Abstract
A kind of can be under 900～1350 ℃ of high-temperature hot air ambient conditions the air-cooled hot blast valve of works better.This air-cooled hot blast valve respectively bores a circle wind hole on the sealing contact surface of valve body, valve plate, make cold wind constantly flow into the hot-blast pipe line at hot blast valve place through the wind hole, reaches the cooling purpose.System opens cold wind shunt conduit valve when moving, cold wind enters valve body cold wind cavity and valve plate cold wind cavity through valve body cold wind blast pipe, valve plate cold wind blast pipe respectively, enters hot air duct through the gap of valve body valve plate noncontact trim one side again through valve body wind hole, valve plate wind hole respectively.Cold wind has reduced the temperature of valve body valve plate in flow process, self be heated as the essential high-temperature hot air of next procedure simultaneously, and be fully used.
Description
Affiliated technical field
The utility model relates to a kind of hot blast valve, and hot blast valve is the cut-out equipment of 900 ℃ of iron-smelting blast furnaces and above high-temperature hot air, is used for the cut-out and the conducting of high-temperature hot air pipeline.
Background technology
At present, known hot blast valve for works better under 900～1350 ℃ of high-temperature hot air ambient conditions, in valve gap, valve body, the logical recirculated cooling water in valve plate temperatures involved position, reduces the temperature of Valve Steel product.The use of water coolant, the heat energy discharging that not only expends great amount of water resources, a large amount of no utility value is aerial, but also will drop into the circulation in order to dry in the air water and water coolant of a large amount of places, buildings and electric power.The iron and steel enterprise of the northern area of China in the production process, because of the minibreak of producing causes water coolant to freeze often, influences ordinary production in the winter time in pipeline.
Summary of the invention
In order to eliminate hot blast valve in use to the demand of water resources, place, buildings, reduce power consumption, reduce the heat energy discharging, the utility model provides a kind of air-cooled hot blast valve.This hot blast valve is under the situation that does not make water, can make hot blast valve works better under 900～1350 ℃ of high-temperature hot air ambient conditions, and be used for being heated as the essential high-temperature hot air of next procedure in process to the steelwork cooling to the cold wind of steelwork cooling.The cold wind source need not increase equipment input, and the cold wind stage before high-temperature hot air is heated distributes the sub-fraction of not influence system operation, both can satisfy the cooling needs of air-cooled hot blast valve.
The technical scheme that its technical problem that solves the utility model adopts is: respectively bore a circle wind hole on the sealing contact surface of valve body, valve plate, make cold wind constantly flow into the hot-blast pipe line at hot blast valve place through the wind hole, reach the cooling purpose.Temperature is imported respectively in the cold wind cavity of the valve plate of hot blast valve and valve inner through valve plate cold wind blast pipe and valve body cold wind blast pipe at the freezing air below 200 ℃, and the cold wind in the cold wind cavity constantly flows into the hot-blast pipe line at hot blast valve place through being distributed in the circle of two on sealing contact surface wind hole.Valve is in opened condition, and hot-blast pipe line is switched on, and valve plate is in the high-end trim in the valve gap cavity, by the effusive cold wind in valve plate wind hole valve plate and valve gap is cooled simultaneously; Near sealing contact surface, form the low temperature subenvironment by the effusive cold wind in valve body wind hole, reduced the temperature of the steelwork of no lagging material protection.Valve in off position, valve plate is in the low-end trim in the valve cavity, the high-temperature hot air that pressure is high is pushed valve plate to low-temp low-pressure one side, and valve plate, valve seal contact surface are fitted, hot-blast pipe line is blocked.With the high-temperature hot air hot blast valve that constantly blows off, between hot blast valve and high-temperature hot air, form a cold wind low temperature vent plug by valve plate, the effusive cold wind in valve body wind hole.In process of production, because the pressure loss in piping of cold wind process is less than hot-blast pipe line, cold wind can continue realization through the wind orifice flow to the process of hot-blast pipe line.
The beneficial effects of the utility model are to guarantee hot blast valve works better under 900～1350 ℃ of high-temperature hot air ambient conditions, and be used for being heated as the essential high-temperature hot air of next procedure to the cold wind of steelwork cooling in the process to the steelwork cooling.Compare with present known water-cooled hot blast valve and to have eliminated hot blast valve, reduce power consumption, reduce the heat energy discharging in use to the demand of water resources, place, buildings.User's investment and working cost have been reduced.
