Description

Technical Field

[0001] The utility model relates to the technical field of natural gas samplers, in particular to a natural gas storage tank sampler. Background Technique

[0002] Natural gas can be said to be one of the indispensable energy sources in people's daily life nowadays. Moreover, as the proportion of natural gas in energy consumption continues to increase, the demand for natural gas also continues to innovate. At present, the quality inspection of natural gas separation products uses closed sampling steel cylinders for sampling. Only natural gas that has passed sampling and quality inspection can be used. In this process, a natural gas storage tank sampler will be used. However, the existing natural gas storage tank samplers still have some disadvantages. For example, the portability is insufficient. Most general natural gas samplers are large in size and complex in structure, which makes them inconvenient to carry and operate. And the use effect of the generally recommended samplers is not good, and there is often a phenomenon of leaking a large amount of natural gas. Therefore, we propose a natural gas storage tank sampler. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1:

[0018] Please refer to Figure 1-2 Figure 1-2 , the present utility model provides a technical solution: a natural gas storage tank sampler, which refers to a device for extracting samples from a natural gas tank, including a sampler main body 1. The sampler main body 1 is made of a transparent material. A connector 2 is connected to the left side of the sampler main body 1. A sampling pipe 3 is connected to the left side of the connector 2. A flange interface 4 is provided at one end of the sampling pipe 3 away from the connector 2. One end of the sampling pipe 3 away from the connector 2 can be connected to the natural gas tank through the flange interface 4. The inner cavity of the sampler main body 1 is set as an air extraction chamber 5. A piston block 6 is provided on the left side of the inner cavity of the air extraction chamber 5. A connecting rod 7 is provided in the middle of the right side of the piston block 6. The right side of the connecting rod 7 penetrates and extends to the outside of the right side of the sampler main body 1. A limiting block 8 is provided on the right side of the connecting rod 7. Initially, the piston block 6 is located on the left side of the inner cavity of the air extraction chamber 5. Then, by pulling the connecting rod 7, the piston block 6 can be moved to the right side of the inner cavity of the air extraction chamber 5. In this way, natural gas can be extracted from the natural gas tank through the sampling pipe 3. A connector one 9 is provided on the top left side of the sampler main body 1. An air outlet pipe 10 is connected to the top of the connector one 9. A three-way joint 11 is provided on the top of the air outlet pipe 10. The left and right sides of the three-way joint 11 are respectively connected with a first sampling conduit 12 and a second sampling conduit 13. Sampling tank connectors 14 are provided at one ends of the first sampling conduit 12 and the second sampling conduit 13 away from the three-way joint 11. The first sampling conduit 12 and the second sampling conduit 13 can both be connected to a sampling tank through the sampling tank connectors 14. The natural gas extracted by the air extraction chamber 5 will pass through the air outlet pipe 10 and then be split by the three-way joint 11 into the first sampling conduit 12 and the second sampling conduit 13 and finally enter the connected sampling tank. In this way, the sampling process of natural gas can be completed.

[0019] Among them, preferably, control valves 15 are provided at one ends of the first sampling conduit 12 and the second sampling conduit 13 close to the three-way joint 11. The provided control valves 15 can prevent the phenomenon of backflow in the connected sampling tank. At the same time, according to the usage requirements, it is possible to select whether to extract one bottle of natural gas sample or multiple bottles of natural gas samples. The first sampling conduit 12 and the second sampling conduit 13 are both made of flexible material tubes.

[0020] Preferably, the sampler main body 1 is set as a cylinder. A scale line is provided on the front end face of the sampler main body 1. The provided scale line can facilitate the staff to observe the moving distance of the piston block 6 in the air extraction chamber 5. A handle 16 is provided at the bottom of the sampler main body 1. The provided handle 16 can make it easier and more labor-saving for the staff to pick up the whole sampler.

[0021] Preferably, the outlet pipe 10 is set as a rigid material pipe, and the included angle between the outlet pipe 10 and the sampler main body 1 is set to ninety degrees. This setting avoids the phenomenon that the outlet pipe 10 is bent during use, thereby preventing the outlet pipe 10 from discharging natural gas normally.

[0022] Embodiment 2:

[0023] Refer to Figure 1-2 , the difference between this embodiment and the first embodiment is that the connecting rod 7 is set as a cylindrical shape, a flexible rubber layer is sleeved on the outer wall of the connecting rod 7, and an adhesive layer is provided between the inner wall of the flexible rubber layer and the outer wall of the connecting rod 7. This setting can increase the sealing performance at the connection between the connecting rod 7 and the sampler main body 1; the length of the connecting rod 7 from left to right is greater than the length of the sampler main body 1 from left to right. This setting can increase the moving range of the piston block 6 moving left and right in the air extraction chamber 5. The connecting rod 7 and the limiting block 8 are of an integrally formed structure. This setting can increase the structural stability between the connecting rod 7 and the limiting block 8.

[0024] The electrical appliances mentioned in this article are all connected to an external power source through wires.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
