How long is the maintenance cycle of waterproof ventilation valve?

The maintenance cycle of the waterproof ventilation valve varies with the use environment and frequency, but it is usually recommended to check at least once a year. The following are some recommended maintenance steps:

1. Keep the external and active parts of the waterproof ventilation valve clean: use a brush or compressed air to remove dust, oil and other dirt on the surface and mating surface of the valve. Regularly open the flush valve and the bottom plug of the steam trap for flushing, or disassemble it for flushing, so as not to block the valve with dirt.

2. Keep the lubrication of the metal waterproof and permeable valve: for the bearing position, the meshing parts of the gear and worm gear and other cooperating parts, it is necessary to add lubricating oil regularly to reduce friction and wear. Often open, high temperature valve suitable for intervals of a week to a month refueling once.

3. Maintain the daily maintenance of the electric device: at least once a month, check whether the appearance of the electric device is clean, no dust deposits, whether the device is contaminated by soda, oil, and whether the sealing surface and points are firm and tight. Make sure that the lubrication parts are filled with oil according to regulations, and the valve nut is filled with grease. The electrical part shall be in good condition without phase failure, the automatic switch and thermal relay shall not be tripping, and the indicator light shall be displayed correctly.

4. Check whether the waterproof ventilation valve is damaged: regularly check whether the waterproof ventilation valve is damaged or scratched. If it is damaged, replace it with a new waterproof ventilation valve immediately.

5. Check tightness: Make sure that the waterproof vent valve is installed correctly and check that the seal is intact. If necessary, replace the seal or use transparent easy-peel tape to increase the tightness.

6. Check the breathing passage: regularly check whether the breathing passage is blocked, and regularly clean the passage to ensure breathability.

7. Avoid exposure to direct sunlight: Waterproof ventilation valves should avoid exposure to direct sunlight. Excessive sunlight may cause them to expand, age and fail. In the hot summer, you should consider placing shading equipment next to it to reduce the temperature and avoid direct sunlight.

In short, in order to ensure that the waterproof ventilation valve can always maintain effective protection, regular maintenance must be carried out. Through regular inspection, cleaning and maintenance, the service life of the waterproof ventilation valve can be extended and the reliability and safety of the equipment can be improved.
