Body inclined portions (113, 114) are formed on the inner diameter of the right and left connection portions (111, 112) of the body (110), and a first sealing front inclined portion (141) of the first sealing (140) is coupled to the body inclined portions (113, 114), respectively. In addition, a first sealing back inclined portion (142) is formed on the back surface of the first sealing (140), and a second sealing front inclined portion (151) of the second sealing (150) is coupled to the first sealing back inclined portion (142). The present invention can conveniently and reliably seal between the right and left connection portions (111, 112), the right and left nuts (120, 130) and the right and left tubes (200) (300) by the first sealing and the second sealing with an O-ring interposed therebetween.

Description

튜브체결구Tube fastener
본발명은 튜브체결구에 관한 것으로, 보다 상세하게는 여러 개의 튜브를 연결결합하는 튜브체결구에 실링을 설치하여 기밀성을 향상시킨 튜브체결구에 관한 것이다.The present invention relates to a tube fastener, and more particularly, to a tube fastener that improves airtightness by installing a seal in a tube fastener connecting multiple tubes.
일반적으로 공개특허공보 10-2011-0014407에 배경기술로 기재된 바와 같이, 액체나 기체를 이송시키기 위한 배관용으로 사용되는 관은 규격에 따라 일정한 길이로 제작되므로 원하는 길이 및 형태의 관로를 형성하기 위해서는 다수의 관을 서로 연결하여 사용하게 된다. 이에 따라, 다양한 재질 및 형태로 이루어진 관 연결구가 관의 연결을 위해 사용되고 있으며, 이러한 관 연결구는 이송되는 유체가 관 연결부를 통해 누설되지 않도록 밀폐시킬 수 있는 구조로 이루어진다.In general, as described in the background of the Patent Publication No. 10-2011-0014407, the pipe used for the pipe for transferring the liquid or gas is made of a constant length according to the specification to form a pipe of the desired length and shape Multiple pipes are connected to each other. Accordingly, pipe connectors made of various materials and shapes are used for the connection of the pipes, and these pipe connectors have a structure that can be sealed so that the fluid to be transported does not leak through the pipe connections.
이러한, 배관은 재질에 따라 여러 종류가 시판 및 사용되고 있으나, 일반적으로 가장 많이 사용되는 것은 동합금, 알루미늄 등의 경금속을 이용하여 제작되는 비철금속관과, PVC와 같은 합성수지를 이용하는 합성수지관이     These pipes are commercially available and used in various types depending on the material, but the most commonly used pipes are non-ferrous metal pipes made of light metals such as copper alloy and aluminum, and synthetic resin pipes using synthetic resin such as PVC.
많이 사용되고 있는 실정이며, 배관을 연결하는 배관 부속품은 그 용도에 따라 배관의 방향을 전환시키는 엘보와, 기존 배관에서 새로운 배관을 분기시키는 티와 배관과 다른 배관을 직선으로 연결시키는 유니온 이음 등이 있으며 이러한 배관 부속품과 배관을 연결하는 방법 또한 다양하게 개발되어 사용되고 있다.Piping accessories that connect pipes include elbows that divert pipes according to their purpose, tees that branch new pipes from existing pipes, and union joints that connect pipes and other pipes in a straight line. Various methods for connecting such piping accessories and pipes have also been developed and used.
통상적으로, 금속 소재로 이루어진 관의 연결에 사용되는 종래의 관 연결구는 중공의 몸체의 배관 형태에 따라 적어도 둘 이상의 관 단부가 삽입될 수 있도록 복수의 관 삽입구를 형성하고, 이 관 삽입구의 외주면에 나사를 형성하여 구성된 것으로써 연결되는 각 관의 단부에도 나사를 형성하여 관 연결구의 삽입구에 관을 돌려 끼워 결합할 수 있도록 구성된다.     Conventionally, the conventional tube connector used for the connection of a tube made of a metal material forms a plurality of tube inserts so that at least two tube ends can be inserted according to the pipe form of the hollow body, and the outer peripheral surface of the tube insert It is configured to form a screw to form a screw in the end of each pipe to be connected is configured to be coupled to the tube by turning the tube into the insertion port of the pipe connector.
그러나, 이러한 종래의 관 연결구는 관 연결부를 완전히 밀폐시킬 수 없기 때문에, 관을 관 연결구에 결합시키기 전에 합성수지 등으로 이루어진 별도의 실링부재를 나사가 형성된 관 연결부에 감아주어야 하며, 관 연결부가 나사의 형성을 위해 절삭됨으로 인해 관 연결부의 강도가 현저히 저하되는 문제점이 있었다. 상기의 문제점을 개선한 것으로 관을 연결하기 위한 연결구에 밸브를 구비하여 유체가 수용된 상태의 관을 분리하더라도 내부의 유체가 외부로 누출되지 않도록 하고, 연결구를 체결하게 되면 밸브가 열리게 되어 관이 소통되는 착탈이 자유로운 관 연결구가 공개되어 있다.     However, since such a conventional pipe joint cannot completely seal the pipe joint, a separate sealing member made of synthetic resin or the like must be wound on the threaded pipe joint before the pipe is coupled to the pipe joint. There was a problem that the strength of the pipe connection is significantly lowered due to cutting to form. In order to improve the above problems, the valve is provided at the connector for connecting the pipe so that the fluid inside does not leak to the outside even when the pipe is separated from the fluid contained therein, and the valve opens when the connector is tightened. The detachable pipe connector is open to the public.
한편, 종래기술인 공개특허공보 10-2004-0084507호에는, 한쌍의 관을 연결하기 위한 연결구에 있어서, 중공이 형성된 관체로 마련되며, 일측 또는 양측에 수나사부가 형성되며, 수나사부에 대하여 단턱을 형성하여 관의 중공에 삽입되어 결합되는 삽입단이 형성되는 몸체부와, 삽입단에 결합된 관의 외주면에 위치하고, 외주면의 경사면에 의해 형성되는 외가압면이 마련되어 관의 외주면을 가압하여 삽입단에 관을 밀착시키는 가압부와, 가압부를 수용하는 형상으로 가압부의 외주면에 위치하여 몸체부에 형성된 수나사부에 결합되는 암나사부가 형성되고, 내측면에 가압부의 외가압면을 가압하는 내가압면이 형성되는 체결부가 마련되는 것을 특징으로 하는 관연결구가 공개되어 있다.     On the other hand, Korean Patent Laid-Open Publication No. 10-2004-0084507, in the connector for connecting a pair of pipes, is provided with a hollow body formed with a male thread, one side or both sides are formed with a male thread portion, forming a stepped portion with respect to the male thread portion And a body portion having an insertion end coupled to the hollow of the tube and formed on the outer circumferential surface of the tube coupled to the insertion end, and an external pressing surface formed by the inclined surface of the outer circumferential surface to pressurize the outer circumferential surface of the tube to the insertion end. A press portion for tightly fitting the tube, and a female screw portion formed on the outer circumferential surface of the press portion in a shape for accommodating the press portion and coupled to a male screw portion formed on the body portion, and an inner pressure surface for pressing the outer pressurization surface of the press portion on the inner side is formed. The tube connector is disclosed, characterized in that the fastening portion is provided.
그러나 상기와 같은 종래의 튜브체결구는 구조가 복잡하며, 또한 기밀작용이 충분히 이루어지지 않아 튜브 내 유체가 누설이 되는 단점이 있었다.     However, the conventional tube fasteners as described above have a disadvantage in that the structure is complicated, and the fluid in the tube leaks due to insufficient sealing.
본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 본발명은 오링을 개재한 제1실링과, 제2실링에 의하여 바디의 연결부, 너트 및 튜브 사이를 간편하고 확실하게 기밀작용을 할 수 있는 튜브체결구를 제공하고자 하는 것이다.The present invention has been made to solve the problems described above, the present invention is to provide a simple and reliable airtight between the connection of the body, the nut and the tube by the first sealing and the second sealing via the O-ring.
