Technical field
This utility model is related to a kind of coke-oven dust removing system, the fast shut-off dress in particularly a kind of coke-oven dust removing system
Put.
Background technology
In coke oven dust operating process, when burst power-off in the case of, blower fan system can because motor time-lag action,
The inertia rotary action of draught fan impeller, can't stop operating at once, and system can keep a certain amount of negative pressure.But now, blower fan
The suction that system can be provided has been not sufficient to ensure that flue gas is filtered normal through dust pelletizing system.At this time come in pipeline
Flue gas substantial amounts of can be poured in cleaner, and after blower fan is finally stopped work, this partial fume can be cumulative, when flue gas gathers
Collect finite concentration, device interior pressure will explode more than design limit.Equipment is caused partly or wholly to destroy even
Bring personnel casualty accidentses！Therefore, in system design, from the security standpoint of whole coke-oven dust removing system, remove entering
One quick cutting device is set on the pipeline before dirt equipment, prevents flue gas from entering cleaner in the state of accident, be very
It is necessary.
This valve is in normally open under dust pelletizing system normal operation, and when unexpected powering-off state is run into, valve stands
Close, cut off the passage that flue gas enters cleaner, it is to avoid equipment occurs the danger of blast.
Because quick cutting device is related to the safety of system or even the person, it is desirable to reliable working performance, it is ensured that very
Due effect can be played under state.
The content of the invention
It is an object of the invention to provide one kind is than existing reliable working performance, response time is fast, the good coke oven of safety
Quick cutting device in dust pelletizing system.
The object of the present invention is achieved like this, the quick cutting device in a kind of coke-oven dust removing system, it is characterized in that：Extremely
Include less：Electromagnetic valve, cylinder, butterfly valve and source of the gas, electromagnetic valve and cylinder composition cylinder solenoid valve component, electromagnetic valve component and butterfly valve
Axle connects；Described source of the gas is connected with the gas access mouth of pipe of the two-position-five-way solenoid valve of electromagnetic valve component；Two-position five-way electromagnetism
Gas access and gas outlet of the valve by two-way pipe fitting with cylinder；The cylinder body of cylinder is connected with butterfly valve drive rod；Butterfly valve
With the pipeline communication that flue gas enters dust pelletizing system equipment.
Described butterfly valve includes valve plate and valve body, and valve plate connects valve body, valve plate pivoting in valve body by connecting shaft.
Described electromagnetic valve is two-position-five-way solenoid valve.
The utility model has the advantages that：By controlling two-position-five-way solenoid valve, source of the gas pair is controlled by two-position-five-way solenoid valve
Cylinder action, the piston rod for making cylinder is moved forward and backward, and the valve plate for opening and closing butterfly valve is rotated, and valve plate is turned at 0 degree or 90 degree
It is dynamic, realize that flue gas is completely severed or is fully turned on into the pipeline of dust pelletizing system equipment, Pneumatic butterfly valve has compact conformation,
Staring torque is little, opens and closes lightly, and switch is rapid, is capable of achieving flue gas circulation under normal condition；Close in time under accident condition.

Fig. 3 is two-position-five-way solenoid valve structural representation.
In figure, 1, two-position-five-way solenoid valve；2nd, cylinder；3rd, butterfly valve；4th, source of the gas；5th, valve plate；6th, valve plate；7th, flue gas is entered and removed
The pipeline of dirt system equipment；8th, connecting shaft；9th, cylinder solenoid valve component.
Specific embodiment
As depicted in figs. 1 and 2, the quick cutting device in a kind of coke-oven dust removing system, at least including electromagnetic valve 1, cylinder
2nd, butterfly valve 3 and source of the gas 4, by electromagnetic valve 1 and cylinder 2 cylinder solenoid valve component 9 is constituted, and electromagnetic valve component 9 is connected with the axle of butterfly valve 3.
Source of the gas 4 is connected with the gas access mouth of pipe of the two-position-five-way solenoid valve 1 of electromagnetic valve component 9；Two-position-five-way solenoid valve 1
By the gas access and gas outlet of two-way pipe fitting and cylinder 2；The cylinder body of cylinder 2 is connected with the drive rod of butterfly valve 3；Butterfly valve
3 pipelines 7 for entering dust pelletizing system equipment with flue gas are connected.
As shown in Fig. 2 butterfly valve 3 includes valve plate 6 and valve body 5, valve plate 6 connects valve body 5 by connecting shaft 8, and valve plate 6 is in valve body
Pivoting in 5.The pipeline 7 that the gas inlet-outlet of butterfly valve 3 enters dust pelletizing system equipment with flue gas is connected.
As shown in figure 3, electromagnetic valve 1 is two-position-five-way solenoid valve, two-position-five-way solenoid valve includes air inlet 301, and first goes out
QI KOU 302, the second gas outlet 304, first row QI KOU 303, second exhaust port 305.When coil 306 is powered, valve element 307 is in electricity
Under magneticaction, the channel conductive of 301 and second gas outlet of air inlet 304；Gas is through the gas outlet of air inlet 301 to the second 304
