Security responsibilities for the day, life is paramount, Shandong one hundred million coal, so that the integrity everywhere
FFQ gas pipeline anti-tempering back gas means is a method for preventing flashback and combustion of coal mine gas pipeline explosion, a special device preventing the return air, but also has anti-return function is to prevent tempering device upgrade products.
FFQ gas pipeline gas device anti-tempering back together and blow-gas drainage and utilization systems belong to the necessary safety equipment is suitable for installation in gas output tube system, usually installed in locations away from the user, or the gas pump close of play mine protection up and down, drainage pumping stations and user safety.
Second, the principle:
FFQ gas pipeline anti-tempering back gas installations simple structure, safe and reliable operation of pumping gas in the course of their work, the cover means at the gas pressure within the open, in normal working condition; when no gas gas delivery, the apparatus cover In the counterweight lever force pressing mouth into the trachea, which prevents gas loopback; same time, when the explosion occurred, the apparatus is also pressed into the trachea mouth cover, the pressure can be explosion-proof sheet red open, in order to achieve relief the purpose of proof, thus effectively protect Inoue underground, drainage pumping station equipment and user safety.
