BRANCHED COUPLER FOR PIPING OF THERMOPLASTIC MATERIAL

摘要

PURPOSE: To provide a branch connector for piping capable of avoiding an undesirable loss or escaping of a fluid conveyed when it is attached to the piping made of a thermoplastic material and is used for the piping. CONSTITUTION: The branch connector has a seal device 9 provided on an inner wall at an end of a tubular element 5 provided with a closing means 6 and provided in a release housing 10 and is provided with a flexural circular valve 11 disposed in the release housing 11 provided with a circular center portion 14 connected to an outer periphery by a link element 15 and a center opening 17 having a smaller diameter than that of a tool used for boring the piping. The branch connector includes a flexural packing ring 16 mounted to the circular valve 11 and a tightening bush 18 inserted to the release housing 10 in order to retain the circular valve 11 and the packing ring 16 at a predetermined position.
