气体稳压阀是一种气动式控制器,把它接在气路中,无需外界供给能源,靠工作介质本身的能量,即可输出稳定的压力。稳压阀适用于要求对气体压力或气体流量进行精确控制的场合。例如:各类色谱仪、金属中气体分析仪、原子吸收光谱仪,总有机碳分析仪等。目前国内外使用的稳压阀都是根据相同原理设计的,主要区别是感受元件不同。常用的感受元件有:金属膜片(不锈钢)、非金属膜片(橡胶或塑料)、金属波纹管(铍青铜或不
Gas regulator valve is a pneumatic controller, connect it to the gas path, without external energy supply, by the energy of the working medium itself, you can output a stable pressure. Regulator valve for gas pressure or gas flow requirements for precise control of the occasion. For example: various types of chromatography, metal gas analyzer, atomic absorption spectrometer, total organic carbon analyzer. Regulators used at home and abroad are based on the same principle of design, the main difference is that the feelings of different components. Commonly used sensing elements are: metal diaphragm (stainless steel), non-metallic diaphragm (rubber or plastic), metal bellows (beryllium bronze or not
