Description

가압식 패킹부재를 이용한 배관 커플러Piping Coupler Using Pressurized Packing Member
본 발명은 가압식 패킹부재를 이용한 배관 커플러에 관한 것으로, 보다 상세하게는 서로 다른 크기의 홈과 돌기를 갖는 밀폐링과 가압링의 조합으로 이루어진 패킹부재가 가압수단에 의해 상호 압착되는 경우 밀폐링의 날개부가 가압링에 의해 양측 폭방향으로 벌어지도록 구성되어 관체의 이음매 또는 틈새의 확실한 수밀 또는 기밀을 보장할 수 있는 가압식 패킹부재를 이용한 배관 커플러에 관한 것이다.The present invention relates to a pipe coupler using a pressurized packing member, and more particularly, when a packing member made of a combination of a sealing ring and a pressurizing ring having grooves and protrusions of different sizes is pressed together by a pressurizing means. It relates to a pipe coupler using a pressurized packing member which is configured such that the wing portion is opened in both width directions by the pressure ring to ensure a reliable watertightness or airtightness of the seam or gap of the pipe.
패킹부재는 수밀 또는 기밀이 요구되는 관체의 이음매 또는 틈새에 체결되는 부재를 일컫는 것으로, 종래에는 고무 등과 같이 탄성을 갖는 소재로 이루어져 원형 또는 사각 단면을 갖고 환형으로 형성된 오링을 주로 패킹부재로 이용하여 왔다.The packing member refers to a member that is fastened to a joint or a gap of a tubular body requiring watertightness or airtightness. Conventionally, the packing member is made of an elastic material such as rubber and has an circular or square cross-section and has an annular ring mainly used as a packing member. come.
하지만, 패킹부재로 이용되는 종래의 오링만으로는 탄성에 의한 부피변화의 한계로 인해 특히, 고압의 유체가 흐르는 경우 관체의 이음매 또는 틈새를 확실하게 밀폐하는 데에는 한계가 있었다. However, only the conventional O-ring used as the packing member has a limitation in tightly sealing the seams or gaps of the tube due to the limitation of the volume change due to elasticity, especially when a high pressure fluid flows.
또한, 배관작업은 일정한 길이로 제조된 파이프를 설치환경에 맞추어 다수개를 절단 및 연결하여 관로를 형성하는 작업을 통칭하며, 상기와 같은 배관작업에 있어서는 제한적인 파이프의 길이와 관로의 위치 변경의 필요성으로 인하여 배관 커플러가 사용되고 있다.In addition, plumbing work is a collectively referred to the work to form a pipe by cutting and connecting a plurality of pipes made of a certain length in accordance with the installation environment, in the above piping work is limited of the length of the pipe and the position of the pipe change Due to necessity, pipe couplers are used.

그러나 이러한 종래의 통상적인 배관 커플러는 파이프를 회전시키면서 삽입하여야 하므로 그 기밀성과 작업성이 용이하지 못한 문제점이 있었다.However, such a conventional pipe coupler has to be inserted while rotating the pipe has a problem that its airtightness and workability is not easy.
상기와 같은 종래의 통상적인 배관 커플러의 단점을 해결해보고자, 대한민국 등록실용신안 제0381922호(등록일자: 2005.04.07)에는 패킹부재를 구비한 파이프 연결장치가 제안된 바 있다.In order to solve the shortcomings of the conventional pipe coupler as described above, the Republic of Korea Utility Model No. 0381922 (Registration Date: 2005.04.07) has been proposed a pipe connecting device having a packing member.
