[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-5 The gas circuit system of the analysis and detection laboratory includes a gas tank 1 and a mounting plate 3. The gas outlet end of the gas tank 1 is connected to an inner tube 202, and a part of the inner tube 202 is mounted on the mounting plate 3. The gas circuit system also includes: an outer tube 201, which is fixedly connected to the outside of the inner tube 202, and a closed cavity is provided between the outer tube 201 and the inner tube 202; a water tank 4, which is mounted on the mounting plate 3, and a water pump 401 is connected to the water tank 4, and a water outlet pipe 4021 is connected to the liquid outlet end of the water pump 401, and the water outlet Tube 4021 is communicated with the cavity and is used to inject water into the cavity; a return pipe 4022 is connected to the water tank 4, and is used to return the water in the cavity to the water tank 4; a heating wire 5 is arranged in the water tank 4, and is used to heat the water in the water tank 4. Multiple sets of detection meters 203 are fixedly connected to the outer tube 201, and the detection meters 203 are used to detect various values ​​inside the inner tube 202. The liquid inlet end of the return pipe 4022 is far away from the liquid outlet end of the outlet pipe 4021.

[0028] The cavity is arranged between the inner tube 202 and the outer tube 201 , and both ends of the outer tube 201 are sealed to form a closed cavity.

[0029] Before use, the water in the water tank 4 can be heated to a suitable range, generally 23°C, by the heating wire 5, and then the heated water is transferred to the cavity by the water pump 401, and the original cold water in the cavity will be gradually replaced by hot water, so that the temperature of the inner tube 202 can be controlled between 21°C and 25°C.

[0030] Once the temperature is appropriate, the gas inside the gas circuit can be used, which is convenient for laboratory experiments.

[0031] Embodiment 2:

[0032] Reference Figure 1-5 The gas circuit system of the analysis and detection laboratory is basically the same as that of Example 1, and furthermore: a sealing cover 403 is rotatably connected to the water tank 4, and a pressure gauge 6 is connected to the water tank 4, and the pressure gauge 6 is used to detect the pressure in the water tank 4.

[0033] When the inner tube 202 is used for a long time, there is a risk of leakage. At this time, the leaked gas will enter the cavity, thereby squeezing the water and increasing the pressure in the water tank 4. At this time, the pressure change can be detected through the pressure gauge 6, and then it can be known that a leakage has occurred. At this time, it is necessary to close the gas tank 1 and perform a leak detection.

[0034] The utility model can effectively control the temperature outside the inner tube 202 through the setting of the cavity, so that the temperature can reach a suitable range, which is convenient for the use of gas line engineering. At the same time, the pressure value inside the cavity can be detected to facilitate knowing whether the inner tube 202 is leaking.

[0035] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
