It is related to a line contact triple eccentric butterfly valve that prevents leakage during the opening and closing as well as minimizing the frictional loss by opening and closing through.
일반적으로 버터플라이밸브는, 수직형과 수평형 구조가 있으며, 이들은 통상 도 1 또는 도 2에 도시된 바와같이 유로홀을 갖는 밸브몸체(10), 밸브몸체(10)의 유로홀을 개폐하게 되는 밸브디스크(20), 밸브디스크(20)를 회전시키는 밸브축(30), 이 밸브축(30)을 조작하는 조작부(40)로 구성되어 밸브축(40)의 회전에 따른 밸브디스크(20)의 회전으로 유로를 개폐하게 된다.In general, a butterfly valve has a vertical type and a horizontal type, and these valve valves 10 normally open and close the flow path of the valve body 10 and the valve body 10 as shown in FIG. 1 or 2. The valve disk 20, the valve shaft 30 for rotating the valve disk 20, and the operation unit 40 for operating the valve shaft 30, the valve disk 20 according to the rotation of the valve shaft 40 The flow path is opened and closed by the rotation of.
최근에는 안정된 기밀 유지를 위해 3중 편심형 버터플라이밸브가 주로 적용되고 있으며, 여기서 3중 편심이라함은 도 3에 도시된 바와같이 유로를 개폐하는 밸브디스크(20)를 밸브몸체(10)의 수직선의 중심으로부터 "1"만큼 좌측 또는 우측으로 편심시킨 것을 1차 편심이라 하고, 상기 밸브디스크(20)를 회전시키는 회전축인 밸브축(30)이 밸브몸체(10)의 수평선과 수직선의 중심으로부터 "2"만큼 편심시킨 것을 2차편심이라 하며, 상기 밸브몸체(10)의 유로홀 내벽에 조립된 금속시트와 밸브디스크(20)에 조립된 금속시트가 맞닿는 끝점을 기준으로 하여 한쪽 콘의 기준선을 수평으로 한 것을 3차 편심이라 하여 이들을 3중 편심형 버터플라이밸브라 한다.Recently, a triple eccentric butterfly valve is mainly applied to maintain a stable airtight, wherein the triple eccentric butterfly valve is a valve disc 20 for opening and closing a flow path as shown in FIG. 3 of the valve body 10. Eccentricity of the left or right eccentric by "1" from the center of the vertical line is called primary eccentricity, and the valve shaft 30, which is a rotation shaft for rotating the valve disc 20, is formed from the center of the horizontal line and the vertical line of the valve body 10. The eccentric by "2" is called the secondary eccentric, and the reference line of one cone on the basis of the end point where the metal sheet assembled on the inner wall of the flow path of the valve body 10 and the metal sheet assembled on the valve disc 20 meet. This is called the third eccentric, and these are called triple eccentric butterfly valves.
하지만, 밸브디스크에 제공되는 시트가 밸브몸체에 제공되는 시트와의 접촉시 스프링식(패드) 탄성 구조의 경우 시트의 탄성력 발생으로 접촉시 마찰손실로 조작 토크가 크게 발생되는 문제점이 있어왔고, 또한 일반적인 구조의 경우 밸브디스크의 개폐시 시트와 시트의 전면 접촉으로 인하여 개폐시에 진공력이 발생 또는 접촉면적으로 마찰 손실이 많게 되는 문제점이 있다.However, in the case of the spring-type (pad) elastic structure when the seat provided on the valve disc is in contact with the seat provided on the valve body, there is a problem in that the operation torque is largely generated due to friction loss when the contact occurs due to the elastic force of the seat. In the case of the general structure, there is a problem in that a vacuum force is generated or a frictional loss is large in the contact area due to the front contact between the seat and the seat when opening and closing the valve disc.
또한, 시트는 금속의 박판이 여러층으로 적층 결합되는 것이어서 유로에 고압이 발생되는 경우 그 압력으로 인한 변형으로 누수 현상이 발생되는 문제점이 있어 일반적인 유류 등에는 적합할 수 있지만 음용수로는 부적합하게 되는 문제점이 있어왔다.In addition, the sheet is a thin metal plate is laminated and bonded in multiple layers, so that when the high pressure is generated in the flow path, there is a problem in which water leakage occurs due to the deformation caused by the pressure, but may be suitable for general oil, etc., but is not suitable for drinking water. There has been a problem.
이에, 본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로, 본 고안의 목적은 3중 편심형 버터플라이밸브에서 유로를 개폐하는 밸브디스크와 이 밸브디스크가 설치되는 밸브몸체의 유로홀 내벽을 개선하여 회전되는 밸브디스크가 유로홀 내벽과 선접촉을 통해 유로홀을 개폐할 수 있도록 하는데 있는 것이다.Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to improve a valve disk for opening and closing a flow path in a triple eccentric butterfly valve and an inner wall of the flow path of the valve body in which the valve disk is installed.

그리고, 상기 금속시트(300)의 접촉면에 파형으로 된 굴곡라인(100)이 테두리면을 따라 형성되어 접촉시 다수개의 선접촉 라인을 가지며 접촉된다.In addition, the curved curved line 100 on the contact surface of the metal sheet 300 is formed along the rim surface and is in contact with a plurality of line contact lines.
상기 굴곡라인(100)은, 3중 편심형 버터플라이밸브(종래기술 도3에 도시)에 적용되는 것으로 상기 밸브몸체(10)에 형성된 금속시트(200)는 콘 형상을 가지되, 상기 밸브디스크(20)의 유로 이동방향 전후측 일점을 수평 기준점으로 하여 콘 형상을 가지도록 형성된 것이다. 이에따라 금속시트(200)의 내주면은 일점을 기준으로 하여 그 둘레를 따라 그 경사각이 점차적으로 크게 형성된다. 즉, 상기 굴곡라인(100)은 바람직하게 도 3에 도시된 상기 금속시트(200)(300) 중 상기 금속시트(200)에 접하는 상기 금속시트(300)의 접촉면에 형성되는 것으로 그 상측 접촉면은 수평으로 하측은 오른쪽 하향의 경사각을 가지며 형성된다. 다시말해 상기 금속시트(200)에 밸브디스크(20)의 금속시트(300)가 접촉되는 것이고, 이 금속시트(300)에 파형으로된 굴곡라인(100)이 테두리를 따라 형성된다. The bending line 100 is applied to a triple eccentric butterfly valve (as shown in FIG. 3 of the related art), and the metal seat 200 formed on the valve body 10 has a cone shape, but the valve disc It is formed so as to have a cone shape with one point before and after the flow path movement direction of 20 as a horizontal reference point.
