[0023] In order to make the purpose, technical scheme of the utility model carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the figure to the utility model embodiment carries out further detailed explanation. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all embodiments, only to explain the embodiments of the utility model, and not for limiting the embodiments of the utility model, all other embodiments obtained by the ordinary skill in the art without doing creative work belong to the scope of the utility model protection.

[0024] Embodiment one, please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of automatic exhaust mechanism of oil return pipe for online monitoring device, shell 2 is fixed outside online monitoring instrument main body 1, the inner wall of shell 2 is equipped with fan blade 12, the wind that fan blade 12 blows can speed up the cooling rate of high-temperature oil liquid, radiator 4 and resistance heater 11 are fixed in the inner wall of shell 2, resistance heater 11 is powered, since resistance heater 11 is fixed in the first curved pipe 8, so when oil liquid enters the first curved pipe 8 from oil return port 10, resistance heater 11 will heat oil liquid, condenser pipe 5 is fixed in the lower end of radiator 4, radiator 4 will cool down condensing agent in condenser pipe 5, realize the circulation use of condensing agent.

[0025] Oil return pipe 9 includes oil storage port 6, exhaust chamber 7, first curved pipe 8, oil return port 10 and second curved pipe 13, exhaust pipe 15 is fixed on the upper end of exhaust chamber 7, one-way valve 16 is fixed on the inner wall of exhaust pipe 15 near port, since temperature rises and pressure becomes large, so internal and external pressure difference will push open one-way valve in exhaust pipe 15, and the gas that floats in oil liquid is discharged to the outside of online monitoring instrument main body 1 by exhaust pipe 15.

[0026] On the basis of embodiment one, in order to realize the automatic exhaust function of oil return pipe 9, fan blade protection shell 3 is fixed on the outer surface of shell 2, fan blade protection shell 3 is communicated with the inside of shell 2, fan blade 12 is equipped on the inner wall of fan blade protection shell 3, condenser pipe 5 corresponds with fan blade 12, condenser pipe 5 is located in front of fan blade 12, the wind that fan blade 12 blows can speed up the cooling rate of high-temperature oil liquid.

[0027] Radiator 4 is located on the inner wall surface of shell 2 above fan blade 12, radiator 4 will cool down condensing agent in condenser pipe 5, realize the circulation use of condensing agent, oil return pipe 9 is fixed on the inner wall surface of shell 2 with fan blade 12 same side.

[0028] The second curved tube 13 is fixed inside the condenser tube 5. Since the second curved tube 13 is fixed inside the condenser tube 5, the low-temperature refrigerant inside the condenser tube 5 will cool down the high-temperature oil in the second curved tube 13. The resistance heater 11 is fixed inside the first curved tube 8. Since the resistance heater 11 is fixed inside the first curved tube 8, when the oil enters the first curved tube 8 from the oil return port 10, the resistance heater 11 will heat the oil. The corresponding ports of the first curved tube 8 and the second curved tube 13 are fixedly connected to the two sides of the exhaust chamber 7.

[0029] The second curved tube 13 has an oil storage port 6 at its end. The second curved tube 13 is U-shaped, which greatly increases the residence time of the oil inside the second curved tube 13. Together with the fan blade 12, it cools the high-temperature oil to room temperature. The oil storage port 6 is located outside the condenser tube 5. The first curved tube 8 has an oil return port 10 at its end. The first curved tube 8 is U-shaped, which greatly increases the residence time of the oil inside the first curved tube 11, allowing the oil to be heated to a sufficient boiling temperature. The oil return port 10 does not have a resistance heater 11 inside.

[0030] A conical outer shell 14 is fixed to the upper end of the exhaust chamber 7, and an exhaust pipe 15 is fixed to the upper end of the conical outer shell 14. The exhaust pipe 15 is connected to the outside of the outer shell 2, and the gas floating in the oil is discharged to the outside of the online monitoring instrument body 1 through the exhaust pipe 15.

[0031] In actual use, when air bubbles are generated in the oil in the return pipe 9, power is supplied to the resistance heater 11. Since the resistance heater 11 is fixed inside the first curved tube 8, it heats the oil when it enters from the return port 10. The first curved tube 8 is U-shaped, which greatly increases the residence time of the oil inside, allowing it to be heated to a sufficient boiling temperature. Boiling causes the air bubbles to rise. When the high-temperature oil flows into the exhaust chamber 7, the increased pressure due to the rising temperature causes the pressure difference to open the check valve in the exhaust pipe 15, allowing the rising gas in the oil to pass through the exhaust pipe. 15 is discharged to the outside of the main body 1 of the online monitoring instrument. After passing through the exhaust chamber 7, the high-temperature oil flows into the second curved tube 13. Since the second curved tube 13 is fixed inside the condenser tube 5, the low-temperature refrigerant inside the condenser tube 5 will cool down the high-temperature oil in the second curved tube 13. The second curved tube 13 is shaped like an array of 'U', which greatly increases the residence time of the oil inside the second curved tube 13. Together with the fan blade 12, the high-temperature oil is cooled down to room temperature and enters the oil storage tank through the oil storage port 6, so that the oil in the oil storage tank is free of air bubbles, thus not affecting the next monitoring data. At the same time, the radiator 4 will cool down the refrigerant in the condenser tube 5 to realize the recycling of the refrigerant.
