Description

Technical Field

[0001] This utility model relates to the technical field of natural gas sampling devices, specifically a natural gas sampling device. Background Technology

[0002] As the proportion of natural gas in national energy consumption continues to increase, the demand for natural gas is also growing. In the oil and gas industry, discovering more natural gas is a major problem faced by explorers. To solve this problem, it is necessary to study the genesis and accumulation of natural gas, and to sample natural gas to meet the needs of research. Natural gas is transported through natural gas pipelines, and sampling devices are needed when studying the gas in the pipelines.

[0003] Most natural gas sampling devices are of fixed size, which takes up a lot of space when transporting empty tanks and is very inconvenient to use. After the sampling is completed, the natural gas remaining in the pipeline is usually wasted and leaked into the air after the valve of the sampling device is closed, which poses a risk of small explosion. Therefore, a natural gas sampling device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas sampling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A natural gas sampling device includes a first tank and a second tank. A first fixing ring is fixedly connected to the outer side of the first tank. A telescopic tube is fixedly connected to the left side of the first tank. The end of the telescopic tube away from the first tank is fixedly connected to the second tank. A second fixing ring is fixedly connected to the outer side of the second tank. A fixing shell is fixedly connected to the left side of the first fixing ring. Anti-slip protrusions are fixedly connected to the outer side of the fixing shell. A telescopic rod located inside the fixing shell is fixedly connected to the right side of the second fixing ring. A fixing bolt is spirally connected to the fixing shell and the telescopic rod. A pressure gauge located to the left of the second fixing ring is fixedly connected to the top of the second tank.

[0007] Preferably, a connecting pipe is fixedly connected to the left side of the second tank body. The end of the connecting pipe away from the second tank body is connected to a first valve. The end of the first valve away from the connecting pipe is connected to a flexible hose. The end of the flexible hose away from the first valve is connected to a second valve. The side of the second valve away from the flexible hose is connected to a connector.

[0008] Preferably, there are several anti-slip protrusions, which are evenly distributed on the surface of the fixed shell.

[0009] Preferably, the fixed shell, telescopic rod, and fixing bolt are a set, and there are two sets of the fixed shell, telescopic rod, and fixing bolt, which are symmetrically arranged between the first fixing ring and the second fixing ring.

[0010] Preferably, the extended length of the telescopic tube is less than the combined length of the fixed shell and the telescopic rod, and the length of the fixed shell matches the length of the telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, through the components such as a first tank body, a first fixing ring, a telescopic tube, a fixing shell, anti-slip protrusions, a second fixing ring, a second tank body, a telescopic rod, and a fixing bolt, after the connector is connected to the target pipeline, rotating the fixing bolt allows it to be removed from inside the fixing shell and the telescopic rod. Without the fixing bolt's fixation, as natural gas is continuously poured in, the telescopic tube, which is in a contracted state, unfolds under the pressure of the natural gas to facilitate natural gas sampling. The fixing shell and the telescopic rod provide support for the extension of the telescopic tube, preventing the telescopic tube and the first tank body from swinging and causing injury to personnel. When not in use, directly pressing the first and second tank bodies allows the first and second tank bodies to open. The components approach each other, and the telescopic tube is folded under the guidance of the fixed shell and telescopic rod. After folding, it is reconnected to the fixed shell and telescopic rod through the fixing bolt, so that the length of the sampling device is fixed. The compressed sampling device can significantly reduce the space occupied by the tank. At the same time, compared with the all-metal tank, the overall weight is lighter and more convenient for transportation. The fixed shell and telescopic rod can also act as handles. The anti-slip protrusions on the outside of the fixed shell can provide greater friction when carrying the sampling device to prevent the sampling device from slipping. This solves the problem that most natural gas sampling devices are of fixed size, which take up a lot of space when transporting empty tanks and are very inconvenient to use.

[0013] 2. In this utility model, through the components such as the first valve, connecting pipe, hose, second valve, and connector, after sampling is completed, the first valve is closed first, and then the second valve is closed. The first valve can seal the natural gas inside the sampling device, and the second valve can seal the gas remaining in the hose between the second valve and the first valve. Through the dual-valve design, the leakage of residual gas in the hose can be effectively solved. This solves the problem that in existing sampling devices, after sampling is completed and the valve of the sampling device is closed, the residual natural gas in the pipeline is generally wasted and leaks into the air, which may cause a small explosion.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A natural gas sampling device includes a first tank 1 and a second tank 15. A first fixing ring 2 is fixedly connected to the outer side of the first tank 1. A telescopic pipe 3 is fixedly connected to the left side of the first tank 1. The end of the telescopic pipe 3 away from the first tank 1 is fixedly connected to the second tank 15. A second fixing ring 6 is fixedly connected to the outer side of the second tank 15. A fixing shell 4 is fixedly connected to the left side of the first fixing ring 2. Anti-slip protrusions 5 are fixedly connected to the outer side of the fixing shell 4. A telescopic rod 7 located inside the fixing shell 4 is fixedly connected to the right side of the second fixing ring 6. A fixing bolt 8 is spirally connected to the fixing shell 4 and the telescopic rod 7. A pressure gauge 9 located to the left of the second fixing ring 6 is fixedly connected to the top of the second tank 15.

[0023] A connecting pipe 10 is fixedly connected to the left side of the second tank 15. The end of the connecting pipe 10 away from the second tank 15 is connected to a first valve 11. The end of the first valve 11 away from the connecting pipe 10 is connected to a flexible hose 12. The end of the flexible hose 12 away from the first valve 11 is connected to a second valve 13. The side of the second valve 13 away from the flexible hose 12 is connected to a connector 14. There are several anti-slip protrusions 5, which are evenly distributed on the surface of the fixed shell 4. The multiple anti-slip protrusions 5 can increase the friction when holding the fixed shell 4 and prevent the sampling device from falling off. The fixed shell 4, the telescopic rod 7 and the fixing bolt 8 are a set. There are two sets of fixed shell 4, telescopic rod 7 and fixing bolt 8, which are symmetrically arranged between the first fixing ring 2 and the second fixing ring 6. The two sets of fixed shell 4, telescopic rod 7 and fixing bolt 8 can more stably guide the extension and retraction of the telescopic tube 3. The unfolded length of the telescopic tube 3 is less than the combined length of the fixed shell 4 and the telescopic rod 7. The length of the fixed shell 4 and the length of the telescopic rod 7 are matched.

[0024] Workflow: When a natural gas sampling device is needed, first connect connector 14 to the target pipeline. Then, rotate the fixing bolt 8 to remove it from the fixed housing 4 and telescopic rod 7. Without the fixing bolt 8, the telescopic tube 3 can extend. Both the first valve 11 and the second valve 13 are open. Natural gas enters the second tank 15, the telescopic tube 3, and the first tank 1 through connector 14, hose 12, and connecting pipe 10. As natural gas is continuously poured in, the telescopic tube 3, which is in a contracted state, unfolds under the pressure of the natural gas to facilitate natural gas sampling. The fixed housing 4 and telescopic rod 7 provide support for the extension of the telescopic tube 3, preventing the telescopic tube 3 and the first tank 1 from swaying due to gas inflow and causing injury to personnel. When not in use, directly press the first tank 1 and the second tank 15 to bring them closer together. Guided by the fixed housing 4 and the telescopic rod 7, the telescopic tube... 3. Fold the device. After folding, reconnect it to the fixed shell 4 and telescopic rod 7 via the fixing bolt 8 to fix the length of the sampling device. The compressed sampling device can significantly reduce the space occupied by the tank. At the same time, compared with the all-metal tank, the overall weight is lighter and more convenient for transportation. The fixed shell 4 and telescopic rod 7 can also act as handles. The anti-slip protrusions 5 on the outside of the fixed shell 4 can provide greater friction when carrying the sampling device to prevent it from slipping. The pressure gauge 9 can be used to observe the internal pressure of the sampling device to determine whether the sampling device is full. After sampling, first close the first valve 11, and then close the second valve 13. The first valve 11 can seal the natural gas in the sampling device. The second valve 13 can seal the gas remaining in the hose 12 between the second valve 13 and the first valve 11. The double valve design can effectively solve the problem of gas leakage in the hose 12.
