Abstract
The utility model relates to a water-blast composite cooling hot blast valve that can be normally operated under the condition of heat air medium with high temperature of 900 DEG C-1350 DEG C. The water-blast composite cooling hot blast valve is provided with a cold blast inletting pipe both at the lower part of the valve and the upper part of a valve cover, with a prerequisite of remaining water-cooling hot blast valve structure, so that the cold blast flows constantly into a hot blast pipe in which the hot blast valve is arranged through a blast inletting pipe, thereby reducing the temperature. A cold blast streaming pipe valve is opened when the system is working, and the cold blast enters the inner cavity of the water-blast composite cooling hot blast valve through the cold blast inletting pipe of the valve and the cold blast inletting pipe of the valve cover, and then flows into the hot blast pipe from the upper part and the lower part. While the cold blast is heated to become high temperature hot air, the temperature of the valve body, the valve plate and the valve cover is lowered when the cold blast flows, thereby making full use of the cold blast.
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 body, the logical recirculated cooling water in valve plate temperatures involved position, reduces the temperature of Valve Steel product.For the temperature that reduces steelwork not only expends great amount of water resources, a large amount of heat energy discharges in the air, but also to drop into the circulation of a large amount of places, buildings and electric power in order to dry in the air water and water coolant.Hot blast valve cut off and the conversion of conducting working order in produce the temperature difference of several Baidu, cold and heat succeed each other and cause metal fever fatigue, reduction hot blast valve work-ing life.
Summary of the invention
In order to reduce 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 geomantic omen compound cooling heat air-valve.This hot blast valve can not only be under 900～1350 ℃ of high-temperature hot air ambient conditions works better, and all significantly reductions of the heat energy of water coolant that is consumed and discharging, be used for being heated as available high-temperature hot air 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 needs to cold wind of the compound cooling heat air-valve in geomantic omen.
The technical scheme that its technical problem that solves the utility model adopts is: on water-cooled hot air valve body, valve gap intake opening is set respectively, the cold wind blast pipe is installed, make cold wind constantly flow into the hot-blast pipe line at hot blast valve place through the cold wind blast pipe, reach the cooling purpose.Temperature imports geomantic omen compound cooling heat air-valve upper cavity at the cold wind below 200 ℃ through valve gap cold wind blast pipe, and the continuous inflow of cold wind has reduced the local temperature of upper cavity; The valve body cold wind blast pipe of cold wind through being located at valve body lower portion constantly flows into valve body lower portion, reduces the local temperature of the dangerous position of valve body lower portion.
The beneficial effects of the utility model are guarantee the compound cooling heat air-valve in geomantic omen works better under 900～1350 ℃ of high-temperature hot air ambient conditions, and the heat energy of water coolant that is used to lower the temperature and discharging to be reduced effectively.Air-cooled district local ambient temperature reduces, and has dwindled the temperature difference that the compound cooling heat air-valve in geomantic omen produces in cut-out and the conversion of conducting working order, has improved work-ing life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front elevation of embodiment, and Fig. 2 is the side elevational view of embodiment, and Fig. 3 is the A--A sectional view of Fig. 1.
1. valve body cold wind blast pipes among the figure, 2. valve body, 3. valve plate, 4. valve body cooling water outlet, 5. valve body cooling water intake, 6. valve gap, 7. valve gap cold wind blast pipe, 8. filler, 9. gland, 10. valve plate water coolant intake-outlet.
Embodiment
The compound cooling heat air-valve in geomantic omen is installed in flange connection on the hot air duct of ironmaking system, top mounted valve headstock gear.In the accompanying drawing, valve body cold wind blast pipe (1), valve gap cold wind blast pipe (7) are connected on the cold wind shunt conduit of ironmaking system.System opens cold wind shunt conduit valve during operation, and cold wind enters valve body lower portion cavity and valve gap upper cavity through valve body cold wind blast pipe (1), valve plate cold wind blast pipe (7) respectively, flows to hot air duct from bottom and top respectively again.Cold wind has stoped heat exchange between the compound cooling heat air-valve of high-temperature hot air and geomantic omen, has taken away heat in flow process, reduced the temperature of valve body (2) valve plate (3) valve gap (6), self is heated as high-temperature hot air simultaneously, and is fully used.
Claims (2)
1. compound cooling heat air-valve in geomantic omen, keeping on the water-cooled hot blast valve architecture basics, be respectively equipped with the cold wind blast pipe and communicate on valve body lower portion, valve gap top, it is characterized in that: be respectively equipped with the cold wind blast pipe on water-cooled hot air valve body bottom, valve gap top with internal cavities.
2. the compound cooling heat air-valve in geomantic omen according to claim 1 is characterized in that: the cold wind blast pipe that valve body lower portion, valve gap top are respectively equipped with communicates with the internal cavities of this valve.
