The model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sealing gasket for the supercharged engine vent systems, it is by utilizing elastic plate to provide active force outwardly for pressing block, and utilize the end face of pressing block to be sealed, can increase area, the raising sealing effect of sealing area.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is as follows:
A kind of sealing gasket for the supercharged engine vent systems, comprise pressing block in the form of a ring, along pressing block, circumferentially be embedded in the elastic plate in pressing block; This pressing block has along the degrees of freedom of its thickness direction telescopic shape change.
Described pressing block is the mica paper briquetting.
The extension track of described elastic plate is one around the outside from coil to coil of the axis of pressing block, to curl up the plane curve of formation.
The cross section undulate of described elastic plate.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by adopting the combination design of pressing block and elastic plate, in pressurized process, the end face of pressing block is sealed with flanged surface under the reaction force of elastic plate, therefore, with the sealing gasket that existing employing potted line is sealed, compare, the utility model is sealed by the end face that utilizes pressing block, can increase the area of sealing area, improves its sealing effect; Described pressing block is set to the mica paper briquetting, in the dynamic operation of motor, by utilizing the compression resilience of mica paper briquetting, can make up the processing roughness of flanged surface, plays the effect of micro-sealing, further to improve sealing effect.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understand the utility model technical thought required for protection so that clearer.
As shown in Figure 5,6, be a kind of sealing gasket for the supercharged engine vent systems of model utility, comprise pressing block 2 in the form of a ring, along pressing block 2, circumferentially be embedded in the elastic plate 1 in pressing block 2; This pressing block 2 has along the degrees of freedom of its thickness direction telescopic shape change.Wherein, the S in Fig. 5 is to being the circumferential of pressing block 2.In actual design, this elastic plate 1 can circumferentially being embedded in pressing block 2 with paths such as circle, snail lines along pressing block 2.The utility model can improve the stability of pressing block 2 structures by the supporting effect that utilizes elastic plate 1, and can be pressing block 2 active force outwardly is provided; And because pressing block 2 has along the degrees of freedom of its thickness direction telescopic shape change, therefore, can under extraneous pressure-acting, be compressed, be beneficial to the formation of sealing, and can stretch next time at the reaction force of elastic plate 1, be beneficial to maintain sealing in the situation that flange distortion is larger.
In use, gas is along A to flowing, sealing gasket is pressed between the flange of the flange of gas exhaust manifold and pressurized machine, now, this elastic plate 1 pressurized produces reaction force, and this reaction force is put on to pressing block 2, the end face of pressing block 2 under the reaction force of elastic plate 1 with the flanged surface close contact, thereby avoid gas to let out between two relative flanged surfaces.The utility model is by adopting the combination design of elastic plate 1 and pressing block 2, in pressurized process, the end face of pressing block 2 is sealed with flanged surface under the reaction force of elastic plate 1, the end face of this pressing block 2 is formed at the sealing area of sealing pad, therefore, at sealing gasket under measure-alike prerequisite, the utility model is compared with the sealing gasket that existing employing three seals line is sealed, it is sealed by the end face that utilizes pressing block 2, can increase the area of sealing area, improve its sealing effect.
Described elastic plate 1 adopts the spring steel that nickel content is 11%-18% to make.The utility model, by the material of elastic plate 1 rationally is set, can improve the resistance to high temperature of elastic plate 1.Preferably, elastic plate 1 adopts the spring steel that nickel content is 15% to make, and to meet resistance to high temperature simultaneously, also can effectively control its cost.The cross section undulate of described elastic plate 1, to improve its compression and resilience.As shown in Figure 7, the extension track of described elastic plate 1 is one around the outside from coil to coil of the axis of pressing block 2, to curl up the plane curve of formation.By adopting said structure, can increase the number of turns of elastic plate 1 in pressing block 2, make pressing block 2 stressed more even everywhere, further to improve its sealing effect.Wherein, the number of turns that elastic plate 1 curls up can be set according to actual demand.
Certainly; the extension track of described elastic plate 1 can also be set to toroidal etc.; but the extension track of elastic plate 1 is set to one curls up the plane curve of formation around the outside from coil to coil of the axis of pressing block 2, is optimal case of the present utility model, and it can significantly improve sealing effect.
Described pressing block 2 is the mica paper briquetting, in the dynamic operation of motor, by utilizing the compression resilience of mica paper briquetting, can make up the processing roughness of flanged surface, plays the effect of micro-sealing, further to improve sealing effect.
Wherein, the heat resisting temperature of this elastic plate 1 and pressing block 2 can be set according to actual conditions, and it is preferred, the heat resisting temperature of this elastic plate 1 and pressing block 2 is 800 ° of C-1100 ° of C, but make the requirement that this elastic plate 1 and pressing block 2 satisfied temperatures are the following operating mode of 800 ° of C-1100 ° of C, thereby enlarge its Applicable scope.
Certainly, described sealing gasket, except can be used for sealing between gas exhaust manifold and pressurized machine, also can be diverted to other field, and for sealing other component.
The processing method of the above-mentioned sealing gasket for the supercharged engine vent systems, comprise the following steps;
Step 1: as shown in Figure 8,9, paper shape wrap member 21 is wrapped in to the outside of elastic plate 1, forms material strip;
Preferably, described paper shape wrap member 21 is mica paper, to be convenient to processing, and can play micro-seal action.
Step 2: then by this material strip circle around being coiled strip;
In step 2, the material strip circle around the number of turns can set according to the length of elastic plate 1, for example, can enclose around a circle, two the circle or two the circle more than.And for improve its circle around efficiency, can also be by instruments such as rolls.
Step 3: finally utilize mould by the coiled strip compacting in the form of a ring, now, the paper shape wrap member 21 of each layer forms the pressing block 2 of ring-type through pressing, and elastic plate 1 circumferentially is embedded in pressing block 2 along pressing block 2.
Concrete, in course of working, first coiled strip is placed in the ring die cavity of mould, then drive that the top die of mould is descending applies downward pressure to coiled strip, thereby coiled strip is compressed to one, and moulding is in the form of a ring.Preferably, elastic plate 1 adopts the spring steel that nickel content is 11%-18% to make, and, in step 3, this elastic plate 1 is pressed undulate under the pressure-acting of top die, to improve its compression resilience.
