Stainless Steel Pressure Gauge Structural Principle
- Sep 18, 2017 -

Stainless steel pressure gauge is widely used in petroleum, chemical, chemical fiber, metallurgy, power plants, food and other industrial sectors of the corrosion resistance, high temperature requirements of the process of measuring a variety of fluid medium pressure

Structural principle: stainless steel pressure gauge by the pressure system (including joints, spring tube, current limiting screws, etc.), gear transmission, the number of devices (pointer and dial) and shell (including case, watch cover, table glass, etc.) .

The pressure gauge is elastically deformed by the stainless steel sensor element (Bourdon tube, diaphragm, bellows) in the table, and then the elastic movement of the table movement is guided to the pointer, causing the pointer to turn to show the pressure. For the instrument in the shell filled with liquid (usually silicone oil or glycerin), it is possible to resist the vibration of the working environment and reduce the fluctuation of the medium pressure.

Installation Precautions:

1, the choice of pressure point, the selected pressure point can reflect the measured pressure of the real situation.

(1) to be selected in the measured flow of the tube part of the line, do not choose in the pipeline turning, bifurcation, dead ends or other easy to form a whirlpool.

(2) When measuring the pressure of the flow medium, make sure that the pressure point is perpendicular to the flow direction and remove the drilling burr.

(3) to measure the liquid pressure, the pressure point should be in the lower part of the pipeline, so that the pressure tube does not accumulate gas, measuring gas, the pressure point should be above the pipeline, so that the pressure tube does not accumulate liquid.

Use and order instructions

(1) Seismic stainless steel pressure gauge does not apply to the outside world with chlorine, nitric acid and chlorinated oxygen and other strengthening agent environment.

(2) stainless steel pressure gauge shell to be sprayed PTEE Teflon coating, when ordering.

(3) Please indicate gauge stainless steel threaded joint for special requirements.

(4) All stainless steel pressure gauge is divided into ordinary type and shock type.

(5) Please specify the name, model and measurement limit

Table with direct contact fittings and pressure-sensitive components of materials, using icr18Ni9T, Ocr18Ni12Mo2Ti, sus316, the structure of the whole sealed, stainless steel pressure gauge has a strong anti-corrosion of the measured medium corrosion and environmental corrosion resistance. Stainless steel pressure gauge for corrosive strong stainless steel components for the detection of medium and poor external corrosion environment, stainless steel pressure gauge is widely used in petroleum, chemical, metallurgical and other industries.
