Abstract
The utility model discloses a kind of new-type natural gas line cover of dust, its dustproof lid comprises dustproof plug, and card convex edge is supported in the rearward end setting of dustproof plug, and dustproof plug is with one-body molded to card convex edge.When work, dustproof plug is embedded in the through hole at natural gas line both ends, and the periphery wall of dustproof plug contacts with the inwall of natural gas line both ends through hole, because dustproof plug stretches in the through hole at natural gas line both ends, in transport, handling process, the utility model is difficult for dropping, and then has effectively ensured dustproof reliability and stability; 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 new-type 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 new-type natural gas line cover of dust for the deficiencies in the prior art, this new-type 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 new-type natural gas line cover of dust, include the dustproof lid of rounded shape, dustproof lid includes the dustproof plug that is cylindrical shape, the rearward end of dustproof plug is provided with along dustproof plug radial outward extends and is the circular card convex edge that supports, and dustproof plug is with to support card convex edge one-body molded.
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: the new-type natural gas line cover of dust of one described in the utility model, and its dustproof lid comprises dustproof plug, and card convex edge is supported in the rearward end setting of dustproof plug, and dustproof plug is with one-body molded to card convex edge.When work, dustproof plug is embedded in the through hole at natural gas line both ends, and the periphery wall of dustproof plug contacts with the inwall of natural gas line both ends through hole, because dustproof plug stretches in the through hole at natural gas line both ends, in transport, handling process, the utility model is difficult for dropping, and then has effectively ensured dustproof reliability and stability; 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.
Brief description of the drawings
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation at another visual angle of the utility model.
Fig. 3 is the structural representation of the utility model the second embodiment.
Fig. 4 is the structural representation at another visual angle of the utility model the second embodiment.
In Fig. 1 to Fig. 4, include:
1---dustproof lid 2---dustproof plug
3---supporting card convex edge 4---dustproof outer wall.
Detailed description of the invention
Below in conjunction with concrete embodiment, the utility model is described.
As depicted in figs. 1 and 2, include the dustproof lid 1 of rounded shape, dustproof lid 1 includes the dustproof plug 2 that is cylindrical shape, and the rearward end of dustproof plug 2 is provided with along dustproof plug 2 radial outward extends and is the circular card convex edge 3 that supports, and dustproof plug 2 is with to support card convex edge 3 one-body molded.
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 contact with the inwall of natural gas line both ends through hole, because dustproof plug 2 is inserted in the through hole at natural gas line both ends, 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 3 and natural gas line; Wherein, support card convex edge 3 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 3 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 3 and dustproof outer wall 4, 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 and dustproof outer wall 4 and 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 4 that prevents dust the axis direction of plug 2 and extend forward to the outer side edges edge of card convex edge 3.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 4 fits over the periphery at natural gas line both ends, and these dustproof outer wall 4 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.
