Abstract
The invention discloses a plugging device which comprises a cover plate and a projection. The projection is arranged in the middle of the cover plate, a plurality of mounting holes are annularly arrayed in the cover plate, a sealing groove is formed in the projection, and a plane between one side of the sealing groove and the end face of the projection is inclined, wherein the side is adjacent to the end face of the projection. In the use process of the plugging device, a sealing ring is sleeved in the sealing groove in the projection, the projection of the plugging device extends into a pipeline, the plugging device is fixedly mounted by the aid of the mounting holes in the cover plate, gas or liquid in the pipeline is effectively prevented from running out from the gap of the pipeline as the sealing ring is arranged between the pipeline and the plugging device, surrounding environments are guaranteed, and the service life of the plugging device is prolonged.
Description
Technical field
The present invention relates to a kind of shutoff, be specifically related to a kind of shutoff that is applied on the pipeline.
Background technique
Shutoff is a kind of component that play sealing process, in the process of using, stretches in the component of required effect with the protuberance of shutoff, and then the connected element by screw and so on, and the cover plate section of shutoff and the component that act on are fixed.Wherein be applied on the pipeline, gas or liquid are carried out the shutoff of sealing process, cover plate section in its shutoff is connected with pipeline by mounting hole, but the surface of contact between shutoff and the pipeline can leave certain gap, thereby so that the sealing effect of shutoff is poor, in the process of using, the gas that it seals or liquid can be run out of in its gap on a small quantity, the environment around not only having polluted; And the gas of running out of or liquid can cause to the contact opening of shutoff and pipeline certain corrosive action, reduces the working life of shutoff.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed to be applied in the shutoff on the pipeline.
Technical solution of the present invention is achieved in that a kind of shutoff, is comprised of cover plate section and protuberance, and described protuberance is arranged on the place, neutral position of cover plate section; Annular array has several mounting holes in the described cover plate section; Be provided with seal groove on the described protuberance, and the plane layout of described seal groove between the end face of a side of contiguous protuberance end face and protuberance becomes the inclined-plane.
Further, annular array has 6 mounting holes in the described cover plate section, and described mounting hole is arranged to counter sink.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described shutoff of the present invention program is in the process of using, seal groove inner sleeve on protuberance is loaded onto seal ring first, then the protuberance of shutoff is extend in the pipeline, install fixing with the mounting hole in the cover plate section again, owing to being provided with seal ring between pipeline and the shutoff, effectively avoided gas or liquid in the pipeline to run out of in its gap, the environment around both having ensured has prolonged again the working life of shutoff; Simultaneously the plane layout of described seal groove between the end face of a side of contiguous protuberance end face and protuberance becomes the inclined-plane, its seal ring installs in the process of seal groove of shutoff protuberance at cover, progressively enter from the inclined-plane, this has been convenient to ring set in the seal groove of shutoff protuberance.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of shutoff of the present invention;
Accompanying drawing 2 is the sectional view of shutoff of the present invention;
Wherein: 1, cover plate section; 2, protuberance; 3, mounting hole; 4, seal groove; 5, inclined-plane.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Shutoff of the present invention is in the process of using, seal groove 4 inner sleeves on protuberance 2 are loaded onto seal ring first, then the protuberance 2 of shutoff is extend in the pipeline, install fixing with the mounting hole 3 in the cover plate section 1 again, owing to being provided with seal ring between pipeline and the shutoff, effectively avoided gas or liquid in the pipeline to run out of in its gap, the environment around both having ensured has prolonged again the working life of shutoff; Simultaneously the plane layout of described seal groove 4 between the end face of a side of contiguous protuberance 2 end faces and protuberance 2 becomes inclined-plane 5, its seal ring installs in the process of seal groove 4 of shutoff protuberance 2 at cover, 5 progressively enter from the inclined-plane, and this has been convenient to ring set in the seal groove 4 of shutoff protuberance 2.
Wherein annular array has 6 mounting holes 3 in described cover plate section 1, and described mounting hole 3 is when being arranged to counter sink, and the using effect of shutoff is best.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a shutoff is comprised of cover plate section and protuberance, and described protuberance is arranged on the place, neutral position of cover plate section; Annular array has several mounting holes in the described cover plate section; It is characterized in that: be provided with seal groove on the described protuberance, and the plane layout of described seal groove between the end face of a side of contiguous protuberance end face and protuberance becomes the inclined-plane.
2. shutoff according to claim 1 is characterized in that: annular array has 6 mounting holes in the described cover plate section, and described mounting hole is arranged to counter sink.
