The valve flow coefficient is a measure of the valve flow capacity index, the greater the flow coefficient of the fluid through the valve when the pressure loss of the smaller. Can measure fluid flow resistance coefficient of the valve through the valve after the main power consumption. Flow coefficient of the valve, the flow resistance coefficient depends on the valve size, form, structure, flow resistance coefficient of the valve flow test valve product improvement, for the rational design of fluid engineering systems to reduce power consumption, to provide valid data.
The device main technical parameters and functions
According to the requirements of the construction side of the test device, the main technical parameters of this paper the design of the test device as follows:
(1) to provide a loop maximum pressure: 2.5MPa;
② temperature: room temperature (≤ 40 ℃);
③ Maximum flow: 150m3 / h;
The ④ valve maximum diameter: 100mm;
⑤ loop medium: deionized water.
The main function of the test device: When the water reaches a steady flow through the valve, the valve flow coefficient and the coefficient of flow resistance, flow test and flow resistance test to meet JB/T5296-1991 "universal valve flow coefficient and flow resistance coefficient of determination the requirements of the test method ".
