The flange of adjacent two natural gas lines all installs protecting cover outward, when there is natural gas leaking in two gas pipeline joints, the rock gas leaked can be full of air storing cavity in very short time, air storing cavity sealing better, thus cause the pressure in air storing cavity to raise, after pressure transducer detects that air storing cavity pressure raises, alarm sends warning, inductive resistance simultaneously in catalytic combustion sensor and rock gas generation flameless combustion, break bridge balance, output signal to alarm, adopt the sensor that two kinds different, as long as wherein any one sensor sends signal transmission to alarm, alarm can be reported to the police, stability is higher, the position that alarm sends warning is exactly the position that natural gas line joint occurs to leak, very short to the time lag sending warning from natural gas leaking, overhaul more quick and convenient.
As preferably, the outside of described natural gas line is arranged with silicone tube, the two ends of described silicone tube extend to form connecting sleeve respectively, and the end of described connecting sleeve is stretched in air storing cavity, and the inner ring of the outside of described connecting sleeve and upper protecting cover, lower protecting cover is tightly connected.Natural gas line is arranged in kitchen, and the oil smoke in kitchen is heavier, has corrosivity to natural gas line, and silicone tube plays a protective role to natural gas line, prevents natural gas line from leaking gas because of corrosion.
As preferably, be provided with annular space between described silicone tube and natural gas line, the two ends of annular space are sealed by connecting sleeve, and the connecting sleeve of one of them is provided with some attachment holes for connecting annular space and air storing cavity.Time on the tube wall occurring in natural gas line when leaking gas, the rock gas leaked enters annular space, and enter in air storing cavity by attachment hole, pressure transducer, catalytic combustion sensor produce signal transmission and send warning to alarm, annular space outside a natural gas line is only communicated with one of them air storing cavity of end, namely when alarm occurs to report to the police, the flange that warning here is just described and this section of natural gas line be communicated with air storing cavity leak gas, maintainer finds natural gas leaking place fast according to alert locations, improves overhaul efficiency.
As preferably, the both sides of described upper protecting cover are respectively equipped with through hole, the outside of pressure transducer, catalytic combustion sensor is provided with clamping cover, the outer end of clamping cover is provided with stud, the outer end of stud to be stretched out from through hole upper separation sleeve and is passed through nut check, described center stud is provided with threading hole, and the datawire in pressure transducer, catalytic combustion sensor passes and is connected with alarm from threading hole.This kind of connection can prevent the datawire of pressure transducer, catalytic combustion sensor from leaking gas through the place of upper protecting cover.
Therefore, the utility model has when natural gas leaking, and alarm can send warning, highly sensitive beneficial effect within the extremely short time, is especially applicable to indoor use, greatly improves the usage safety performance of pipe natural gas.
