品牌：RETZ/我們一直致力于流體控制和測(cè)控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……定流量閥、動(dòng)態(tài)流量平衡閥主要用于解決流體輸配管網(wǎng)水力失調(diào)的難題，當(dāng)系統(tǒng)壓力在工作壓差范圍內(nèi)波動(dòng)時(shí)它能動(dòng)態(tài)地平衡這種變化而保持所在管道的流量恒定retz The constant flow valve and dynamic flow balance valve are mainly used to solve the problem of hydraulic imbalance in fluid transmission and distribution pipelines. When the system pressure fluctuates within the working pressure difference range, they can dynamically balance this change and maintain a constant flow rate in the pipeline where they are located

進(jìn)口動(dòng)態(tài)流量平衡閥技術(shù)參數(shù) Technical paramete

1.壓差低于最小工作壓差時(shí)，閥芯全開(kāi)，與孔板功能一致，流量隨壓差增大而增大（圖1）When the pressure difference is lower than the minimum working pressure difference, the valve core is fully opened, which is consistent with the function of the orifice plate, and the flow increases with the increase of the pressure difference (Fig. 1)

2.壓差在工作壓差范圍內(nèi)時(shí)，閥芯根據(jù)系統(tǒng)壓差的變化改變開(kāi)度，保證設(shè)計(jì)流量在±5%的偏差范圍內(nèi)變化（圖2）RETZ When the pressure difference is within the working pressure difference range, the valve core changes the opening according to the change of the system pressure difference to ensure that the design flow changes within the deviation range of ± 5% (Fig. 2)

3.壓差大于工作壓差時(shí)，閥芯開(kāi)度最小，與孔板功能一致，流量隨壓差增大而增大（圖3）When the pressure difference is greater than the maximum working pressure difference, the opening of the valve core is the smallest, which is consistent with the function of the orifice plate. The flow increases with the increase of the pressure difference (Fig. 3)

4.在工作壓差范圍內(nèi)，流量保持恒定（圖4）The flow rate remains constant in the range of operating differential pressure (Figure 4)

進(jìn)口動(dòng)態(tài)流量平衡閥性能特點(diǎn)∶ Performance characteristics

1.動(dòng)態(tài)平衡∶當(dāng)系統(tǒng)壓差產(chǎn)生波動(dòng)時(shí)，閥芯自動(dòng)調(diào)整可變流道開(kāi)度，能實(shí)現(xiàn)被控區(qū)域恒定流量RETZ Dynamic balance: when the pressure difference of the system fluctuates, the valve core automatically adjusts the opening of the variable flow channel, which can realize the constant flow in the controlled area

2.準(zhǔn)確校準(zhǔn)的閥芯可確保流量恒定在±5%的偏差范圍內(nèi) The precisely calibrated spool ensures that the flow is constant within ± 5% of the deviation

3.流量出廠設(shè)定，每個(gè)尺寸具有多個(gè)壓差范圍可供選擇  Flow factory setting, each size has multiple pressure difference ranges for selection

4.不需現(xiàn)場(chǎng)調(diào)試，減少人力成本  No on-site commissioning is required to reduce labor cost

5.系統(tǒng)變化后，不需對(duì)系統(tǒng)進(jìn)行再平衡設(shè)計(jì)  After the system changes, there is no need to rebalance the system

安裝說(shuō)明 Installation instructions

1.根據(jù)閥門(mén)選型正確使用閥門(mén)，避免用錯(cuò)流量及壓差 Use the valve correctly according to the valve selection to avoid wrong flow and pressure difference

2.注意系統(tǒng)管道排氣，系統(tǒng)存氣，可能會(huì)引起介質(zhì)堵塞、調(diào)節(jié)功能失效、或噪聲過(guò)大 Pay attention to the exhaust of the system pipe and the air in the system, which may cause medium blockage, regulation function failure or excessive noise

3.該閥門(mén)可水平安裝亦可垂直安裝，安裝過(guò)程中應(yīng)注意介質(zhì)流向，方向裝反會(huì)失去功能 The valve can be installed horizontally or vertically. Pay attention to the flow direction of medium during installation. If the direction is reversed, it will lose its function

4.閥門(mén)進(jìn)水端建議加過(guò)濾器或清洗管路，可避免大顆粒雜質(zhì)堵塞閥門(mén)控制元件 It is recommended to add a filter or clean the pipeline at the water inlet end of the valve to avoid blocking the control element of the valve with large particles

5.注意檢測(cè)孔的保護(hù)，碰掉或變形會(huì)引起泄露或以后的維護(hù)困難 Pay attention to the protection of the inspection hole. If it is touched or deformed, it will cause leakage or later maintenance difficulties
