Abstract
The utility model discloses a gas defense self-rescue respirator for miners. One-way exhaust valve and one-way inhalation valve that are connected to the outside via single-pass are set in the respirator; the single-pass one-way inhalation valve is connected to the duct; air sac is connected in the duct; gas collecting tube is set in the air sac. This utility model, with simple structure and no need for the oxide supply device, can directly inhale the air in the gas supply pipe and air supply pipe, so that the miner can, under the condition of gas leakage, inhale fresh air and escape in time, thus safeguarding the lives of miners.
Description
Technical field the utility model relates to a kind of mining gas defence self-rescue apparatus.
Background technology is present, because special-purpose gas mask selling at exorbitant prices, and it is heavy, many mines all do not have to be equipped with, though and many mines have all been laid the pipeline for pneumatic tools air feed and air feed pipe in the tunnel of exploitation, when gas leakage occurring, a lot of people are not owing to there is gas mask, add the air that to breathe air feed and air feed pipe, make its gas poisoning and die.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, provides a kind of simple in structure, and not aerobic air feed system can directly suck the respirator for gas defence of air in the pipeline of air feed and air feed pipe.
The technical solution of the utility model is as follows: a kind of mining gas defence self-rescue apparatus, respirator are provided with and the one-way exhaust valve of outside single-pass and the one-way sucting valve of single-pass; The one-way sucting valve of single-pass links to each other with conduit; Also be connected with air bag on conduit, air bag is provided with discharge.Air bag is breathed for the people by the air of discharge collection ventilation shaft; The gas of breathing out discharges by the one-way exhaust valve with outside single-pass, and this valve ends when air-breathing; One-way sucting valve can suck the air in the air bag, but the gas of breathing out can not enter air bag.
Described discharge is provided with check valve.This valve behind the air of collection ventilation shaft is because the automatic cut-off of air bag pressure inside can not be rushed down air outward.
Described conduit is provided with flow control valve, can regulate air demand according to individual human needs.
Described respirator is provided with nasal obstruction or nose clip, prevents that pernicious gas from being entered by nasal cavity.
Described air bag is the clothes that have interlayer, uses convenient.Certain described air bag can also be arranged to other Any shape.
A kind of mining gas defence self-rescue apparatus of the present utility model is simple in structure, not aerobic air feed system can directly suck air in the pipeline of air feed and air feed pipe, makes the miner can suck air when gas leakage, have enough escape time, ensure miner's life.
Appended drawings is a structural representation of the present utility model
The specific embodiment is as shown in drawings:
A kind of mining gas defence self-rescue apparatus, respirator 1 are provided with and the one-way exhaust valve 5 of outside single-pass and the one-way sucting valve 6 of single-pass; The one-way sucting valve 6 of single-pass links to each other with conduit 2; Also be connected with air bag 3 on conduit 2, air bag 3 is provided with discharge 4.
Described discharge 4 is provided with check valve 7.
Described conduit 2 is provided with flow control valve 8.
Described respirator 1 is provided with nasal obstruction or nose clip 9.
Described air bag 3 is for having the clothes of interlayer.
When gas leakage occurring, respirator 1 is contained in the mouth, the discharge 4 that is provided with air bag 3 is gathered the air of ventilation shafts, breathes for the people.Discharge 4 is provided with check valve 7 can not rush down air outward, and the people can be escaped, and gathers once more after the air in the air bag 3 uses up.Air bag 3 makes on one's body clothes can be through, the escape of being more convenient for.
