Description

{DAMPER APPARATUS WITH DAMPER FOR DUCT AND FIRE DAMPER}

More particularly, the present invention relates to a composite damper airtight integrated damper, and more particularly, to a damper having a damper for damaging ducts and a damper for damages caused by a fire damper, Time and cost required for installing a damper for a duct and a damper for adjusting a duct to control the damper.

Generally, when a fire occurs in a building, a signal is detected by a fire detector. When such a signal is received, a water spray fire extinguishing system, such as a sprinkler installed along the ceiling, emits fine, uniform water with a certain amount of fog Cover the combustion surface in the protective space and suppress the fire.

However, since water spray fire extinguishing equipment can not be used for dangerous materials which are difficult to extinguish by water or electrical insulators such as high-voltage electrical equipment, fire extinguishing equipment that extinguishes the fire by releasing extinguishing chemicals by the pressure of pressurized gas is used .

However, since the fire extinguishing system is required to release the fire extinguishing agent at a high pressure due to the nature of the fire extinguishing agent, the pressure inside the enclosed space of the fire extinguishing zone may instantaneously increase excessively, And an overpressure outlet for discharging the pressure to the outside is provided on the wall.

The conventional overpressure discharge port has a rectangular shape with a predetermined width and a plurality of blades connected by a link member so as to be rotatable are provided inside the frame. The blades are rotated by receiving power from a driving source such as a motor And the overpressure outlet is opened or blocked.

However, in such a conventional overpressure outlet, there is a problem in that the opening and closing operation of the blade is difficult when the driving source is not provided, so that the opening and blocking can not be performed in a timely manner. There is a problem in that a separate power source is required and control of overpressure discharge is very troublesome.

Particularly, when the fire suppression by the extinguishing agent fails, when the power is not supplied to the driving source in the state where the fire is continuously proceeding, the closed state of the blade is not maintained and the overpressure outlet is not securely blocked, Pressure air outlet is easily opened when the air and gas inside the protection zone are heated and the high pressure is generated, the oxygen is re-supplied from the outside to the room through the over-pressure outlet to raise the fire, There is a problem that the risk is increased because the fire escapes to the outside.

In order to solve the above problems, an overpressure outlet has been developed. The overpressure outlet according to the related art has a coupling piece to be coupled to a back surface of a vertical plate of a blocking plate formed on the uppermost side, A second separator fixed to the first separator is connected to the first separator through soldering, and the first separator is fixed to the second separator. And a fixing piece which is provided on one side of the back surface of the bending plate of the remaining blocking plate to separate the first and second separating pieces by melting the solder during the progress of the fire so as to fix the fixing bar rotating downward about the rotation axis .

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-1487899 (published on Feb. 02, 2015, entitled "Overpressure Exhaust with Fire Damper Function").

In this embodiment, since the duct 32 and the fire panel 34 are installed in one frame 10 at the same time, a duct damper for controlling the blowing amount, a case in which the fire damper is manufactured as a separate product and installed in one duct The blades 32 and the fire damper are installed in one frame 10 to reduce the size of the damper device.

Since the blades 32 and the fire damper are installed in one frame 10, the material cost can be reduced as compared with the case where the two frames 10 are provided, and the construction method for installing the damper device in the duct can be simplified Therefore, it is possible to save space, time and cost required for damper device construction.

The blade 32 includes a first panel 32a that rotates in one direction of the frame 10 when the plurality of blades 32 is opened by the operation of the first interlocking portion 50 and opens the flow path, And a second panel 32b which rotates in the other direction of the frame 10 when the plurality of blades 32 is opened by the operation of the first interlocking portion 50 and opens the flow path.

Since the first panel 32a and the second panel 32b are alternately arranged and driven by the blade 32 of the present embodiment, the first and second panels 32a and 32b are driven by the operation of the first interlocking portion 50, The airbag 32b is rotated in the other direction to perform the opening operation, so that the air having passed through the blade can be prevented from eccentrically moving in a direction in which the blade 32 is inclined.

In this embodiment, since the first panel 32a and the second panel 32b, which are opened to be arranged in different directions, are alternately arranged, air having passed through the blades 32 is discharged toward the center of the duct, So that it is possible to prevent the load from being concentrated by the discharged air into a part of the duct.

The first interlocking portion 50 includes a first link 52 which is provided on the rotation axis of the first panel 32a and extends in one direction of the frame 10 and a second link 52 which is provided on the rotation axis of the second panel 32b A second link 54 extending in the other direction of the frame 10 so as to be disposed in a direction opposite to the first link 52 and a second link 54 extending in the other direction of the frame 10 when the first link 52 is rotated in one direction, A link 56 connecting the first link 52 and the end of the second link 54 to rotate the first link 52 in the opposite direction and a first link 52 to rotate the first link 52 simultaneously, And an actuating bar 58 connecting the ends of the actuating bar 58.

Accordingly, when power is supplied from a driving unit such as a motor connected to the operation bar 58, the operation bar 58 is moved to one side or the other side so that the first link 52 is rotated in one direction and the second link 54 The first panel 32a is rotated to one side and the second panel 32b is rotated to the other side to perform the opening operation or the closing operation.

The second interlocking portion 70 includes a link member 72 provided on the rotation axis of the plurality of fire panels 34 and a plurality of link members 72 so that the plurality of link members 72 are simultaneously rotated in the same direction. And an interlocking bar (74) connecting them.

Accordingly, when power is supplied from the driving unit and the interlocking bar 74 is moved to one side or the other side, the plurality of link members 72 are simultaneously rotated to one side or the other side, thereby rotating the plurality of fire panels 34 in the same direction, Operation is performed.

Since the width of the fire panel 34 is narrower than that of the first panel 32a and the second panel 32b, the space required when the fire panel 34 is opened is smaller than the width of the blades 32 Therefore, the interval between the fire panel 34 and the blade 32 can be relatively narrowed, and the frame 10 can be further downsized.

Since the both ends of the fire panel 34 are formed to be bent in different directions, when the fire panel 34 is closed, the bent portions formed at the ends of the other fire panels 34 disposed adjacent to each other, And are brought into close contact with each other.

Therefore, when the fire is generated, the open state of the open holding portion 80 is released. When the fire panel 34 is closed by the operation of the closing portion 86, the bent portions formed at both ends of the fire panel 34 are inclined The flame or noxious gas is prevented from being supplied along the ducts due to the loss of the flame or the noxious gas at the interval between the fire panels 34.

The open holding portion 80 according to the present embodiment includes a wire member 82 provided between one side of the flame panel and the frame 10 so as to maintain the flame panel in a rotated state to be opened, And a fuse member 84 that is broken when the temperature inside the frame 10 rises above the set temperature to cut the wire member 82. [

Since the closing portion 86 of the present embodiment includes the elastic member 86a provided between the other side of the flame panel and the frame 10 so as to maintain the rotated state so as to close the flame panel and provide an elastic force, The flame panel is pulled by the member and is opened in a rotated state. At this time, the elastic member 86a is pulled by the flame panel to be in an expanded state.

When the temperature of the duct and frame 10 rises above a predetermined value at the time of fire occurrence, the fuse member 84 is broken and the wire member 82 is cut, so that the expanded elastic member 86a is restored to its original state, And is rotated and closed.

Accordingly, it is possible to prevent flame or noxious gas from being supplied along the ducts formed by the duct and frame 10 when a fire occurs.

Accordingly, it is possible to reduce the space in which the duct damper and the fire damper are installed, the space for installing the duct damper and the damper for blocking or adjusting the blowing amount, It is possible to provide a damper with a combined fire-fighting airtight structure that can save time and cost.
