This disclosure relates to an irrigation system pipe joint or span coupling, which can connect a span of an irrigation system to another structure. In examples, the joint can include various components that attach an end of a first pipe or joint to an end of a second pipe or joint. For example, the end of the first joint can include a receiver plate, which can include a recess with a bushing. In addition, the end of the second joint can include a post, hook, or other elongated member that, in order to connect the first joint to the second joint, is insertable into the bushing.

An exemplary bulkhead (104A) connector assembly (100) includes a housing (106) having a first opening (138) and a second opening (130). The assembly (100) may further include a collar (108) that has a portion received within one of the first and second openings. The collar (108) may be rotatable to a latched position to hold a conduit (104B) within the housing (106). Further, the assembly (100) may have a detent (118) holding the collar (108) in the latched position when the detent (118) is moved to a locked position. The detent (118) in the locked position may have an indicator surface (112) providing tactile feedback indicative of the detent (118) holding the collar (108) in the latched position.

This connection plug (14A, 14B; 14) includes a connecting plate (18) equipped with at least a passage channel (46) centered on a central axis (X46), at least one fluid coupling element (20A, 20B) able to be fluidly coupled with an external fluid coupling element of a cold plate. The fluid coupling element is movable (M1), in a housing of the connecting plate, with respect to the passage channel of the connecting plate for misalignment compensation of the fluid coupling element while being in fluid communication with the passage channel. This connection plug also includes a support member (22) able to be fixed with respect to an internal channel (16) for a fluid communication between the internal channel and the passage channel. The connecting plate (18) is movable (M2) with respect to the support member (22) along a principal axis (T) transverse to the central axis (X46) of the passage channel (46). This connection plug (14A, 14B; 14) also includes a spring (34) designed to elastically push the connecting plate with respect to the support member along the principal transverse axis towards a position in abutment against an internal surface of the support member.

This coupling element has a body and a nozzle. The body delimits a housing for partially receiving the nozzle. The nozzle has a tubular part and a flange received in the housing. Two sealing barriers formed by at least one sealing joint are interposed between a rear surface of the flange and a front face of the body, between a front surface of the flange and a rear face of the body, respectively. A plug caps an inner conduit. Portions of the inner conduit communicate through at least one passage opening into an inner volume of the nozzle, forward of the plug, and on an outer peripheral surface of the flange. An inner chamber is separated from the inner conduit by the body, the flange, the plug and the first sealing barrier.

What is disclosed is an improved irrigation-system-coupling device, with a length-adjustment feature, that is designed to provide a coupling between polymeric irrigation-system hosing/tubing and a water-supply valve, such as solenoid-operated control/supply valves commonly used in automated irrigation systems. The length-adjustment configuration allows for easy installation in the field without the need to splice additional lengths of hosing/tubing in situations where various environmental conditions and/or necessitated repairs to or removal of sections of hoses/tubing has caused an extra gap between a supply-valve manifold housing and the end of the existing hose/tubing.

Art aircraft fluid line coupling assembly includes: an inner tube; an outer tube assembly having an outer tube, the inner tube extending into the outer tube, and having first connector element of a twist-to-connect joint disposed on a front end of the outer tube; a retention member having second connector element of the twist-to-connect joint, the first and the second connector elements being detachably mated to releasably interconnect the retention member and the outer tube with each other, the retention member being arranged outwardly around a longitudinal portion the inner tube so as to prevent detachment of the inner tube from the outer tube when the twist-to-connect joint is in a connected position, and so as to allow detachment of the inner tube from the outer tube when the twist-to-connect joint is in an unconnected position; and a locking mechanism for locking the twist-to-connect joint.

A transfer coupling includes a static component and a rotatable component arranged concentrically, the static component including a first number of radially extending ports and the rotatable component having a second number of radially extending ports the radially extending ports arranged in a common circumferential plane wherein the ports are configured and arranged, in use, to homogenise a flow area for a fluid being transferred through the ports and thereby create a homogenous volume flow.
