Title:
THERMO FUSION JOINT
Document Type and Number:
Japanese Patent JP2017187054
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermo fusion joint capable of restricting an abnormal heat generation and restricting its damage while keeping an efficiency of connecting work for resin pipes.SOLUTION: A joint main body 10 is provided with first to fifth connection parts 11 to 15 for use in connecting resin pipes 21, 22. Inner spaces 11a to 15a of the first to fifth connection parts 11 to 15 are communicated to each other through an inner space 10a of the joint main body 10. The first to fourth connection parts 11 to 14 connect flowing-out side resin pipes 21 formed by thermoplastic resin at their outer circumferential parts in the same directions. The inner peripheral parts of the first to fourth connection parts 11 to 14 are formed with the first to fourth thermo fusion parts 31 to 34 of thermoplastic resin. Adjoining connection parts 11 to 14 are arranged in such a way that their thermo fusion parts 31 to 34 are displaced at their positions in the directions of pipe axes X1 to X4.SELECTED DRAWING: Figure 1
