본 발명이 관련된 볼밸브의 시트 구조는 도1을 통하여 알 수 있듯이 금속재의 볼(3)과 접촉하는 탄성을 지닌 비금속재(주로 고무, 불소고무, 테프론, 나일론등)의 시트링(Seat Ring)(13), 시트링(13)을 보지(保持)하는 시트리테이너(Seat-Retainer)(17), 시트리테이너(17)를 보조하는 스프링(16)과 가이드(15) 및 몸통(1)과 시트리테이너(17) 사이로의 유체 누설을 방지하기 위한 고무 오링(O-ring)(14)을 포함하여 구성되며, 이는 밸브 입구측(상류측)의 압력과 스프링(16)의 탄성력이 시트리테이너(17)에 전달되어 상기 시트리테이너(17)에 삽입설치된 시트링(13)이볼(3)에 탄력적으로 접촉함으로써 기밀을 유지하도록 되어 있다. 여기에서, 부호 2는 볼밸브 덮개, 4는 밸브대(Stem), 5는 하부 밸브대, 6은 패킹, 7,12는 부싱, 8은 가스켓, 9는 덮개 볼트, 10은 너트, 11은 와셔를 각각 나타낸다.The seat structure of the ball valve according to the present invention, as can be seen through Figure 1 seat ring of a non-metal material (mainly rubber, fluorine rubber, Teflon, nylon, etc.) having elasticity in contact with the metal ball (3) (13), a seat retainer (17) holding the seat ring (13), a spring (16), a guide (15) and a body (1) and a seat to assist the seat retainer (17). It comprises a rubber O-ring (14) for preventing fluid leakage between the retainers (17), the pressure of the valve inlet side (upstream side) and the elastic force of the spring (16) the seat retainer (17) Seat ring 13 inserted into the seat retainer 17 is elastically in contact with the ball 3 to maintain airtightness. Where 2 is a ball valve cover, 4 is a stem, 5 is a lower valve seat, 6 is a packing, 7 is 12 bushing, 8 is gasket, 9 is cover bolt, 10 is nut, 11 is washer Respectively.
그러나 이러한 구조의 경우 정상유동시나 저압의 경우에는 문제점이 도출되지 않으나, 동 밸브와 연결설치되는 배관계통의 내부 압력이 40kgf/㎠ 이상의 고압일 경우에는 밸브가 도2, 도3과 같이 닫힌 상태에서 밸브를 열려고 할 때, 밸브가 막 열리려고 하는 순간에 도4∼도6에서 상세히 도시한 바와 같이 입구측 배관내부로부터의 압력이 시트리테이너(17)의 시트링 홈부(18)에 유입되어 탄성을 지닌 비금속재의 시트링(13)을 시트리테이너(17)로부터 이탈되게 함으로써 밸브의 기능상실을 유발하는 일이 빈번한 문제가 있다.However, such a structure does not lead to problems during normal flow or low pressure. However, when the internal pressure of the piping connected to the valve is higher than 40 kgf / cm 2, the valve is closed as shown in FIGS. 2 and 3. When the valve is to be opened, at the moment when the valve is about to open, the pressure from the inside of the inlet pipe is introduced into the seating groove 18 of the seat retainer 17, as shown in detail in FIGS. It is frequently a problem to cause the malfunction of the valve by causing the non-metal seating ring 13 to be disengaged from the seat retainer 17.
따라서, 본 발명은 이러한 종래의 볼밸브에서 배관내부에 높은 압력이 유지되는 상태에서 볼밸브를 열 때 발생되는 시트링의 시트리테이너로부터의 이탈로 인한 밸브의 기능상실을 예방하고 볼밸브 본연의 기밀 및 작동기능을 유지할 수 있도록 함으로써 관련배관설비의 안전성과 우수한 기밀성을 유지하도록 할 수 있는 더욱 개선된 볼밸브 시트 구조를 제공하는데 그 목적이 있다.Therefore, the present invention prevents the malfunction of the valve due to the deviation from the seat retainer of the seat ring generated when opening the ball valve in the state of maintaining a high pressure in the pipe in such a conventional ball valve and the ball valve inherent hermetic And to provide a more improved ball valve seat structure that can maintain the safety and excellent airtightness of the associated piping equipment by maintaining the operation function.

이하에서, 상기의 목적을 달성하기 위한 본 발명을 첨부도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention for achieving the above object will be described in more detail.
즉, 본 발명은 밸브 몸통(1)내부의 유로를 개폐하는 수단으로서 밸브대(4)를 통해 일측 또는 타측으로의 회전조작이 가능하게 설치지지된 금속재의 볼(3)을 가지고, 또 상기 볼(3)에 대한 시트 구조로서 탄성을 지닌 비금속재의 시트링(13), 상기 시트링(13)을 보지하기 위한 시트리테이너(17), 상기 시트리테이너(17)를 볼(3)쪽으로 탄발시키도록 몸통(1)내부에 설치된 스프링(16) 및 스프링 가이드(15), 상기 시트리테이너(17)와 몸통(1)간의 유체누설을 방지하도록 시트리테이너(17) 및 몸통(1)사이의 적소에 설치된 고무재의 오링(14)을 포함하는 시트 구조를 가지는 볼밸브에 있어서, 상기 시트리테이너(17)의 시트링(13)이 삽입설치되는 홈부(18)의 가장자리에 상기 홈부(18)의 내측 공간과 시트리테이너(17)의 외측 공간사이를 연통시키는 복수의 압력분출구(19)들을 일정 간격을 두고 뚫어 설치하여서 된 볼밸브의 시트 구조를 제공한다.That is, the present invention has a metal ball (3) which is supported to be rotated to one side or the other side through the valve stem 4 as a means for opening and closing the flow path inside the valve body (1), the ball As the seat structure for (3), the elasticity of the non-metallic seat ring 13, the seat retainer 17 for holding the seat ring 13, and the seat retainer 17 are shot to the ball (3) Spring 16 and spring guide 15 installed inside the body 1, and installed in place between the seat retainer 17 and the body 1 to prevent fluid leakage between the seat retainer 17 and the body (1) In a ball valve having a seat structure including an O-ring 14 made of rubber, an inner space of the groove portion 18 is formed at an edge of the groove portion 18 into which the seat ring 13 of the seat retainer 17 is inserted. Working pressure outlets 19 for communicating between the outer space of the seat retainer 17 At a distance to provide a sheet structure of the ball valve installed hayeoseo drilled.
상기와 같이 구성된 볼밸브를 배관에 연결설치한 상태에서, 볼(3)의 입구측 배관내에 예컨대 40kgf/㎠ 이상의 높은 압력이 유지되어 있고 상기 볼(3)이 닫힌 위치에 있을 경우, 상기 볼(3)을 열림위치로 회전조작하면 볼(3)이 막 열리는 순간에 입구측의 압력은 도5에 예시된 바와 같이 시트리테이너(17)와 시트링(13)사이의 홈부(18)내측으로 집중적으로 몰려 들게 되고, 이와 같이 홈부(18)내측으로 작용하게 되는 압력은 상기 시트링(13)을 도6에 예시된 바와 같이 홈부(18) 외측으로 밀어내려는 힘으로 작용하게 되어서 동 시트링(13)을 시트리테이너(17)로부터 이탈시키게 된다.In the state where the ball valve configured as described above is connected to the pipe, when the high pressure of 40 kgf / cm 2 or more is maintained in the inlet pipe of the ball 3 and the ball 3 is in the closed position, the ball ( When 3) is rotated to the open position, at the moment when the ball 3 is just opened, the pressure at the inlet side is concentrated inside the groove 18 between the seat retainer 17 and the seat ring 13 as illustrated in FIG. In this way, the pressure acting inwardly into the groove 18 acts as a force to push the seat ring 13 out of the groove 18 as illustrated in FIG. ) Is separated from the seat retainer 17.

Since the pressure acting on the inside of the groove 18 of the seat retarder 17 is caused by the pressure, the seat is opened through the pressure ejection openings 19 which are opened when the seat ring 13 causes the elastic deformation of the degree illustrated in FIG. It is ejected to the outside of the retainer 17 and exits into the inner space of the valve body, whereby the pressure of the inlet pressure of the pipe and the pressure of the inner space of the valve body are balanced so that the seat ring 13 is grooved in the seat retainer 17. (18) It is possible to effectively prevent the departure from the outside, thereby avoiding the risk of valve malfunction due to the departure from the seat retainer 17 of the seat ring 13 as in the prior art of the related piping equipment It will be able to place a static high level of safety and confidentiality.
또한, 본 발명에 따른 볼밸브는 상기 시트리테이너(17)와 밸브 몸통(1)사이의 적소에 흑연재의 링(14-1)을 고무재의 오링(14)과 함께 설치구비하며, 이와 같이 함으로써 화재발생시 고무재의 오링(14)이 소실되더라도 흑연재의 링(14-1)은 소실됨이 없이 그대로 남아 밸브의 기밀을 유지시키도록 할 수 있어 밸브의 안전성을 더욱 높일 수 있는 효과가 얻어진다.In addition, the ball valve according to the present invention is provided with a ring 14-1 of graphite material together with the O-ring 14 of rubber material in place between the seat retainer 17 and the valve body (1). Even if the O-ring 14 of the rubber material is lost in the event of a fire, the ring 14-1 of the graphite material can remain without being lost to maintain the airtightness of the valve, thereby obtaining an effect of further increasing the safety of the valve.
나아가서, 도9는 본 발명에 따라 상기 시트리테이너(17)가 서로 결합, 분리가 가능한 두 시트리테이너 부분(17-1)(17-2)들로 구성되고, 상기 두 시트리테이너 부분(17-1)(17-2)들의 결합으로 이루어지는 시트링 홈부(18)내에 시트링(13)이 삽착지지 되게 한 경우의 실시예를 보여 준다. 이 실시예에 있어서, 상기의 두 분할 결합된 시트리테이너 부분(17-1)(17-2)들은 나사산들이 있는 결합부(17-3)를 통해 서로 나사식으로 결합되거나 분리될 수 있는데, 시트리테이너(17)를 이와 같이 구성할 경우 시트링 홈부(18)내에 시트링(13)을 더욱 용이하게 삽입설치할 수 있는 이점이 있다.Further, Fig. 9 is composed of two seat retainer parts 17-1 and 17-2, in which the seat retainers 17 are coupled to and separated from each other, according to the present invention, and the two seat retainer parts 17-1. ) Shows an embodiment in which the seat ring 13 is inserted into and supported in the seat ring groove 18 formed by the combination of the two parts 17-2.
