Abstract
A composite sealing hard washer is characterized in that the utility model is a seven-layer composite structure comprising a rubber layer, a fibre rubber layer, a rubber layer, a skeleton ring, a rubber layer, a fibre rubber layer, a rubber layer in turn. The utility model solves the technical problem of improving the composite mechanical property of the plane gasket so as to reduce manufacturing costs, save cooper materials and be convenient for installation.
Description
Technical field:
The utility model is the compound hard packing circle of using about mechanical seal.
Background technique:
Sealing is the most frequently used part of machine static seal leakage proof with the hard packing circle.Present sealing hard packing circle can be divided into following two classes haply:
The first kind is the sealing hard packing circle that commaterial is made, and material commonly used has non-ferrous metals such as red copper, aluminium.The advantage of this type of packing ring is simple in structure, easily manufactured, and shortcoming is that performance is decided by fully that employed material, resilience are poor, lost efficacy easily and seepage can not be reused, and will consume a large amount of non-ferrous metals, and cost is higher.
Second class is rubber combined hard packing circle, make on the metal frame circle by the vulcanization of rubber, its pressure-resistant seal performance is subjected to the rubber manufacturing machinery performance limitations, and owing to technologic reason and device-restrictive to be not easy to produce internal diameter bigger, and less in batches sealing hard packing circle, thereby the cost of single-piece or small lot batch manufacture is improved.
More than the common drawback of two class packing rings are restrictions that its comprehensive mechanical performance is subjected to material, and manufacture cost height.
Summary of the invention:
The purpose of this utility model is to provide a kind of sealing hard packing circle, solves to improve sealing hard packing circle comprehensive mechanical performance, reduces manufacture cost, the convenient technical problem of installing, saving non-ferrous metal.
The technological scheme that the utility model addresses the above problem is as follows:
A kind of compound hard packing circle is characterized in that this compound hard packing circle is made of seven layers of composite structure of one successively rubber layer, fiber rubber layer, rubber layer, the skeleton ring that has convex shoulder, rubber layer, fiber rubber layer, rubber layer.
This rubber layer is natural rubber and all kinds of synthetic rubber.
This fiber rubber layer is the mixture of rubber and fabric.Rubber is infiltrated fabric and is inserted pore and the microgap that is formed by the graticule that interweaves by the fabric two sides.
This skeleton ring is made by steel or other metallic material, has convex shoulder.When off working state, the skeleton ring convex shoulder is lower than the height of rubber and fiber rubber layer; Keep little gap between the outer garden cylinder of the interior garden cylinder of skeleton ring convex shoulder and rubber layer fiber rubber layer; The internal diameter of rubber layer and fiber rubber layer has promptly increased by a loop material in the compression face inboard of rubber layer and fiber rubber layer less than the skeleton ring internal diameter.When skeleton ring is formed from steel, copper coating or zinc-plated.
The utility model has made full use of the advantage performance of layers of material, has remedied deficiency separately, and structurally also rubber layer and fiber rubber layer has been taked enhancement measures.Therefore improved its comprehensive mechanical performance, it has following advantage:
1, rubber material and fabric web material can be selected, to satisfy the actual demand that uses.
2, guarantee enough elastic compression amount and rebound degree, have good sealing reliability and sufficiently long working life.
3, can be repeatedly used, reduce maintenance expenses, convenient for maintaining.
4, save non-ferrous metal.
5, can utilize current production devices, technology and raw material, not only can be mass-produced but also can reduce small lot batch manufacture or piece-production cost.
6, with existing all kinds of sealing hard packing circles good interchangeability is arranged.
7, easy for installation.
Description of drawings:
Fig. 1 is a sectional drawing of the present utility model, and Fig. 2 is its projection drawing.
The 1-rubber layer; 2-fiber rubber layer; The 3-rubber layer; The 4-skeleton ring; The 5-rubber layer; 6-fiber rubber layer; The 7-rubber layer.
Embodiment:
See also shown in Figure 1.The seven layer composite structure of the utility model for constituting by rubber layer 1, fiber rubber layer 2, rubber layer 3, skeleton ring 4, rubber layer 5, fiber rubber layer 6, rubber layer 7 successively, wherein:
This rubber layer 1, rubber layer 3, rubber layer 5, rubber layer 7 are natural rubber and all kinds of synthetic rubber, for example: styrene butadiene rubber, butyl rubber, nitrile butadiene rubber, neoprene, fluorine rubber, silicone rubber, different rubber, Thiokol, polyurethane rubber, the butadiene rubber etc. defended are combined on fiber rubber layer 2, the fiber rubber layer 6 through sulfuration, and wherein rubber layer 3 and rubber layer 5 also are combined on the skeleton ring 4 through sulfuration.Mainly be utilize that it is water-fast, oil resistant, heat resistance and elasticity.Can be according to the satisfactory rubber of actual conditions optimized choice performance of sealing.
This fiber rubber layer 2 and fiber rubber layer 6 are mixtures of fabric and rubber, rubber infiltrates towards fabric is inner from two of fabric, insert the tiny cavity or the trickle slit that form between the graticule that fabric interweaves, above-mentioned fabric is mainly by chemical fibre or chemical fibre and natural fibre blended fabrics such as cotton, fiber crops.This fiber rubber layer 2 and fiber rubber layer 6 can make compressive strength, rigidity, pressure elasticity deformation rate and the response rate of combination rubber layer thereon improve.Can be according to the satisfactory fabric of actual conditions optimized choice performance of sealing.
This skeleton ring 4 is made by metallic material (steel etc.) or the good material of other intensity.
This skeleton ring is shaped on convex shoulder, and when the non-stress state, this convex shoulder is lower than rubber layer 1 and rubber layer 7, when compound hard packing circle pressurized, plays pressure-bearing and position-limiting action, prevents that rubber layer and fiber rubber layer from being damaged by excess compression or shorten the life-span.Simultaneously, loosening effect is tightened and prevented to the guaranteed associated fitting of this convex shoulder (as the pipe connecting bolt).Keep little gap between the outer garden cylinder of the interior garden cylinder of this convex shoulder and rubber layer fiber rubber layer,, thereby improved their elastic resistance the big restricted effect of rising of rubber layer, the external diameter of fiber rubber layer when bearing pressure.
Its copper coating or zinc-plated when skeleton ring 4 is formed from steel can improve the bonding strength between rubber layer 3, rubber layer 5 and the skeleton ring.And it is corrosion-resistant, attractive in appearance.In order to improve before the bonding strength sulfuration pre-painted adhesive on the binding face of skeleton ring.
The diameter of rubber layer and fiber rubber layer endoporus has promptly increased by a loop material in the inboard of rubber layer and fiber rubber layer compression face less than the skeleton ring internal diameter, and part in compression is had humidification.Simultaneously associated fitting (as pipe connecting bolt etc.) there are " holding tightly " effect and centering effect, correct position when making assembling, and the hard packing circle can not take place come off, made things convenient for assembling work.The edge of this endoporus can also omit undulate on demand.
As mentioned above, the utility model constituted one have high strength, high rebound degree, sealing reliability good, easy to assembly, can durablely use, attractive in appearance, corrosion resistant excellent sealing hard packing circle.The compressibility of its rubber layer and fiber rubber layer is about 25%, and rebound degree reaches about 95%, and sealing load can reach more than the 2.5MPa.
