Description

Float type water tank air pipe head

Technical Field

The utility model relates to the technical field of marine air pipe heads, in particular to a pontoon type water tank air pipe head.

Background

The air pipe head is mainly applied to various ships and is used for keeping the ventilation pipeline smooth, and the air pressure in the cabin is close to the atmospheric pressure through ventilation and air suction so as to ensure that the pressure of the cabin does not exceed the design pressure of the cabin. When the ship body tilts or encounters wind waves, water flows into the air inlet, and the pontoon in the air pipe head floats rapidly under the action of buoyancy to close the ventilation pipeline, so that the water is prevented from entering the cabin; when water flows out, the pontoon falls to the original position, and the ventilation pipeline continues ventilation.

When the conventional air pipe head is used, the floating pipe is easy to deviate when floating or falling, so that the sealing effect of the air pipe head is reduced, the conventional air pipe head is internally provided with the guide post to sleeve the floating pipe on the guide post, so that deviation of the floating pipe position is avoided, however, after the conventional air pipe head is used for a long time, more friction is generated between the floating pipe and the guide post, so that the floating pipe and the guide post are worn, the service life is influenced, and when the floating pipe and the guide post are worn, the floating pipe is easy to be blocked when floating or falling, the floating pipe and the falling are inflexible, the sensitivity is reduced, and the use is influenced.
