Valves control water flow balance analysis for occasions

 1, 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 balance 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 balancing valve.

     2, a thermal station, the second loop water flow balance

     In the thermal power stations or centralized boiler room hot water to a number of thermal stations of the system, to enable the thermal station to obtain required 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 balancing valve should be installed.

     3, district heating pipe network water flow balance

     District heating pipe network often 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 allow flow distribution does not meet design requirements, the proximal overheating, remote cold. Should be on each dry pipe and installation of balancing 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 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 mains, trunk mains, and risers (and the branch tube) must be installed on the balance valve.
