一、进口蒸汽减压阀产品概述

进口蒸汽减压阀（威盾VTON），steam reducing valve，也叫蒸汽调压阀，是指用于蒸汽管道系统，通过导阀感应阀后压力的变化，调节主阀的阀芯开度，将蒸汽管道的进口压力减至某一需要的出口压力，并稳定在压力值的阀门。此阀依靠蒸汽介质本身的能量,使出口压力自动膜片采用了新型材料，并大大加工了工作面积，因此阀门上游压力或下游负荷细微的变化都能及时准确的反馈到主阀膜片，来调节主阀的开度，确保下游压力的稳定。

Steam reducing valve (VTON), also known as steam pressure regulating valve, refers to a valve used in steam pipeline systems. By sensing the pressure changes after the valve through a pilot valve, the valve core opening of the main valve is adjusted to reduce the inlet pressure of the steam pipeline to a certain required outlet pressure and stabilize it at the pressure value. This valve relies on the energy of the steam medium itself to make the outlet pressure automatic diaphragm use new materials and greatly process the working area. Therefore, subtle changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.
