The bottom of described tank body 1 is provided with described water inlet pipe 2, and the middle part of described tank body 1 is provided with described rising pipe 3; The top of described tank body 1 is equipped with described vapor pipe 4, and described vapor pipe 4 is a Y-tube, and described vapor pipe ball valve 5 is installed on its side pipe, described CO is installed on pipe on it detects ball valve 6, and its lower pipe is connected with the top of described tank body 1; Described CO detection probe 7 and CO measuring element and display screen 8 also are installed on upper pipe, and by a N
2Scavenging pipeline connects described N
2Bottle 11, this N
2Described N is installed on scavenging pipeline
2Purging ball valve 10; The both sides of described tank body 1 are equipped with the handle 9 of being convenient to guide and support.
In technique scheme, described tank body 1 comprises cylindrical tank and vertebra shape tank deck, and described taper tank deck and described cylindrical tank link together; Described rising pipe 3 is positioned at the top of described cylindrical tank.
The utility model has the advantage of:
1, high safety, during leakage detection, cooling stave is not cut off the water supply, and prevents from the cooling wall breakage aggravation or burn out not damaging cooling stave;
2, accuracy is high, and the airtight environment CO that is not subjected to of CO proofing unit affects;
3, removable, install light movement convenient; Cheap, tank body adopts iron sheet or steel sheet to make;
4, easy to use, can a people complete the leakage detection operation.
