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 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

A stuffing box for use in oil and gas wells having improved sealing. A plurality of ring-like packing glands each has an outer surface defining an inverted frusto-conical shape and a bore therethrough also defining an internal inverted frusto-conical surface whereby the glands nest upon one another in cup-like fashion. A ring-like seal seat also has a bore forming an inverted frustco-conical inner surface which, in assembly, carries the nested glands. The inner wall of a stuffing box body defines a cavity which contains the assembly, the seat thereof being carried by a lower shoulder portion defined by the body. A cylindrical gland cap has a lower gland follower edge portion which exerts downward pressure on the end of the uppermost gland. The vertical bore through the body, seat, glands, and gland cap is adapted to receive a vertical reciprocating polished rod in coaxial alignment therewith whereby the downward pressure of the gland follower effects sealing of the inner and outer surfaces of the glands to the rod and to the inner wall of the body, respectively. Sealing is pressure-enhanced by borehole pressure, and any misalignment of the rod is compensated for by providing for horizontal movement of the seat, glands, and gland cap relative to the box.
