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 drain valve has a housing defining a drain conduit for the passage of fluids to be drained, the drain conduit having a first rim defining an inlet to the drain conduit opposite a second rim defining an outlet from the drain conduit. One or more non-return valves are within the drain conduit between the first rim and the second rim and have a closed configuration and an open configuration adapted to allow fluids to flow through the outlet of the drain conduit. A vent conduit extends within the drain conduit and comprises internally a lower valve seat, an upper valve seat and a bypass valve positioned between the lower valve seat and the upper valve seat. The bypass valve is adapted to allow gas to bypass the one or more non-return valves and escape to atmosphere when the gas reaches a predetermined pressure.

1. A drain valve comprising: a housing defining a drain conduit for the passage of fluids to be drained, the drain conduit having a first rim defining an inlet to the drain conduit opposite a second rim defining an outlet from the drain conduit;one or more non-return valves within the drain conduit between the first rim and the second rim and having a closed configuration and an open configuration adapted to allow fluids to flow through the outlet of the drain conduit; anda vent conduit extending within the drain conduit and comprising internally: a lower valve seat;an upper valve seat; anda bypass valve positioned between the lower valve seat and the upper valve seat, the bypass valve adapted to allow gas to bypass the one or more non-return valves and escape to atmosphere when the gas reaches a predetermined pressure,wherein the vent conduit has a vent conduit outlet at a location higher than the first rim of the housing in an installed orientation. 2. The drain valve of claim 1, wherein the lower valve seat is positioned in the vent conduit proximate an uppermost of the one or more non-return valves, and the upper valve seat is positioned in the vent conduit proximate the vent conduit outlet. 3. The drain valve of claim 1, further comprising a float valve positioned between the bypass valve and the upper valve seat, the float valve being lighter in weight than the bypass valve and adapted to float in liquid. 4. The drain valve of claim 1, wherein the vent conduit is aligned with a central axis of the housing, the drain valve further comprising: one or more struts each connected to the vent conduit outlet at a first end and the housing at a second end, the one or more struts each having an opening though which gas from the vent conduit outlet flows. 5. The drain valve of claim 4, wherein the opening in the one or more struts is on an undersurface that faces the drain conduit. 6. The drain valve of claim 4, wherein the first end of each of the one or more struts connected to the vent conduit is higher on the central axis than the second end of each of the one or more struts connected to the housing in the installed orientation. 7. The drain valve of claim 1, further comprising a manually adjustable vent control member accessible external to the housing for selectively blocking flow through the vent conduit outlet to the atmosphere. 8. The drain valve of claim 4, further comprising a manually adjustable vent control member accessible external to the housing for selectively blocking flow through the vent conduit outlet to the atmosphere, the vent control member positioned at the first end of the one or more struts and within the vent conduit outlet, the manually adjustable vent control member being adjustable to allow flow through selected one or more struts. 9. The drain valve of claim 1, wherein the vent conduit is aligned with a central axis of the housing, the drain valve further comprising: one or more struts each connected to the vent conduit at a first end and the housing at a second end; anda vent post extending higher than the first end of the one or more struts in the installed orientation and having a distal vent end through which gas is vented to atmosphere. 10. The drain valve of claim 1, wherein the vent conduit has a first portion that extends along an internal surface of the drain conduit to the first rim of the housing and a second portion that extends obliquely from the first portion at the first rim and toward a central axis of the housing, the vent conduit outlet positioned at a distal part of the second portion. 11. A drain valve system comprising: a housing arranged to be located in a drain opening, the housing having a central axis and defining a drain conduit for the passage of fluids to be drained;one or more non-return valves supported within the housing on a post aligned with the central axis of the housing, wherein each of the one or more non-return valves has an open position and a closed position;a bypass flow passage arranged to provide a flow that bypasses the one or more non-return valves while in the closed position, the flow in the bypass flow passage adapted to flow in a direction opposite to flow allowed by the one or more non-return valves when in the open position, wherein the post is hollow and the bypass flow passage extends through an interior of the post; anda vent opening of the bypass flow passage is positioned closer to an upper rim of the housing than to the one or more non-return valves and configured to vent to atmosphere. 12. The drain valve system of claim 11, further comprising a first float valve member in the bypass flow passage, wherein a first float valve seat is defined in the bypass flow passage, and wherein when the first float valve member sits on the first float valve seat, flow through the bypass flow passage is blocked. 13. The drain valve system of claim 12, further comprising a second float valve member in the bypass flow passage, wherein a second float valve seat is defined in the bypass flow passage, and wherein when the second float valve member sits on the second float valve seat, flow through the bypass flow passage is blocked. 14. The drain valve system of claim 11, further comprising a strut extending between the upper rim of the housing and the post through which the bypass flow passage extends, wherein flow through the bypass flow passage will exit through an opening in the strut. 15. The drain valve system of claim 14, wherein at least a portion of the strut extends above the upper rim of the housing. 16. The drain valve system of claim 11, further comprising a manually adjustable vent control member for selectively setting a vent amount for the bypass flow passage. 17. The drain valve system of claim 14, further comprising a vent control member positioned at a junction between the post and the strut and accessible external to the housing for manual adjustment, the vent control member adjustable to allow or block flow through the bypass flow passage in the strut. 18. A drain valve comprising: a housing defining a drain conduit for the passage of fluids to be drained, the drain conduit having a first rim defining an inlet to the drain conduit opposite a second rim defining an outlet from the drain conduit;one or more non-return valves within the drain conduit between the first rim and the second rim and having a closed configuration and an open configuration adapted to allow fluids to flow through the outlet of the drain conduit; anda vent conduit extending within the drain conduit and comprising internally: a lower valve seat;an upper valve seat; anda bypass valve positioned between the lower valve seat and the upper valve seat, the bypass valve adapted to allow gas to bypass the one or more non-return valves and escape to atmosphere when the gas reaches a predetermined pressure,wherein the vent conduit is aligned with a central axis of the housing, the drain valve further comprising: one or more struts each connected to the vent conduit outlet at a first end and the housing at a second end, the one or more struts each having an opening though which gas from the vent conduit outlet flows.
