Description

[0001] The present invention relates to a valve for an air conditioning duct of a ship,

The present invention relates to a valve for an air conditioning duct of a ship, and more particularly, to a valve for an air conditioning duct of a ship, more particularly, to a valve for air conditioning ducts mounted on a ship without airtight ducts having cross- The present invention relates to a valve for an air conditioning duct of a ship.

In general, air conditioning refers to maintaining the air condition of a certain place in the best condition for a person or an article in the room, and is a function of the air conditioner's temperature and its distribution state, the humidity and distribution state of air, The type of material contained in the air, the amount (cleanliness), and the state of air flow (air flow).

Where air conditioning is required as described above, it is necessary to make a pleasant environment such as an office, a house, a department store, a movie theater, a factory, a research institute, a warehouse, and a computer room, or to maintain the most appropriate indoor condition The air conditioning system is divided into a central system and a private system.

Generally, when a large-sized ship is dried, a large number of long pipes and air ducts are installed.

In particular, air ducts are used for air conditioning in residential areas by introducing fresh air to each cabin, machinery room, and engine room, which are respectively partitioned in accomodation of a ship, to cool the heat generated from various facilities It can be used as an application.

Such a conventional air duct for air conditioning of a ship is constituted by a rectangular duct pipe as shown in the open utility model No. 20-2012-0001017 (Feb. 13, 2012). Referring to FIG. 1, a circular valve is used for opening and closing between compartments In order to connect the rectangular duct pipe (1) to the circular valve, there must be a separate intermediate connection (2) that can be converted from square to circular and assembled. As a result, .

This problem has become a very vulnerable problem for special ships such as submarines where quietness is a top priority.

In addition, since the special vessels such as the submarine are designed to have a very narrow space, the square duct pipe 1 and the valve are moved in the rectangular duct pipe 1 as the bolt fastening portions with the intermediate connecting hole 2 are increased. There was a danger of leakage of fluid, difficulty in assembling and difficulty in maintenance, and a large volume of space was occupied by the valve and the intermediate connector 2 having different sectional shapes from the rectangular duct pipe 1.

Therefore, the present invention can be connected to a square duct pipe for air conditioning of a ship without an intermediate connector, thereby facilitating assembly inconvenience and maintenance, preventing fluid leakage, and having a relatively small volume of space. It is an object of the present invention to provide a valve for an air conditioning duct of a ship in which installation on a special ship is easy and noise caused by fluid resistance and vortex due to fluid flow is reduced.

According to the present invention, a valve for air-conditioning duct of a ship is formed of a square tube body having the same cross-sectional size as a square duct pipe for air-conditioning, and the front and rear ends communicating with each other are bent outwardly, A rectangular disk door coupled to the inside of the valve housing by a rotation shaft to rotate the rotation shaft about the axis to intermit the flow of the fluid passing through the valve housing, And opening / closing means provided on an outer surface of the valve housing for operating opening and closing of the valve housing by rotating the rectangular disk door.

At this time, the quadrangular disk door according to the present invention is formed on the inner surface of the valve housing, and when the disk door closes the inside of the valve housing, the disk door is rotated with a predetermined angle or more And a stopper interlocked with the stopper.

In addition, the disc door according to the present invention may have rounded corners.

Also, the opening / closing means according to the present invention may be constituted by a rotary lever connected at right angles to the rotary shaft of the disc door, or connected to the rotary shaft of the disc door, so that a plurality of gears are meshed with each other, And a handle connected to the gear box and perpendicular to the rotational axis of the disc door.

In addition, the opening / closing means according to the present invention can form a display unit for confirming the opening / closing degree of the disk door.

And a vortex suppression brush for reducing the flow noise of the fluid flowing in the valve housing to either the periphery of the disc door or the periphery of the stopper according to the present invention.

According to the present invention, a valve for an air conditioning duct of a ship has the following effects.

First, the valve housing is formed in a square shape in the same shape as a rectangular duct pipe provided in the air conditioning system of a ship, and a quadrangular disk door for controlling the flow of fluid inside the valve housing is provided, It is possible to connect to the square duct pipe directly without an intermediate connection to connect with the pipe, thereby facilitating assembly inconvenience and maintenance as in the prior art, and preventing leakage of the fluid.

Second, since the valve housing is formed in a square shape in the same shape as the rectangular duct pipe provided in the air conditioning system of the ship, and a rectangular disk door for controlling the flow of the fluid inside the valve housing is provided, Since it has a space volume, it is easy to install on a special ship such as a submarine.

Third, there is provided a vortex suppression brush that suppresses vortex due to the flow of fluid around the quadrangular disk door, thereby reducing the noise generated by vortex caused by fluid flow.
