品牌：RETZ/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……自力式流量平衡閥通過調(diào)節(jié)閥芯位置來控制閥門的開啟面積，從而實(shí)現(xiàn)對(duì)流量的調(diào)節(jié)和平衡。當(dāng)流量增加時(shí)，壓差也會(huì)增加，閥芯向上移動(dòng)，閥門開啟面積增加，從而減小壓差，使流量達(dá)到平衡；當(dāng)流量減小時(shí)，壓差也會(huì)減小，閥芯向下移動(dòng)，閥門開啟面積減小，從而增加壓差，使流量達(dá)到平衡。這種閥門具有動(dòng)態(tài)調(diào)節(jié)的能力，可根據(jù)流量變化實(shí)現(xiàn)實(shí)時(shí)調(diào)節(jié)，能夠廣泛應(yīng)用于工業(yè)、建筑等領(lǐng)域中的管道系統(tǒng)。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(diào)流量平衡閥)自力式控制閥由自動(dòng)調(diào)節(jié)閥瓣和手動(dòng)調(diào)節(jié)閥瓣兩部分組成。當(dāng)系統(tǒng)流體工作壓差超過300KPa時(shí)，為防止產(chǎn)生噪音，應(yīng)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(guān)斷功能，根據(jù)需要應(yīng)另設(shè)關(guān)斷閥門。系統(tǒng)流體的工作壓力為P1，手動(dòng)調(diào)節(jié)閥瓣的前后壓力分別為P2、P3。當(dāng)手動(dòng)調(diào)節(jié)閥瓣調(diào)到某一位置時(shí)，即人為確定了“設(shè)定流量”，以及相對(duì)應(yīng)的固定（P2 -P3）值。當(dāng)系統(tǒng)流量增大時(shí)，（P2-P3）的實(shí)際值超過了允許的給定值，此時(shí)自動(dòng)調(diào)節(jié)閥瓣自動(dòng)關(guān)小，直至流量重新維持到設(shè)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
