연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A conduit coupling includes first and second conduits, an annular adapter and a clamp. The first conduit has an annular flange on an outer surface adjacent to a first end. The adapter is coupled to the outer surface of the first conduit and has an annular first engagement surface positioned adjacent to the flange and an annular second engagement surface that is spherical and convex. The second conduit has a flared end with an inner surface and an outer surface. The inner surface includes an adapter engagement surface that is spherical and concave and engageable with the second engagement surface. The outer surface includes a clamp engagement surface and the clamp includes a flared end engagement surface that is engageable with the clamp engagement surface. The clamp is configured to urge the flared end, adapter and annular flange together.

1. A conduit coupling, comprising: a first conduit;an annular flange on an outer surface of the first conduit adjacent to an end of the first conduit;an annular adapter coupled to the outer surface of the first conduit, the adapter comprising a body including an annular first engagement surface positioned adjacent to the flange and an annular second engagement surface that is spherical and convex, the second engagement surface being spaced from and opposed to the first engagement surface;a second conduit comprising a flared end, the flared end having an inner surface comprising an adapter engagement surface that is spherical and concave, the adapter engagement surface being engageable with the second engagement surface, the flared end also comprising a clamp engagement surface; anda clamp comprising a flared end engagement surface that is engageable with the clamp engagement surface, the clamp being configured to urge the annular flange, the adapter, and the flared end together upon tightening the clamp, wherein the flared end engagement surface of the clamp is spherical and concave and wherein the clamp engagement surface of the flared end is spherical and convex. 2. The coupling of claim 1, wherein the adapter comprises a rigid middle portion between first and second gasket portions. 3. The coupling of claim 2, wherein the first and second gasket portions of the adapter comprise a high temperature resistant material. 4. The coupling of claim 3, wherein the middle portion of the adapter comprises steel. 5. The coupling of claim 1, wherein a cross-sectional shape of the adapter, taken in an axial direction of the first conduit, is substantially trapezoidal. 6. The coupling of claim 1, wherein the second engagement surface, the adapter engagement surface, the clamp engagement surface, and the flared end engagement surface have substantially the same center of curvature. 7. The coupling of claim 6, wherein the center of curvature of the second engagement surface, the adapter engagement surface, the clamp engagement surface, and the flared end engagement surface is located on a longitudinal center axis of the first conduit. 8. The coupling of claim 1, wherein the second engagement surface of the adapter and the adapter engagement surface of the flared end have substantially the same radii of curvature. 9. The coupling of claim 1, wherein the first and second engagement surfaces converge moving away from a longitudinal center axis of the first conduit. 10. The coupling of claim 1, wherein at least one of the first and second conduits is coupled to an engine or an exhaust after treatment device. 11. A conduit coupling, comprising: a first conduit having a first longitudinal center axis, a first end portion, and an annular flange on an outer surface of the first end portion;a second conduit having a second longitudinal center axis and a flared end portion, the flared end portion having an inner surface comprising an adapter engagement surface that is spherical and concave; andan annular adapter held in compression and forming a sealed joint between the first and second conduits, the adapter comprising a rigid middle portion between first and second gasket portions that are less rigid than the middle portion, the first gasket portion comprising an annular first engagement surface positioned adjacent to the flange and the second gasket portion comprising an annular second engagement surface that is spherical and convex, the second engagement surface being spaced from and opposed to the first engagement surface, the adapter engagement surface being engaged with the second engagement surface;wherein the sealed joint is maintainable while the second conduit is misaligned relative to the first conduit in each of, and in combinations of, the following manners: (1) translated in a direction of the longitudinal center axis of the first conduit,(2) rotated about the longitudinal center axis of the second conduit, and(3) pivoted about a point on the longitudinal center axis of the first conduit. 12. The coupling of claim 1, wherein the second engagement surface of the adapter and the adapter engagement surface of the flared end have a common center of curvature located on a longitudinal center axis of the first conduit. 13. The coupling of claim 1, wherein the clamp engagement surface of the second conduit and the flared end engagement surface of the clamp have a common center of curvature located on a longitudinal center axis of the first conduit. 14. The conduit coupling of claim 11, wherein the second engagement surface of the adapter and the adapter engagement surface of the flared end portion have the same center of curvature, the center of curvature being the point on the longitudinal center axis of the first conduit. 15. A conduit coupling, comprising: a first conduit;an annular flange on an outer surface of the first conduit adjacent to and spaced from an end of the first conduit, the flange comprising a first side surface nearer to the end of the first conduit than a second side surface, wherein the first and second side surfaces converge moving away from a longitudinal center axis of the first conduit;an annular adapter coupled to the outer surface of the first conduit, the adapter comprising a body including an annular first engagement surface positioned adjacent to the flange and an annular second engagement surface that is spherical and convex, the second engagement surface being spaced from and opposed to the first engagement surface, wherein a cross-sectional shape of the adapter, taken in an axial direction of the first conduit, is substantially trapezoidal and the first and second engagement surfaces converge moving away from a longitudinal center axis of the first conduit;a second conduit comprising a flared end having an inner surface and an outer surface, the inner surface comprising an adapter engagement surface that is spherical and concave and engageable with the second engagement surface of the adapter, the outer surface comprising a clamp engagement surface that is spherical and convex; anda clamp comprising a flared end engagement surface that is spherical and concave and engageable with the clamp engagement surface of the flared end, wherein the clamp also contacts the second side surface of the flange, and wherein the clamp is configured to urge the annular flange, the adapter, and the flared end together to form a sealed joint between the first and second conduits;wherein the adapter engagement surface and the second engagement surface of the adapter have substantially the same radii of curvature and the flared end engagement surface and the clamp engagement surface have substantially similar radii of curvature;wherein the second engagement surface, the adapter engagement surface, the clamp engagement surface, and the flared end engagement surface have substantially the same center of curvature, the center of curvature being a point on the longitudinal center axis of the first conduit; andwherein the second conduit comprises a second longitudinal center axis and the sealed joint is maintainable when the first and second longitudinal center axes are substantially misaligned. 16.
