(可调流量平衡阀)进口自力式控制阀由自动调节阀瓣和手动调节阀瓣两部分组成。当系统流体工作压差超过300KPa时，为防止产生噪音，应采取措施将多余的压差消耗掉 RETZ self operated adjustable flow control valve (balance valve) is composed of two parts: automatic regulating valve disc and manual regulating valve disc. When the working pressure difference of system fluid exceeds 300kPa, measures shall be taken to consume the excess pressure difference to prevent noise

平衡阀不具备关断功能，根据需要应另设关断阀门。系统流体的工作压力为P1，手动调节阀瓣的前后压力分别为P2、P3。当手动调节阀瓣调到某一位置时，即人为确定了“设定流量”，以及相对应的固定（P2 -P3）值。当系统流量增大时，（P2-P3）的实际值超过了允许的给定值，此时自动调节阀瓣自动关小，直至流量重新维持到设定流量，反之亦然  RETZ balance valve does not have the shut-off function, and another shut-off valve shall be set as required. The working pressure of the system fluid is P1, and the front and rear pressures of the manual regulating valve disc are P2 and P3 respectively. When the manual regulating valve flap is adjusted to a certain position, the "set flow" and the corresponding fixed (P2 - P3) value are determined manually. When the system flow increases, the actual value of (P2-P3) exceeds the allowable given value, at this time, the automatic regulating valve disc automatically closes until the flow is maintained to the set flow again, and vice versa
