Abstract
The utility model relates to an isolated-type forced-air self rescue device and is in particular suitable for self rescue of field staff on the occasions when harmful gas outbursts or oxygen is insufficient under a shaft in a coal mine and accidents happen in tunnels and subways. The isolated-type forced-air self rescue device comprises an air source connector and a pressure reduction regulator which are connected in sequence and is characterized in that the pressure reduction regulator is connected with at least one airflow regulating valve, and each airflow regulating valve is correspondingly connected with a flow meter and an isolated-type breathing mask in series connection with the flow meter. The isolated-type forced-air self rescue device can individually indicates the air flow consumption level of each user and individually regulates the air flow according to the air flow consumption level.
Description
Technical field
The utility model relates to a kind of compressed air self-help apparatus, is particularly useful under the coal mine taking place under the outstanding or clear condition of anoxic of pernicious gas, and the Field Force saves oneself, and the Field Force's saves oneself when also being applicable to tunnel, subway something unexpected happened.
Background technology
Compressed air self-help apparatus is a kind of isolated respiratory protection equipment.Be mainly used in the colliery or toxic and harmful takes place in the operating environment that normal atmospheric is pressed when giving prominence to, the Field Force has little time to withdraw, and can put on the isolation breathing mask nearby and save oneself, and is guaranteeing that eupnea is not subjected to wait for rescue under the prerequisite of poison gas injury.
Present existing compressed air self-help apparatus include pocket-type and face mask type, the complicated operation of pocket-type wherein, the life-span is short; utilize less; the compressed air self-help apparatus of face mask type includes air inlet pipe, pressure regulator valve, escape pipe and face shield and forms, though it can play the effect of isolating respiratory protection.But still exist some following problems: 1, flow regulator is simple inadequately, can not carry out independent Flow-rate adjustment according to every actual needs of wearing; 2, the actual consumption flow that can't indicate every wearer causes the waste of air.
The utility model content
The technical problems to be solved in the utility model is: a kind of air-flow consumption that can indicate every wearer separately is provided, and can regulates the isolation type compressed air self-help apparatus of flow according to the air-flow consumption separately.
In order to solve the problems of the technologies described above, the utility model provides a kind of isolation type compressed air self-help apparatus, include the gas source connector and the pressure reducing regulator that connect in turn, wherein be connected with at least one barometric damper on the pressure reducing regulator, each barometric damper correspondence is connected with a flowmeter and the isolation type breathing mask that is serially connected on the flowmeter.
Adopt the isolation type compressed air self-help apparatus of technique scheme to have following advantage: 1, owing to the flowmeter that is serially connected with of each isolation type breathing mask correspondence, can indicate the real-time empty throughput consumption of wearing separately; 2, owing to the barometric damper that is serially connected with of each flowmeter correspondence, therefore can adjust air mass flow according to the air mass flow of practical intelligence, avoid waste.
As preferred version, consider the demand in the actual use, simultaneously for guarantee isolation type press the wind respirator not the excess load running cause danger, described flow control valve, flowmeter and the isolation type breathing mask that connects successively is provided with five groups.
As preferred version, consider the ease of use of pressure reducing regulator, be convenient to know real-time pressure simultaneously, described pressure reducing regulator is provided with Pressure gauge.
As preferred version, consider after the air decompression is regulated to produce part water, between described pressure reducing regulator and barometric damper, be provided with gas-liquid separator.
As preferred version, the wearer who considers breathing mask may need to carry out the position and move action or measure to do some necessity, consider that simultaneously the residing environment of breathing mask may cause it dirty, for convenience it being carried out dismounting cleans, be connected by spiral helicine scalable wireway between described isolation type breathing mask and flowmeter, the isolation type breathing mask is connected by dismountable nut with wireway.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model isolation type compressed air self-help device.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of isolation type compressed air self-help apparatus, include the gas source connector 1 that connects in turn, pressure reducing regulator 2 and gas-liquid separator 3, the barometric damper 4 that the outlet of gas-liquid separator 3 connects in turn, flowmeter 5, wireway 6 and isolation type breathing mask 7, the barometric damper 4 that connects in turn wherein, flowmeter 5, wireway 6 and isolation type breathing mask 7 have five groups, all and be connected in the outlet of gas-liquid separator 3, also be connected with Pressure gauge 21 on the pressure reducing regulator 2, gas-liquid separator 3 bottoms are provided with a Draw off valve 31, isolation type breathing mask 7 is connected by dismountable nut 8 with wireway 6, the flexible in the shape of a spiral shape of wireway 6.
Gas source connector 1 is connected on the high-pressure air source, by pressure reducing regulator 2 and Pressure gauge 21 gases at high pressure are adjusted to suitable scope, post-decompression gas is by gas-liquid separator 3, liquid is discharged through Draw off valve 31, gas offers the wearer through each group barometric damper 4, flowmeter 5, wireway 6 and isolation type breathing mask 7, the atmosphere of malleation can avoid the wearer to take place to poison or suffocate, the wearer regulates barometric damper 4 separately and can reach the purpose of saving gas according to the indication of the flowmeter 5 tolerance demand in conjunction with self.
Under the normal condition, when isolation type breathing mask 7 dirty need cleanings, be separable wireway 6 and isolation type breathing mask 7 by dismounting nut 8, thus convenient the cleaning.
Barometric damper 4, flowmeter 5, wireway 6 and isolation type breathing mask 7 also can be set to three groups, six groups or other group numbers, and this all is to expect under the prerequisite of not paying creative work to those skilled in the art, repeats no more.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
