Although the portion of piling up has been got rid of through the structure of above-mentioned connecting seat 26, but still very little relatively because the pipe diameter of second connecting pipe 24 and first connecting pipe 23, still probably take place to block up, so, this embodiment sets up three-way pipe 28, when detecting that the flow sensor rotational speed on a certain return circuit slows down promptly will block up, ultrasonic vibrator 281 vibration through on the three-way pipe 28 makes adnexed precipitate drop, then wash away along with the circulating water, thereby realize automatic clear stifled, make the condition of jam further reduce, and do not need artifical clear stifled, intelligent degree is high, only need regularly to wash whole pipeline.

Water leakage may occur at the connection due to the vibration of the vibrator 281, and an accident may be easily caused when water leakage occurs. As shown in fig. 9 to 10, taking the connection structure of the connection socket 26 and the second connection pipe 24 at the second flow sensor 252 as an example, the present embodiment provides three mounting grooves on the connection socket 26, two of which are provided on the inner wall of the annular notch 261 of the connection socket 26, in which the first sealing ring 262 is fitted, and the other of which is provided on the end of the connection socket 26, in which the second sealing ring 263 is fitted. A pressing portion 241 is provided on the second connection pipe 24 near the edge, and after the second connection pipe 24 is inserted into the connection seat 26, the outer wall of the second connection pipe 24 presses the two first sealing rings 262 to form a radial seal, and the pressing portion 241 presses the second sealing ring 263 to form an axial seal. Further, in the present embodiment, an external thread is provided on an outer wall of the connecting socket 26, and the connecting socket 26 is fixed by the nut 27, which is fitted, and the nut 27 presses the pressing portion 241 to press the second sealing ring 263. Because the axial and radial upward sealing is formed and the multi-stage sealing is adopted, the sealing effect is greatly improved, and the hidden danger of water leakage is avoided.

Further, as shown in fig. 12, in this embodiment, a temperature sensor 29 is disposed between each second connecting pipe 24 and the water outlet pipe 22, and the temperature of the water outlet end of each second connecting pipe 24 is detected, so that if it is detected that the temperature of a certain temperature sensor 29 exceeds the standard, and the first connecting pipe 23 and the second connecting pipe 24 on the branch connected thereto are not blocked, that is, the flow meter operates normally, it can be determined that the water cooling device has a fault, and an alarm is prompted and the time delay is stopped.

Therefore, the cooling system for the control cabinet of the intermediate frequency furnace can automatically clear the blockage when the blockage occurs or before the blockage occurs.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
