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 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.

1. A tap (4) including: a tap body ( 16) a valve assembly (14) located within the body; an operating handle ( 12) mounted on the body and coupled to the valve assembly; the body having a first part spherical bearing surface ( 76) and the handle being provided with a complementary bearing surface (104) whereby the handle is capable of biaxial rotation about first and second axes (40,44) relative to the tap body (16) wherein the valve assembly (14) includes: first valve means ( 50,52) for controlling flow of a first liquid from a first inlet (140) to a first outlet (146), the first valve means including a first valve element (168) which opens when the handle (12) is rotated from a closed position about said first axis (40) in a first sense to first open position to permit flow of the first liquid through the valve assembly (14); second valve means ( 134,176) for controlling flow of a second liquid from a second inlet (142) to a second outlet (144), the second valve means including a second valve element (190) which opens when the handle has been rotated from said closed position about said first axis (40) in a second sense opposite to said first sense to an active position and then rotated about said second axis (44); and a security element ( 42) having a locked position in which it prevents rotation of the handle (12) about said second axis (44), the security element being such that it can be moved to an unlocked position when the handle (12) is in said active position so that the handle (12) can rotate about the second axis (44) to a second open position to thereby permit flow of the second liquid through the valve assembly (14). 2. A tap as claimed in claim 1 wherein the valve assembly (14) includes a base plate (50) and wherein the first and second inlets (140,142) and the first and second outlets (146,144) arc bores through said plate (50). 3. A tap as claimed in claim 2 wherein the valve assembly (14) includes a valve disc (52) which sealingly engages a valve face (153) of the base plate (50) and wherein the valve disc (52) is mounted for rotation with the handle (12) about said first axis (40). 4. A tap as claimed in claim 3 wherein the first valve element includes said valve disc and a ceramic insert (158) and wherein the valve face includes a recess (156) within which is located said ceramic insert (158), the insert including first and second bores (160,162) which communicate with said first inlet and first outlet and wherein the valve disc includes a recess (168) which provides fluid communication between said first and second bores when the handle is in its first open position. 5. A tap as claimed in claim 2 wherein the base plate includes a spigot (134) having a spigot bore therethrough which forms said second inlet and wherein the second valve element is resilient and is biased into sealing engagement with the spigot to close said spigot bore unless the handle is moved to said second open position. 6. A tap as claimed in claim 5 wherein the second liquid flows into the valve chamber when the handle is in said second open position and wherein the first valve means includes a further bore which is aligned with the port in the base plate which forms said second outlet when the handle is in said active position. 7. A tap as claimed in claim 5 wherein the valve assembly includes, movable body portions (172,174) which together with said valve base plate define a valve chamber (60) within which a valve disc and the spigot are located. 8. A tap as claimed in claim 7 wherein the second valve means includes a diaphragm (176) which extends across said valve chamber and carries said second valve element (190). 9. A tap as claimed in claim 8 wherein the valve assembly includes a plunger (58) the lower end (234) of which is coupled to the diaphragm and wherein the upper end of the plunger is pivotally connected to said handle, the arrangement being such that on rotation of the handle about said second axis, the plunger is raised thereby unseating the second valve element from the spigot bore thereby enabling the second liquid to pass through the spigot bore; through the valve chamber, through the disc bore and through the second outlet. 10. A tap as claimed in claim 8 wherein the diaphragm is clamped between said movable body portions. 11. A tap as claimed in claim 7 wherein the movable body portions are mounted for rotation with the handle about said first axis. 12. A tap as claimed in claim 11 wherein an upper one (172) of said movable body portions is formed with pivot shafts (216) which are coupled to the handle (12) by means of a locking member (220) to thereby form a pivotal connection which permits rotation of said handle about said second axis and rotation of the movable body portions (172,174) with the handle about said first axis. 13. A tap as claimed in claim 2 wherein the security element is a button mounted for reciprocating movement in a button opening (106) in the handle. 14. A tap as claimed in claim 13 wherein a compression spring (114) biases the button to its locked position which prevents rotation of the handle about said second axis. 15. A tap as claimed in claim 14 wherein the tap body is formed with a cam member (80) which co-operates with an interlocking projection (120) on said button. 16. A tap as claimed in claim 15 wherein said cam member (80) is formed adjacent to said first part spherical bearing surface (76) and tapers in width, the arrangement being such that when the handle (12) is in said closed position, the cam (80) engages said interlocking projection (120) and prevents rotation of the handle (12) about said second axis (44) but, when the handle is rotated to said active position and the security burton (42) is pressed inwardly to its unlocked position the interlocking projection (120) disengages said cam (80) whereby the handle (12) can be rotated about said second axis (44). 17. A dispensing system (2) for dispensing chilled water and boiling or nearly boiling water, including a tap (4) as claimed in claim 1 wherein the first liquid is chilled water supplied from a chilled water line (24) connected to said first inlet (140), the tap having a chilled water outlet line (28) extending from the first outlet (146) to a tap outlet (8,10); and wherein the second liquid is mains water supplied from a mains water line ( 26) connected to said second inlet (142); and boiler unit ( 16) having an inlet (18) coupled to receive mains water from the second outlet (144) and an outlet line (32) extending to the tap outlet (8,10). 18. A system as claimed in claim 17 wherein the boiler unit (16) includes a vent outlet (22) which is coupled to said tap outlet (8,10) by a vent line (34).
