Abstract

An arrangement having at least one valve, in particular a vacuum valve, with a closure member of the valve for closing a through-opening of the valve and a drive for adjusting the closure member between a closed position, in which the closure member closes the through-opening, and at least one open position, in which the closure member opens the through-opening at least in regions. For the thermal loading of the closure member, the valve has a chamber for a heat transfer fluid, connected in a thermally conducting manner to the closure member and closed off, preferably permanently, in relation to the through-opening. A supply line of the arrangement opens into the chamber, supplying heat transfer fluid for the thermal loading of the closure member to the chamber. At least one heat exchanger for the thermal loading of the heat transfer fluid is arranged in the supply line.

First claim

The invention claimed is:

1. An arrangement comprising:
at least one valve having at least one closure member for closing at least one through-opening of the valve, and at least one drive for adjusting the closure member between a closed position, in which the closure member closes the through-opening, and at least one open position, in which the closure member opens the through-opening at least in regions,
wherein, for thermal loading of the closure member, the at least one valve has at least one chamber for a heat transfer fluid, said chamber being connected in a thermally conducting manner to the closure member and being closed off in relation to the through-opening,
at least one supply line opens out into the chamber, said supply line supplying the heat transfer fluid into the chamber for thermal loading of the closure member, at least one heat exchanger for the thermal loading of the heat transfer fluid arranged in the supply line,
the heat exchanger is operatively arranged between a discharge line and the supply line, and
the supply line and the discharge line pass into the heat exchanger which removes heat or cold from the heat transfer fluid in the discharge line and transfers it to the heat transfer fluid in the supply line.

2. The arrangement as claimed in claim 1 , wherein in addition to the heat exchanger, at least one of a heating or cooling device is arranged in the supply line for the thermal loading of the heat transfer fluid.

3. The arrangement as claimed in claim 2 , wherein the at least one of the heating or cooling device is controllable.

4. The arrangement as claimed in claim 1 , wherein in addition to the heat exchanger at least one pump or at least one blower is arranged in the supply line for conveying the heat transfer fluid.

5. The arrangement as claimed in claim 4 , wherein the at least one pump or the at least one blower is controllable.

6. The arrangement as claimed in claim 1 , wherein the chamber, the supply line, and the discharge line of the arrangement for the heat transfer fluid flowing out of the chamber form a heat transfer fluid circuit which is closed per se or form part of said heat transfer fluid circuit.

7. The arrangement as claimed in claim 6 , wherein the chamber is defined at least in regions by the closure member and by a bellows or a sliding sleeve.

8. The arrangement as claimed in claim 7 , wherein the valve has at least one valve seat, against which the closure member abuts in the closed position, and the chamber is arranged on a side of the closure member remote from the valve seat.

9. The arrangement as claimed in claim 6 , wherein the valve is a corner valve or a sliding valve.

10. The arrangement as claimed in claim 6 , wherein the valve is a vacuum valve.

11. The arrangement as claimed in claim 1 , wherein the at least one chamber is permanently closed off from the through-opening.

12. The arrangement as claimed in claim 1 , wherein the valve is a corner valve or a sliding valve.

13. The arrangement as claimed in claim 1 , wherein the valve is a vacuum valve.

14. The arrangement as claimed in claim 1 , wherein the valve has at least one valve seat, against which the closure member abuts in the closed position, and the chamber is arranged on a side of the closure member remote from the valve seat.
