Abstract
The utility model discloses an intake pipe seal gasket, including the metal substrate, the air vent has been seted up to the middle part of metal substrate, and the upper surface of metal substrate bonds and has upper portion rubber layer, and the lower surface of metal substrate bonds and has lower part rubber layer, and the outside edge of metal substrate bonds and has marginal rubber layer, and the sealed protruding muscle of round is respectively established to upper portion rubber layer, lower part rubber layer, marginal rubber layer structure as an organic whole on upper portion rubber layer and the lower part rubber layer. The utility model discloses can be used to sealed between the lid of intake pipe and engine cylinder, have sealing performance good, to operational environment strong adaptability's beneficial effect.
Description
Technical field
The utility model relates to engine fittings technical field, relates to a kind of suction tude gasket seal specifically.
Background technique
Suction tude gasket seal is the accessory sealed arranged between to prevent from, between suction tude and engine cylinder cap, gas leak phenomenon occurs.Existing suction tude gasket seal is generally adopt a circle pressure ripple above the sheet metal of coating rubber layer to seal.Pressure ripple mentioned here refers to and is located at one on suction tude pad to enclose the accordion-like of seal action protruding, can resilience after this accordion-like projection is extruded, and plays seal action.The shortcoming of this suction tude gasket seal is that pressure ripple rebound degree is low, and after long-time use, sealing effect is deteriorated, and easily leak air phenomenon.Along with the raising day by day required is leaked, in the urgent need to the better suction tude gasket seal of a kind of sealability to three in market.
Summary of the invention
The purpose of this utility model is to provide a kind of suction tude gasket seal of favorable sealing property.
For achieving the above object, the utility model comprises metal substrate, the intermediate portion of metal substrate offers vent, the upper surface of metal substrate is bonded with upper rubber layer, the lower surface bonds of metal substrate has lower rubber layer, the outer ledge place of metal substrate is bonded with boundary rubber layer, and upper rubber layer, lower rubber layer, boundary rubber layer are structure as a whole, and upper rubber layer and lower rubber layer respectively establish a circle seal bead.
Seal bead on described upper rubber layer and lower rubber layer is symmetrical arranged up and down, and the cross section of seal bead is the trapezium structure narrowed gradually to its top by base portion.
Described metal substrate is provided with two lugs, upper rubber layer, lower rubber layer, boundary rubber layer are equipped with the expansion corresponding with lug and by expansion, lug is completely coated, a positioning convex column is respectively established at position corresponding with two lugs on upper rubber layer.
The both sides that two lug offices on described metal substrate are relative on metallic substrates.
Described positioning convex column is cone structure.
Described upper rubber layer, lower rubber layer, boundary rubber layer are fluororubber layer.
The utility model take metal substrate as skeleton, and upper and lower surface and the outer ledge place of metal substrate are coated with rubber layer, and this structure can take into account consistency and elasticity two kinds of characteristics, suction tude and cylinder head can be made to fit tightly, play good seal action; Upper rubber layer, lower rubber layer, boundary rubber layer are structure as a whole, and this structure can make the bonding of rubber layer and metal substrate more firmly and rubber layer is more prone to when manufacturing shaping; Upper rubber layer and lower rubber layer respectively establish a circle seal bead, and this structure can promote backlash compensation ability and the rebound degree of pad further, and the utility model still can be kept and suction tude, the fitting tightly of cylinder head in vibration environment.Seal bead on upper rubber layer and lower rubber layer is symmetrical arranged up and down, the trapezium structure that the cross section of seal bead is narrowed to its top gradually by base portion, this structure can ensure that seal bead there will not be the problems such as dislocation, fold when compressive strain, guarantees good sealability; Metal substrate is provided with two lugs, and a positioning convex column is respectively established at position corresponding with two lugs on upper rubber layer, and positioning convex column can be embedded in the positioning hole be located in cylinder head, plays the effect locating and prevent the changing of the relative positions; The both sides that two lug offices on metal substrate are relative on metallic substrates, two positioning convex column scattering devices, this structure can ensure accurate positioning; Positioning convex column is cone structure, and it is more prone to being separated with the combination of positioning hole, is conducive to installation and removal of the present utility model; Upper rubber layer, lower rubber layer, boundary rubber layer are fluororubber layer, and it has the characteristic such as good high temperature resistant, oil resistant, chemically-resistant, resistance to combustion, and using effect is good, long service life.
In sum, the utility model can be used for the sealing between suction tude and engine cylinder cap, has good seal performance, the beneficial effect strong to working environment adaptability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described in detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is along the structural representation after the cutting of A-A direction in Fig. 1.
Embodiment
With reference to accompanying drawing, this suction tude gasket seal comprises metal substrate 1, the intermediate portion of metal substrate 1 offers vent 2, metal substrate 1 defines the skeleton of suction tude gasket seal, the upper surface of metal substrate 1 is bonded with upper rubber layer 3, the lower surface bonds of metal substrate 1 has lower rubber layer 4, the outer ledge place of metal substrate 1 is bonded with boundary rubber layer 5, upper rubber layer 3, lower rubber layer 4, boundary rubber layer 5 is structure as a whole, this structure can make the bonding of rubber layer and metal substrate 1 more firm, and rubber layer is more prone to when manufacturing shaping.Preferably, upper rubber layer 3, lower rubber layer 4, boundary rubber layer 5 are fluororubber layer, and it has the characteristic such as good high temperature resistant, oil resistant, chemically-resistant, resistance to combustion, can obtain better using effect and longer working life.Upper rubber layer 3 and lower rubber layer 4 respectively establish a circle seal bead 6, increase backlash compensation ability and the rebound degree that can promote suction tude gasket seal after seal bead 6 further, it still can be kept and suction tude, the fitting tightly of cylinder head in vibration environment.As further improvement, upper rubber layer 3 is symmetrical arranged with the seal bead about 6 on lower rubber layer 4, the cross section of seal bead 6 is the trapezium structure narrowed gradually to its top by base portion, this structure can ensure that seal bead 6 there will not be the problems such as dislocation, fold when compressive strain, guarantees good sealability.As further improvement, metal substrate 1 is provided with two lugs 7, upper rubber layer 3, lower rubber layer 4, boundary rubber layer 5 are equipped with the expansion corresponding with lug 7 and by expansion, lug 7 is completely coated, a positioning convex column 8 is respectively established at position corresponding with two lugs 7 on upper rubber layer 3, two lug 7 points on metal substrate 1 is in both sides relative on metal substrate 1 and corresponding with the positioning hole in cylinder head, and positioning convex column 8 is cone structure.Positioning convex column 8 can be embedded in the positioning hole be located in cylinder head, plays the effect locating and prevent the changing of the relative positions, and the positioning convex column 8 of cone structure is easy to combine with positioning hole and be separated more, is conducive to the installation and removal of suction tude gasket seal.
