ABSTRACT:
A housing of a multi-path joint is divided into a plurality of blocks in correspondence with the number of lead-in ports, and a reverse-stop valve for preventing mixed fluid in the main path from flowing backward is provided between the lead-in ports and the main path. Each of the plurality of blocks formed by dividing the housing is provided with a connecting section for positioning when joining to adjacent blocks, and a holding unit is provided for connecting all the blocks in their respective connecting sections and maintaining a connected state between them. According to this multi-path joint, mixed fluid which flowing along the main path, does not flow backward to lead-in ports, and therefore, the atmosphere in the lead-in ports is stabilized. In addition, the multi-path joint is highly functional, being speedily adaptable to the number and shape of the paths on the lead-in port side.
