따라서, 화제가 발생되면 자동으로 상기 상부기대(12)가 슬라이드되어 관통공(11a)을 개방하므로써, 상기 관통공(11a)을 통해 관로(1) 내부에 소화액 등을 주입하여, 화제를 신속하게 제압할 수 있는 장점이 있다.Accordingly, when the topic is generated, the upper expectation 12 is automatically slid to open the through hole 11a, thereby injecting a digestive fluid or the like into the conduit 1 through the through hole 11a, thereby rapidly adding the topic. It has the advantage of overpowering.

또한, 관로(1) 내부에 화제가 발생되면 상기 솔레노이드장치(70)를 작동시켜 접속단자(60)와 커넥터(50)의 연결을 자동으로 차단하므로써, 화제에 의해 발생되는 합선 등에 의해 연결대본체(20)가 손상되는 것을 방지할 수 있다.In addition, when a topic is generated in the conduit 1, the solenoid device 70 is operated to automatically cut off the connection between the connection terminal 60 and the connector 50, thereby connecting the main body by a short circuit generated by the topic. 20) can be prevented from being damaged.
