Abstract
The utility model provides a control device for an emergency water electromagnetic valve of a vacuum furnace. The control device comprises the electromagnetic valve, a charger, a storage battery, a main contactor, a hand operated switch, a red indicating lamp, a green indicating lamp and a fuse. The main contactor is directly connected into a power grid, a first normally closed contact and the red indicating lamp are in series connection in the power grid, and a second normally closed contact and the charger are in series connection in the power grid. In an electromagnetic valve circuit, the storage battery is connected with the charger, a first normally open contact is connected with the green indicating lamp in series and is connected with the electromagnetic valve in parallel, and a second normally open contact is connected with the hand operated switch and the storage battery. When the power grid is in normal operation, the storage batter is in a recharged state; when the power grid is cut off suddenly, the electromagnetic valve is switched into an operating state through the control loop, so that emergency water is led into the vacuum furnace after the electromagnetic valve is switched on. After the power grid recovers to normal state, the electromagnetic valve is switched into a stop state through the control loop. By the aid of the control device, emergency water flows into the vacuum furnace quickly so as to cool the vacuum furnace when the power grid is in failure.
Description
Technical field
The utility model belongs to the control circuit field, is specially a kind of control gear that is used for the emergent water solenoid valve of vacuum furnace.
Background technique
At present, mostly the solenoid valve of the emergent water of vacuum furnace in use directly is overlapped on the coil of solenoid valve on the factory building general power, when electrical network just often, electromagnetic valve coil gets electric, and solenoid valve is in the prevention working state always, thereby stops emergent water to introduce vacuum furnace; When electrical network breaks down suddenly, the electromagnetic valve coil dead electricity, solenoid valve begins to connect, and makes emergent water insert vacuum furnace, realizes the effect of vacuum furnace cooling under the grid failure state.
There are two problems in solenoid valve under this usage mode:
1. electromagnetic valve coil is in charged working condition for a long time, and coil is easy to damage, and must periodic maintenance change solenoid valve;
2. the solenoid valve operating mode under this working method is comparatively special, and promptly solenoid valve when work pipeline is blocked, but not during working condition, pipeline is switched on, so buying difficulty comparatively.
The model utility content
In order to address the above problem, the utility model proposes a kind of control gear that is used for the emergent water solenoid valve of vacuum furnace, technological scheme is as follows:
Described a kind of control gear that is used for the emergent water solenoid valve of vacuum furnace is characterized in that: comprise solenoid valve, charger, storage battery, main contactor, manual control switch, red green tutorial light and fus; Main contactor directly is connected in the electrical network, and first normally-closed contact and red tutorial light series connection are in electrical network, and second normally-closed contact and charger series connection are in electrical network; In electromagnetic valve circuit, storage battery is connected with charger, and first normally opened contact is connected with green tutorial light, and in parallel with solenoid valve, is connected with storage battery with the manual control switch by second normally opened contact again.
Described a kind of preferred version that is used for the control gear of the emergent water solenoid valve of vacuum furnace, it is characterized in that: also include the backup contactor, the backup contactor directly is connected in the electrical network, and the normally-closed contact of backup contactor control and normally opened contact are in parallel with first normally-closed contact, second normally-closed contact, first normally opened contact and second normally opened contact of main contactor control respectively.
The utility model at electrical network just often, storage battery is in automatic charged state, and when electrical network cut off the power supply suddenly, control loop automatically switched to the solenoid valve working condition, solenoid valve is connected emergent water and is introduced vacuum furnace; After power system restoration was normal, control loop automatically switched to the solenoid valve state that quits work again.By the electromagnetic valve circuit is improved, the emergent water of vacuum furnace flows into rapidly in the stove when realizing electric network fault, plays the cooling purpose.Solenoid valve after the improvement is the common standard type, is easy to buying, the life-span is longer, safe and reliable to operation, reduces and safeguards.

Embodiment
Below in conjunction with specific embodiment the utility model is described:
With reference to accompanying drawing 1, present embodiment includes solenoid valve 1, charger 3, storage battery 2, main contactor KA1, manual control switch 4, red green tutorial light and fus FU.
Main contactor KA1 directly is connected in the electrical network, the first normally-closed contact KA11 be connected in the electrical network after red tutorial light L1 connects, the second normally-closed contact KA12 be connected in the electrical network after charger 3 is connected; In electromagnetic valve circuit, storage battery 2 is connected with charger 3, and the first normally opened contact KA13 connects with green tutorial light L2, and in parallel with solenoid valve 1, is connected with storage battery 2 with manual control switch 4 by the second normally opened contact KA14 again.Simultaneously in order to prevent that main contactor KA1 from breaking down, not having behind grid cut-off can be with the normally closed switch closure, also be provided with backup contactor KA2 in the utility model, and back up normally-closed contact KA21, the second backup normally-closed contact KA22, first by first of backup contactor KA2 control and back up the normally opened contact KA23 and the second backup normally opened contact KA24, these backup contacts are connected in parallel with the contact that corresponding main contactor is controlled respectively.
In the present embodiment, each number of element types is: charger CDZ-B, storage battery SW2440, manual stop switch HS10-40/2, relay J DZ-22, fus RT9-20/6A.Charger 3 and storage battery 2 are piths between solenoid valve 1 and the factory building power supply in the present embodiment, the input end of charger 3 is connected on the total electricity of factory building by the second normally-closed contact KA12 and the second backup normally-closed contact KA22, output terminal connects storage battery 2, storage battery 2 backs up normally opened contact KA24 by manual control switch 4 and the second normally opened contact KA14 and second again and is connected on the solenoid valve 1, has realized the purpose that the The whole control device automaticallyes switch.
Storage battery 2 just often is in charged state by charger 3 at electrical network, and solenoid valve 1 is in the state of quitting work, and stops emergent water to flow into vacuum furnace, connects all normally-closed contact closures of contactor on the line, and normally opened contact disconnects, and red led point L1 is bright.When factory building cuts off the power supply suddenly, device automatically switches to solenoid valve 1 working condition, be that the contactor normally-closed contact disconnects, the normally opened contact closure, red led L1 extinguishes, and green indicating lamp L2 lights, and solenoid valve 1 is given in storage battery 2 discharges, solenoid valve 1 is connected emergent water and is flowed into vacuum furnace, thereby plays the effect to the body of heater cooling.After power system restoration was normal, device automatically switched to original state again.Solenoid valve is in the tutorial light that different working staties has respective color simultaneously to be lighted, and the operator can draw the solenoid valve state intuitively.In the device total input-wire, insert fus, during voltage functuation, played the whole device of protection.Manual control switch 4 of storage battery major loop series connection when factory building power supply system regular maintenance need have a power failure, can disconnect the solenoid valve loop by manual operation switch, prevents the solenoid valve misoperation.
