Precautions for installation of electric eccentric hemisphere valve
Precautions for installation of electric eccentric hemisphere valve are as follows:
1. Remove the protective covers on both sides of the flange end, and flush and clean the valve when all valves are open.
2. Before installation, the whole machine shall be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the service performance), and it can be installed online only after it is qualified.
3. Before connecting with the pipeline, the residual impurities in the pipeline must be washed and cleaned (these substances may damage the valve seat and ball).
4. During installation, please do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories.
5. This type of valve shall be installed in the horizontal or vertical direction of the pipeline.
6. The pipeline near the installation point shall not sag or bear external force, and the pipeline support or support can be used to offset the deviation of the pipeline.
7. After connecting with the pipeline, please cross lock the flange connecting bolts with the specified torque.
Therefore, when installing the electric eccentric hemisphere valve, these details should be done well to ensure its good performance.
