I. Overview of small-bore single-seat regulating valve with bellows seal

,上阀盖采用波管纹密封结构,可彻底消除工艺介质从阀杆运动间隙向外泄漏的可能性,这是波纹管密封阀的显著特点之一,由于波纹管元件本身变形性和卓著的抗老化性,这种 电动单座调节阀 完全克服了填料密封阀通常存在的填料老化和温差敏感等弱点。 Bellows sealed small-diameter single-seat regulating valve . The upper bonnet adopts a corrugated seal structure, which can completely eliminate the possibility of process media leaking outward from the valve stem movement gap. This is one of the salient features of the bellows sealed valve. The bellows element itself is deformable and outstandingly resistant to aging. This electric single-seat regulating valve completely overcomes the weaknesses of aging and temperature difference sensitivity of packing seal valves. Secondly, the double sealed structure of bellows and packing is adopted for better safety and reliability. Therefore, it is widely used in automatic control systems for rare special media such as highly toxic, highly corrosive and radioactive. 配用多弹簧式薄膜执行机构,其结构紧凑,输出力大。 The electric regulating valve is equipped with a multi-spring type diaphragm actuator, which has a compact structure and a large output force.
