초록 ▼

Apparatus and method for detecting fluid leakage into an enclosed leakage chamber or space sealed by a fluid seal exposed to pressurized fluid from a flow line or pressure vessel. Upon leakage of fluid from the flow line or pressure vessel past the seal into the leakage chamber or space, the leaked fluid is communicated to a piston chamber in a fluid indicator device. Upon the reaching of a predetermined high fluid pressure, the piston is actuated for extending an indicator rod of the fluid indicator into a projected position for visual observation. For testing or inspection of the leaked fluid, a separate removable adaptor is provided for moving the piston to a fluid bypass position to permit removal of fluid from the piston chamber containing the leaked fluid, or to permit injection of an external fluid such as a sealant into the piston chamber and leakage chamber.

대표청구항 ▼

Apparatus for detecting fluid leakage past a fluid seal into an enclosed leakage chamber sealed by said fluid seal and comprising: a fluid device having an inlet chamber in fluid communication with said leakage chamber and a piston in continuous fluid communication with fluid pressure in said inlet chamber adapted to be moved from a first normal set position to a second position upon the reaching of a predetermined fluid pressure in said inlet chamber to provide an indication of fluid leakage; and separate means selectively operable to provide fluid communication serially with said inlet chamber and said leakage chamber after movement of said piston to said second position thereby to permit direct fluid communication between said separate means and said inlet chamber, said separate means including means to move said piston to a third position to permit fluid to bypass said piston from said leakage chamber to said separate means.
