The multifunctional hydraulic valve block for the steel ladle sliding nozzle has the beneficial effects that the size of a hydraulic valve integrated block is reduced; an electric device is simplified; the tube replacing and pressure relieving can be manually performed; under an emergency condition, the manual control on the hydraulic valve level for the steel ladle sliding nozzle is realized; the turnover for the steel ladle is quickened; the production accidents are reduced; the safe running and safe production for the steel ladle sliding nozzle are ensured.
Description
Technical field
The utility model relates to a kind of multi-functional ladle slide gate nozzle hydraulic valve bank.
Background technology
Steel ladle sliding water gap is a very important device controlling molten steel flow in ladle, if this device is in use worn steel accident, its consequence is very serious, not only can cause casting machine to break draws, burn out the generation of the pernicious production accidents such as continuous casting machine, also restricted the stable smooth operation of producing, serious threat the safety of the person and equipment.
Further quickening along with steel-making rhythm, to accelerating ladle turnover, reducing production accident has higher requirement, and the safe operation that guarantees slide gate nozzle is one of precondition of safety in production, minimizing production accident, yet present steel ladle sliding water gap hydraulic valve bank manufacturing cost is higher, and control device profile is larger, is not easy to fitting operation, when being in an emergency, can not carry out Artificial Control, also not have product or the method that can address these problems to occur at present.
Utility model content
The purpose of this utility model is to provide a kind of multi-functional ladle slide gate nozzle hydraulic valve bank, can reduce the accident at steel ladle sliding water gap place, guarantees the stable operation of production, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of multi-functional ladle slide gate nozzle hydraulic valve bank, comprise hand-operated direction valve and fuel inlet ball check valve, after fuel inlet ball check valve, be provided with speed control loop, be included in the first solenoid directional control valve, the second solenoid directional control valve and the one-way throttle valve that on described speed control loop, arrange, described the first solenoid directional control valve and one-way throttle valve series connection, in parallel between described the first solenoid directional control valve and described the second solenoid directional control valve, on described pressure control loop, be provided with manual ball valve.
Above-mentioned multi-functional ladle slide gate nozzle hydraulic valve bank, described manual ball valve comprises the first manual ball valve and the second manual ball valve.
The beneficial effects of the utility model are: the size that has reduced hydraulic valve integrated package, simplified electric device, realized the function of manual replace tubes pressure release, Artificial Control that can be to steel ladle sliding water gap hydraulic valve level when there is the state of emergency, accelerated ladle turnover, reduce production accident, guaranteed safe operation and the safety in production of ladle nozzle.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of multi-functional ladle slide gate nozzle hydraulic valve bank of the prior art;
Fig. 2 is the structural representation of multi-functional ladle slide gate nozzle hydraulic valve bank described in the utility model embodiment;
In figure:
1, hand-operated direction valve; 2, fuel inlet ball check valve; 3, the first solenoid directional control valve; 4, the second solenoid directional control valve; 5, one-way throttle valve; 6, manual ball valve; 7, the first manual ball valve; 8, the second manual ball valve.
The specific embodiment
As shown in Figure 1-2, original steel ladle sliding water gap hydraulic valve bank has adopted plurality of electromagnetic reversal valve, even relief valve has also adopted solenoid directional control valve, single unit system takes up room greatly like this, the design of integrated package is complicated, and be unfavorable for Artificial Control, when a kind of multi-functional ladle slide gate nozzle hydraulic valve bank described in the utility model embodiment is specifically used, comprise hand-operated direction valve 1 and fuel inlet ball check valve 2, described hand-operated direction valve 1 is for the driving manually of steel ladle sliding water gap oil cylinder, after fuel inlet ball check valve 2, be provided with speed control loop, be included in the first solenoid directional control valve 3 arranging on described speed control loop, the second solenoid directional control valve 4 and one-way throttle valve 5, described one-way throttle valve is for regulating the movement velocity of slide gate nozzle hydraulic cylinder, described the first solenoid directional control valve 3 and described the second solenoid directional control valve 4 are for controlling the direction of motion of slide gate nozzle hydraulic cylinder, described speed control loop has formed direction control circuit simultaneously, described the first solenoid directional control valve 3 and one-way throttle valve 5 series connection, described the first solenoid directional control valve 3 and 5 actings in conjunction of described one-way throttle valve are in the adjusting at a slow speed of described slide gate nozzle hydraulic cylinder, in parallel between described the first solenoid directional control valve 3 and described the second solenoid directional control valve 4, described the second solenoid directional control valve 4 is for the quick adjustment of described slide gate nozzle hydraulic cylinder, on described pressure control loop, be provided with manual ball valve 6, described manual ball valve 6 comprises the first manual ball valve 7 and the second manual ball valve 8.
Described the first manual ball valve 7 and described the second manual ball valve 8 play replace tubes pressure release effect, when the high-pressure rubber pipe of slide gate nozzle hydraulic cylinder carries out replace tubes, close described fuel inlet ball check valve 2, open described the first manual ball valve 7 or the second manual ball valve 8 or open described the first manual ball valve 7 simultaneously, the second manual ball valve 8 carries out pressure release.
The utility model has substituted original two four-way electromagnetic reversing valves with manual ball valve 6, not only realized replace tubes pressure release has been carried out to Artificial Control, also reduced the integrated package design of valve group, simplified electrical control, make valve block structure compacter, take up room less, the safety in production of ladle nozzle has been played to important meaning.
Above-described embodiment is only for the utility model example is clearly described, and the not restriction to the utility model specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any apparent variations of being extended out within spirit of the present utility model and principle or change are still among the protection domain in the utility model claim.
