본 발명은 배관라인에 설치되는 배관용 슬립조인트에 관한 것으로, 그 구조를 개선하여 조립성을 향상시키고 축 방향의 변위를 흡수함은 물론이고 지진 등에 의한 좌우/상하 및 굽힘 등 진동 및 변위를 동시에 흡수할 수 있도록 한 것이다. 이를 위해, 본 발명은 유체가 통과하는 엔드 파이프(50)와, 상기 엔드 파이프(50)의 외주면에 수평 이동 가능하게 설치되는 가이드 파이프(60)와, 상기 가이드 파이프(60)의 일단에 용접 고정되어 회전력이 작용될 때 틸팅모멘트를 흡수하는 가변 홈(71)을 갖는 링 부재(70)와, 상기 링 부재(70)의 타단에 용접 고정되어 가이드 파이프(60)의 내부에 이송유체 가압공간(A)이 형성되도록 하며, 적어도 1개 이상의 주름부(81)가 형성된 하우징(80)과, 상기 하우징(80)에 형성된 주름부(81)에 끼워져 엔드 파이프(50)의 외주면에 기밀이 유지되게 설치되는 패킹부재(90)로 구성하고, 상기 링 부재(70)가 판상의 링으로 형성되고, 외주면에는 환상의 가변 홈(71)이 형성한 것을 특징으로 한다.

신축이음

본 고안은 신축이음에 관한 것으로서, 특히, 용접 이음새를 최소화하여 조립이 용이하고 소음 발생을 줄일 수 있도록 이루어진 새로운 구조의 신축이음을 제공하는데 그 주된 목적이 있다. 이와 같은 목적을 달성하기 위한 본 고안에 따른 신축이음은 원통 형상으로 대향 형성되면서 내측으로 내통이 설치된 벨로우즈를 구비한 한쌍의 외통이 커플링을 통해 연결되고 상기 외통의 끝단으로는 원통 형상으로 한쌍의 미끄럼 부재가 삽입되어 볼트 결합되고, 상기 외통 내부로 부터 상기 미끄럼 부재를 통해 원통 형상으로 한쌍의 단관이 미끄럼되게 삽입 설치되고, 상기 단관의 끝단으로 플랜지가 나사 결합되고, 상기 플랜지 외부로 부터 밀착되게 끼워져 원형의 박편으로 된 한쌍의 엔드 플레이트가 상기 벨로우즈로 부터 연장된 끝단과 용접된다. 이러한 구성으로 이루어진 신축이음은 용접 이음새 또는 접합부를 최소화할 수 있는 신축이음을 제공하여 조립 및 분해가 매우 용이하며 용접작업에 따른 공정 시간을 현저히 단축할 수 있는 장점이 있으며 수축 및 이완 등에 의한 금속마찰음을 제거할 수 있어 발생되는 소음을 크게 줄일 수 있는 탁월한 효과가 있다.

管接头

本发明的管接头通过环形的密封件把管接头的承接口与插口间密封。密封件的栓塞部具有与踵部连续的第一栓塞、位于比第一栓塞更靠承接口内侧的第二栓塞、和存在于第一栓塞与第二栓塞的边界的缩颈部。第一栓塞压接在承接口的内周面，第二栓塞压接在插口的外周面。第二栓塞在被设于承接口跟插口间之前的自然状态下从第一栓塞朝管中心倾斜，其内径在所述自然状态下小于插口的外径，而且，能通过缩颈部的弹性变形沿管径方向自由地扩大缩小。
