Set on the anti-discouraged component 3 between gas source gas transmission port 2.Illustrate this programme below by specific embodiment.
Gas source gas transmission port includes existing gas cylinder or natural gas output end port etc., the other end root of air hose
Other use devices behind end, such as gas cooker are used according to demand connection.The concentration that anti-discouraged component 3 is leaked by detection gas
Or gas flow size realizes the transmission of cutting gas, prevents the generation of malignant event in time, it is also possible to carry out fuel gas pipeline system
The source of combustion gas is cut off when maintenance, debugging.
Embodiment one.
As shown in Fig. 2, anti-discouraged component 3 includes self-closing valve 31, the decompression between self-closing valve 31 and gas source gas transmission port 2
Valve 32；
31 input port of self-closing valve connects the output end of pressure reducing valve 32, and 31 output port of self-closing valve moulds crossover sub by steel
It is connect with 1 port of air hose；Connection between self-closing valve 31 and pressure reducing valve 32 can pass through double outer silks according to interface requirements
Connector connection or other quick couplings connection.
32 input terminal of pressure reducing valve is connect with gas source gas transmission port, the setting of pressure reducing valve 32 for manually adjust gas source and flow amount or
It acts on and closes gas source gas transmission port 2.
The self-closing shutdown gas source immediately when self-closing valve 31 detects gas overcurrent, superpressure, under-voltage, minor leakage, anti-gas transmission
Hose 1 hurt, fallen off, damaged by rats etc. causes gas leakage.
The present embodiment self-closing valve 31 is connect with the connecting interface of air hose 1 using steel modeling translation interface, and reduction artificially connects
Connection interface causes gas leakage.
Embodiment two.
As shown in figure 3, the present embodiment and the difference technology of embodiment one are: it further include gas leakage alarming device 33,
Gas leakage alarming device 33 is independent power supply device, when gas leakage alarming device 33 detects that gas concentration is more than threshold value
When, issue alarm.
Embodiment three.
