So that indoor air is ventilated.

그러나, 상기한 바와 같은 종래의 공기 환기 시스템은 환기배기부에 구비되는 배기밸브가 환기제어부의 제어에 따라 개폐동작되게 구성되어 있어 센서의 오류 또는 구동장치의 오류가 발생하게 되면, 배기밸브의 개방이 명확하게 이루어지지 않고 잘 닫히지 않게 되는 문제점이 있었다.However, in the conventional air ventilation system as described above, the exhaust valve provided in the ventilation vent portion is configured to be opened and closed under the control of the ventilation control portion, so that if a sensor error or an error in the driving device occurs, There is a problem in that it is not clear and does not close well.

또한, 종래의 공기 환기 시스템은 배기밸브가 구비되는 밸브덕트가 용접에 의하여 형성되어 기밀이 완벽하게 유지되지 않는 문제점이 있었다,Also, in the conventional air ventilation system, there is a problem that the airtightness is not maintained perfectly because the valve duct having the exhaust valve is formed by welding.

That is, the embodiments are to be construed as being variously embodied and having various forms, so that the scope of the present invention should be understood to include equivalents capable of realizing technical ideas. Also, the purpose or effect of the present invention should not be construed as limiting the scope of the present invention, since it does not mean that a specific embodiment should include all or only such effect.

즉, 본 발명은 환기흡입부와 환기배기부, 배기팬 및 환기제어부로 구성되는 공기 환기 시스템의 환기배기관에 배기압에 의하여 개방되고 자중에 의하여 닫힘되는 수직형 중력 개폐배기밸브를 구비한 것이다.That is, the present invention is provided with a vertical gravity opening and closing exhaust valve which is opened by exhaust pressure and closed by its own weight to a ventilation exhaust pipe of an air ventilation system composed of a ventilation suction portion, a ventilation exhaust portion, an exhaust fan and a ventilation control portion.

상기 밸브덕트(100)는 원통형상으로 이루어지며 상하 모서리마다 실리콘(101)결속형성된다.The valve duct 100 has a cylindrical shape, and silicon 101 is bonded to the valve duct 100 at the upper and lower corners thereof.

상기 밸브패킹(124)은 상기 밸브판(120)의 테두리에 구비된다.The valve packing (124) is provided at an edge of the valve plate (120).

또한, 상기 밸브패킹(124)의 끝단은 그 단면이 입술 모양으로 형성되는 립밀착부(125)를 더 포함하여 상기 밸브판(120)과 결합될때 충격흡수 및 밀착력을 높여준다.Further, the end of the valve packing 124 further includes a lip contact portion 125 having a lip-like cross-section, thereby enhancing impact absorption and adhesion when coupled with the valve plate 120.

또한, 상기 밸브패킹(124)의 끝단은 주름으로 형성되어 상기 밸브판(120)에 결합될때 충격흡수 및 밀착력을 높여준다.In addition, the end of the valve packing 124 is formed of corrugation to increase shock absorption and adhesion when the valve packing 120 is coupled to the valve plate 120.

또한, 상기 밸브판(120)이 회전닫힘되게 밸브슬라이드봉(121)의 외면에 상기 스타팅스프링(122)과 같은 회전 방향으로 형성되는 회전나선홈(121a)을 형성한다.In addition, the valve plate 120 is rotated and closed to form a rotating spiral groove 121a formed on the outer surface of the valve slide rod 121 in the same rotating direction as the starting spring 122.

따라서, 본 발명의 실시 예를 따른 밀폐 역풍 방지 댐퍼는 다음과 같은 작동효과가 있다.Therefore, the closed back-flow preventing damper according to the embodiment of the present invention has the following operation effect.

배기압에 의하여 개방되고 자중에 의하여 닫힘되는 수직형 중력 개폐배기밸브를 구비함으로써 밸브의 동작이 동력에 의하지 않고 명확하게 동작되는 효과를 갖는다. The vertical gravity opening and closing exhaust valve which is opened by the exhaust pressure and closed by the self weight is provided, so that the operation of the valve is clearly operated without power.

또한, 밸브덕트(100)를 실리콘(101)결속되게 형성함으로써 기밀성과 진동이 감쇄되는 효과를 갖는다.Further, by forming the valve duct 100 to be bonded to the silicon 101, airtightness and vibration are attenuated.

또한, 밸브슬라이드봉(121)의 외면에 회전나선홈(121a)을 형성함으로써 밸브판(120)이 회전닫힘되면서 공기를 외부로 원심배출시켜 밸브판(120)의 자중 닫힘이 원활하게 이루어지는 효과를 갖는다.In addition, by forming the rotating spiral groove 121a on the outer surface of the valve slide rod 121, the valve plate 120 is rotated and closed, and the air is discharged to the outside by centrifugal force to smoothly close the self-weight of the valve plate 120 .

또한, 밸브판(120)의 안쪽면에 원심블레이드(126)를 돌출형성함으로써 밸브판(120)이 회전닫힘 또는 열림 되면서 공기를 외부로 원심배출시켜 밸브판(120)의 자중 닫힘 또는 열림이 원활하게 이루어지는 효과를 갖는다.The centrifugal blade 126 is protruded from the inner surface of the valve plate 120 so that the valve plate 120 is rotated or opened to centrifugally discharge the air to the outside so that the self- .

또한, 상기 밸브패킹(124)의 끝단이 입술모양의 립밀착부(125)가 형성되면 상기 밸브판(120)과 결합될때 충격흡수 및 밀착력을 높여준다. 예컨데, 상기 립밀착부(125)는 입술부분이 밸브판(120)과 마주할때 벌어지면서 충격을 흡수하며 밀착되어 공기가 세어나가지 않게 틈을 막는 효과를 갖는다.Further, when the end of the valve packing 124 is formed with the lips-like lip portion 125, the shock absorption and adhesion can be enhanced when the valve lip 124 is engaged with the valve plate 120. For example, the lip contact part 125 has an effect of blocking the gap so that air does not come in contact with the lip part when the lip part is opened when it faces the valve plate 120 to absorb the impact.
