Abstract
The utility model provides a gas valve of an engine. The gas valve of the engine comprises a gas valve rod, a gas valve disc cone face portion, and a gas valve head portion, wherein a cone face angle of the disc cone face portion is 20 degrees. In the gas valve of the engine, the traditional gas valve structure is reformed and the cone face angle of the disc cone face portion is reduced to 20 degrees. The modified art enables cone face normal force formed by the collision of the gas valve and a gas valve seat ring in gas valve work to be further reduced. At the same time, due to the fact that the cone face normal force is reduced, plastic deformation of the gas valve disc cone face is reduced and a slippage between the gas valve and the gas valve seat ring can be reduced. The utility model also provides an engine provided with the gas valve.
Description
Technical field
The utility model relates to technical field of engines, more particularly, relates to a kind of valve of motor, and the utility model also relates to a kind of motor with above-mentioned valve.
Background technique
Along with the development of engine technology, valve plays critical effect always in engine valve actuating mechanism, and valve often is related to the traffic capacity of sealing, air-flow of engine chamber and cooling etc.The valve of traditional motor generally comprises valve stem, the several parts of valve head gentle door dish conical surface section, and valve bears very large impulsive load in the course of the work, at high temperature works, and the lubrication and cooling condition is very poor.Therefore, so abominable working environment is had higher requirement to valve, and in order to adapt to this working environment, valve should have enough intensity, rigidity and stability, has again good heat resistance, wear resistance and corrosion stability and sealing reliable.
In conventional art, the conical surface angle great majority of valve retainer conical surface section are 45 °, because the existence of inertial impact force, the collision meeting of valve air valve seat ring in the process of closing produces larger frictional force at valve retainer conical surface section place, normal force is also larger, and the wearing and tearing between valve and the air valve seat ring are also larger, and the accumulation meeting along with the time produces plastic deformation at valve retainer conical surface place like this, simultaneously along with the increasing of wearing and tearing, can produce relative slight skew between valve and the air valve seat ring.
Along with the development of material technology and updating of air valve structure, in the prior art the structure to valve be optimized, have the valve-face angle by 45 ° of situations that change 30 ° into, the improvement of this kind structure so that the conical surface normal force when impacting between valve and the air valve seat ring relatively reduce, the plastic deformation of valve retainer conical surface section also can diminish, can produce relative slight shift phenomenon between valve and the air valve seat ring also can alleviate, the plastic deformation of the valve retainer conical surface also still exists, and the wearing and tearing of air valve seat ring are still comparatively obvious.
Therefore, how existing air valve structure is improved, further to reduce motor in the course of the work, the skew between the wearing and tearing between valve and the air valve seat ring and valve and the air valve seat ring is present those skilled in the art's problem demanding prompt solution.
The model utility content
In view of this, the utility model provides a kind of valve of motor, further to reduce motor in the course of the work, the skew that produces between the wearing and tearing between valve and the air valve seat ring and valve and the air valve seat ring.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of valve of motor comprises valve stem, valve retainer conical surface section and valve head, and the face angle of described valve retainer conical surface section is 20 °.
Preferably, in the valve of above-mentioned motor, described valve adopts X45CrSi93 to make.
Preferably, in the valve of above-mentioned motor, described valve stem, valve retainer conical surface section and valve head have the heat treatment surface.
In the valve of the motor that the utility model provides, traditional air valve structure is improved, the conical surface angle of valve retainer conical surface section is reduced to 20 °, this kind improves so that the conical surface normal force of colliding with air valve seat ring during valve work more reduces, while is owing to normal force reducing, the plastic deformation of valve retainer conical surface section also diminishes, and the slippage between valve and air valve seat ring also diminishes.
Based on the above-mentioned valve that provides, the utility model also provides a kind of motor with valve of said structure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in the utility model embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the valve that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structure for amplifying schematic representation of valve retainer conical surface section 4 among Fig. 1.
Among upper Fig. 1-2:
Embodiment
The utility model embodiment provides the valve of motor, has further reduced motor in the course of the work, the skew that produces between the wearing and tearing between valve and the air valve seat ring and valve and the air valve seat ring.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
Please refer to Fig. 1-2, the utility model embodiment provides a kind of valve of motor, comprises valve stem 1, valve retainer conical surface section 4 and valve head 3, and the face angle B of valve retainer conical surface section is 20 °.In the valve of the motor that the utility model provides, traditional air valve structure is improved, the conical surface angle of valve retainer conical surface section 4 is reduced to 20 °, this kind improves so that the conical surface normal force of colliding with air valve seat ring 2 during valve work more reduces, while is owing to normal force reducing, the plastic deformation of valve retainer conical surface section 4 also diminishes, and the slippage that valve and air valve seat ring are 2 also diminishes.
In order further to optimize technique scheme, the valve of above-described embodiment motor preferably adopts X45CrSi93 to make, and the surface of above-mentioned engine valve heat-treated, be that valve stem, valve retainer conical surface section and valve head have the heat treatment surface, compare with traditional valve material, the valve that adopts above-mentioned material to make has comparatively significantly heat resistance, corrosion resistance, increases wear resistance.
The valve that provides based on above-described embodiment, the utility model embodiment also provides a kind of motor with above-mentioned valve, because the beneficial effect of this motor valve after being improved by above-described embodiment brings, therefore, concrete beneficial effect please refer to mentioned above getting final product, than repeating no more.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
