본 고안은 압력유체 급송관의 회전가능한 관 연결구조에 관한 것으로, 특히 초고압(약 1000기압이상)의 압력 유체를 급송하는 강관에 있어서 내부압력유체가 외부로 누설되지 아니하고 연결구조의 일측이 회전가능하게 이루어진 관연결구조에 관한 것이다.The present invention relates to a rotatable pipe connection structure of a pressure fluid supply pipe, and particularly in a steel pipe for supplying a pressure fluid of very high pressure (about 1000 atm or more), one side of the connection structure can be rotated without the internal pressure fluid leaking to the outside. It is related to the pipe structure consisting of.

종래에 있어서 초고압의 압력유체를 급송하는 강관의 연결구조는 움직일수 없는 고정구조를 채택하거나 아니면 연결부위자체는 움직일수 없으나 관자체를 어느정도 가요성이 있도록 제작된 압력유체용 호스를 연결하여 사용하는 정도가 고작이었다.In the related art, the connection structure of the steel pipe for feeding the ultra high pressure pressure fluid adopts a fixed structure that cannot move, or the connection part itself cannot move, but it is used by connecting a hose for pressure fluid that is made to be flexible to the pipe itself. It was only about.

따라서 회전이 불가능한 고정구조의 채택으로 인하여는 사용 및 적용분야가 크게 제한을 받게되고 압력유체를 사용하는 기존의 공작기계나 자동화기계에 적용하기가 대단히 어려운 문제점이 있으며 상기와 같은 압력호스의 사용시엔 그 사용수명이 짧아 비경제적인 단점이 있다.Therefore, due to the adoption of the non-rotating fixed structure, the use and application fields are greatly limited, and it is very difficult to apply to existing machine tools or automated machines that use pressure fluids. Its short service life has an uneconomical disadvantage.

본 고안은 이와같은 종래의 문제점을 해소하고자 안출된 것으로서, 몸체와 회전체의 결합구성에 있어서 급송되는 압력유체가 원활하게 급송되면서 내부압력유체의 누설을 방지할 수 있는 연결구조를 채택하여 완벽한 기밀유지기능과 함께 회전체가 회전이 가능하며 수류절단기계, 세척기계, 공작기계나 로보트등에 이용하는 경우 자동화가 용이하고 그 사용수명을 크게 연장시킬 수 있는 관연결구조를 제공하는데 그 목적이 있다.The present invention was devised to solve such a conventional problem, and the airtight pressure fluid in the coupling structure of the body and the rotating body is smoothly fed while adopting a connection structure that prevents leakage of the internal pressure fluid.
