ZYJ type wind pressure self rescue device for having an economic type of coal and gas outburst coal mine personnel rescue permanent rescue equipment.
Wind pressure self rescue device has the advantages of simple structure, convenient installation, easy maintenance features.
Z -- device
YJ -- air pressure self-help
Two, the work principle and structure feature
The 1 main structure
ZY type wind pressure self rescue device is mainly composed of an air inlet valve, throttling device, filter silencer, defending head cover.
The 2 Principle
Open the air intake valve device of the self, from connected to a compressed air compressed air system through the throttle decompression device, decompression after silencing filter silencer filter into the protective hood, provide separate fresh positive pressure air supply system and isolated from the environment polluted air for the persons in disaster in the protective hood.
