    Abstract: A pressure relief valve assembly includes a rupture disc that is shaped to only be inserted into a particular rupture disc cavity in the correct way. The rupture disc includes a cylindrical rupture disc stem and a radially protruding upper lip. A relief valve body in the pressure relief assembly includes an internal radial shoulder at the entrance of the rupture disc that is narrower than the protruding upper lip of the rupture disc but that is wider than the rupture disc stem. The shoulder allows only the rupture disc stem to be inserted into the rupture disc cavity, not the protruding upper lip. Optionally, the relief valve body is marked with some indicia to indicating the direction of inserting the rupture disc stem and/or a shrapnel catcher for trapping shrapnel of the rupture disc upon rupturing.

    Abstract: The valve member includes a valve body and a seal. The valve body defines a first frusto-conical surface and an outside annular cavity. The seal extends within the outside annular cavity and includes a first tapered and circumferentially-extending surface adapted to sealingly engage the tapered surface of the valve seat. In another aspect, the seal includes an annular bulbous protrusion from which the first tapered and circumferentially-extending surface angularly extends, the first tapered and circumferentially-extending surface extending between the annular bulbous protrusion and the first frusto-conical surface of the valve body. In another aspect, an offset distance is defined between the first frusto-conical surface of the valve body and at least a portion of the first tapered and circumferentially-extending surface of the seal, the offset distance extending in a direction that is perpendicular to at least the first frusto-conical surface of the valve body.

    Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to sliding surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of rolling surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.

    Abstract: A pressure relief valve system (150 or 500) for use in a downhole operation may include a pressure relief valve (152) configured to relieve pressure from high pressure tubing (116) extending between a pump (112) and a wellhead (114), and may include a sensor (158) operably disposed to detect pressure in the high pressure tubing. The pressure relief valve system also may include a controller (162) having a pressure threshold stored therein. The controller may be configured to receive data from the sensor and compare the detected pressure to the stored pressure threshold. A valve actuation system (156, 402, or 514) may be in communication with the pressure relief valve and in communication with the controller. The valve actuation system may be configured to change the state of the pressure relief valve from a closed state to an open state in response to a command signal from the controller.
