Abstract
The invention relates to a stepped bar type valve which comprises a valve body, a dovetail groove and a valve rod. The valve rod of the valve is of a stepped shaft type structure, a thick shaft is arranged in the middle of the valve rod, and the step face is designed to be of a dovetail groove type structure. The radius ratio of a stepped shaft of the valve rod is 1:1.1, the sliding contact face of the valve rod and a valve guide pipe is arranged to be a thick shaft face, and the oblique angle of the dovetail groove ranges from 30 degrees to 45 degrees. The valve rod is designed to be of the stepped shaft type structure, and a dovetail notch is designed 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 stepped bar type valve has the beneficial effects of being simple in structure, reducing product quality and meanwhile reducing production cost.
Description
Technical field
The present invention relates to automobile air valve field, particularly relate to a kind of stepped rod type 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 ladder axis structure, and at cascaded surface, it is designed to dovetail groove orifice, improve the service life of valve, avoid the carbon distribution damage to valve, solve the phenomenon of the overheated carbon distribution of valve guide bushing, 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, it is provided that a kind of stepped rod type valve, by valve stem being designed to ladder axis structure, and at cascaded surface, being designed to dovetail groove orifice, the problem solving the overheated carbon distribution of valve guide bushing.
A kind of stepped rod type valve, including valve, dovetail groove, valve stem, it is characterised in that the valve stem of described valve is ladder axis structure, the medium position of described valve stem is thick axle, is designed to dovetail groove type structure at cascaded surface.
Further, the radius ratio of the multidiameter of described valve stem is 1:1.1, makes valve stem and valve guide bushing sliding contact surface be set to thick axial plane, in the case of ensureing valve stable operation, make thin axle be in idle contactless, improve the speed of service and the service life of valve.
Further, the angle of bevel of described dovetail groove is between 30 °-45 °, and the dovetail groove of setting is used for removing the carbon distribution that valve guide bushing is formed with valve stem.
The present invention provides a kind of stepped rod type valve, it has the beneficial effect that by valve stem is designed to ladder axis structure, and at cascaded surface, it is designed to dovetail groove orifice, improve the service life of valve, avoid the carbon distribution damage to valve, solve the phenomenon of the overheated carbon distribution of valve guide bushing, there is simple in construction, while reducing product weight, reduce production cost.
Accompanying drawing explanation
The present invention is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute any limitation of the invention.
Fig. 1 is the structural representation of a kind of stepped rod type valve of the present invention；
In figure, 1-valve, 2-dovetail groove, 3-valve stem.
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 it is shown in figure 1, a kind of stepped rod type valve, including valve 1, dovetail groove 2, valve stem 3, it is characterised in that the valve stem 3 of described valve 1 is ladder axis structure, and the medium position of described valve stem 3 is thick axle, is designed to dovetail groove 2 formula structure at cascaded surface.
Wherein, the radius ratio of the multidiameter of valve stem 3 is 1:1.1, makes valve stem 3 and valve guide bushing sliding contact surface be set to thick axial plane, in the case of ensureing valve 1 stable operation, makes thin axle be in idle contactless, improve the speed of service and the service life of valve 1.
Wherein, the angle of bevel of dovetail groove 2 is between 30 °-45 °, and the dovetail groove 2 of setting is used for removing the carbon distribution that valve guide bushing is formed with valve stem 3.
The present invention is a kind of stepped rod type valve, by valve stem being designed to ladder axis structure, and at cascaded surface, it is designed to dovetail groove orifice, improve the service life of valve, avoid the carbon distribution damage to valve, solve the phenomenon of the overheated carbon distribution of valve guide bushing, there is simple in construction, while reducing product weight, reduce 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.
