Model of midline butterfly valve The midline butterfly valve is actually a butterfly valve The structural form of the midline butterfly valve is a sealed central vertical plate, the whole butterfly plate and the valve seat are concentric within 360 ° circumference (midline), with two-way sealing function, so let's summarize the model of the midline butterfly valve

4. Investigate the flow condition upstream of the sensor and check the condition of the inner wall of the sensor measurement channel. The upstream flow condition of the sensor is often limited by the installation space and deviates from the specified requirements. For example, there is no straight pipe section of sufficient length close to the choke that generates turbulence, which will introduce factors affecting the accuracy of measurement. In particular, if the upstream of the proximity sensor is equipped with a regulating valve or a gate valve that is not fully opened, the only way to completely solve the problem is to change the installation position of the sensor; Install flow adjustment when the length of upstream straight pipe section is insufficient? quot; It can only be partially improved.
