The Working Principle and Application of Stainless Steel Pressure Gauge

1. Working principle of stainless steel pressure gauge

The components of stainless steel pressure gauge: joint, stainless steel spring tube, sealing sheet, movement, connecting rod, dial (dial), pointer, sealing ring, case.

The measured pressure enters the spring tube through the joint, and under the action of pressure or vacuum, the spring tube produces elastic deformation, causing the end of the spring tube to shift. Its displacement is amplified by the mechanical transmission mechanism (connecting rod and movement) and transmitted to the indicating device, and then the pressure or vacuum value is indicated by the deflection of the pointer on the dial.

2. The application of stainless steel pressure gauge

The stainless steel pressure gauge is suitable for corrosive media, stainless steel component testing and harsh external corrosive environments. Stainless steel pressure gauges are widely used in petroleum, chemical, metallurgical and other industries.

3. The role of stainless steel pressure gauge elbow

It is used to protect the internal transmission mechanism from the damage of medium temperature and medium corrosion. Generally, if the medium is corrosive, a pressure gauge elbow must be added. When the medium temperature is higher than the set temperature, the pressure gauge elbow must be added. If the stainless steel pressure gauge is installed on the clean drinking water system, there is no need to increase it.

The bending of the stainless steel pressure gauge is used to reduce vibration and impact, and it also has a certain heat dissipation effect on the higher temperature medium. It is used to protect pressure gauges and reduce the temperature influence error of the stainless steel pressure gauge.

The damping screw at the orifice of the pressure gauge joint in the bent part of the stainless steel pressure gauge acts as a throttling buffer by reducing the flow area, and is mainly used for medium pressure pulses.
