1, dbb valve boiler (or chiller) water flow balance in the boiler room (or cold room), the general parallel installation of several units, as between the various units have different resistance, causing the flow through the unit is inconsistent, and the unit can not play the largest installed capacity to contribute. At this point should be on each boiler (or chiller) to install dbb valve, so that each unit can be designed with a capacity for each unit to ensure safe and normal operation. Chillers to connect more than one cooling tower, cooling tower should also be installed on each .2 dbb valve, dbb valve of a thermal station, the second loop water flow balance thermal power stations or centralized boiler room to heat water in a number of thermal stations system, in order to enable the thermal station if requested, water flow, should at all stations in a loop heat pipe installed on the back side of balance valve. To ensure that all secondary-loop water flow for the design flow, thermal station side of the secondary loop dbb valve should be installed. 3, district heating pipe network water flow dbb valve district heating pipe network is often balanced by a boiler room (or heat station) to a number of blocks of buildings heating. From the mains, trunk mains, as well as a number of dry pipe connected with the construction branch of the entrance tube. Because each building near and far away from the heat, if the lack of an effective device to eliminate the residual pressure head near the loop will bring dbb valve flow distribution does not meet design requirements, the proximal overheating, remote cold. Should be on each dry pipe and installation of dbb valve entrance of each building to ensure that each district and the blocks of buildings between the main pipe flow balance. 4, the building heating (cold) water-balance valve flow balance pipe network that require a higher heating (cooling) systems, and the need to ensure that all of the risers (or branch pipe) to meet the design flow, when the Explorer, dry pipes and risers (and the branch tube) must be installed on the dbb valve.
