본 고안은 비교적 고압의 유체 흐름을 개폐하는데 주로 사용하는 볼 벨브의 시트링에 관한 것이다.The present invention relates to the seating of a ball valve mainly used to open and close a relatively high pressure fluid flow.

종래의 볼 벨브의 시트링은 강성의 금속제로 되어 있으나 강한 유체압을 받으면 누압되는 폐단이 있고, 또한 장기 사용하게 되면 재질 자체의 마모로 여유 틈이 생겨 완벽한 기밀 상태로 유지할 수 없는 문제점이 있었던 것이다.The seating of the conventional ball valve is made of rigid metal, but there is a closed end that is pressurized when subjected to a strong fluid pressure, and if it is used for a long time, there is a problem that it can not be maintained in a perfect airtight state due to the wear of the material itself. .

본 고안은 이상의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 금속제로 된 시트링을 구성함에 있어 몸체의 내주면에 링 형상의 요입 홈조를 형성하면서 공실이 형성되게하고, 이 공실 내에 강한 유체압에 접하면 몸체가 외향으로 벌어지면서 볼형상으로 된 변체에 밀접되어 수밀되어지게 한 것이다.The present invention has been made to solve the above problems, and the subject matter of the present invention is to form a ring-shaped recess groove in the inner circumferential surface of the body to form a seat ring made of metal, so that the vacancy is formed, and the strong fluid pressure in the vacancy When contacted, the body opens outward and closes to the ball-shaped deformed body.

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.

벨브 몸체(4)에 끼움되게한 금속제로 된 시트링 몸체(1)의 내주면에 요입홈조(3)가 형성되면서 트임부(1') 및 공실(3')이 생기게 하고, 몸체(1)의 주면 일측면에는 만곡면(2)이 형성 되어진 구조이다.The recessed groove 3 is formed on the inner circumferential surface of the sheeting body 1 made of metal fitted to the valve body 4 so that a slit 1 'and an empty space 3' are formed, and the body 1 One side of the main surface is a structure in which the curved surface (2) is formed.

이상과 같이 구성된 본 고안은 비교적 고압유체의 흐름을 차폐하는 볼 벨브의 시트링으로 사용하는 것인 바, 이를 사용함에 있어 시트링 몸체(1)의 만곡면(2)이 벨브 몸체(4)의 내부 전후측에 끼움 설치되어 통수공(5')이 있는 볼 형상의 변체(5)의 좌우측에 위치되게 끼움 설치하여 사용하는 것인 바, 유체의 흐름을 차폐 하였을 때는 공실(3')이 비교적 높은 외압을 받게 되는데, 이때의 높은 외압은 시트링 몸체(1)의 요입홈(3)에 형성된 공실(3')이 미치게 되고, 이와 같이 미치게 되면 공실(3') 자체는 고압에 의해 밖으로 벌어지는 경향이 생기게 되고, 이와 같이 벌어지면 상대적으로 시트링 몸체(1)가 벌어지면서 이의 만곡면(2)이 볼 형상으로 된 변체(5)와 밀접되어 기밀 상태로 더욱 확실히 해주게 된다.The present invention configured as described above is to be used as the seating of the ball valve to shield the flow of relatively high-pressure fluid, in using the curved surface (2) of the seating body (1) of the valve body (4) It is fitted to the front and back side inside, and is used to be installed on the left and right sides of the ball-shaped deformed body 5 with the water hole 5 '. The high external pressure at this time is the vacancy (3 ') formed in the recessed groove (3) of the seating body (1) is crazy, and if it is mad like this, the vacancy (3') itself is opened out by high pressure When the opening occurs in this way, the seating body 1 is relatively opened, and the curved surface 2 thereof is in close contact with the deformed body 5 in the shape of a ball, thereby making it more secure.

이상과 같이 본 고안은 금속제로 된 시트링 몸체(1)의 내주면에 형성된 개구부(1')에 원주 방향으로 요입홈조(3)를 형성하면서 생긴 공실(3')이 심한 유체압을 받으면 상대적으로 부피가 커지면서 이의 외주면에 형성된 만곡면(2)이 볼 형상으로 된 변체(5)에 밀접되어 기밀 상태로 확실히 할 수 있게 하였기 때문에 매우 실용적이다.As described above, the present invention is relatively effective when the vacancy 3 'generated by forming the recessed groove 3 in the circumferential direction is formed in the opening 1' formed on the inner circumferential surface of the sheeting body 1 made of metal. As the volume increases, the curved surface 2 formed on the outer circumferential surface thereof is very practical because it makes it possible to ensure the airtight state in close contact with the deformed body 5 in the shape of a ball.
