Description

Technical Field

[0001] The utility model is applicable to the technical field of mechanical pressure gauges, and in particular relates to a pressure gauge movement. Background Art

[0002] Mechanical pressure gauges are instruments that use elastic elements as sensitive elements to measure and indicate pressures higher than the ambient pressure. They are widely used in almost all industrial processes and scientific research fields. They can be found everywhere in the fields of thermal pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and easy production.

[0003] However, the existing pressure gauge does not have an anti-vibration function. When the pressure gauge itself vibrates, the movement inside the dial will also vibrate. When the vibration occurs for a long time, the parts inside the movement are easily damaged and difficult to repair, which can easily lead to inaccurate measurements. In order to solve the above technical problems, we propose a new anti-vibration pressure gauge movement. Utility Model Content
