릴리프 댐퍼{Relief damper}Relief damper

본 발명은 실내를 규정압력으로 유지시키는 릴리프 댐퍼에 관한 것으로서, 보다 상세하게는 실내의 규정압력이 변경되거나 실내와 실외의 압력차가 변하는 경우에 변경된 환경에 맞게 통풍구의 개방조건을 조정할 수 있는 릴리프 댐퍼에 관한 것이다.The present invention relates to a relief damper for maintaining a room at a specified pressure. More particularly, the present invention relates to a relief damper that can adjust opening conditions of a vent according to a changed environment when a specified pressure in a room is changed or a pressure difference between a room and an outside is changed. It is about.

일반적으로 릴리프 댐퍼는 실내를 규정압력으로 유지시킬 필요가 있는 경우에 사용되는 장치이다. 예를 들어, 릴리프 댐퍼는 클린룸(Clean room) 등에 설치되어 실내압력을 규정압력으로 유지시키고, 공기의 흐름방향을 규제하여 실외의 오염공기가 실내로 유입되는 것을 방지하는 장치이다. 즉, 실내압력이 규정압력보다 낮은 경우에는 릴리프 댐퍼의 통풍구가 폐쇄되어 실외의 부유분진이나 미생물이 실내로 유입되는 것을 방지하고, 실내압력이 규정압력보다 높은 경우에는 릴리프 댐퍼의 통풍구가 개방되어 실내의 공기를 실외로 배출시키고 실내공기의 배출로 실내압력이 규정압력으로 하강하면 통풍구는 다시 폐쇄된다.In general, a relief damper is a device used when it is necessary to maintain a room at a specified pressure. For example, the relief damper is installed in a clean room and the like to maintain the indoor pressure at the specified pressure, and regulates the flow direction of the air to prevent the outdoor polluted air from entering the room. In other words, if the indoor pressure is lower than the specified pressure, the vent of the relief damper is closed to prevent the inflow of suspended dust or microorganisms into the room. If the indoor pressure is higher than the specified pressure, the vent of the relief damper is opened. If the air is discharged to the outside and the indoor pressure drops to the specified pressure by the discharge of the indoor air, the vent is closed again.

이러한 역할을 하는 릴리프 댐퍼는 규정압력이 변경되는 경우나 실외환경의 변화로 인해 실외압력이 증가 또는 감소하여 실내와 실외의 압력차가 변하는 경우에는 그에 따라 통풍구가 개방되는 조건이 변경되어야 한다. 예를 들어, 작업환경의 변화로 인해 실내의 규정압력이 높아진 경우에는 릴리프 댐퍼의 통풍구가 개방되는 조건을 높아진 규정압력에 맞게 변경하여야 한다. 하지만, 종래 릴리프 댐퍼는 통풍구가 개방되는 조건을 변경하기가 용이하지 않아서 실내의 규정압력이 변경되는 경우나 실외압력이 변하는 경우에는 불편함이 뒤따랐다. 따라서 통풍구의 개방조건을 용이하게 변경할 수 있는 릴리프 댐퍼가 요구되었다.Relief dampers that play this role should change the conditions under which the vents are opened when the pressure difference between the indoor and outdoor areas changes due to an increase or decrease in outdoor pressure due to a change in the specified pressure or a change in the outdoor environment. For example, if the specified pressure in the room is increased due to changes in the working environment, the condition under which the ventilator opening of the relief damper is opened should be changed to meet the higher specified pressure. However, the conventional relief damper is not easy to change the conditions in which the vent opening is open, which is inconvenient when the specified pressure in the room or the outdoor pressure changes. Therefore, there is a need for a relief damper that can easily change the opening conditions of the vents.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 릴리프 댐퍼의 분해사시도이고, 도 2a는 본 발명에 따른 릴리프 댐퍼가 조립된 상태를 나타내는 사시도이고, 도 2b는 본 발명에 따른 릴리프 댐퍼가 조립된 상태를 나타내는 다른 사시도이다. 본 발명에 따른 릴리프 댐퍼는 실내를 정압으로 유지시킬 필요가 있는 룸에 설치되며, 릴리프 댐퍼의 전면은 실내를 향하고 후면은 실외를 향한다. 이러한 릴리프 댐퍼의 구성을 도 1을 참조하여 설명하면, 상기 릴리프 댐퍼는 하부에 통풍구(10)가 형성된 본체(15)와, 본체(15)의 전면에 부착되어 공기를 통과시키면서 외부에서 이물질이 유입되는 것을 방지하는 메쉬망(5)과, 본체(15)의 상측에 형성된 힌지공(17)에 고정된 힌지축(30)에 브래킷(35)에 의해 회동가능하게 결합되어 통풍구(10)를 개폐시키는 개폐판(25)과, 개폐판(25)에 부착되어 개폐판(25)이 통풍구(10)를 개방시키는 조건을 변경시키는 중량체(55)를 포함하여 구성된다.1 is an exploded perspective view of a relief damper according to the present invention, Figure 2a is a perspective view showing a state in which the relief damper is assembled according to the present invention, Figure 2b is another perspective view showing a state in which the relief damper according to the present invention is assembled. . The relief damper according to the present invention is installed in a room where it is necessary to keep the room at a constant pressure, and the front of the relief damper faces the interior and the back faces the exterior. Referring to FIG. 1, the relief damper has a main body 15 having a vent hole 10 formed at a lower portion thereof, and is attached to a front surface of the main body 15 to allow foreign matter to flow in from the outside. The mesh net 5 and the hinge shaft 30 fixed to the hinge hole 17 formed on the upper side of the main body 15 are rotatably coupled by the bracket 35 to open and close the ventilation holes 10. And a weight body 55 attached to the opening and closing plate 25 and the opening and closing plate 25 to change the conditions under which the opening and closing plate 25 opens the vent 10.

또한 본체(15)에는 통풍구(10)의 둘레를 따라 경사지지부(20)가 형성된다. 경사지지부(20)는 통풍구(10)를 폐쇄시킬 때 개폐판(25)과 경사지지부(20) 사이에 틈새가 생기지 않도록 도 1에 도시된 바와 같이 본체(15)의 바닥면에 대하여 비스듬하게 형성된다. 또한 경사지지부(20) 상에 O-링(도시되지 않음)을 부착하여 개폐판(25)이 통풍구(10)를 폐쇄시킬 때 개폐판(25)과 경사지지부(20) 사이에 틈새가 생기는 것을 이중으로 방지할 수 있다. 그리고 경사지지부(20)의 상벽(23)은 개폐판(25)이 일정각도 이상 회동하는 것을 방지한다. 즉, 개폐판(25)은 통풍구(10)를 개방시키기 위하여 회동할 때 일정각도 이상 회동하는 경우에는 개폐판(25)의 상단이 경사지지부(20)의 상벽(23)에 걸림으로써 더 이상 회동하지 않게 된다. 개폐판(25)의 상단에는 개폐판(25)의 회동을 용이하게 하는 무게추(40)가 부착된다. 무게추(40)로 인해 미세한 압력차에도 개폐판(25)이 통풍구(10)를 개방시키므로 실내를 규정압력으로 정확하게 유지할 수 있다.In addition, the main body 15 is inclined support portion 20 is formed along the circumference of the vent (10). The inclined support 20 is formed obliquely with respect to the bottom surface of the main body 15 as shown in FIG. 1 so that a gap does not occur between the opening and closing plate 25 and the inclined support 20 when closing the vent 10. do. In addition, by attaching an O-ring (not shown) on the inclined support 20, the gap between the open and close plate 25 and the inclined support 20 is generated when the open / close board 25 closes the vent 10. This can be prevented double. The upper wall 23 of the inclined support 20 prevents the opening and closing plate 25 from being rotated by a predetermined angle or more. That is, when the opening and closing plate 25 is rotated more than a predetermined angle when rotating to open the vent 10, the upper end of the opening and closing plate 25 is no longer rotated by engaging the upper wall 23 of the inclined support 20. You will not. On the upper end of the opening and closing plate 25 is attached a weight 40 to facilitate the rotation of the opening and closing plate 25. Due to the weight 40, the opening and closing plate 25 opens the vent 10 even in the minute pressure difference, it is possible to accurately maintain the room at the specified pressure.

상기 릴리프 댐퍼에서 중량체(55)와 개폐판(25)의 결합은 길이방향으로 가이드홀(50)이 형성된 가이드(45)를 개폐판(25)과 이격되도록 개폐판(25)에 부착한 후, 개폐판(25)과 가이드(45) 사이의 이격공간에 중량체(55)를 위치시키고, 가이드홀(50)을 통과하는 잠금나사(60)를 중량체(55)의 중앙부에 형성된 나사홈(57)에 나사결합으로 고정시킴으로써 이루어진다. 즉, 중량체(55)는 개폐판(25)에 부착된 가이드(45)에 결합됨으로써 간접적으로 개폐판(25)에 부착된다. 고정된 중량체(55)를 상하로 이동시킬 필요가 있는 경우에는 잠금나사(60)를 왼쪽으로 돌려서 푼 다음에 중량체(55)를 가이드홀(50)을 따라 원하는 위치로 이동시킨 후 잠금나사(60)를 오른쪽으로 돌려 조이면 중량체(55)는 그 위치에서 가이드(45)에 고정된다. 중량체(55)를 개폐판(25)에 부착하는 방법은 상기에서 기술된 방법이외에도 다양한 방법이 사용될 수 있다.Combination of the weight body 55 and the opening and closing plate 25 in the relief damper is attached to the opening and closing plate 25 so as to be spaced apart from the opening and closing plate 25, the guide 45 is formed with a guide hole 50 in the longitudinal direction Position the weight body 55 in the spaced space between the opening and closing plate 25 and the guide 45, the screw groove formed in the center of the weight body 55 with a locking screw 60 passing through the guide hole 50 By screwing it to (57). That is, the weight body 55 is indirectly attached to the opening and closing plate 25 by being coupled to the guide 45 attached to the opening and closing plate 25. If it is necessary to move the fixed weight body 55 up and down, loosen the locking screw 60 by turning it to the left, and then move the weight body 55 to the desired position along the guide hole 50, and then lock the screw. When the 60 is turned to the right, the weight 55 is fixed to the guide 45 at that position. As a method of attaching the weight body 55 to the opening and closing plate 25, various methods may be used in addition to the method described above.

이하에서는 도 3a와 도 3b에 도시된 본 발명에 따른 릴리프 댐퍼의 요부단면도를 참조하여 릴리프 댐퍼의 동작을 설명한다. 상기 릴리프 댐퍼는 실내압력이 규 정압력을 유지하고 있을 때에는 통풍구(10)를 개방하기 위해 실내공기가 개폐판(25)에 가하는 압력과 통풍구(10)를 폐쇄하기 위해 실외공기가 개폐판(25)에 가하는 압력 및 중량체(55)가 개폐판(25)에 가하는 힘이 균형을 이루기 때문에 도 3a에 도시된 바와 같이 통풍구(10)는 개폐판(25)에 의해 폐쇄되며 폐쇄된 상태가 유지된다. 하지만 실내압력이 규정압력보다 높아지는 경우에는 통풍구(10)를 개방하기 위해 실내공기가 개폐판(25)에 가하는 압력이 커지므로 상기 균형이 깨진다. 따라서 개폐판(25)은 도 3b에 도시된 바와 같이 통풍구(10)를 개방시키게 되고, 실내공기가 통풍구(10)를 통해 외부로 배출되어 높아진 실내압력이 규정압력으로 하강하면 개폐판(25)은 다시 통풍구(10)를 폐쇄한다. 이러한 과정을 반복하여 릴리프 댐퍼는 실내를 규정압력으로 유지시킨다.Hereinafter, the operation of the relief damper will be described with reference to the main cross-sectional view of the relief damper according to the present invention shown in FIGS. 3A and 3B. The relief damper is a pressure applied by the indoor air to the opening and closing plate 25 to open the vent 10 and the outdoor air to close the vent 10 when the indoor pressure maintains the prescribed pressure. Since the pressure applied to) and the force applied to the opening and closing plate 25 by the weight body 55 are balanced, as shown in FIG. 3A, the vent 10 is closed by the opening and closing plate 25, and the closed state is maintained. do. However, when the indoor pressure is higher than the prescribed pressure, the pressure applied to the opening / closing plate 25 to open the vent 10 is increased, so the balance is broken. Accordingly, the opening and closing plate 25 opens the vent 10 as shown in FIG. 3B, and when the indoor air is discharged to the outside through the vent 10, the increased indoor pressure falls to the prescribed pressure, the opening and closing plate 25. Again closes the vent 10. By repeating this process, the relief damper keeps the room at the specified pressure.

만약 실외환경의 변화로 인해 실외압력이 감소하여 실내와 실외의 압력차가 커진다면, 개폐판(25)을 폐쇄하기 위해 실외공기가 개폐판(25)에 가하는 압력이 감소하므로 개폐판(25)은 실내압력이 규정압력보다 높지 않을 때에도 통풍구(10)를 개방하게 된다. 이때에는 실외공기가 개폐판(25)에 가하는 압력이 감소된 만큼 개폐판(25)에 상하 이동가능하게 결합된 중량체(55)의 위치를 아래로 이동시켜 중량체(55)가 개폐판(25)에 가하는 힘을 증가시킨다. 따라서 개폐판(25)은 실내압력이 규정압력보다 높을 때에 통풍구(10)를 개방하게 된다.If the outdoor pressure decreases due to a change in the outdoor environment, and the pressure difference between the indoor and outdoor increases, the pressure applied to the open / close board 25 by the outdoor air to close the open / close board 25 decreases, so that the open / close board 25 is The vent 10 is opened even when the room pressure is not higher than the prescribed pressure. At this time, as the pressure applied to the open / close board 25 is reduced, the position of the weight body 55 coupled to the open / close board 25 so as to be movable up and down is reduced so that the weight 55 is open / closed plate ( Increase the force on 25). Therefore, the opening and closing plate 25 opens the vent 10 when the room pressure is higher than the prescribed pressure.

또한 작업환경변화나 생산하는 물품의 변화 등으로 인해 실내의 규정압력이 10% 정도 높아진 경우에는, 높아진 압력(즉, 10 %)만큼 개폐판(25)에 결합된 중량체(55)의 위치를 아래로 이동시켜 중량체(55)가 개폐판(25)에 가하는 힘을 증가시 킨다. 따라서 개폐판(25)은 실내압력이 변경된 규정압력보다 높을 경우에 통풍구(10)를 개방하게 되어 실내압력을 변경된 규정압력 유지시킨다. 즉, 개폐판(25)에 결합된 중량체(55)의 위치를 조정하는 간단한 조작으로 통풍구(10)가 개방되는 조건을 변경할 수 있다. 그리고 중량체(55)를 가이드홀(50)의 상단에 위치시키면 개폐판(25)은 통풍구(10)를 항상 개방시키므로 릴리프 댐퍼는 환기구로서도 이용될 수 있다.In addition, when the specified pressure in the room is increased by about 10% due to a change in the working environment or a product to be produced, the position of the weight body 55 coupled to the opening and closing plate 25 by the increased pressure (that is, 10%) is increased. By moving downward, the weight 55 increases the force exerted on the opening and closing plate 25. Accordingly, the opening and closing plate 25 opens the vent 10 when the indoor pressure is higher than the changed prescribed pressure to maintain the changed specified pressure. That is, it is possible to change the condition in which the vent opening 10 is opened by a simple operation of adjusting the position of the weight body 55 coupled to the opening and closing plate 25. When the weight body 55 is positioned at the upper end of the guide hole 50, the opening / closing plate 25 always opens the air vent 10 so that the relief damper may be used as the air vent.
