1 : 직선몸체시트면1: Straight body sheet surface

2 : 직선디스크시트면2: straight disc seat surface

본 고안은 버터플라이밸브에 관한 것으로 상세하게는 디스크 가장자리의 디스크시트면과 몸체의 유로 가장자리에 형성된 몸체시트면 사이의 접촉면적을 넓힘 으로서 정압은 물론 역압에서도 유로를 긴밀하게 밀폐시킬 수 있게 한 역압에 의한 누수를 방지한 버터플라이밸브에 관한 것이다. The present invention relates to a butterfly valve, and in particular, the contact pressure between the disk seat surface of the disk edge and the body seat surface formed on the edge of the flow path of the body increases the back pressure that allows the flow path to be tightly sealed at both the positive pressure and the reverse pressure. The present invention relates to a butterfly valve that prevents leakage by water.

일반적으로 버터플라이밸브는 유체가 통과되는 관 사이에 장착되어 이동되는 유체를 단속하거나 유체량을 가변시키는 수단으로 사용되는 것이다. In general, a butterfly valve is used as a means for controlling a fluid or varying the amount of fluid that is mounted between pipes through which fluid passes.

이러한 버터플라이밸브의 일예를 도 3에 개략적으로 도시하였다. An example of such a butterfly valve is schematically illustrated in FIG. 3.

도시한 바와 같이 버터플라이밸브는 유로(100a)가 형성된 몸체(100)를 수직으로 관통하여 설치된 회전축(300)에 디스크(200)를 설치하고, 회전축(300)에는 작동손잡이(400)를 설치하여 회전축(300)을 회전시켜 디스크(200)를 회전시킴으로서 유로(100a)가 개폐되도록 구성되어 있다. As shown in the butterfly valve, the disk 200 is installed on the rotating shaft 300 installed vertically through the body 100 in which the flow path 100a is formed, and the operating handle 400 is installed on the rotating shaft 300. By rotating the rotating shaft 300 to rotate the disk 200 is configured to open and close the flow path (100a).

이렇게 구성된 버터플라이밸브는 디스크(200)의 가장자리의 디스크시트면(210)과 몸체(100)에 형성된 유로(100a)의 가장자리에 형성된 몸체시트면(110)이 서로 접촉됨에 유로가 폐쇄되고, 서로 멀어짐에 의해 유로가 개방된다. The butterfly valve configured as described above has a flow path closed because the disk seat surface 210 at the edge of the disk 200 and the body seat surface 110 formed at the edge of the flow path 100a formed at the body 100 are in contact with each other. The flow path is opened by moving away.

이렇게 구성된 종래의 버터플라이밸브의 디스크시트면(210)은 도 4에 도시한 바와 같이 그 단면이 호 형상으로 형성되고, 몸체시트면(110)은 직선으로 형성되어 있어서 호형상의 디스크시트면(210)의 어느 한 부분이 몸체시트면(110)의 어느 한부분에 접촉됨에 의해 유로가 폐쇄되게 구성되어 있다. The disk seat surface 210 of the conventional butterfly valve configured as described above is formed in an arc shape as shown in FIG. 4, and the body seat surface 110 is formed in a straight line to form an arc-shaped disk seat surface ( Any portion of the 210 is in contact with any portion of the body seat surface 110 is configured to close the flow path.

이렇게 구성된 버터플라이밸브의 시트면(110, 210)은 두 시트면(110, 210)이 접촉될 수 있는 부분은 넓으나 실제로 접촉되는 부분은 선형으로 좁아 정압이 작용할 때에 즉, 도 4에서 유체의 흐름이 우측으로 향할 때에는 유체에 의해 디스크(200)가 우측으로 밀려 시트면(110, 210)사이의 접촉이 긴밀해져 유체의 누출이 이루어지지 않으나, 역압 즉, 도 4에서 유체의 흐름이 좌측을 향할 때에는 유체의 압력에 의해 디스크(200)가 좌측으로 밀려 시트면(110, 210) 사이에 틈이 발생하여 유체의 누출이 발생하는 문제가 있었다. The seat surfaces 110 and 210 of the butterfly valve configured as described above have a wide area where the two seat surfaces 110 and 210 can be contacted, but a part which is actually contacted is linearly narrow, so that when the positive pressure is applied, that is, the fluid of FIG. When the flow is directed to the right side, the disk 200 is pushed to the right by the fluid, so that the contact between the seat surfaces 110 and 210 is intimate, so that no leakage of the fluid occurs. When facing, the disk 200 is pushed to the left side by the pressure of the fluid, a gap is generated between the seat surfaces (110, 210), there is a problem that the fluid leaks.

본 고안은 위와 같은 문제점을 해결하기 고안된 것으로, 시트면 사이의 접촉면적을 넓힘으로서 정압에서는 물론 역압에서도 유로를 밀폐시킬 수 있게 한 역압에 의한 누수를 방지한 버터플라이밸브를 제공하는 것을 목적으로 한다. The present invention was devised to solve the above problems, and an object of the present invention is to provide a butterfly valve which prevents leakage due to reverse pressure, which allows the flow path to be sealed at both positive and reverse pressure by widening the contact area between the seat surfaces. .

상기 목적을 달성하기 위한 본 고안에 따른 역압에 의한 누수를 방지한 버터플라이밸브는 유로가 관통하여 형성된 몸체와, 상기 유로의 내부에 회전 가능가게 설치된 디스크와, 상기 몸체를 관통하여 유로의 내부까지 연장된 단부에 상기 디스크가 고정 설치된 회전축을 포함하여 구성된 버터플라이밸브에 있어서, 상기 몸체에 형성된 유로의 일측 가장자리에 직선형으로 형성된 직선몸체시트면과 ; 상기 디스크의 가장자리에 직선형으로 형성된 직선디스크시트면을 포함함을 특징으로 한다. The butterfly valve which prevents the leakage by the back pressure according to the present invention for achieving the above object is a body formed through the flow path, a disk rotatably installed in the inside of the flow path, and through the body to the inside of the flow path A butterfly valve comprising a rotating shaft having the disk fixed to an extended end, the butterfly valve comprising: a straight body seat surface formed in a straight line at one edge of a flow path formed in the body; It characterized in that it comprises a straight disk sheet surface formed in a straight line on the edge of the disk.

이하에서는 첨부된 도면을 참조하여 기술되는 바람직한 실시예를 통하여 본 고안을 당업자가 용이하게 이해하고 재현할 수 있도록 상세히 기술하기로 한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

도 1은 본 고안에 따른 버터플라이밸브의 시트면이 서로 이격된 상태를 확대하여 도시한 부분단면도이고, 도 2는 본 고안에 따른 버터플라이밸브의 시트면이 서로 접촉된 상태를 확대하여 도시한 부분단면도이다. 1 is an enlarged partial cross-sectional view showing a state in which the seat surface of the butterfly valve according to the present invention spaced apart from each other, Figure 2 is shown in an enlarged state of the seat surface of the butterfly valve according to the present invention in contact with each other Partial section view.

도시한 바와 같이 본 고안에 따른 버터플라이밸브는 몸체(100)에 형성된 시트면과 디스크에 형성된 시트면이 직선형을 이룸을 특징으로 한다. As shown, the butterfly valve according to the present invention is characterized in that the seat surface formed on the body 100 and the seat surface formed on the disk form a straight line.

즉, 본 고안에 따른 역압에 의한 누수를 방지한 버터플라이밸브는 몸체(100)에 형성된 유로의 일측 가장자리에 직선형으로 형성된 직선몸체시트면(1)과 ; 상기 디스크(200)의 가장자리에 직선형으로 형성된 직선디스크시트면(2)을 포함하여 구성된다. That is, the butterfly valve to prevent leakage by the back pressure according to the present invention is a straight body seat surface (1) formed in a straight line on one side edge of the flow path formed in the body 100; It comprises a straight disk sheet surface 2 formed in a straight line at the edge of the disk 200.

이렇게 직선형의 직선몸체시트면(1)과 직선디스크시트면(2)을 갖는 버터플라이밸브의 다른 부분의 구성은 종래의 버터플라이밸브의 구성과 동일 또는 유사함으로 이에 대한 상세한 설명은 생략한다. Since the configuration of the other parts of the butterfly valve having the straight linear body seat surface 1 and the straight disk seat surface 2 is the same as or similar to that of the conventional butterfly valve, a detailed description thereof will be omitted.

상기 직선몸체시트면(1)은 도 3에 도시한 바와 같이 몸체(100)를 관통하여 형성된 유로(100a)의 일측 단부의 내주면에 형성되고, 도 1 및 도 2에 도시한 바와 같이 직선형으로 형성되어 있다. The straight body sheet surface 1 is formed on the inner circumferential surface of one end of the flow path 100a formed through the body 100 as shown in FIG. 3, and is formed in a straight line as shown in FIGS. 1 and 2. It is.

이렇게 형성된 직선몸체시트면(1)과 대향되는 직선디스크시트면(2)은 디스크(200)의 가장자리에 형성되고, 역시 직선으로 구성된다. The straight disk sheet surface 2 opposed to the straight body sheet surface 1 thus formed is formed at the edge of the disk 200 and is also composed of straight lines.

상기 직선몸체시트면(1)과 직선디스크시트면(2)은 통상적인 버터플라이밸브에 형성된 시트면과 동일 또는 유사하게 경사지게 형성하여 디스크(200)의 회전에 의해 유로가 개폐될 때 용이하게 두 면이 접촉될 수 있게 하였으며, 이 경사의 각도 등은 기존의 버터플라이밸브에 형성된 시트면의 경사각과 동일 유사하다. The straight body seat surface (1) and the straight disk seat surface (2) is formed to be inclined in the same or similar to the seat surface formed in a conventional butterfly valve to facilitate the opening and closing of the flow path by the rotation of the disk (200) The surface can be contacted, and the inclination angle and the like are the same as the inclination angle of the seat surface formed in the conventional butterfly valve.

상기 직선몸체시트면(1)과 직선디스크시트면(2)이 전체적으로 접촉될 수 있으나 이렇게 접촉되는 면적이 넓으면 접촉된 상태에서 분리될 때 분리가 잘 이루어 지지 않을 수 있으므로 접촉면적을 너무 넓게 형성하지 않는 것이 바람직하다. The linear body sheet surface 1 and the linear disk sheet surface 2 may be in contact as a whole, but if the contact area is wide, the contact area may be made too wide since the separation may not be performed well when separated in contact. It is desirable not to.

따라서 상기 직선몸체시트면(1)의 폭은 직선디스크시트면(2)의 폭보다 좁게 형성한다. Therefore, the width of the linear body sheet surface 1 is formed to be narrower than the width of the linear disk sheet surface (2).

즉, 도 1 및 도 2에 도시한 바와 같이 몸체(100)에 형성된 유로의 일측에 형성된 시트면이 형성되는 부분의 일측에 홈을 형성하여 실제로 디스크(200)에 형성된 직선디스크시트면(2)과 접촉되는 직선몸체시트면(1)의 폭은 좁게 형성하였다. That is, as illustrated in FIGS. 1 and 2, a groove is formed on one side of a portion where the sheet surface formed on one side of the flow path formed in the body 100 is formed, and thus the straight disk sheet surface 2 actually formed on the disk 200. The width of the linear body sheet surface 1 in contact with the formed narrow.

이렇게 몸체(100)에 형성된 상기 직선몸체시트면(1)과 직선디스크시트면(2)의 접촉 면적이 넓게 형성됨으로서 역압에 디스크(200)에 역압이 작용하여도 디스크(200)가 밀려도 직선몸체시트면(1)과 직선디스크시트면(2)이 접촉되는 부분이 남아 있게 되어 유체가 누출되지 않게 된다. Thus, the contact area between the linear body sheet surface 1 and the linear disk sheet surface 2 formed in the body 100 is formed to be wide, so that even if the disk 200 is pushed even when the disk 200 is pushed against the reverse pressure, The part where the body seat surface 1 and the straight disk seat surface 2 contact remains, so that the fluid does not leak.

상기 디스크(200)의 경우 강도가 강하고 부식이 적은 스테인레스강 등으로 만들어지고, 몸체(100)의 경우에는 주물로 만들어지나 몸체에 형성된 직선몸체시트면(1)은 열처리를 하여 강도를 높이거나 스테인레스강으로 형성함이 바람직하다. In the case of the disk 200 is made of stainless steel, such as high strength and less corrosion, the body 100 is made of cast, but the straight body sheet surface (1) formed on the body is heat treated to increase the strength or stainless steel It is preferable to form with steel.

이렇게 상기 직선몸체시트면(1)과 직선디스크시트면(2)을 강도가 강하여 내마모성이 좋고 부식에 강하게 제작함으로서 작은 개폐 동작에 의해서도 직선몸체시트면(1)과 직선디스크시트면(2)이 마모되어 두 면 사이에 틈이 생기는 것을 방지할 수 있다. Thus, the straight body sheet surface 1 and the straight disk sheet surface 2 have high strength and wear resistance and are strong against corrosion, so that the straight body sheet surface 1 and the straight disk sheet surface 2 can be made even by a small opening and closing operation. It can be worn to prevent gaps between the two sides.

미설명부호 11은 직선몸체시트면(1)이 형성된 부분을 상기한 바와 같이 열처리 또는 고강도 재료로 형성한 것을 표시하기 위한 것이다. Reference numeral 11 is for indicating that the portion where the linear body sheet surface 1 is formed is formed of a heat treatment or a high strength material as described above.

이상에서 상세히 기술한 바와 같이, 본 고안은 몸체의 유로 가장자리에 형성된 몸체시트면과 디스크의 가장자리에 형성된 몸체시트면을 직선형으로 형성하여 두 시트면 사이의 접촉면적을 넓힘으로서 정압에서는 물론 역압에서도 유로를 밀폐시킬 수 있는 효과가 있다. As described in detail above, the present invention forms a body sheet surface formed at the edge of the flow path of the body and the body sheet surface formed at the edge of the disk in a straight line to widen the contact area between the two sheet surfaces, so that the flow path at the positive pressure as well as the reverse pressure There is an effect that can be sealed.

본 고안은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지만 당업자라면 이러한 기재로부터 본 고안의 범주를 벗어남이 없이 많은 다양한 자명한 변형이 가능하다는 것은 명백하다. 따라서 본 고안은 첨부된 청구범위의 문언에 의해서만 제한 해석될 수 있다. Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the present invention from this description. Therefore, the present invention may be construed limited only by the words of the appended claims.
