黃銅)內螺紋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進口內螺紋電動調節閥2.jpg
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）基本恆定，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 c**ity 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
