وصف
Yb-100fzgy stainless steel diaphragm shock resistant pressure gauge is used in petroleum, chemical, chemical fiber, dyeing, pharmaceutical, alkali food and other industrial sectors. 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
Pressure gauge guided by pressure system(Including joints, spring tubes, current limiting screws, etc.)Gear transmission
mechanism, indicator device(Pointer and dial)And the shell.(Including watch case, watch cover, watch glass, etc.)Made up of. The shell is airtight structure, which can effectively protect the internal parts from environmental impact and filth intrusion. For filling the shell with liquid(Generally silicone oil or glycerin)The instrument can resist the vibration of the working environment and reduce the fluctuating effect of the medium pressure.
Corrosion resistance of diaphragm pressure gauges
The corrosion resistance of diaphragm pressure gauge can be guaranteed by selecting the material of diaphragm, flange and sealing ring in contact with the measuring medium.
