The technical scheme adopted for solving the technical problems is as follows: the utility model provides a judgement blast furnace tuyere jacket damage monitoring instrument that leaks, including the casing that has the cavity, install inlet tube and outlet pipe on the casing, the cavity intercommunication of inlet tube output and casing, the input of inlet tube is used for the water pipe butt joint with the blast furnace inlet jacket, the input of outlet pipe and the cavity intercommunication of casing, install water inlet valve on the inlet tube, install out water valve on the outlet pipe, install manometer and elastic expansion or shrink's check ball on the casing top surface, but the input of check ball is through the cavity intercommunication of sampling tube and casing, the manometer is used for detecting the pressure in the casing, the casing is installed and is used for detecting the gas detector of carbon monoxide, and the accuracy that judges tuyere jacket leak has been improved greatly to the monitoring instrument, and the rate of accuracy is up to 100%, has reduced the blast furnace damping down that personnel misjudgement brought, has reduced the economic loss that the blast furnace damping down brought.
Further comprising a sampling tube diameter of 12cm.
Further comprises a water inlet pipe which is a metal hose.
The beneficial effects of the utility model are as follows: the monitoring instrument for judging the damage and water leakage of the tuyere small sleeve of the blast furnace, provided by the utility model, has the advantages that the accuracy for judging the water leakage of the tuyere small sleeve is greatly improved by the monitoring instrument, the accuracy is up to 100%, the blast furnace damping down caused by misjudgment of personnel is reduced, and the economic loss caused by the blast furnace damping down is reduced.
