Description
Technical field
The present invention relates to a kind of centre type pneumatic 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.Centre type pneumatic type butterfly valve peculiar to vessel is a kind of butterfly valve, at present failure master
It to be the damage of cylinder.Inspector can not understand the inclination angle of internal valve plate by appearance to this butterfly valve in use simultaneously
Degree, cannot also be visually known the job state of valve plate.
Invention content
The present invention is mainly the technical problem solved present in the prior art, to provide a kind of centre type pneumatic type peculiar to vessel
