Abstract
The invention provides a novel shaft seal device. The novel shaft seal device is simple in structure and good in sealing performance. The novel shaft seal device mainly comprises four 1/4 wedged rings (1), a wedged axial ring (2), a rubber ring (3), a shaft ring (4) and a deformable rubber sealing ring (5). The four 1/4 wedged rings (1) are embedded in the rubber ring (3) in the radial direction. According to the work principle, the outer diameter of the shaft seal device is adjusted by pushing the four 1/4 wedge rings (1) to move in the radial direction through the wedged axial ring (2), so that the fit gap of a shaft seal and a hole diameter is filled, and a good sealing effect is achieved. The shaft seal device has the advantages of being simple in structure, low in manufacturing cost, good in sealing performance, wide in application range, easy to install and the like.
Description
Technical field
The present invention relates to mechanical seal, provide a kind of Novel shaft seal apparatus, the use of this gland seal device, make in mechanical connection, to have better sealing.
Background technique
Shaft seal is a kind of friction sealed or stuffing box, and in order to prevent compressor or the leak of liquid between other conveying equipment for fluid substances axle and bearing, shaft seal is the seal arrangement preventing pump shaft and housing place from leaking and arranging.Conventional type of shaft sealing has packing seal, mechanical seal and power envelope.Packing seal structure is simple, low price, easy to maintenance.But leakage rate is large, power consumption penalty is large; The good sealing effect of mechanical seal, leakage rate is very little, and the life-span is long, but price, processing installation and maintenance maintenance is higher than general seal request.Dynamic seal reliable performance, low price, easy to maintenance, but power loss is large compared with mechanical seal, and the life-span of its parking sealing arrangement is shorter.In sum, above shaft seal respectively has pluses and minuses, and has certain narrow limitation in actual applications, the invention provides a kind of Novel shaft seal apparatus, the gland seal device of this design method has structure simply, and cost is low, good airproof performance, applied widely, and the advantages such as easy installation.
Summary of the invention
The object of this invention is to provide a kind of Novel shaft seal apparatus, this gland seal device structure is simple, easily installs, and has fabulous sealing.
The present invention is a kind of Novel shaft seal apparatus, and its working principle is the external diameter moving radially regulating shaft sealer by four 1/4 wedge annulus (1), thus fills up the matching gap of shaft seal and bore dia, reaches good sealing effect.
The present invention is primarily of four 1/4 wedge annulus (1), the axial annulus (2) of wedge, rubber ring (3), the axle collar (4) and deformable rubber seal ring (5) five part composition, wherein four 1/4 wedge annulus (1) radial directions are embedded on rubber ring (3), when axial annulus (2) axial motion of promotion wedge, four 1/4 wedge annulus (1) are moved radially, under the effect of 1/4 wedge annulus (1), the radius of rubber ring (3) becomes large, the outer ring of rubber ring (3) is made to be pressed on axis hole, thus fill up the matching gap of shaft seal and bore dia, 1/4 wedge annulus (1) and the axial annulus (2) of wedge are metalworks, non-deformable, when 1/4 wedge annulus (1) and the axial annulus (2) of wedge coordinate, the axial annulus (2) of wedge can axial advance, and after gland seal device completes installation on a mating the axial thrust load of pressure be less than the axial thrust load of frictional force on fitting surface, deformable rubber seal ring (5) internal diameter is connected on the axle collar (4), and external diameter is connected on rubber ring (3), ensures the sealing between the axle collar (4) and rubber ring (3).
Beneficial effect of the present invention is as follows: this Novel shaft seal apparatus structure is simple, and sealing is fabulous, and easily installs.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
In figure: 1.1/4 wedge annulus, 2. wedge axial annulus, 3. rubber ring, the 4. axle collar, 5. deformable rubber seal ring.
Embodiment
A kind of structure of Novel shaft seal apparatus as shown in Figure 1, by by four 1/4 wedge annulus (1), the axial annulus (2) of wedge, rubber ring (3), the axle collar (4) and deformable rubber seal ring (5) five part composition.
As shown in Figure 1, four 1/4 wedge annulus (1) radial directions are embedded on rubber ring (3), 1/4 wedge annulus (1) and axial annulus (2) cone match of wedge, deformable rubber seal ring (5) internal diameter is connected on the axle collar (4), external diameter is connected on rubber ring (3), ensures the sealing between the axle collar (4) and rubber ring (3).
When axial annulus (2) axial motion of promotion wedge, four 1/4 wedge annulus (1) are moved radially, under the effect of 1/4 wedge annulus (1), the radius of rubber ring (3) becomes large, the outer ring of rubber ring (3) is pressed on axis hole, thus fills up the matching gap of shaft seal and bore dia; 1/4 wedge annulus (1) and the axial annulus (2) of wedge are metalworks, non-deformable, when 1/4 wedge annulus (1) and the axial annulus (2) of wedge coordinate, the axial annulus (2) of wedge can axial advance, and after gland seal device completes installation on a mating the axial thrust load of pressure be less than the axial thrust load of frictional force on fitting surface.
Shown in Fig. 1, be primarily characterized in that: by the external diameter moving radially regulating shaft sealer of four 1/4 wedge annulus (1), thus fill up the matching gap of shaft seal and bore dia, reach good sealing effect.
