    Abstract: A pressure relief valve system for use in a downhole operation may include a pressure relief valve configured to relieve pressure from high pressure tubing extending between a pump and a wellhead, and may include a sensor operably disposed to detect pressure in the high pressure tubing. The pressure relief valve system also may include a controller 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 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.

    Abstract: A plug valve including a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port. The valve also includes an inlet seal segment within the central chamber and includes a bore extending therethrough and aligned with the inlet port. An outlet seal segment is disposed within the central chamber having a bore extending therethrough and aligned with the outlet port. A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.

    Abstract: A swivel joint has uniform ball bearing requirements for all bearing races. The swivel joint has a male connector and a female connector that coaxially interconnects and swivel relative to each other while still maintaining a high pressure seal. Each connector has three bearing races to form three sets of bearing races, each of which supports the same number of ball bearings. The circumference of the main set of races are enlarged by less than the diameter of one ball, so it is impossible to add another ball to the coupled male and female connectors of the swivel joint.

    Abstract translation: 旋转接头对所有轴承座均具有均匀的球轴承要求。 旋转接头具有阳连接器和阴连接器，其同时在保持高压密封的同时彼此相互连接和旋转。 每个连接器都有三个轴承座，以形成三组轴承座圈，每个轴承座支撑相同数量的球轴承。 主要组合的圆周比一个球的直径增加，因此不可能在旋转接头的耦合的阳和阴连接器上添加另一个球。

    Abstract: A fluid end 15 for a multiple reciprocating pump assembly 12 comprises at least three plunger bores 61 or 91, each for receiving a reciprocating plunger 35. Each plunger bore has a plunger bore axis 65 or 95. The plunger bores are arranged across the fluid end to define a central plunger bore and lateral plunger bores located on either side of the central plunger bore. The fluid end 15 also comprises at least three respective suction valve bores 59 or 89 in fluid communication with the plunger bores. Each suction valve bore can receive a suction valve 41 and has a suction valve bore axis 63 or 93. The fluid end 15 also comprises at least three respective discharge valve bores 57 or 87 in fluid communication with the plunger bores. Each discharge valve bore can receive a discharge valve 43 and has a discharge valve bore axis 63 or 93. At least one of the axes of at least one of the suction and discharge valve bores is offset in the fluid end from its respective plunger bore axis.
