The top of head, including shell, the shell is equipped with shell cover, and the air inlet that the shell side is equipped with is threaded with outer cover, institute
The junction for stating air inlet and outer cover that shell side is equipped with is equipped with flame screen, and the bottom end of the shell is installed with connection
The inside of flange, the shell is installed with refluence plate, and the bottom end for flowing backwards plate is threaded with bolt, the bolt
Floating plate is socketed on screw rod, the bottom end of the floating plate is fixed with the corresponding small-sized floating block in two positions, the top for flowing backwards plate
End and the screw rod corresponding position of bolt offer air hole, and the two bottom sides of the inner walls are equipped with sliding slot, described in two
Sliding block is slidably connected in sliding slot, and filter screen, the equal spiral shell in bottom end of two sliding slots are installed between two sliding blocks
Line is connected with screw.
Wherein, the filter screen is internally provided with activated carbon.
Wherein, spring ring is socketed on the screw rod of the bolt, the diameter of the spring ring is slightly smaller than the cylinder of floating plate
Diameter.
Wherein, the protruding end of the floating plate is equipped with sealing ring.
Preferably, the flame screen is the double-deck reticular structure.
Compared with prior art, the utility model has the advantages that：The utility model by equipped with connection method
Orchid can make air pipe head more secured with piping connection, avoid loosening because of the impact of seawater；By equipped with floating plate
It can reach good leakproofness with gasket, it is effective that seawater is prevented to enter inside air pipe head；Pass through the spring ring of setting
Good shockproof effect can be played, prevents seawater from occurring to break floating plate with tube head；It can be effective by the flame screen of setting
The effect for playing fire-proof；The impurity that can be effectively filtered air in pipeline by the filter screen of setting, makes in cabin
Air is more pure and fresh.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-2, the top of a kind of ship air pipe head, including shell 1, shell 1 is equipped with shell cover 2, shell 1 one
The air inlet that side is equipped with is threaded with outer cover 6, and the junction of the air inlet that 1 side of shell is equipped with and outer cover 6 is equipped with fire prevention
The bottom end of net 7, shell 1 is installed with connecting flange 8, and the inside of shell 1, which is installed with, flows backwards plate 3, flows backwards the bottom end of plate 3
It is threaded with bolt 5, is socketed with floating plate 4 on the screw rod of bolt 5, it is corresponding small that the bottom end of floating plate 4 is fixed with two positions
Type floating block 15, the top for flowing backwards plate 3 and the screw rod corresponding position of bolt 5 offer air hole 10, the bottom two of 1 inner wall of shell
Side is equipped with sliding slot 12, slidably connects sliding block 13 in two sliding slots 12, is installed with filter screen 9 between two sliding blocks 13, and two
The bottom end of a sliding slot 12 is threaded with screw 16.
The filter screen 9 is internally provided with activated carbon, can adsorb the impurity in air, plays purification air effect.
Spring ring 11 is socketed on the screw rod of the bolt 5, the diameter of spring ring 11 is slightly smaller than the straight of the cylinder of floating plate 4
Diameter prevents seawater from occurring to break floating plate 4 with tube head, plays good shockproof effect.
