Basic introduction of air tube head seal rubber ring for Marine permeable cap.
When Marine air pipe head, Marine air cap in the vertical position and 40 ° inclined cases into the water, and air pipe head inside the buoy can float in a flash, in contact with the sealing seat, its sealing degree can effectively prevent the water into the air/overflow pipe, delay the tank fill time. After the ship back to normal state, buoy automatic landing, freely breathe/function recovery.
The characteristics of the sealing rubber ring of the air vent cap of the ship ballast tank are described.
Supporting the breathable cap seal rubber ring by seawater, oil material corrosion of rubber materials, in - 30 ℃ ~ + 100 ℃ environment erosion is not easy to deformation, hardening and embrittlement.
