Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to a microbubble exhaust valve. Background Technology

[0002] Microbubble venting valves use an internal filter to gradually remove tiny air bubbles from circulating water, reducing noise caused by free air bubbles in the circulation system and preventing flow rate fluctuations caused by free air bubble activity. They are particularly effective for systems with low static pressure and locations where bubbles are easily generated due to heating. Existing microbubble venting valves have low venting efficiency when dealing with tiny air bubbles or high-velocity fluids. Utility Model Content
