Abstract
To provide a sensor-equipped joint capable of detecting loosening of the joint positively before leakage of fluid. A seal structure including a joint member forming a flow path and a gasket facing the joint member and forming a seal with respect to the joint member, in which a surface of the joint member facing the gasket includes a first flat surface, an annular seal protrusion protruding from the first flat surface and a second flat surface formed at a position more distant from the gasket as compared with the first flat surface, and a sensor is provided in at least any one of the second flat surface and a part of the gasket facing the second flat surface.

A seal structure comprising:
- a joint member forming a flow path;
- and
- a gasket facing the joint member and forming a seal with respect to the joint member,
- wherein a surface of the joint member facing the gasket includes a first flat surface, an annular seal protrusion protruding from the first flat surface and a second flat surface formed at a position more distant from the gasket as compared with the first flat surface, and
- a sensor is provided in at least any one of the second flat surface and a part of the gasket facing the second flat surface.
A joint comprising:
- a pair of joint members forming a flow path;
- an annular gasket interposed between the pair of joint members;
- and
- a tightening means for connecting the pair of joint members,
- wherein surfaces of the joint members facing the gasket include first flat surfaces, annular seal protrusions protruding from the first flat surfaces and second flat surfaces formed at positions more distant from the gasket as compared with the first flat surfaces, and
- a sensor is provided in at least any one of the second flat surface and a part of the gasket facing the second flat surface.
A closing stopper comprising:
- a joint member forming a flow path;
- a disc-shaped closing plate facing the joint member;
- and
- a tightening means for connecting the joint member and the closing plate,
- wherein a surface of the joint member facing the closing plate includes a first flat surface, an annular seal protrusion protruding from the first flat surface and a second flat surface formed at a position more distant from disc-shaped closing plate as compared with the first flat surface, and
- a sensor is provided in at least any one of the second flat surface and a part of the closing plate facing the second flat surface.
