Description

차압제연시스템의 과압배출댐퍼장치 {DAMPER APPARATUS OF OVER PRESSURE EXHAUST}DAMPER APPARATUS OF OVER PRESSURE EXHAUST}

본 발명은 각종 덕트 및 환기통로나 건축물의 특별피난계단 및 비상용승강기 또는 승강장등에 화재시 발생하는 유해가스 및 연기(이하 "에어"라 통칭함)가 피난경로에 유입되지 못하도록 하여 인명피해를 최소화할 수 있도록 한 차압제연시스템의 과압배출댐퍼장치에 관한 것이다.The present invention prevents harmful gases and smoke (hereinafter referred to as "air") generated in a fire in a special evacuation stairs, emergency lifts or platforms of various ducts and ventilation passages or buildings to prevent inflow into the evacuation path to minimize human injury. The overpressure discharge damper device of the differential pressure control system.

일반적으로 고층건축물의 특별피난계단이나 비상용승강기 및 승강장에는 급기가압을 이용한 차압제연시스템을 설치하여 피난경로를 보호하도록 하는 것이 세계적 추세이며, 국내 소방관계법규도 이러한 방식을 규정하고 있다.Generally, special evacuation stairs, emergency lifts, and platforms in high-rise buildings have a global trend to protect evacuation routes by installing differential pressure suppression systems using air pressure, and domestic firefighting laws also regulate these methods.

그러나 급기 량이 과다하면 차압이 너무 커져서 출입문을 열기 힘들어져 오히려 피난에 장애가 될 수 있으므로 적정량을 초과하는 급기 량은 배출함으로써 제연구역의 차압을 적정 수준으로 유지할 필요가 있다.However, if the air supply is excessively large, the differential pressure becomes so large that it is difficult to open the door, which may impede evacuation. Therefore, it is necessary to discharge the air supply exceeding the proper amount to maintain the differential pressure in the ventilation area at an appropriate level.

이러한 과잉급기를 배출하기 위한 한 가지 방편으로서 과압배출댐퍼를 설치 하는 방법이 있는데, 과압배출댐퍼는 다음 두 가지의 성능을 갖추어야 한다.One way to discharge such excess air supply is to install an overpressure discharge damper. The overpressure discharge damper must have the following two performances.

첫째, 개방률이 클 것: 개방률이 작으면 배출 대상 에어 량에 비해 댐퍼의 크기가 너무 커져서 설치가 곤란할 수 있다. 특히 계단실의 부속실처럼 용적이 협소한 공간에는 공간크기에 맞는 적정 크기의 댐퍼를 만들기 어렵다.First, the opening rate should be large: If the opening rate is small, the size of the damper may be too large for the amount of air to be discharged, which may make installation difficult. In particular, it is difficult to make a damper of an appropriate size in a space with a small volume, such as an attached room of a staircase.

둘째, 배출대상 에어 량에 따른 압력의 변화가 작을 것: 구역 내의 압력에 밀려 댐퍼가 열림으로써 에어가 배출될 때, 댐퍼는 초기 세팅한 압력에서 개방이 시작될 수 있지만 내부압력이 높아짐에 따라 에어를 다량 배출함으로써 구역내의 압력을 적정범위 내로 유지하는 것은 어렵다. Second, the change in pressure in accordance with the amount of air to be discharged is small: when the air is discharged by opening the damper due to the pressure in the zone, the damper may start opening at the initially set pressure, but the air may increase as the internal pressure increases. It is difficult to keep the pressure in the zone within the proper range by releasing a large amount.

현재 시판되는 댐퍼는 위의 두 가지 성능을 해결하지 못하여 제연구역의 차압을 적정범위에서 유지하는 것이 어렵기 때문에 아직까지 만족할 만한 차압제연시스템을 구축하지 못하고 있는 실정이다.Current dampers do not solve the above two performances, so it is difficult to maintain the differential pressure in the ventilation area in an appropriate range, it has not yet been able to build a satisfactory differential pressure suppression system.

본 발명은 상기와 같은 문제점을 감안하여 이를 해소하고자 발명한 것으로서, 그 목적은 가압 공간 내외부의 압력 차이에 의해 자동으로 댐퍼가 열리고 닫힘으로 실내외의 압력 차이를 항상 일정하게 유지함으로써 피난문의 개방을 원활히 하는 과압배출댐퍼장치를 제공함에 있다.The present invention has been invented to solve this problem in view of the above problems, the purpose of the damper is automatically opened and closed by the pressure difference inside and outside the pressurized space by constantly maintaining a constant pressure difference between the interior and exterior, thereby smoothly opening the evacuation door. An overpressure discharge damper device is provided.

상기 목적을 달성하기 위한 본 발명의 과제해결수단은, 내부에 설치된 격벽(13)을 중심으로 일 측에는 에어가 인입되고 배출되도록 전/후방이 개방된 에어진행부(11)가 형성되고, 타 측에는 상기 에어진행부보다 작은 단면적의 공간을 가지며 후방이 개방된 댐퍼구동부(12)를 갖는 케이스(10)와, 상기 격벽을 관통하며 에어진행부 및 댐퍼구동부의 중앙부를 가로지르도록 회전 가능하게 설치된 샤프트(14)와, 상기 에어진행부에 위치한 샤프트를 중심으로 양측에 동일한 크기의 날개(15)가 일직선이 되게 설치된 댐퍼(D)와, 상기 댐퍼구동부에 위치한 샤프트에 설치되어 후방의 개방부로 공급되는 에어에 의해 회전되는 회전판(16)과, 상기 날개 및 회전판이 설치된 샤프트의 어느 일 측 선택된 곳에 설치되어 샤프트의 회전각도에 따라 복원력이 적당하게 증가토록 함으로써 개방각도를 가압공간 내부의 압력에 대응하게 하는 탄성부재(17)와, 상기 댐퍼구동부에 회전판의 회전을 유도하도록 설치되며 상단에는 회전판의 더 이상 회전을 제어하는 걸림 턱(18a)이 형성된 회전판가이더(18)와, 상기 댐퍼구동부에 위치한 샤프트에서부터 수직으로 격벽의 상단에 이르기까지 설치된 에어차단벽(19)으로 이루어진다.The problem solving means of the present invention for achieving the above object is formed on the one side of the partition 13 is installed inside the hung part 11 is opened to the front and rear so that air is drawn in and discharged, the other side A case (10) having a damper driver (12) having a space having a smaller cross-sectional area than the recessed part and having an open rear portion, and a shaft rotatably installed to cross the center part of the leading part and the damper driver part passing through the partition wall; 14 and a damper (D) having the same size of wings (15) installed in a straight line on both sides of the shaft located in the inner leading portion, and the shaft located in the damper driver and supplied to the rear opening portion. Rotating plate 16 rotated by air and installed on any one side of the shaft in which the blade and the rotating plate is installed, the restoring force is appropriately increased according to the rotation angle of the shaft The locking member is installed to induce rotation of the rotating plate by the elastic member 17 and the damper driving unit, and a locking jaw 18a for controlling the further rotation of the rotating plate is formed at the upper end thereof. It consists of a rotary plate guider 18 and an air barrier wall 19 installed vertically from the shaft located at the damper driver to the top of the partition wall.

그리고 상기 회전판(16)이 설치된 샤프트(14)의 타 측에 무게중심부재(20)를 설치하여 된 것이며, 상기 탄성부재(17)는 케이스(10)의 격벽이나 외벽 등 고정부분과 샤프트 사이에 설치하여 고정부분을 기준으로 샤프트 회전이 복원력을 갖도록 된 것이다.The center of gravity member 20 is installed on the other side of the shaft 14 on which the rotating plate 16 is installed. The elastic member 17 is disposed between the shaft and the fixing part such as the partition wall or the outer wall of the case 10 and the shaft. Installed so that the shaft rotation with respect to the fixed portion has a restoring force.

이상과 같은 본 발명에 따른 과압배출댐퍼장치는 화재가 발생한 건축물의 내부에서 가압 공간 내외부의 압력 차이에 의해 자동으로 댐퍼가 열리고 닫힘으로 실내외의 압력 차이를 항상 일정하게 유지함으로써 피난문의 개방을 원활히 하여 인명피해를 최소화할 수 있는 효과가 있다. As the overpressure discharge damper device according to the present invention as described above, the damper is automatically opened and closed by the pressure difference inside and outside the pressurized space inside the building in which the fire occurs, thereby keeping the pressure difference between the inside and outside always constant, thereby smoothly opening the evacuation door. It has the effect of minimizing human injury.

상기 효과를 달성하기 위한 본 발명에 따른 차압제연시스템의 과압배출댐퍼장치를 첨부도면을 참조하여 상세하게 설명하면 다음과 같다.Referring to the accompanying drawings, the overpressure discharge damper device of the differential pressure elimination system according to the present invention for achieving the above described in detail as follows.

본 발명에 따른 댐퍼(D) 및 회전판(16)이 작동하기 전에는 도 1에 나타낸 바와 같이 케이스(10)의 내부 즉, 에어진행부(11) 및 댐퍼구동부(12)에서 수직상태(닫힌 상태)로 있다가 상기 댐퍼구동부(12)의 후방 압력이 전방 압력보다 일정수준 이상 높아지면 개방부(12a)를 통하여 작용하는 압력에 의해 회전판(16)이 회전을 하면서 샤프트(14)를 회전시키고 그와 동시에, 날개(15)가 회전하면서 도 2에 나타낸 바와 같이 수평상태(열린 상태)가 되어 에어진행부(11)의 전방 개방부(11b)로 에어가 배출됨으로써 압력이 저하된다.Before the damper D and the rotating plate 16 according to the present invention operate, as shown in FIG. 1, the vertical state (closed state) of the inside of the case 10, that is, the hung part 11 and the damper driver 12. If the rear pressure of the damper driver 12 is higher than the front pressure by a predetermined level or more, the rotating plate 16 rotates by the pressure acting through the opening 12a, and the shaft 14 rotates. At the same time, as the blade 15 rotates, as shown in Fig. 2, the air is discharged to the front opening portion 11b of the row portion 11, which is in a horizontal state (open state), thereby reducing the pressure.

이때 상기 댐퍼구동부(12)의 회전판(16)하부 즉 회전판(16)이 회전되는 궤적의 하부에는 회전판가이더(18)가 설치되어 있고, 또 상기 댐퍼구동부(12)에 위치한 샤프트(14)에서부터 수직으로 격벽(13)의 상단에 이르기까지는 에어차단벽(19)이 설치되어 있기 때문에 상기 댐퍼구동부(12)의 후방 개방부(12a)에 작용하는 에어 압은 회전판(16)에 미치게 되고 그에 따라 회전판(16)이 회전판가이더(18)의 상단 에 형성된 걸림 턱(18a)에까지 회전을 하게 된다.At this time, the rotary plate guide 18 is installed under the rotary plate 16 of the damper driver 12, that is, the lower part of the trajectory of the rotary plate 16, and is perpendicular to the shaft 14 located at the damper driver 12. Therefore, since the air blocking wall 19 is provided up to the upper end of the partition 13, the air pressure acting on the rear opening 12a of the damper driver 12 extends to the rotating plate 16 and accordingly the rotating plate. 16 is rotated to the locking jaw (18a) formed on the top of the rotary plate guider (18).

단 상기 회전판(16)의 회전각도(작용각도)는 90도인데, 그 이유는 회전판(16)의 회전각도가 90도를 초과하게 되면 에어진행부(11)의 샤프트(14)에 설치된 날개(15)가 도 2에 나타낸 바와 같이, 최대로 열린 상태인 수평상태를 관성에 의해 일시적으로 초과하였다가 복원되는 과정이 반복되면서 진동과 소음을 발생시키기 때문이다. However, the rotation angle (acting angle) of the rotating plate 16 is 90 degrees, because the rotation angle of the rotating plate 16 is greater than 90 degrees, the blades installed on the shaft 14 of the hanger 11 ( This is because, as shown in FIG. 2, the process of temporarily exceeding and restoring the horizontal state which is the maximum open state by inertia is repeated, generating vibration and noise.

따라서 상기 회전판(16)의 회전각도는 90도가 최대치임으로 회전판가이더(18)의 상단에 형성된 걸림 턱(18a)도 회전판(16)의 최대 회전각도인 90도에 준하도록 형성시킨다.Therefore, the rotation angle of the rotating plate 16 is 90 degrees maximum, so that the locking jaw 18a formed at the top of the rotating plate guider 18 is also formed to correspond to the maximum rotating angle of the rotating plate 16 at 90 degrees.

한편 상기 회전판(16)의 회전각도와 에어진행부(11)의 샤프트(14)에 설치된 날개(15)의 회전각도는 동일하기 때문에 댐퍼구동부(12)의 후방 개방부(12a)에 작용하는 에어 압에 따라 회전판(16)의 회전량이 결정되고 그에 따라 날개(15)의 회전각도도 결정되어 에어의 배출량을 결정하게 되는 것이다.Meanwhile, since the rotation angle of the rotor plate 16 and the rotation angle of the vane 15 installed on the shaft 14 of the hanger 11 are the same, the air acting on the rear opening 12a of the damper driver 12 is the same. The rotational amount of the rotating plate 16 is determined according to the pressure, and accordingly, the rotation angle of the vane 15 is also determined to determine the discharge of air.

그러므로 목적 공간의 내외부 차압을 항상 일정하게 유지할 수 있다.Therefore, the differential pressure inside and outside the object space can be kept constant at all times.

또 상기 날개(15) 및 회전판(16)이 설치된 샤프트(14)의 어느 일 측 선택된 곳에는 탄성부재(17)가 설치되는데, 상기 탄성부재(17)를 설치하는 이유는 샤프트(14)의 회전각도가 목적 공간 내외부의 압력 차이에 대응하도록 하기 위한 것으로서, 상기 샤프트(14)가 열림 방향으로 회전될 때에는 탄성부재(17)가 인장력을 발휘하게 되고, 상기 회전판(16)에 작용하는 에어 압이 떨어지게 되면 그 떨어진 만큼 상기 탄성부재(17)의 인장력에 의해 원 위치된다.In addition, an elastic member 17 is installed at one side of the shaft 14 in which the blade 15 and the rotating plate 16 are installed. The reason for installing the elastic member 17 is the rotation of the shaft 14. The angle is to correspond to the pressure difference inside and outside the target space. When the shaft 14 is rotated in the opening direction, the elastic member 17 exerts a tensile force, and the air pressure acting on the rotating plate 16 If it falls, the distance is in the original position by the tension of the elastic member 17.

상기 탄성부재(17)는 회전각도가 0 - 90도까지 변하는 동안 적절한 범위에서 인장력이 증가하도록 선정되는 것으로, 이러한 탄성부재로는 비틀림스프링 또는 코일스프링 등의 탄성부재 중의 어느 하나를 선택적으로 사용할 수 있다.The elastic member 17 is selected to increase the tensile force in the appropriate range while the rotation angle is changed from 0 to 90 degrees, such elastic member may be selectively used any one of the elastic member such as torsion spring or coil spring have.

그리고 상기 회전판(16)이 설치된 샤프트(14)의 타 측에는 무게중심부재(20)가 설치되는데, 상기 무게중심부재(20)를 설치하는 이유는 축에 대한 회전력에서 회전판(16)과 완전한 평형을 이루도록 하는 것이다.In addition, the center of gravity member 20 is installed on the other side of the shaft 14 on which the rotating plate 16 is installed. The reason for installing the center of gravity member 20 is that the rotating plate 16 is completely in equilibrium with the rotating plate 16. To achieve.

그럼으로써 회전판(16)에 작용하는 압력 외에는 아무 것도 회전력에 영향을 미치지 않게 된다.As a result, nothing except the pressure acting on the rotating plate 16 affects the rotational force.

단, 상기 무게중심부재(20)의 형태는 회전판(16)과 완전한 평형을 이루기만 하면 도 1 및 도 2에 나타낸 형태 외에도 다양한 형태로 설치하여 사용할 수 있다.However, the shape of the center of gravity member 20 can be installed and used in various forms in addition to the form shown in Figs.

이상과 같은 본 발명은 건축물 내부의 가압공간에서 발생하는 에어 압에 의해 자동으로 댐퍼가 열리고 닫힘으로 가압공간 내외의 압력 차이를 항상 일정하게 유지함으로써 피난문의 개방을 원활히 하여 인명피해를 최소화할 수 있는 장점이 있다.According to the present invention as described above, the damper is automatically opened and closed by the air pressure generated in the pressurized space inside the building, thereby maintaining a constant pressure difference inside and outside the pressurized space at all times, thereby smoothly opening the evacuation door and minimizing human injury. There is an advantage.
