Abstract
The utility model discloses a scram device for diesel generating set, include the air inlet pipeline and set up the valve of dying on the air inlet pipeline, but the valve of dying includes the valve rod of valve body, disk seat up -and -down motion and fixes the valve clack at the valve rod lower extreme, the valve rod is driven by drive arrangement, drive arrangement is controlled by the controller, and under the state of dying, the lower terminal surface of valve clack is closely laminated with the up end of disk seat. Scram device for diesel generating set, realizes dying through the valve of dying through set up the valve of dying on the air inlet pipeline when meetting emergency to the diesel engine is shut down rapidly, has the fast characteristics of shutting down, in addition, and characteristics that the valve of dying has simple structure, easily realizes, sealing performance is good.
Description
Technical field
The utility model relates to diesel generating set, particularly relates to a kind of diesel generating set emergency stop device.
Background technique
Diesel generating set take diesel engine as prime mover, drags a kind of power apparatus of synchronous generator generating.Diesel generating set be a kind ofly to start rapidly, operation and maintenance convenience, little investment, the electricity generating device stronger to the conformability of environment.
At present, it is all rely on diesel engine oil-cut to control that the diesel generating set on market is shut down, but; there is certain drawback in this kind of halt mode; when oil-break is shut down, still have a certain amount of diesel oil in diesel-engine body and in diesel-oil filter, it is enough to allow diesel engine continuous running 1 ~ 2 minute; thus diesel engine cannot be made to stop immediately; in this case, once run into Overspeed of diesel Engine, very serious consequence can be caused; thus, be badly in need of solving.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of diesel generating set emergency stop device, and it can make diesel engine shut down rapidly.
The purpose of this utility model is achieved through the following technical solutions:
A kind of diesel generating set emergency stop device, comprise air inlet pipeline and be arranged at the ACV Air Cut Valve on air inlet pipeline, described ACV Air Cut Valve comprises valve body, valve seat, the valve rod that can move up and down and is fixed on the flap of valve rod lower end, described valve rod is driven by drive unit, described drive unit is controlled by controller, under state of dying, the lower end surface of flap and the upper-end surface of valve seat fit tightly.
As a kind of preferred version of the present utility model, described drive unit is any one in cylinder, oil cylinder, electric cylinder.
As a kind of preferred version of the present utility model, the lower end surface of described flap is convex face, and the upper-end surface of described valve seat is the concave arc surface matched with it.
As a kind of preferred version of the present utility model, described controller is PLC.
The beneficial effects of the utility model are; described diesel generating set emergency stop device by arranging ACV Air Cut Valve on air inlet pipeline; in case of emergency; realize dying by ACV Air Cut Valve; thus diesel engine is shut down rapidly; have and shut down fireballing feature, in addition, ACV Air Cut Valve has the advantages that structure is simple, be easy to realization, good seal performance.

Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.Be understandable that, embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of the utility model diesel generating set emergency stop device.
In the present embodiment, a kind of diesel generating set emergency stop device, the ACV Air Cut Valve comprising air inlet pipeline 1 and be arranged on air inlet pipeline 1, described ACV Air Cut Valve comprises valve body 2, valve seat 3, the valve rod 4 that can move up and down and be fixed on the flap 5 of valve rod 4 lower end, described valve rod 4 is driven by cylinder 6, described cylinder 6 is controlled by controller, described controller is PLC, the lower end surface of described flap 5 is convex face, the upper-end surface of described valve seat 3 is the concave arc surface matched with it, sealing gasket 7 is provided with between flap 5 and valve seat 3, under state of dying, the lower end surface of flap 5 and the upper-end surface of valve seat 3 fit tightly.
When an emergency happens, such as: the situations such as hypervelocity, low fuel pressure, water temperature height, controller sends signal, and then making cylinder 6 drive flap 5 to move down, the lower end surface of flap 5 and the upper-end surface of valve seat 3 fit tightly, thus ACV Air Cut Valve is closed, make diesel oil in piston cylinder, can not get ozone to mix with it, compression and combustion, diesel engine can not get fuel supply, shuts down rapidly; When urgency is removed, controller sends signal, and then cylinder 6 is driven on flap 5 move, and recovers normal for gaseity, thus diesel engine can normally be worked.
It is worth mentioning that, although in above-described embodiment, adopt cylinder 6 to be with ovable valve stem 4 to move up and down, the utility model is not limited thereto, and oil cylinder, electric cylinder also can be adopted to move up and down to be with ovable valve stem 4.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model does not limit by above-described embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (5)
