Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4 The utility model provides a technical solution: an automatic exhaust device applied to a closed pipeline, comprising an air intake pipe 1, a sealing groove 4 is provided on the upper end surface of the air intake pipe 1, a sealing gasket 5 is fitted and connected to the middle of the sealing groove 4, a shell 6 is connected above the air intake pipe 1, a sealing plate 7 is fixedly connected to the outer surface of the shell 6, and the lower end surface of the sealing plate 7 is fitted and connected to the upper end surface of the sealing gasket 5;

A connecting hole 18 is provided on the outer surface of the wind shield 17, and the fixing hole 16 is communicated with the connecting hole 18.
[0027] A sealing gasket 5 is added at the connection between the intake pipe 1 and the shell 6. When the two are fastened, the sealing gasket 5 can fill the gap at the connection between the intake pipe 1 and the shell 6, prevent gas or liquid from flowing out, prevent leakage, and effectively ensure the stability and sealing effect of the device; a wind shield 17 is arranged at the front end of the exhaust pipe 10, and the wind shield 17 is fixedly connected to one side of the exhaust pipe 10 by bolts. The wind shield 17 is hemispherical and can effectively reduce the interference of external wind on the exhaust flow, ensure smooth exhaust, thereby improving exhaust efficiency, and can effectively avoid the influence of strong wind on exhaust, thereby improving the use effect of the wind shield 17.
[0028] Furthermore, an air inlet 2 is provided in the middle of the air inlet pipe 1, and an internal thread groove 3 is provided on the inner wall of the air inlet pipe 1. When the solar collector is filled with water, due to changes in temperature and pressure, the gas in the water will gather in the shell 6 along the air inlet 2, and then through the threaded connection, the reliability of the connection between the shell 6 and the air inlet pipe 1 can be ensured, and the installation and disassembly are simple, thereby improving work efficiency.
[0029] Furthermore, a first external thread coil 8 is provided on the bottom outer surface of the shell 6, and the first external thread coil 8 is threadedly connected to the internal thread groove 3.

[0031] Furthermore, an exhaust port 11 is opened in the middle of the exhaust pipe 10. When the gas pressure in the middle of the shell 6 is greater than the pressure of the solar collector, the float 14 will fall and drive the lever 13 to move downward.

[0032] Furthermore, a sealing spring 12 is fixedly connected to one end of the exhaust pipe 10. When the gas pressure in the middle of the shell 6 is greater than the pressure of the solar collector, the float 14 will fall and drive the lever 13 to move downward.

Such a cyclic operation can ensure that the gas in the solar collector is discharged in time, effectively avoid problems such as gas blockage, and improve the operating efficiency and safety of the solar water heating system.
[0033] Furthermore, one end of the sealing spring 12 is fixedly connected to a lever 13. When the gas pressure in the middle of the shell 6 is greater than the pressure of the solar collector, the float 14 will fall and drive the lever 13 to move downward.
[0034] Furthermore, the end of the lever 13 is fixedly connected to the float 14, and the float 14 is made of stainless steel, so that it has high temperature resistance and corrosion resistance, and can ensure the safety of personnel and the stability of equipment when exhausting in the solar collector.
[0035] Working principle: For this type of automatic exhaust device used in closed pipelines, when the solar collector is filled with water, due to changes in temperature and pressure, the gas in the water will gather in the shell 6 along the air inlet 2. When the gas pressure in the middle of the shell 6 is greater than the pressure of the solar collector, the float 14 will fall and drive the lever 13 to move downward. The lever 13 pulls the sealing spring 12 to deform, causing the gas to flow out from the gap of the sealing spring 12 and be discharged through the exhaust port 11. Such a cycle operation can ensure that the gas in the solar collector is discharged in time, effectively avoid problems such as gas blockage, and improve the operating efficiency and safety of the solar water heating system. A wind shield 17 is set at the front end of the exhaust pipe 10. The wind shield 17 is fixedly connected to one side of the exhaust pipe 10 by bolts. The wind shield 17 is hemispherical, which can effectively reduce the interference of external wind on the exhaust flow, ensure smooth exhaust, thereby improving the exhaust efficiency, and can effectively avoid the influence of strong wind on the exhaust, thereby improving the use effect of the wind shield 17.
