Abstract
A pressure control system for controlling pressure in a tank is provided. The pressure control system includes a pressure relief valve and a rupture disc subassembly. The pressure relief valve is connected to the tank. The rupture disc subassembly is located between the pressure relief valve and the tank and is connected to the tank. The pressure relief valve is connected such that removal of the pressure relief valve does not affect the connection of the rupture disc subassembly to the tank.
Claims27
A pressure control system for controlling pressure in a tank having a plate, the pressure control system comprising:
- a pressure relief valve;
- a first bolt extending through the pressure relief valve and into the plate to couple the pressure relief valve to the plate;
- a rupture disc subassembly disposed between the pressure relief valve and the plate, the rupture disc subassembly including two securing plates and a rupture disc disposed between the securing plates;
- and
- a second bolt, independent of the first bolt, extending through the two securing plates and into the plate to removably couple the rupture disc subassembly to the plate, the rupture disc subassembly being removable from the plate from an exterior side of the tank without removing the plate from the tank,
- wherein the pressure relief valve is coupled to the plate such that the pressure relief valve is removable without requiring removal of the coupling of the rupture disc subassembly.
A pressure control system for controlling pressure in a tank, the pressure control system comprising:
- a pressure relief valve having a base;
- a first bolt adapted to extend through the base and into a wall of the tank to couple the pressure relief valve to the tank;
- a rupture disc subassembly disposed between the pressure relief valve and the tank;
- and
- a second bolt adapted to extend through an aperture disposed in the rupture disc subassembly and into the wall of the tank to couple the rupture disc subassembly to the tank, the second bolt being accessible from an exterior side of the tank when the pressure relief valve is removed from the tank,
- wherein the first and second bolts are adapted to be independently coupled to the tank allowing the rupture disc subassembly to remain coupled to the tank when the pressure relief valve is removed from the tank.
A pressure control system for controlling the pressure in a tank, the pressure control system comprising:
- a plate coupled to the tank and having an exterior surface defining an outer surface plane and separating a first region disposed above the exterior surface, and a second region opposite the first region and disposed below the exterior surface;
- a pressure relief valve adapted to be disposed in the first region and coupled to the exterior surface by a valve connector extending through the pressure relief valve and into the plate;
- and
- a rupture disc subassembly adapted to be disposed in the second region and coupled to the plate, by a subassembly connector extending through an aperture in the rupture disc subassembly and into the plate, the rupture disc subassembly adapted to be removable from the plate from an exterior side of the tank without removing the plate, and wherein the pressure relief valve can be removed from the plate while the rupture disc subassembly substantially maintains a pressure within the tank.
