A flow path switching valve is provided. The flow path switching valve comprises: a valve body which has, at one side thereof, an inflow pipe and first and second outflow pipes, and which includes an inflow hole corresponding to one end of the inflow pipe, and first and second cam accommodating grooves corresponding to one end of each of the first and second outflow pipes; a cam disc including first and second cams accommodated, respectively, in the first and second cam accommodating grooves so as to block the outflow of a specific gas, a first and a second cam compressing protrusion, which compresses the first cam and/or the second cam so as to switch the flow path of the specific gas, and a first or a second cam compressing protrusion, which compresses either the first cam or the second cam so as to block the outflow of the specific gas; a cover coupled to the valve body while covering the cam disc; and a motor which is provided on the cover, and which rotates the cam disc so as to switch the flow path of the specific gas. The motor switches the flow path of the specific gas so that the specific gas flows out to the outside if the concentration of the specific gas at the location to which the specific gas is supplied is higher than a set value, and switches the flow path of the specific gas so that the specific gas flows out to the location to which the specific gas is supplied if the concentration of the specific gas at the location to which the specific gas is supplied is lower than the set value. L'invention concerne une soupape de commutation de trajet d'écoulement. La soupape de commutation de trajet d'écoulement comprend : un corps de soupape qui a, sur un côté de celui-ci, un tuyau d'entrée et de premier et second tuyaux de sortie, et qui comprend un trou d'entrée correspondant à une extrémité du tuyau d'entrée, et de première et seconde rainures de réception de came correspondant à une extrémité de chacun des premier et second tuyaux de sortie ; un disque de came comprenant des première et seconde cames logées, respectivement, dans les première et seconde rainures de réception de came de façon à bloquer l'écoulement d'un gaz spécifique, une première et une seconde saillie de compression de came, qui comprime la première came et/ou la seconde came de façon à commuter le trajet d'écoulement du gaz spécifique, et une première ou une seconde saillie de compression de came, qui comprime soit la première came, soit la seconde came de façon à bloquer l'écoulement du gaz spécifique ; un couvercle accouplé au corps de soupape tout en recouvrant le disque de came ; et un moteur qui est disposé sur le couvercle, et qui fait tourner le disque de came de façon à commuter le trajet d'écoulement du gaz spécifique. Le moteur commute le trajet d'écoulement du gaz spécifique de telle sorte que le gaz spécifique s'écoule vers l'extérieur si la concentration du gaz spécifique à l'emplacement auquel le gaz spécifique est fourni est supérieure à une valeur définie, et commute le trajet d'écoulement du gaz spécifique de telle sorte que le gaz spécifique s'écoule vers l'extérieur jusqu'à l'emplacement auquel le gaz spécifique est fourni si la concentration du gaz spécifique à l'emplacement auquel le gaz spécifique est fourni est inférieure à la valeur définie. 유로 전환 밸브가 제공된다. 이 유로 전환 밸브는 일 측에 유입관, 및 제 1 및 제 2 유출관들을 가지되, 유입관의 일단에 해당하는 유입 홀, 및 제 1 및 제 2 유출관들 각각의 일단에 해당하는 제 1 및 제 2 캠 수용 홈들을 포함하는 밸브 몸체, 제 1 및 제 2 캠 수용 홈들 각각에 수용되어 특정 기체의 유출을 차단하는 제 1 및 제 2 캠들, 제 1 및 제 2 캠들 중 적어도 하나를 압축하여 특정 기체의 유로를 전환하는 제 1 및 제 2 캠 압축용 돌기, 및 제 1 또는 제 2 캠들 중 하나를 압축하여 특정 기체의 유출을 차단하는 제 1 또는 제 2 캠 압축용 돌기를 포함하는 캠 디스크, 캠 디스크를 덮으면서 밸브 몸체와 결합되는 커버, 및 커버 상에 구비되되, 캠 디스크를 회전시켜 특정 기체의 유로를 전환하는 모터를 포함한다. 모터는 특정 기체가 공급되는 곳의 특정 기체의 농도가 설정 값보다 높은 경우 특정 기체의 유로를 전환하여 외부로 특정 기체를 유출하도록 하고, 그리고 특정 기체가 공급되는 곳의 특정 기체의 농도가 설정 값보다 낮을 경우 특정 기체의 유로를 전환하여 특정 기체가 공급되는 곳으로 특정 기체를 유출하도록 한다.
