Valve controller for pressure stabilization
Method and apparatus for controlling pressure in a pressure vessel. A plurality of valves between a pressure source and a pressure vessel can be selectively opened or turned off, singularly or in combinations, to control pressure in the pressure vessel. A maximum pressure threshold and a minimum pressure threshold can be established based on operating considerations of the pressure vessel. One or more of the valves can be turned on when the pressure in the pressure vessel reaches the minimum pressure threshold. One or more of the valves can be turned off when the pressure in the pressure vessel reaches the maximum pressure threshold.
1. A method for regulating pressure in a pressure vessel connected to a pressure source by a plurality of valves, the method comprising:
receiving a maximum pressure threshold value;
receiving a minimum pressure threshold value;
receiving, from a pressure sensor, a pressure signal indicating a pressure in the pressure vessel;
upon a value of the pressure signal dropping below the minimum pressure threshold value, opening at least one valve of the plurality of valves; and
upon a value of the pressure signal rising above the maximum pressure threshold value, closing at least one valve of the plurality of valves.
2. The method of claim 1 , further comprising:
receiving an engagement signal; and
opening at least one valve of the plurality of valves upon receiving the engagement signal.
3. The method of claim 1 , wherein, after opening at least one valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a second valve of the plurality of valves.
4. The method of claim 3 , wherein, after opening at least a second valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a third valve of the plurality of valves.
5. The method of claim 4 , wherein, after opening at least a third valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a fourth valve of the plurality of valves.
6. The method of claim 1 , wherein, after closing at least one valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a second valve of the plurality of valves.
7. The method of claim 6 , wherein, after closing at least a second valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a third valve of the plurality of valves.
8. The method of claim 7 , wherein, after closing at least a third valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a fourth valve of the plurality of valves.
9. A non-transitory computer-readable storage medium containing computer-readable program code that, when executed by operation of one or more computer processors, performs an operation comprising:
receiving a maximum pressure threshold value;
receiving a minimum pressure threshold value;
receiving a pressure signal indicating a pressure in the pressure vessel;
upon a value of the pressure signal dropping below the minimum pressure threshold value, opening at least one valve of the plurality of valves; and
upon a value of the pressure signal rising above the maximum pressure threshold value, closing at least one valve of the plurality of valves.
10. The non-transitory computer-readable storage medium of claim 9 , wherein the computer-readable program code performs further operations comprising:
receiving an engagement signal; and
opening at least one valve of the plurality of valves upon receiving the engagement signal.
11. The non-transitory computer-readable storage medium of claim 9 , wherein, after opening at least one valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a second valve of the plurality of valves.
12. The non-transitory computer-readable storage medium of claim 11 , wherein, after opening at least a second valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a third valve of the plurality of valves.
13. The non-transitory computer-readable storage medium of claim 12 , wherein, after opening at least a third valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains below the minimum pressure threshold value, opening at least a fourth valve of the plurality of valves.
14. The non-transitory computer-readable storage medium of claim 9 , wherein, after closing at least one valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a second valve of the plurality of valves.
15. The non-transitory computer-readable storage medium of claim 14 , wherein, after closing at least a second valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a third valve of the plurality of valves.
16. The non-transitory computer-readable storage medium of claim 15 , wherein, after closing at least a third valve of the plurality of valves, upon the pressure signal indicating that the pressure in the pressure vessel remains above the maximum pressure threshold value, closing at least a fourth valve of the plurality of valves.
