Background technique
Cylinder head gasket is the important spare part of motor; It places and is used for canned motor between the cylinder block and head; In order to avoid fluids such as combustion gas, oil (oiling agent) and freezing mixture overflow, be a kind of multi-functional connection and sealed member, the stable of engine performance played an important role.Yet existing cylinder head gasket generally only adopts the form of cylinder mouth retain sealing to come the sealed high pressure combustion gas in this zone of combustion chamber hole sealing; This cylinder head gasket poor sealing performance when reality is used that adopts the retain sealing of cylinder mouth; Often occur to have satisfied the needs of available engine towards the cylinder phenomenon.
The model utility content
The purpose of the utility model provides a kind of compound cylinder head gasket of dual combined seal structure, and it is mainly used in various petrol engine, LD-diesel; Rational in infrastructure, sealing is reliable, again nontoxic pollution-free; Environmental, greatly improved engine reliability and durability.
The purpose of the utility model is to realize through following technological scheme:
A kind of compound cylinder head gasket of dual combined seal structure comprises shim body, and the middle part of said shim body evenly is provided with some combustion chamber holes; The edge of combustion chamber hole is provided with cylinder mouth guard ring; The two ends of cylinder mouth guard ring are connected with shim body secondary flange, and are provided with the steel wire ring between cylinder mouth guard ring and the shim body, and the left and right sides of said combustion chamber hole is respectively equipped with the bolt hole of symmetry; The bottom side of combustion chamber hole is provided with positioning hole; The top side of combustion chamber hole is provided with the cooling liquid hole, is connected with tappet hole seal ring between the edge at the edge in cooling liquid hole and shim body top, is provided with tappet hole and oilhole in the seal ring of tappet hole; The middle part of said shim body and the edge of bottom are provided with pad periphery sealing strip, and the two ends and the tappet hole seal ring of pad periphery sealing strip are tightly connected; Said cooling liquid bore edges place is provided with cooling liquid hole guard ring; The edge of said oilhole is provided with the oilhole guard ring.
The beneficial effect of the utility model is: good airproof performance, good reliability, long service life and greatly improved the reliability and the durability of motor.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the compound cylinder head gasket of the described a kind of dual combined seal structure of the utility model embodiment;
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure:
1, shim body; 2, combustion chamber hole; 3, cylinder mouth guard ring; 4, steel wire ring; 5, bolt hole; 6, positioning hole; 7, cooling liquid hole; 8, tappet hole seal ring; 9, tappet hole; 10, oilhole; 11, pad periphery sealing strip; 12, cooling liquid hole guard ring; 13, oilhole guard ring.
Embodiment
Shown in Fig. 1-2; The compound cylinder head gasket of the described a kind of dual combined seal structure of the utility model embodiment comprises shim body 1, and the middle part of said shim body 1 evenly is provided with some combustion chamber holes 2; The edge of combustion chamber hole 2 is provided with cylinder mouth guard ring 3; The two ends of cylinder mouth guard ring 3 are connected with shim body 1 secondary flange, and are provided with steel wire ring 4 between cylinder mouth guard ring 3 and the shim body 1, and the left and right sides of said combustion chamber hole 2 is respectively equipped with the bolt hole 5 of symmetry; The bottom side of combustion chamber hole 2 is provided with positioning hole 6; The top side of combustion chamber hole 2 is provided with cooling liquid hole 7, is connected with tappet hole seal ring 8 between the edge at the edge in cooling liquid hole 7 and shim body 1 top, is provided with tappet hole 9 and oilhole 10 in the tappet hole seal ring 8; The middle part of said shim body 1 and the edge of bottom are provided with pad periphery sealing strip 11, and the two ends and the tappet hole seal ring 8 of pad periphery sealing strip 11 are tightly connected; Said cooling liquid hole 7 edges are provided with cooling liquid hole guard ring 12; The edge of said oilhole 10 is provided with oilhole guard ring 13.
During actual production, the material of shim body 1 adopts metal asbestos, metal with high temperature resistant, corrosion-resistant, good rebound elasticity and stable chemical characteristics not to have asbestos (or metallic graphite carbon) composite board material.
During concrete the use, the edge of combustion chamber hole 2 adopts dual combined seal structure, at first selects for use steel wire ring 4 as the sealing of first road, forms metal strong sealing structure; Secondly, cylinder mouth guard ring 3 is carried out the secondary flange be connected, further increase its sealing surface and press, especially under heating status, form the high elasticity sealing, sealability is greatly improved with shim body 1.And because cooling liquid and lubricant oil have pressure; So tappet hole 9 and oilhole 10 are surrounded through tappet hole seal ring 8; Strengthen the sealing and the sealing reliability of guaranteeing oilhole 10 of tappet hole 9 oil returns; Adopt pad periphery sealing strip 11 to surround simultaneously, increase the balance of shim body 1 active force along shim body 1 edge and tappet hole seal ring 8.The utility model is mainly used in various petrol engine, and LD-diesel is rational in infrastructure, and sealing is reliable, and nontoxic pollution-free is environmental again, has greatly improved engine reliability and durability.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within the protection domain of the utility model.
