进口内螺纹压差平衡阀 黄铜动态压差控制阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……

　　(动态)内螺纹压差平衡阀是一种自动恒定压差的的平衡阀，用于恒定空调或供热系统中控制阀、末端设备或管网之路供水之间的压差，避免管网压差变化对其动态干扰，实现动态水力平衡 retz The (dynamic) inlet internal thread differential pressurebalance valve is an automatic constant differential pressure balance valve,which is used for the pressure difference between the control valve, terminalequipment or water supply pipeline in the constant air conditioning orHydronics to avoid the dynamic interference of the pipeline network pressuredifference change and achieve dynamic hydraulic balance

　　(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 pressuredifference of the system pipe network increases, the internal thread dynamicpressure difference balancing valve relies on the pressure change of its highand low pressure chambers to rebalance the force acting on both sides of thediaphragm, drive the valve rod to move to reduce the valve opening, absorb theincreased pressure difference of the resources, and ensure that the pressuredifference on the controlled side is constant.
