Description
Technical Field
The utility model belongs to the technical field of seal structure, concretely relates to be applied to accord with seal structure of rolling mill.
Background
In the metallurgical industry, when a rolling mill works, cooling water is poured on the surface of a hot steel ingot, and water vapor carries iron oxide skin scraps to splash everywhere. On the surface of a friction pair with relative motion, high-hardness iron oxide scale chips cause damage of a sealing original piece and lose the sealing effect, sealing failure is finally caused, and water and the iron oxide scale chips enter the friction pair to cause corrosion and abrasion of parts and influence on normal operation of a unit.
The packing sealing has larger sealing contact surface, so the packing sealing is more applied to occasions with high dust content, but the sealing effect is influenced by the influence of the self performance of the packing sealing material and the clearance of the sealing surface after the packing sealing is used for a period of time. Due to the existence of the chamfer, when parts move relatively, high-hardness iron scale chips are easily brought into a sealing surface, so that the rubber sealing element is damaged, and sealing failure is caused.
Disclosure of Invention
The utility model discloses just to above-mentioned problem, a be applied to high dust content occasion rolling mill operation is provided, long service life, sealed reliable composite seal structure.
In order to realize the above object of the utility model, the utility model discloses a following technical scheme, the utility model discloses a rubber strip, its characterized in that: an outer layer filler is arranged outside the rubber strip.
As an optimized scheme of the utility model, the rubber adhesive tape cross-section sets up to X shape structure, and four angles of X shape are the same with four angle directions of packing.
Furthermore, four endpoints of the X-shaped cross section of the rubber strip are circular, and the diameter of the circular part is larger than the connecting part of the circular part and the center of the rubber strip.
Furthermore, the section of the outer layer filler is square.
The utility model has the advantages that: 1. the utility model discloses simple structure, after the sealed compression, the height of seal section reduces, and rubber adhesive tape produces elastic deformation, is equivalent to rubber adhesive tape and has the internal force of a support to outer packing for outer packing also keeps in close contact with because the effect of its inside supporting force guarantees outer packing and the sealed face of part even there is wearing and tearing, can guarantee lasting sealing effectively.
2. The utility model discloses a rubber adhesive tape can make in advance, and the circular part in the rubber adhesive tape four corners of X shape forms circular-arc pit with the coupling part at rubber adhesive tape center, guarantees that the combination of packing sealed and rubber adhesive tape can form reliable and lasting zonulae occludens.
3. The utility model discloses compound seal receives the normal pressure, and the cross-section is out of shape because of the pressurized production. The rubber adhesive tape of X shape has two kinds of deformation, one kind is that four limits of X shape use the center to produce angular deformation as the centre of a circle, and the other kind is that four circular portions of the rubber adhesive tape of X shape become the ellipse after the pressurized, and two kinds of deformations can take place simultaneously also can produce alone, and mutual noninterference and total deformation are great, and the power that these two kinds of deformations provided can effectively guarantee sealing performance.
4. The utility model discloses four angles of rubber strip of X shape are corresponding with four bights of the outer filler of square cross-section, no matter which two faces are pressed can both guarantee the same sealing performance, and the installation direction need not be considered when the installation of composite seal promptly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a usage state diagram of the present invention.
Fig. 3 is a partially enlarged view of fig. 2.
In the attached drawing, 1 is outer layer filler, 2 is a circular part, 3 is a connecting part, 4 is a rubber adhesive tape, and 5 is a pull rod.
Detailed Description
The utility model discloses a rubber strip 4, its characterized in that: an outer layer filler 1 is arranged outside the rubber strip 4.
As an optimized scheme of the utility model, 4 cross-sections of rubber strip set up to X shape structure, and four angles of X shape are the same with four angle directions of packing.
Further, four end points of the X-shaped cross section of the rubber strip 4 are set to be circular, and the diameter of the circular part 2 is larger than that of the connecting part 3 between the circular part 2 and the center of the rubber strip 4.
Further, the section of the outer layer filler 1 is square.
The utility model discloses during the use, will the utility model discloses the cover realizes that the pull rod 5 is outer to form sealedly outside the pull rod 5 of rolling mill.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
