Abstract
The invention relates to a multi-notch type valve which comprises a valve body, strip-shaped grooves and a valve rod. The strip-shaped grooves are formed in the valve rod of the valve and formed in the circumference of the valve rod. The cross section of the valve rod is structurally in a plum blossom shape. A transverse notch of each strip-shaped groove is a in a fan shape. The multiple strip-shaped grooves are formed. The fan angle ranges from 45 degrees to 80 degrees. The valve rod is designed to be of a stepped shaft type structure, and the dovetail notches are formed in the step face, so that the service life of the valve is prolonged, the damage of carbon deposition to the valve is avoided, and the phenomenon that a valve guide pipe is too hot to cause carbon deposition is eliminated; and the multi-notch type valve has the beneficial effects of being simple in structure, reducing product weight and meanwhile reducing production cost.
Description
Technical field
The present invention relates to automobile air valve field, particularly relate to a kind of multi-notch formula valve.
Background technology
The effect of valve (Valve) is to be responsible for specially in electromotor inputting fuel and discharging waste gas, conventional engines each cylinder only one of which inlet valve and an exhaust valve, this design structure is relatively easy, cost is relatively low, easy to maintenance, low-speed performance is preferable, and shortcoming is that power is difficult to improve, and during the highest rotating speed, charging efficiency is low, performance is more weak.In order to improve intake and exhaust efficiency, the many Valves Technology of the most employings, the most each cylinder arrangement has 4 valves (also to have single cylinder 3 or the design of 5 valves, principle is the same, electromotor such as Audi A6), 4 cylinders are exactly altogether 16 valves, and " 16V " that we are frequently seen in automobile data means that electromotor totally 16 valves.This many air valve structures easily form compact combustor, and fuel injector is arranged in central authorities, so can make air-fuel mixture gas firing more rapidly, evenly, and weight and the aperture of each valve suitably reduce, and make the speed of valve opening or Guan Bi faster.
Air valve structure for prior art, valve belongs to guide rod type slide construction, Integral air valve pole face needs to carry out sliding friction, valve motion speed can be caused the slowest, air inlet or efficiency of giving vent to anger to electromotor are slower, and the energy needing waste bigger that moves up and down of valve, energy utilization rate is relatively low, therefore, by valve stem being designed to surface angle slot type structure, solve the phenomenon of the overheated carbon distribution of valve guide bushing, and improve slip efficiency, there is simple in construction, while reducing product weight, reduce production cost.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of multi-notch formula valve is provided, by valve stem being designed to surface angle slot type structure, solve the phenomenon of the overheated carbon distribution of valve guide bushing, and improve slip efficiency, there is simple in construction, while reducing product weight, reduce production cost.
A kind of multi-notch formula valve, including valve, bar-shaped trough, valve stem, the valve stem of described valve is provided with bar-shaped trough, and described bar-shaped trough is arranged on the circumference of valve stem, and the cross-sectional structure of described valve stem is plum blossom-shaped, and the transverse notch of described bar-shaped trough is fan-shaped.
Further, the number of described bar-shaped trough is multiple, and fan angle, between 45 °-80 °, by the surface of valve stem is set as notch type surface, improves the sliding capability of valve, is beneficial to heat radiation.
The present invention provides a kind of multi-notch formula valve, and it has the beneficial effect that by valve stem is designed to surface angle slot type structure, solves the phenomenon of the overheated carbon distribution of valve guide bushing, and improve slip efficiency, there is simple in construction, while reducing product weight, reduce production cost.

Detailed description of the invention
In order to make the object of the invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of multi-notch formula valve, including valve 1, bar-shaped trough 2, valve stem 3, it is characterized in that, the valve stem 3 of described valve 1 is provided with bar-shaped trough 2, described bar-shaped trough 2 is arranged on the circumference of valve stem 3, and the cross-sectional structure of described valve stem 3 is plum blossom-shaped, and the transverse notch of described bar-shaped trough 2 is fan-shaped.
Wherein, the number of bar-shaped trough 2 is multiple, and fan angle, between 45 °-80 °, by the surface of valve stem 3 is set as notch type surface, improves the sliding capability of valve 1, is beneficial to heat radiation.
The present invention is a kind of multi-notch formula valve, by valve stem 3 is designed to surface angle slot type structure, solves the phenomenon of the valve 1 overheated carbon distribution of conduit, and improves slip efficiency, have simple in construction, while reducing product weight, reduces production cost.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.
