Description
本創作係關於一種隔膜式壓力錶，尤指一種用於測定氣體或液體壓力值之隔膜式壓力錶改良。This creation relates to a diaphragm type pressure gauge, and more particularly to a diaphragm pressure gauge for determining the pressure value of a gas or liquid.
習知的機械式壓力錶有巴登管壓力錶與隔膜式壓力錶等，巴登管壓力錶是由氣體或液體壓力進入巴登管，透過巴登管微量變動去帶動齒輪，透過齒輪比再帶動指針，進而顯示氣體或液體的壓力。而隔膜式壓力錶則由氣體或液體壓力進入錶內，推動錶內的隔膜，再由隔膜帶動彈簧，藉彈簧與扭簧的相對滑動帶動指針，同樣能顯示氣體或液體的壓力。Conventional mechanical pressure gauges include Baden tube pressure gauges and diaphragm pressure gauges. The Baden tube pressure gauges are fed into the Baden tube by gas or liquid pressure, and the gears are driven by the slight change of the Baden tube. The pointer is driven to display the pressure of the gas or liquid. The diaphragm pressure gauge enters the watch by the pressure of gas or liquid, pushes the diaphragm inside the watch, and then drives the spring by the diaphragm. The relative sliding of the spring and the torsion spring drives the pointer, which can also display the pressure of the gas or liquid.
