Description
Technical field
This utility model relates to hydrogen pressure gauge technical field, a kind of practical hydrogen pressure gauge.
Background technology
Under normal temperature and pressure, hydrogen is that one is easily burnt, water white transparency, the gas of odorless, tasteless.Hydrogen
Being the gas that known density is minimum in the world, the quality of hydrogen only has the 1/14 of air, i.e. when 0 DEG C,
One standard atmosphere pressure, the density of hydrogen is 0.0899g/L.So hydrogen can be as dirigible, hydrogen
The filling gas (owing to hydrogen has combustibility, safety is the highest, and the existing multiplex helium of dirigible is filled) of ball.
Hydrogen is the material that relative molecular mass is minimum, is mainly used as reducing agent.Hydrogen (H2) is early than 16 generation
Recording and just manually prepared, the method used at that time is to be placed in strong acid by metal.Present industrial typically from
Natural gas or water gas hydrogen, and the method not using the electrolysis water of highly energy-consuming.The hydrogen prepared is a large amount of
Cracking reaction and production ammonia for petrochemical industry.Hydrogen molecule can enter in the most polymetallic lattice,
Cause " hydrogen embrittlement " phenomenon so that the storage tank of hydrogen and pipeline need to use special material (such as Meng Naier
Alloy), design the most complicated.Hydrogen pressure gauge is suitable for the pressure measuring hydrogen gas medium.Belong to special
With Pressure gauge, according to industrial needs, hydrogen pressure gauge requires to forbid to contact oil substances (prohibiting oil),
Some to mark special sign on dial plate.Traditional hydrogen pressure gauge function is more single, and does not set
Being equipped with alarm, when there is hydrogen gas leakage, being susceptible to explosion accident.
