본 고안은 축압식소화기용 밸브에 관한 것으로, 더욱 상세하게는 밸브 관로의 급격한 단면적 변화에 의한 소화약제 유동 압력손실을 최소화할 수 있는 밸브의 구조에 관한 것이다.The present invention relates to a valve for an accumulator type fire extinguisher, and more particularly, to a structure of a valve capable of minimizing extinguishing agent flow pressure loss due to a rapid cross-sectional area change of a valve pipeline.

통상적으로 축압식소화기용 밸브는 사이펀을 입구에 연결한 후 소화약제가 담긴 용기에 부착되며, 밸브를 개방하여 압축가스를 충진한 다음 밸브를 닫은 상태로 유지하다가 유사시에는 밸브를 개방하여 용기 내의 압축가스가 소화약제를 사이펀과 밸브를 통하여 외부로 방출하여 화재를 진압하는데 사용된다. 도 1은 종래의 일반적인 축압식소화기의 구조를 나타낸 것이고, 도 2는 종래의 밸브구조를 나타낸 것이다.Normally, the valve for a pressure fire extinguisher is connected to a container containing a fire extinguishing agent after connecting a siphon to an inlet, and the valve is opened to fill compressed gas, and the valve is kept closed. Is used to extinguish fire by releasing extinguishing agents through siphons and valves. Figure 1 shows the structure of a conventional general pressure fire extinguisher, Figure 2 shows a conventional valve structure.

종래의 밸브는 원통형 내부 관로에 단턱(51)을 형성하고 상기 단턱(51)의 모서리부분을 스템(72)을 구비하고 스프링(3)에 의해 탄지 되는 합성고무실링(71)이 차폐하는 구조를 가지며, 유사시 소화기 작동을 위해 상기 밸브체(5)의 가이드 구멍에서 슬라이딩 되는 상기 스템(72)의 외부 돌출부분을 수동레버나 전동 액추에이터로 눌러서 상기 단턱(51)과 상기 합성고무실링(71) 사이에 공간을 확보하면 용기 내에 충진된 압축가스에 의해 소화약제는 사이펀(2)과 밸브 관로 및 차단부를 지나 노즐을 통해 외부로 방출되는데, 이때 사이펀(2)을 통과한 소화약제의 일부는 약제유동방향에 직각 단면으로 형성된 디스크형 합성고무실링의 하단부(711)에 충돌한 후 통로로 유동하고 다시 상기 단턱(51)에 충돌한 후 밸브 차단부를 통과하게 된다. 이와 같이 관로 내부의 단면적이 급격하게 변하는 구조는 소화약제의 유동을 심하게 방해하여 균일한 소화약제 방출을 어렵게 하고 압력손실을 증대시키는 문제가 있다.Conventional valves have a structure that forms a step 51 in a cylindrical inner conduit and has a stem 72 around the edge of the step 51 and is shielded by a synthetic rubber seal 71 supported by a spring 3. And press the outer projection of the stem 72, which slides in the guide hole of the valve body 5, in case of fire extinguisher with a manual lever or an electric actuator, between the step 51 and the synthetic rubber seal 71. When the space is secured, the extinguishing agent is discharged to the outside through the nozzle through the siphon (2), the valve line and the blocking part by the compressed gas filled in the container, where a part of the extinguishing agent passing through the siphon (2) After impinging on the lower end portion 711 of the disk-shaped synthetic rubber seal formed in a cross-section perpendicular to the direction flows through the passage and impinges again to the step 51 and passes through the valve blocking portion. As such, the structure in which the cross-sectional area inside the pipeline changes abruptly severely disturbs the flow of the extinguishing agent, making it difficult to uniformly discharge the extinguishing agent and increasing the pressure loss.

본 고안은 상기한 종래의 문제를 해결하기 위해 안출한 것으로서, 축압식소화기 밸브 내부관로의 급격한 단면적 변화를 최소화하여 소화약제 유동을 원활하게 하고 압력손실을 최소화한 밸브를 제공함에 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, and aims to provide a valve that smoothes the flow of the extinguishing agent and minimizes the pressure loss by minimizing the rapid change in the cross-sectional area of the accumulator fire valve.

본 고안은 상기한 목적을 달성하기 위해, 밸브체의 원통형 내부관로에 단턱을 형성하고 상기 단턱의 모서리부분을 합성고무실링이 차폐하는 구조를 가지며, 입구 측에 사이펀을 연결한 후 소화약제가 담긴 용기에 결합되는 소화기 밸브에 있어서, 상기 단턱이 형성되는 관로의 넓은 쪽 내주 코너공간에 원추경사내면을 가진 경사단턱을 형성하고 상기 합성고무실링 하단부에 원추형상 돌기를 형성하여 급격한 단면적 변화를 최소화하도록 구성하였다.In order to achieve the above object, the present invention has a structure in which a stepped pipe is formed in a cylindrical inner conduit of a valve body, and a synthetic rubber sealing is shielded at an edge of the stepped pipe. In the fire extinguisher valve coupled to the container, to form a sloped stepped with a conical inclined surface in the inner peripheral space of the wide side of the pipe is formed stepped to form a conical projection at the bottom of the synthetic rubber sealing to minimize the rapid cross-sectional area change Configured.

이하, 본 고안에 따른 바람직한 실시 예를 첨부한 도면을 참조로 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail as follows.

도 3은 본 고안에 따른 축압식소화기 밸브의 조립단면을 도시한 것으로서, 사이펀(2)이 연결되는 밸브 입구 측의 넓은 관로에서 밸브차단부의 단턱(51)을 형성하기 위해 좁은 단면적으로 급수축되기 직전의 관로 코너공간에 원추경사내면을 가진 경사단턱(52)을 형성하고, 스프링에 의해 탄지 되어 상기 단턱의 모서리 밸브차단부에 접하는 합성고무실링(71)의 차단면 반대쪽의 하단부(711)에 원추형상 돌기(712)를 형성함으로써, 밸브가 개방됨에 따라 유동하는 소화약제 일부가 상기 합성고무실링 하단부에 경사면으로 충돌하여 압력손실을 줄일 수 있을 뿐만 아니라 스프링에 의해 탄지 되지만 스템에 의해 외팔보 형태로 지지 되는 합성고무실링(71)의 충격 떨림 현상을 최소화할 수 있게 하였고, 소화약제가 밸브차단부의 단턱을 통과할 때에도 원추경사내면으로 서서히 좁아진 관로를 유동하게 하여 압력손실을 최소화하였다.Figure 3 shows the assembling cross section of the pressure-digestive fire extinguisher valve according to the present invention, just before the water supply shaft to the narrow cross section to form a step 51 of the valve blocking portion in the wide conduit of the valve inlet side to which the siphon 2 is connected The inclined stepped jaw 52 having a conical inclined surface is formed in a conduit corner space of the conduit, and is conical in the lower end 711 opposite to the blocking surface of the synthetic rubber seal 71 which is supported by a spring and is in contact with the corner valve cutout of the stepped jaw. By forming the upper protrusion 712, a part of the extinguishing agent that flows as the valve is opened impinges on the inclined surface at the lower end of the synthetic rubber seal to reduce the pressure loss and is supported by the spring but supported by the stem in a cantilevered shape. The impact vibration of the synthetic rubber seal 71 can be minimized, and even when the extinguishing agent passes through the stepped portion of the valve blocking portion, the conical slope is reduced. The pressure narrowed to minimize the pressure loss by allowing the pipe narrowed to the inner surface.

이상과 같은 구성으로 밸브 내부관로 단면적의 급격한 변화 때문에 생기는 소화약제의 유동 압력손실을 최소화할 수 있고, 소화약제가 효율적으로 방출되도록 할 수 있게 한 축압식소화기용 밸브를 제공할 수 있다. With the above configuration, it is possible to minimize the flow pressure loss of the extinguishing agent caused by the rapid change in the cross-sectional area of the valve inner pipe, and to provide a pressure-digestive valve capable of efficiently discharging the extinguishing agent.
