Abstract
The utility model provides an engine cylinder gasket adopting a bonding and coating structure. The engine cylinder gasket comprises a cylinder gasket body, wherein a plurality of corrugated ribs are pressed on a core plate of the cylinder gasket body, a sealing material is arranged between the adjacent corrugated ribs on the upper and lower surfaces of the core plate and is fixed on the core plate by bonding, a thin metal ring is arranged on the upper surface of the core plate adjacent to the sealing material, a metal protection ring is arranged on a cylinder opening sealing part of the cylinder gasket body, a water hole and an oil duct hole of the cylinder gasket body are provided with a sealing layer, and an organic silicon coating is coated on the surfaces of the cylinder gasket body. According to the engine cylinder gasket adopting the bonding and coating structure, the body is formed by bonding two layers of sealing materials and the thick core plate, so that the body is high in strength and engine pressure resistance and is not easily broken; a cylinder opening adopts a comprehensive sealing structure comprising stainless steels, the reinforced thin ring and the corrugated ribs of the core plate, so that the sealing problem of the cylinder gasket at a lintel of an engine, whose minimum width is 4mm, can be solved, and the sealing requirement on explosion pressure of the engine can be met.
Description
Technical field
The utility model relates to a kind of head gasket, especially a kind of cylinder pad of bonding bag complex structure.
Background technique
The middle low power diesel oil of domestic production at present, sale does not have asbestos (graphite) bag replica head gasket, and its body adopts two-layer no asbestos (graphite) and single-layer metal spurt to be composited the structure that the cylinder mouth adopts metal sheet punching press and steel traveler bag to form again.Its characteristics: the engine cylinder beam place width of making a slip of the tongue is too small, when its width reaches 4～6mm, can only adopt single steel traveler even not have steel traveler bag complex structure, when engine flare pressure surpasses 100bar, occurs easily revealing.
Summary of the invention
The purpose of the utility model provides a kind of cylinder pad of bonding bag complex structure, can effectively solve the head gasket sealing of the minimum 4mm in motor lintel place, satisfies the sealing of engine flare pressure up to 130bar simultaneously.
In order to solve the problems of the technologies described above; The technological scheme of the utility model is following: a kind of cylinder pad of bonding bag complex structure, comprise the head gasket body, and it is characterized in that: be pressed with many ripple muscle on the central layer of said head gasket body; Be provided with sealing material between the upper surface of central layer and the lower surface adjacent corrugations muscle; Sealing material is through being adhesively fixed on the central layer, and the part adjacent with the upper surface sealing material of central layer is provided with the metal foil ring, and the seal with annular groove position of head gasket body is provided with the metal guard ring; The water hole of head gasket body and oil channel hole place are provided with sealing layer, and the surface of head gasket body scribbles organosilicon coating.
Improvement to technique scheme: said sealing material is no Ashestos plate or graphite sheet.
Further improvement to technique scheme: the sealing layer at place, said water hole is to be coated on the sheet copper on the opening of water hole or is to be printed on the sealer on the opening of water hole.
Further improvement again to technique scheme: the sealing layer at said oil channel hole place is to be coated on the sheet copper on the oil channel hole opening or is to be printed on the sealer on the oil channel hole opening or to be rubber skeleton.
Further improvement to technique scheme: the stainless steel material that said metal guard ring is thickness 0.25～0.28mm is stamped to form, and said central layer is the steel plate of thickness 0.5～0.8mm.
Beneficial effect:
Use the cylinder pad of the described bonding bag complex structure of the utility model, body adopts two-layer no asbestos (or graphite) to form with thick central layer is bonding, and body intensity is high, and anti-engine pressure is high, and body is easy-rupturing not; The cylinder mouth adopts stainless steel, strengthens thin ring, central layer ripple muscle comprehensive sealing structure, effectively solves the head gasket sealing structure in the zone of the minimum width 4mm of motor lintel place, can satisfy the seal request of engine flare pressure up to 130bar; Water hole, oil channel hole adopt strengthens copper sheet and printing and sealing glue enhancing sealing.
