Description

Technical Field

[0001] The utility model relates to the technical field of instrument panels, in particular to an anti-corrosion diaphragm pressure gauge. Background Art

[0002] A diaphragm pressure gauge is an instrument used to measure the pressure of liquids or gases. It uses a soft diaphragm to separate the measured medium from the measuring mechanism inside the pressure gauge. When the pressure of the medium acts on the diaphragm, the diaphragm deforms, which in turn causes the measuring mechanism (usually a spring or pressure sensor) to change accordingly. This change is converted into a readable pressure value for users to monitor and control.

[0003] Diaphragm pressure gauges are often used in industrial production processes of liquids or gases to ensure that the pressure inside pipelines, containers or equipment is within a safe range. They are widely used in chemical, petroleum, pharmaceutical, food processing and other fields.

[0004] The diaphragm pressure gauge needs to be anti-corrosive mainly because in the industrial production environment, the medium may contain corrosive substances, such as corrosive chemicals, salt water, acidic solutions, etc. If these media directly contact the parts or components of the pressure gauge, it may cause damage or failure of the pressure gauge, thereby affecting the accurate measurement of pressure and the safe operation of the equipment; therefore, it does not meet the existing needs, and we propose an anti-corrosion diaphragm pressure gauge. Utility Model Content

An adjusting rack 421 corresponding to the adjusting gear 531 is provided in the adjusting slot 420, and the adjusting rack 421 is meshed with the adjusting gear 531.

[0025] A telescopic rod 540 is installed in the inner sleeve 400, and a spring 541 for auxiliary adjustment is arranged on the outer sleeve of the telescopic rod 540, one end of the spring 541 contacts the bottom of the fixing seat 300, and the other end of the spring 541 contacts the inner wall of the outer sleeve 500, and the telescopic rod 540 and the spring 541 are also located in the outer sleeve 500.

[0028] The fixing seat 300 is divided into a first seat 310 and a second seat 320. The first seat 310 is located on the upper side of the second seat 320.
