1. Boiler (or chiller) water flow balance
In a boiler room (or chiller room), several units are generally installed in parallel. Due to the different resistances between the units, the flow through each unit is inconsistent, so that the unit cannot exert the maximum output of the installed capacity. At this time, an Wear-Resistant Ball Valve should be installed at each boiler (or chiller) so that each unit can obtain the designed flow and ensure the safe and normal operation of each unit. When the chiller is connected to multiple cooling towers, each cooling tower should also be installed with an Wear-resistant Ball Valve.
2. Primary and secondary loop water flow balance of thermal power station
In a system where a thermal power station or a centralized boiler room supplies hot water to several thermal power stations, in order to enable each thermal power station to obtain the required water flow, an Wear-resistant
Ball Valve should be installed on the return pipe on the primary loop side of each thermal power station. In order to ensure that the water flow of each secondary loop is the designed flow, an Wear-resistant Ball Valve should also be installed on the secondary loop side of the thermal power station.
3. Water flow balance of community heating network
The community hot water network often supplies heat to several buildings from a boiler room (or heating station). It consists of a main pipe, several trunk pipes, and branches on each trunk pipe connected to the building entrance. Since each building is at a different distance from the heat source, if there is a lack of effective equipment to eliminate the residual pressure head of the near loop, the flow distribution will not meet the design requirements, the near end will be overheated, and the far end will be too cold. Wear-resistant Ball Valve should be installed at the entrance of each trunk pipe and each building to ensure the balance of flow between each trunk pipe and each building in the community.
4. Water flow balance of heating (cooling) network in buildings
For heating (cooling) network systems with higher requirements, it is necessary to ensure that all risers (even branches) reach the design flow. At this time, balancing valves should be installed on the main pipe, trunk pipe and riser (and branch pipe).
