一、进口自力式蒸汽减压阀概述

进口自力式蒸汽减压阀（威盾VTON），Self pressure steam reducing valve，也叫进口自力式蒸汽压力控制阀，无需外加能源，利用被调介质自身能量为动力源引入执行机构控制阀芯位置，改变两端的压差和流量，使阀前（或阀后）压力稳定在所需要的压力值的调节阀。美国威盾VTON自力式压力调节阀具有动作灵敏，密封性好，压力设定点波动力小等优点，广泛应用于蒸汽介质减压稳压或泄压稳压的自动控制。
Self pressure steam reducing valve (VTON), also known as imported self operated steam pressure control valve, does not require external energy. It uses the energy of the regulated medium as the power source to introduce the actuator to control the position of the valve core, changes the pressure difference and flow rate at both ends, and stabilizes the pressure before (or after) the valve at the required pressure value. The American Weidun VTON self operated pressure regulating valve has the advantages of sensitive action, good sealing, and low pressure set point ripple force. It is widely used in automatic control of steam medium pressure reduction and stabilization or pressure relief and stabilization.

1. Self operated steam pressure reducing valves do not require external energy and can work in places without electricity or gas, which is both convenient and energy-saving.

2. The self operated steam pressure reducing valve has a narrow and intersecting pressure range, with high adjustment accuracy.

3. The pressure setting value of the self operated steam pressure reducing valve can be continuously set during operation.

4. The self operated steam pressure reducing valve regulates the pressure behind the valve, and the ratio of the pressure before and after the valve can be between 10:1 and 10:8.

5. Self operated steam pressure reducing valve rubber diaphragm type detection, with high measurement accuracy and sensitive action of the actuator.

6. The self operated steam pressure reducing valve adopts a pressure balancing mechanism, which makes the regulating valve responsive and precise in control.
