Abstract
The utility model provides an inflating system for a lifeboat. The inflating system comprises an ejector, a high-pressure throat tube and a bottle valve assembly, wherein the ejector is connected with the bottle valve assembly through the high-pressure throat tube, the periphery of the ejector is also provided with a separation cabin structure, the separation cabin structure comprises a clamp hoop, an ejector connecting ring, a separation cabinet cut sheet, a separation cabinet connecting sheet and an inner sealing strip, the ejector is arranged on a lifeboat floating tube through the clamp hoop and the ejector connecting ring, and the separation cabinet cut sheet is bonded onto the lifeboat floating tube through the separation cabin connecting sheet and the inner sealing strip. The inflating system has the beneficial effects that the inflating efficiency of the lifeboat is improved, and the lifeboat floating tube can be fast inflated and formed. The weight of the required compressed gas is reduced, so the size of an air bottle is reduced, and the weight of the lifeboat is reduced. Through the separation cabin structure arranged at the periphery of the ejector, a pressure region can be enabled to be formed at the periphery of the ejector during the lifeboat inflation, the ejector is enabled to be always positioned above the water level when the lifeboat is inflated on the water, and the water suction of the ejector is prevented.
Description
Technical field
The utility model relates to aviation water survival technology, is specifically related to a kind of lifeboat air inflator system.
Background technology
Before this series life ship development, domestic do not have specialized system to develop the big-and-middle-sized lifeboat that is used for large and medium-sized transport plane collective lifesaving waterborne.International aviation lifesaving's ship requires inflationtime to be no more than 1 minute, requires simultaneously the lifeboat volume little lightweight.Domestic existing lifeboat all adopts conventional CO
2Gas cylinder is as source of the gas, and inflationtime can be controlled in 1 minute.And big-and-middle-sized lifeboat hull volume is large, needs a large amount of sources of the gas to inflate shaping.If rely on separately pressure gas to come its inflation, the gas cylinder volume and weight is large, causes lifeboat final packaging size and weight to be difficult to reach general international standard.In order to make big-and-middle-sized lifeboat can inflate shaping in 1 minute, and whole lifeboat packing measurement and weight reaches general international standard, must adopt the air inflator system of a kind of high efficiency, high reliability.
Summary of the invention
The technical problems to be solved in the utility model is for the problem that big-and-middle-sized lifeboat inflationtime in prior art exceeds standard, to provide a kind of efficient of lifeboat air inflator system and lifeboat air inflator system of reliability of improving.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
A kind of lifeboat air inflator system, it comprises injector, high pressure trunnion, cylinder valve assembly, described injector is connected with the cylinder valve assembly by the high pressure trunnion.
In such scheme, also be provided with compartment structure around described injector, described compartment structure comprises clip, injector coupling link, separation cut-parts, separation connecting strap and interior sealing band, injector is arranged on the lifeboat floating drum by clip and injector coupling link, and the separation cut-parts are bonded on the lifeboat floating drum by separation connecting strap and interior sealing band.
During Dump valve on opening lifeboat cylinder valve assembly, gas in cylinder valve assembly gas cylinder flows to injector by the high pressure trunnion, inject in the lifeboat floating drum, utilize simultaneously the gettering effect of injector, air is sucked in the lifeboat floating drum simultaneously, improved charge efficiency, made the injection inflation shaping rapidly of lifeboat floating drum.Due to the weight that has reduced required pressure gas, thereby reduce the gas cylinder volume, reduced lifeboat weight.
Increase compartment structure around injector, compartment structure is guaranteed lifeboat when inflation mineralization pressure district around injector, and when guaranteeing that lifeboat is inflated on the water, injector is positioned on the water surface all the time, prevent the injector suction, guarantee lifeboat injection inflation shaping rapidly.
The beneficial effects of the utility model: improved the charge efficiency of lifeboat, made the lifeboat floating drum can inflate rapidly shaping.Due to the weight that has reduced required pressure gas, thereby reduce the gas cylinder volume, reduced lifeboat weight.When compartment structure can be guaranteed the lifeboat inflation around injector around injector the mineralization pressure district, when guaranteeing that lifeboat is inflated on the water, injector is positioned on the water surface all the time, prevents the injector suction.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further.
With reference to Fig. 1 ~ shown in Figure 2, a kind of lifeboat air inflator system described in the utility model, it comprises injector 1, high pressure trunnion 2, cylinder valve assembly 3, described injector 1 is connected with cylinder valve assembly 3 by high pressure trunnion 2.
With reference to Fig. 2 ~ shown in Figure 4, also be provided with compartment structure around described injector 1, described compartment structure comprises clip 5, injector coupling link 6, separation cut-parts 7, separation connecting strap 8 and interior sealing band 9, injector 1 is arranged on lifeboat floating drum 4 by clip 5 and injector coupling link 6, and separation cut-parts 7 are bonded on lifeboat floating drum 4 by separation connecting strap 8 and interior sealing band 9.
During work, during Dump valve on opening lifeboat cylinder valve assembly 3, gas in cylinder valve assembly 3 gas cylinders flows to injector 1 by high pressure trunnion 2, inject in lifeboat floating drum 4, utilize simultaneously the gettering effect of injector 1, air is sucked in lifeboat floating drum 4 simultaneously, improved charge efficiency, make lifeboat floating drum 4 injection inflation shaping rapidly.Due to the weight that has reduced required pressure gas, thereby reduce the gas cylinder volume, reduced lifeboat weight.
Increase compartment structure around injector 1, compartment structure is guaranteed lifeboat when inflation mineralization pressure district around injector 1, and when guaranteeing that lifeboat is inflated on the water, injector 1 is positioned on the water surface all the time, prevent injector 1 suction, guarantee lifeboat injection inflation shaping rapidly.
Above-described is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalence of therefore doing according to the utility model claim changes, and still belongs to protection domain of the present utility model.
