Abstract
The utility model discloses a cylinder cover for a gas engine, which belongs to the technical field of gas engines. The cylinder cover mainly comprises a cylinder cover body, wherein an installation channel for installing an ignition coil is arranged on the cylinder cover body and is corresponding to the position of the mounting hole of a spark plug on the cylinder body of the gas engine. The cylinder cover solves the technical problem that the service life of the ignition coil for the gas engine is short and is widely used for manufacturing the gas engine.
Description
Technical field
The utility model relates to the gas engine technical field, relates in particular to a kind of valve mechanism cover that is used for gas engine.
Background technique
At present, the spark coil of gas engine all is mounted on the cylinder block of gas engine, and the outside of cylinder is provided with a valve mechanism cover again; with protection cylinder and spark coil; during use, cylinder piston carries out stroke and drawback movement, and the heat of generation makes the lubricant oil volatilization; therefore; lubricant oil fog concentration within the valve mechanism cover is higher, and spark coil is among the encirclement of lubricant oil fog fully, uses for a long time; spark coil is suffered erosion, and reduce working life greatly.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of gas engine valve mechanism cover, to solve gas engine spark coil low technical problem in working life.
For solving the problems of the technologies described above, the technical solution of the utility model is: the gas engine valve mechanism cover, comprise the valve mechanism cover body, described valve mechanism cover body is provided with the installation passage that is used for the mounting points fire coil, and described installation passage is corresponding with the spark plug mounting hole position on the gas engine cylinder block.
As a kind of improvement, be embedded with the protecting cover that is used to wrap up described spark coil in the described installation passage.
As further improvement, described protecting cover extends in the described spark plug mounting hole.
After having adopted technique scheme, the beneficial effects of the utility model are: because the valve mechanism cover body is provided with the installation passage that is used for the mounting points fire coil, make spark coil be installed on the valve mechanism cover body and also can expose the valve mechanism cover body, therefore spark coil is not to be in fully among the encirclement of lubricant oil fog, has prolonged the working life of spark coil.
Because install in the passage and be embedded with the protecting cover that is used to wrap up spark coil, protecting cover extends in the spark plug mounting hole, makes spark coil and lubricant oil fog isolate fully, has further prolonged the working life of spark coil.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the utility model embodiment's user mode figure;
Among the figure: 1, valve mechanism cover body, 11, passage is installed, 2, spark coil, 3, the gas engine cylinder block, 31, spark plug mounting hole, 4, protecting cover.
Embodiment
As depicted in figs. 1 and 2, a kind of gas engine valve mechanism cover, mainly comprise valve mechanism cover body 1, described valve mechanism cover body 1 is provided with the installation passage 11 that is used for mounting points fire coil 2, described installation passage 11 is corresponding with spark plug mounting hole 31 positions on the gas engine cylinder block 3, and the dead in line of passage 11 and spark plug mounting hole 31 is installed usually.Be embedded with the protecting cover 4 that is used to wrap up described spark coil 2 in the described installation passage 11, described protecting cover 4 extends in the described spark plug mounting hole 31, and according to conventional design, described protecting cover 4 is designed to steel bushing.
During use, valve mechanism cover body 1 is fixedly installed on the gas engine cylinder block 3, spark coil 2 can directly be inserted into from the installation passage 11 at valve mechanism cover body 1 top the spark plug mounting hole 31 on the gas engine cylinder block 3, owing to install between passage 11 and the spark plug mounting hole 31 and be provided with protecting cover 4, make the lubricant mist compression ring border in spark coil 2 and the valve mechanism cover body 1 isolate fully, intercepted of the erosion of lubricant oil fog, prolonged the working life of spark coil 2 greatly spark coil 2.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
Claims (3)
1. the gas engine valve mechanism cover comprises the valve mechanism cover body, it is characterized in that: described valve mechanism cover body is provided with the installation passage that is used for the mounting points fire coil, and described installation passage is corresponding with the spark plug mounting hole position on the gas engine cylinder block.
2. gas engine valve mechanism cover as claimed in claim 1 is characterized in that: be embedded with the protecting cover that is used to wrap up described spark coil in the described installation passage.
