[0020] The following further describes the present application in detail with reference to the attached Figure 1 - attached Figure 3 drawings.

[0021] The embodiment of the present application discloses a toluene moisture inspection sampling device. Refer to Figures 1-3, A toluene moisture inspection sampling device, including the reaction kettle valve body 1. One end of the reaction kettle valve body 1 is fixed with a toluene inlet valve 2. One end of the toluene inlet valve 2 is fixed with a U-shaped glass tube 3. The outer wall of the U-shaped glass tube 3 is fixed with a water inlet pipe 4. The outer wall of the water inlet pipe 4 is fixed with a water inlet valve 5. A connecting pipe 6 is fixed on the water inlet valve 5. One end of the connecting pipe 6 can be connected to the tap water valve. During the experiment, first open the reaction kettle valve body 1 to discharge a small part of toluene, and then slowly open the water inlet valve 5. At this time, an interface may appear in the glass tube, which is formed by toluene and water. We need to observe this interface to judge whether there is moisture in the toluene. If there is no obvious interface in the U-shaped glass tube 3, it means that the water content in the toluene is relatively high; on the contrary, if there is an obvious interface in the U-shaped glass tube 3, it means that the water content in the toluene is relatively low. This step is the key to judging whether the toluene sample meets the requirements. After the observation is completed, the tap water valve needs to be closed, and the reaction kettle valve body 1 is opened to continue discharging toluene. This process needs to be repeated many times until there is an interface of water and toluene in the U-shaped glass tube 3, so as to ensure the accuracy of the moisture inspection result of the toluene sample. During this process, the operator needs to closely monitor the interface of water and toluene in the U-shaped glass tube 3 to accurately judge the water content of the toluene. After multiple tests, when there is an interface of water and toluene in the U-shaped glass tube 3, it means that the moisture inspection of the toluene has been completed, and the toluene meets the requirements and can be put into use. 1. It can reduce the risk during the toluene moisture inspection sampling process, improve the safety factor, reduce the possibility of contacting toxic and harmful gases, and enhance the occupational health protection of the operator.

[0022] After the technical improvement of the toluene moisture detection sampling device, to check whether toluene contains water, it is not necessary to discharge toluene. It can be directly viewed in the U-shaped glass tube. The unqualified ones are directly discharged to the toluene receiving tank and centrally processed after reaching a certain amount. There is no escape of harmful gases, nor the formation of an explosive mixture with the outside air, which greatly reduces the risk during the toluene moisture detection sampling process.

[0023] Refer to Figure 2 , One end of the U-shaped glass tube 3 is fixed with a tetrafluoro soft connection 10. The U-shaped glass tube 3 is fixed on the toluene inlet valve 2 through the tetrafluoro soft connection 10. The tetrafluoro soft connection 10 can protect the U-shaped glass tube 3 from being damaged by the pulling force of other pipes.

[0024] Refer to Figure 1 , It also includes a protective frame 8. An avoidance groove 9 is opened on the water inlet valve 5 for the toluene inlet valve 2, the U-shaped glass tube 3 and the water inlet pipe 4 to pass through. The protective frame 8 is composed of multiple round rods connected to each other. It can prevent the valve handle from hitting the U-shaped glass tube 3 and make it not easy to be damaged.

[0025] Refer to Figure 2, the U-shaped glass tube 3 and the water inlet pipe 4 are integrally manufactured; facilitating production and manufacturing.

[0026] The implementation principle of a toluene moisture inspection sampling device according to an embodiment of the present application is as follows: One end of the connecting pipe 6 can be connected to a tap water valve;

[0027] During the experiment, first open the reaction kettle valve body 1 to discharge a small part of toluene, and then slowly open the water inlet valve 5. At this time, an interface may appear in the glass tube, which is formed by toluene and water. We need to observe this interface to determine whether there is moisture in the toluene. If there is no obvious interface in the U-shaped glass tube 3, it indicates that the water content in the toluene is relatively high; on the contrary, if there is an obvious interface in the U-shaped glass tube 3, it indicates that the moisture content in the toluene is relatively low. This step is the key to determining whether the toluene sample meets the requirements;

[0028] After the observation is completed, the tap water valve needs to be closed, and the reaction kettle valve body 1 is opened to continue discharging toluene. This process needs to be repeated multiple times until there is an interface between water and toluene in the U-shaped glass tube 3, so as to ensure the accuracy of the toluene sample moisture inspection result. During this process, the operator needs to closely monitor the interface between water and toluene in the U-shaped glass tube 3 to accurately judge the moisture content of toluene;

[0029] After multiple tests, when there is an interface between water and toluene in the U-shaped glass tube 3, it indicates that the toluene moisture inspection work has been completed, and the toluene meets the requirements and can be put into use, which can reduce the risk during the toluene moisture inspection sampling process, improve the safety factor, reduce the possibility of contacting toxic and harmful gases, and enhance the occupational health protection for the operator;

[0030] After the technical improvement of the toluene moisture detection sampling device, to check whether toluene contains water, there is no need to discharge toluene. It can be directly viewed in the U-shaped glass tube. The unqualified ones are directly discharged to the toluene receiving tank and centrally processed after reaching a certain amount. There is no escape of harmful gases, nor the formation of an explosive mixture with the outside air, greatly reducing the risk during the toluene moisture detection sampling process.
