Refuge chamber door is used in the coal mine asylum cavern transition between room and living room. Protect the security of the adit indoor personnel (a set of two). Outward open, can waterproof, fire prevention, prevent shock wave effect.
Refuge chamber door has doors, door frames for the flat steel plate, steel plate and steel compound; Locking mechanism with double close lock; Use thrust ball bearing hinges, convenient to open.
In front of any interest security is always our top priority. When we are familiar with all emergency measures and precautions can minimize the risk coefficient.
Main Parameter
1,Before entering the refuge chamber, first through the fire door seal observation window to view the transition cave interior whether someone. If someone is scrubbing, scrubbing and so it ends into the chamber and close the survival survival chamber door, cave outside hedge personnel transition chamber and then open the door into the transition chamber for scrubbing.
2,Every time the number of gas cleaning should not be more than eight people.
3,Refuge chamber door Under normal operation condition, the CO auxiliary adit room door should be closed.
4,Using compressed air oxygen, there are 4 pressure adit indoor oxygen to wind export must be opened.
5,Use O2to supply oxygen,when O2sensor showed that O2concentration less than 18.5% or higher than 23%, can be slowly rotating knob to adjust the chamber of O2flow meter indoor concentration of O2.
6,When survival adit indoor concentration ofO2,CO and CO2to fulfill the requirements of human breath,O2 concentration is18.5%,CO concentration is less than24ppm,CO2 concentration is less tan 1%of the security,it is advisable to wear under the self-rescuer.
7,Under the condition of the damaged wind pressure, temperature control valve in the TCV - 1, 2, 3, 4, is always at least one in full open position. When survival adit indoor temperature, humidity, CO concentration,CO2 concentrations within the scope of security, according to actual situation to reduce the number of members of temperature control valve TCV - 1, 2, 3, 4.
8,When the CO2 pressure is less than 600PSI, filter integrated desiccant cooling Ge not operate properly installed, open the emergency gas control valve bypass system installed Ge extended running time.
9,When the indoor CO2 concentration can not survive cave below 1%, or color changes to light purple adsorbent, replace CO2 adsorbent
10,Groove identification shall identify the CO and the adsorbent, ensuring that the correct sorbent put Ge groove. Once CO adsorbent filling up Ge, do not replace or remove. When survival cave interior 24ppm CO concentration can not be reduced to below ,replacement CO adsorbent.
