Abstract
The utility model relates to a spring ring type sealing filler, which can effectively solves the problem that when used, mechanical seal fillers need to be adjusted and replaced frequently because of wear. The utility model is a helical rubber ring with a rectangular cross section and can be combined and tightly pressed in a filler cavity, the spring ring type sealing filler and the filler cavity mutually generate and keep axial elastic force, and diameter of an inner hole of each spring ring is smaller than the diameter of a shaft matched with the spring ring, so that radial elastic force is generated. The inner surfaces of the inner holes are formed by the composition of high strength fibre and the rubber spring rings and are sprayed with wear resistant material. The utility model has the advantages of favorable sealing performance, long service life, and no need for frequent adjustment.
Description
The utility model relates to a kind of stuffing box packing, the stuffing box packing of especially a kind of spring ring formula.
Conventional sealing normally joins the bar shaped filler of some plasticity in the packing cavity, makes filler and the axle keep closely contacting and realizes sealing through axial compression.The filler that plastic deformation after this pressured the contracting seals need often be adjusted in the using process and could guarantee its sealability, uses the leakage that is caused just cannot not see brightly in detail because of frequent.
The purpose of this utility model is to provide the stuffing box packing of a kind of spring ring formula, and it can rely on lax that self elastic compensating wearing and tearing cause, and it has easy to use, good seal performance, the characteristics of long service life.
For achieving the above object, it is the helical opening rubber ring of rectangle that the utility model has adopted a kind of cross section, and with after its a plurality of combinations, be pressed in the packing cavity, what rely on is the elastic force that produces each other, promptly axial elastic force, and each spring ring diameter of bore all is slightly less than the diameter of the axle that matches, so they have a suitable radical elasticity with between centers again, thereby reach the optimal seal state.
After adopting said structure, suitable axially radical elasticity need not regular maintenance, makes it durable in use because of the peculiar elasticity of gum filler makes it to remain with axle, and sealability is better.
The utility model is described in further detail in conjunction with the accompanying drawings and embodiments more below.
Fig. 1 is (radially) of the present utility model plan view.
Fig. 2 is (axially) of the present utility model right elevation.
Among the figure: 1, wearing layer, 2, otch, 3, endoporus, 4, stuffing box packing.
In Fig. 1, (1) is the wearing layer of endoporus (3), and it is to be composited with high strength fibre and stuffing box packing (4) (that is spring ring), the mutual surface friction drag when surface spraying antifriction material is used for overcoming the filler distortion.Find out from its profile: it is that a cross section is the spiral helicine opening rubber ring of rectangle, and otch (2) locates to process axial 15 degree angle, the radially angles of 20 degree, otch (2) two ends are mutual superposition, during dismounting, open gland, spring ring can upspring and form one voluntarily and take out the angle.The stuffing box packing of this spring ring formula has good airproof performance, long service life, and convenient disassembly does not need the characteristics of often adjusting.
Claims (1)
- The stuffing box packing of a kind of spring ring formula, it is the helical rubber ring that a cross section is a rectangle, it is characterized in that: the surface recombination at endoporus (3) has one deck wearing layer (1), and two otch (2) are overlapping up and down; Its feature is that also otch (2) is located and axially forms 15 degree angles, radially forms 20 degree angles.
