[0002] A gas pressure gauge is an instrument used to measure the pressure in a gas pipeline. It is commonly used to monitor the pressure of gas pipelines, gas appliances, and other equipment to ensure their normal operation. When gas enters the pressure gauge, it acts on the sensitive element, causing it to deform. This deformation is converted into the rotation of the pointer through a series of mechanical transmission mechanisms, thus displaying the current gas pressure on the dial.

[0003] Gas pressure gauges, as pressure monitoring devices for gas pipelines, play an important and widespread role in the laying of gas pipelines. However, during the installation and use of gas pipelines, some gas pressure gauges are difficult to install indoors, forcing them to be installed outdoors or in locations prone to impact.
