1、蝶阀具有结构简单、体积小、重量轻、材料耗用省,安装尺寸小,开关迅速、90°往复回转,驱动力矩小等特点,用于截断、接通、调节管路中的介质,具有良好的流体控制特性和关闭密封性能。
2、蝶阀可以运送泥浆,在管道口积存液体zui少。 低压下,可以实现良好的密封。 调节性能好。
3、蝶板的流线形设计,使流体阻力损失小,可谓是一种节能型产品。
4、阀杆为通杆结构,经过调质处理,有良好的综合力学性能和抗腐蚀性,抗擦伤性。蝶阀启闭时阀杆只作旋转运动而不作升降运行,阀杆的填料不易破坏,密封可靠。与蝶板锥销固定,外伸端为防冲出型设计,以免在阀杆与蝶板连接处意外断裂时阀杆崩出。
5、 连接方式有法兰连接、对夹连接、对焊连接及凸耳对夹连接。
