| Principle of Dynamic Balance Electric Control Valve |
Dynamic equilibrium is different from traditional electric control valve control valve of the new generation of electric products.
HVAC systems generally require electric flow control valve with linear characteristic curve, that flow changes and changes in the ratio of valve opening is a fixed value; the system load volatile variable flow system, electric control valve is also required so percentage flow characteristic curves, to meet in small flow adjustment is gentle, and sensitive in the large flow conditioning requirements.
Traditional electric control valve flow characteristics of an ideal curve is generally linear or other percentage. But in the actual work process, especially in the volatile variable system load flow system, due to fluctuations in the pressure difference control valve, the actual flow characteristics of the work of the flow curve will deviate from the ideal curve, so that electric adjustment Variation characteristics of the valve adjustment, reduced regulation accuracy. This work not only electrical valve control signals to control by the standard, but also by system pressure fluctuations, less able to resist the system interference. Large pressure fluctuations in the system or the right degree of valve is small, the regulation accuracy can not be adjusted even worse, leading to regulation of the temperature fluctuated, reaching less than a system of electric valve adjustment feature requests.
Dynamic equilibrium dynamic equilibrium with the electric control valve is electrically adjustable integrated product. It uses a new design concept, making the actual work of regulating valve in the system during the time when the pressure fluctuations can be a dynamic balance system pressure. Therefore, this dynamic balance of electrical work, the flow control valve characteristic curve and ideal flow curve is the same, not deviation. Special design to ensure the regulation of electric valve control signal only by the standards of the role, regardless of system pressure fluctuations, and the corresponding any electric valve opening position, the flow is unique and constant for the warm through air conditioning systems, which means that electric valve position in any regulation of heat transport (cold) volume is stable. Therefore, this electric valve particularly suitable for larger load change in the system variable flow system, with anti-interference ability, stable working conditions, regulate and high accuracy. Avoid the traditional electric control valve opening even in the same position, because the system pressure fluctuations, the flow is changing, the electric valve delivery hot (cold) the amount of instability, anti-interference ability, adjust the shortcomings of low precision.
