摘要： A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides an internally restrained pipe joint including a bell with a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of toothed, rigid restraining segments is at least partially embedded in the gasket.

摘要： An apparatus for connecting two pipes in fluid communication includes a connector body having opposing open ends with each open end configured for receiving a free end of a pipe. A mechanical interlock arrangement prevents or limits axial movement of the connector body relative to a free end of a pipe when the free end of the pipe is received in an open end of the connector body. A mechanical seal arrangement provides a metal-to-metal seal between a pipe inserted into one of the open ends and the connector body.

摘要： A multi-lumen surgical utility connector is configured to receive two or more utilities from a surgical utility supplying device. The multi-lumen surgical utility connector may be connected to a utility port of the surgical utility supplying device which supplies two or more utilities. The multi-lumen surgical utility connector may include a Radio Frequency Identification (RFID) tag which identifies the type or model of multi-lumen surgical utility connector. The surgical utility supplying device may determine the type and parameters of utilities to be supplied through the multi-lumen surgical utility connector based on information read from the RFID tag.

摘要： The present invention relates to a shower head adapter connected between a main shower head body and a hose. To this end, the shower head adapter according to one embodiment of the present invention comprises: a body part, which has one side connected to the inner circumferential surface of the inlet side of a main shower head body and the other side connected to a hose, also has a first circular groove formed along the outer circumferential surface thereof, and forms a flow channel passing through the other side; a main body connecting part, which shares the flow channel with the body part and has an end on the other side protruding inwards from the inner circumferential surface thereof, wherein a part of the inner circumferential surface is coupled to the outer circumferential surface of the inlet side of the main shower head body; and a snap ring, which is inserted in the first circular groove, and the diameter of the outer circumferential surface of which is larger than the diameter of the protruding inner circumferential surface of the main body connecting part, and which thus prevents the main body connecting part from being separated from the body part in case of a force acting in the direction from the other side to the one side of the body part.

摘要： Systems, methods and components for a tool-less, pre-assembled restrained joint for a pipe are disclosed. For example, a pipe can include a tubular member having an axis, a spigot on one axial end, a bell on an opposite axial end, an outer retainer groove in an outer surface of the spigot, and an inner retainer groove in an inner surface of the bell. A retainer comprising a split ring can be configured to be mounted in the inner retainer groove. The retainer can include a single annular finger cantilevered therefrom and circumscribing an entirety of the split ring in spring bias. The finger can be configured to engage the outer retainer groove of a second pipe in a pipe assembly.

摘要： A shape memory alloy (SMA) sealing ring is deformed to provide a shape between a radially inner sealing portion and radially outer sealing portion thereof which has at least one peak and at least one trough. When the shape memory behavior of the SMA is activated, this shape provides a sealing connection between a first and second member.

摘要： A connection arrangement includes a first connection body and a second connection body for forming a pneumatic connection along a connection axis, and a sealing element configured to seal a sealing gap which surrounds the pneumatic connection and which has a longitudinal dimension which extends parallel to the connection axis. A pneumatic flow is able to travel through the first and second connection bodies along the connection axis. The first connection body has a through-hole having a cross section transverse to the connection axis. The second connection body is arranged at least partially in the through-hole. An at least partially circumferential first recess transverse to the connection axis is formed on an outer face of the first connection body extending parallel to the connection axis for receiving the sealing element.
