Description

Technical Field

[0001] The utility model relates to the technical field of natural gas sampling, in particular to a natural gas pressure-stabilizing sampling device. Background Art

[0002] Natural gas, the so-called clean energy, has entered thousands of households and improved people's quality of life. In order to better store natural gas, it is necessary to sample and test the natural gas in the natural gas storage tank.

[0003] For existing natural gas pressure-stabilizing sampling devices, reference can be made to the Chinese utility model patent with authorization publication number CN211856049U, which discloses a natural gas pressure-stabilizing sampling device. "Open the pressure-maintaining stop valve to build up pressure at one end of the sampling bottle, and this pressure is lower than the pressure in the natural gas reservoir. Once the pressure indicator at one end of the sampling bottle stabilizes and the pressure at that end remains stable, close the pressure-maintaining stop valve. Upon opening the sampling stop valve, natural gas from the natural gas reservoir enters the other end of the sampling bottle under the action of a higher pressure. Pressure has already been established at one end of the sampling bottle, and after entering the sampling bottle, the natural gas does not directly enter a very low-pressure environment from a high-pressure environment. Therefore, throttling and expansion will not occur, ensuring a stable pressure-sampling device for the natural gas. After the pressure indicator reaches stability again, the pressure-maintaining flow control valve at one end of the sampling bottle can be further opened. The pressure-maintaining flow control valve adjusts the airflow, allowing the natural gas at one end of the sampling bottle to be slowly released while the other end of the sampling bottle continues to slowly enter natural gas until the sampling bottle is filled with natural gas."

[0004] When the above-mentioned equipment is in use, the purpose of sampling is achieved by cooperating with the pressure-maintaining stop valve and the sampling bottle. However, when the above-mentioned device is sampling, the fixing structure of the sampling bottle is relatively simple and requires personnel to use tools to fix it, which reduces the practicality of the device. When the above-mentioned device is sampling, due to the influence of the ambient temperature, the sampling bottle cannot be temperature-controlled, which affects the stability of the natural gas. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a natural gas pressure-stabilizing sampling device, which has the advantages of facilitating the fixation of the sampling bottle, improving the practicality of the device, and being able to control the temperature of the sampling bottle, reducing the impact of the ambient temperature on the stability of the natural gas in the sampling bottle, thereby solving the problems raised in the above-mentioned background technology.

[0009] As a preferred technical solution of the present invention, the outer edge of the threaded rod is threadedly connected to the bottom of the mounting tube, and a square groove is provided on the outer surface of the connecting tube.

[0010] As an optimal technical solution of the present invention, the fixing device includes a rotating rod, the outer wall of the rotating rod is fixedly equipped with a gear ring, the inner wall of the gear ring is engaged with a third gear, and the top of the third gear is fixedly equipped with a clamping block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The natural gas pressure-stabilizing sampling device drives the gear ring to rotate by rotating the rotating rod. The third gear meshing with the inner wall of the gear ring causes the gear ring to rotate while driving the third gear to rotate. The clamping block fixedly assembled on the top of the third gear causes the clamping block to rotate under force, causing the clamping block to turn inward. The motor is provided to drive the first gear to rotate. The second gear meshing with the gear ring teeth causes the second gear to rotate under force, thereby driving the threaded rod to rotate, and then driving the mounting tube and the fixing device to move, thereby achieving the purpose of fixing the sampling bottle and improving the practicality of the device.

[0014] 2. The natural gas pressure-stabilizing sampling device is capable of refrigeration through the operation of a refrigerator. The refrigeration rod fixedly installed on the outer wall of the refrigerator can cool the inside of the shell, thereby achieving the purpose of cooling the sampling bottle, reducing the impact of the ambient temperature on the sampling bottle, maintaining the stability of natural gas during the sampling process, and improving the convenience of the device during sampling.
