Faults Encountered By The Breathing Valve And What To Check Common Faults Of The Breathing Valve

Faults encountered by the breathing valve and what to check Common faults of the breathing valve mainly include: air leakage, stuck, adhesion, blockage, freezing, pressure valve and vacuum valve are often open, etc. For example: 1. Air leakage: Generally caused by corrosion, hard objects scratching the contact surface between the valve and the valve disc, deformation of the valve disc or valve seat, and tilt of the valve disc guide rod. 2. Stuck: This occurs when the valve disc guide rod is skewed and the valve stem is corroded due to improper installation of the breathing valve or deformation of the oil tank. The valve seat cannot be in place when moving up and down along the guide rod, and the valve disc is stuck on the guide rod. a certain part. 3. Bonding: The chemical and physical changes occur when oil vapor, moisture, and dust and other debris deposited on the valve disc, valve seat, and guide rod are mixed together, causing the valve disc and the valve seat or guide rod to bond together. 4. Blockage: The mechanical breathing valve has not been maintained and used for a long time, causing dust, rust and other debris to be deposited in the breathing valve or breathing tube, and bees or birds building nests at the breathing valve port, etc., causing the breathing valve to be blocked. 5. Freezing: Due to temperature changes, moisture in the air condenses on the valve body, valve disc, valve seat, guide rod and other parts of the breathing valve, and then freezes, making it difficult to open the valve. In this regard, we need to conduct regular inspections to check whether there are normal opening, air leakage, stuck, adhesion, blockage, freezing, rust, etc.; check whether the sealing gasket is leaking, and replace it if found; check the valve Whether the disc can rotate flexibly and whether there is any stuck fault; check whether the valve body sealing net is frozen or clogged and whether there is dust or dirt attached to the net; check the valve disc, valve seat, guide rod, air guide spring and other metal parts If there is rust or scale, you can use kerosene to clean it.
