| 蝶阀的开度与流量之间的关系，基本上呈线性比例变化。如果用于控制流量，其流量特性与配管的流阻也有密切关系，如两条管道安装阀门口径、形式等全相同，而管道损失系数不同，阀门的流量差别也会很大。如果阀门处于节流幅度较大状态，阀板的背面容易发生气蚀，有损坏阀门的可能，一般均在15°外使用。 The relationship between the opening and flow of butterfly valve is basically linear proportional change. If it is used to control the flow, its flow characteristics are closely related to the flow resistance of the piping. For example, the caliber and form of the valve installed in the two pipelines are the same, while the flow of the valve will be greatly different if the pipeline loss coefficient is different. If the valve is in a large throttling range, the back of the valve plate is prone to cavitation, which may damage the valve. Generally, it is used outside 15 °. |
