Abstract

The present invention relates to a fire hydrant to check pressure. More specifically, water having a hydraulic pressure passes through a draining hole having an inlet and an outlet formed in an intermediate portion of a valve bar to enable a user to check the hydraulic pressure with a pressure gauge connected to an upper portion. As such, the draining hole is formed in the intermediate portion of the valve bar installed inside a fire hydrant, and a hydraulic pressure blocking ball valve is connected to an upper outlet, and the pressure gauge is attached to the upper outlet to enable the user to measure the hydraulic pressure without opening the fire hydrant. Moreover, a transparent window is attached to a cap to enable the user to check the hydraulic pressure with the naked eye without an additional equipment to check whether or not the fire hydrant is normally operated and if there is a leakage in a drain.

Description

압력체크용 소화전{The fire hydrant for pressure check}The fire hydrant for pressure check

본 발명은 지상소화전에 관한 것으로써, 더욱 상세히 설명하면 지상에 설치된 소화전 본체 내부의 밸브막대에 유입구와 유출구가 있는 배수공을 형성하고, 유출구에는 수압 차단용 볼밸브를 연결하고 압력게이지를 부착하여 소화전의 개폐없이도 수압을 측정할수 있도록하며, 투명창이 부착된 상부 캡을 통하여 압력을 확인하여 소화전의 정상작동 유무와 소화전에 연결된 배수관의 누수 여부를 확인할수 있는것을 특징으로 하는 지상소화전에 관한 것이다.The present invention relates to a ground fire hydrant, and more particularly, to a fire hydrant with a drain hole having an inlet port and an outlet port formed in a valve rod inside a fire hydrant body installed on the ground, connecting a ball valve for water pressure shutoff to an outlet port, And it is possible to confirm the normal operation of the fire hydrant and the leakage of the water pipe connected to the fire hydrant by confirming the pressure through the upper cap with the transparent window.

일반적으로 지상소화전은 화재발생시 화재진압 및 소방차의 급수공급을 위하여 설치되며 토출구가 지상으로 노출되게 구성된것으로서, 그 구성은 지하에 매설된 배수관과 연결되며 밸브가 구비된 밸브통과 상기 밸브통의 상측에 연결되고 지상으로 노출되어 측면으로 토출구가 형성되는 소화전 본체 및 내부에 설치된 디스크와 밸브막대가 연결된 상태에서 소화전 본체의 상측으로 돌출되어 사용자가 외부에서 디스크의 개폐조작을 할수있게 하는 캡으로 구성된다.Generally, a ground fire hydrant is installed for fire suppression and fire supply of a fire truck when a fire occurs, and is configured to expose the discharge port to the ground. The composition is connected to a drain pipe buried in the underground and passes through a valve having a valve. And a cap which is protruded to the upper side of the hydrant main body in a state where the valve bar is connected with the disk installed inside and the user can open and close the disk from the outside.

종래의 지상소화전은 정상작동 유무를 점검하기 위해 월1회정도 관할 소방서에서 소화전 렌지로 상부캡을 조작하여 유출구를 통한 소방용수의 배수로 확인한다.Conventional ground fire hydrants are checked once a month to check the normal operation of the fire hydrant by operating the upper cap with a fire fighting stove at the local fire station and discharging the water through the outlet.

따라서, 소화전의 작동유무만 확인이 가능하며 화재진압시 필요한 적정 수압의 판단은 어려운 실정이다.Therefore, it is possible to confirm whether or not the fire hydrant operates only, and it is difficult to judge the proper water pressure necessary for the fire suppression.

또한, 소화전의 수압을 확인하기 위해서는 별도의 수압계를 유출구에 부착하여야 하는 번거로움이 있으며 1회 점검에 따른 소화용수의 배출량은 평균 10ℓ로 수돗물의 낭비를 초래하고 평상시 배수관의 누수로 인한 소화전의 수압저하는 확인이 불가능한 문제점이 있다.In addition, it is troublesome to attach a separate hydraulic system to the outlet to check the water pressure of the fire hydrant, and the discharge amount of the water for fire extinguishing water per one time is an average of 10 liters, resulting in waste of tap water. There is a problem that the water pressure drop can not be confirmed.

상기와 같은 문제점을 해결하기 위한 과제로 본 발명은 소화전 렌지를 이용한 상부캡 조작없이 소화전 본체 내부에 설치된 압력게이지의 압력을 확인하는 방법으로 소화전의 이상유무와 배수관의 누수여부를 확인하고 수돗물의 낭비를 방지하는것을 목적으로 한다.In order to solve the above problems, the present invention provides a method of confirming the pressure of a pressure gauge installed inside a fire hydrant main body without operating an upper cap using a fire fighting stove to check whether there is an abnormality in a fire hydrant or leakage of a water pipe, .

본 발명은 지상에 설치된 소화전 본체 내부의 밸브막대에 유입구와 유출구가 있는 배수공을 만들고 유출구에는 수압 차단용 볼밸브를 연결하고 압력게이지를 부착하여 별도의 상부 캡 조작없이 수압을 측정할수 있도록 하고, 투명창이 부착된 상부 캡을 통해 육안으로 압력을 확인하여 소화전의 이상유무와 배수관의 누수여부를 확인하고 수돗물의 낭비를 막는 지상소화전을 제공한다.In the present invention, a drain hole having an inlet port and an outlet port is formed in a valve rod inside a fire hydrant body installed on the ground, a water pressure-blocking ball valve is connected to an outlet port, a pressure gauge is attached, Through the upper cap with the window, the pressure is visually checked to check whether there is a fire hydrant, whether the water pipe is leaking, and provide a ground fire hydrant that prevents waste of tap water.

본 발명은 지상소화전의 수압을 내부에 설치된 압력게이지로 손쉽게 확인이 가능하고, 수돗물의 낭비를 방지하는데 효과가 있다. 또한 각 소화전별로 수압자료를 DB자료로 구축하여 관할 소방서에서 정기점검후 이상유무를 지방자치단체로 통보하여 배수관의 누수여부를 점검 할수있는 효과가 있다.The present invention can easily confirm the water pressure of a ground fire hydrant by a pressure gauge installed therein and is effective in preventing waste of tap water. In addition, it is effective to build water pressure data for each fire hydrant with DB data and to check the leakage of drain pipe by informing the local governments about the abnormality after periodical inspection at the fire department of the jurisdiction.

또한, 본 발명은 지상소화전을 설치하고 있는 모든 지방자치단체에 사용이 가능하며 배수관의 누수 의심이나 발생시 소화전을 통한 압력 확인으로 누수 지점을 손쉽게 확인할수 있으며, 별도의 장비없이 육안으로 수압 확인이 가능하므로 수시점검을 통한 배수관 관리로 유수율 향상 및 예산 절감에 효과가 있다.In addition, the present invention can be applied to all local governments installing ground fire hydrants, and it is possible to easily check the leakage point by confirming the pressure through the fire hydrant upon suspicion of leakage of the water pipe or occurrence, and the water pressure can be visually confirmed without any equipment Therefore, it is effective to improve the flow rate and reduce the budget by managing the drain pipe through frequent inspection.
