The flow rate and flow rate of the electric control valve manufacturer mainly depend on the diameter of the electric control valve, and are also related to the resistance of the electric control valve to the medium by the structure type of the electric control valve. connect.
In general, the flow rate is known and the flow rate can be determined empirically. The nominal diameter of the electric regulating valve can be calculated through the flow rate and flow.
The diameter of the electric regulating valve is the same, the structure is different, and the resistance of the fluid is also different. Under the same conditions, the larger the resistance coefficient of the valve, the more the flow rate and flow rate of the fluid passing through the valve will decrease; the smaller the valve resistance coefficient, the less the flow rate and flow rate of the fluid passing through the valve will decrease.
Control valve manufacturers
The selection of valve diameter should take into account the machining accuracy and dimensional deviation of the valve, as well as the influence of other factors. The valve diameter should have a certain margin, usually 15%. In practical work, the valve diameter depends on the diameter of the process pipeline.
The flow and flow rate of the electric control valve mainly depend on the diameter of the electric control valve, and it is also related to the resistance of the structure of the electric control valve to the medium. .
The flow channel area of the electric regulating valve has a direct relationship with the flow rate and flow rate, and the flow rate and flow rate are two interdependent quantities. When the flow rate is constant, the flow rate is large, the flow channel area can be smaller; the flow rate is small, the flow channel area can be larger. Conversely, the larger the flow channel area, the smaller the flow rate; the smaller the flow channel area, the larger the flow rate.
The flow rate of the medium is large, the diameter of the electric regulating valve can be smaller, but the resistance loss is large, and the electric regulating valve is easily damaged. If the flow rate is large, electrostatic effects will occur on flammable and explosive media, which will cause danger; if the flow rate is too small, the efficiency will be low and uneconomical. For viscous and explosive media, a smaller flow rate should be used. Oils and liquids with high viscosity select the flow rate according to the viscosity, generally 0.1 ~ 2m/s.
