Abstract
The invention discloses a crank burner shut-off valve used for blast furnace smelting, concluding a valve body, a valve cap, and a valve plate and driving devices. The opening and closing of the valve plate adopts crank pendulum rod structure which contains a crank, a crankshaft, a lever and a pendulum rod. The crank is fixed to the crankshaft, one end of the lever is pilot pin jointed with pendulum rod, and the other end of pendulum rod is pilot pin jointed with flashboard. The driving Devices are installed in the valve cap; electric, hydraulic, pneumatic or manual device can be used. The act of driving device spurs the crank and the lever to swinging around the crankshaft, spurring the pendulum hinged to the lever to swing and raise, spurring the valve plate hinged to the pendulum to swing and lift, the spigot opens, driving devices return, the spigot closes. There is a rotation and switching process during the open and close of valve plate, avoiding the phenomenon of block of the original valve plate wedge. The crank burner shut-off valve resolves the long-standing technical problems of blast furnace ironmaking system. The crank burner shut-off valve has the advantages of small size, small weight, reliable use, long life and can adapt to the working environment with high-temperature and powder dust of blast furnace.
Description
Technical field
The present invention relates to the crank cut-off valve that a kind of blast-furnace smelting is used.
Background technology
In the various valves of iron-smelting blast furnace hot blast stove system, except that hot blast valve, refluence damping down valve and part blast-furnace roasting valve adopt the water-cooled gate valve, during all the other are a large amount of, low temperature cutting-off valve such as cold blast valve, combustion air trip valve, gas stop valve and chimney valve etc., the general traditional product wedge-type slide valve that adopts, the slide valve good sealing effect, long service life, but shortcoming is the structure heaviness, installing space is big, the cost height.Occurred the cut-out butterfly valve afterwards, volume is little, and is in light weight, but sealing property and life-span are undesirable.A kind of crank cut-off valve has appearred again in the nineties in last century on the market, have the structure and the sealing property of gate valve, interior transmission, and the outside need not be provided with gear frame, but the interior drive mechanism of this valve has critical defect, and it is easily stuck to open moment, influences normal smelting operation.Develop that a kind of volume is little, in light weight, good seal performance, service-strong cutting-off valve be very necessary.
Summary of the invention
In order to solve the above-mentioned technical problem that the system for blast furnace ironmaking cutting-off valve exists, provide hereby that a kind of collection Gate-valve sealing performance is good, the life-span is long, and advantages such as the butterfly valve volume is little, in light weight, use reliable, moderate cost, and can adapt to the crank cut-off valve of blast furnace ironmaking high-temperature dust Working environment.
The technical solution adopted in the present invention is:
This crank cut-off valve comprises valve body, valve gap, valve plate and drive unit.The crank-rocker mechanism transmission is adopted in the keying of valve plate, crank-rocker mechanism comprises the fork of crank, crank axle, lever and lifting valve plate, crank, lever are fixedlyed connected with crank axle, and lever one end is connected with the fork hinge, and the fork the other end is connected with the flashboard axis hinge.Above-mentioned two hinged places all are equipped with the self-lubricating lining.Drive unit is arranged on the valve gap place, by drive unit driving crank swing-bar mechanism.
That drive unit can adopt is electronic, surge, pneumatic or hand gear.
Drive unit moves, and drives crank and lever and swings around crank axle, and the fork swing that drive is connected with lever hinge also promotes, and drive is swung with the hinged valve plate of fork and is raised valve opening thereupon; The drive unit backhaul, valve closes.
This oscillating rod type crank cut-off valve, scantlings of the structure is little, and is in light weight, valve plate has certain rotation moving process at the relative valve body with turn-off transient of valve opening, avoided original valve plate voussoir stuck phenomenon to take place, the valve switch reliable in action can guarantee the sealing property of trim for a long time.
This crank cut-off valve has solved the long-standing technical problem of system for blast furnace ironmaking cutting-off valve, and volume is little, in light weight, and use is reliable, the life-span is long, can adapt to blast furnace ironmaking high-temperature dust Working environment.
Description of drawings
Accompanying drawing is a front view of the present invention
Embodiment
Introduce embodiments of the invention below in conjunction with accompanying drawing.
As shown in the figure: this crank cut-off valve comprises valve body (1), valve gap (3), valve plate (2) and fluid pressure drive device (4).
The headstock gear of valve plate (2) is a crank-rocker mechanism, crank-rocker mechanism comprises crank (5), crank axle (6), lever (7) and fork (8), crank (5), lever (7) adopt key to fixedly connected with crank axle (6), lever (7) one ends are connected with fork (8) hinge, and fork (8) the other end is connected with flashboard (2) pivot hinge.Above-mentioned two hinged places all are equipped with self-lubricating lining (9).Drive unit (4) is arranged on valve gap (3) and locates.
Crank cut-off valve fluid pressure drive device (4) drives crank (5) and lever (7) transmission, thereby drives fork (8) swing and lifting, drives valve plate (2) thereupon and swings and be raised, and has realized the breakdown action of valve plate (2); The fluid pressure drive device backhaul, valve plate (2) promptly is closed.
Claims (3)
1. the crank cut-off valve used of a blast-furnace smelting, comprise valve body, valve gap, valve plate and drive unit, the crank-rocker mechanism transmission is adopted in the keying that it is characterized in that valve plate, crank-rocker mechanism comprises crank, crank axle, lever and fork, crank, lever are fixedlyed connected with crank axle, lever one end is connected with the fork hinge, and the fork the other end is connected with the flashboard axis hinge, by drive unit driving crank swing-bar mechanism.
2. crank cut-off valve according to claim 1 is characterized in that drive unit is arranged on the valve gap place, adopt electronic, surge, pneumatic or hand gear.
3. crank cut-off valve according to claim 1 is characterized in that lever and fork hinged place and fork and flashboard hinged place, all is equipped with the self-lubricating lining.
