Abstract

Valve includes a passage in which a valve seat and a movable sealing element are provided for blocking the passage. The valve is embodied in a double-walled manner, such as a housing, so as to be provided with an intermediate space. The valve includes a function monitoring device. A safety tank includes a double-walled container and at least one discharge port to which a valve is connected.

Claims

1. Valve, comprising:

a) a passage;

b) a valve seat and a moveable sealing element being provided in the passage for blocking the passage;

c) a double-walled housing defining an intermediate space; and

d) a function monitoring device being provided, the function monitoring device being configured for monitoring the function of the valve.

2. Valve according to claim 1, wherein:

a) the valve is configured so that it is connectable to a discharge port of a double-walled container.

3. Valve according to claim 2, wherein:

a) the function monitoring device includes a measuring chamber provided on the sealing element on the valve seat.

4. Valve according to claim 3, wherein:

a) the measuring chamber is a channel.

5. Valve according to claim 4, wherein:

a) a passage is provided which connects the measuring chamber with an outside of the housing.

6. Valve according to claim 4, wherein:

a) a transducer is provided in the measuring chamber.

7. Valve according to claim 1, wherein:

a) the sealing element is double-walled.

8. Valve according to claim 7, wherein:

a) the double-walled sealing element includes a monitoring space that has a connection to the measuring chamber in at least one position.

9. Valve according to claim 1, wherein:

a) a monitoring device configured to record a measured pressure is provided.

10. Valve according to claim 9, wherein:

a) the monitoring device includes an interface to exchange one of data and commands with a computer network.

11. Valve according to claim 1, wherein:

a) a three-position control valve is provided.

12. Valve according to claim 11, wherein:

a) a lift of the sealing element is 0 to 100% in the partially open position.

13. Valve according to claim 12, wherein:

a) the lift of the sealing element can be adjusted in the partially opened position.

14. Valve according to claim 12, wherein:

a) the lift of the sealing element is 0 to 15% in the partially open position.

15. Valve according to claim 1, wherein:

a) the valve is configured so that it is connectable to a discharge port of a double-walled line.

16. Valve according to claim 1, wherein:

a) the function monitoring device includes at least one measuring chamber provided on the valve seat.

17. Safety tank with a double-walled container and at least one discharge port, wherein:

a) the valve according to claim 1 is attached to the discharge port.
