《热水锅炉安全技术监察规程》(以下简称《热规》)明确规定,热水循环系统必须有可靠的定压措施和循环水的膨胀装置。《热规》明确了3种定压装置:一是采用高位水箱作定压装置;二是采用气体加压罐作定压装置:三是采用补给水泵作定压装置。采暖系统过去一直使用传统的补水箱及高位膨胀水箱定压。随着高层建筑的不断增多及供暖面积的不断增大,膨胀水箱的体积越来越大。且随着单位建设规模的不断扩大,每建一座高层建筑,膨胀
“Hot water boiler safety technology supervision regulations” (hereinafter referred to as “thermal regulation”) clearly stipulates that hot water circulation system must have reliable constant pressure measures and circulating water expansion device. “Thermal Regulation” defines the three kinds of constant pressure device: First, the use of high water tank for constant pressure device; the second is the use of gas pressure tank for constant pressure device: Third, the use of make-up pumps for constant pressure device. In the past, heating systems used conventional replenishment tanks and high expansion tanks to set the pressure. With the continuous increase of high-rise buildings and heating area continues to increase, the size of the expansion tank is getting bigger and bigger. And with the continuous expansion of construction units, each built a high-rise buildings, expansion
