Description
본 고안은 액화석유가스 탱크로리의 긴급차단장치에 관한 것으로서, 보다 상세히는 액화석유가스 탱크로리에 화재가 발생하였을 때 무선으로 또는 온도 감지로써 가스배출을 차단시키는 액화석유가스 탱크로리의 긴급차단장치에 관한 것이다.The present invention relates to an emergency shutoff device for a liquefied petroleum gas tank lorry, and more particularly, to an emergency shutoff device for a liquefied petroleum gas tank lorry to shut off the gas by wireless or temperature sensing when a fire occurs in the liquefied petroleum gas tank lorry. .
도 1은 종래의 액화석유가스 탱크로리의 긴급차단장치를 도시한 구성도로서, 탱크(10)의 하부에 솔레노이드(12)가 장착되고, 상기 솔레노이드(12)는 밸브(13, 13')를 개폐한다. 상기 솔레노이드(12)는 풀림버튼(11, 11') 및 레버(17, 17')에 의해서 각각의 밸브(13, 13')를 제어하고, 긴급차단볼(14)에 의해서 밸브 전체를 일시에 제어한다. 또한 가스감지센서(15)에서 가스 누출을 감지하면 솔레노이드(12)가 작동하여 밸브를 크로즈시킨다.1 is a block diagram showing an emergency shutoff device of a conventional liquefied petroleum gas tank lorry, the solenoid 12 is mounted to the lower portion of the tank 10, the solenoid 12 opens and closes the valve (13, 13 ') do. The solenoid 12 controls the respective valves 13 and 13 'by the release buttons 11 and 11' and the levers 17 and 17 ', and the entire valve is temporarily closed by the emergency shutoff ball 14. To control. In addition, when the gas detection sensor 15 detects a gas leak, the solenoid 12 operates to close the valve.
상기와 같은 종래의 긴급차단장치는 화재 발생시 작업자가 밸브박스(16)내로 접근하기가 힘들어 풀림버튼(11, 11')이나 레버(17, 17') 및 긴급차단밸브레버(14)를 작동시키기 힘들고, 화재가 발생하여도 가스가 누출되지 않은 상태라면 가스감지센서(15)에 의해서 솔레노이드(12)가 밸브를 차단시키지 않게 되는 문제가 있다.In the conventional emergency shutoff device as described above, it is difficult for an operator to approach the valve box 16 in the event of a fire, thereby operating the release buttons 11 and 11 'or the levers 17 and 17' and the emergency shutoff valve lever 14. If the gas is hard to leak even if a fire occurs, there is a problem that the solenoid 12 does not block the valve by the gas detection sensor 15.
도 2는 종래의 탱크로리의 기름배출차단장치를 도시한 구성도로서, 탱크(22)의 하부에 저면밸브(20)가 장착되고, 상기 저면밸브(20)의 각각은 와이어(24)에 의해서 에어실린더(28)와 연결되어 상기 에어실린더(28)의 작동에 의해서 개폐된다.2 is a block diagram illustrating a conventional oil discharge blocking device of a tank lorry, in which a bottom valve 20 is mounted at a lower portion of the tank 22, and each of the bottom valves 20 is connected to air by a wire 24. It is connected to the cylinder 28 is opened and closed by the operation of the air cylinder 28.
상기 에어실린더(28)는 에어벨브(30, 32)를 통하여 에어탱크(70)와 연결되고, 상기 에어밸브(30, 32)는 송신기(30)에서 송신된 무선신호를 수신부(40)에서 수신받아 콘트롤러(36)의 제어에 의해서 개폐된다.The air cylinder 28 is connected to the air tank 70 through the air valve 30, 32, the air valve 30, 32 receives the radio signal transmitted from the transmitter 30 in the receiver 40 It is opened and closed by the control of the controller 36.
따라서 화재발생시 작업자가 송신기(30)를 작동시키면, 수신부(40)에서 이를 수신하여 콘트롤러(36)의 제어에 의해서 에어밸브(30, 32)가 오픈되어 에어탱크(34)내의 에어가 에어실린더(28)로 공급되어, 에어실린더(28)가 와이어(24)를 당겨서 저면밸브(20)가 크로즈된다.Therefore, when a worker operates the transmitter 30 in the event of a fire, the receiver 40 receives it and the air valves 30 and 32 are opened by the control of the controller 36 so that the air in the air tank 34 is air cylinder ( 28, the air cylinder 28 pulls the wire 24, the bottom valve 20 is closed.
상기와 같은 종래의 기름배출차단장치는 하나의 와이어(24)로써 다수개의 저면밸브(20)를 개폐시키므로, 개폐 작동이 부정확하며, 화재발생시 에어탱크와 에어밸브가 먼저 불타버리는 문제점이 있고, 에어실린더 장치의 유지 보수가 평상시 어렵게 된다.Since the conventional oil discharge blocking device as described above opens and closes the plurality of bottom valves 20 by one wire 24, the opening and closing operation is incorrect, and there is a problem that the air tank and the air valve burn out first when a fire occurs. Maintenance of the cylinder device is usually difficult.
