The tube wall of the public affairs pipe 20 is disposed with buffer layer 40, fireprotection layer 50 and rigid matter layer 60 from inside to outside；The material of the buffer layer 40
Matter is plastic cement；The fireprotection layer 50 is hard polyaminoester；The rigid matter layer 60 is glass reinforced plastic or perspex steel.First sealing ring
Material used in 30 is plastic cement.Material used in the cushion 23 is plastic cement or rubber.Material used in second sealing ring 70 is rubber
Glue.
In order to avoid the end face of public pipe 20 is damaged because of collision, public 20 threaded engagement of pipe is facilitated to be connected in main pipe 10, it should
The end face corner of public pipe 20 is set as keeping away an arc 27.
The course of work of the utility model embodiment are as follows: in the initial state, public pipe 20 is separated from each other with main pipe 10, described
Movable bulge loop 22 on public pipe 20 is slided under the rolling action of the elastic force and limited block 24 of spring 26 along accommodating chamber 25 is flexible
It is dynamic to protrude from accommodating chamber 25；When public pipe 20 is under manual operation, by mutually screwing for female line 11 and male line 21, so that public pipe 20
It is threaded into main pipe 10 therewith；After the movable bulge loop 22 on public pipe 20 touches main pipe 10, under the extruding of main pipe 10,
The activity bulge loop 22 will squeeze spring 26 and be contracted in accommodating chamber 25；When public 20 precession of pipe to movable 22 phase of bulge loop
When the position of the limit concave ring 12 of cooperation, the inner wall that movable bulge loop 22 is no longer influenced by main pipe 10 is squeezed, and the activity on public pipe 20 is convex
Ring 22 is connected in the limit along 25 movable telescopic of accommodating chamber under the rolling action of the elastic force and limited block 24 of spring 26
In concave ring 12, so that public pipe 20 is fixed in main pipe 10.
The present apparatus is mutually screwed under effect using female line 11 and male line 21, so that side of the male pipe 20 directed along female line 11
To screw be fixed to main pipe 10 on, on the one hand reduce docking pipe fitting usage amount, reduce cost, on the other hand avoid natural gas from
Clearance leakage between main pipe 10 and public pipe 20, achievees the purpose that once to prevent natural gas from leaking；Utilize movable bulge loop 22 and limit
Under the flexible mutual clamping effect of position concave ring 12, so that public pipe 20 and the fixation of main pipe 10 are further strengthened, prevent because of heat
Swollen shrinkage leads to the gap variation of public pipe 20 and main pipe 10 and natural gas is caused to permeate from gap, in conjunction with second sealing
Circle 70 is sheathed on movable bulge loop 22 to be leaked out to outside pipe from the movable bulge loop 22 to prevent natural gas, so that reaching secondary prevents
The purpose that natural gas leaks；The main pipe 10 is fixed on using the first sealing ring 30 and the intersection of public pipe 20 is natural for preventing
Gas leaks out to outside pipe, to achieve the purpose that prevent natural gas from leaking three times；Therefore, the utility model is provided with three from inside to outside
It is secondary to prevent natural gas from leaking structure, and work as hair there is certain overdose space of expanding with heat and contract with cold between public pipe 20 and main pipe 10
When phenomenon that heat is swollen, public pipe 20 will more be adjacent to and be fixed in main pipe 10, when shrinkage phenomenon occurs, public pipe 20 and main pipe 10
Gap will increase certain space, but since movable bulge loop 22 is connected in limit concave ring 12, and be arranged on movable bulge loop 22
Second sealing ring 70, so that natural gas be effectively prevent to infiltrate into outside pipe from public pipe 20 and the increased gap of main pipe 10；It solves
It solves existing natural gas line and causes what natural gas leaked to lack due to using pipe fitting connection in the biggish special area of the morning and evening temperature difference
It falls into, improves the whole performance for preventing natural gas from leaking；Also, since the outer surface of first sealing ring 30 is coated with solidification
Sealant 80 intersects bearing with public pipe 20 for the first sealing ring 30 to be fixed on the main pipe 10 to prevent gas permeation extremely
Pipe is outer, makes due to using pipe fitting connection to further overcome existing natural gas line in the biggish special area of the morning and evening temperature difference
The defect to leak at natural gas, to achieve the purpose that reinforce the sealed connection that is fixed to each other between firm natural gas line.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments in the case where not departing from this practical spirit or scope.Therefore, this is practical
