An embodiment of a fire-suppression water-intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire-suppression water-intake valve can allow quick and easy removal and installation of a fire-suppression sprinkler head without shutting a water supply to the valve.

The present disclosure discloses a connector. The connecter includes a housing; a pipe at least partially disposed in the housing; and a base mounted to a first item and disposed to the housing to allow the housing to float between a first longitudinal position and a second longitudinal position relative to the base, such that the pipe is connected to a second item in a floating manner along the longitudinal direction.

The present disclosure relates to a connecting apparatus for connecting fluid-conducting lines comprising a first fluid-conducting line having a first connecting section, a second fluid-conducting line having a second connecting section, and a retention collar for fixing the connecting sections together. The second connecting section can be introduced axially into the first connecting section to provide a fluidic connection between the first and second fluid-conducting line. The retention collar has first retaining projections designed to engage into a first locking contour on the outer surface of the first fluid-conducting line. The retention collar has second retaining projections designed to engage into a second locking contour on the outer surface of the second fluid-conducting line. The first retaining projections engage into the first locking contour. The second retaining projections engage into the second locking contour to limit an axial displacement of the first connecting section relative to the second connecting section.

A downspout adapter includes a first part. The first part includes a mouth portion and a hollow structure extending from the mouth portion. The hollow structure includes at least one ratchet member and at least one recessed portion. The downspout adapter includes a second part configured for receiving the hollow structure therein. The second part includes at least one protruding member configured to removably engage with a corresponding recessed portion of the at least one recessed portion while the hollow structure is inserted within the second part. The second part includes at least one engaging member including an engaging end configured to selectively engage with a plurality of teeth of the at least one ratchet member while the hollow structure of the first part is inserted within the second part, thereby detachably coupling the second part with the first part.

A coupling member for a blind mate fluid coupling includes a housing and a valve body that is self-centering and alignable relative to the housing. The valve body may include at least two radial shoulder portions or abutments that are configured to engage at least two corresponding radial abutments of the housing to improve self-centering when in a decoupled state. A biasing member may urge the valve body abutments against the corresponding housing abutments to compensate for misalignment and/or provide self-centering in both a decoupled and mated state.

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.

An exemplary bulkhead connector assembly may include a housing that has an inner diameter surface, a first opening and a second opening. The assembly may further have a retainer attached to the housing and one or more feet extending radially inward from the inner diameter surface of the housing. The assembly can also include a collar that has a portion received within the first opening or the second opening. The collar may have an outer surface that cooperates with the feet of the retainer to hold a conduit within the housing.

A fitting for use in a manifold or other tubular assembly includes a core and at least one tubular coupling sleeve slidably and sealingly fitted over a distal end of the core to accommodate predetermined tolerances in the relative positions of fluid ports connected with the tubular assembly. Features are provided to limit the range of motion to the predetermined tolerances and to prevent disassembly of the coupling sleeve from the core of the fitting.

A blower pipe comprises an intermediate pipe (a second pipe) including a circumferential positioning groove and an axial positioning groove, and a proximal pipe (a first pipe) including a first projection and a second projection on an outer peripheral surface thereof. The proximal pipe is connected to the intermediate pipe with the distal end portion of the proximal pipe being inserted in a proximal end opening of the intermediate pipe, the first projection being engaged with the circumferential positioning groove in a circumferential direction of the intermediate pipe, and the second projection being engaged with the axial positioning groove in an axial direction of the intermediate pipe.
