品牌：RETZ/我們一直致力于流體控制和測控領域的持續創新，始于2005……自力式流量平衡閥通過調節閥芯位置來控制閥門的開啟面積，從而實現對流量的調節和平衡。當流量增加時，壓差也會增加，閥芯向上移動，閥門開啟面積增加，從而減小壓差，使流量達到平衡；當流量減小時，壓差也會減小，閥芯向下移動，閥門開啟面積減小，從而增加壓差，使流量達到平衡。這種閥門具有動態調節的能力，可根據流量變化實現實時調節，能夠廣泛應用于工業、建筑等領域中的管道系統。The self operated flow balance valve controls the opening area of the valve by adjusting the position of the valve core, thereby achieving flow regulation and balance. When the flow rate increases, the pressure difference also increases, and the valve core moves upwards, increasing the opening area of the valve, thereby reducing the pressure difference and achieving balance in the flow rate; When the flow rate decreases, the pressure difference also decreases, and the valve core moves downward, reducing the opening area of the valve, thereby increasing the pressure difference and achieving balance in the flow rate. This valve has the ability to dynamically adjust and can achieve real-time adjustment based on flow changes, and can be widely used in pipeline systems in industries, buildings, and other fields.

(可調流量平衡閥)自力式控制閥由自動調節閥瓣和手動調節閥瓣兩部分組成。當系統流體工作壓差超過300KPa時，為防止產生噪音，應采取措施將多余的壓差消耗掉 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

平衡閥不具備關斷功能，根據需要應另設關斷閥門。系統流體的工作壓力為P1，手動調節閥瓣的前后壓力分別為P2、P3。當手動調節閥瓣調到某一位置時，即人為確定了“設定流量”，以及相對應的固定（P2 -P3）值。當系統流量增大時，（P2-P3）的實際值超過了允許的給定值，此時自動調節閥瓣自動關小，直至流量重新維持到設定流量，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
