DEVICE FOR HUMIDITY CONTROL OF PIPE LEAKAGE WITH AIR-PERMEABLE THERMAL INSULATION UNDER THE CASING Russian patent published in 2018 - IPC F17D5/02 

FIELD: pipeline system.

SUBSTANCE: invention relates to the field of control of air humidity leakage and can be used in devices for the moisture control of a pipeline leakage with air-permeable thermal insulation under the casing, for example pipelines in cooling circuits of nuclear or thermal power plants. Device for the humidity control of the pipeline leakage with air-permeable thermal insulation under the casing contains an air humidity sensor, upper and lower flow chambers, between which there is a branch pipe. Branch pipe is connected to the cavities of the flow chambers. Lower flow chamber is detachable along the cross-sectional plane, has a central opening for the monitored pipeline and openings for the passage of moist air from the air-permeable thermal insulation. Upper flow chamber is provided with apertures for discharging moist air. Humidity sensor is installed in the upper flow chamber above the upper end of the nozzle.

EFFECT: reduction of the hydraulic resistance to the flow of moist air as it passes to the air humidity sensor and an increase in the useful internal volume for the arrival of moist air from the air permeable thermal insulation into the device for the humidity control of the pipeline leak.
