Relationship between valve diameter and medium flow rate
Classification:
Release Time：2021-03-01
Valve flow and flow rate mainly depends on the diameter of the valve, but also with the structure of the valve on the resistance of the medium, at the same time with the valve pressure, temperature and the concentration of the medium and other factors have a certain intrinsic link. The flow area of the valve is directly related to 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, and the flow channel area can be smaller; the flow rate is small, and the flow channel area can be larger. On the contrary, the flow channel area is large, its flow rate is small; the flow channel area is small, its flow rate is large. The flow rate of the medium is large, the valve diameter can be smaller, but the resistance loss is large, and the valve is easily damaged. The flow rate is large, which will produce electrostatic effect on flammable and explosive media, causing danger; the flow rate is too small, the efficiency is low, and it is not economical. For the medium with high viscosity and explosive, the flow rate should be smaller. Oil and liquid viscosity with the size of the viscosity of the choice of flow rate, generally take 0.1~2 m/s. In general, the flow rate is known and the flow rate can be determined empirically. The nominal diameter of the valve can be calculated by the flow rate and flow. The valve diameter is the same, its structure is different, the fluid resistance is not the same. Under the same conditions, the greater the resistance coefficient of the valve, the greater the flow rate of the fluid through the valve, the more the flow rate decreased; the smaller the resistance coefficient of the valve, the less the flow rate of the fluid through the valve, the less the flow rate decreased. predict more knowledge of the valve, can pay attention to the wuhan xietevalve.com valve official website: www.xietevalve.com.
