Fire Hydrant Drainage Check and Inspection Device
A fire hydrant drainage check inspection device comprises: a transparent tube drawn into a fire hydrant discharge pipe and extending at least from a discharge pipe to the bottom of an opening and closing valve; and a counterflow prevention valve watertightly coupled to the transparent tube at one end so that the remaining water of the fire hydrant is drawn into the transparent tube, and blocking an outward flow of the water drawn into the transparent tube, thereby capable of easily checking the remaining water in the fire hydrant.
소화전 배수확인 점검기구는 소화전 토출관구로 인입되어 적어도 토출관구로부터 개폐밸브 바닥까지의 길이를 갖고 연장 형성된 투명튜브 및 투명튜브가 일단에 수밀하게 결합되어 소화전의 잔수가 투명튜브 내측방향으로 인입되도록 하며 투명튜브 내측에 인입된 물의 외측방향 유동을 차단하는 역류방지밸브를 포함할 수 있다.
