Description

개폐확인 기능을 구비한 버터플라이 밸브 장치{Butterfly valve having function for sensing opening and closing status}Butterfly valve having function for opening and closing function {Butterfly valve having function for sensing opening and closing status}

이 발명은 밸브 분야에 관한 것으로서, 좀더 세부적으로 말하자면 기어박스와 밸브 디스크를 연결하는 연결축이 파손되는 경우에도 밸브 디스크의 개폐상태를 정확하게 확인할 수 있도록 하며,밸브를 분해하지 않고서도 밸브 내부의 개폐상태를 정확하게 확인할 수 있도록 함으로써 밸브와 연관된 설비의 고장을 미연에 방지할 수 있도록 하는, 개폐확인 기능을 구비한 버터플라이 밸브 장치에 관한 것이다.The present invention relates to the field of valves, and more specifically, to accurately check the opening and closing state of the valve disc even if the connecting shaft connecting the gearbox and the valve disc is broken, and to open and close the inside of the valve without disassembling the valve. The present invention relates to a butterfly valve device having an opening / closing check function, which makes it possible to accurately check a state, thereby preventing a failure of a facility associated with a valve.

버터플라이 밸브는 둥근 몸체 내부에 원반형의 디스크가 축에 조립되어 밸브의 유로를 개폐하는 밸브로서, 다음과 같이 분류된다.The butterfly valve is a valve in which a disc-shaped disc is assembled to the shaft in the round body to open and close the flow path of the valve, and is classified as follows.

먼저, 연결방식에 따라 웨이퍼형, 플랜지형, 소켓용접형으로 구분된다. 웨이퍼형은 플랜지와 플랜지 사이에 삽입하는 형식으로 밸브 몸통에는 플랜지가 없다. 플랜지형은 보통의 플랜지식 밸브와 같이 플랜지가 붙어있는 것으로 고기능성 버터플라이밸브에 많이 적용한다. 소켓용접형은 보통의 용접식 볼밸브 처럼 만들어지고 파이프를 양쪽에 삽입하여 용접한다.First, it is divided into wafer type, flange type, and socket welding type according to the connection method. Wafer type inserts between the flange and the flange, there is no flange on the valve body. Flange type is flanged like normal flanged valve and is applied to high performance butterfly valve. Socket welds are made like ordinary welded ball valves and welded by inserting pipes on both sides.

다음에는, 시트의 재질에 따라 고무시트형, 메탈시트형으로 구분된다. 고무 시트형은 보통 고무붙이시트형 버터플라이밸브라고 부르는 것으로 몸통의 내측이고무링 형태로 되어 있어 가장 널리 사용되며 주로 저압에 사용된다. 메탈시트형은 몸통의 내측에 탄성이 있는 금속의 원형 시트를 가진 밸브로 주로 고기능성의 편심형 버터플라이밸브에 많이 사용되며, 고압에 주로 사용된다. 기타 실리콘고무시트, 불소수지(테프론)시트 등이 있다.Next, it is divided into a rubber sheet type and a metal sheet type according to the material of the sheet. The rubber seat type is commonly referred to as the rubber seated butterfly valve and is the most widely used since it is in the inner ring of the body and is mainly used for low pressure. The metal seat type is a valve having a circular sheet of elastic metal inside the body, and is mainly used for a highly functional eccentric butterfly valve, and is mainly used for high pressure. Other silicone rubber sheets, fluororesin (teflon) sheet, and the like.

또한, 구동형식에 따라 레버식, 기어식, 실린더식, 모터식으로 구분된다. 레버식은 수동식의 기다란 레버를 90도 회전시켜 밸브를 개폐한다. 기어식은 워엄과 워엄기어로 구성되는 기어박스를 가지고 있고 핸드휠을 돌려 밸브를 개폐한다. 실린더식은 랙과 피니언으로 동작되는 단동 혹은 복동식의 에어 또는 유압실린더를 이용하여 밸브를 개폐한다. 모터식은 전동기를 이용하여 밸브를 개폐한다.In addition, it is classified into lever type, gear type, cylinder type and motor type according to the driving type. Lever type rotates the manual long lever 90 degrees to open and close the valve. The gear type has a gearbox consisting of worms and worm gears, and rotates the handwheel to open and close the valve. The cylinder type uses a single or double acting air or hydraulic cylinder operated by a rack and pinion to open and close the valve. The motor type opens and closes the valve using an electric motor.

그리고, 스템의 위치에 따라 동심형, 편심형으로 구분된다. 동심형은 밸브디스크와 연결된 축(스템)이 밸브 몸통의 중앙에 위치한 밸브로서, 주로 저압에 사용한다. 편심형은 밸브 스템이 밸브 몸통의 중앙에서 편심되는 위치에 있는 밸브로서 이중 또는 삼중편심형이 있다. And, depending on the position of the stem is divided into concentric and eccentric. The concentric valve is a valve in which the shaft connected to the valve disc is located at the center of the valve body, and is mainly used for low pressure. The eccentric type is a valve in which the valve stem is eccentric at the center of the valve body, which may be double or triple eccentric.

그러나, 상기한 바와 같은 버터플라이 밸브는, 외부에서 밸브의 개폐상태를 확인할 수가 없는 문제점이 있다.However, the butterfly valve as described above has a problem that the open / close state of the valve cannot be confirmed from the outside.

이러한 문제점을 해결하기 위한 것으로서, 작업자의 시야범위내에서 방향에 무관하게 항상 밸브의 개폐를 확인하기 용이하도록 하는 기술이 대한민국 등록실용신안공보 등록번호 20-0269034(공고일자 2002년 3월 21일)의 "버터플라이밸브의 개도상태 표시장치"에서 개시된 바 있다.In order to solve this problem, a technology that makes it easy to check the opening and closing of the valve at all times regardless of the direction of the operator within the field of view of the Republic of Korea Utility Model Publication No. 20-0269034 (announcement date March 21, 2002) It is disclosed in "opening state display device of the butterfly valve" of.

그러나, 이와 같은 종래의 등록번호 20-0269034는 기어박스와 밸브 디스크를 연결하는 연결축인 샤프트가 파손되는 경우에 표시창에는 정상적으로 개폐가 되는 것으로 표시되지만 실제로 밸브 내부의 밸브 디스크는 동작하지 않는 현상이 발생하게 되므로 외부에서 육안으로 밸브의 개폐여부를 정확하게 확인할 수 없게 되는 문제점이 있다.  However, the conventional registration number 20-0269034 shows that when the shaft, which is the connecting shaft connecting the gearbox and the valve disk, is normally opened and closed on the display window, the valve disc inside the valve does not operate. There is a problem that can not accurately check whether the valve is opened or closed with the naked eye from the outside.

도 1에 도시되어 있는 바와 같이, 이 발명의 일실시예에 따른 개폐확인 기능을 구비한 버터플라이 밸브 장치의 구성은, 사용자가 밸브를 개폐시키기 위한 회전조작을 하기 위한 조작핸들(1)과, 상기한 조작핸들(1)에 연결되어 있으며 조작핸들(1)로부터 발생된 회전력의 방향을 전환하여 전달하기 위한 기어박스(2)와, 상기한 기어박스(2)로부터 회전력을 밸브 디스크(6)로 전달하기 위한 연결축(5)과, 상기한 연결축(5)으로부터 전달되는 회전력에 의해 회전됨으로써 밸브를 개폐시키는 밸브 디스크(6)와, 상기한 밸브 디스크(6)를 설치하기 위한 밸브 바디(4)와, 상기한 밸브 디스크(6)의 일단에 설치되어 있는 영구자석(7)과, 상기한 영구자석(7)으로부터 발생되는 자력을 감지하기 위한 마그네틱 센서(8)와, 상기한 마그네틱 센서(8)에 연결되어 밸브 디시크(6)의 개폐상태를 외부에 표시하기 위한 지시계(3)를 포함하여 이루어진다.As shown in Figure 1, the configuration of the butterfly valve device having an opening and closing check function according to an embodiment of the present invention, the operation handle (1) for the user to rotate the operation for opening and closing the valve, The gear box 2 is connected to the operation handle 1 and transfers the rotational force from the gear box 2 to the gear box 2 for transferring the direction of rotation force generated from the operation handle 1 and the valve disc 6. A valve body 6 for installing the valve disc 6 and a valve disc 6 for opening and closing the valve by being rotated by the rotational force transmitted from the connecting shaft 5, the valve shaft 6 for transmitting the valve shaft 6. (4), a permanent magnet (7) provided at one end of the valve disc (6), a magnetic sensor (8) for detecting a magnetic force generated from the permanent magnet (7), and the magnetic described above. Connected to the sensor (8) to the valve disc (6) It comprises the indicator (3) for displaying the closed state to the outside.

상기한 기어박스(2)는 기어들의 조합으로 이루어진다.The gearbox 2 is made of a combination of gears.

상기한 지시계(3)는 램프 또는 발광다이오드로 이루어진다.The indicator 3 consists of a lamp or a light emitting diode.

상기한 구성에 의한, 이 발명의 일실시예에 따른 개폐확인 기능을 구비한 버터플라이 밸브 장치의 작용은 다음과 같다.According to the above configuration, the operation of the butterfly valve device with an opening and closing confirmation function according to an embodiment of the present invention is as follows.

사용자가 조작핸들(1)을 회전시키면, 기어박스(2)에 의해 회전동력이 방향을 바꾸어 전달되고, 연결축(5)에 의해 밸브 디스크(6)로 전달됨으로써 밸브 디스크(6)가 회전하게 됨으로써 밸브가 개폐된다.When the user rotates the operation handle 1, the rotational power is transmitted by changing the direction by the gear box 2, and the valve disk 6 is rotated by being transmitted to the valve disk 6 by the connecting shaft (5). As a result, the valve is opened and closed.

밸브 디스크(6)가 회전하여 밸브를 닫게 되면 밸브 디스크(6)에 설치된 영구자석(7)이 마그네틱 센서(8)와 최단거리에 위치하게 됨에 따라 마그네틱 센서(8)가 영구자석(7)의 자력을 감지하여 지시계(3)인 램프가 점등된다.

By detecting the magnetic force, the lamp which is the indicator 3 lights up.

밸브 디스크(6)가 회전하여 밸브를 열게 되면 밸브 디스크(6)에 설치된 영구자석(7)이 마그네틱 센서(8)와 최장거리에 위치하게 됨에 따라 마그네틱 센서(8)가 영구자석(7)의 자력을 감지하지 못하게 됨에 따라 지시계(3)인 램프가 점멸된다. When the valve disc 6 rotates to open the valve, the permanent magnet 7 installed in the valve disc 6 is positioned at the longest distance from the magnetic sensor 8, so that the magnetic sensor 8 is connected to the permanent magnet 7. The lamp, which is the indicator 3, flashes as the magnetic force cannot be detected.

만약 연결축(5)이 파손되더라도, 마그네틱 센서(8)는 영구자석(7)의 위치에 따라 즉 밸브 디스크(6)의 개폐상태를 정확하게 감지하게 됨으로써 외부에서 육안으로 밸브 개폐여부를 확인할 수 있 된다.If the connecting shaft 5 is broken, the magnetic sensor 8 can accurately check the opening and closing state of the valve disc 6 according to the position of the permanent magnet 7, so that the valve can be visually checked from the outside. do.
