This practical technique is changed according to following three points：One is in skyscraper, 15 layers of middle position break pressure cistern, 21 generation
Record just for many years because the pressure-reducing valve exhaust apparatus of make-up pipe is ignored, promote waterpower liquid level indirect type ball-cock assembly and pressure-reducing valve to contain
Endlessly, structure discipline designer's y-type filter intense vibration can not work contentedly, the second is 13 layers of Boiler Room are as cheap as dirt old
The full of twists and turns leading sound of the similar stop valve runner of formula is frightful, looks into drawing and learns that the leading meter water column of static pressure 53 is not too high.
Thirdly below two layers of high-rise residential building, using feedwater plastic pressure pipe, be not used before pressure-reducing valve, plastic tube is safe and sound, but peace
After the pressure-reducing valve for having filled two layers of furred ceiling, hypotension is many, and the plastic pressure tube vibration after pressure-reducing valve is severe, and destruction on the contrary is permitted
Many plastic tubes, originally all pitch up plastic tube intensity not enough, are verified through paying a return visit, unit in charge of construction does not exist by national standard drawing at that time
Pressure-reducing valve, which is imported and exported, sets air bleeding valve ARV.Three bad problems of pipeline air exhaust water quality of the above, after simple process, have been obtained
Properly settle.It is noted that after the tap of Boiler Room 4 yuan/of unit price, the new type water nozzle for being replaced with 20 yuan/, making so far
It is quiet noiseless with over 11 years, remaining.
