进口自力式流量平衡阀 可调流量控制阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……

　　进口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 valve controls the opening area ofthe valve by adjusting the position of the valve core, thereby achieving flowregulation and balance. When the flow rate increases, the pressure differencealso increases, and the valve core moves upwards, increasing the opening areaof the valve, thereby reducing the pressure difference and achieving balance inthe flow rate; When the flow rate decreases, the pressure difference alsodecreases, and the valve core moves downward, reducing the opening area of thevalve, thereby increasing the pressure difference and achieving balance in theflow rate. This valve has the ability to dynamically adjust and can achievereal-time adjustment based on flow changes, and can be widely used in pipelinesystems 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 control valve (balance valve) is composed oftwo parts: automatic regulating valve disc and manual regulating valve disc.When the working pressure difference of system fluid exceeds 300kPa, measuresshall 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 nothave the shut-off function, and another shut-off valve shall be set asrequired. The working pressure of the system fluid is P1, and the front andrear 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 determinedmanually. When the system flow increases, the actual value of (P2-P3) exceedsthe allowable given value, at this time, the automatic regulating valve discautomatically closes until the flow is maintained to the set flow again, andvice versa
