Problems solved by technology

[0002] At present, the global coal industry attaches great importance to safe production. Most of the coal mines in my country are mines with high gas. It is required to eliminate the filter self-rescuer and replace it with an isolated self-rescuer. At the same time, it is required to be equipped with a safety cabin; The traditional breathing valve seat of the isolated self-rescuer is a kind of leakage valve seat. Its main function is to open the leakage valve when the air pressure in the airbag reaches a certain Part of the excess oxygen is discharged to reduce the pressure of the airbag, which causes waste and shortens the protection time

Abstract

The invention relates to a compound type self-rescuer, which belongs to the technical field of self-rescuers under coal mine. The technical problem required to be solved is to provide the compound type self-rescuer which integrates a filter type self-rescuer and an isolated type self-rescuer, and can not result in waste. The compound type self-rescuer adopts the technical scheme that: the structure of a tee coupling is that three tubular ports are connected onto a hollow sphere, a change-over valve is arranged in the hollow sphere of the tee coupling, a mouth utensil is connected onto one port of the tee coupling, a filter respirator is connected onto the other port of the tee coupling, an air bag is connected onto the last port of the tee coupling through a connector, and the connector is arranged in the air bag. The compound type self-rescuer provided by the invention is changed over through the change-over valve, so that waste can not be caused, and the protective time is prolonged.

Description

technical field [0001] The composite self-rescuer of the invention belongs to the technical field of underground self-rescuers in coal mines. Background technique [0002] At present, the global coal industry attaches great importance to safe production. Most of the coal mines in my country are mines with high gas. It is required to eliminate the filter self-rescuer and replace it with an isolated self-rescuer. At the same time, it is required to be equipped with a safety cabin; The traditional breathing valve seat of the isolated self-rescuer is a kind of leakage valve seat. Its main function is to open the leakage valve when the air pressure in the airbag reaches a certain Part of the excess oxygen is discharged to reduce the pressure of the airbag, which causes waste and shortens the protection time. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and the technical problem to be solved is to provide a composite self-rescuer w...
