Abstract
A dump valve positioned between two valves inline valves, wherein the dump valve is configured to remove fluid and/or pressure acting upon the inline valves.
Claims20
A pressure relief system for oil and gas operations comprising:
- a first valve on a first line;
- a second valve on the first line;
- a chamber positioned between the first valve and the second valve;
- a dump valve positioned within the chamber being configured to be opened to reduce a first pressure within the chamber, the pressure within the chamber impacts the first valve and the second valve.

A pressure relief system for oil and gas operations comprising:
- a chamber with a dump valve;
- a first valve on a first line, the first valve having a first surface facing a well and a second surface facing the chamber, the first valve being configured to close based on a pressure differential across the valve being greater than a closing threshold, and the first valve being configured to close and form a seal based on the pressure differential across the valve being greater than a sealing threshold, the sealing threshold being greater than the sealing threshold, the dump valve being configured to remove pressure within the chamber to increase the pressure differential from an amount greater than the closing threshold but lower than the sealing threshold to an amount greater than sealing threshold.
