[0021] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1-3, the high-temperature liquid sampling device of this utility model includes a sampling connector assembly and a sampling bottle assembly. The sampling connector assembly includes a connector body 1, a threaded guide block 3, and a nut 4. See Figure 3 for details. The connector body 1 has a sampling port 16 and an exhaust port 17. The sampling port 16 is used to connect to a sampling system, which is directly connected to a process pipeline for real-time sampling. An opening 19 is provided on the opposite side of the sampling port 16, and the sampling port 16 and the exhaust port 17 communicate with the opening 19. An annular groove 18 is provided inside the opening 19, and a toothed graphite ring 2 is provided in the annular groove 18. A male thread that engages with the nut 4 is provided at the opening 19, and the nut 4 is threadedly connected to the opening 19 of the connector body 1. The threaded guide block 3 is disposed inside the nut 4, and a protrusion on the threaded guide block 3 abuts against the inner shoulder of the nut 4, thereby confining the threaded guide block 3 within the nut 4. After the nut 4 is tightened, the upper end of the threaded guide block 3 abuts against the toothed graphite ring 2, holding the toothed graphite ring 2 in place. In a preferred embodiment, the sampling connector assembly also includes a safety plug 5. The threaded guide block 3 has a female thread, and the safety plug 5 is threadedly connected inside the threaded guide block 3. The safety plug 5 is made of plastic, which prevents foreign objects from entering the threaded guide block 3 before sampling, ensuring the cleanliness of the sampling connector assembly. After sampling, it prevents residual media from dripping and contaminating the environment. An open ring 6 can also be provided on the safety plug 5, which is fixed to the bottom of the safety plug 5 with screws. The open ring 6 can be suspended in a fixed position after the safety plug 5 is removed, avoiding random placement.

[0023] The sampling bottle assembly includes a sampling bottle 12 (see Figure 2). The sampling bottle 12 is a stainless steel bottle container with an open end and a male thread at the open end. During sampling, the sampling bottle 12 is threadedly connected to the threaded guide block 3, and the sampling port 16 and the vent port 17 are in communication with the sampling bottle 12. At this time, the toothed graphite ring 2 forms a seal between the sampling bottle 12 and the connector body 1. The sampling bottle 12 is provided with a heat insulation layer, which includes heat insulation rock wool 13 and heat insulation sleeve 14. The heat insulation rock wool 13 is provided in the inner layer, and the heat insulation sleeve 14 is provided in the outer layer. The heat insulation layer can prevent burns to the operator when sampling high-temperature liquid media. Furthermore, a handle 15 can also be provided on the heat insulation layer to facilitate the handling and placement of the sampling bottle 12.

[0024] The sampling bottle assembly also includes a cap 7, which is also made of stainless steel. Before sampling, the cap 7 is screwed onto the opening of the sampling bottle 12 to prevent foreign objects from entering the sampling bottle 12. After sampling, the cap 7 prevents the hot liquid medium from splashing out. A toothed graphite gasket 8 is also provided inside the cap 7, which is fixed inside the cap 7 by screws 11, flat washers 9, and spring washers 10. After the cap 7 is tightened onto the sampling bottle 12, the mouth of the sampling bottle 12 is pressed tightly against the toothed graphite gasket 8, forming a seal between the sampling bottle 12 and the cap 7.

[0025] The working principle of this utility model is as follows: The sampling connector assembly is installed on the sampling system. During sampling, the safety plug 5 is unscrewed, the bottle cap 7 on the sampling bottle assembly is removed, and the sampling bottle 12 is threaded onto the threaded guide block 3. The control valve of the sampling system is opened, and the high-temperature liquid medium in the process pipeline flows into the sampling port 16 of the connector body 1 through the sampling system and into the sampling bottle 12. The air in the sampling bottle 12 is discharged through the exhaust port 17. After a suitable amount of sample is obtained, the control valve of the sampling system is closed, the sampling bottle 12 is unscrewed, the safety plug 5 is screwed into the threaded guide block 3, and then the bottle cap 7 is tightened on the bottle mouth of the sampling bottle 12. The sampling bottle 12 can then be sent to the laboratory for analysis.
