Description

Technical Field

[0001] The utility model belongs to the technical field of pressure gauges, and in particular relates to a device for improving the gas replacement efficiency of a pressure gauge. Background Art

[0002] The gas pressure gauge is a precision instrument that requires regular cleaning. Internal cleaning requires the addition of alcohol, but the inlet is extremely small, so it must be slowly added using a syringe for cleaning. After cleaning, the alcohol must be shaken out. The traditional method is to manually shake the gauge out, which is laborious and time-consuming, prone to residue and odor, and can easily damage the pressure gauge if the hand is unsteady. Direct gas replacement can damage the internal components of the pressure gauge, incompletely replace particulate impurities, and unsatisfactory replacement results, shortening the service life of the equipment. To address these issues, a device for improving the gas replacement efficiency of a pressure gauge is proposed. Utility Model Content
