Want to know about the internal structure of bellows pressure gauge? The instrument to introduce for you. Bellows pressure gauge is also called the micro pressure table. Suitable for measuring the explosion danger, crystallize, solidify, as well as to the copper and copper alloy non-corrosive effect of low pressure of the liquid, gas or steam, are small pressure measuring instrument, is a measure instrument around standard atmosphere pressure. It is mainly applied to boiler ventilating, gas pipeline, burning device and other similar devices. Constitute part of the bellows pressure gauge are: measurement system ( Including joints, corrugated box, etc. ) And drive mechanism ( Including the pull rod, gear transmission mechanism) , indicating device ( Including the pointer and dial) And the shell ( Including watchcase, lining and table cover glass or PC) 。 Working principle of bellows pressure gauge is based on the corrugated bellows under pressure measured medium, its free end produce elastic deformation, then through and amplification, transmission gear transmission mechanism by pointer fixed on gear shaft by measured values will be indicated on the dial out. And zero device, can easily adjust the zero. Through the above introduction, whether for had a deeper understanding of the bellows pressure gauge?
