。 3, pay attention to the new system, and the balance of the original system: when the installation has a balanced valve is the new system of petition in heating (original Cold) Network, be sure to pay attention to the new system and old system water distribution equilibrium problems, so that new system installed the balanced valve ( Or modification system) Water resistance is higher than the original system, any but the flow of water. 1, the installation location: balancing valve can be installed on the pipes, also can be installed on the way back to the water pipe ( Each loop in the need to install a) 。 Because the installed the balanced valve, don't need to install the valve. 2, try to install on the straight pipe: because the balanced valve with flow metering function, to make the flow through the valve before and after water safe, ensure the surveying precision, in conditions allow things conditions should try to balance valve installed on the straight pipe. Static balancing valve should be used in the system can at: main branch, riser, level and end use, the effect with the pipe. For a ring roadside thermal power station, Marine valve, adjusting for convenient equilibrium proposal will be balanced valve installed on the way of return pipe of water temperature is low. In the process of pipe network system normal operation, should not change the balanced valve opening, especially the opening should not change the lock. Balancing valve on the main, should be installed in the water supply main pump (after Downstream of the pump) In order to avoid because water pump ( After the Industrial Valves) Pressure is too low, the possible water pump cavitation phenomenon. 5, don't need to install the valve: when check repair a loop, the loop can be balanced valve closed, the balanced valve has the utility to cut off the water valve check returned again after completion of repair the original lock position. Static balancing valve is also called a balanced valve, balanced valve manually, digital locked balance valve, two position regulator, etc. , it is after the change of valve core and valve seat space ( The opening) Debug the valve Kv ( flow experienced) To change the flow resistance of flow through the valve to achieve the purpose of the flow adjustment, its utility object is the resistance of the system, eliminate injustice, the phenomenon of balance system resistance, thus to the proportion of new water in accordance with the preset calculating equilibrium, each branch in proportion to increase or decrease at the same time. 4, should not change the balance valve opening: completion of pipe network system installation, and testing conditions, using the special intelligent instrument to all balanced valve adjustment setting, and lock the valve opening, pipeline successfully hydrodynamic condition is balanced. Q: how accurate installation using the balanced valve? Answer: balancing valve is in the hydrodynamic conditions, dynamic and static balance adjustment valve. 6, system add ( Or eliminate) Loop should from the new adjustment setting: when added in the pipeline network system ( Or eliminate) When the loop, besides should increase ( Or close) Corresponding balance valve, in principle, all new balance valve and balance valve in original system loop should be the new adjustment setting ( Branch in loop of the balanced valve don't need a new debugging) 。 Balancing valve can be divided into types: with the doctrine of the static balancing valves and dynamic balancing valve and differential pressure is independent of the balanced valve. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
