Description

Technical Field

[0002] Flow rate sensors are widely used in gas, fuel cells, semiconductors, analytical instruments, petrochemicals, medical and other industries. They are sensors that can display cumulative flow, instantaneous flow, pressure and temperature. When the gas flow rate sensor is connected to a pipeline for monitoring, the nitrogen, helium, hydrogen and other gases transmitted by the pipeline will have pressure during the transmission process, which will generate impact force.

[0003] A gas flow rate sensor with the Chinese authorization announcement number CN217639143U is provided. A sealing buffer device is added between the gas flow rate sensor and the gas pipeline, and the gas pipeline and the flange are wrapped and sealed by a sealing component. Then, the pressure impact force generated by the gas during the transmission process drives the telescopic tube sleeve to move left and right, and then the inflation group inflates the airbag to inflate the airbag. After the airbag expands, the impact force of the buffer component on the flange caused by the impact force of the gas is reduced, so that the connection between the sealing buffer device and the flange will not be deformed, which is convenient for disassembly and replacement in the future.

[0004] There are still certain shortcomings in use. The sensor needs to be fixed on the surface of the pipe through a connecting column when in use. When the sensor needs to be replaced, it is not convenient to replace the sensor because it is fixed together, which reduces the practicality of the sensor when in use. At the same time, it is inconvenient to fix the sensor on the surface of pipes with different diameters, which will also reduce the scope of use of the sensor. Utility Model Content
