Technical field
The present invention relates to pressure reducer technical field, and in particular to a kind of pressure reducer structure for being easy to adjust.
Background technology
Because the gas pressure in the bottle is higher, and the pressure needed for gas welding and gas cutting and point of use is smaller, so needing with subtracting
The gas for the elevated pressures being stored in gas cylinder is reduced to low-pressure gas by depressor, and should ensure that required operating pressure from beginning extremely
Stable state is kept eventually.In a word, pressure reducer is that gases at high pressure are reduced into low-pressure gas and the pressure and flow of output gas is kept
Stablize constant adjusting means.
Action must be slow when oxygen cylinder has just opened deflation.If valve opening excessive velocities, pressure reducer working portion
Gas because by adiabatic compression, temperature is greatly improved, so there is a possibility that the part such as gum filler, rubber that organic material is made
Glue film-based fibre matter pad, which catches fire, to be burnt out, and pressure reducer can be made to burn out completely, and pressure gauge passes through the sensing element (bowden in table
Pipe, bellows, bellows) elastic deformation, then the switching mechanism of movement conducts pressure deformation to pointer in table, causes pointer
Rotate to show pressure, the too fast pressure gauge caused on pressure reducer of oxygen cylinder deflation exceeds elastic shape receiving excessive air pressure
The maximum of change, then failure.
