After the worm gear butterfly valve is installed and put into operation, it is necessary to pay attention to the maintenance of the worm gear butterfly valve. Only by doing a good job of daily maintenance can we ensure that the worm gear butterfly valve can maintain normal and stable operation for a long time, and our production work will not be affected. GNEE Group provides you with some small suggestions for the maintenance of worm gear butterfly valves:
1. For idle valves, they should be stored in a dry, ventilated and cool place, and both ends of the valve passage should be blocked to prevent dust and impurities from entering.
2. Check the valve regularly, apply anti-rust oil on the outer surface of the valve body, and clean the dirt on the valve body in time.
3. After the valve is installed, it needs to be regularly inspected to ensure its normal and stable operation. The parts that need to be inspected are:
① Is there any wear on the sealing surface of the valve? If wear occurs, it should be repaired or replaced in time.
② Is the trapezoidal thread of the valve stem and the valve stem nut seriously worn, and is the packing outdated and ineffective? Once a problem is found, it should be replaced in time.
③ Regularly check the sealing of the valve and deal with leakage in time.
④ The valve as a whole should be intact, including the bolts on the flange and bracket, and ensure that the threads are not damaged or loose.
4. If the external environment where the valve is located is relatively harsh and easily affected by bad weather, a protective cover should be installed on the valve.
5. Keep the scale on the valve intact, accurate and clear.
6. Do not hit or knock the valve that is working in the pipeline, and do not support heavy objects.
Whether the worm gear butterfly valve can operate normally is related to whether the project can proceed smoothly, so the maintenance of the worm gear butterfly valve must be taken seriously.
