Maintenance of worm gear butterfly valve
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 if we do a good job in daily maintenance, we can ensure that worm gear butterfly valves works normally and stably for a long time, and our production work will not be affected. This article will introduce how to maintain the worm gear butterfly valve?
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. No dust and impurities are allowed in it.
2. Check the valve regularly, apply antirust oil on the external surface of the valve, and clean the dirt on the valve body in time.
3. After the installation, the valve should be maintained regularly to ensure it can works normally and stably. The parts to be overhauled include:
① Check whether the sealing surface of the valve is worn or not. If there is wear, it should be repaired or replaced in time.
② Check the trapezoidal thread of the valve rod and the valve rod nut is seriously worn or not and check whether the packing is out of date and invalid. Once any problem is found, replace it as necessary.
③ Check the tightness of the valve regularly and if any leakage is found, it should be handled in time.
④ The whole valve shall be intact, including the bolts on the flange and bracket, and ensure that the thread is not damaged or loose.
4. If the external environment where the valve is located is relatively harsh and vulnerable to severe weather, the valve shall be installed with a protective cover.
5. Keep the scale on the valve is completely, accurately and clearly to read.
6. Do not strike the valve which is working in the pipeline or allow the valve to support heavy objects.
Whe ther the worm gear butterfly valve can work normally or not is related to the smooth progress of our project, so we must pay attention to the maintenance of the worm gear butterfly valve.
