도 2 내지 3은 본 발명에 따른 소화용 니들밸브를 나타내고 있다.2 to 3 illustrate a fire extinguishing needle valve according to the present invention.
도시한 바와 같이 소화용 니들밸브는 밸브바디(11)의 일측에 수동으로 전후진 되도록 설치된 수동레버(12)와, 상기 수동레버(12)에 일단이 결합되어 에프형 밸브(30)의 동판(31)을 파괴하는 가동니들(13)로 구성되어진 것은 종래와 동일하며, 다만, 본 발명의 특징은 상기 가동니들(13)을 화약의 폭발력으로 가압시키도록 하는 것이다.As shown in the figure, the fire extinguishing needle valve has a manual lever 12 installed to be moved back and forth manually on one side of the valve body 11, and one end of the manual lever 12 is coupled to the copper plate of the F-type valve 30. The movable needle 13 which destroys 31 is the same as in the related art, except that the movable needle 13 is pressurized by the explosive force of the gunpowder.

상기 폭발부(15)는 내부에 화약(15a)이 충전시키고, 양측을 밀봉하여 습기침투를 방지하도록 하며, 일측에 도화선이 되는 전기회로(16)를 연결하는 것이다.The explosive part 15 is filled with gunpowder (15a), to seal both sides to prevent moisture penetration, and to connect the electrical circuit 16, which is a conductive wire to one side.
즉, 전기신호에 의해 화약(15a)이 충전된 폭발부(15)가 폭발하게 되면, 발생된 폭발력이 유로(14)를 통해 가동니들(13)의 일면을 가압시킴으로서, 가동니들(13)이 전진하여 에프형밸브(30)의 동판(31)을 파괴하는 것이다.That is, when the explosive part 15 filled with the gunpowder 15a is exploded by the electric signal, the generated explosive force presses one surface of the movable needle 13 through the flow path 14, whereby the movable needle 13 It moves forward and destroys the copper plate 31 of the F-type valve 30.
도 4 및 도 5는 본 발명의 소화용 니들밸브에 에프형밸브가 결합된 상태를 나타낸 도면이다.4 and 5 are views showing a state in which the F-type valve is coupled to the needle valve for fire extinguishing of the present invention.
고압가스탱크(20)의 상측에 결합된 에프형밸브(30)에 본 발명의 니들밸브(10)를 설치하고, 제어시스템의 화재감지기(미도시)에 화재가 감지되면 니들밸브(10)의 폭발부(15)에 전기신호를 가해 발생된 폭발력으로 니들밸브(10)의 가동니들을(13) 전진시켜 에프형밸브(30) 동판(31)을 파괴하게 된다.The needle valve 10 of the present invention is installed on the F-type valve 30 coupled to the upper side of the high pressure gas tank 20, and when a fire is detected by a fire detector (not shown) of the control system, the needle valve 10 The moving needle 13 of the needle valve 10 is advanced by the explosion force generated by applying an electrical signal to the explosion unit 15 to destroy the copper plate 31 of the F-type valve 30.
또한, 화약의 불발에 의해 조작이 불능 상태에서는 수동으로도 니들밸브(10)의 수동레버(12)를 전진시키게 되고, 이때도 가동니들(13)이 에프형밸브(30)의 동판(31)을 파괴하게 된다.In addition, the manual lever 12 of the needle valve 10 is advanced even in a state where the operation is impossible due to the inability to explode, and the movable needle 13 is the copper plate 31 of the F-type valve 30 even at this time. Will be destroyed.
상기와 같이 화재감지 신호에 의한 화약의 폭발 또는 수동으로 가동니들(13)을 전진시켜 에프형밸브(30)의 동판(31)을 파괴하게 되면, 고압가스탱크(10)의 내부에 충전되어진 소화액이 에프형밸브(30)의 유도구(32)와 토출구(33)를 통해 화재장소에 분출되어 화재을 초기에 진압시키도록 한다.As described above, when the explosives of the fire detection signal or the movable needle 13 is moved manually to destroy the copper plate 31 of the F-type valve 30, the extinguishing liquid filled in the high-pressure gas tank 10. Through the inlet port 32 and the discharge port 33 of the F-type valve 30, it is ejected to the fire place to extinguish the fire initially.
이때 유출구(34) 내부에 존재하여 있던 가스는 드레인너트(35)의 배출구(35a)를 통해 배출됨에 따라 오실레이터(36)가 후진되어 유도구(34)와 토출구(33)가 개방되는 것이다.(도 5참조)At this time, the gas existing in the outlet 34 is discharged through the outlet 35a of the drain nut 35 so that the oscillator 36 is reversed so that the inlet 34 and the outlet 33 are opened. 5)
도 6은 본 발명의 소화용 밸브에 기동밸브가 결합된 상태를 나타낸 도면이다. 이하 설명의 편의를 위해 본 발명의 소화용 니들 밸브와 종래의 니들밸브를 구분하며, 도 4 및 도 5와의 혼란을 방지하기 위해 에프형밸브와 고압가스탱크도 종래의 부호를 부여한다.6 is a view showing a state in which the starting valve is coupled to the fire fighting valve of the present invention. For the convenience of the following description, the fire needle valve and the conventional needle valve of the present invention are distinguished, and in order to prevent confusion with FIGS. 4 and 5, the F-type valve and the high pressure gas tank are also given the conventional codes.
도시한 바와 같이 소화용 니들밸브(10)에 기동밸브(40)를 연결하고, 상기 기동밸브(40)에 의해 복수개의 에프형밸브(2)가 결합된 고압가스탱크(1)를 순차적으로 개방시키는 구성을 설명한다.As shown in the drawing, the start valve 40 is connected to the needle valve 10 for fire extinguishing, and the high pressure gas tank 1 in which the plurality of F-type valves 2 are coupled by the start valve 40 is sequentially opened. The configuration to make it explain.
상기 기동밸브(40)도 에프형밸브(2)와 그 구조가 동일하며, 토출되는 고압가스가 화재장소에 분출되는 것이 아니고, 양측에 결합구(3d)가 형성된 종래의 니들밸브(3)에 연결되는 것이다.The starting valve 40 also has the same structure as the F-type valve 2, and the high-pressure gas discharged is not ejected to a fire place, but to the conventional needle valve 3 in which coupling holes 3d are formed at both sides. It is connected.
즉, 본 발명의 니들밸브(10)을 화약 또는 수동으로 가동니들(13)을 전진시키게 되면 기동밸브(40)의 동판(41)을 파괴하고, 이때 기동밸브(40)의 토출구(42)와 유도구(43)를 폐쇄하고 있던 오실레이터(44)가 개방되면서 기동밸브용 고압가스탱크(50)에 충전되어진 고압가스가 토출구(42)를 통해 분출되고, 이때 분출된 고압가스는 종래의 니들밸브(3)의 결합구(3d)로 전달된다.That is, when the needle valve (10) of the present invention to advance the movable needle 13 by gunpowder or manually destroys the copper plate (41) of the start valve (40), and the discharge port 42 of the start valve (40) As the oscillator 44 closing the induction port 43 is opened, the high pressure gas filled in the high pressure gas tank 50 for the starting valve is ejected through the discharge port 42, and the ejected high pressure gas is a conventional needle valve. It is delivered to the coupling sphere 3d of (3).
이렇게 종래의 니들밸브(3)의 결합구(3d)로 유입된 고압가스의 가압력에 의해 가동니들(3c)이 전진하여 에프형밸브(2)의 동판(2c)을 파괴함으로서, 에프형밸브(2)의 유도구(2a-1) 및 토출구(2a-2)를 폐쇄시키고 있는 오실레이터(2b)가 후진하면서 고압가스탱크(1)의 내부에 충진되어 있던 고압가스 즉, 소화액이 화재장소에 토출되어진다.Thus, the movable needle 3c is advanced by the pressing force of the high-pressure gas introduced into the coupling port 3d of the conventional needle valve 3, and the copper plate 2c of the F-type valve 2 is destroyed, thereby providing the F-type valve ( While the oscillator 2b closing the induction port 2a-1 and the discharge port 2a-2 of 2) retreats, the high pressure gas, that is, the extinguishing liquid, filled inside the high pressure gas tank 1 is discharged to the fire place. It is done.
즉, 기동밸브(40)에 의해 복수개의 고압가스탱크(1)를 개방시켜 소화액을 분사하는 것이다.That is, the extinguishing liquid is injected by opening the plurality of high pressure gas tanks 1 by the start valve 40.
이상 상세히 설명한 바와 같은 본 발명의 소화용 니들밸브에 화약이 충진되어진 폭발부를 설치하고, 상기 폭발부를 전기신호에 의해 폭발시키며, 이때 발생된 화약의 가압력으로 소화용 니들밸브의 가압니들을 동작시키도록 하여 수동으로 조작되던 니들밸브를 화약으로 간단히 조작할수 있는 것이다.An explosive part filled with gunpowder is installed in the extinguishing needle valve of the present invention as described in detail above, and the exploding part is exploded by an electric signal, and the pressure needle of the extinguishing needle valve is operated by the pressing force of the gunpowder generated at this time. The needle valve, which was operated manually, can be operated simply with gunpowder.
