Abstract
The utility model discloses a sealing structure of a gasket, which comprises a gasket body, wherein the gasket body can be a single-layer plate or a multi-layer plate which is connected together through a connecting point, a sealing hole and a bolt hole are arranged on the gasket body, and a sealing strip is arranged at the sealing hole; the laminated plate is characterized in that one side of the contact surface of at least one layer of the laminated plate at the positions of the sealing holes and the bolt holes and the flange is provided with small sealing hole corrugations and small bolt hole corrugations, and the height of the small corrugations is 0.06-0.13 mm; the sealing area is widened by adding a plurality of small corrugations with slightly low heights between the sealing strip and the hole for auxiliary sealing, and a plurality of small corrugation fixing gaskets are added on the periphery of the bolt hole, so that the phenomenon that the flange is damaged due to the fact that the flange moves and rubs along with the vibration of an engine in the using process is prevented.
Description
The technical field is as follows:
the utility model relates to a gasket sealing technical field, specifically say and an attached gasket seal structure.
Technical background:
along with the continuous improvement of the dynamic performance of automobile parts, the temperature of the exhaust gas of an engine is higher and higher, the sealing performance of a single sealing strip cannot be guaranteed, the influence of the vibration of the engine on an auxiliary gasket is larger and larger, and the auxiliary gasket is damaged due to the fact that the auxiliary gasket vibrates together with a body and moves and rubs between flanges in the using process of the engine.
The utility model has the following contents:
the utility model aims to overcome the defects of the prior art and provide an auxiliary gasket sealing structure; the sealing performance is improved, and the damage of the gasket caused by friction is reduced.
The utility model provides a technical scheme is: an auxiliary gasket sealing structure comprises a gasket body, wherein the gasket body can be a single-layer plate or a multi-layer plate which is connected together through a connecting point, a sealing hole and a bolt hole are formed in the gasket body, and a sealing belt is arranged at the sealing hole; the special point is that one side of the contact surface of at least one layer of the laminate at the positions of the sealing holes and the bolt holes and the flange is provided with small sealing hole corrugations and small bolt hole corrugations, and the height of the small corrugations is 0.06-0.13 mm.
The utility model has the advantages that: 1. after a plurality of small corrugations are added, the defect of the sealing performance of a single sealing strip is overcome, the sealing strip is used as an auxiliary seal, after a flange is fastened by bolts, the sealing strip and the original sealing strip play a sealing role together, and a sealing area is obviously enlarged compared with an original structure; 2. in order to solve the problem that the existing accessory gasket is damaged due to long-term friction between flanges along with the vibration of a body in the use process of an engine, small ripples with different numbers are added on the periphery of a bolt hole, the directions of the ripples are perpendicular to the vibration direction of the engine, the friction can be reduced in the use process of the accessory gasket, and the accessory gasket is prevented from being damaged.
Description of the drawings:
fig. 1 is a schematic front view of the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
The specific implementation mode is as follows:
for a better understanding and appreciation of the invention, reference will now be made in detail to the present invention; the examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, a seal structure of an auxiliary gasket takes a four-layer plate seal structure as an example; sealing holes 8 and bolt holes 9 are respectively arranged on the first layer plate 1, the second layer plate 2, the third layer plate 3 and the fourth layer plate 4, a sealing strip 10 is punched at the sealing holes 8 through a die, and the corrugation height of a single sealing strip is about 0.30mm generally; stamping a sealing belt 10 on a second layer plate 2 and a fourth layer plate 4, and simultaneously stamping a plurality of sealing hole small corrugations 5 and a plurality of bolt hole small corrugations 6, wherein the small corrugations are 0.06-0.13mm in height; and then the four-layer plates are connected together in a manner of spot welding or copper-protection riveting through four connecting points 7 to form the gasket body.
The utility model discloses an auxiliary gasket sealing structure, a sealing strip and small corrugations are arranged on the same set of die, the small corrugations are simultaneously processed and formed when the sealing strip is stamped on a laminate, and a plurality of layers of gaskets are assembled by spot welding or a retainer ring; the sealing area is widened by adding a plurality of small corrugations with slightly low heights between the sealing strip and the hole for auxiliary sealing, and a plurality of small corrugation fixing gaskets are added on the periphery of the bolt hole, so that the phenomenon that the flange is damaged due to the fact that the flange moves and rubs along with the vibration of an engine in the using process is prevented.
