Description

소방용 더블디스크 게이트 밸브{Double disc gate valve for firefighting}Double disc gate valve for firefighting}

본 발명은 소방용 게이트 밸브에 관한 것으로 더 상세하게는 지진이나 기타 충격으로부터 손상되지 않으면서도 설치 공간을 줄일 수 있으면서도 개폐에 소요되는 시간과 노력을 절감할 수 있는 더블디스크 기반의 소방용 게이트 밸브에 관한 것이다.The present invention relates to a fire-fighting gate valve, and more particularly, to a double-disk-based fire-fighting gate valve that can reduce the installation space and reduce the time and effort required for opening and closing without being damaged from an earthquake or other impact. .

종래에는 소방용 밸브로서 버터플라이 밸브가 사용되어 왔다. 도 1은 종래 기술에 의한 레버를 구비하는 소방용 버터플라이 밸브를 사시도로써 나타내었다. 도 1을 참조하면 종래 기술에 의한 레버를 구비하는 버터플라이 밸브는 원형의 밸브판과, 상기 밸브판이 수용되어 밸브판의 회전에 의하여 유체의 흐름이 제어되는 밸브실과, 상기 밸브실의 밸브판에 축 결합되어 일체로 회전하는 밸브축으로 구성된다. 하지만 상기와 같은 소방용 버터플라이 밸브는 레버의 회전에 의하여 밸브 열림량을 판단하여야 하므로 열림량을 정확하게 판단하는 것이 용이하지 않으며, 밸브가 설치된 현장에서만 밸브 열림을 확인할 수 있는 문제점이 있었다.Conventionally, a butterfly valve has been used as a valve for fire fighting. 1 is a perspective view showing a butterfly valve for a fire having a lever according to the prior art. Referring to FIG. 1, a butterfly valve having a lever according to the prior art includes a circular valve plate, a valve chamber in which the valve plate is accommodated and fluid flow is controlled by rotation of the valve plate, and a valve plate in the valve chamber. It is composed of a valve shaft that is integrally rotated by being coupled to the shaft. However, the above-described fire-fighting butterfly valve has a problem in that it is not easy to accurately determine the amount of opening because the valve opening amount must be determined by the rotation of the lever.

이러한 문제점을 해결하기 위한 종래의 다른 기술이 대한민국 공개실용신안 실1998-066584호에 개시되어 있다. 도 2를 참조하면 종래의 소방용 게이트밸브는 핸들의 회전에 의하여 길이 방향으로 이동 가능한 밸브대를 포함하며 물탱크의 물을 소화전 또는 스프링 쿨러의 제어라인으로 토출하는 밸브에 적용된다. 하지만, 이와 같은 종래의 소방용 게이트밸브는 화재 발생시 또는 유지 보수시에 핸들을 돌려 밸브를 개폐하는데 상당한 시간과 노력이 필요할 뿐만 아니라 개폐 핸들이 상부로 노출되므로 설치 면적을 줄이는데 한계가 있다는 문제점이 있다. 또한, 양단부가 플랜지 결합되어 지진등으로 인한 충격발생시 굴절로 인하여 이음새에 누수가 발생할 가능성이 높다는 문제점이 있다.Another conventional technique for solving this problem is disclosed in the Republic of Korea Utility Model Publication 1998-066584. Referring to Figure 2, the conventional fire gate valve includes a valve seat movable in the longitudinal direction by rotation of the handle and is applied to a valve that discharges water from a water tank into a control line of a fire hydrant or sprinkler. However, such a conventional gate valve for firefighting has a problem in that it requires a considerable amount of time and effort to open and close the valve by turning the handle in the event of a fire or maintenance, as well as reducing the installation area because the open/close handle is exposed to the top. In addition, there is a problem that the joints of both ends are flanged, and there is a high possibility of leaks in the seam due to refraction when an impact due to an earthquake occurs.

본 발명은 상기한 문제점을 해결하기 위하여 개발된 것으로 본 발명이 이루고자 하는 기술적 과제는 지진이나 기타 충격으로부터 손상되지 않으면서도 고압의 소방수가 흐르는 소방수 라인에 적용하는 것이 가능할 뿐만 아니라 설치 공간을 줄일 수 있어 도심의 빌딩과 같이 공간이 협소한 장소의 소방 라인에 적용하는 것이 용이하고 개폐에 소요되는 시간과 노력을 절감할 수 있는 소방용 더블디스크 게이트 밸브를 제공하는 것이다.The present invention has been developed to solve the above problems, and the technical problem to be achieved by the present invention is that it is possible to reduce the installation space as well as to apply to a firefighter line through which high-pressure firefighters flow without being damaged from earthquakes or other impacts. It is to provide a double disc gate valve for firefighting that is easy to apply to a fire line in a place with limited space, such as a downtown building, and can save time and effort required for opening and closing.
