Description
Technical field
The present invention relates to a kind of double eccentric flange electrodynamic type butterfly valves peculiar to vessel.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member is disk, and a kind of valve of open and close is reached around valve shaft rotation.Valve can be used for control air,
The flowing of the various types fluids such as water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium.
Cut-out and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axis of its own in valve body
Line rotates, to achieve the purpose that keying or adjusting.Double eccentric flange electrodynamic type butterfly valves peculiar to vessel are one kind of butterfly valve, this at present
For butterfly valve for easily being damaged by external impacts when hull pipeline, valve body and valve rod are most easily damaged position.
