進口動態平衡電動調節閥 技術參數 Technical paramete

動態平衡電動調節閥結構分為流量調節結構和動態平衡結構兩部分  RETZ structure of dynamic balance electric control valve is divided into two parts: flow control structure and dynamic balance structure

流量調節結構可完成閥門流量的設定和調節，配合執行器可實現閥門的電動調節、開關功能 RETZ flow regulating structure can complete the setting and regulation of the valve flow, and cooperate with the actuator to realize the electric regulation and switching functions of the valve

動態平衡結構可實現閥門流量的動態平衡，該結構的核心部件為感壓膜片和彈簧，感壓膜片感應閥門入口和平衡閥芯內腔之間的壓（P1-P2），在此壓差作用下調節可變流道的流通面積，保持壓差（P1-P2）基本恒定，從而保持流量不變  RETZ dynamic balance structure can realize the dynamic balance of the valve flow. The core components of the structure are the pressure sensing membrane and the spring. The pressure sensing membrane senses the pressure (P1-P2) between the inlet of the valve and the inner cavity of the balance valve core. Under the effect of this pressure difference, the flow area of the variable flow channel is adjusted to keep the pressure difference (P1-P2) basically constant, so as to keep the flow unchanged

動態平衡電動調節閥安裝說明 Installation instructions

1.安裝前請詳細閱讀說明書，檢查產品型號和參數，根據要求設定工作電壓和輸入信號 Before installation, please read the instructions carefully, check the product model and parameters, and set the working voltage and input signal as required

2.盡可能保證垂直安裝，預留空間以方便維護 Vertical installation shall be ensured as much as possible, and space shall be reserved for convenient maintenance

3.安裝時應注意保證水流方向與閥體上箭頭所指方向一致 During installation, pay attention to ensure that the water flow direction is consistent with the direction indicated by the arrow on the valve body

4.建議設計系統旁路連通，灌裝時應該由旁路將管路中雜質沖洗干凈，否則可能會引起閥門堵塞 It is recommended to design the bypass connection of the system. During filling, the impurities in the pipeline should be flushed by the bypass, otherwise the valve may be blocked

5.安裝時應保證閥門前后預留一定長度的直管段，一般在進口預留管道直徑10倍長度的直管段，出口預留管道直徑5倍長度的直管段  During installation, a certain length of straight pipe section shall be reserved before and after the valve. Generally, a straight pipe section 10 times the length of the pipe diameter shall be reserved at the inlet and a straight pipe section 5 times the length of the pipe diameter shall be reserved at the outlet
