우선, 화재가 발생되지 않은 상태에서는 상기 스프링클러(5)의 분사노즐(5b)이 밀폐된 상태를 유지함으로, 도 7에 도시한 바와 같이, 상기 급수관(5a)을 통해 공급된 고압의 물이 상기 보조급수관(15)을 통해 제2 챔버(11b)로 공급되어 피스톤(12)을 제1 챔버(11a)쪽으로 가압한다.First, in a state in which no fire occurs, the spray nozzle 5b of the sprinkler 5 maintains a sealed state, so that, as shown in FIG. 7 , the high-pressure water supplied through the water supply pipe 5a is It is supplied to the second chamber 11b through the auxiliary water supply pipe 15 to press the piston 12 toward the first chamber 11a.

따라서, 상기 탄성부재(14)가 압축되면서 피스톤(12)과 피스톤로드(13)가 좌측으로 슬라이드되고, 이에 따라, 도 5에 도시한 바와 같이, 개폐도어(3)가 좌측으로 슬라이드되어 열린 상태를 유지한다.Accordingly, as the elastic member 14 is compressed, the piston 12 and the piston rod 13 slide to the left, and accordingly, as shown in FIG. 5 , the opening/closing door 3 is slid to the left and opened. to keep

그리고, 화재가 발생되어 화재경보기가 작동되면, 상기 슬라이드구동수단(4)이 작동되어 상기 개폐도어(3)가 우측으로 슬라이드시켜 닫는다.Then, when a fire occurs and the fire alarm is operated, the slide driving means 4 is operated to slide the opening/closing door 3 to the right to close it.

이때, 정전이나 슬라이드구동수단(4)에 고장이 발생된 경우, 상기 개폐도어(3)는 닫히지 않게 된다.At this time, when a power failure or a failure occurs in the slide driving means 4, the opening/closing door 3 is not closed.

한편, 상기 스프링클러(5)의 분사노즐(5b)은 정전과 상관없이 작동되어, 물을 분사하게 된다.On the other hand, the spray nozzle (5b) of the sprinkler (5) is operated irrespective of the power outage, thereby spraying water.

그리고, 도 8에 도시한 바와 같이, 상기 분사노즐(5b)을 통해 물이 분사되면, 상기 급수관(5a) 내부의 압력이 매우 낮게 낮아지게 되며, 이에 따라, 상기 제2 챔버(11b) 내부의 압력 역시 낮아지게 된다.And, as shown in FIG. 8, when water is injected through the injection nozzle 5b, the pressure inside the water supply pipe 5a is lowered to a very low level, and accordingly, the inside of the second chamber 11b The pressure is also lowered.

이때, 상기 제1 챔버(11a)에 있는 탄성부재(14)의 탄성에 의해 상기 피스톤(12)과 피스톤로드(13)가 제2 챔버(11b)쪽으로 밀려나면서, 도 9에 도시한 바와 같이, 상기 개폐도어(3)가 닫히는 쪽으로 슬라이드되어 개폐도어(3)가 닫히게 된다.At this time, as the piston 12 and the piston rod 13 are pushed toward the second chamber 11b by the elasticity of the elastic member 14 in the first chamber 11a, as shown in FIG. 9 , The opening/closing door (3) slides toward the closing side to close the opening/closing door (3).

그리고, 상기 개폐도어(3)가 닫힌 상태에서, 방화유리자동문의 전방 또는 후방에 발생된 화재에 의해 방화유리자동문이 가열될 경우, 도 10에 도시한 바와 같이, 상기 보조분사노즐(21)이 개방되어 방화유리자동문의 전방 또는 후방으로 자동으로 물을 배출함으로, 화재의 열에 의해 방화유리자동문이 가열 및 변형 또는 손상되는 것을 최소화한다.In addition, when the automatic fire glass door is heated by a fire generated in the front or rear of the fire glass automatic door while the opening/closing door 3 is closed, as shown in FIG. 10 , the auxiliary spray nozzle 21 is By automatically discharging water to the front or rear of the fire glass automatic door when it is opened, it minimizes the heating, deformation, or damage of the fire glass automatic door by the heat of the fire.

이와 같이 구성된 방화유리자동문은 스프링클러(5)의 급수관(5a)을 통해 공급되는 물의 압력을 이용하여 개폐도어(3)를 슬라이드시키는 보조개폐수단(10)을 이용하여, 분사노즐(5b)이 개방되면 자동으로 개폐도어(3)가 닫히는 방향으로 슬라이드되도록 함으로, 화재발생시 슬라이드구동수단(4)에 고장이 발생되더라도 자동으로 닫히게 되는 장점이 있다.The automatic fire glass door constructed in this way uses the auxiliary opening/closing means 10 for sliding the opening/closing door 3 using the pressure of water supplied through the water supply pipe 5a of the sprinkler 5, and the spray nozzle 5b is opened. By automatically sliding the opening/closing door (3) in the closing direction, there is an advantage in that it is automatically closed even if a failure occurs in the slide driving means (4) in the event of a fire.

또한, 방화유리자동문의 전방 또는 후방에 발생된 화재에 의해 방화유리자동문이 가열될 경우, 상기 보조분사노즐(21)이 개방되어 방화유리자동문의 전방 또는 후방으로 자동으로 물을 배출함으로, 화재의 열에 의해 방화유리자동문이 가열 및 변형 또는 손상되는 것을 최소화할 수 있는 장점이 있다.In addition, when the automatic fire protection door is heated by a fire occurring in the front or rear of the fire glass automatic door, the auxiliary spray nozzle 21 is opened and water is automatically discharged to the front or rear of the fire glass automatic door. There is an advantage in that it can minimize the heating, deformation, or damage of the fire glass automatic door due to heat.
