Abstract

A valve and sensor arrangement includes a valve which has a valve member. A sensor such as a sensor for detecting a flow of water through the valve is provided within the valve member and is preferably perpendicular to a turning axis of the valve member. The sensor is preferably a flow sensor which is rotated by flow through the valve and the sensor arrangement may be provided in a valve of general utility.

Claims

1. A valve and sensor arrangement, comprising:

a valve including a housing and a valve member, said housing comprising an interior chamber and an inlet and an outlet, said valve member being provided within said interior chamber and comprising a passageway, said valve member being movable about a turning axis between a first position which provides communication between the inlet and the outlet of the housing and a second position which restricts communication between the inlet and the outlet of the housing; and

sensor means for sensing a condition of the passageway of the valve member, said sensor means including a sensor element which is provided within said passageway of said valve member, said sensor means being mounted on said housing of the valve with said sensor element being provided within said passageway of said valve member, said sensor element extending within the valve member through an opening in the valve member at an angle with respect to the turning axis of said valve member.

2. The arrangement of claim 1 wherein said sensor element extends generally perpendicularly to said turning axis of said valve member.

3. The arrangement of claim 1 wherein said valve member prevents communication between the inlet and the outlet of the housing when the valve member is in said second position and wherein said sensor element is releasably mounted on said housing of the valve, said sensor element being removable from said passageway while said valve member is in said second position preventing communication between said inlet and said outlet.

4. The arrangement of claim 1 wherein said sensor element senses temperature.

5. The arrangement of claim 1 wherein said sensor element senses pressure.

6. The arrangement of claim 1 wherein said sensor element senses a flow through the passageway.

7. The arrangement of claim 1 wherein said sensor element senses a flow through said interior chamber of said housing, said sensor element extending within the valve member generally perpendicularly with respect to the turning axis of the valve member.

8. The arrangement of claim 7 wherein the sensing element is arranged to be deflected by a flow through the valve member.

9. The arrangement of claim 1 wherein said sensor element is arranged to be rotated about a longitudinal axis of said sensor element by a flow through the passageway.

10. The arrangement of claim 9 wherein said sensor element is arranged to be rotated about a longitudinal axis of said sensor element by a flow through the passageway, said longitudinal axis of said sensor element being substantially perpendicular to said axis of rotation of said valve member.

11. The arrangement of claim 10 wherein said sensor element includes a shaft having a vane, said longitudinal axis of said sensor element being along said shaft.

12. The arrangement of claim 10 wherein said sensor element includes a shaft having first and second vanes, one of said first and second vanes being fixed to said shaft and the other of said vanes being hinged to said shaft.

13. A valve and sensing arrangement, comprising:

a housing defining an interior chamber having an inlet and at least one outlet,

a valve member provided within said interior chamber, the valve member having at least one passageway through the valve member, said valve member having an axis of rotation;

means for selectively moving said valve member within said interior chamber whereby communication between said inlet and said outlet may be restricted;

means for enabling a condition in said interior chamber of said housing to be sensed;

access means for communicating said means for enabling a condition in said interior chamber to be sensed with said passageway of said valve member, said access means including an access way through said housing and through said valve member, said access way being selectively closed by a member which is releasably received by said housing, said access way being substantially perpendicular to said axis of rotation of said valve member.

14. The arrangement of claim 13 wherein said means for enabling a condition in said interior chamber of said housing to be sensed includes a sensor element which senses temperature.

15. The arrangement of claim 13 wherein said means for enabling a condition in said interior chamber of said housing to be sensed includes a sensor element which senses pressure.

16. The arrangement of claim 13 wherein said means for enabling a condition in said interior chamber of said housing to be sensed includes a sensor element which senses a flow through the passageway.

17. A valve, comprising:

a housing defining an interior chamber having an inlet and at least one outlet,

a valve member provided within said interior chamber, the valve member having at least one passageway through the valve member,

means for selectively moving said valve member within said interior chamber whereby communication between said inlet and said outlet may be restricted,

means for sensing a flow through said interior chamber of said housing, said means for sensing a flow including a sensing member which extends from said housing to within said valve member, at an angle with respect to a turning axis of said valve member, said valve member having an opening which receives the means for sensing when said valve member is selectively moved within said interior chamber.

18. The valve of claim 17 wherein said sensing member which extends within said valve member is arranged to be deflected by a flow through the valve member.

19. A ball valve and sensor arrangement, comprising:

a ball valve including a housing and a ball valve member, said housing comprising an interior chamber and an inlet and an outlet, said ball valve member being provided within said interior chamber and comprising a passageway, said ball valve member being movable between a first position which provides communication between the inlet and the outlet of the housing and a second position which prevents communication between the inlet and the outlet of the housing; and

sensor means for sensing a condition of the passageway of the ball valve member, said sensor means including a sensor element which is provided within said passageway of said valve member, said sensor means being mounted on said housing of the ball valve with said sensor element being provided within said passageway of said ball valve member at an angle with respect to a turning axis of said ball valve member.

20. The arrangement of claim 19 further comprising means for removing said sensor element from said passageway while said ball valve member is in said second position preventing communication between said inlet and said outlet.

21. The arrangement of claim 20 wherein said sensor element senses temperature.

22. The arrangement of claim 20 wherein said sensor element senses pressure.

23. The arrangement of claim 20 wherein said sensor element senses a flow through the passageway.

24. The arrangement of claim 20 wherein said sensor element senses a flow through said interior chamber of said housing, said sensor element extending within the ball valve member generally perpendicular to a turning axis of the ball valve member.

25. The arrangement of claim 24 wherein the sensing element is arranged to be deflected by a flow through the ball valve member.

26. The arrangement of claim 19 wherein said ball valve member has an axis of rotation and wherein said means for removing said sensing member includes an access way through said housing and through said valve member, said access way being substantially perpendicular to said axis of rotation of said valve member.
