一、进口气动小流量调节阀概述

进口气动小流量调节阀（美国威盾VTON），Pneumatic small flow control valve，也叫进口气动小口径调节阀，由气动薄膜执行器及微小流量调节阀阀体组成，多弹簧执行机构高度低、重量轻、装备简便。气动小流量调节阀具有体积小、重量轻、性能高、用于微小流量的精确控制等特点。调节不干净介质时，应针对其节流间隙小的问题，注意预防堵卡现象的发生。气动小流量调节阀特别适用于液体、蒸汽等介质的主流量调节场合。

Pneumatic small flow control valve (VTON), also known as imported pneumatic small diameter control valve, is composed of a pneumatic diaphragm actuator and a small flow control valve body. The multi spring actuator has low height, light weight, and is easy to equip. Pneumatic small flow control valves have the characteristics of small volume, light weight, high performance, and precise control for small flow rates. When adjusting unclean media, attention should be paid to the issue of small throttling clearance and prevention of blockage. Pneumatic small flow control valves are particularly suitable for regulating the mainstream flow of media such as liquids and steam.

进口气动小流量调节阀口径DN1-DN15，是一种控制微小流量的特殊调节阀，广泛应用于实验室的实验装置上，或批量生产的工业装置上，控制化学物品，燃料，香料或其它添加剂。调节阀流量系数0.001~0.63，流量系数从0.16~0.63的阀，只用一个相同阀座，阀座还可以倒过来使用。更换阀芯和阀座就可以改变流量系数。调节阀带上定位装置，利用反馈杠杆，可使阀的额定行程缩小40%或扩大20%。阀内组件不用螺纹连接，拆卸方便。

The pneumatic small flow control valve has a diameter of DN1-DN15 and is a special control valve for controlling small flow. It is widely used in laboratory experimental devices or industrial devices for mass production to control chemicals, fuels, spices, or other additives. A valve with a flow coefficient ranging from 0.001 to 0.63 and a flow coefficient ranging from 0.16 to 0.63 only uses the same valve seat, which can also be used upside down. Replacing the valve core and valve seat can change the flow coefficient. The regulating valve is equipped with a positioning device, and using a feedback lever, the rated stroke of the valve can be reduced by 40% or increased by 20%. The valve components do not require threaded connections, making disassembly convenient.
