Flat Type Gooseneck Ventilation
Flat Type Gooseneck Ventilation can introduce fresh air into the cabin and eliminate dirty air, creating a comfortable and healthy living environment for the crew.Flat type gooseneck ventilation is mainly installed in the upper end of the ventilation pipe and ventilator on the ship's open deck to avoid rainwater falling into the cabin when the ventilator sends air into the cabin. Flat type gooseneck ventilation has the features of reasonable structure, low resistance, easy construction, wide application and good weather tightness. Flat type gooseneck ventilation is characterized by reasonable structure, low resistance, convenient construction, complete specifications, wide applicability and good weather tightness.
Overview
Notation:
The main air inlet of the gooseneck ventilator system should be able to be closed outside the premises being ventilated.
Dampers or fire dampers on gooseneck ventilators should be easily operated or maintained.
Gooseneck ventilator through the truss through the cabin should meet the specification requirements.
Small angle elbows should be used on the pipe, and the spacing between two elbows is generally not less than 5 times of the pipe diameter.
When the gooseneck ventilating tube is spent on the pipe, in order to ensure the circulation of air flow, there should be a certain inclination along the direction of air flow.
According to the requirements of the service area of the ventilation pipe, determine the distribution form of the branch pipe, and add a regulator door at the appropriate location.
Gooseneck ventilator road should generally be arranged under the main cable and related pipe systems, but also consider the arrangement of neighboring pipe systems, and to ensure that the spacing requirements of each other.
