产品特点:                                                          
      本蝶阀主要由阀体、转轴、阀板、阀座及驱动机构(手柄、蜗轮蜗杆、气动装置或电动装置)等组成,靠驱动机构带动转轴及阀板旋转以实现启闭和控制流量的目的。其特点如下:
      结构简单、小巧轻便,运输、安装、拆卸容易;90°启闭,开关迅速。操作扭矩小,省力轻巧;密封性能好,使用寿命长,可达到零泄漏;选择不同的零部件材质,可适用于多种介质;流量特性近似于直线,调节性能好。       
      A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and it can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc  that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation , installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
