Abstract

A draining valve for draining the boiler may include a first port connected to a pressurized tank, a second port connected to an output tube, a third port connected to the boiler, and a control valve to selectively connect the pressurized tank to the boiler and to connect the boiler to the output tube. The first port may be adapted to be closed while the third port is open, and the first port may be adapted to be opened while the third port is closed. The second port may be opened while the first port is closed, and the second port may be open while the first port is open. The central valve may include a central passageway, and the central valve may include a traverse passageway. The first port may selectively connect to the traverse passageway, and the third port may selectively connect to the traverse passageway. The second port may connect to the central passageway.

Claims

1. ) A draining valve for draining the boiler, comprising:

a first port connected to a pressurized tank;

a second port connected to an output tube;

a third port connected to the boiler;

a control valve to selectively connect the pressurized tank to the boiler and to connect the boiler to the output tube.

2. ) A draining valve for draining the boiler as in claim 1, wherein the first port is adapted to be closed while the third port is open.

3. ) A draining valve for draining the boiler as in claim 1, wherein the first port is adapted to be opened while the third port is closed.

4. ) A draining valve for draining the boiler as in claim 1, wherein the second port is opened while the first port is closed.

5. ) A draining valve for draining the boiler as in claim 1, wherein the second port is open while the first port is open.

6. ) A draining valve for draining the boiler as in claim 1, wherein the central valve includes a central passageway.

7. ) A draining valve for draining the boiler as in claim 1, wherein the central valve includes a traverse passageway.

8. ) A draining valve for draining the boiler as in claim 7, wherein the first port selectively connects to the traverse passageway.

9. ) A draining valve for draining the boiler as in claim 7, wherein the third port selectively connects to the traverse passageway.

10. ) A draining valve for draining the boiler as in claim 6, wherein the second port connects to the central passageway.

11. ) A method for draining the boiler, comprising the steps of;

opening a first port connected to a pressurized tank;

closing a second port connected to an output tube;

opening a third port connected to a boiler;

pressurizing the boiler;

closing the first port connected to the pressurized tank

opening the second port connected to the output tube in order to drain the boiler.

12. ) A method for draining the boiler as in claim 11, wherein the above steps are repeated.
