A quick connector assembly and a quick connector device are disclosed. The quick connector assembly includes a first base, a first fluid interface assembly and a valve assembly. The valve assembly regulates whether a fluid flows through the quick connector assembly or not, and thereby sealing the flow of the fluid at both sides of the quick connector assembly. The quick connector assembly and the quick connector device in an embodiment of the present disclosure can regulate the flow of the fluid effectively and provide better barriers to keep concurrent flows separated and isolated. Especially, the quick connector device can be used in slurry delivery system which has fluid being abrasive fluid or solid contained liquid.

A clamp device in various examples facilitates fluid tightness of a subsea pipe ends connection between first and second pipes arranged end to end. Systems, apparatuses, and methods in various examples include pipe adapter devices which couple the clamp device to the arrangement of first and second pipes, the clamp device having first and second clamp members for urging the pipe ends together by varying or setting a spacing between the first and second clamp members along the pipes and actuation means for operating the first and second clamp members to vary or set the spacing.

A gland includes an annular ring, the annular ring defining a gland bore, the gland bore defining a gland axis extending through the annular ring; and a joint restraint assembly, the joint restraint assembly including a restraint base, the restraint base attached to the annular ring, the restraint base defining a restraint pocket, the restraint base including a structural rail; a gripper, the gripper disposed within the restraint pocket and configured to move in the restraint pocket; a spring biasing the gripper to move inwards towards the gland axis; and a cover contacting at least a portion of the restraint base.

Provided is a quick connector assembly for joining a male member and a female connector member together to secure fluid communication in a fluid line system. The quick connector assembly includes a primary latch and a secondary latch configured to toggle between engaged and disengaged positions and to allow for a visual, audible, and/or tactile indication as to the status of a secure attachment between a male member and a female connector member.

Fluid couplings prevent or discourage misconnection of fluid lines. In embodiments, a coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are properly joined. If any of the connectors is not properly mated to a corresponding one, the coupling will leak, since the connectors on each side are joined to a furcating channel. In embodiments, the coupling devices are made unique by providing an arrangement of the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.

A pipe fitting joint assembly including a guide sleeve, provided with a first concave-convex structure on the outer wall of one end thereof, a connecting body, provided with a second concave-convex structure on the inner walls of both ends thereof, and an inner gear ring provided with a third concave-convex structure on an inner ring thereof and a fourth concave-convex structure on an outer ring thereof. The inner gear ring is concentrically inserted into the connecting body. The fourth concave-convex structure and the second concave-convex structure are in interference fit. The guide sleeve is concentrically inserted into the inner ring gear of the connecting body. The first concave-convex structure and the fourth concave-convex structure are in clearance fit therebetween using a moving interference manner.

An improved quick connector with code verification is provided. The quick connector includes a connector body, a connector sleeve, and a sliding lock latch. The connector body includes a verification indicia on its outer surface, and the connector sleeve is movable over the connector body and includes an indicator window that aligns with the verification indicia. The sliding lock latch is moveable from an unlatched position to a latched position through transverse openings in the connector sleeve and the connector body. The sliding lock latch includes first and second wing elements to prevent clockwise and counter-clockwise rotation of the connector sleeve relative to the connector body. The sliding lock latch also includes a locking tab on its outer surface to prevent retraction of the connector sleeve from the connector body.
