武汉百士自动化设备有限公司专注于液压、气动、工控自动化备件销售，热诚欢迎新老客户咨询购买！

流量阀适用于需要进行流量控制的水系统中，尤其适合于供热，空调等非腐蚀性液体介质的流量控制；安装在水系统中，经运行前的一次调节，即可使系统流量自动恒定在要求的设定值。自动消除水系统中因各种因素引起的水力失调现象，保持用户所需流量，克服“冷热不均”提高供热，空调的室温，提高系统能效，实现节能，是供热、空调系统实现“计量收费”的理想配套产品。

流量阀的作用是在阀的进出口压差变化的情况下，利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节，从而控制执行元件的运动速度。维持通过的流量恒定，从而维持与之串联的被控对象(如一个环路、一个用户、一台设备等，下同)的流量恒定。管网中应用流量阀，可直接根据设计来设定流量，阀门可在水压作用下，自动消除管线的剩余压头及压力波动所引起的流量偏差。流量阀的名称较多，如自力式流量平衡阀、定流量阀、动态平衡阀等。各种类型的流量阀，结构各有不同，但工作原理相似。
