Application of air vent head

The air vent head is mainly used in all kinds of ships, and has the following functions:

 

1. Keep the ventilation pipe unblocked: the air vent head can make the air pressure in the cabin close to atmospheric pressure, prevent the pressure in the cabin from being too high or too low, and ensure that the cabin pressure does not exceed its own design pressure.

2. Prevent water from entering the cabin: When the hull tilts or encounters wind and waves causing water to flow into the air inlet, the floating ball in the air vent head will float quickly and fit the seal ring under the action of buoyancy, thus closing the ventilation pipe and preventing water from entering the cabin; When the water flows out, the float drops to the original position, and the ventilation pipe can continue to remain unimpeded.

 

In addition, different types of air vent heads may have some special designs and functions. For example, the embedded air vent head is installed with the bulkhead embedded, which can save installation space and reduce the bulge of the ship channel, which is both beautiful and practical. The diameter of the breathable inner pipe is also equipped with a removable air purification device, which can purify the air and is easy to clean and replace. Marine cap air pipe supports the shield by setting the support column and support ring, and uses the calibration support block to clamp the fixing nut to prevent the rotation of the shield, reducing the strength of the fixing bolt and the strength of the shield.

 

The specific application of the air vent head will vary according to the type of vessel, use and design requirements. In actual use, it needs to be selected, installed and maintained according to relevant specifications and standards to ensure its normal operation and reliability.
