Technical Field

[0001] The utility model relates to the technical field of gas transportation, in particular to a pipeline pressure converter for a gas transportation system. Background Art

[0002] A pipeline pressure converter is a device used to measure and convert the gas pressure in a pipeline. It is commonly used in gas delivery systems to monitor the pressure in the pipeline and convert it into an electrical signal or other form of output signal for monitoring, control or recording. Usually, a device called a pressure sensor is used to measure the pressure of the gas in the pipeline and convert it into a corresponding electrical signal. The converter then processes and converts these signals to make them suitable for connection to a control system, display, recorder or other equipment for further processing or monitoring. The pressure sensor is usually set in a flange so that the pressure of the gas in the pipeline can be detected during transportation.

[0003] However, since the pressure sensor is arranged inside the existing pipeline pressure converter, solid particles in the gas may easily damage the pressure sensor during the gas pressure detection process, causing damage to the pressure sensor and affecting its use. In view of this, we propose a pipeline pressure converter for a gas transmission system. Utility Model Content
