Abstract
The utility model relates to a double-pipeline emergency self saving system which belongs to safety articles of a coal mine. The utility model is composed of a first flange (2), a second flange (14), a first quick joint (12), a second quick joint (13), an air supplying valve (9), a flowrate control valve (7), etc. The utility model is provided with bifilar wind transporting pipelines, one bifilar wind transporting pipeline is an air pressure wind entering pipeline (16), and the other bifilar wind transporting pipeline is an exhausting pipeline (1). The double-pipeline emergency self saving system is suitable for emergency self saving when oxygen-free accidents appear caused by that a tunneling tunnel of the coal mine in complicated geological areas collapses and overflows, tunneling personnel's life safety is ensured, and time is gained for outside risk elimination and rescue.
Description
Technical field
The utility model belongs to the safety of coal mines articles for use, particularly a kind of dual circuit emergency self-saving system.
Technical background
The coal mine roadway driving face that does not contain or contain trace harmful gases in the complicated geological zone, because of not forming permanent support or influenced by other factors, exist the tunnel and emit danger because of country rock collapses in a big way, driving face is become stop the anaerobic space that air is supplied, in case have an accident, owing to reasons such as the tunnel angle are big, the rescue speed of getting rid of the danger will be affected, and be easy to cause casualties.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of easy to use, can be to the dual circuit emergency self-saving system of the digging laneway scene of the accident, colliery enclosure space oxygen supply for a long time.
The technical scheme that the utility model technical solution problem adopts is: dual circuit emergency self-saving system mainly is made up of flange, snap joint, air-supplying valve and flow control valve etc., be characterized in that it is provided with two-wire wind conveying pipe road, article one, be the air inlet air line, rapid fire stream union fixedly is housed on air inlet air line air feed side, an end of fixedly connected fast jet pipe on the joint, air-supplying valve and snap joint are equipped with in air-out termination at the air inlet air line, and snap joint connects decompression feeder and uncovered shape gas outlet; Another is a gas exhaust piping, and the gas exhaust piping outlet side connects the little negative pressure generator of rapid fire, and little negative pressure generator one side of rapid fire is connected with fast jet pipe with gas exhaust piping, and opposite side is an escape pipe.
The beneficial effects of the utility model are: dual circuit emergency self-saving system is applicable to that colliery, complicated geological zone digging laneway collapses and emits emergency self-saving when the anaerobic accident occurring, the driving workman can be connected with driving face end air inlet pipeline the decompression feeder with snap joint, open air-supplying valve, can be to the oxygen supply for a long time of accident confined space, waste gas is via gas exhaust piping and the little negative pressure generating device of rapid fire, discharge from the gas exhaust piping gas outlet, guarantee driving personnel's life security, getting rid of the danger to rescue to the outside gains time.
