepare tools and materials: Get the required installation tools and materials ready, such as wrenches, threaded sealants, etc. Pay attention to choosing the sealant suitable for the medium and material.
Apply sealant: Apply an appropriate amount of sealant to the threaded connection to enhance the sealing performance of the connection.
Connect the valve and the pipe: Tightly connect the valve and the pipe through a threaded connection method. During the tightening process, force should be applied gradually and evenly to avoid leakage or damage caused by being too tight or too loose.
Install the actuator: If the valve is equipped with an actuator (such as a pneumatic actuator), the actuator should be installed correctly in accordance with the manufacturer's instructions. Ensure that the connection between the actuator and the valve is firm and reliable, and adjust the position and Angle of the pneumatic components properly.
Iii. Inspection and Commissioning after installation
Check the connections: Ensure that all connections are firm and reliable, without any looseness or leakage.
Operation test: Operate the driver to open and close the ball valve several times to ensure that the ball valve operates smoothly without any sluggishness, and verify whether it is working properly.
Sealing performance inspection: According to the pipeline design requirements, conduct a sealing performance inspection on the flange joint surface between the pipeline and the ball valve to ensure there is no leakage.
Iv. Precautions
Avoid damage: During the installation process, do not use the actuator part of the valve as the lifting point to prevent damage to the actuator and its accessories.
Installation direction: If the ball valve is equipped with a gearbox or pneumatic driver, it should be installed upright, that is, on a horizontal pipeline, and the driving device should be located above the pipeline.
Follow the norms: Adhere to the manufacturer's installation guidelines and relevant industry norms to ensure the correctness and safety of the installation.
By following the above steps and taking precautions, the correct installation and good operation of the threaded ball valve can be ensured. During the installation process, if any problems or uncertainties are encountered, the opinions of the manufacturer or professionals should be consulted in a timely manner.
