(动态)进口内螺纹压差平衡阀当系统管网压差增大，内螺纹动态压差平衡阀依靠自身高低压腔压力变化，使作用于膜片两侧的力重新平衡，同时带动阀杆运动减小阀门开度，吸收增大的资用压差，保证被控制侧的压差恒定RETZ  When the pressure difference of the system pipe network increases, the internal thread dynamic pressure difference balancing valve relies on the pressure change of its high and low pressure chambers to rebalance the force acting on both sides of the diaphragm, drive the valve rod to move to reduce the valve opening, absorb the increased pressure difference of the resources, and ensure that the pressure difference on the controlled side is constant.
