Description
Stainless steel diaphragm shock resistant pressure gauge y-100bfzznmz is used in petroleum, chemical industry, chemical fiber, dyeing and chemical industry, pharmaceutical industry, alkali food industry and other industries. Measuring corrosive, high viscosity, easy to crystallize, easy to solidify, high temperature, the pressure of liquid, gas or granular solid medium, and the occasions where the measuring medium must be prevented from directly entering the pressure instrument and sediment accumulation and easy to clean.
Structure principle
The pressure gauge is composed of a pressure guide system (including joint, spring tube, current limiting screw, etc.), a gear transmission mechanism, a number indicator device (pointer and dial) and a case (including case, cover, glass, etc.).The enclosure is air-tight structure, which can effectively protect the internal parts from environmental influence and pollution intrusion.For the instrument filled with liquid (usually silicone oil or glycerin) in the case, it can resist the vibration of the working environment and reduce the influence of the pulsation of medium pressure.
Decay resistance of diaphragm pressure gauges
The corrosion resistance of the diaphragm pressure gauge can be ensured by the proper selection of materials for the diaphragm, flange and sealing ring in contact with the measuring medium.
