RETZ工业/美国瑞茨,我们一直致力于楼宇节能领域的持续创新,始于2005……自力式流量平衡阀通过调节阀芯位置来控制阀门的开启面积，从而实现对流量的调节和平衡。当流量增加时，压差也会增加，阀芯向上移动，阀门开启面积增加，从而减小压差，使流量达到平衡；当流量减小时，压差也会减小，阀芯向下移动，阀门开启面积减小，从而增加压差，使流量达到平衡。这种阀门具有动态调节的能力，可根据流量变化实现实时调节，能够广泛应用于工业、建筑等领域中的管道系统。The self operated flow balance valvecontrols the opening area of the valve by adjusting the position of the valvecore, thereby achieving flow regulation and balance. When the flow rateincreases, the pressure difference also increases, and the valve core moves upwards,increasing the opening area of the valve, thereby reducing the pressuredifference and achieving balance in the flow rate; When the flow ratedecreases, the pressure difference also decreases, and the valve core movesdownward, reducing the opening area of the valve, thereby increasing thepressure difference and achieving balance in the flow rate. This valve has theability to dynamically adjust and can achieve real-time adjustment based onflow changes, and can be widely used in pipeline systems in industries,buildings, and other fields.

(可调流量平衡阀)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 controlvalve (balance valve) is composed of two parts: automatic regulating valve discand manual regulating valve disc. When the working pressure difference ofsystem fluid exceeds 300kPa, measures shall be taken to consume the excesspressure 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 RETZbalance valve does not have the shut-off function, and another shut-off valveshall be set as required. The working pressure of the system fluid is P1, andthe front and rear pressures of the manual regulating valve disc are P2 and P3respectively. When the manual regulating valve flap is adjusted to a certainposition, the "set flow" and the corresponding fixed (P2 - P3) valueare determined manually. When the system flow increases, the actual value of(P2-P3) exceeds the allowable given value, at this time, the automaticregulating valve disc automatically closes until the flow is maintained to theset flow again, and vice versa
