摘要： In some implementations, a flowline connector assembly may include a first flowline member having a first cylindrical passageway, and a second flowline member having a second cylindrical passageway. The flowline connector assembly may include a pin, configured to be inserted into the first cylindrical passageway and the second cylindrical passageway, including a stop extending radially outward from an outer surface of the pin, where a first side of the stop is configured to contact a face of the first flowline member when the pin is inserted into the first cylindrical passageway. The flowline connector assembly may include a collar configured for threaded engagement at a first end with an outer surface of the first flowline member, wherein an inner surface of the collar is configured to contact a second side of the stop to connect the first flowline member with the second flowline member.

摘要： A plug valve including a valve body defining an internal cavity, a first passage, and a second passage, a plug defining a third passage and being rotatable within the internal cavity, and an insert extending within the internal cavity between the valve body and the plug. The insert defines an interior surface and an opening aligned with the first passage of the valve body. The insert may also define a sealing surface extending around the opening and standing in relief against the interior surface to sealingly engage the plug. In addition to, or instead of, the sealing surface, the insert may define a projection at least partially defining the interior surface. In addition, a boot may be connected to the valve body and interlocked with the projection to prevent, or at least reduce, rotation of the insert relative to the valve body when the plug rotates within the internal cavity.

摘要： A fluid end of a reciprocating pump assembly includes a cylinder, a cover, and a valve stop. The cylinder has a fluid inlet, a fluid outlet, and an access side wall comprising an access wall inner surface that defines an access opening. The access opening provides access to an inner area of the cylinder and has an access opening axis. The cover is positioned in the access opening and forms a seal with the access wall inner surface along the access opening. The cover includes a cover axis coaxial with the access opening axis. The valve stop is positioned partially in the fluid inlet and includes a spring retainer and a column portion. The column portion includes a flange positioned between the cover and the access wall inner surface. The flange is in the shape of an arc.
