Abstract

Disclosed is a valve arrangement for underground control of a fluid flow and an associated method, the arrangement including a valve having a valve housing containing fluid control means for controlling a flow of fluid through pipe means arranged below the surface of the ground, where the fluid control means is actuated by means of mechanical manipulation of an operating device of the valve and the operating device is coupled to the fluid control means, the valve having valve identification means including data regarding the specific valve type, where the valve arrangement further includes an extension device including an extension device housing surrounding an extension rod, where the extension rod is rotatably supported by the extension device housing, where the extension rod is mechanically coupled to the operating device to enable the mechanical manipulation being performed at the ground surface, and the extension device further includes dedicated connection means extending between a valve end and a ground surface end of the extension device, and the valve end is arranged at the valve housing and the ground surface end is arranged at the opposite end of the extension device, where the dedicated connection means enable that the data regarding the specific valve type may be communicated to the ground surface.

Claims

1. A valve arrangement for underground control of a fluid flow, said valve arrangement comprising:

a valve including a valve housing containing a gate for controlling a flow of fluid through a channel arranged below the surface of the ground, wherein said gate is actuated by means of mechanical manipulation of an operating device of said valve, said operating device being coupled to said gate, and wherein said valve further comprises a valve identification tag including data regarding the specific valve type,

an extension device comprising an extension device housing substantially surrounding an extension rod, wherein said extension rod is rotatably supported by said extension device housing, said extension rod being mechanically coupled to said operating device to enable said mechanical manipulation being performed at said ground surface, wherein said extension device further comprises a conductor extending between a valve end and a ground surface end of said extension device,

said valve end being arranged at said valve housing and said ground surface end being arranged at the opposite end of said extension device, wherein said conductor is configured to exchange signals between an identity reading device at said ground surface and said valve identification tag to enable that said data regarding said specific valve type may be communicated to said ground surface, and

wherein said conductor is directly arranged on or in said extension device housing.

2. A valve arrangement according to claim 1, wherein said valve arrangement further comprises a connection coupling arranged to connect said valve identification tag and said conductor between said valve and said extension device.

3. A valve arrangement according to claim 2, wherein said connection coupling is arranged at a transition area between said valve and said extension device.

4. A valve arrangement according to claim 2, wherein said connection coupling is rigidly connected to said valve and said extension device.

5. A valve arrangement according to claim 2, wherein said connection coupling is formed separate from said valve and said extension device.

6. A valve arrangement according to claim 2, wherein said connection coupling comprises a matching plug and a socket.

7. A valve arrangement according to claim 1, wherein said conductor comprises conducting means for conducting electrical signals and/or power.

8. A valve arrangement according to claim 1, wherein said valve identification tag is a RFID tag.

9. A valve arrangement according to claim 1, wherein said valve identification tag is powered by a power source arranged at said valve.

10. A valve arrangement according to claim 1, wherein said valve identification tag is powered trough said conductor from an external power source.

11. A valve arrangement according to claim 1, wherein said valve arrangement further comprises power conducting means for conducting power from an external power source to said valve identification tag.

12. A valve arrangement according to claim 1, wherein said extension device comprises impulse means arranged to generate an electrical impulse power from an external power source.

13. A valve arrangement according to claim 1, wherein said valve arrangement comprises fastening devices for connecting said valve and said extension device together.

14. A valve arrangement according to claim 1, wherein said valve further comprises valve status means for detecting an operating status of said valve.

15. A valve arrangement according to claim 14, wherein said valve arrangement further comprises valve status communication means for communicating said operating status of said valve to said conductor.

16. A valve arrangement according to claim 1, wherein said valve further comprises data logging means for logging data regarding the operation of said valve.

17. A valve arrangement according to claim 16, wherein said valve arrangement further comprises data logging communication means for communicating said logged data of said valve to said conductor.

18. A valve arrangement according to claim 1, wherein the length of said extension device is between about 100 mm and about 10,000 mm.

19. A valve arrangement according to claim 1, wherein said conductor is arranged on or in said extension rod.

20. A valve arrangement according to claim 1, wherein said extension device comprising bearing means arranged between said extension device housing and said extension rod to enable said rotatable support.

21. A valve arrangement according to claim 1, wherein said extension device comprising ground surface end bearing means and valve end bearing means arranged at opposite ends of said extension device between said extension device housing and said extension rod to enable said rotatable support.

22. A valve arrangement according to claim 1, wherein said valve identification tag is integrated in said valve housing.

23. A valve arrangement according to claim 1, wherein said valve identification tag is mounted on a surface of said valve housing.

24. A valve arrangement according to claim 1, configured for ground surface control of a fluid flow in an underground channel.

25. A method for identifying an underground valve of a valve arrangement comprising an extension device being connected to said valve, said method comprising the steps of:

coupling an identity reading device to a ground surface end of said extension device, wherein said ground surface end of said extension device is arranged opposite an valve end of said extension device, wherein said valve end is connected to said valve,

exchanging signals and/or electrical power between said identity reading device and a valve identification tag of said valve through a conductor extending between said valve end and said ground surface end of said extension device so that data of said valve identification tag may be read by means of said identity reading device, and

disconnecting said identity reading device from said extension device.

26. A method according to claim 25, wherein said method further comprises the step of supplying power to said valve identification tag at least during said reading of said data.

27. A method according to claim 25, wherein said method further comprises the step of activating a power source arranged at said valve at least during said reading of said data.

28. A method according to claim 25, wherein said method is a method for identifying an underground valve of a valve arrangement.
