Pressure uses impulse formula mount scheme, and to carry out back-blowing to this measurement pipeline and draw to avoid the reduction of long range impulse temperature
Condensation or crystallization are played, using a kind of gas pressure measurement instrument back-blowing preheating device of the utility model, is connect in back-blowing pipeline
Enter before measuring the threeway that pipeline is connect with manometer, in the heat preservation of high temperature process lines or equipment where pressure pressure ozzle
The temperature for improving back-blowing in layer with process fluid heat exchange using several (3~5 desirable) U-shaped curved forms, to avoid because of instrument
Process gas condensation or crystallization caused by table air temperature is relatively low.Back-blowing pipeline realizes opening for back-blowing from device to set switch valve
It opens and closes, if control is adjusted to blowback air quantity in flow-limiting valve, if check-valves prevents process gas anti-channeling, and set after check-valves
Pressure gauge is observed instrument wind pressure on the spot.And pipeline or the pipeline section of insulation of equipment layer access threeway are said to reverse-blow pipe
And pressure pressure ozzle does instrument piping insulating layer to the pipe fitting between threeway, to reduce thermal loss.The utility model is ingenious
Using process fluid self-energy as preheating heat source, it is simple in structure, not only reduce preliminary project cost of investment, while
Reduce later stage operating cost.
