  • Patent number: 11428325
    Abstract: A rotatable pressure relief valve assembly is provided. The assembly may comprise a butterfly valve, a spring actuator, and a diaphragm device having a flexible membrane. A linkage assembly may be provided with a first end and a second end, wherein the first end may be configured to engage with a terminal end of a piston of a spring actuator, and wherein the second end may be configured to engage with a latch arm of the diaphragm device. A pilot tube may be configured to transmit an inlet fluid pressure from the inlet side of the butterfly valve to the sealed chamber. The assembly may further comprise a buckling pin mechanism having a buckling pin. The diaphragm device may be configured to translate the inlet fluid pressure into a compressive force and to transmit the compressive force to the buckling pin, and the latch arm may be configured to disengage from the second end of the linkage assembly when the buckling pin has buckled.
