Description
Technical field
The present invention relates to a kind of decompressor, especially one we meet an urgent need for ship's space the decompression dress of respiratory system
Put.
Background technology
During ship's navigation, it is possible that some affect crewman's health and the special circumstances of life security, when this
Time crewman when cannot escape immediately and need to carry out the operation of necessity or wait for rescue, it is necessary to ensure that crewman can eupnea
To sustain life.Traditional emergent breathing relies primarily on the instrument such as oxygen cylinder, canister respirator, the adaptation energy to various special environments
Power is limited, and it is relatively big to take up room, and is difficult to accomplish that crew is equipped with.
When situations such as occurring air pollution, environmental hazard, blast, fire, water logging and not clear material diffusion in cabin causes
Crewman cannot eupnea when can not escape immediately again, can be by the air system of different pressures grade intrinsic on ship as gas
Source inputs, and provides the input source of the gas of pressure stability for multiple rear end equipment simultaneously, and participate in after the filtration of this decompressor, decompression
Respiratory system uses, to guarantee that crewman with eupnea, and can be carried out the operation of necessity or wait for rescue within the specific limits,
Effective guarantee is provided for crewman's life security.Accordingly, it would be desirable to design original air pipe system in one only uses cabin
Decompressor, and require compact conformation volume little, can oneself back up (two-way air can be simultaneously connected with, the most standby), ring
Border strong adaptability (not by extraneous the factor such as medium, pressure affected), simple to operate, keep in repair convenient, wide (a set of decompression of coverage rate
The rear end of device can simultaneously for more than 80 people breathe) etc. feature.
Summary of the invention
It is desirable to provide a kind of ship's space that can be applied to is met an urgent need the decompressor of respiratory system, when going out in cabin
The situations such as existing air pollution, environmental hazard, blast, fire, water logging and not clear material diffusion cause crewman cannot eupnea again
When can not escape immediately, air system supply intrinsic in utilizing cabin, set for multiple rear ends after decompressor filtration, decompression
Standby (breathing air relief valve) provides the input source of the gas (0.6 ~ 0.7MPa air pressure) of pressure stability simultaneously, and participates in respiratory system use.

Equipped with steel ball 25, pressure release spring 26 and plug screw 27.Bottom 37 bottom decompressor has osculum, when there being hydrops in pipeline,
Can unscrew bottom, hydrops can be discharged through osculum.
Decompressor should the most first carry out pressure regulation, and the pressure i.e. adjusting air bag chamber makes decompressor outlet pressure
Meeting and use requirement, upper cover 15 and boring cover 17 constitute the airbag chamber of pressure reducing valve component so that not by outward during pressure reducing valve component pressure regulation
The impact of boundary's pressure;There is heat insulating coat 16 on upper cover 15 and boring cover 17 surface so that pressure reducing valve component in the range of certain time, its
Use and do not affected by ambient temperature.During decompressor pressure regulation, first slowly unscrew two needle valve cores 23, make the air of entrance point enter
Enter airbag chamber indoor.Observe delivery gauge numerical value corresponding on pressure dial plate 6, when delivery gauge numerical value reaches setting
Time, successively screw the needle valve core 23 on upper cover 1 and valve body 8.The bottom of valve body 8 side is provided with steel ball 25, pressure release spring 26 and
Plug screw 27, scalable pressurising pressure, when in Plenum Process, airbag chamber pressure exceedes setting, medium can promote steel ball 25 to compress
Pressure release spring 26, and the hole in the middle of plug screw 27 are discharged.
The principle of decompressor decompression is: the compressed air of airbag chamber indoor damping hole on boring cover 17 acts on film
On sheet 18, band dynamic diaphragm 18 promotes piston plate 41 to move downward so that push rod 35 also moves downward and departs from seal receptacle 39 and formed
Restriction.Air dielectric enters pressure reducing valve component 44 entrance point through entrance point shut-off valve assemblies 43, produces through sealing surface restriction
Raw throttling action makes pressure medium change, and flows through connection spiral shell dish 31, acts on and produces one on piston plate 41 upwards
Active force and be applied on diaphragm 18, after this active force and airbag chamber effect form balance for the active force of diaphragm 18, top
Bar 35 no longer moves so that push rod 35 and seal receptacle 39 keep certain aperture, it is ensured that decompressor outlet pressure is stable.
