Product Introduction
Product Introduction
ZYJ compressed air self-help devices with decompression, flow control, silencers, discharge, dust and other functions, compact structure, easy to use, fast, when the coal mine gas exceeded, through this device provide fresh air to the staff, to avoid security the role of disaster.
Working principle
This device consists of piping, opening and closing valves, connecting tube, and protective sheath decompression group of five parts. When the coal mine gas concentration occurs when excessive or excessive signs, flip open and close valve handle gas path unobstructed, functional unit completed quickly draining, filtering, decompression and silencers and other action, this time filled with fresh air protection kit Escaping personnel for rescue breathing. Protective jacket of air pressure (0.05 ~ 0.1) Mpa, protective sleeve, toxic gases comprising a pressure lower than the pressure, so an external harmful gases will not enter the protective jacket for disaster prevention personnel hazard.
