Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use typically refers to as " upper and lower, " with reference to shown in the drawings upper and lower; It is inside and outside that " inside and outside " refers to relative to the profile of each parts own.
The utility model provides a kind of combined type gasket construction, as depicted in figs. 1 and 2, comprise the first stacked up and down pad 1 and the second pad 2, this first pad 1 and the second pad 2 are formed with corresponding through hole 4 respectively, wherein, described combined type gasket construction also comprises mid seal 3, this mid seal 3 is between described first pad 1 and the second pad 2 and arrange around described through hole 4, and described mid seal 3 can form linear sealing respectively with described first pad 1 and the second pad 2.
First it should be noted that, in mechanical seal field, the sealing that the sealing of linear sealing seals usually above face.In combined type gasket construction of the present utility model, the mid seal 3 of linear sealing can be formed respectively with the first pad 1 and the second pad 2 owing to being provided with between the first pad 1 and the second pad 2, avoid or reduce fluid from the phenomenon of leaking between the first pad 1 and the second pad 2, improve the overall sealing performance of combined type gasket construction.
Mid seal 3 can have structure suitable arbitrarily, as long as it can form linear sealing with the first pad 1 and the second pad 2.Preferably, mid seal 3 can be formed as the ring with circular cross section, to facilitate manufacturing.But the cross section of mid seal 3 also can be other shape, such as oval.
In the using process of combined type gasket construction of the present utility model, owing to being positioned at the squeezing action of the component of gasket construction both sides, first pad 1 and the second pad 2 are pressed in mid seal 3 respectively, thus form linear sealing with mid seal 3.In order to ensure that mid seal 3 can form linear contact lay with the first pad 1 and the second pad 2 when bearing extruding, preferably, mid seal 3 is formed as stiffening ring, and namely mid seal 3 can not produce deformation when bearing active force.But, owing to there is not the material of perfect rigidity in reality, therefore, the larger metallic material of rigidity or resilient nonmetallic material can be used to manufacture mid seal 3.
Above-mentioned resilient nonmetallic material can be such as rubber.Because the resistance to high temperature of nonmetallic material is poor, therefore, the combined type gasket construction be made up of the mid seal 3 of nonmetallic material is applicable to the lower occasion of temperature.
As a kind of preferred implementation of the present utility model, described first pad 1 is formed with the first jut 11 around described through hole 4, described second pad 2 is formed with second jut 21 corresponding with described first jut 11, rely on this two juts, first pad 1 and the second pad 2 form sealing strip respectively, ensures the sealing between component and the first pad 1 and between component and the second pad 2.
Preferably, be formed with cavity 5 between the internal surface of described first jut 11 and the internal surface of described second jut 21, described mid seal 3 is contained in described cavity 5.In this preferred implementation, by dexterously mid seal 3 being arranged in the cavity 5 that formed by the internal surface of the internal surface of the first jut 11 and described second jut 21, mid seal 3 is made to occupy additional space, reduce the spacing of the first pad 1 and the second pad 2, thus the first pad 1 and the second pad 2 can more closely be fitted, further ensure the sealing between the first pad 1 and the second pad 2.
The cross section of the first jut 11 and the cross section of the second jut 21 can be curved.
Preferably, described first pad 1 and described second pad 2 can all be made of metal, to have good mechanical property, and simultaneously can not by the restriction of operating ambient temperature.
Conveniently be installed on component by combined type gasket construction, preferably, as shown in Figure 1, the both sides of described through hole 4 are formed with mounting hole 6 respectively.
Combined type gasket construction of the present utility model may be used for the various occasion needing sealing, such as, be used in motor car engine.For motor car engine, because the pad quantity between engine component is various, very easily occur due to the poorly sealed leakage problem caused, if can not process timely and effectively, will engine performance be affected.Because combined type gasket construction of the present utility model has good overall tightness, therefore, use this combined type gasket construction especially favourable within the engine, that is, described combined type gasket construction is preferably the combined type gasket construction for motor.
Below in conjunction with Fig. 2 and Fig. 3, the working principle according to the combined type gasket construction of preferred implementation of the present utility model is described.
Under normal state (off working state), the first jut 11 and the second jut 21, in circular arc state, have certain preset clearance between mid seal 3 and the internal surface of two juts.In use, due to the squeezing action of combined type gasket construction both sides component, first jut 11 and the second jut 21 produce deformation, form the cross-sectional configuration roughly shown in Fig. 3, now, the outer surface of the first jut 11 contacts with component mating face with the outer surface of the second jut 21, ensures sealing; Meanwhile, the internal surface of the first jut 11 and the internal surface of the second jut 21 and mid seal 3 closely fit together, and form linear sealing, ensure not leak between the first pad 1 and the second pad 2.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.Such as, although the combined type gasket construction of the present utility model shown in accompanying drawing is for double-deck, but still combined type gasket construction of the present utility model can be used in multi-layer gasket.
It should be noted that in addition, each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
