摘要： The present invention relates to a pipe coupling (10) of the type where a pipe (12) is freely insertable into the coupling (14) and where a nut (44) causes engagement of a grip ring (38) and gasket (28) with the pipe (12) to provide a seal between the coupling (14) and the pipe (12) , and where within the coupling (14) there is disposed a stop (16) to indicate to a user inserting the pipe (12) freely that the pipe (12) has been inserted to its required location. The stop (16) is located at a position where there is room beyond the stop (16) for the pipe (12) to move into. Tightening of the nut (44) causes the pipe (12) to move further into the coupling beyond the stop(16) . This solves the problem of the pipe being inserted too deeply into the coupling and being deformed when the nut (44) is tightened further.

摘要： A coupling assembly (10) for plastic pipes (12) including a nut (14), a body (20), a grip-ring (16) and a seal (18). The nut (14) can engage the body (20) through appropriate threads (28) and includes a hooked projection (36) having a sloping surface (46) adapted to abut against and provide a force on a corresponding surface (48) of the grip ring (16) within the body (20). A pipe (12) is inserted through the nut (14), grip-ring (16) and seal (18) into the body (20). Tightening of the nut (14) causes its sloped surface (46) to engage and the grip ring (16) to be forced both radially and longitudinally. Radial compression results in the grip-ring (16) engaging the pipe (12) whilst longitudinal force causes it to be forced into the body (20) simultaneously abutting against and compressing the seal (18) whilst dragging the pipe (12) further into the body (20). The nut (14) and the body (20) may further have tapered surfaces (46) that are brought together as the grip ring (14) is forced into the body (20). The physical connection between the body (20) and the nut (14) provides reinforcing for the nut (14), a feature especially useful when dealing with soft plastics. Further features include a lip (70) on the grip ring (16) that provides an additional support for the grip ring (16) when compressed as well as an abutment shoulder (56) on the nut (14) preventing the grip ring (16) from being pulled out of the body (20).

摘要： The present invention relates to a valve member for a valve of the ball valve type, including two shell parts rigidly joined together to form a valve member and generally snap-fitted over a frame. The two shells have opposed sealing surfaces and a flow passage extends through the shells and the frame. The valve member includes a means for engagement of a drive mechanism to enable rotation of the valve assembly, wherein said valve member can be rotated to present a sealing surface or alternatively rotated to present a flow path to a water supply when said valve member is located in a sealed fluid passage such as a pipe.

摘要： An annular collet (12a) or gripping member radially located within a coupling assembly (10) of the type having a hollow body (18), nut (14) and an O-ring or seal (16) for connection of a pipe (34) thereto. The collet (12a) is axially split, the split (26) defined by first (28) and second (30) generally parallel ends that are of an engageable configuration, typically by one end having a projection and the other end a correspondingly shaped cavity enabling the ends to interlock. In normal operation of the coupling the collet (12a) exerts a longitudinal force on the O-ring (16) causing a seal. When it experiences an axial force that would normally relatively displace the two ends causing a leak, being engaged to each other this movement is resisted ensuring that the seal is maintained. The present invention also relates to a coupling having such a collet.
