Abstract
The utility model relates to the technical field of automobile accessories, in particular to a valve guide pipe convenient to install. The valve guide pipe convenient to install comprises a straight-pipe-shaped pipe body, cutting faces I are symmetrically arranged on outer walls of end ports of two ends of the pipe body, cutting faces II are symmetrically arranged on inner walls of the end ports of two ends of the pipe body, inclined angles of the cutting faces I are between 10 to 20 degrees, and inclined angles of the cutting faces II are between 25 to 45 degrees. The valve guide pipe is simple in structure, convenient to assemble and tight to assemble. In addition, when the valve guide pipe is pressed into an air cylinder cover, a user needn't distinguish the installation direction.
Description
Technical field
The utility model relates to auto parts machinery microcatheter technology field, especially a kind of valve guide bushing of being convenient to install.
Background technique
Existing automotive engine valves conduit generally adopts the form of tubulose, one end of this valve guide bushing is installed in the conduit bottom outlet of cylinder head, the other end is used for valve oil seal is installed, and valve stem is to-and-fro motion in valve guide bushing, and this valve guide bushing two ends are asymmetric, and be provided with for the groove that valve oil seal is installed, cause when valve guide bushing is installed, easily that valve guide bushing is anti-loaded, and because weak in intensity upper latch notch position, easy-rupturing leaks.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of simple in structure, the valve guide bushing of being convenient to install.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of valve guide bushing of being convenient to install, body with Straight, described body two ends port outer wall is provided with the tangent plane I symmetrically, body two ends port inner wall is provided with the tangent plane II symmetrically, the angle of inclination of described tangent plane I is the 10-20 degree, and the angle of inclination of tangent plane II is the 25-45 degree.
Further, the angle of inclination of described tangent plane I is 15 degree, and the angle of inclination of tangent plane II is 30 degree.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to assembly, do not need to differentiate installation direction, fitting tight when being pressed into cylinder head.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
