Abstract

The utility model discloses an R neck helical polishing valve. An R neck is provided with helical counter-clockwise radial grains, the grain direction keeps consistent with the airflow direction when the valve works, the spacing width of the R neck helical grains is less than 0.1mm, and the surface coarseness Ra is below 0.5. The valve with the structure has the advantages of improving the discharge resistance of airflow, reducing carbon deposit, enhancing radiating effect, decreasing stress concentration and the like. The service life of products is prolonged.

Description

R cervix helical polishing valve
Technical field
The utility model relates to a kind of engine valve, refers in particular to a kind of R cervix helical polishing valve.
Background technique
The processing mode that engine valve R neck adopts is generally turning processing or grinding, and its cutter trade is that the center is the concentric circle arrangement with the valve axis, and the airflow direction when working with valve differs.The valve that adopts turning processing or grinding is inconsistent because of turning tool marks and airflow direction in the using process meeting, the valve R neck roughness higher (generally reaching Ra3.2) of turning processing particularly, gas-flow resistance is bigger than normal when causing valve work, cause radiating effect poor, the valve carbon distribution is serious, reduce the valve usability, cause valve early failue.
The model utility content
Goal of the invention of the present utility model is to provide a kind of air-flow exhaust resistance that improves, and reduces carbon distribution, strengthens radiating effect, reduces the engine valve that stress is concentrated.
For achieving the above object, the utility model provides a kind of R cervix helical polishing valve, comprise dish portion, R neck, bar portion, rod slot, rod end surface composition, the R neck has the counterclockwise radial lines of spiral, and airflow direction is consistent when ridge orientation and valve work.
Described R cervix helical polishing valve, R cervix helical inter-ridge distance is wide less than 0.1mm.
Described R cervix helical polishing valve is below the R neck surface roughness Ra0.5.
The beneficial effects of the utility model, because of valve R neck has the counterclockwise radial lines of spiral, airflow direction is consistent when ridge orientation and valve work, therefore the air-flow of improvement exhaust resistance is arranged, reduce carbon distribution, strengthen radiating effect, reduce the beneficial effect that stress is concentrated.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the side view of prior art valve.
Fig. 2 is the side view of R cervix helical polishing valve.
Fig. 3 is the plan view of prior art valve.
Fig. 4 is the plan view of R cervix helical polishing valve.
Wherein reference character be 1, dish portion; 2, R neck; 3, bar portion; 4, rod slot; 5, rod end surface; 6, airflow direction.
Embodiment
With reference to Fig. 2, a kind of R cervix helical polishing valve comprises dish portion 1, R neck 2, bar portion 3, rod slot 4, rod end surface 5 compositions, and the R neck has the counterclockwise radial lines of spiral, and airflow direction is consistent when ridge orientation and valve work.
Described R cervix helical polishing valve, R neck 2 spiral inter-ridge distances are wide less than 0.1mm.
Described R cervix helical polishing valve, R neck 2 surface roughness Ra are below 0.5.

Claims (3)
