According to the water vapor cooling process, the cooling requirement for the pre-cooling device is lower than that of the constant temperature cooling device. Based on this, in the utility model, the flow direction of the cooling water is opposite to the flow direction of the water vapor, improving the cooling effect on the water vapor and the cooling speed".

[0004] However, the water vapor sampling device in the above-mentioned published literature mainly considers that the flow direction of the cooling water is opposite to the flow direction of the water vapor, improving the cooling effect on the water vapor and the cooling speed, and is not convenient for fixing sampling pipes of different sizes and does not require manual holding of the sample.

[0005] In view of this, it is necessary to study a positioning mechanism, which can then fix sampling pipes of different sizes and does not require manual holding of the sample. Content of the Utility Model

[0006] The purpose of the utility model is to provide a water vapor sampling device to solve the technical problem of enabling the water vapor sampling device to have a sampling pipe positioning function as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A water vapor sampling device, comprising: a sampling frame, a sampling pump is installed on the inner wall of the sampling frame, a pipeline is installed at the water inlet end of the sampling pump, a flange is installed on the outer wall of the pipeline, and a positioning mechanism is provided on the inner wall of the sampling frame. The positioning mechanism is used to fix sampling tubes of different sizes, eliminating the need for manual holding of the sampling;

[0010] Preferably, a cooling and filtering mechanism is provided on the inner wall of the sampling frame. The cooling and filtering mechanism is used to cool the water vapor sample to avoid damaging the sampling device, and at the same time filter the water vapor sample to improve the accuracy of the test data.

[0011] Preferably, the cooling and filtering mechanism includes a filter screen disposed on the inner wall of the flange.

[0012] Preferably, a locking groove is provided on the outer wall of the filter screen. A locking rod is installed on the outer wall of the flange, and one end of the locking rod extends into the interior of the locking groove.

At the same time, according to the height of the sampling tube, the height of the positioning plate driven by the adaptor pole is adjusted, so that the spacing between the positioning plate and the mounting plate can place the sampling tube. Then, the pole is adjusted to drive the sampling tube to move, so that the sampling tube moves to the bottom of the water outlet of the sampling pump to receive the sample, thereby eliminating the need for manual frequent hand-held sampling tubes, reducing the waste of manpower.

[0017] 2. The utility model is equipped with a cooling and filtering mechanism to cool down the water vapor sample to avoid damaging the sampling device, and at the same time filter the water vapor sample to improve the accuracy of the test digital. When sampling the water vapor specimen, the temperature of the water vapor sample is too high, and the impurities in the sample may cause large errors in the detection, so it is necessary to improve this. First, the filter is installed in the flange, and the locking rod is fixed to the locking groove to fix the position of the filter.

Then, the first solenoid valve is closed, and the second solenoid valve is opened to transport the cooled water vapor. At the same time, the coolant in the cooling water bag can be replaced. The coolant in the cooling water bag can be discharged and replaced by twisting the ball valve, so as to process the temperature and impurities of the water vapor to avoid affecting the sampling and test results.

[0027] Please refer to Figure 1 and Figure 2A water vapor sampling device comprises: a sampling frame 1, a sampling pump 5 is installed on the inner wall of the sampling frame 1, a pipe 6 is installed on the water inlet end of the sampling pump 5, a flange 7 is installed on the outer wall of the pipe 6, a control end 2 is installed on the outer wall of the sampling frame 1, a sampling door plate 3 is installed on the outer wall of the sampling frame 1, and a sampling placement slot 4 is provided on the outer wall of the sampling frame 1, which is connected to an external device to be sampled through the flange 7.

[0028] See also Figure 2 , Figure 3 and Figure 4 The inner wall of the sampling frame 1 is provided with a positioning mechanism, which is used to fix sampling tubes of different sizes, without manual hand-held sampling, and the positioning mechanism includes an adjusting pole 8, which is arranged on the inner wall of the sampling frame 1, and an adjusting pole 8 is installed with a mounting plate 9 at the output end of the adjusting pole 8, and an adapting pole 10 is installed with an outer wall of the mounting plate 9, and a disassembly screw groove 11 is provided on the outer wall of the disassembly screw groove 11, and a disassembly stud 12 is installed on the inner wall of the disassembly stud 12, and a positioning plate 13 is installed on the outer wall of the disassembly stud 12, and a locking groove 14 is provided on the inner wall of the positioning plate 13, and a first protective plate layer 15 is installed on the inner wall of the locking groove 14, and an adhesive layer 16 is installed on the outer wall of the first protective plate layer 15, and a second protective plate layer 17 is installed on the outer wall of the adhesive layer 16. When sampling steam, it is often necessary to manually hold the sampling tube, which leads to a great waste of human resources. Therefore, it is necessary to improve this. First, the number of protective plate layers is selected according to the diameter of the sampling tube. If it needs to be increased, the second protective plate layer 17 is adhered to the first protective plate layer 15 through the adhesive layer 16, so that the sampling tube can be stuck in the fixing groove 14. At the same time, according to the height of the sampling tube, the height of the positioning plate 13 is adjusted by the adapter pole 10, so that the spacing between the positioning plate 13 and the mounting plate 9 can place the sampling tube. Then, the pole 8 is adjusted to drive the sampling tube to move, so that the sampling tube moves to the bottom of the water outlet of the sampling pump 5 to receive the sample, thereby eliminating the need for manual frequent hand-held sampling tubes and reducing waste of manpower.

[0029] See also Figure 2 and Figure 5, a cooling and filtering mechanism is provided on the inner wall of the sampling frame 1. The cooling and filtering mechanism is used to cool the water vapor sample to avoid damaging the sampling device, and at the same time filter the water vapor sample to improve the accuracy of the test data. The cooling and filtering mechanism includes a filter net 18. The filter net 18 is arranged on the inner wall of the flange 7. A locking groove 19 is provided on the outer wall of the filter net 18. A locking rod 20 is installed on the outer wall of the flange 7, and one end of the locking rod 20 extends into the inside of the locking groove 19. A coolant frame 21 is installed on the inner wall of the sampling frame 1. A liquid adding groove 22 is provided at the top of the sampling frame 1, and one end of the liquid adding groove 22 extends into the inside of the coolant frame 21.

A spherical valve 27 is installed on the inner wall of the drain pipe 26. A first solenoid valve 28 and a second solenoid valve 29 are respectively installed on the inner wall of the pipeline 6. Since during the sampling of the water vapor specimen, due to the too high temperature of the water vapor sample and the impurities in the sample may cause large errors in the detection, it is necessary to make improvements. First, install the filter net 18 in the flange 7, fix the locking rod 20 into the locking groove 19 to fix the position of the filter net 18. Then add the coolant into the coolant frame 21 through the liquid adding groove 22. Subsequently, the water pump 23 works to transport the coolant to the cooling water bag 25. Then the cooling water bag 25 contacts the pipeline 6. Subsequently, the second solenoid valve 29 is closed, so as to cool the water vapor in the pipeline 6 in the cooling water bag 25. Then the first solenoid valve 28 is closed and the second solenoid valve 29 is opened to transport the cooled water vapor. At the same time, the coolant in the cooling water bag 25 can be replaced. By turning the spherical valve 27, the coolant in the cooling water bag 25 can be drained and replaced, thereby treating the temperature and impurities of the water vapor to avoid affecting the sampling and test results.

[0030] The working principle is to connect the sampling equipment to the outside world through the flange 7, and then the sampling pump 5 works to extract water vapor, and then the sampling door panel 3 is opened, and the extracted water vapor is received by using a manual hand-held sampling tube, and then the sampling tube is placed in the sampling placement slot 4. In the existing process of sampling water vapor, it is often necessary to manually hold the sampling tube, which leads to a great waste of human resources, so it is necessary to improve this. First, the number of protective plate layers is selected according to the diameter of the sampling tube. If it needs to be increased, the second protective plate layer 17 is adhered to the first protective plate layer 15 through the adhesive layer 16, so that the sampling tube can be stuck in the fixing groove 14. At the same time, according to the height of the sampling tube, the height of the positioning plate 13 is adjusted by the operation of the adapter pole 10, so that the spacing between the positioning plate 13 and the mounting plate 9 can place the sampling tube, and then the pole 8 is adjusted to drive the sampling tube to move, so that the sampling tube moves to the bottom of the water outlet of the sampling pump 5 to receive the sample, thereby eliminating the need for frequent manual operation. A handheld sampling tube is used to reduce the waste of manpower. When sampling water vapor specimens, the temperature of the water vapor sample is too high, and impurities in the sample may cause large errors in the detection. Therefore, it is necessary to improve this. First, the filter 18 is installed in the flange 7, and the locking rod 20 is fixed to the locking groove 19 to fix the position of the filter 18. Then, the coolant is added to the coolant frame 21 through the liquid adding groove 22. Then, the water pump 23 works to transport the coolant to the cooling water bag 25, and the cooling water bag 25 contacts the pipeline 6. Then, the second solenoid valve 29 is closed, and the water vapor in the pipeline 6 in the cooling water bag 25 is cooled. Then, the first solenoid valve 28 is closed, and the second solenoid valve 29 is opened to transport the cooled water vapor. At the same time, the coolant in the cooling water bag 25 can be replaced. The coolant in the cooling water bag 25 can be discharged and replaced by twisting the ball valve 27, so as to process the temperature and impurities of the water vapor to avoid affecting the sampling and test results.
