볼 밸브{A ball valve}A ball valve

본 고안은 볼 밸브에 관한 것으로, 보다 상세하게는 유로의 개폐가 원활하게 이루어지면서도 조립이 매우 용이할 뿐만 아니라 개폐시에도 누수가 효과적으로 방지되는 볼 밸브에 관한 것이다. The present invention relates to a ball valve, and more particularly to a ball valve that is easy to assemble and open and close the flow path as well as to effectively prevent leakage during opening and closing.

볼 밸브는 유체나 기체의 흐름을 단속하는 제어밸브의 일종으로, 가격이 비교적 저렴하여 수도관이나 도시가스관 또는 냉매관 기타 유체나 기체를 동력원으로 사용하는 장치에 연결되는 관로상에 많이 설치된다. Ball valve is a kind of control valve that regulates the flow of fluid or gas. The ball valve is relatively inexpensive, so it is installed on a pipeline connected to a water pipe, a city gas pipe, a refrigerant pipe, or a device using a fluid or gas as a power source.

도 1은 종래에 사용되던 볼 밸브의 일례를 도시한 것으로, 도시된 바와 같이, 종래 볼 밸브는 직교되는 두 면에 관이 결합되는 관이음부(11, 12)가 형성되고 그 중 하나의 관이음부(11)와 수평으로 연통되는 삽입공(13)이 형성된 밸브몸체(10)와, 일측이 상기 밸브몸체(10)의 내부에 구비되고 타측이 상기 삽입공(13)을 통해 밸브몸체(10) 외부로 돌출된 개폐부재(20)와, 이 개폐부재(20)의 타측에 결합된 밸브(30)로 이루어진다. Figure 1 shows an example of a ball valve used in the prior art, as shown, the conventional ball valve is formed with pipe fittings (11, 12) are coupled to the pipe orthogonal to two sides of one of the pipe A valve body 10 having an insertion hole 13 communicating horizontally with the joint portion 11 and one side is provided inside the valve body 10, and the other side of the valve body 10 is inserted through the insertion hole 13. 10) the opening and closing member 20 protruding to the outside, and the valve 30 is coupled to the other side of the opening and closing member 20.

상기 개폐부재(20)는 바 형상으로 일단부에는 볼 형상의 유로형성부(21)가 구비되고 타단부에는 나사산(22)이 형성되며, 상기 유로형성부(21)에는 각 관이음부(11, 12)와 연통되도록 연통공(23)이 형성된다. 그리고, 개폐부재(20)의 타단부에 형성된 나사산(22)에는 사용자가 조작할 수 있는 밸브(30)가 너트(31)에 의해 연결되어, 밸브(30)의 작동에 따라 개폐부재(20)가 회전되면서 밸브몸체(10) 내부에 유로가 형성된다. The opening and closing member 20 has a bar shape and has a ball-shaped flow path forming portion 21 at one end thereof, and a thread 22 formed at the other end thereof, and each pipe fitting portion 11 is formed at the flow path forming portion 21. Communication hole 23 is formed to communicate with, 12). In addition, a valve 30 operable by a user is connected to the thread 22 formed at the other end of the opening and closing member 20 by a nut 31, and the opening and closing member 20 is operated in accordance with the operation of the valve 30. Is rotated while the flow path is formed inside the valve body (10).

이때, 상기 개폐부재(20)를 밸브몸체(10)에 결합하는 과정을 살펴보면, 개폐부재(20)의 타단부가 관이음부(11)와 삽입공(13)을 순차적으로 통과하도록 개폐부재(20)를 밸브몸체(10)에 강제로 압입하게 된다. 이때, 개폐부재(20)의 유로형성부(21)가 위치되는 밸브몸체(10)의 내부에는 누수방지를 위한 실링부재(14)가 구비되는데, 개폐부재(20)를 압입하는 과정에서 유로형성부(21)가 실링부재(14)에 걸려서 압입하기가 쉽지 않은 문제가 있다. 한편, 상기 압입을 용이하게 하려고 유로형성부(21)에 면취부(22)를 형성하게 되는데, 이로 인해 실링부재(14)가 유로형성부(21)를 덜 가압하게 될 뿐만 아니라 유로형성부(21)와 실링부재(14)가 면접촉되는 면적이 작아져서 누수의 위험이 증대되는 문제가 있다. At this time, looking at the process of coupling the opening and closing member 20 to the valve body 10, the other end of the opening and closing member 20 to sequentially open the opening and closing member (11) and the insertion hole 13 ( 20) is forcibly pressed into the valve body (10). At this time, the sealing member 14 for preventing leakage is provided in the valve body 10 in which the flow path forming part 21 of the opening and closing member 20 is located, and the flow path is formed in the process of pressing the opening and closing member 20. Part 21 is caught in the sealing member 14 there is a problem that it is not easy to press. Meanwhile, in order to facilitate the press-fitting, the chamfering part 22 is formed in the flow path forming part 21. As a result, the sealing member 14 not only presses the flow path forming part 21 less but also the flow path forming part ( 21) and the sealing member 14 has a problem that the area of the surface contact is small, the risk of leakage increases.
