INTERAPP三通涡轮蝶阀结构特性：
■ 支撑性轴密封：弹性材料与酚醛背衬环的紧密结合体，有效防止由于扭曲变形导致的轴泄漏。  
■ 一体化贯穿轴：确保阀门的强度、可靠性合阀板的精确定位。 
■ O形圈：有助于防止轴泄漏。 
■ 精密准确的锥形销钉：增强防震保护，强化轴与蝶板的结合。可在现场更换。  
■ 既适用于气态介质，也适用于液态介质。 
■ 可进行双向关闭 
■ 精密准确的蝶板轮廓：防止“泡紧”关闭困难，确保程度见效扭矩，延长阀座寿命。
■ 备选维修管道终端 
INTERAPP three-way turbine butterfly valve Structural characteristics:
■ Supporting Shaft Seal: The close combination of elastic material and phenolic backing ring to effectively prevent shaft leakage due to twisting deformation.
■ Integrated through the shaft: to ensure the strength of the valve, the valve plate and reliability of the precise positioning.
■ O-ring: Helps prevent shaft leakage.
Precise and accurate tapered pins: enhanced shock protection, strengthen the combination of shaft and disc. Can be changed on site.
■ Suitable for both gaseous and liquid media.
■ can be closed in both directions
■ Precise and accurate disc contour: to prevent the "tight tight" closing difficulties, to ensure that the degree of effective torque, extended seat life.
■ Alternative maintenance pipeline terminal

INTERAPP三通涡轮蝶阀体积小、用料少、重量轻、口径越大相对其他阀更经济实惠。旋转90°即可快速启闭，操作简单。同时该阀门具有良好的流体控制特性。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时的阻力，因此通过该阀门所产生的压力降很小，当开启度在大约15°至70°之间时，又能进行灵敏的流量控制，因此大口径的流量调节，蝶阀具有较大的优势。
