Description
Technical field
The utility model relates to safety of chemical production apparatus field more particularly to a kind of high-temperature flue gas control valves.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.
Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a disc
Butterfly plate, in valve body around its own axis rotate, to achieve the purpose that opening and closing or adjusting.
The valve plate edge of butterfly valve needs and valve body contact, however valve plate itself has a certain thickness, in valve body rotation process
It is inevitable to generate certain friction with valve body inside, therefore valve plate thickness cannot be blocked up, or valve plate edge is processed into spherical arc,
The former reduces valve plate intensity, and especially when being applied to high-temperature flue gas control, valve plate easily generates deformation, and the latter then makes to process
It is more difficult.
Utility model content
The purpose of the utility model is to provide a kind of high-temperature flue gas control valves, can effectively reduce between valve plate and valve body and rub,
Have no effect on valve body self-strength.
To achieve the goals above, the utility model provides the following technical solutions:
A kind of high-temperature flue gas control valve, including valve body, valve plate, connecting shaft and control device, the valve plate are set to valve body
It is interior, it is rotatablely connected with valve body, the connecting shaft and valve body are rotatablely connected, and one end of the connecting shaft is fixedly connected with valve plate, other end position
It is connect outside valve body, and with control device, arc groove is arranged in the valve plate side, and the arc groove is only arranged at valve plate side
One side, and the arc groove at left and right sides of valve plate along connecting shaft center be symmetrical arranged.Arc groove obtains the thickness at valve plate edge
It reduces, reduces the area of edge and valve body contact, while contact surface is symmetrical along connecting shaft center, so that valve plate is along fixation side
Make hardly to generate unnecessary friction with valve body to opening or closing.
Preferably, the thickness of the valve plate side is inwardly gradually increased by most edge.This design can be further reduced valve
The friction of edges of boards edge and valve body.
Preferably, the connecting shaft is located at the setting of the part outside valve body spiral radiator.One side of spiral radiator
Face can play the effect of heat dissipation, on the other hand can also auxiliary transmission torque, keep the rigidity of connecting shaft more preferable.
Preferably, the valve plate surface setting multiple directions deflector vertical with connecting shaft, deflector are arc-shaped.It leads
Flowing plate can play the role of being oriented to flue gas and increasing valve plate intensity.
Preferably, blowing device is set in the valve body, and the blowing device is set to connecting shaft and valve body junction is attached
Closely, blowing device includes venthole, and connecting shaft and valve body junction are directed toward in the venthole direction.Blowing device can be used for blowing out
The solid particle for remaining in connecting shaft Yu valve body junction prevents it from entering junction and damages to equipment.
Preferably, the control device includes handwheel and turbine and worm mechanism, the handwheel by turbine and worm mechanism with
Connect axis connection.Turbine and worm mechanism can play the role of amplifying torque, convenient manually to control valve plate.
The utility model has the following beneficial effects:
1. the friction of valve plate edge and valve body minimizes when valve plate directional rotating；
2. the rigidity that spiral radiator can play heat dissipation effect and connecting shaft.
