Abstract
The invention discloses a gasket structure with a steel ring. The gasket structure includes a ring-shaped aluminum gasket body with a central hole, and a steel washer, wherein the steel washer is located on the inner ring side of the ring-shaped aluminum gasket body, and is closely adhered to the inner ring of the ring-shaped aluminum gasket. The structure is simple, the production technology is not complicated, and the gasket structure can solve the problem that a pure aluminum gasket is squeezed out during low-and medium-pressure high-temperature bolted flange connection; moreover, the gasket structure with the steel ring can bear part of a pretension force, so that when the aluminum gasket is relaxed due to a temperature rise or fluctuations, the steel ring can release elastic energy, and the influence on the sealing pressure of the aluminum gasket can be further reduced.
Description
Technical field
The present invention relates to gasket seal field, particularly relate to a kind of gasket construction with steel ring.
Background technique
In, in low-voltage high-temperature Bolted Flanged Connection process, prior art is all adopt fine aluminium flat gasket, because fine aluminium pad hardness is inadequate, is easy to be extruded, and comparatively large on the impact of aluminium circle seal pressure, then in needing a kind of novel pad of design to adapt to, low-voltage high-temperature Bolted Flanged Connection.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of gasket construction with steel ring, can solve the problems of the technologies described above completely.
The technological scheme solved the problems of the technologies described above is as follows:
With a gasket construction for steel ring, comprise the aluminum annular-shaped shim body with mesopore, also comprise a circle Steel Washer, described Steel Washer is positioned at the inner ring side of aluminum annular-shaped shim body, is close to the inner ring of aluminum annular-shaped pad.
The thickness of described Steel Washer generally selects 1 ~ 3mm.The thickness of Steel Washer is subject to the impact of aluminum annular-shaped shim body size, the Steel Washer of external diameter between 1 ~ 10mm for aluminum annular-shaped pad adopts the thickness of 1mm, the Steel Washer of external diameter between 10 ~ 20mm for aluminum annular-shaped pad adopts the thickness of 2mm, and the Steel Washer of external diameter between 20 ~ 30mm for aluminum annular-shaped pad adopts the thickness of 3mm.
Structure of the present invention is simple, production technology is uncomplicated, and can overcome fine aluminium pad in, the problem that is extruded in low-voltage high-temperature Bolted Flanged Connection, and the gasket construction of band steel ring can bear a part of pretightening force, when raising when temperature or cause aluminium backing to loosen because of fluctuation, steel ring discharges elasticity energy, so also decreases the impact on aluminium circle seal pressure simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is using state figure of the present invention;
In figure, 1 is aluminum annular-shaped shim body, and 2 is Steel Washer, and 3 is flange.
Embodiment
A kind of gasket construction with steel ring as shown in Figure 1, comprises the aluminum annular-shaped shim body 1 with mesopore, also comprises a circle Steel Washer 2, and described Steel Washer 2 is positioned at the inner ring side of aluminum annular-shaped shim body 1, is close to the inner ring of aluminum annular-shaped shim body 1.The thickness of described Steel Washer 2 is 1 ~ 3mm.
When using of the present invention, flange design should be become the form of band twice seam, as shown in Figure 2.
Structure of the present invention is simple, production technology is uncomplicated, and can overcome fine aluminium pad in, the problem that is extruded in low-voltage high-temperature Bolted Flanged Connection, and the gasket construction of band steel ring can bear a part of pretightening force, when raising when temperature or cause aluminium backing to loosen because of fluctuation, steel ring discharges elasticity energy, so also decreases the impact on aluminium circle seal pressure simultaneously.
