But anything has its dual character,Pipeline supply with coal gas gas product, offer convenience for resident with economical and practical in, due to its non-interruptible supplyFunction, once misoperation, be not singly loss problem, also can threaten people's life safely, have influence on social stability, rightThe harm of society is extremely serious. How observing under the prerequisite of thing law, making it better by the method for science is societyService benefits the people. For this reason, when coal gas natural-gas transfer pipeline in building is emitted to leakage, leak concentration predetermined value and detect, set up certainlyMoving report to the police and systemic-function automatic vent is disposed, pre-gas leakage prevention enters after air the problems such as phenomenon occurs to reveal when concentration raisesJust seem and be even more important.
At present, there is on the market house coal natural gas Leak Detection processed and warning device product, can monitor kitchen naturalGas leakage, arrives after certain value in concentration of natural gas, and detector part will be made a response in time, sends alarm signal, carriesAwake user processes as early as possible; Scientific worker to the outer coal gas natural gas line of building in the individual event aspect long defeated and short defeated pipe network monitoringResearch, also makes some progress. But, from entering gas pipeline that building start to the pipe entering beyond each floor userRoad emits leakage monitoring management, but rarely has people to study, and because this section of pipe network laid for resident uses gas, is difficult to from technological layerDistinguish the relation of resident family's use gas and pipeline gas leakage, together with this segment pipe replaces with inhabitation user, slightly problem occurs, and consequence willHardly imaginable. The solution of this problem will solve the intelligent whole process seamless connection of gas line network security protection from root.
