Abstract
The utility model relates to a composite sealing gasket which is an ideal air-sealing device for the mechanical equipment, such as an air compressor, an oxygenerator, a vacuum pump, etc. The utility model has the technical proposal that an asbestos and a sikkim soft body are combined with an annular aluminum husk, a red copper husk or a stainless steel husk, and compared with the existing aluminum gasket or copper gasket, the composite sealing gasket has the advantages of attractive appearance, good tightness, long service life, low cost and corrosion resistance. The composite sealing gasket is an ideal sealing gasket for mechanical connection of the air compressor in industrial and mining enterprises.
Description
The utility model is about the improvement of seal washer invention, particularly air compressor, oxygenerator, the sealing gasket of mechanical connection position such as vacuum pump and air valve.
In the prior art, the air valve sealing pad of air compressor all is to adopt aluminium backing or copper backing usually, though this pad also can play the gas shutoff seal action, and high material consumption, working life is short, poor sealing performance.
In view of the problem that known technology exists, the purpose of this utility model is to design a kind of compound sealing gasket, and this sealing gasket cost is reduced, and quality improves, and is easy to use, the sealing gasket at the desirable mechanical connection position that the life-span prolongs.
The utility model is finished as follows, the material (2) that will have sealed nature is by the aluminum annular-shaped skin, and copper sheet or stainless steel sheet (1) are laminated with, and just become desirable sealing gasket, its circular crosssection can be circular with reference to accompanying drawing, also can be the flat with two cambered surfaces.The material of described sealed nature (2) can be asbestos or tin metal software.
The utility model is compared with known aluminium backing or copper backing, have that cheap, quality improves, easy to use, life-span prolongs, use at mechanical connection positions such as air compressors by the compound sealing gasket of the utility model design motif made to produce positive effect, after applying, can be country and save a large amount of non-ferrous metals.
The utility model has following accompanying drawing:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is that the utility model is along the A-A sectional view;
Fig. 3 is the flat packing sectional view that has two cambered surfaces;
Fig. 4 is circular air valve sealing pad sectional view;
Accompanying drawing has been represented entire infrastructure of the present utility model, the embodiment cross section is respectively circular and two kinds of flats, as long as asbestos or tin metal software (2) are placed on the sheet copper (1) that punching out forms, through the science extrusion modling, joining place after sheet copper (1) coats asbestos or tin metal software (2) is fitted like a glove get final product.
Claims (4)
1, a kind of compound sealing gasket has the aluminum annular-shaped skin, the material (2) of sheet copper or stainless steel sheet (1) and sealed nature, and the material (2) and aluminium skin that it is characterized in that having sealed nature, sheet copper or stainless steel sheet are compound.
2, compound sealing gasket as claimed in claim 1, the material (2) that it is characterized in that having sealed nature are by the aluminium skin, and the cross section that sheet copper or stainless steel sheet (1) are laminated with can be circular, also can be the flat with two cambered surfaces.
3, compound sealing gasket as claimed in claim 1, the material (2) that it is characterized in that having sealed nature is asbestos.
4, compound sealing gasket as claimed in claim 1, the material (2) that it is characterized in that having sealed nature is the tin metal software.
