Abstract
The utility model relates to a novel cast sealing ring characterized by comprising a plurality of equant arcs, wherein two sides of each equant arc are respectively provided with a groove and a protrusion which are matched with each other. The sealing ring is divided into a plurality of independent parts and spliced in a reasonable splicing way. Sealing glue is filled, so process is convenient and manufacture difficulty and production cost are lowered on the condition that sealing effect is ensured.
Description
Technical field
The utility model relates to a kind of novel casting seal ring.
Background technique
Annular graded region in the existing particle classifying equipment and the sealing between the internal rotor graded region are mostly adopted upper and lower seal ring to form labyrinth seal and are realized.The upper and lower seal ring that diameter is larger adopts cast-in-block rich chromium cast iron blank to cast not only that difficulty is large but also yield rate is low, and the high hardness of upper and lower seal ring and casting defect cause larger difficulty to following process, not only expend many but also tool wear fracture in man-hour frequent, directly affected manufacturing efficiency and product cost.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome defects, processing is simple, convenient, the novel casting seal ring of good sealing effect.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of novel casting seal ring, it is characterized in that, and seal ring is comprised of a plurality of five equilibrium circular arcs, and the both sides of five equilibrium circular arc are respectively arranged with groove and the projection of mutual coupling.
The attachment portion of adjacent Equal round arc fluting and projection is filled with sealer.
Be provided with bolt hole on the described five equilibrium circular arc.Bolt hole can be connected with external equipment, makes things convenient for follow-up work.
Described groove and projection are the square shape structure of mutually mating.
Described groove and projection are the L shaped structure of mutually mating.
The five equilibrium circular arc can be judged its length scale and quantity according to actual casting condition and precision needs.
The beneficial effect that the utility model has is: seal ring is divided into a plurality of independent parts, by rational connecting method splicing, and by filling with sealant, guarantees under the prerequisite of sealing effect, convenient processing has reduced manufacture difficulty and cost of production.
Description of drawings
Fig. 1 is minute circular arc structural representations such as square shape;
Fig. 2 is L shaped five equilibrium circular arc structural representation;
Among the figure: 1, five equilibrium circular arc; 2, projection; 3, groove; 4, sealer; 5, bolt hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
Novel casting seal ring as shown in Figure 1, seal ring is comprised of a plurality of five equilibrium circular arcs 1, and the both sides of five equilibrium circular arc 1 are respectively arranged with groove 3 and the projection 2 of mutual coupling.Groove 3 and projection 2 are the square shape structure of mutually mating, and the groove 3 of adjacent five equilibrium circular arc 1 and the attachment portion of projection 2 are filled with sealer 4.Sealer 4 guarantees sealing effect.
Embodiment 2:
Novel casting seal ring as shown in Figure 2, its groove 3 and projection 2 are the L shaped structure of mutually mating, the other the same as in Example 1.
Claims (5)
