Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Example 1: as shown in fig. 1, a hot blast valve rapid leak detection device comprises a hot blast valve 1 and a storage pipe 3, wherein a first ball valve 2 and a second ball valve 5 are respectively arranged at two ends of the storage pipe 3, and the storage pipe 3 is communicated with the hot blast valve 1 through the first ball valve 2; the water level leakage monitoring device is characterized by further comprising a transparent pipe 8 used for checking a leakage water level line, two ends of the transparent pipe 8 are communicated with the storage pipe 3 through two three-way pipes respectively, a first quick-connection-peg 7 and a second quick-connection-peg 10 are arranged on one of two three-way pipes of the passage between the two ends of the transparent pipe 8 and the storage pipe 3 respectively, a third ball valve 6 and a fourth ball valve 11 are arranged on the other passage of the two three-way pipes respectively, and the transparent pipe 8 and the storage pipe 3 form a communicating vessel. The third ball valve 6 is arranged on the storage pipe 3 close to the first ball valve 2, and the fourth ball valve 11 is arranged on the storage pipe 3 close to the second ball valve 5. The hot blast valve 1 and the first ball valve 2 are connected through flanges among the storage pipe 3, the first ball valve 2 and the second ball valve 5. The third ball valve 6 and the fourth ball valve 11 are internal thread ball valves. The transparent tube 8 is a PU tube.
Because the valve core cooling water leakage accident is easy to occur in the production and operation of the hot blast valve, the timely, accurate and quantitative detection of the hot blast valve core cooling water leakage condition is extremely important, the device provided by the utility model is installed below the hot blast valve in a flange connection mode, the disassembly is convenient, and the leakage condition can be visually seen in the transparent pipe 8 under the leakage condition of the hot blast valve; simultaneously, owing to reveal liquid storage time of a specified duration, and if reveal that liquid is the pollution liquid, then will increase the pollution and the degree of corrosion of pipeline, so the utility model discloses a first ball valve 2 and second ball valve 5 can easily block storage tube 3, washs or replaces storage tube 3 part, through adopting third ball valve 6 and fourth ball valve 11, easily blocks hyaline tube 8, makes things convenient for washing and the replacement of hyaline tube 8 part. Convenient disassembly and replacement and low cost.
Work as storage pipe 3 intercommunication in the below of hot-blast valve 1, first ball valve 2 and second ball valve 5 set up respectively in the upper and lower both ends of storage pipe 3, more effective, accurate, convenient collection like this the ventilation valve 1 reveal the cooling water.
The utility model discloses normally open at the first ball valve 2 of work, if there is leakage in 1 case of hot-blast valve, ponding 4 flows in storage pipe 3, avoids causing the hot-blast main brick lining to break, and the pipeline reddens, tears, explodes the emergence of different degree accidents such as spouting.
