手动翻板式三杆蝶阀引进技术，广泛适用于建材、玻璃、矿山、电力、轻工、造纸等行业的能源输送管道的煤气、天然气、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 transporting coal gas, natural gas, venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. The technique is introduced from foreign Company. It can change the flow and cut off gas medium in the pipe by the different control signal.
结构特点：
Structure characteristic:
手动翻板式三杆蝶阀具有结构、耐磨损、流阻损失小、密封性强、自锁性可靠、操作灵活、指示方位明确、维护方便、密封面无磨损、使用寿命长等优点，尤其传动轴部分采用外部密封，易调整、易更换无需停机，从而有效地杜绝外漏。采用多种密封形式能适应不同的介质，特别适用于调节切断和要求快速自保的场合。配用蜗轮传动装置，可实现启闭操作，是调节流量的理想设备。
The valve has the features of compact structure, endurance, little in the lost of flow resistance, good seal, reliable self-locking, flexible operation, definite direction, easy to maintenance and long life. The seal of driving shaft is out seal, which is easy to be adjusted and changed without stopping, so the out leakage is avoided effectively. All kinds of seal type can suit different medium. It is especially suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with worm gear driving device to form a complete set to realize open-close operation. It is the ideal equipment of adjusting flow.
