The utility model is realized by adopting the following technical scheme:
a protection device for a natural gas pipeline with an unconventional laying path comprises the natural gas pipeline which is positioned at a stair platform and passes through the unconventional laying path, a pipe culvert is arranged along the unconventional laying path of the natural gas pipeline, and the two ends of the pipe culvert are tightly packed by adopting a flexible anti-corrosion waterproof material and then the unconventional laying section of the natural gas pipeline is hermetically coated; a plurality of combustible gas detectors are arranged in the pipe culvert and are connected with an explosion-proof natural gas leakage alarm control cabinet positioned in a staircase through a sensing line; the natural gas pipeline is characterized in that a gas emergency cut-off valve and a flange ball valve are arranged on a conventional laying section of the natural gas pipeline, and the gas emergency cut-off valve is connected with an explosion-proof natural gas leakage alarm control cabinet located in a staircase through a sensing circuit.
When the device is used, the protection monitoring is provided for the gas supply of a natural gas low-pressure (below 3 KPa) user, a pipe culvert which can be installed on site and both ends of which are filled with flexible anti-corrosion and waterproof materials is built for a natural gas pipeline of an abnormal laying path, a combustible gas detector is installed in the closed pipe culvert space, and an independent ventilation space is provided by utilizing the characteristics of good corrosion resistance, pressure resistance, strong sealing property and the like of the pipe culvert. In case of leakage of a gas pipeline laid in an abnormal path, the outer wall of a pipe culvert of the device is firstly sealed without leakage and without influencing the normal use of the stairs; meanwhile, the combustible gas detector can rapidly detect gas for warning due to the small space of the pipe culvert, signals are sent to the natural gas leakage alarm control cabinet through the sensing line, the natural gas leakage alarm control cabinet sends instructions to the gas emergency cut-off valve through the sensing line to perform emergency cut-off action, and then the flange ball valve is manually cut off to ensure the safety of later maintenance.
The utility model has the following advantages:
1) and the gas pipeline can be wrapped on site without sleeving the whole pipe, and the gas pipeline welded by the pipe fitting can be wrapped.
2) The pipe culvert has the characteristics of attractiveness, moisture resistance, corrosion resistance and sealing, and can effectively reduce the waste of physical space.
3) The utility model has simple structure, convenient installation, low price, safety, effectiveness and wider application range.
The utility model has reasonable design, and the protection device provided by the natural gas pipeline with the unconventional laying path is particularly a protection device which effectively protects the natural gas pipeline when the natural gas pipeline is in an abnormal laying path and a welded junction is needed.
