Automatic constant pressure valve and electric control valve performance profile

Static balance valve is actually a kind of artificially set the opening of the globe valve. Through artificial adjustment of local resistance to solve the air conditioning water piping system hydraulic balance part of the system during the initial test, all the valves in the system are at a certain opening, commissioning staff based on the original mathematical model of each static balance valve one by one However, for different water systems, the resistance distribution curve is absolutely not the same and can not be measured. Therefore, the static balance valve can only be fuzzy and qualitative control Water flow. For a variable flow air conditioning water system, the change of water volume per air conditioner box is random. The pressure of the entire pipeline system is also unpredictable. The change of the opening degree of the control valve is also random. Therefore, from formula I, Valve + Electric Control Valve Performance Introduction When the system pressure changes, the automatic constant pressure differential valve + electric control valve is currently used to solve the balance of air conditioning water system a very good way. Constant pressure differential valve can change its own flow area so that the pressure across the electric control valve remains the same, so that the CV value of the control valve is always one, so as to ensure that the electric control valve has been operating in the best conditions, the real The change in water volume is temperature dependent and pressure independent, ensuring that the amount of water entering the air conditioner box is the amount of water you need at any one time. Plexus makes the system more superior performance, more convenient to maintain. The use of automatic pressure differential valve at the end of the system + electric control valve eliminates the need for extensive use of balancing valves in stratified control. The use of an automatic constant pressure differential valve + electric control valve at the end of the system eliminates the need for extensive use in stratification Balance valve in control. So you can make the system more superior performance, more convenient to maintain. Automatic constant pressure differential valve + electric control valve is a variable flow air conditioning water system, an important guarantee of hydraulic balance, automatic constant pressure differential valve + electric variable flow air conditioning water system is an important guarantee of hydraulic balance. The use of automatic balancing proportional integral control valves in the system can bring you numerous benefits. 1. Because there is no need for system debugging, so save a lot of trouble, save a lot of time and shorten the completion date; 2. Because you do not have to use the valve group and the valve for stratification control, so you save more pipe , Insulation materials and equipment costs and time; 3. The water system at all times in a balanced state, so regardless of installment equipment or equipment used in stages will not affect the balance of the water system. 4 even after the project or put into operation due to Changes in some uses require changes to the design of the water system in some areas and will not affect the water system design in other areas and will not affect the water system balance in other areas. 5. Since the entire system is in a state of dynamic equilibrium, The pump will be the most energy-efficient operation, saving a lot of operation and maintenance costs. 6. Because the system flow balance is automatic. Make the device more convenient and maintenance, and eliminate the possibility of human errors may undermine the balance.
