High-grade energy is needed through Pipeline transport after being exploited to treatment plant, then passes through Pipeline transport to ten thousand ten thousand families.Defeated
During sending, due to a pipeline not instead of entirety, it is made of the splicing of multiple pipes, due to bear internal larger pressure
Power, and external environmental damage, thus it is very high to the sealing requirements of junction.After pipe laying operation, need periodically
Be detected investigation, to find leakage point, repair in time, prevent larger accident and occur.Since the pipeline overwhelming majority is spread
It is located at field, existing detection mode is detected close to tie point using portable detector.Due to external rings
Border space is big, slight leakage, and the dilution that can be flowed with this air reduces testing result numerical value, causes detection inaccurate, is easy
It omits, hidden danger cannot exclude in time, abnormally dangerous.

To achieve the above object, the utility model provides the following technical solutions：A kind of gas for natural gas line is examined
Device is surveyed, including is fixed on the seal closure of pipeline junction and for detecting leaked gas detector, seal closure includes upper
Seal closure and lower seal closure, upper seal closure and lower seal closure are semiorbicular shell structure, upper seal closure and lower seal closure
Both ends are both provided with extension overlap, and are sticked to form an entirety by extension overlap, and bolt assembly is provided on extension overlap.
Detection cylinder is provided on upper seal closure, the inductive probe of detector is plugged on by detecting cylinder inside seal closure.
As a kind of preferred technical solution of the utility model, the both ends of lower seal closure are provided with upper seal closure junction
Adhesive piece, the both ends of upper seal closure and lower seal closure junction are provided with groove corresponding with the adhesive piece.
As a kind of preferred technical solution of the utility model, both sides and the pipeline junction of seal closure are provided with raised knot
