Abstract
A kind of seam formula graphite grazing loop device, its structure is made up of spring, fluting flush end holding screw, graphite flake, it is characterized in that graphite-seal ring is spliced by three lobe graphite flakes and is formed by spring banding; Graphite flake two ends are with seam, and the not ipsilateral of seam deflection graphite flake, seam is all arranged along non-radial direction, and the medial surface matched fits tightly, leave compensate for clearance between end face; Fluting flush end holding screw inserts in groove and prevents graphite-seal ring from moving in a circle.This device has that structure is simple, use safety, good airproof performance, compensation rate large, splicing firmly, the feature of long service life.
Description
Technical field
The utility model relates to a kind of seal ring apparatus, especially a kind of graphite grazing loop device.
Background technology
In industrial processes, the blower fan of the special gas such as conveying coal gas is widely used in each industrial department, and gas medium leaks and not only can reduce fan efficiency, also seriously may jeopardize personal safety, therefore blower fan axle head sealing problem, causes concern and the attention of people gradually.Carry the blower fan axle head of the special gas such as coal gas to adopt graphite grazing under normal circumstances, graphite-seal ring is the important component part of graphite grazing.Graphite-seal ring splicing of the prior art has gap, and compensation rate is little, and axile displacement situation easily occurs in use procedure, and service life is short.
Utility model content
The utility model is intended to overcome above-mentioned defect, and object is to provide that a kind of use safety, good airproof performance, compensation rate are large, a kind of seam formula graphite grazing loop device of long service life.
For achieving the above object, the technical solution adopted in the utility model is: its structure is made up of spring, fluting flush end holding screw, graphite flake, it is characterized in that graphite-seal ring is spliced by three lobe graphite flakes and is formed by spring banding; Graphite flake two ends are with seam, and the not ipsilateral of seam deflection graphite flake, seam is all arranged along non-radial direction, and the medial surface matched fits tightly, leave compensate for clearance between end face; Fluting flush end holding screw inserts in groove and prevents graphite-seal ring from moving in a circle.
Accompanying drawing explanation
Fig. 1 is a kind of seam formula of the utility model graphite-seal ring apparatus structure schematic diagram;
Fig. 2 is the side schematic view of a kind of seam formula of the utility model graphite grazing loop device;
Fig. 3 is the graphite flake schematic diagram of a kind of seam formula of the utility model graphite grazing loop device;
In the drawings: 1, spring; 2, fluting flush end holding screw; 3, groove; 4, graphite flake; 4a, seam; 4b, seam.
Detailed description of the invention
Below in conjunction with accompanying drawing, explanation is described further to the utility model.
A kind of seam formula graphite grazing loop device, its structure is made up of spring (1), fluting flush end holding screw (2), graphite flake (4), it is characterized in that graphite-seal ring is spliced by three lobe graphite flakes (4) and is formed by spring (1) banding; Graphite flake (4) two ends are with seam (4a) and seam (4b), and seam (4a) and seam (4b) are partial to the not ipsilateral of graphite flake (4), seam (4a) and seam (4b) are all arranged along non-radial direction, and the medial surface matched fits tightly, leave compensate for clearance between end face; Fluting flush end holding screw (2) inserts in groove (3) and prevents graphite-seal ring from moving in a circle.Graphite annulus splicing gapless can be ensured by seam splicing, prevent from, between graphite ring plate, axile displacement occurs.Graphite flake (4) two ends are with seam, and the not ipsilateral of deflection graphite flake (4).Seam is arranged along non-radial direction, increases the contact area in seam face, improves sealing property.Leave gap between two seams matched, when graphite flake (4) inner headed face is worn and torn under the effect of spring (1) part of compensate for wear, its compensation rate is large, extends service life.
Therefore, this device have that structure is simple, use safety, good airproof performance, compensation rate large, splicing firmly, the feature of long service life.
Claims (1)
1. a seam formula graphite grazing loop device, its structure is made up of spring (1), fluting flush end holding screw (2), graphite flake (4), it is characterized in that graphite-seal ring is spliced by three lobe graphite flakes (4) and is formed by spring (1) banding; Graphite flake (4) two ends are with seam (4a) and seam (4b), and seam (4a) and seam (4b) are partial to the not ipsilateral of graphite flake (4), seam (4a) and seam (4b) are all arranged along non-radial direction, and the medial surface matched fits tightly, leave compensate for clearance between end face; Fluting flush end holding screw (2) inserts in groove (3) and prevents graphite-seal ring from moving in a circle.
