[0002] The water jacket flowmeter of the metallurgical furnace is a key equipment for monitoring the state of the circulating cooling water in the production process of the metallurgical furnace, and when the water jacket flowmeter is damaged, the pipeline needs to be shut down for treatment. Due to the limitation of the space on site, the water jacket flowmeter is compactly installed in the upper or lower area of the water tank, resulting in that the tool for replacing the flowmeter is limited by the environment, and the installation and disassembly are difficult, and the work efficiency is low. The furnace may not be effectively cooled for a long time, and thus the safe and stable operation of the metallurgical furnace is affected.

[0003] Through online and offline search, no suitable tool for replacing the water jacket flowmeter is found. At present, the wrench and the pipe wrench are usually used for replacing the water jacket flowmeter. When the water jacket flowmeter is replaced, the two tools can effectively twist the connecting screw, but are affected by the constraint force of the upper and lower pipelines, cannot expand the effective installation space, and will also cause the upper and lower pipeline interfaces to be misaligned, which makes it very difficult to disassemble and install the water jacket flowmeter. Usually, two people are needed to expand the upper and lower pipelines and align the upper and lower pipeline interfaces, and one person replaces the water jacket flowmeter.

[0008] Further, the L-shaped support rod comprises a vertical section and a horizontal section, the vertical section is connected with the screw rod of the basket bolt, and the horizontal section is fixedly connected with the fixed ring.

[0009] Further, the horizontal section of the L-shaped support rod is welded with the fixed ring.

[0010] The design principle of the utility model is as follows:

[0011] The utility model discloses a special tool which is designed and manufactured in combination with the problems existing when replacing water jacket flowmeter on site, and the tool body mainly consists of two parts, one is to select the basket bolt with adjustable length as the main part, and the basket bolt is redesigned according to the force requirement on site, the second is to select the appropriate clamp for fixing the pipeline, and one holding ring is welded at the upper and lower ends of the basket bolt respectively, and the holding ring is at a certain distance from the double basket bolt to leave enough space for the water jacket flowmeter, and the third is to select the different specifications of the inner lining ring in the holding ring to meet the use requirement of all water jacket flowmeters on site.

[0012] When replacing the water jacket flowmeter, the water jacket flowmeter connecting screw is loosened, the upper and lower clamps of the tool are fixed on the upper and lower pipelines of the water jacket flowmeter, then the length is adjusted by rotating the basket bolt, so that the upper and lower pipelines of the water jacket flowmeter are expanded, and the water jacket flowmeter is conveniently disassembled, the upper and lower pipeline directions are fixed through the clamp, the upper and lower interfaces are prevented from being dislocated, and the water jacket flowmeter is conveniently installed.

[0013] The utility model has the advantages that:

[0014] The tool needs at least 30 minutes before use to replace the water jacket flowmeter, and through the development and on-site use of the tool, the time for replacing the water jacket flowmeter is shortened to within 15 minutes. The introduction of the new tool will solve the operation difficulty of replacing the water jacket flowmeter, effectively shorten the time required in the whole replacement process, and ensure the high efficiency and safety of the maintenance work.
