Description
Technical Field
The utility model relates to a fitting for boats and ships specifically is an air pipe head for boats and ships.
Background
The air pipe head is mainly used on various ships, is used for keeping the ventilation pipeline smooth, and enables the air pressure in a cabin to be close to the atmospheric pressure through ventilation and air suction. Meanwhile, when the ship body inclines or meets stormy waves, self-sealing can be realized, and air is prevented from entering the cabin. In the conventional method, a floater is arranged in an air inlet cavity, the floater can float on the water surface, and when the water surface rises, the floater rises to block an air vent, so that seawater is prevented from entering a cabin. In the prior art, the fixing modes of the floater are divided into two modes, one mode is soft rope traction, the other mode is that the top surface of the floater is fixed by adopting a connecting rod, and the two fixing modes have defects in the ascending process of the floater. When the soft rope is adopted for traction, the floater is easy to deviate left and right when floating upwards and is not vertical upwards, and the floater is easy to deviate from the air inlet to be blocked in the process of shaking seawater, so that the seawater enters the cabin; the top surface of the floater is fixed by the connecting rod, and the floater can deviate within a certain range due to the continuous left-right shaking of the seawater for supporting the floater to ascend, so that the connecting rod can be driven to shake left and right.

When boats and ships take place to incline or meet the stormy waves, the sea water enters into the air inlet intracavity from air inlet and drain department, and along with the rising of surface of water, the float upwards slides along the slide from the bracing piece, and the slide setting is under the gas outlet, when the float come-up to the top, alright in order to realize effectively sealing to the gas outlet. When the seawater is discharged, the seawater can be discharged along the air inlet and the water outlet simultaneously, so that the water discharging time is reduced, and the seawater can be conveniently ventilated in time.
The beneficial effects of the utility model reside in that: the sealing effect is good. The left side and the right side of the floater are provided with the sliding blocks, and the sliding blocks can slide in the sliding ways, so that the movement track of the floater is effectively limited, and the floater can only vertically upwards block the air outlet of the air inlet cavity, and the phenomenon that the air outlet cannot be effectively blocked due to the fact that the movement track of the floater deviates is avoided. The top of float is provided with the blotter, can effectively avoid float direct impact air inlet chamber's gas outlet position department, simultaneously because blotter soft materials's deformability, can more effective realization to the sealed of gas outlet. The bottom of the slideway is provided with the supporting rod, the supporting rod plays a role of supporting the floater when seawater does not enter, and the position of the supporting rod contacting with the floater is provided with the buffer cushion, so that the collision between the floater and the supporting rod can be effectively avoided, and the change of the shape of the floater is avoided. The bottom of the vent pipe is provided with a flange plate for fixing.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only intended to illustrate the structure of the present invention more clearly.
The air pipe head for the ship comprises a shell 1, wherein an air inlet cavity 2 and an air pipe 3 are arranged in the shell 1, an air inlet 4 and a water outlet 5 are arranged at the bottom of the air inlet cavity 2, the water outlet 5 is arranged below the air inlet 4, and the water outlet 5 is connected with the bottom surface of the air inlet cavity 2 through a pipeline; two opposite slide ways 6 are arranged at the top of the air inlet cavity 2, a floater 7 is arranged in each slide way 6, slide blocks 8 are arranged on the left side surface and the right side surface of each floater 7, and each slide block 8 can slide in each slide way 6; two opposite support rods 9 are arranged at the bottom of the slide 6, the support rods 9 are connected with the side wall of the air inlet cavity 2, and the distance between the two opposite support rods 9 is smaller than the diameter of the floater 7; the top of the air inlet cavity 2 is provided with an air outlet 10, the diameter of the air outlet 10 is smaller than that of the float 7, the breather pipe 3 is arranged at one side of the air inlet cavity 2, and the top of the breather pipe 3 is provided with a vent hole 11; a flange 12 is arranged at the bottom of the vent pipe 3.
