A correctable ventilation device for marine fuel tank

Abstract

The invention discloses a rectifiable ventilation device of a ship fuel tank cabinet. The rectifiable ventilation device of the ship fuel tank cabinet comprises an air pressure balance pipe. An air guide pipe is connected to an air outlet formed in the top of the air pressure balance pipe. A connection flange is connected to the tail end of the air guide pipe. An air inlet pipe is connected to the bottom of the air pressure balance pipe. A floating cone is connected to a pipe orifice, in the air pressure balance pipe, of the air inlet pipe in a lap joint mode. Two wiring seats are connected to the top of an inner cavity of the air pressure balance pipe, and the two wiring seats are located on the two sides of the air outlet. A cable is connected to the bottom of each wiring seat. The two cables are connected with the two sides of the top of the floating cone correspondingly. Two connection seats are arranged at the bottom of the inner cavity of the air pressure balance pipe, and the two connection seats are located on the two sides of the air inlet pipe correspondingly. Through cooperation of a miniature electric telescopic rod, an adjusting plate and the floating cone, the air intake and air pressure balance effects are achieved, offtrack is avoided, airtightness between the floating cone and the air inlet pipe is improved, and the situation that sea water enters the cabinet and pollutes fuel oil is avoided.

Description

technical field [0001] The invention relates to the technical field of ship accessories, in particular to a correctable ventilation device for a ship's fuel tank. Background technique [0002] Ship, the general term for all kinds of ships. Ships are means of transportation that can sail or berth in waters for transportation or operations, and have different technical performances, equipment and structural types according to different requirements for use. A ship is a man-made means of transportation that primarily operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats, which are collectively called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming flu...

Problems solved by technology

[0003] Among them, the ship power device includes the combustion tank of the ship, and the combustion tank needs ventilation holes to realize air pressure balance and prevent seawater from pouring back. The existing fuel tank ventilation device is to achieve The effect of air intake and balanced air pressure, but this kind of floating ball structure is a movable setting, which is prone to deviation from the track, making the sealing not good, which will cause seawater to enter and pollute the fuel
