    This standard CB/T295-2000 marine mushroom ventilator is suitable for the design, manufacture and acceptance of ventilators for installation on the open deck of marine vessels.

    Marine mushroom ventilator - the form of marine mushroom ventilating cap is mainly divided into:

    Marine C-type external opening and closing with axial fan ventilator, mushroom vent head, mushroom ventilator

     

    Type Name Nominal diameter
    A-TYPE Internal opening and closing ventilator DN150-DN350
    B-TYPE External opening and closing ventilator

     

    DN250-DN1400

    C-TYPE External opening and closing with axial fan ventilator
    D-TYPE Fixed ventilator

     

     

    Technical agreement on marine CB/T295-2000 marine mushroom ventilator-marine mushroom ventilating cap:

    Marine C-type external opening and closing with axial fan ventilator, mushroom vent head, mushroom ventilator
    1. Marine ventilator - The surface of the marine ventilating cylinder should be smooth and smooth without sharp edges, distortion and skew.
    2. The diameter deviation of the air cylinder and the hood of the marine ventilator is ±3mm, and the deviation of the verticality is 2/h1000 (h is the height of the ventilating cylinder)
    3. The welding surface of the marine mushroom-shaped ventilating head shall be free from cracks, slag inclusions, burn through, and unfused defects.
    4. The weathertight cover of the marine mushroom-shaped ventilator should be flexible, and the active part should be coated with neutral grease.
    5. The internal and external surfaces of the steel parts of the marine mushroom ventilating cap shall be derusted to the Sa2 or St2 level specified in GB/T8923, and then the second antirust primer.

     

    Test method for CB/T295-2000 marine marine mushroom ventilator-marine mushroom ventilating cap:

    Marine C-type external opening and closing with axial fan ventilator, mushroom vent head, mushroom ventilator
    1. Flushing experiment of marine mushroom-shaped ventilator:
    Use a nozzle with a diameter of not less than 12.5, the water pressure is not less than 0.25Mpa, and then flush with the ventilator not exceeding 1.5mm. The flushing time is 3min. The result should be consistent with the "waterless beads in all parts, the sealing packing is in contact with the air cylinder. The width of the indentation is not less than 0.5t (t is the thickness of the cylinder body).

    2. Imprint experiment of marine mushroom-shaped ventilator:
    At the weathertight sealing packing, evenly apply white powder, close the weathertight cover, and then open it to check the width of the indentation of the sealing packing in contact with the edge of the air cylinder. The result should meet the requirements of 4.7.

    3. Appearance inspection of marine mushroom ventilator:
    The visual inspection was carried out by visual inspection, and the results were to comply with the standards.

    4. Dimensional inspection of marine mushroom ventilator:
    The gauge is used to check the diameter of the air duct and the hood, and the result should meet the requirements of 4.3.

     

    Marine ventilator - mushroom ventilator is usually marked as:

    Marine C-type external opening and closing with axial fan ventilator, mushroom vent head, mushroom ventilator
