Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the system of swing cleek before a kind of State of Blast Furnace, stopping valve 1, tensimeter 2, strainer 3 and oil sprayer 4 are connected successively, and its middle filtrator 3 has two, two strainer 3 parallel connections.Oil sprayer 4 is connected with electric control reversing valve 8 with the first machine control reversing valve 5-1, the second machine control reversing valve 5-2, manually operated directional valve 7 respectively through pipeline; Electric control reversing valve 8 is connected with the first Pneumatic reversal valve 6-1 and pneumatic motor 10 through pipeline successively; Electric control reversing valve 8 also is connected with the second Pneumatic reversal valve 6-2 and pneumatic motor 10 through pipeline successively; Simultaneously between the first Pneumatic reversal valve 6-1 and the second Pneumatic reversal valve 6-2 connect the pipeline of pneumatic motor 10 respectively, also be connected with shuttle valve 9, pneumatic motor 10 is connected with cylinder 12 through embracing a valve 11.Manually operated directional valve 7 also is connected with the second Pneumatic reversal valve 6-2 with the first Pneumatic reversal valve 6-1 respectively through pipeline; The second Pneumatic reversal valve 6-2 is connected with the second machine control reversing valve 5-2 through pipeline, and the first Pneumatic reversal valve 6-1 is connected with the first machine control reversing valve 5-1 through pipeline.
The principle of work of the utility model is: power gas arrives electronic reversing valve 8 and manually operated directional valve 7 through air filter 3 and oil sprayer 4; Starting east through telecontrol panel inclines; This moment, electronic reversing valve 8 right side electro-magnet got; Electronic reversing valve 8 is operated in right chamber; High pressure gas is through the left chamber of the left chamber entering pneumatic motor 10 of electronic reversing valve 8 right chambeies, the first Pneumatic reversal valve 6-1, and the band-type brake 11 that the while high pressure gas is opened pneumatic motor 10 through the left chamber of shuttle valve 9 turns clockwise pneumatic motor 10, drives swing cleek east and inclines.Starting the west through telecontrol panel inclines; This moment, electronic reversing valve 8 left side electro-magnet got; Electronic reversing valve 8 is operated in left chamber; High pressure gas is through the left chamber of the left chamber entering pneumatic motor 10 of electronic reversing valve 8 left chambeies, the second Pneumatic reversal valve 6-2, and the band-type brake 11 that the while high pressure gas is opened pneumatic motor 10 through the right chamber of shuttle valve 9 is rotated counterclockwise pneumatic motor 10, drives swing cleek west and inclines.When adopting manually operated directional valve 7, just directly manually control, principle of work is with automatically controlled identical.
In the utility model; Because the valve that uses all is mounted in below the casting house platform again near the swing cleek; Radiation temperature very high (60～70 ℃) and dust are big, and common pneumatic working temperature is selected the clearance seal electro-pneumatic reversing valve of SMC for use less than 50 ℃; Working temperature can reach 60 ℃; Employing is carried out heat insulation protection with the method that dividing plate adds insulation to the control main body again, and main valve is increased suitably to compress to purge lower the temperature and dedusting, all be to select the product of being with the high temperature protection cover for use to various power with the control cable.
In the utility model, aspect electric, requiring the button on the telecontrol panel in when design all is the crawl setting, avoids mishandle and electrical element adhesion to cause the perseveration of swing cleek, when motorized motions swing cleek, is provided with the thing limit parking of inclining.Aspect pneumatic, the first machine control reversing valve 5-1 and the second machine control reversing valve 5-2 are machine control reversing valves among Fig. 1, are installed in the both sides of swing cleek drive shaft bearing; Play the host when inclining; Pneumatic motor 10 left sides get into high pressure gas swing cleek east inclines, and when the limit was inclined in arrival east, pressing plate can be depressed the first machine control reversing valve 5-1 made the first machine control reversing valve 5-1 be operated in right chamber; High pressure gas drives the first Pneumatic reversal valve 6-1 through the right chamber of the first machine control reversing valve 5-1 and is operated in right position; Make the high pressure gas off-load in entering pneumatic motor 10 left chambeies, do not driving swing cleek continuation rotation, we can say that this protection is the most important and the most effective security measures of this cover system.
The operation of the utility model after the improvement is sensitiveer, accurately, simple, simultaneously because practical remote control control panel is operated, and operator need not look at the porthole of swing cleek straight, can reduce the injury that high temperature, dust, obnoxious flavour cause human body in a large number.Electric control reversing valve during works better adopts gap sealed structure, makes the whole valve can be high temperature resistant, has prolonged the work-ing life of valve body.
