METHOD AND SYSTEM FOR I -SITU VISUAL INSPECTION OF A VALVE

摘要

A method for visually inspecting a valve is provided. The valve controls of a fluid from a first fluid conduit to a second fluid conduit. A tethered imaging device is disposed in the second fluid conduit. The tether extends from inside the second fluid conduit to outside the second fluid conduit. An image capturing end portion of the imaging device is moved in proximity to the valve. A fluid seal for fluid sealing a passage of the tether from inside the second fluid conduit to outside the second fluid conduit is provided. The valve is then at least partially opened and images are captured in-situ of the at least partially opened valve with the valve being exposed to the fluid.
