Title:
PIPE JOINT AND PIPE JOINT SET
Document Type and Number:
WIPO Patent Application WO/2020/255477
Kind Code:
A1
Abstract:
The present invention achieves a pipe joint and a pipe joint set that can achieve a structure limiting the passing flow rate of a fluid that has passed through a flow aperture opened by a valve unit. An upstream-side choke hole of an upstream-side choke section limits the passing flow rate of the fluid. When the fluid flows at a flow rate surpassing the passing flow rate limited by the upstream-side choke hole, the valve unit opens the flow aperture that was closed in the flow path. A downstream-side choke hole of a downstream-side choke section that is positioned on the downstream side of the valve unit limits the passing flow rate of the fluid that has passed through the flow aperture.
