(流量控制閥)進口靜態平衡閥可代替截止閥關斷功能，產品攜帶有測量接頭，方便與測量設備的快速連接，節省調試時間，具有最大行程鎖定功能，當系統調試后可將鎖定裝置開啟，方便日后可關閉靜態閥進行管路維護與檢修，結束后可以直接將閥門恢復到設定好的最大行程處，避免二次調試RETZ The static balance valve can replace the shut-off function of the stop valve. The product carries a measuring connector, which is convenient for quick connection with the measuring equipment, saves debugging time, and has the maximum stroke locking function. When the system is commissioned, the locking device can be opened, which is convenient for closing the static valve for pipeline maintenance and repair in the future. After the completion, the valve can be directly restored to the set maximum stroke to avoid secondary debugging.

測量精度示意圖  Schematic diagram of measurement accuracy

靜態平衡閥在開度≥50%時，誤差不得大于±5%；10%≤開度≤50%時，誤差不得大于±10%。故在產品選型時，建議設計流量下閥門開度大于50%為宜，同時為保證現場調試余量，閥門盡量設置在75%開度左右 RETZWhen the opening of static balance valve is ≥ 50%, the error shall not be greater than ± 5%; When 10% ≤ opening ≤ 50%, the error shall not be greater than ± 10%. Therefore, during product selection, it is suggested that the valve opening should be greater than 50% under the design flow. Meanwhile, in order to ensure the on-site commissioning margin, the valve should be set at about 75% opening as far as possible.

安裝說明 Installation instructions

靜態平衡閥安裝前應確保系統內無雜物，請注意介質的流向與閥體上的流向標記一致，一般安裝于系統的回水管，當與動態壓差平衡閥配套使用時，安裝于供水管。通常與彎頭或水泵連接時，需要保持一定的直管段安裝距離；當與彎頭連接時，遵循閥前5d，閥后2d原則；當與水泵連接時，遵循10d原則。Before installing the static balance valve, ensure that there are no sundries in the system. Please note that the flow direction of the medium is consistent with the flow direction mark on the valve body. It is generally installed in the return pipe of the system. When it is used with the dynamic differential pressure balance valve, it is installed in the water supply pipe. Generally, when connecting with elbow or water pump, a certain installation distance of straight pipe section shall be maintained; When connected with the elbow, follow the principle of 5D in front of the valve and 2D behind the valve; When connected with the water pump, follow the 10d principle.
