本专利技术是一种水力自闭双平板活门蝴蝶阀,它属于输液阀机械工程领域。该阀不需要单独设立一套压力油源设备,并能够保护橡胶密封件不受损坏,有效地防止漏水。在发电机组紧急事故时,操作动力源失灵,可依靠水力。蝴蝶阀能够自行关闭活门,保护发电站和机组的安全。该阀装配后,活门的转轴中心对阀体中心或活门中心构成双偏心结构。该阀橡胶密封件装配在阀体侧中心线右侧,供水力发电站、火力发电站及水泵站的输水管道中使
The patented technology is a hydraulic self-closing double-plate butterfly valve flap valve, which belongs to the field of infusion valve mechanical engineering. The valve does not require a separate set of pressure oil source equipment, and to protect the rubber seals from damage, effectively prevent water leakage. In the generator set emergency, the operation of the power failure, you can rely on water. Butterfly valve to close the valve itself, to protect the safety of power plants and units. The valve assembly, the valve shaft center of the valve body or valve center double eccentric structure. The valve rubber seal mounted on the right side of the centerline of the valve body, for water power stations, thermal power stations and pumping stations in the water pipeline
