Description
Technical field
The utility model relates to a kind of shading aperture apparatus, particularly the tubulose preventing dust shading aperture apparatus on a kind of respirator steam supply valve.
Background technology
There is scene, rescue measure and maintenance work in contaminated area, fire that current positive-pressure air respirator can be widely used in other possibility anoxic areas such as fire-fighting, chemical industry, metallurgy, miner, oil.Be designed for user and protect toxic gas, poisonous particle and aerosol, oxygen content lower than the severe working environment such as 15% anaerobic environment, the smog that fire causes, be for fireman or speedily carry out rescue work rescue personnel under the various environment such as dense smoke, poison gas, steam or anoxic, put out a fire safely and effectively, a kind of buoyant apparatus of rescue and relief work and rescue.
At present, positive-pressure air respirator mainly comprises gas cylinder, full facepiece mask, pressure-display device and warning device.Wherein the existing pressure head-up display of positive-pressure air respirator (SCBA) comprises transmitting terminal and looks squarely display end two parts.Transmitting terminal is generally placed in back of the body tool or front, by high-voltage tube, is connected with transmitting terminal.Transmitting terminal can be divided into and can be divided into wired and wireless two kinds with the connected mode of looking squarely display end.Look squarely display end and generally all adopt Led display mode, when storage pressure is during at 30-10MPa, Led green light Chang Liang; When storage pressure is during at 10-6MPa, amber light Chang Liang; When storage pressure is when 6MPa is following, red light is always glittering; That also disposes in addition power supply low-voltage alarm lamp, wireless mode is also provided with paired light.
Wired connection look squarely display end, be generally all arranged on steam supply valve, its Led position is all near the be connected position of interface of steam supply valve and full facepiece mask, earlier, the distance of Led lamp and eyes the longest also less than 120mm, generally all at 100-110mm; Wireless connections look squarely display end, major part is arranged on full facepiece mask inside, the distance of its Led and eyes is less than 80mm a bit.Its display unit and eye distance are short, and it is very painstaking that user seems, and easily produce visual fatigue, affects rescue work; And steam supply valve is to be exposed to airbornely, and user is not easy to observe its information, affects user of service and makes a decision, and affects its safety.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the aperture apparatus of the tubulose preventing dust shading on a kind of respirator steam supply valve is provided.
To achieve these goals, the measure that the utility model is taked:
Tubulose preventing dust shading aperture apparatus on a kind of respirator steam supply valve, comprise gas cylinder, gas cylinder is fixed on back bracket by bandage, on back bracket, be connected with strap component, on gas cylinder, by a bottle main valve, pressure reducer and middle pressure pipe, be connected with steam supply valve, on steam supply valve, be connected with full facepiece mask, transparent window is installed on full facepiece mask, on described steam supply valve, offer tubulose preventing dust shading hole, tubulose preventing dust shading hole is near full facepiece mask one end opening, away from one end of full facepiece mask, is provided with head-up display;
Described tubulose preventing dust shading hole is symmetrical two, near full facepiece mask one end opening part, lens is installed.
The beneficial effects of the utility model: device adopts closed design, from display screen to steam supply valve, all adopted duct type shade, gear cigarette is dustproof, shading, even and if weak display brightness also can clearly be seen displaying contents clearly, and be not subject to the impact of ambient light power, and be conducive to save power supply, greatly improved user of service's operating efficiency, and fireman can be made decision better, to ensure the safety of human life.
Accompanying drawing explanation
Fig. 1, respirator overall structure schematic diagram of the present utility model.
Fig. 2, steam supply valve internal structure schematic diagram of the present utility model.
The specific embodiment
Tubulose preventing dust shading aperture apparatus on a kind of respirator steam supply valve, comprise gas cylinder 92, gas cylinder 92 is fixed on back bracket 91 by bandage, on back bracket 91, be connected with strap component 93, on gas cylinder 92, by a bottle main valve 17, pressure reducer 94 and middle pressure pipe 95, be connected with steam supply valve 3, on steam supply valve 3, be connected with full facepiece mask 1, on full facepiece mask 1, transparent window is installed, on described steam supply valve 3, offer tubulose preventing dust shading hole 11, tubulose preventing dust shading hole 11 is near full facepiece mask 1 one end openings, away from one end of full facepiece mask 1, is provided with head-up display 21.
Described tubulose preventing dust shading hole 11 is symmetrical two, near full facepiece mask 1 one end opening part, lens 22 is installed.
The utility model is installed to the enterprising enforcement of respirator to be used, full facepiece mask 1 is worn on the face, eyes are by shading preventing dust hole, the lens on steam supply valve and the shading preventing dust hole of eyeglass, full facepiece mask, i.e. the information of Observable display unit, and be convenient to intuitively know fast every data message.Full device adopts closed design, from display screen to steam supply valve, all adopted duct type shading preventing dust device, gear cigarette is dustproof, shading, even and if weak display brightness also can clearly be seen displaying contents clearly, and be not subject to the impact of ambient light power, and be conducive to save power supply, greatly improved user of service's operating efficiency, and fireman can be made decision better, to ensure the safety of human life.
Above embodiment, only for the technical solution of the utility model is described in more detail, can not be interpreted as the restriction to the utility model protection domain; Some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
