The present invention relates to a humidifier for an air pressure chamber. The present invention is characterized in that an air nozzle and a water outlet are arranged inside an air pressure chamber; mouth parts of the air nozzle and the water outlet are adjacently arranged, wherein the air nozzle is connected with an air source positioned outside the air pressure chamber through pipelines, and the water outlet is connected with a water storage tank positioned outside the air pressure chamber through pipelines; the pressure chamber preferably has equal air pressure with the water storage tank, which can be realized by the communication of a special pipeline arranged between the pressure chamber and the water storage tank and can be realized by the following method that the pipelines connecting the water outlet and a water source are provided with ventilating holes communicated with the pressure chamber in pipe walls positioned inside the pressure chamber. The present invention can effectively solve the problem that dry environment caused by temperature drop, dehumidification, etc. in manned pressure chambers such as a medical oxygen chamber, a diving decompression chamber, etc., leads to the discomfort of the throats of personnel entering chambers. In addition, static electricity inside the chambers can be eliminated through humidification, and accordingly, chamber burning accidents in the medical oxygen chamber are effectively prevented.
Description
Technical field
The present invention relates to a kind of damping device that is used for manned pressure chambers such as hyperbaric oxygen chamber, submersible decompression chamber.
Background technology
In manned pressure chambers such as hyperbaric oxygen chamber, submersible decompression chamber, because the influence that air-conditioning temperature-reducing dries in the cabin, environment presents the low humidity drying regime in the cabin and make, unfavorable to human body, simultaneously drying also causes static easily, especially is used for the oxygen pressurization hyperbaric oxygen chamber for the treatment of, if the untimely loss of static, serious might cause pyrophoricity accident, by the loss static effectively then of humidification in the cabin; Therefore, the U.S., Japan and other countries have been formulated standard, require humidity in the cabin must reach the requirement of certain numerical value, and at present, China still do not have such damping device.
Summary of the invention
Technical problem to be solved by this invention is how a kind of device that can carry out humidification to manned pressure chambers such as hyperbaric oxygen chamber, submersible decompression chambers is provided; Further, how to make this damping device can regulate humidity in the cabin automatically, make it to maintain a constant set value comparatively.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: an air nozzle and a faucet are set in existing pressure chamber, both oral areas are provided with for the next-door neighbour, wherein air nozzle links to each other with the source of the gas that is positioned at out of my cabin by pipeline, faucet links to each other by the water tank that pipeline and is positioned at out of my cabin, and described barochamber has the air pressure that equates with described water tank.
Described barochamber has the air pressure that equates with water tank can be by being communicated with realization with a pipe special between the two, can realize in the following manner that also promptly described connection faucet has the passage that is connected with barochamber with the pipeline at water source on the tube wall that is positioned at the cabin part;
For realizing the automatic humidification function, can between described air nozzle and described source of the gas, be serially connected with an autocontrol valve, and a humidity sensor is set in the cabin, this humidity sensor links to each other with the automatic interrupter that the described autocontrol valve of a control opens and closes with lead.
The present invention can solve effectively in manned pressure chamber such as hyperbaric oxygen chamber, submersible decompression chamber and to dry etc. former thereby the environmental drying that causes and cause the into drawback of cabin personnel throat discomfort because of cooling, in addition, also can eliminate static in the cabin by humidification, thereby prevent the burning cabin accident of hyperbaric oxygen chamber effectively.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, on existing pressure chamber 1 afterbody end socket wall, be fixed with an air nozzle 2 and a faucet 3 are set by bearing support 11, both oral area next-door neighbours are provided with and are vertically opposite, wherein air nozzle 2 is linking to each other with source of the gas through autocontrol valve 7, air relief valve 8 out of my cabin by pipeline 21, this source of the gas can be a compressed air source, also can be that bottle oxugen is formed through second depressurized, as long as its outlet air pressure is greater than the cabin internal gas pressure; Faucet 3 then links to each other with the water tank 5 that is positioned at out of my cabin by pipeline 31, and water tank 5 tops have water filling port, and the bottom has sewage draining exit and is respectively arranged with control valve;
When high velocity air is sprayed by air nozzle 2, according to hydromechanical Bai Nuli principle, form a low-pressure area around the air nozzle 2, and the opening of faucet 3 promptly is positioned at this low-pressure area, because the other end pressure of faucet connecting line 31 is constant, so just form a pressure reduction at two ends of faucet pipeline 31, with this pressure reduction is power, water in the water tank 5 promptly by continuously by the road 31 from faucet 3 sucking-offs, the high velocity air through air nozzle 2 ejections brushes again, is about to water column and blows out mist;
Since general manned barochamber have boost, voltage stabilizing, three kinds of work process of blood pressure lowering, its force value differs, even in the voltage stabilizing stage, its force value also fluctuates; For making water tank 5 change in the overall process humidifying and water supplying at any time at the pressure of barochamber, the water surface pressure of water tank 5 inside must be equal to all the time with the operating pressure of barochamber 1, for this reason, be positioned at the described connection faucet and the pipeline 4 at water source on the tube wall of cabin part and having the passage 41 that is connected with barochamber, referring to Fig. 2, Fig. 3, at this moment, the water filling port of water tank 5 also can be opened the part outside pipeline 4 is positioned at barochamber 1, i.e. 42 among the figure;
In the present embodiment, described autocontrol valve 7 adopts explosion-proof solenoid valve, and for adding wet practice automatically, it opens and closes this explosion-proof solenoid valve by a relay 9 controls, and its normally opened contact is in the wire loop that is connected on explosion-proof solenoid valve 7; In barochamber 1, also be provided with simultaneously a humidity sensor 6, this humidity sensor 6 can cause the variation of the physical quantity (as: resistance, electric capacity, conductivity) of self when humidity changes, in the present embodiment, select capacitance type sensor for use, specifically can adopt IH3605 type thermosetting polyester capacitance type sensor; These humidity sensor 6 usefulness leads 61 strings are on the control circuit of the wire loop of described relay 9, and the concrete circuit of this control circuit then can adopt prior art, does not describe in detail;
For having two kinds of duties of manual humidification and automatic humidification, also string has a single-pole double throw type K switch as change-over switch in the wire loop of described electromagnetic valve 7, its movable contact links to each other with positive source, one of them stationary contact (manually) directly connects the coil of electromagnetic valve 7, and another stationary contact (automatically) then links to each other with the movable contact of described relay 9;
KC is that a double-contact is to relay, in the present embodiment as the main switch of The whole control circuit among the figure.
