Static balance valve is actually a set can be artificially precise cut-off valve opening. Local resistance by artificially adjusting air-conditioning water system to solve part of the hydraulic piping systems balance the early commissioning, the system all the valves are in an opening, commissioning a mathematical model based on the original one by one for each static balance valve the opening of the settings (set up after the valve opening is some value) but different water distribution system, the resistance curve is definitely not the same but the result can not be measured, the static balancing valve only vague qualitative control of water flow. A variable flow air conditioning water systems, air-conditioned box for each water change is random changes in the pressure piping system is unpredictable control valve opening degree of change is also random from the equation I First, the automatic constant pressure differential valve + electric control valve performance Introduction When the system pressure changes, the automatic constant pressure differential valve + electric control valve is used to solve the air conditioning system to balance a very good idea. Constant pressure differential valve can change its own flow area at both ends of the electric control valve pressure remains unchanged, so that the control valve CV value is always one, so as to ensure electric control valve has been in the best condition to run, the real make changes in water temperature only has nothing to do with the pressure, can guarantee the amount of water into the air box at any one time is the amount of water you need. Bundle leaving the system better performance, easier to maintain. The end of the system with automatic constant pressure differential valve + electric control valve eliminates the need for extensive use of the balance valve in the hierarchical control system with automatic constant pressure difference between the end of the valve + electric control valve eliminates the need for extensive use in the hierarchical Control of the balance valve. So you can make the system better performance, easier to maintain. Automatic constant pressure differential valve + electric control valve is variable flow air conditioning system an important guarantee for water balance, automatic constant pressure differential valve + electric control valve is a hydraulic variable flow air conditioning system an important guarantee for the balance. Automatic balancing system using proportional integral control valve can bring you many benefits. 1. By eliminating the need for system debugging. So save a lot of trouble, saving a lot of time and shorten the completion date; 2. Because they are not used for hierarchical control valve unit and valve. So you save more pipes, insulation materials and installation costs and time; 3. The water system is in balance at all times. Therefore, regardless of device or equipment in stages stage construction will not affect the balance of the water system.
