Balance valve for the occasion
1, the boiler (or chiller) flow balance In the boiler room (or chiller room), the general installation of several units in parallel, due to the different resistance between the units, causing inconsistencies in the flow through the various units, the unit can not play Installed the maximum output. In this case, a counterbalance valve (see Figure 1) should be installed at each boiler (or chiller) so that each unit can receive design flow to ensure that each unit is safe and up-to-date. 2, the first and second loop thermal balance of water flow in the thermal power station or centralized boiler room to a number of heat station heating Water system, in order to obtain the required thermal power station water flow, should be installed in each thermal loop on the return pipe side of the balance valve. In order to ensure that the secondary loop water flow is the design flow, the balance valve should also be installed on each secondary loop side of the thermal station. 3, District heating pipe network water flow balance Community heating pipe network often by a boiler room (or heat station) to a number of buildings heating. It consists of a main pipe, several main pipelines and branch pipes connected to the entrance of the building on the main pipelines. Because each building is located at a distance from the heat source, the lack of effective equipment to eliminate residual head pressure in the near-loop will result in a non-compliant flow distribution, overheating at the proximal end, and overcooling at the far end. Balance valves shall be installed at the entrance of each main pipe and each building to ensure the balance of flow between the main pipe and each building in the district (see Figure 3). 4, building heating (cold) pipe network water flow balance For demanding heating (cold) pipe network system, you need to ensure that all the risers (even branch) to achieve the design flow, then in the main pipe, main pipe And standpipe (and branch) should be installed on the balance valve (see Figure 4). 1, the boiler (or chiller) flow balance In the boiler room (or chiller room), the general installation of several units in parallel, due to the different resistance between the units, causing inconsistencies in the flow through the various units, the unit can not play Installed the maximum output.
