摘要： Systems and methods described herein provide for pressure relief valve detection and monitoring. A valve assembly includes a striker and an indicator assembly separated by a diaphragm. The diaphragm may be elastically or permanently deformable. The striker may be connected to a relieve valve disk that releases in response to high fluid pressure at the valve. Movement of the striker may be detected by contact with the diaphragm or by sensors near the diaphragm, which may trigger the indicator assembly to provide an external indication of a valve opening.

摘要： The disclosure describes hydrocarbon flowline corrosion inhibitor overpressure protection. Such a protection system includes a fluid flow pathway fluidically coupled to a corrosion inhibitor injection pump that injections corrosion inhibitor into a hydrocarbon carrying flowline. When the injection pump pressure exceeds a threshold flow pressure, the corrosion inhibitor is flowed through a first branch of the fluid flow pathway to relieve the excess pressure. The first branch is fluidically isolated from a second branch. When a rupture disc in the first branch fails, then the corrosion inhibitor is diverted to flow through the second branch and the first branch is isolated from the corrosion inhibitor flow.

摘要： A valve includes a valve body having an inlet for fluid communication with a space or source containing pressurised gas, and at least one outlet. A membrane is arranged between the inlet and the at least one outlet. A membrane puncturing element is arranged for movement between a retracted, inoperative position and an extended position in which it punctures the membrane. An actuating piston is operatively coupled to the membrane puncturing element for moving the membrane puncturing element between its retracted and its extended positions, the actuating piston being received in a piston bore of the valve body. The valve body also includes a cartridge receiving chamber for receiving a sealed actuating gas cartridge. A cartridge puncturing device is provided for puncturing the actuating gas cartridge. An actuating gas flow passage communicates actuating gas released from the actuating gas cartridge to the actuating piston bore upon puncturing the actuating gas.

摘要： A high pressure fluid system including enhanced safety, maintenance and servicing features. The system can include a CAM assembly module, having a valve seat assembly, seal cartridge assembly and inlet manifold, that is easily installed in and removed from a frame and/discharge manifold as a single unit. A discharge manifold can isolate different pressure rated passageways of the system, and multiple rupture discs associated with the same. A discharge manifold end plate can be included to provide ease of repair of discharge outlets and to establish a plumbing system for the rupture discs. A quick coupler can facilitate connection between a plunger of the seal cartridge assembly and a cross head stub connected to a power frame. A lubrication valve assembly can provide and meter lubrication from a high pressure inlet source to a plunger and packing of the seal cartridge assembly.

摘要： A liquid-to-vapor conversion device includes a chamber having an opening connected to a liquid intake, a pressure relief opening, and a vapor outlet. The device also includes a flow controller arranged at the level of the liquid intake, and a burst disk installed at the level of the pressure relief opening. Further, the device includes pressure-limiting means arranged at the level of the liquid intake. The pressure-limiting means is configured to decrease the flow rate in the liquid intake when the pressure in the liquid intake exceeds a threshold value smaller than a bursting pressure of the burst disk.
