I. Overview of Bellows Cage Double Seat Control Valve
是一种压力平衡式的调节阀，阀体结构紧凑，流体通道呈 S 流线型，压降损失小，流量大、可调范围广。 The bellows cage double seated regulating valve is a pressure-balanced regulating valve. The valve body has a compact structure, the fluid passage is S streamlined, the pressure loss is small, the flow rate is large, and the adjustable range is wide. The upper valve cover adopts the corrugated tube seal structure, which can completely eliminate the possibility of the process medium leaking out from the valve rod movement gap, which is one of the salient features of the corrugated tube seal valve. Due to the deformability and outstanding aging resistance of the bellows element itself, this regulating valve completely overcomes the weaknesses such as 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 pneumatic regulating valve is equipped with a multi-spring type diaphragm actuator, which has a compact structure and a large output force.
Second, the main performance of the bellows cage double seat regulating valve
