Description
Technical field
This utility model relates to a kind of New Marine air hose joint, belongs to air hose joint technique field.
Background technology
Air hose joint is as cabin indoor ventilation parts, it is ensured that the air circulation inside and outside air hose joint, exists simultaneously
Ship inclination and when running into stormy waves, can self-closed passage, prevent outside inwelling from entering cabin.In being provided with in housing for this
Aperture, is introduced outside air in air hose joint by inner orifice.For preventing sea water from pouring in down a chimney, in the bottom of inner orifice
Being provided with and can descend lower locomotivity floating drum, when cabin tilts to make water hull body enter, floating drum floating to inner orifice, passes through under buoyancy
It is arranged on the sealing ring at inner orifice to realize sealing.For increasing sealing property, existing sealing ring has steel-wire carcass in upside,
The sealing surface of sealing ring lower potion uses has flaring O-ring seal, and making sealing ring and floating drum is linear sealing.Although line is close
Envelope has preferable sealing property, but also requires that higher quality of fit.Can move up and down normally for meeting floating drum, especially exist
Under the influence of external force, floating drum can also normal locomotivity, have bigger fit clearance, this sealing between usual floating drum and support rod
Structure is only applicable to the place that angle of inclination is less, when air hose joint is with all directions submergence of ship inclination 40 °, due to
Fit clearance bigger between floating drum and support rod, just makes sealing property can not meet requirement, causes water easily to infilter in pipeline, and
Permeable phenomenon occurs, it is impossible to reach to use requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, and air hose joint tilts the direction submergence of 40 ° at each
Sealing property all can meet the New Marine air hose joint required.
This utility model is that the technical scheme reaching above-mentioned purpose is: a kind of New Marine air hose joint, including housing
And floating drum, it is characterised in that: described housing includes that middle chamber, the upper cavity on top and the bottom at middle part communicates with bottom surface pore
Lower chamber, also at least one perpendicular tract communicates with upper cavity and lower chamber in housing, and perpendicular tract is not communicated with middle chamber,
Housing is provided with inner orifice between middle chamber and upper cavity, and housing sidepiece is provided with the side opening mouth communicated with middle chamber, side opening
Being provided with protection network on Kou, housing bottom is provided with adpting flange；Sealing ring includes the outer shroud notch outside main body, main body and the end
Portion downwardly extends and the sealing ring of inside aperture center curvature, and the outer groove muzzle of sealing ring is contained at inner orifice, housing in
Between support bar is installed on dividing plate on cavity and lower chamber, support bar is set with the floating drum that can move freely, during sealing
Floating drum forms face seal with the sealing ring of sealing ring.
This utility model is set with sealing ring at the inner orifice of middle chamber and upper cavity, and to downward bottom sealing ring
Stretch and the sealing ring of inside aperture center curvature, under floating drum is in buoyancy floating to inner orifice at, make sealing ring sealed bottom
Ring forms face seal with floating drum, adds the sealing area of sealing ring and floating drum, can coordinate bigger between support rod with floating drum
Gap compensates, and can solve floating drum relatively big with the fit clearance of support rod, and cause the insecure problem of sealing.When at cabin
During inclination, make the sealing ring on sealing ring all can fit completely under each operating mode with floating drum, make air hose joint incline at each
The direction submergence sealing property of oblique 40 ° all can meet requirement.Air hose joint of the present utility model is easy for installation, venting capability
Good, boats and ships fire prevention under any working condition, insect protected performance can be fully ensured that.
