PRESSURE RELEASE VALVE FOR OIL RECOVERY SYSTEMS

摘要

The disclosure relates to a pressure release valve (100). The pressure release valve may be suitable for use as an oil recovery valve. In one embodiment, the pressure release valve may comprise a piston (5) and tube (4) configured to slide within a valve body, wherein the piston is configured to remain sealingly engaged with the tube until the pressure release valve fully activates. Upon activation, the piston may disengage from the tube, thereby allowing fluid to escape from the valve through the tube.

1. A pressure release valve, comprising:
a valve body defining a first bore and a second bore, the valve body further defining a fluid flowpath; a piston having a first end, wherein the piston is configured to slide within the first bore; a tube having a second end, wherein the second end of the tube is configured to sealingly engage with the first end of the piston, wherein the tube is further configured to slide within the second bore while the second end and first end are sealingly engaged; wherein the first end of the piston is configured to disengage from the second end of the tube upon activation of the valve; and wherein the tube is configured to transmit fluid to the fluid flowpath when the first end of the piston is disengaged from the second end of the tube.
