Abstract
The utility model discloses a cylinder head cover component, which comprises a cover body which is a cavity structure with one surface opened. The opened surface is a seal surface, and a plurality of lug bosses are arranged on the seal surface. A circle of seal edges is arranged at the edge of the seal surface, a cylinder head cover gasket is embedded and sheathed with the seal edges, and the cover body is provided with a bolt which can be connected with a cylinder head. The cylinder head cover component has the advantages of favorable sealing and damping effect, convenient arrangement, low manufacture cost and convenient maintenance.
Description
Technical field
The utility model relates to a kind of sealing configuration that covers class, relates in particular to a kind of valve mechanism cover assembly that is used for the engine cylinder cap sealing.
Background technique
Development along with diesel technology, exhaust brake, the pump nozzle, new and high technologies such as common rail constantly are applied on the diesel engine, wherein a lot of component all are arranged on the cylinder head, meanwhile, the manufacturer of diesel engine makes and after cost in order to reduce, diesel engine using the form of one cylinder (cylinder) a lid (cylinder head), it is very compact that the structure of the cylinder head sub-assembly of diesel engine becomes, thereby make that traditional valve mechanism cover sealing configuration is difficult to arrange, influence its sealing, the effect of damping noise reduction, and the valve mechanism cover gasket compression is excessive, causes the damage of pad easily.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, a kind of sealing, good damping effect is provided, avoids the excessive valve mechanism cover assembly of valve mechanism cover gasket compression.
For solving the problems of the technologies described above, the utility model provides a kind of valve mechanism cover assembly, comprise cover body, described cover body is unlimited cavity structure for one side, the one side that should open wide is a sealing surface, is provided with several boss on described sealing surface, is provided with a circle sealing strip at the edge of described sealing surface, be inlaid with the valve mechanism cover pad on described sealing strip, described cover body is provided with the bolt that can be connected with cylinder head.
The height of the end face of described boss is a little more than the height of described sealing strip upper edge; The apical side height of described valve mechanism cover pad is a little more than the apical side height of described boss.
Described valve mechanism cover pad is an elastic material.The preferred rubber material that adopts.
Described boss is provided with 4; Described bolt is provided with 4.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, owing to be to utilize the elastic compression of valve mechanism cover pad to reach sealing effect, sealing surface can adopt seal form such as single line, two-wire and face flexibly, sealing, good damping effect.
2, the sealing surface of valve mechanism cover and cylinder head can be designed into very little, arrangement convenience.
3, low cost of manufacture, easy to maintenance.
Description of drawings
Fig. 1 is that valve mechanism cover assembly of the present utility model is installed in the schematic representation on the cylinder head.
Fig. 2 is the local enlarged diagram of valve mechanism cover of the present utility model.
Fig. 3 is a valve mechanism cover assembly explosive view of the present utility model.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-cylinder head; 2-valve mechanism cover pad; 3-valve mechanism cover bolt;
The 5-cover body; The 6-sealing surface; The 7-boss; The 8-sealing strip.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
As shown in Figure 1, the utility model valve mechanism cover assembly, comprise cover body 5, cover body 5 is unlimited cavity structure for one side, the one side that should open wide is a sealing surface 6, is provided with several boss 7 on sealing surface 6, is provided with a circle sealing strip 8 at the edge of sealing surface 6, inlay on sealing strip 8 and be with valve mechanism cover pad 2, valve mechanism cover pad 2 is enclosed within on the sealing strip 8 of cover body 5 in advance.Valve mechanism cover pad 2 is an elastic material.The preferred rubber material that adopts.Cover body 5 is connected on the engine cylinder cap 1 by 4 valve mechanism cover bolts 3 (for standard bolt) with cylinder head 1.
Wherein, boss 7 is provided with 4, and the height of the end face of boss 7 is a little more than the height of sealing strip 8 upper edges; The apical side height of valve mechanism cover pad 2 is a little more than the apical side height of boss 7.
When cylinder head bolt 3 make-up torques, boss 7 end faces of valve mechanism cover 3 and cylinder head 1 end face are fitted, at this moment form certain clearance between the end face of the sealing strip of valve mechanism cover 3 and cylinder head 1 end face, valve mechanism cover pad 2 has been subjected to compression simultaneously, sealing strip and cylinder head 1 end face to gas hood body 5 have produced reaction force, thereby have reached seal action.
Four boss being cast above the utility model cover body 5 have limited the precession amount of valve mechanism cover bolt 3, have avoided valve mechanism cover 5 sealing strips excessive to the pressure of valve mechanism cover pad 2, cause valve mechanism cover pad 2 impaired.The boss end face of cover body 5 exceeds the certain size in sealing strip upper edge, has played the decrement effect of control cylinder housing pad 2.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
