Description
Technical field
The utility model is related to a kind of cylinder head and its and cylinder head sealing structure more particularly to a kind of floated gas
Cylinder head cover and its sealing structure.
Background technology
Engine cylinder cap rubber gasket has the physical properties such as good high temperature resistant, oil resistant, weather-proof, has one preferably
Sealing reliability has preferably played the unique sealing potential quality of rubber seal, and existing oneself becomes the mainstream of engine cylinder cap sealing.
In terms of main engine plants' installation, operating condition, engine air cylinder cap rubber gasket assembly process process is good, and production efficiency is high, can be full
The needs of sufficient modern production, market failure feedback rates are extremely low, Reusability.
First of cylinder head and most basic function are to cover and blanket gas cylinder cap, machine oil are maintained at internal, simultaneously
By contaminants such as dirt and moistures in outer.Second function is by machine oil and air insulated.In the operation process of engine
In can form mist of oil.The colder inner surface of valve mechanism cover assembles collection mist of oil, condenses machine oil and backs downward into machine oil shell.Cylinder head
Cover also bears the responsibility of crankcase ventilation.When piston moves in the cylinder, engine interior can compact pressure.If put no
Reason, this pressure can make each seal leakage, engine efficiency caused to reduce.It can be seen that the use occasion of gasket is complicated severe,
Using the connection mode of traditional cylinder head and valve mechanism cover so that gasket is chronically at the severe situation of deformation, accelerates material
Matter aging and noise is big between cylinder head and valve mechanism cover.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of reliable floated gas for sealing, being capable of noise reduction
Cylinder head cover and its sealing structure.
The utility model is to solve above-mentioned technical problem by the following technical programs：The utility model includes valve mechanism cover
Cover body, several stop collars；The valve mechanism cover cover body includes several connecting holes, and the stop collar is hollow structure, and the company of insertion
It connects in hole, and stop collar bottom surface protrudes valve mechanism cover cover body bottom surface.
Preferably, the stop collar is cylindrical tube shape, and including stack shell, scrap (bridge), stack shell top is equipped with scrap (bridge), and the scrap (bridge) is taken
On valve mechanism cover cover body.
Preferably, the stack shell outer profile diameter is equal to connection bore dia.
Preferably, internal thread is equipped in the stack shell.
Preferably, the scrap (bridge) and stack shell are orthogonal.
Preferably, the scrap (bridge) top surface is plane, the stop collar bottom surface is plane.
The utility model also provides a kind of sealing structure using the floated valve mechanism cover, including cylinder head, cylinder head
Cover, seal washer, several fastening bolts, the seal washer are embedded in valve mechanism cover bottom surface, and the valve mechanism cover is by several tight
Fixing bolt is connected in cylinder head, and there are gaps between the valve mechanism cover and cylinder head.
Preferably, the stop collar bottom surface is against top surface of cylinder cover.
The utility model has the following advantages compared with prior art：The utility model protrudes valve mechanism cover using stop collar
Mode so that there are certain intervals between cylinder head and valve mechanism cover, rub between finite reduction cylinder head and valve mechanism cover, drop
Low noise；Furthermore rubber gasket keeps most good state, prolongs the service life, and ensures leakproofness, reduces oil leakage phenomenon；Most
Afterwards, stop collar replacement simple in structure, easy to install, easy, good appearance.

Specific embodiment
Elaborate below to the embodiment of the utility model, the present embodiment using technical solutions of the utility model before
It puts and is implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As shown in Figs. 1-2, the present embodiment includes 2 cover body of valve mechanism cover, several stop collars；The valve mechanism cover cover body includes
Several connecting holes, the stop collar 5 is hollow structure, and is inserted into connecting hole, and stop collar bottom surface protrudes 2 cover body of valve mechanism cover
Bottom surface.The stop collar 5 is cylindrical tube shape, and including stack shell 51, scrap (bridge) 52,51 top of stack shell is equipped with scrap (bridge) 52, the scrap (bridge) 52
It rides on 2 cover body of valve mechanism cover.The 51 outer profile diameter of stack shell is equal to connection bore dia.Interior spiral shell is equipped in the stack shell 52
Line.The scrap (bridge) 51 and stack shell 52 are orthogonal.51 top surface of scrap (bridge) is plane, 5 bottom surface of the stop collar is plane.
The utility model also provides a kind of sealing structure using the floated valve mechanism cover, including cylinder head 1, cylinder head
Cover 2, seal washer 3, several fastening bolts 4, the seal washer 3 is embedded in 2 bottom surface of valve mechanism cover (as shown in Figure 3), described
Valve mechanism cover 2 is connected to by several fastening bolts 4 in cylinder head 1, and there are gaps between the valve mechanism cover 2 and cylinder head 1.Institute
It states 5 bottom surface of stop collar and is against top surface of cylinder cover.
The course of work of the utility model is as follows：
Seal washer 3 is embedded in 2 bottom surface of valve mechanism cover, stop collar 5 is inserted into 2 connecting hole of valve mechanism cover, by fastening bolt 4
It is screwed into, fastening valve mechanism cover 2 and cylinder head 1 complete installation process.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
