对夹式通风 蝶阀
DUAL-CLAMP VENTING BUTTERFLY VALVE
对夹式蝶阀，普遍适用于建材、玻璃、矿山、电力、轻工、造纸等行业的通风、环保工程等管道系统中。 对管道中气体介质按不同控制信号调节流量大小和切断。
This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal.
结构特点：
Structure characteristic:
对夹式蝶阀 ，采用优质碳素钢焊接。具有重量轻、结构紧凑、流阻损失小、操作灵活、指示方位明确、维护方便、使用寿命长等优点。可任意安装，特别适合架空管道。配用电动执行器及有关配件，可实现手动、自动无干扰切换，接受仪表或计算器输出 4 ～ 20mA 信号，能微机程控、自动控制或中央集中控制，是实现自动化控制操作、调节流量的理想设备。
The valve is welded in fine carbon steel, having the features of light weight, compact structure, endurance, little in the lost of flow resistance, definite direction, easy to maintenance and long life. It can be installed at any angle, especially suitable for aerial piping. The valve is used with electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, microcomputer long-range control, automatic control or center concentrating control. It receives 4 ～ 20mA signal output by meter or computer . It is the ideal equipment of realizing operation of automatic control and adjusting flow.
