Abstract
The utility model discloses a kind of natural gas line cover of dust, its dustproof lid comprises dustproof plug, and dustproof plug periphery setting is supported card convex and risen, and card convex edge is supported in the rearward end setting of dustproof plug.When work, dustproof plug is embedded in the through hole at natural gas line both ends, and supporting card convex rises and the inwall butt of natural gas line both ends through hole, the card effect of supporting plaing by supporting card convex, in transport, handling process, the utility model is difficult for dropping, and then ensures dustproof reliability and stability; In addition, support the both ends of the surface butt of card convex edge and natural gas line, support card convex edge and can play position-limiting action and can facilitate the utility model to take out in the through hole at natural gas line both ends, support card convex edge and can also prevent that dust from entering in natural gas line via the gap between dustproof plug and through-hole wall.So, the utlity model has structure design novelty, good dustproof effect and advantage easy to use.
Description
Technical field
The utility model relates to dust keeper technical field, relates in particular to a kind of natural gas line cover of dust.
Background technology
For natural gas line production firm, in order to avoid natural gas line finished product, depositing, in transportation, extraneous pollutants enters to the inside of natural gas line, deposit at natural gas line, in transportation, must prevent dust by corresponding dust keeper in the both ends of natural gas line.
In prior art, also have the dust-proof cover device for shutoff natural gas line both ends, but in Natural Gas Pipeline Transportation, handling process, existing dust-proof cover device is easy to drop, dust-proof effect is had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is to provide a kind of natural gas line cover of dust for the deficiencies in the prior art, this natural gas line dustproof cover structure modern design, good dustproof effect and be difficult for dropping.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of natural gas line cover of dust, include the dustproof lid of rounded shape, dustproof lid includes the dustproof plug that is cylindrical shape, the periphery of dustproof plug be provided with at least three be circumference ring-type evenly the spaced apart card convex of supporting rise, support card convex and rise with dustproof plug first body formedly, the rear end side of the rearward end of dustproof plug in supporting card convex is provided with along dustproof plug radial outward extends and is the circular card convex edge that supports.
Wherein, the described outer side edges edge of supporting card convex edge is provided with along the axis direction of described dustproof plug and the dustproof outer wall extending forward.
Wherein, described dustproof plug, described one-body molded to card convex edge and described dustproof outer wall, described dustproof lid is the dustproof lid of PE.
The beneficial effects of the utility model are: a kind of natural gas line cover of dust described in the utility model, its dustproof lid comprises dustproof plug, dustproof at least three of plug periphery settings are the even spaced apart card convex of supporting of circumference ring-type and rise, and card convex edge is supported in the rear end side setting of the rearward end of dustproof plug in supporting card convex.When work, dustproof plug is embedded in the through hole at natural gas line both ends, and the card convex of supporting of dustproof plug periphery wall rises and the inwall butt of natural gas line both ends through hole, the card effect of supporting plaing by supporting card convex, in transport, handling process, the utility model is difficult for dropping, and then has effectively ensured dustproof reliability and stability; In the time that dustproof plug is embedded in the through hole at natural gas line both ends completely, support the both ends of the surface butt of card convex edge and natural gas line, support card convex edge and can play position-limiting action and can facilitate the utility model to take out in the through hole at natural gas line both ends, support card convex edge and can also prevent that dust from entering in natural gas line via the gap between dustproof plug and through-hole wall.Comprehensive above-mentioned situation is known, the utlity model has structure design novelty, good dustproof effect and advantage easy to use.

Detailed description of the invention
Below in conjunction with concrete embodiment, the utility model is described.
As depicted in figs. 1 and 2, a kind of natural gas line cover of dust, include the dustproof lid 1 of rounded shape, dustproof lid 1 includes the dustproof plug 2 that is cylindrical shape, the periphery of dustproof plug 2 be provided with at least three be circumference ring-type evenly the spaced apart card convex of supporting play 3, support card convex and rise 3 one-body moldedly with dustproof plug 2, the rearward end of dustproof plug 2 rear end side of 3 in supporting card convex is provided with along dustproof plug 2 radial outward extends and is the circular card convex edge 4 that supports.
In the utility model working process, dustproof plug 2 is embedded in the through hole at natural gas line both ends, and dustproof plug 2 periphery walls support card convex rise 3 with the inwall butt of natural gas line both ends through hole, play 3 the card effect of supporting by supporting card convex, in transport, handling process, the utility model is difficult for dropping, and then has effectively ensured dustproof reliability and stability.
In addition, in the time that dustproof plug 2 is embedded in the through hole at natural gas line both ends completely, support the both ends of the surface butt of card convex edge 4 and natural gas line; Wherein, support card convex edge 4 and can play position-limiting action on the one hand, can facilitate on the other hand the utility model to take out in the through hole at natural gas line both ends, support card convex edge 4 and can also prevent that dust from entering in natural gas line via the gap between dustproof plug 2 and through-hole wall.
Need further point out, dustproof lid 1 of the present utility model can adopt PE material integrated injection molding to form, i.e. dustproof plug 2, one-body molded to card convex edge 4 and dustproof outer wall 5, and dustproof lid 1 is the dustproof lid 1 of PE; Certainly, said structure form does not form restriction of the present utility model, wherein, dustproof lid 1 of the present utility model can also adopt split-type structural design, be about to dustproof plug 2, support card convex rise 3 and dustproof outer wall 5 be designed to absolute construction, and interconnective two parts can be realized assembly connection by the mode such as be spirally connected.
Comprehensive above-mentioned situation is known, the utlity model has structure design novelty, good dustproof effect and advantage easy to use.
As shown in Figure 3 and Figure 4, be provided with along the dustproof outer wall 5 that prevents dust the axis direction of plug 2 and extend forward to the outer side edges edge of card convex edge 4.In the time that dustproof plug 2 of the present utility model is embedded in the through hole at natural gas line both ends completely, dustproof outer wall 5 fits over the periphery at natural gas line both ends, and these dustproof outer wall 5 structure designs can improve dust-proof effect of the present utility model further.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
