[문헌 2] 한국특허등록 등록번호 제10-0632972호, 2006.09.29[Document 2] Korean Patent Registration No. 10-0632972, 2006.09.29

플러그 밸브는 유체의 출입구가 형성된 본체와, 본체에 삽입되어 유체를 단속하는 플러그로 구성된다. 상기의 플러그는 원통면으로 형성되어 있고, 이와 접촉되는 본체 부분도 같은 곡률을 가진 원통면의 형상으로 되어 있다.The plug valve is composed of a main body in which a fluid inlet and outlet is formed, and a plug inserted into the main body to control the fluid. The said plug is formed in the cylindrical surface, and the main-body part contacted with it is also the shape of the cylindrical surface which has the same curvature.

따라서 종래의 경우는 플러그의 곡면을 본체의 접촉면과 같이 가공하는 것이 어려워 완전한 유체의 단속이 어려웠다. 그리고 본체를 원통형의 플러그에 맞도록 가공하는 것 또한 어려운 일이었다.Therefore, in the conventional case, it is difficult to process the curved surface of the plug like the contact surface of the main body, which makes it difficult to interrupt the complete fluid. It was also difficult to machine the body to fit the cylindrical plug.

종래의 문제점을 해소하기 위한 본 발명은 본체가 구의 형상을 가지고, 플러그는 원판 디스크의 형상으로 되어, 본체는 수직으로 절단되어 원형의 개구부가 용이하게 형성되고, 이에 볼 형의 플러그가 개폐되게 설치된 구조를 제공하게 된다.According to the present invention for solving the conventional problems, the main body has a spherical shape, the plug is in the shape of a disc, the main body is vertically cut to facilitate the circular opening, the ball-type plug is installed to open and close To provide a structure.

본 발명의 원판 볼타입 편심 플러그 밸브는 플러그가 편심되게 설치되어 닫힐 때 편심 회전축에 의해 본체시트와 마찰없이 작동하되 완전 밀착되어 누수가 없고, 구형의 본체를 절단하면 완전한 형상의 원형 개구부가 형성되므로 본체의 제작이 용이하며, 또한 플러그는 원판형이므로 이 또한 제작이 용이한 장점을 가진다.Disc ball type eccentric plug valve of the present invention operates without friction with the main body seat by the eccentric rotation shaft when the plug is installed eccentrically closed, so that there is no water leakage, cutting the spherical body, so that the circular opening of a perfect shape is formed The production of the main body is easy, and since the plug is disc-shaped, this also has the advantage of easy manufacturing.

본 발명은 일측에 유입구(1)가 형성되고, 타측에 원형의 유출구(2)가 형성되며, 구형(求刑)으로 된 본체(3)와; 상하부에 형성된 스탬(4)과 회동축(5)이 본체(3)에 지지되어 상기 유출구(2)를 개폐하는 원판 디스크 형상의 플러그(6)와; 상기 본체(3)의 유출구(2)측에 결합되고, 플러그(6)가 안착되는 본체시트(7)가 설치된 유출관(8);을 포함하여 구성된다.The present invention is an inlet (1) is formed on one side, a circular outlet (2) is formed on the other side, the body (3) made of a spherical shape; A disk disk-shaped plug 6 supporting the stem 4 and the rotation shaft 5 formed on the upper and lower parts of the main body 3 to open and close the outlet 2; And an outlet pipe 8 coupled to the outlet 2 side of the body 3 and provided with a body sheet 7 on which the plug 6 is seated.

상기의 플러그(6)는 작동에 있어 용이함을 위하여 회동축(5)이 지지되는 본체(3) 부분에 축지부(9)가 설치되고, 축지부(9)에는 회동축(5)이 삽입되는 부시(10)가 삽입설치된다.The plug 6 is provided with a bearing portion 9 in the main body portion 3, the rotation shaft 5 is supported for ease of operation, the rotation shaft 5 is inserted into the bearing portion 9 Bush 10 is inserted.

그리고 본체(3)의 상부에는 플러그(6)의 본체내 설치를 용이하게 하고, 스탬(4)을 지지하는 보닛(11)이 설치된다.In addition, a bonnet 11 for facilitating installation in the main body of the plug 6 and supporting the stem 4 is provided on the upper part of the main body 3.

또한 플러그(6)의 회동축(5)은 본체(3)의 유입구(1)와 유출구(2)가 형성하는 중심축에서 일정 거리 이격되게 편심되도록 설치된다.In addition, the rotation shaft 5 of the plug 6 is installed to be eccentrically spaced apart from the central axis formed by the inlet 1 and the outlet 2 of the main body 3.

이와 같은 구조의 본 발명은 플러그(6)가 원판형의 디스크인 것에 큰 특징이 있다. 따라서 플러그(6)의 제작이 종래에 비하여 용이하고, 플러그(6)가 개폐하는 본체(3)의 유출구(2)의 형상 또한 원형으로 용이하게 형성시킬 수 있으며, 이는 본체(3)가 구형으로 형성되어 있어 더욱더 용이하게 된다.The present invention having such a structure is characterized in that the plug 6 is a disk-shaped disk. Therefore, the manufacture of the plug 6 is easier than in the prior art, and the shape of the outlet 2 of the main body 3 in which the plug 6 is opened and closed can also be easily formed in a circular shape, which means that the main body 3 is spherical. Formed so that it becomes easier.

상기 구조를 가진 본 발명의 작동은 플러그(6)를 회동시켜 유체를 개폐함으로 이루어진다. 도 3과 도 4에 도시된 바와 같이 플러그(6)의 회동축(5)은 본체(3)의 중심에서 편심되어 있어, 개폐 작동에 있어서 플러그(6) 반경이 증가되어 본체 시트(7)와의 마찰이 없어 본체시트(7)의 손상이 없게 된다. 그리고 편심에 의하여 토오크를 작게하여 작동시킬 수 있어 동력이 절감된다.The operation of the present invention having the above structure is achieved by opening and closing the fluid by rotating the plug 6. As shown in Figs. 3 and 4, the pivot shaft 5 of the plug 6 is eccentric at the center of the main body 3, so that the radius of the plug 6 is increased in the opening and closing operation so that There is no friction so that the body sheet 7 is not damaged. In addition, the torque is reduced by the eccentricity can be operated to save power.

그리고 본 발명은 도 4에 도시된 이점 쇄선의 상태로 플러그(6)가 회동되었을 때, 밸브가 완전 열림이 되고, 이 때 밸브 유로 단면적에 대해 유과경이 100％ 확보되어 밸브 내에서 유체가 통과할 때 와류 및 압력손실이 발생하지 않게 된다. 즉, 플러그(6)가 본체(3) 유로에서 완전히 벗어나므로 유체저항이 적고 압력손실이 적어진다.In the present invention, the valve is fully opened when the plug 6 is rotated in the state of the advantage chain shown in Fig. 4, and at this time, the flow passage is secured 100% with respect to the cross-sectional area of the valve flow path to allow fluid to pass through the valve. At the same time, no vortex and pressure loss occur. That is, since the plug 6 is completely out of the main body 3 flow path, the fluid resistance is low and the pressure loss is small.

또한 본 발명은 본체(3)와 유출관(8)이 결합 구조로 되어 있고, 플러그(6)는 본체(3)에 설치되는 보닛(11)에 의해 본체(3)의 내부로 자유롭게 출납이 가능하므로, 배관에서 탈거하여 벨브를 유지보수하는 등의 불편함이 해소된다.In addition, according to the present invention, the main body 3 and the outlet pipe 8 are coupled to each other, and the plug 6 can be freely inserted into and taken out of the main body 3 by the bonnet 11 installed on the main body 3. Therefore, the inconvenience of maintaining the valve by removing it from the pipe is eliminated.

따라서 본 발명은 유체의 흐름이나 주위환경에 상관없이 수직형이고, 설치가 간단하며, 플러그(6)가 유로에서 벗어나 유체저항이 없다.Therefore, the present invention is vertical, irrespective of the flow of the fluid and the surrounding environment, and the plug 6 is free from the flow path and there is no fluid resistance.
