The Relationship Between Valve Diameter And Medium Flow Rate
1. The flow rate and flow rate of a valve mainly depend on the diameter of the valve, and are also related to the resistance of the valve structure to the medium. At the same time, they are inherently related to various factors such as valve pressure, temperature, and medium concentration.
2. The flow channel area of a valve is directly related to the flow rate and flow rate, which are interdependent quantities. When the flow rate is constant, the larger the flow rate, the smaller the channel area; If the flow rate is small, the flow channel area can be larger. On the contrary, if the flow channel area is large, its flow velocity is small; The flow channel has a small area and a high flow velocity.
3. The flow rate of the medium is high, and the valve diameter can be smaller, but the resistance loss is large, and the valve is prone to damage. High flow rate can cause electrostatic effects on flammable and explosive media, causing danger; The flow rate is too small, the efficiency is low, and it is not economical. For media with high viscosity and explosive properties, a smaller flow rate should be taken. The flow rate of oil and liquids with high viscosity is selected according to the viscosity, generally ranging from 0.1 to 2m/s.
4. In general, the flow rate is known, and the flow rate can be determined by experience. The nominal diameter of the valve can be calculated through flow rate and flow rate.
5. Valves with the same diameter have different structural types and fluid resistance. 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 decrease; The smaller the resistance coefficient of the valve, the less the decrease in flow rate and flow rate of the fluid passing through the valve.
