밸브는 유체를 통과시키거나 막거나, 제어하기 위하여 밸브 몸통 내에 형성된 통로를 개폐할 수 있는 가동기구가 설치된 기기의 총칭으로서 사용 목적에 따라 다양한 형식의 밸브가 사용되고 있으며, 밸브 몸통 내에 가동기구를 설치하기 위하여 밸브 몸통에 가동기구설치구를 형성하고 보닛을 사용하여 밀봉할 수 있게 구성된 밸브 형식이 있다.The valve is a generic term for a device equipped with a movable mechanism capable of opening and closing a passage formed in the valve body for passing, blocking, or controlling a fluid. Various types of valves are used according to the purpose of use, and a movable mechanism is installed in the valve body. To this end, there is a type of valve configured to form a movable mechanism installation in the valve body and to seal using a bonnet.

상기 보닛에는 가동기구를 작동시켜 밸브 몸통 내의 유체흐름을 막거나 통하게 하거나 제어할 수 있는 밸브대가 설치될 수 있다.The bonnet may be provided with a valve seat for operating the movable mechanism to block, allow or control the flow of fluid in the valve body.

상기한 바와 같은 형식의 밸브의 구체적 예로서 글로브 형(globe type) 밸브와 앵글 형(angle type) 밸브가 있다.Specific examples of valves of the type described above include globe type valves and angle type valves.

일반적으로 글로브 형 밸브는 입구와 출구의 유로가 S자 모양이며 외형이 공모양인 밸브 몸통의 형식을 지닌 밸브이며, 앵글 형 밸브는 입구와 출구의 유로가 직각인 밸브 몸통의 형식을 지닌 밸브이다.In general, the globe valve is a valve in the form of a valve body with the inlet and outlet flow paths having an S-shape and a ball shape, and the angle valve is a valve having a valve body in which the flow paths of the inlet and outlet are perpendicular to each other.

상기 글로브 형 밸브와 앵글 형 밸브는 디스크가 밸브대의 일측 끝에 설치되어 밸브대와 같은 방향으로 왕복직선운동이 가능케 구성되어 밸브 내에 형성된 유로를 개폐할 수 있게 구성된 밸브이다.The globe-type valve and the angle-type valve is a valve configured to enable the opening and closing of the flow path formed in the valve is configured to enable the reciprocating linear motion in the same direction as the valve stem is installed at one end of the valve stem.

The bonnet may be provided with a valve seat for operating the movable mechanism to block, direct or control the flow of fluid in the valve body. As a specific example of such a valve, a globe valve and an angle valve may be installed. type) There is a valve. In general, the globe valve is a valve in the form of a valve body with the inlet and outlet flow paths having an S-shape and a ball shape, and the angle valve is a valve having a valve body in which the flow paths of the inlet and outlet are perpendicular to each other.

상기 글로브 형 밸브와 앵글 형 밸브는 디스크가 밸브대의 일측 끝에 설치되어 밸브대와 같은 방향으로 왕복직선운동이 가능케 구성되어 밸브 내에 형성된 유로를 개폐할 수 있게 구성된 밸브이다.The globe-type valve and the angle-type valve is a valve configured to enable the opening and closing of the flow path formed in the valve is configured to enable the reciprocating linear motion in the same direction as the valve stem is installed at one end of the valve stem.

상기 글로브 형 밸브와 앵글 형 밸브와 같이 디스크가 밸브대의 직선왕복운동으로 이동되어 밸브 몸통 내에 구성된 밸브 시트에 밀착하여 유로를 개폐하는 종래의 밸브는 일반적으로 디스크의 가장자리에 패킹설치홈을 형성하여 설치된 패킹이 밸브 시트에 밀착하여 개폐기능을 수행하게 구성되어 있다.Conventional valves, such as globe valves and angle valves, which move discs in a straight reciprocating motion of valve stems to be in close contact with valve seats formed in the valve body, to open and close flow paths, are generally formed by forming packing installation grooves at the edges of the discs. The packing is configured to be in close contact with the valve seat to perform the opening and closing function.

그러나, 상기한 바와 같이 디스크의 가장자리에 설치된 패킹이 밸브 시트와 밀착되어 개폐기능을 수행하게 구성된 종래의 밸브는, 합성수지재로 제작된 패킹을 사용하는 경우 장기간 사용하면 패킹의 탄성력이 저하되어 유체가 새는 경향이 있었으며, 고온에서는 패킹이 녹아내려 개폐기능을 상실할 수 있어서 소방관련 배관에 사용하기 어려운 문제가 있었다.However, in the conventional valve configured to perform the opening and closing function of the packing is installed on the edge of the disk in close contact with the valve seat, when using a packing made of synthetic resin material, the elastic force of the packing is lowered when used for a long time, the fluid is There was a tendency to leak, and at high temperatures, the packing melted and lost its opening and closing function, making it difficult to use in fire-related piping.

상기 문제를 해결하기 위한 본 발명의 밸브 시트와 디스크의 실링 구조는, 밸브 몸통에 형성된 밸브 가동 기구 설치구에 보닛이 설치되고 상기 보닛에 설치된 밸브대의 직선왕복운동에 따라 디스크가 밸브대와 같은 방향으로 이동하여 밸브 시트에 밀착 가능케 구성되어 개폐기능을 수행하게 구성된 밸브에 있어서, 상기 디스크의 가장자리에 형성된 패킹설치홈에 패킹을 설치하여 밸브 시트에 밀착하여 개폐기능을 수행하게 구성되며, 상기 패킹설치홈을 이루는 테두리부 중에 바깥쪽 테두리부에 실링면을 형성하여 밸브 시트와 밀착되게 구성하여 이중으로 개폐기능을 수행하게 구성된 밸브 시트와 디스크의 실링 구조이다.In the sealing structure of the valve seat and the disk of the present invention for solving the above problems, the bonnet is installed in the valve actuating mechanism mounting hole formed in the valve body and the disk is in the same direction as the valve stem according to the linear reciprocating motion of the valve seat installed on the bonnet. In the valve configured to be close to the valve seat to perform the opening and closing function, the packing is installed in the packing installation groove formed on the edge of the disk to be in close contact with the valve seat is configured to perform the opening and closing function, the packing installation It is a sealing structure of the valve seat and the disk configured to perform the opening and closing function by forming a sealing surface on the outer edge portion of the groove forming the edge portion in close contact with the valve seat.

상기와 같이 구성된 본 발명의 밸브 시트와 디스크의 실링 구조는, 탄성력을 지닌 합성수지재의 패킹이 밸브 시트에 엄밀하게 밀착되어 개폐기능을 수행함과 더불어 금속재인 디스크에 형성된 실링면이 밸브 시트에 밀착하여 개폐기능을 수행하는 이중 실링 구조로서, 합성수지재의 패킹에 의하여 유출 없이 안정적으로 유로를 닫을 수 있으며, 고온에서 패킹이 녹아내려 기능을 상실하더라도 금속재 디스크 테두리부에 형성된 실링면이 개폐기능을 수행할 수 있어서 소방관련 배관에도 안심하고 설치할 수 있는 현저한 효과가 있는 밸브 시트와 디스크의 실링 구조이다.In the sealing structure of the valve seat and the disk of the present invention configured as described above, the packing of the synthetic resin material having elastic force closely adheres to the valve seat to perform the opening and closing function, and the sealing surface formed on the disk made of metal is in close contact with the valve seat. As a double sealing structure that performs the function, the flow path can be closed stably without leakage by the packing of synthetic resin material, and the sealing surface formed on the edge of the metal disk can perform the opening and closing function even if the packing melts at high temperature and loses the function. It is a sealing structure of valve seat and disc which has remarkable effect that can be installed safely in fire-related piping.

본 발명의 밸브 시트와 디스크의 실링 구조는 버터플라이 밸브와 같이 디스크의 회전운동으로 개폐되는 밸브보다 글로브 형 밸브와 앵글형 밸브와 같이 디스크가 직선왕복운동으로 밸브 시트에 밀착되거니 떨어지게 구성된 밸브에 용이하게 적용할 수 있는 구조인 데, 이는 유로를 닫을 때 디스크의 직선운동으로 실링면과 밸브 시트와 밀착될 때 작용하는 힘이 실링면 전체에 균일하게 분포되어 안정적으로 유출 없이 밸브를 닫을 수 있기 때문이다.The sealing structure of the valve seat and the disk of the present invention is easier for a valve configured to be in close contact with the valve seat in a linear reciprocating motion such as a globe valve and an angle valve, rather than a valve that is opened and closed by a rotational motion of a disk like a butterfly valve. It is a structure that can be applied in a simple way, because the force acting when the flow path is in close contact with the sealing surface and the valve seat when the flow path is closed is uniformly distributed throughout the sealing surface so that the valve can be closed stably without leakage. to be.
