Description

Technical Field

[0001] The utility model relates to the technical field of natural gas sampling, in particular to a metering natural gas sampling device. Background Technique

[0002] Natural gas sampling plays a crucial role in the entire energy industry. By using a natural gas sampler, gas samples can be safely and accurately extracted from natural gas pipelines, gas storage tanks, or wellheads. These samples can truly reflect the properties and components of the measured gas, helping to ensure the quality and safety of natural gas. For this reason, a metering natural gas sampling device is proposed.

[0003] The existing Chinese utility model patent with the reference publication number: CN213903022U discloses a liquefied natural gas sampling device, belonging to the technical field of liquefied natural gas. In this technical solution, it includes a sampler body. A top cover is arranged at the top of the sampler body. A hydraulic telescopic rod is fixedly connected to the inner top of the sampler body. The bottom end of the telescopic rod of the hydraulic telescopic rod is fixedly connected to a sampling drill. The output shaft of the sampling drill is fixedly connected to a sampling storage tube through a mounting member. A sampling drill bit is arranged at the bottom end of the sampling storage tube. A side rail is arranged outside the sampler body, and a moving slider is installed outside the side rail. The utility model relates to the technical field of liquefied natural gas. This liquefied natural gas sampling device achieves the purpose of convenient placement of the overall device, and is convenient for recycling and storage after use. The adjustable external frame is convenient for adapting to a variety of different positions. The sampling speed is fast, and the preservation is rapid. The dual preservation settings of high pressure and low temperature ensure that the liquefied natural gas inside the sampler body can be effectively preserved after recovery.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that since the internal components of natural gas are complex during sampling, it cannot be guaranteed that the natural gas is completely sampled by the sampling device, resulting in a small amount of natural gas sampling dose. And after sampling, the natural gas cannot be completely discharged from the inside of the equipment, resulting in gas mixing, which is not conducive to the accurate detection of the internal components of natural gas. The existence of these problems affects the use of the device. Content of the Utility Model

The gas inside the sampling device 1 is pressed, and natural gas will be continuously discharged from the upper transmission pipe 24, thereby exhausting the gas inside the sampling device 1.

[0029] The natural gas sampling and monitoring mechanism includes: a gas detector 3 connected to the left side of the sampling device 1. A connecting column 31 is fixedly connected to the bottom of the gas detector 3. A connecting pipe 32 is installed below the inside of the sampling device 1. The bottom of the connecting pipe 32 is connected to a pressing ring 34. A driver 35 is installed on the left side of the pressing ring 34, and a detection device 33 is installed on the right side of the pressing ring 34; there is an interconnected structure between the connecting column 31 and the sampling device 1. The connecting pipe 32 is located in the middle of the inside of the sampling device 1. The pressing ring 34 is located above the connecting screw 42. The bottom of the sampling device 1 is connected to an equipment bottom ring 36, and a round hole is provided at the midpoint of the equipment bottom ring 36.

[0030] Specifically, a gas detector 3 is installed on the side of the sampling device 1. The gas detector 3 is interconnected with the sampling device 1 through a connecting column 31, which facilitates the gas detector 3 to detect the gas inside the sampling device 1. Also, according to the installation of a connecting pipe 32 inside the sampling device 1, the connecting pipe 32 transports the natural gas device inside the extraction device 4 into the sampling device 1. And a pressing ring 34 is installed at the bottom of the connecting pipe 32. The pressing ring 34 is controlled by the driver 35 to press downwards, closing the transportation of natural gas inside the sampling device 1 and at the same time sealing the original natural gas inside the sampling device 1 to prevent gas leakage.

[0031] The midpoint of the sampling device 1 is connected to an extraction device 4. A content detector 41 is installed above the middle of the extraction device 4.

The gas detector 3 is interconnected with the sampling device 1 through a connecting column 31, facilitating the gas detector 3 to detect the content of the gas inside the sampling device 1. When the sampling device 1 is filled with natural gas, the pressing ring 34 is pressed downward by means of the driver 35 to close the round hole at the bottom of the sampling device 1, preventing the natural gas from continuing to enter and sealing and storing the natural gas already installed in the sampling device 1. When the natural gas inside the sampling device 1 needs to be discharged, the pressing device 2 above the sampling device 1 can be pressed downward. The operation of the pressing device 2 drives the pneumatic rod 21 and the pressing plate 22 to move downward reciprocally. The gas inside the sampling device 1 is pressed, and the natural gas will continuously be discharged from the upper transfer pipe 24, thereby discharging all the gas inside the sampling device 1 and avoiding subsequent gas mixing.
