Abstract
The utility model discloses an engine supercharger gasket. The gasket is rectangular, and the middle of the rectangular gasket is of an 8-shaped hollow structure. The gasket comprises a buckle loop, a hemming and a panel, and a space enclosed by the three parts is internally filled with a mica composite material; the buckle loop is arranged along the inner edge of the 8-shaped hollow structure; and the hemming is arranged at the rectangular side of the gasket. The hemming extends along the bottom of a mica filling layer and is overlap-jointed with one side of the panel mutually; and the buckle loop is overlap-jointed with the panel and the hemming respectively. The adoption of a composite structure, especially the use of the mica filler layer, leads the high-temperature resistance of the gasket to be stable and the tightness thereof to be better.
Description
Technical field
The utility model relates to a kind of engine supercharger, particularly a kind of mica pressurized machine pad.
Background technique
The engine supercharger pad is installed between exhaust outlet flange and the pressurized machine volute exhaust gas inlet flange, and the high-temperature gas that comes out to enter the pressurized machine volute from outlet pipe is played seal action.So the pressurized machine pad needs can be high temperature resistant, corrosion-resistant, and have certain elasticity, the nao-and micro relief that the energy compensating sealing surface occurs, good airproof performance.
Existing pressurized machine pad mainly contains 3 kinds: monolayer metal gasket, multilayer metal gasket and expanded graphite Composition spacer.Monolayer metal gasket generally adopts the thin corrosion resistant plate (1Cr18Ni9 or 1Cr17Ni7 or 0Cr18Ni9) of band convex tendon to be stamped to form.Multilayer metal gasket is general to be adopted two-layer or three layers of thin corrosion resistant plate riveted joint, and design has the convex tendon compensation sealing.Expanded graphite Composition spacer structure is: outer there is skeleton steel plate the centre in order to approach corrosion resistant plate, fills a certain amount of expanded graphite between thin corrosion resistant plate and the skeleton steel plate.
The major defect of pressurized machine pad prior art is that heat resistance is good inadequately, and sealability is stable inadequately with increasing service time.The expanded graphite combined supercharging device pad of prior art can only use under 700 ℃ high temperature for a long time at present, easily ablates when serviceability temperature surpasses 760 ℃.And single or multiple lift metal pressurized machine pad is along with the growth of service time, and its elasticity can constantly descend, and the sealing compensation ability drop causes poorly sealed and leaks gas.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, and by the employing composite structure, the use of particularly mica filled layer makes that the resistance to high temperature of pad is stable, better tightness.
Engine supercharger pad of the present utility model, pad is rectangular, and the rectangular washer middle part is 8 font hollow structures; Pad comprises buckles circle, bound edge and panel, and the three surrounds and fills mica composite material in the space that forms; The button circle is provided with along 8 font hollow structure inner edges; Bound edge is positioned on the rectangle side of pad.
Preferably, bound edge extends along mica filled layer bottom, and overlaps mutually in panel one side and panel; The button circle overlaps with described panel and bound edge respectively.
Preferably, mica composite material packed layer thickness is 1.4mm to 1.6mm; Button circle, bound edge and panel are corrosion resistant plate, and thickness is 0.15mm to 0.25mm; Button circle, bound edge, panel and packed layer material adopt the die stamping moulding, and fit tightly.
Compared with prior art, the utlity model has following beneficial effect:
1, the mica composite material (silicate) of packed layer employing, resistance to high temperature is better;
2, the composite structure of the corrosion resistant plate of pad internal and external layer and packed layer, but the nao-and micro relief that compensating sealing surface occurs, good airproof performance.
Description of drawings
Fig. 1 is the utility model engine supercharger pad front view;
Fig. 2 be among Fig. 1 A-A to sectional view.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1-detains circle, 2-bound edge, 3-mica composite material packed layer, 4-panel.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1 and Figure 2, engine supercharger pad of the present utility model is rectangular, and the rectangular washer middle part is 8 font hollow structures; Pad comprises buckles circle 1, bound edge 2 and panel 4, and the three surrounds and fills mica composite material (being mica composite material packed layer 3) in the space that forms; Button circle 1 is provided with along 8 font hollow structure inner edges; Bound edge 2 is positioned on the rectangle side of pad.Bound edge extends along mica composite material packed layer 3 bottoms, and overlaps mutually in panel one side and panel; Button circle 1 overlaps with panel 4 and bound edge 2 respectively.Mica composite material packed layer thickness is 1.4mm to 1.6mm.Button circle, bound edge and panel are corrosion resistant plate (1Cr18Ni9 or 1Cr17Ni7 or 0Cr18Ni9), and thickness is 0.15mm to 0.25mm.Button circle, bound edge, panel and packed layer material adopt the die stamping moulding, and fit tightly.
The mica composite material (silicate) that packed layer adopts, its composition is other prescriptions such as potassium oxide 6.8-10%, magnesium oxide 21.5-29%, aluminium sesquioxide 10.6-17%, silica 38.9-44%.Resistance to high temperature better (can anti-800 degrees centigrade high temperature); The corrosion resistant plate of pad internal and external layer and the composite structure of packed layer make its compressibility more than or equal to 10%, and rebound degree is more than or equal to 30%, but the nao-and micro relief that compensating sealing surface occurs, good airproof performance.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
