In figure：1 dust-proof lid, 2 dust-proof plugs, 3 rise to card convex, and 4 support clamp flange, 5 dust-proof outer walls, 6 rubber encloseds, 601
Rubber enclosed fixing end, 602 rubber enclosed free ends, 7 natural gas tubes.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
Referring to Fig. 1-2, wherein Fig. 1 is the dust-proof lid that prior art is also in the utility model embodiment, and this practicality is new
Type embodiment provides a kind of Gas Pipe dust cap, including rounded dust-proof lid 1, and the dust-proof lid 1 is by dust-proof plug
2nd, the card convex of supporting on the dust-proof periphery of plug 2 plays 3, supports clamp flange 4 and positioned to card positioned at the dust-proof outer edge of plug 2
The dust-proof outer wall 5 of the edge of flange 4 is constituted, wherein, rubber enclosed 6, rubber peel are fixed with by glue at the edge of dust-proof outer wall 5
The part that circle 6 is fixed on the 5 of dust-proof cover outer wall is rubber enclosed fixing end 601, and the other end of rubber enclosed 6 is rubber enclosed
Free end 602, wherein rubber enclosed free end 602 are less than because not receiving external force extension effect, its diameter in its natural state
The diameter 601 of rubber enclosed fixing end, concrete condition is shown in Fig. 2.
In order that rubber enclosed 6 has preferable tensile property, while can make rubber enclosed free end 602 in dust-proof outer wall
5 both sides are artificially overturn, and such as Fig. 3 is the installation of the situation, for convenience dust cap after upset, in a pre-installation on dust cap
Rubber enclosed 6 is by artificially being overturn, when mounted, and dust-proof lid is first arranged on to the end of natural gas tube 7, then passed through
It is artificial just to complete to install to be allowed to Fig. 4 such as being flipped back to by rubber enclosed free end 602, after installing, rubber enclosed free end
602 are closely fitted in natural gas tube surface in the presence of autogenous shrinkage power.In order to improve rubber enclosed free end natural
The adhesive force on tracheae surface, the inside surface roughness of the rubber enclosed 6 is less than 0.2Ra, rubber enclosed inner surface it is more smooth its
Vacuum with natural gas tube faying face is better, can provide a kind of micro-vacuum environment, is allowed to the attachment in natural gas tube surfaces
Power increases.Simultaneously for the natural gas tube of different tube diameters, the length of its rubber enclosed free end 602 is progress in the range of 3-20cm
Selection.Dust-proof lid 1 described in the present embodiment comes off during transport or construction etc., and in the work of rubber enclosed 6
Can still be played a part of blocking tubing with lower its, unless the dust-proof lid 1 that comes off depart from tubing rear-mounted on rubber enclosed because
Constantly rubber enclosed 6 is also pulled away from tube surfaces by shake, and pulling force then necessary mitigation is trembled in order to reduce the top of dust-proof lid 1
The weight of dust-proof lid 1, therefore needed in the design of dust-proof lid 1 to being balanced between its weight and quality, it is described anti-
Dirt lid 1 is made up of one of PE, PVC, PPR material.
The utility model in dust cap by rubber enclosed 6 of the edge of existing dust-proof lid 1 plus shrinkage, consolidating
Reused when being scheduled on 7 end of natural gas tube and be fixed on rubber enclosed 6 on dust-proof lid 1 and be enclosed on the road end outer wall of natural gas tube 7,
The wherein more big then fixation of swell increment of the rubber enclosed 6 after being enclosed on tubing is more firm；Secondly by by the inwall of rubber enclosed 6
Smoothness is improved, and is conducive to improving rubber enclosed 6 in the compactness on the surface of natural gas tube 7, the two forms one kind on the contact surface
Micro-vacuum state, further improves frictional resistance therebetween.
Principle of the present utility model be exactly using the clamping force of dust-proof lid 1 and the convergent force of rubber enclosed 6 be combined come
Dust-proof lid 1 is fixed on natural gas tube end, occur dust-proof lid 1 during transport, storage etc. and depart from tubing end
Portion is also not in that dust cap integrally departs from.
Embodiment of the present utility model described above, does not constitute the limitation to the utility model protection domain,
Any various other corresponding changes and deformation according to made by technical concept of the present utility model, should be included in this practicality
In new scope of the claims.
