Description
Technical field
The utility model relates to hot blast valve or the guiding valve that is used for the smelting iron blast furnace, is specially a kind of high temperature heat-resistant air valve that is used for hotblast stove.
Background technology
High wind-warm syndrome is the important technology feature of modern blast furnace, and improving wind-warm syndrome is the major technique measure that increases injecting coal quantity, reduces coke ratio, reduces production costs.Hotblast stove is the equipment for blast furnace heating air blast, is the indispensable important component part of modern blast furnace.Hot-blast valve between hotblast stove wind mixed chamber and the hot air duct is the shut-off device that hot air furnace hot air leads to blast furnace, this position is the weak part that hotblast stove is connected with hot air duct, is overhauling with overhaul and hotblast stove just must be with this valve closes when keeping production status to blast-furnace body or to pipeline.Hot-blast valve as shut-off device can only be temporary transient disconnection, can not be through long high temperature, hot blast valve cuts off the back sealing effectiveness of coal gas also be can not get ensureing simultaneously.Enclosure method to this position was manually to carry out hot plugging earlier in the past, built one refractory brickwork then in wind mixed chamber's short tube by laying bricks or stones, carried out coal gas and pyritous sealing by this form.Yet this method is in extreme danger on safety, does not also satisfy on the time of shutoff simultaneously and has also come fast more maintenance and overhaul paces, and this long-time and adventurous constructional method is also bad to coal gas and pyritous sealing effect that hotblast stove produces.
Summary of the invention
In order to overcome the defective of prior art, provide a kind of when hotblast stove overhauls the good and hot air furnace hot air occluding device safely and reliably of sealing effect, the utility model discloses a kind of high temperature heat-resistant air valve that is used for hotblast stove.
The utility model reaches goal of the invention in the following way:
A kind of high temperature heat-resistant air valve that is used for hotblast stove, comprise base, shell, upper cover plate, lower cover, refractory layer, thermofin, strengthen gusset, water-cooled tube, rapid-acting coupling, flange and hanger, it is characterized in that: shell places on the base, sealing with upper cover plate and lower cover respectively up and down of shell, enclosure one side is lined with refractory layer and thermofin successively, the fixing gusset of strengthening of enclosure opposite side, the two ends of strengthening gusset successively and upper cover plate, lower cover connects, place water-cooled tube between thermofin and the reinforcement gusset, the two ends of water-cooled tube are separately fixed on upper cover plate and the lower cover and also pass on the slave plate face, the two ends of water-cooled tube all are connected with rapid-acting coupling, all be connected with flange on upper cover plate and the lower cover, a hanger is fixed in the upper cover plate centre.
The described high temperature heat-resistant air valve that is used for hotblast stove, it is characterized in that: refractory layer is selected refractory fireclay block for use, and thermofin is selected the clay brick of surface spraying heat resisting coating for use.
The described high temperature heat-resistant air valve that is used for hotblast stove is characterized in that: water-cooled tube is volution or serpentine.
When the utility model uses, by hanger it is winched between hot blast furnace side and the hot blast person in charge side, be connected and fixed by flange respectively, in water-cooled tube, feed water coolant, can finish and replace the hot air furnace hot air valve with weight handling equipment.The utility model has solved the problem of dangerous big, high temperature of hot air duct hot plugging construction and coal gas sealing effect difference, and the beneficial effects of the utility model are: draw materials easily, and easy to make, safe and reliable.
