    摘要： Accessory (1) for repairing a pipe by welding comprising at least two arms, each arm in turn comprising an end mouth (31, 32, 33) for receiving a pipe and a stop (41, 42, 43) for limiting the insertion of said pipe into the accessory. Each arm comprises an end section (21, 22, 23) for receiving the pipe and an inner section (11, 12, 13). The stop (41, 42, 43) is arranged between the end section (21, 22, 23) and the inner section (11, 12, 13). In each arm, the internal diameter of the end section (21, 22, 23) is greater than that of the inner section (11, 12, 13), and the length of the inner section (11, 12, 13) is equal to or greater than the length of the end section (21, 22, 23).

    摘要： A double containment fitting for engagement with double containment pipes and comprising a one-piece integral structure having at least one outer cylinder having at least two outer receiving openings, at least one inner cylinder having at least two inner receiving openings, and a plurality of ribs integral with and spacing the at least one outer cylinder from the at least one inner cylinder, thereby forming an inner fitting flow area within the inner cylinder and forming an outer fitting flow area between the at least one outer cylinder and the at least one inner cylinder and between adjacent ribs. Each inner tube of the double containment pipes are connected to the double containment fitting by being located within one of the inner receiving openings. Each outer tube of the double containment pipes are connected to the double containment fitting by being located within one of the outer receiving openings.

    摘要： A locking quick connect assembly is provided for removably coupling a first tube and a second tube. A quick connect housing presents a central bore for receiving the second tube. A redundant latch component positionable between an unlocked position and a locked position may be provided to slidingly engage the quick connect housing. A twist lock retainer surrounds the quick connect housing and the redundant latch component. The redundant latch component includes an axially extending latch retaining arm and the twist lock retainer includes a locking channel for receiving the latch retaining arm. The twist lock retainer also includes a twist lock retaining arm that locks against a bead of the second tube to resists separation. The twist lock retaining arm extends transversely to and radially inwardly of the locking channel to engage the latch retaining arm to prevent unwanted decoupling of the assembly. A handle extends from the redundant latch component in a direction opposite the latch retaining arm.

    摘要： A branching tool (20) serving as a check valve incorporated in a cleaner device includes: a main unit (26) provided with an inflow channel (22) and a first outflow channel (24a); a sealing member (30) that allows a flow of cleaning fluid from the inflow channel (22) to the first outflow channel (24a) when the cleaner device is in operation and that is formed to seal a backflow of the cleaning fluid from the first outflow channel (24a) to the inflow channel (22) when the cleaner device is not in operation; and a lid member (28) that is combined with the main unit (26) so as to form a housing chamber (34) for the sealing member (30). The lid member (28) has a communication hole (40) that allows the housing chamber (34) to communicate with the outside. The lid member (28) or the main unit (26) is provided with a water receiving recess (42) arranged around the communication hole (40).
