상기와 같은 구성을 갖는 본 고안에 따른 액화가스플럭스 감지스위치(10)는 가스관상에 연통되게 장착되며, 액화가스가 가스관을 흐를 때에는 액화가스가 액화가스유입공(11a)을 통하여 하우징(11)내로 유입될 때 액화가스의 압력에 의해 상기 마그네틱개폐구(14)는 탄성부재(15)를 압축시키면서 유입구(13)쪽으로 밀려나서 스위치(16)가 장착된 위치에서 정지하게된다. 상기와 같이 마그네틱개폐구(14)가 스위치(16)가 장착된 위치에 정지하게되면 마그네틱개폐구(14)의 자력이 스위치(16)의 접점까지 미치되어서 상측 접점이 자력에 의해 하방으로 당겨지면서 상호 접점이 접속되게 됨으로 스위치(16)와 전기적으로 연결된 표시등(도시되지 않음)이 점등됨으로 가스관내에 액화가스가 흐르고 있다는 것을 사용자가 알 수 있는 것이며, 하우징(11)내로 유입된 액화가스는 상기 유입구(13)의 액화가스유로(13c)와 다수개의 서브유로(13d)를 거쳐 연결구(12)의 액화가스유로(12c)를 지나 가스관으로 흐르게 되는 것이다.Liquefied gas flux detection switch 10 according to the present invention having the configuration as described above is mounted in communication on the gas pipe, when the liquefied gas flows through the gas pipe liquefied gas through the liquefied gas inlet hole (11a) the housing (11) The magnetic opening 14 is pushed toward the inlet 13 while compressing the elastic member 15 by the pressure of the liquefied gas when it is introduced into the switch 16 is stopped in the mounted position. As described above, when the magnetic opening 14 stops at the position where the switch 16 is mounted, the magnetic force of the magnetic opening 14 extends to the contact of the switch 16, and the upper contact is pulled downward by the magnetic force, thereby making mutual contact. The user can know that the liquefied gas flows in the gas pipe by turning on the indicator (not shown) electrically connected to the switch 16 by the connection, and the liquefied gas introduced into the housing 11 is the inlet. The liquefied gas flow path 13c and the plurality of sub-flow paths 13d of (13) pass through the liquefied gas flow path 12c of the connector 12 to the gas pipe.
만약 가스관내에 액화가스가 아닌 기화가스가 흐르게된다면 기화가스의 압력이 액화가스의 압력보다 낮음으로 상기 마그네틱개폐구(14)는 탄성부재(15)의 탄성력에 의해 스위치(16)가 장착된 위치까지 밀려나지 못함으로 마그네틱개폐구(14)의 자력이 스위치(16)에 미치지 않게 됨으로 스위치(16)의 상측 접점은 자체복원력에 의해 상방으로 복귀됨으로 상호 접점이 단락되어 표시등이 소등되게 됨으로 사용자는 표시등의 소등된 것을 확인함으로써 가스관내에 기화가스가 흐르고 있다는 것을 신속하게 확인할 수 있음으로 이에 대한 적절한 조치를 신속하게 취할 수 있는 것이다.If vaporized gas other than liquefied gas flows in the gas pipe, the pressure of the vaporized gas is lower than the pressure of the liquefied gas, so that the magnetic opening 14 is moved to the position where the switch 16 is mounted by the elastic force of the elastic member 15. Since the magnetic force of the magnetic opening and closing 14 does not reach the switch 16 because it cannot be pushed out, the upper contact of the switch 16 is returned to the upper side by self-resilience, and the contact is short-circuited so that the light is turned off. By confirming that the light is turned off, it is possible to quickly confirm that gaseous gas is flowing in the gas pipe, so that appropriate measures can be promptly taken.
이상으로 설명한 본 고안에 의하면, 액화가스가 흐르는 가스관에 설치되어 액화가스가 흐를 때 액화가스가 흐르고 있음을 표시등을 점등하여 표시하고, 기화가스가 흐를 때 표시등을 소등하여 표시하여 알려줌으로써 사용자가 액화가스가 정상적으로 흐르는지를 안전하고 정확하게 확인할 수 있는 효과를 갖는다.According to the present invention described above, the user is liquefied by being installed in the gas pipe through which the liquefied gas flows, the indicator lights up to indicate that the liquefied gas is flowing when the liquefied gas flows, and turns off the indicator to indicate when the liquefied gas is flowing It has the effect of ensuring safe and accurate gas flow.
