Abstract
A kind of remote emergency control system of unpowered refueling device, including gas cylinder are the utility model is related to, in addition to reel is controlled with the remote emergency that gas cylinder is connected by pipeline, the outlet of the remote emergency control reel is connected with Pneumatic valve by tracheae；The Pneumatic valve is connected with working connection pipeline.The utility model is that unpowered refueling device increases remote emergency control system, and the function of remote emergency control is realized to whole pipeline.More safe and reliable in the utility model structure, installation is easy, easy to maintenance, and cost is cheap, easily operated, and the hidden danger of fire, positive effect are eliminated using source of the gas as power.
Description
Technical field
The utility model belongs to fueling operation control field, is specifically related to a kind of remote emergency of unpowered refueling device
Control system.
Background technology
Unpowered refueling device has the characteristics of compact structure, maneuverability, accordingly can be applied to airport emergency fueling operation,
But because its own does not possess power output, required driving force can not be provided for remote emergency control function, thus it is domestic at present
Outer unpowered refueling device is generally not provided with remote emergency control function.Domestic Civil Aviation Airport regulation remote emergency control is daily
One of fueling operation household function, set so lacking the passive refueling device of the function restriction as the daily oiling in Civil Aviation Airport
It is standby, that is, limit the adaptability of unpowered refueling device.
Utility model content
Technical problem to be solved in the utility model is the shortcomings that overcoming prior art, there is provided a kind of conjunction simple in construction
Reason, reliability are high, the remote emergency control system of the flexible unpowered refueling device of operation.
In order to solve the above technical problems, the utility model provides a kind of remote emergency control system of unpowered refueling device
System, including gas cylinder, it is characterised in that：Also include controlling reel, institute with the remote emergency that gas cylinder is connected by pipeline
The outlet for stating remote emergency control reel is connected with Pneumatic valve by tracheae；The Pneumatic valve is connected with working connection pipeline.
The technical scheme that the utility model further limits is：Between the gas cylinder and remote emergency control reel
Pressure-reducing valve is installed.
Further, the remote emergency control reel is provided with the handle of control air-flow opening and closing.
Further, the Pneumatic valve includes pilot valve and main valve, the pilot valve and the outlet of remote emergency control reel
Connection；Air-flow enters back into the bypass of main valve by pilot valve.
Further, pressure gauge is installed on the gas cylinder.
Further, the gas cylinder is provided with air inlet.
The beneficial effects of the utility model are：The utility model is that unpowered refueling device increases remote emergency control system
System, the function of remote emergency control is realized to whole pipeline.It is more safe and reliable in the utility model structure, installation easily,
Easy to maintenance, cost is cheap, easily operated, and the hidden danger of fire, positive effect are eliminated using source of the gas as power.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of remote emergency control system for unpowered refueling device that the present embodiment provides, as shown in Figure 1：Including high pressure
Gas cylinder 1, in addition to reel 5 is controlled with the remote emergency that gas cylinder 1 is connected by pipeline, the remote emergency controls reel 5
Outlet Pneumatic valve is connected with by tracheae 6；The Pneumatic valve is connected with working connection pipeline 9.
Pressure-reducing valve 3 is installed between the gas cylinder 1 and remote emergency control reel 5.
The remote emergency control reel is provided with the handle 4 of control air-flow opening and closing.Air pressure can be closed or turned on to gas control
Valve, the control to Pneumatic valve is realized, so as to reach the break-make control to working connection pipeline, reach the purpose for realizing emergency flight control.
The Pneumatic valve includes pilot valve 7 and main valve 8, the pilot valve 7 and remote emergency control reel outlet；Gas
Stream enters back into the bypass of main valve 8 by pilot valve 7.Pilot valve is connected to the bypass before and after main valve plug, and injection air-flow can make guide
Pilot valve in valve keeps the bypass to circulate so that the spring dynamic balance inside pressure differential and main valve plug before and after main valve plug,
So as to keep main valve plug to open；When airless injects, pilot valve can move and end aforesaid by-pass so that including main valve plug
Closed in the presence of portion's spring force.
Pressure gauge 2 is installed on the gas cylinder.The gas cylinder is provided with inflation inlet, it can be inflated, air pressure
Table observable gas cylinder air pressure inside, is able to determine when to be full of when being easy to be inflated gas cylinder, can determine that simultaneously
When must be to its tonifying Qi.The utility model increases reliable and stable power output on unpowered refueling device, and it is remote to reach driving
Journey emergency flight control function, is worthy to be popularized.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent substitution or equivalent change
The technical scheme to be formed is changed, all falls within the protection domain of the requires of the utility model.
