No-Crimp Valve Assembly
A no-crimp valve assembly employs a fitting which has an enlarged outer portion and a coaxial inner portion of reduced diameter. An axial groove is formed between the outer portion and the inner portion for receiving the end of a polymer pipe. A nut retainably receives a split ferrule. The split ferrule has a serrated inner surface. The nut is threaded to the outer threaded surface of the outer portion and the ferrule is compressed against the outer surface adjacent the end of the pipe to form a fluid tight connection and the inner surface of the pipe engages the reduced surface of the inner portion. In some embodiments, the inner portion carries one or more sealing rings or has a serrated or stepped inner surface which engages the inside surface of the pipe.
APPLIANCE END FITTING
An end fitting for use in connecting a gas source in fluid communication to an appliance, includes a nut mounted by a fusible and meltable heat activatable material on a socket having a chamber for receiving a plug. The plug connects to the gas source and the socket connects to the appliance. An O-ring of meltable heat activatable material separates the plug and socket. The socket includes a spring that biases a valve member against the plug and between closed and open conditions, respectively, to block or permit fluid flow from a source and through the chamber. In case of excess heat buildup in the socket body, the heat activatable materials melt but unless the gas source is turned off always allow a predetermined amount of gas to flow.
DELIVERY OF CHEMICALS
A chemical delivery system connects to a chemical tank and includes a union connected to the tank outlet and providing an antirotation feature, in addition to threads, to prevent rotation of the assembly in response to asymmetric loads. A measuring tube alternately receives liquid from the tank and is isolated from the tank. While isolated from the tank, liquid is withdrawn from the tube by a pump under conditions allowing the pump to be calibrated. The assembly is cantilevered from the tank outlet and is of reduced length and weight producing a device which is not prone to overstress the tank outlet.
Integrated manifold and valve assembly
An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.
Tapping sleeve with bent ends
A tapping sleeve includes a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange defined between the first side and the first bend line; a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange defined between the second side and the second bend line; and an arcuate portion formed between the first bend line and the second bend line.
ASEPTIC CONNECT AND DISCONNECT COUPLER
A coupler for aseptically coupling and controlling fluid communication between at least two components. The coupler includes a first connector housing with an inner concave surface. A first connector extends from the top of the first connector housing and is adapted to connect to a first component. A first connector conduit extends through the first connector and into the first connector housing so as to define a fluid passageway to an inner opening on the inner surface of the first connector housing. A rotary valve is located within an inner cavity of the first connector housing and includes at least two rotary valve segments. The rotary valve segments are configured to rotate within the cavity. At least one of the rotary valve segments includes a fluid conduit extending through the at least one rotary valve segment.
UNDER-PRESSURE TAPPING AND ACCESS ASSEMBLY FOR PRESSURIZED PIPE
An under-pressure tapping and access assembly is provided for use with a pressurized pipe. The under-pressure tapping and access assembly includes a multi-branch portion sealingly coupled to an outer surface of the pressurized pipe. A tapping branch of the multi-branch portion extending along a tapping branch axis that is substantially perpendicular relative to a pipe axis of the pressurized pipe. A first access branch of the multi-branch portion extending along a first access branch axis that is non-perpendicular relative to the pipe axis. A tool is sized for insertion through the first access branch.
SPRING ADJUSTABLE HANDLE FOR FAUCET VALVE ASSEMBLY
A valve assembly of a faucet includes a valve body, a valve cartridge received within the valve body and including a valve stem defining a longitudinal axis, and a handle operably coupled to the valve stem of the valve cartridge. Illustratively, a spring biases splines of a valve stem adapter downwardly into engagement with splines of the valve stem.
ADJUSTABLE MULTI-PORT CONNECTOR AND VALVE
A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.
WATER DISTRIBUTION
A water distribution pipe comprises an elbow formation along its length, an aperture-defining formation defining an aperture in a radially distal wall of the elbow formation along a radius of the curvature of the elbow, and an openable closure that is mounted or mountable to the aperture-defining formation and that closes the aperture.
