Claims

[Claims for Utility Model Registration] (1) A primary flow path and a secondary flow path that communicate with the main pipe and the branch pipe, respectively, and an opening/closing part interposed between the primary flow path and the secondary flow path. What is claimed is: 1. A branch valve having a valve box comprising: a main flow passage having a diameter equal to that of the main pipe and communicating with the primary flow passage; (2) A request for registration of a utility model in which the shape of the main flow path and the relative position with respect to the primary flow path and the secondary flow path are set such that the flow path length of the primary flow path is minimized. The branch valve according to item 1. (3) The branch valve according to claim 1 or 2, wherein the opening/closing part has a mechanism equivalent to a springless metal diaphragm valve.
