In order to solve the above-mentioned technical problem the present invention, adopts the following technical scheme that：
A kind of high-temperature water cooling flue butterfly valve, including executing agency, valve body, valve seat, valve rod and valve plate, open up in the valve body
There is the first cooling duct, offer the import of coolant first, first outlet on valve body, the first cooling duct and the first import, the
One outlet；The second cooling duct is installed with the valve rod, the import of coolant second is offered on valve rod, second is gone out
Mouthful, the second cooling duct connects with the second import, second outlet.
Butterfly valve body is arranged to hollow by setting, opens up the first cooling duct, carries out cooling water circulation, is realized quick
Reduce valve body temperature.The second cooling duct is opened up by being arranged in valve rod, carries out cooling water circulation, realizes quick reduction valve rod
Temperature, butterfly valve resistance to elevated temperatures is improved, and with water consumption is few, heatproof is high, service life is long, operation is easy to maintenance, rotation is clever
The features such as living.
The high-temperature water cooling flue butterfly valve can support the use with various YEs, realize far distance controlled and automatic tune
Section and cut-out, are widely used in the superhigh temperature gas pipeline of the industries such as metallurgy, chemical industry, building materials, power station, are adjusted as rate-of flow
Section and cut-out use.
Further improve, first cooling duct is circumferentially disposed in valve flange, the first cooling duct of increase length
Degree, improve cooling effect.
Further improve, the 3rd cooling duct is provided with the valve plate, the 3rd cooling duct connects with the second cooling duct
It is logical.By setting the 3rd cooling duct in valve plate, valve plate temperature is reduced, prevents valve plate from being deformed because of high temperature, passes through cooling water
Circulation is indeformable to the continual cooling of valve, guarantee valve high temperature resistant.
Further improve, the 3rd cooling duct is in S shapes, increases by the 3rd cooling duct length, improves cooling effect.
Further improve, second import, second outlet open up close to valve body.
Further to improve, the aperture of first import is less than first outlet, and the aperture of the second import is less than second outlet,
It is easy to coolant quickly to flow, improves cooling effect.
Further improve, the valve body is connected by connecting rod with executing agency to be connected, close to executing agency on valve rod
One end is provided with fin, and in order to ensure the intensity of valve rod, the length of the second cooling duct can not possibly be opened along whole shaft length
If by setting fin, the heat that sheds in time on valve rod prevents executing agency from being damaged because of high temperature.
Compared with prior art, the beneficial effects of the invention are as follows：
Butterfly valve body is arranged to hollow by setting, opens up the first cooling duct, carries out cooling water circulation, is realized quick
Reduce valve body temperature.The second cooling duct is opened up by being arranged in valve rod, carries out cooling water circulation, realizes quick reduction valve rod
Temperature, butterfly valve resistance to elevated temperatures is improved, and with water consumption is few, heatproof is high, service life is long, operation is easy to maintenance, rotation is clever
The features such as living.
