Description
Technical field
The present invention relates to a kind of municipal fuel gas conduits.
Background technique
Fuel gas conduit is a kind of combustion gas pipe special.Replace traditional snap rubber soft with metallic gas pipe hose
Pipe.PE fuel gas conduit is in the municipal tubing market of China, and plastic conduit is just in stable development, PE fuel gas conduit, PP-R fuel gas conduit, UPVC
Fuel gas conduit all occupies a tiny space, and wherein PE manages powerful growth momentum and attracts people's attention the most, also very wide using field
It is general.When gas pipeline engineering, to avoid by tube body weld seam, towards metope, the unconspicuous pipeline of weld seam should mark in advance.It applies
The installation of the copper pipe or corrugated stainless steel tubing that are located in pipe shaft carries out after pipeline construction, in Pipeline Crossing Program vertical shaft
Jacketed pipe is answered when partition panel, there should be the spacing not less than 5mm between casing and pipeline.The combustion gas copper pipe or stainless steel ripple secretly buried
Guan Buying is in contact with various metals and electric wire；When that can not avoid, separated using insulating materials.Gas pipeline passing through floors
Hole successively vertically determines lower layer's hole location preferably from top downward drilling with weight；Not because of upper layer and lower layer's wall wall thickness
With and when can not fall in a line, preferably make that second word is curved to be allowed to avoid being turned to pipe fitting by wall.Interior is bright to set gas pipeline and its pipeline
The japanning of attachment should carry out after examining real pressing lattice；When using steel-pipe welding, it should be applied after derusting (see metallic luster)
Paint: first by whole commissure brush twice anti-corrosive primers, then in comprehensive brushing twice anti-corrosive primer and twice finishing coat；Using zinc-plated
When steel tube screw thread connects, one of anti-corrosive primer should be first brushed after the installation of remaining pipe fitting junction, then comprehensive brushing twice finishing coat again.
Current existing fuel gas conduit structural strength is not high, and heat insulation is bad, can not discharge the electrostatic of pipeline.
Summary of the invention
It is high that the technical problem to be solved in the present invention is to provide a kind of structural strengths, and good heat-insulation effect can discharge pipeline
The municipal fuel gas conduit of electrostatic.
To solve the above problems, the present invention adopts the following technical scheme: a kind of municipal administration fuel gas conduit, including polyfluortetraethylene pipe
Layer, HDPE layer, glass layer and two clips, the polytetrafluoroethylene (PTFE) tube layer, HDPE layer, glass layer and clip are successively
It is arranged from the inside to the outside, arc convex is provided in the polytetrafluoroethylene (PTFE) tube layer, the clip both ends are equipped with bending part in horizontal,
Fixing bolt is installed on the bending part, rock wool layer is filled on the outside of the clip, is provided on the outside of the rock wool layer stainless
Steel layer, the clip outside are provided with arc-shaped elastic slice, and the stainless steel layer bottom is provided with metal wire and conducting rod, described
Conducting rod passes through metal wire and clamp connection.
Preferably, the elastic slice both ends are welded with clip respectively, keep elastic slice that can be firmly installed on clip, when
When receiving external force extruding, elastic slice can be deformed, and play pooling feature.
Preferably, the metal wire both ends are welded with clip and conducting rod respectively, metal wire passes through stainless steel layer and rock
Cotton layer, stainless steel layer and the drilling of rock wool layer corresponding position.
Preferably, the tapered setting of conducting rod, conducting rod using when be inserted in ground end.
Preferably, the stainless steel layer thickness is greater than 3mm, stainless steel layer is able to ascend structural strength.
The invention has the benefit that the clip of setting makes polytetrafluoroethylene (PTFE) tube layer, HDPE layer, glass layer connection
Compact, so that stable structure, stainless steel layer is able to maintain structural strength height, and elastic slice has pooling feature；The rock wool layer of setting and
Glass layer has heat insulating function；The metal wire both ends of setting are welded with clip and conducting rod respectively, can make conducting rod
Discharge the electrostatic that pipeline generates.
Detailed description of the invention
Fig. 1 is a kind of structure chart of municipal fuel gas conduit of the present invention.
Specific embodiment
As shown in Figure 1, a kind of municipal administration fuel gas conduit, including polytetrafluoroethylene (PTFE) tube layer 1, HDPE layer 2, glass layer 3 and two
A clip 4, the polytetrafluoroethylene (PTFE) tube layer 1, HDPE layer 2, glass layer 3 and clip 4 are successively arranged from the inside to the outside, described poly-
It is provided with arc convex 5 in tetrafluoroethene tube layer 1, arc convex 5 and 1 integrated injection molding of polytetrafluoroethylene (PTFE) tube layer, it can be with
The structural strength of polytetrafluoroethylene (PTFE) tube layer 1 is promoted, 4 both ends of clip are equipped with bending part 6 in horizontal, pacify on the bending part 6
Equipped with fixing bolt 7, fixing bolt 7 can pass through the bending part 6 of two clips 4, so that two clips 4 are completely embedded, it is described
It is filled with rock wool layer 8 on the outside of clip 4, is provided with stainless steel layer 9 on the outside of the rock wool layer 8, is provided on the outside of the clip 4 in arc
The elastic slice 10 of shape, 9 bottom of stainless steel layer are provided with metal wire 11 and conducting rod 12, and the conducting rod 12 passes through metal wire 11
It is connect with clip 4.
It is welded respectively with clip 4 at 10 both ends of elastic slice.It is welded respectively with clip 4 and conducting rod 12 at 11 both ends of metal wire
It connects.The tapered setting of the conducting rod 12.9 thickness of stainless steel layer is greater than 3mm.
The invention has the benefit that the clip of setting makes polytetrafluoroethylene (PTFE) tube layer, HDPE layer, glass layer connection
Compact, so that stable structure, stainless steel layer is able to maintain structural strength height, and elastic slice has pooling feature；The rock wool layer of setting and
Glass layer has heat insulating function；The metal wire both ends of setting are welded with clip and conducting rod respectively, can make conducting rod
Discharge the electrostatic that pipeline generates.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.
