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.

초록

The portable tank defines a chamber within which is disposed a liner having a sealing interface with a tank discharge assembly. The features of the sealing interface of the liner with the discharge assembly and this discharge assembly itself virtually eliminate any risk that contents of the tank will seep or flow into the space outside of the liner and between the liner and the inner walls of the tank. The method of installing and using the liner system are also disclosed.

The assembly of claim 7 wherein the gasket flange includes first and second oppositely-disposed ribs, and with the gasket flange sandwiched between the assembly and gasket flanges, the first rib fitting into a groove in the assembly flange and the second rib fitting into a groove in the gasket flange. 9. The assembly of claim 1 further comprising a clamp which holds the assembly and end flanges together. 10. The assembly of claim 1 wherein the tunic includes a nipple at the tank opening and to which the discharge tube is secured. 11. The assembly of claim 10 wherein the discharge tube is threaded onto the nipple. 12. The assembly of claim 1 wherein the tube member extends out beyond the end flange. 13. A storage tank assembly, comprising: a tank having a nipple at an outlet opening; a flexible liner disposed in the tank and adapted to store product; an elbow adapted to be secured to the nipple; a flexible tube disposed in the elbow and secured to the flexible liner; and a gasket which threads onto a distal end of the flexible tube. 14. The assembly of claim 13 wherein the flexible tube is welded into the flexible liner. 15. The assembly of claim 13 wherein the flexible liner comprises a bag constructed of polyethylene film. 16. The assembly of claim 13 wherein the flexible tube includes an end flange which is secured to the flexible liner. 17. The assembly of claim 16 wherein the end flange has a flat circular disc shape with a central through-passageway. 18. The assembly of claim 13 wherein the liner includes a fitting, the fitting being adapted to be received in the outlet opening, and the tube being securable at a proximal end thereof to the fitting. 19. The assembly of claim 13 wherein the elbow includes an elbow flange, and further comprising a valve assembly have a valve flange and a gasket having a gasket flange, the gasket flange being clamped between the elbow flange and the valve flange. 20. The assembly of claim 19 wherein the flexible tube is secured to the gasket. 21. A storage tank assembly, comprising: a tank; a flexible liner disposed in the tank and adapted to store product therein; a discharge assembly out through which product in the liner can be discharged; the discharge assembly including a discharge tube secured to the tank at a tank discharge opening; the discharge tube having an end flange; the discharge assembly including a tube member disposed in the discharge tube; a gasket assembly having a gasket flange; a valve assembly having an assembly flange, the assembly flange being securable relative to the end flange with the gasket flange sandwiched therebetween; and a clamp which holds the assembly and end flanges together. 22.
