Abstract
The invention discloses a pump body sealing part. The pump body sealing part comprises a center hole, bodies, circle center holes, convex bodies, radial convex bodies, top protrusions and bottom protrusions. The pump body sealing part is characterized in that the center hole is located between the two bodies, the circle center holes are formed in the bodies, the convex bodies are arranged on the bodies, the radial convex bodies are arranged on the bodies, the bottom protrusions are arranged at the bottoms of the radial convex bodies, and the top protrusions are arranged on the convex bodies. The pump body sealing part is simple in structure and convenient to operate, when the sealing part is installed in and abuts against an opening in the end face of a pump body, the direct junctures of the top protrusions and the bodies are prevented from directly making contact with the end face of the opening, the sealing part can be tightly matched with the opening of the pump body, and meanwhile the sealing effect is achieved through the bottom protrusions.
Description
Technical field
The present invention relates to sealed interface technical field, be specially a kind of pump housing Sealing.
Background technique
Sealing is anti-fluid or solid particle from leaking between adjacent junction plane and preventing introduced contaminants as the material of the component of the intrusion such as dust and moisture machinery equipment inside or part, its Performance Influence Factor of various sealing is different, as mechanical seal (packing seal etc.) influence factor has temperature, pressure etc. bears in medium, wearing and tearing, institute.
Summary of the invention
The object of the present invention is to provide a kind of pump housing Sealing, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technological scheme: a kind of pump housing Sealing, comprise center hole, body, circle center hole, convex body, radial convex body, top bump and bottom protrusion, it is characterized in that: described center hole is between two bodies, be provided with circle center hole in described body, described body is provided with convex body, and described body is also provided with radial convex body, be provided with bottom protrusion bottom described radial convex body, described convex body is equipped with top bump.
Preferably, the cross section of described bottom protrusion and top bump is circular.
Preferably, the cross section of described center hole is curved.
Preferably, described body is that pvc material is made.
Compared with prior art, the invention has the beneficial effects as follows: a kind of pump housing Sealing, structure is simple, easy to operate, when Sealing is encased in the opening of pump body end surface and offsets, top bump and the direct junction of body are avoided directly contacting with the end face of opening, make Sealing more can with the opening close-fitting of the pump housing, simultaneously bottom protrusion also plays the effect of sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, center hole, 2, body, 3, circle center hole, 4, convex body, 5, radial convex body, 6, top bump, 7, bottom protrusion.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the invention provides a kind of technological scheme: a kind of pump housing Sealing, comprise center hole 1, body 2, circle center hole 3, convex body 4, radial convex body 5, top bump 6 and bottom protrusion 7, it is characterized in that: described center hole 1 is between two bodies 2, be provided with circle center hole 3 in described body 2, described body 2 is provided with convex body 4, and described body 2 is also provided with radial convex body 5, be provided with bottom protrusion 7 bottom described radial convex body 5, described convex body 4 is equipped with top bump 6.
The cross section of described bottom protrusion 7 and top bump 6 is circular, and the cross section of described center hole 1 is curved, and described body 2 is made for pvc material.
Concrete usage mode: the present invention in use, when Sealing is encased in the opening of pump body end surface and offsets, top bump 6 and the direct junction of body 2 are avoided directly contacting with the end face of opening, make Sealing more can with the opening close-fitting of the pump housing, simultaneously bottom protrusion 7 also plays the effect of sealing.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
