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.

Fluid flow control members for use with valves are described. An example poppet apparatus for use with an internal valve includes first and second opposing seating surfaces to control fluid flow through the internal valve. Additionally, the example poppet apparatus includes an aperture to receive a stem of the internal valve. Further, the example poppet apparatus includes a flow diverter to divert fluid flow through the poppet apparatus to substantially prevent the fluid flow from compressing a spring to be at least partially positioned in the poppet app...

1. A poppet apparatus for use with an internal valve, comprising: first and second opposing seating surfaces to control fluid flow through the internal valve;an aperture to receive a stem of the internal valve, the aperture positioned between the first and second seating surfaces; anda flow diverter at least partially defining a flow channel and the aperture, the flow diverter comprising a third surface and a fourth surface opposite the third surface, the third surface to be engaged by an end of a spring, the spring to be at least partially positioned in the poppet apparatus and to at least partially surround the flow diverter, the fourth surface to divert fluid flow through the flow channel and substantially around the end of the spring to substantially prevent the fluid flow from compressing the spring. 2. The poppet apparatus as defined in claim 1, wherein the flow diverter includes a shoulder proximate the flow channel, wherein the shoulder comprises the third and fourth surfaces. 3. The poppet apparatus as defined in claim 2, wherein the flow channel is to fluidly couple a chamber of the internal valve to another chamber. 4. The poppet apparatus as defined in claim 1, wherein the flow diverter is integrally coupled to the poppet apparatus. 5. The poppet apparatus as defined in claim 1, further comprising a plate coupled to the poppet apparatus, wherein the plate defines an opening sized to limit the fluid flow through the poppet apparatus when a spring seat coupled to the stem is proximate the opening. 6. The poppet apparatus as defined in claim 5, further comprising a curved surface that surrounds the opening to align the spring seat relative to the opening. 7. The poppet apparatus as defined in claim 6, wherein the curved surface is symmetrical relative to a lateral axis of the plate to enable the plate to be coupled to the poppet apparatus via either a first side of the plate or a second side of the plate. 8. The poppet apparatus as defined in claim 5, wherein the opening is sized to provide a distance of approximately 0.09 millimeters between a surface adjacent the opening and an exterior surface of the spring seat when the spring seat is positioned adjacent the opening. 9. A poppet apparatus for use with an internal valve, comprising: a first body having a first seating surface to sealingly engage a second body of the internal valve, wherein the first body defines: a second seating surface opposite the first seating surface to sealingly engage a plug of the internal valve;an aperture to receive a stem of the internal valve, the aperture positioned between the first and second seating surfaces;a bore at least partially concentric with the aperture; anda fluid flow channel positioned between the aperture and the second seating surface, the fluid flow channel and the aperture being concentric along a length of the fluid flow channel, wherein the fluid flow channel is different than the aperture; anda plate coupled to the poppet apparatus, wherein at least one of the plate or the bore define an opening sized to substantially limit fluid flow through the poppet apparatus when a spring seat coupled to the stem is positioned adjacent the opening. 10. The poppet apparatus as defined in claim 9, further comprising a flow diverter at least partially defining the fluid flow channel, the flow diverter comprising a third surface and a fourth surface opposite the third surface, the third surface to be engaged by an end of a spring, the spring to be at least partially positioned within the bore and to at least partially surround the flow diverter, the fourth surface to divert the fluid flow through the fluid flow channel and substantially around the end of the spring to substantially prevent the fluid flow from compressing the spring. 11. The poppet apparatus as defined in claim 10, wherein the flow diverter includes a shoulder proximate the fluid flow channel, wherein the shoulder comprises the third and fourth surfaces. 12. The poppet apparatus as defined in claim 9, further comprising a curved surface that surrounds the opening to align the spring seat relative to the opening. 13. The poppet apparatus as defined in claim 9, wherein the opening is sized to provide a distance of approximately 0.09 millimeters between a surface adjacent the opening and an exterior surface of the spring seat when the spring seat is positioned adjacent the opening. 14. An internal valve, comprising: a body that defines a chamber, wherein the body includes external threads to threadably engage another body;a stem assembly having a biasing element, wherein the stem assembly is to exert a force on a poppet to urge the poppet toward the body to control fluid flow through the internal valve; wherein the poppet comprises: a first seating surface opposite a second seating surface;an aperture to receive a stem of the internal valve, the aperture positioned between the first and second seating surfaces;a bore at least partially concentric with the aperture; anda fluid flow channel positioned between the aperture and the first seating surface of the poppet, the fluid flow channel and the aperture being concentric along a length of the fluid flow channel, wherein the fluid flow channel is different than the aperture; anda plate coupled to the poppet, wherein at least one of the plate or the bore define an opening sized to substantially limit the fluid flow through the poppet when a spring seat coupled to the stem is positioned adjacent the opening. 15. The internal valve as defined in claim 14, further comprising a flow diverter at least partially defining the fluid flow channel, the flow diverter comprising a third surface and a fourth surface opposite the third surface, the third surface to be engaged by an end of a second biasing element, the second biasing element to be at least partially positioned within the bore and to at least partially surround the flow diverter, the fourth surface to divert fluid flow through the fluid flow channel and substantially around the end of the second biasing element to substantially prevent the fluid flow from compressing the second biasing element. 16. The internal valve as defined in claim 14, further comprising a curved surface that surrounds the opening to align the spring seat relative to the opening. 17. The internal valve as defined in claim 14, wherein the opening is sized to provide a distance of approximately 0.09 millimeters between a surface adjacent the opening and an exterior surface of the spring seat when the spring seat is positioned adjacent the opening. 18. The poppet apparatus as defined in claim 10, wherein the flow diverter is to at least partially define the aperture.
