Pressure drop across the electromagnetic pulse valve and the flow of the components

Flow characteristics of the electromagnetic pulse valve is the pressure across the electromagnetic pulse valve Importers drop relationship between the flow through the element with. There are several ways to describe the electromagnetic pulse valve flow characteristics:

1. The effective cross-sectional area S value in incompressible flow regime : applicable to components with a pressure drop of less than 2% .
2 , the sound velocity of the C value and the critical pressure ratio b value: the accuracy of the measurement is difficult to ensure at the same time.
3. Pressure drop at rated flow: This indicator also only reflects the flow characteristics under incompressible flow conditions. 1.3 Flow - pressure drop characteristic curve: Used for components in incompressible flow regimes.
4. The effective cross-sectional area S value under flow condition: It is applicable to components under compressible flow conditions.
5 , circulation capacity Cv value and Kv value: It is reasonable to use the relationship between flow and pressure drop when calculating incompressible flow.
6. Flow coefficient Cd : The position of the small interface of the component is not easy to determine, so it is difficult to accurately determine the relevant parameters.
7. The effective sectional area S value and the critical pressure ratio b value under the flow state of the plug : It can completely determine the flow characteristics of the components in the compressible flow state.
