Abstract
The invention provides a novel hollow sodium filled valve. The novel hollow sodium filled valve is composed of a plate part, a rod body and a plug, wherein a hollow part which moves along the axial direction is arranged in the rod body; and the hollow part is filled with metal sodium materials of which the melting point is 97.81 DEG C. When the valve works, the temperature increases rapidly, and the metal sodium is converted from solid into liquid; liquid sodium scours the plate part and the rod body of the valve continuously to transfer the heat of the plate part and the neck part of the valve out rapidly, so that radiation performance of the valve is increased, and temperature can be reduced by about 100 DEG C; besides, the specific gravity of the metal sodium is 0.97 g/cm<3>, so that the weight of the valve is reduced, the mass of the valve is lowered, movement physical quantity correlated with the mass of the valve is reduced correspondingly, and the work performance of the valve is better; furthermore, the valve disclosed by the invention is strong in rigidity and hardly bent.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of hollow is filled the valve of sodium, belongs to the technical field of gas car Component.
Background technique
Along with the development of internal-combustion engine to adjustment high load direction, the operating temperature of valve is more and more main high, and the operating temperature of exhaust valve has been up to the 850-900 degree, and traditional valve can not satisfy the requirement of internal-combustion engine.In order to solve the problems of the technologies described above, recently, when producing valve, can bear higher temperature in order to make valve, dish portion and local bar at valve have adopted austenite material, the conical surface built-up welding cobalt-based close prosperous, thereby the resistance to high temperature of valve, oxidation resistance and decay resistance all are enhanced, but the valve of this structure is when high temperature, all by valve seat insert transmission heat radiation, therefore, the heat dispersion of valve is relatively poor.
Summary of the invention
Technical problem to be solved by this invention provide a kind of perfect heat-dissipating, corrosion-resistant, volume is little and lightweight hollow sodium filling valve.
In order to solve the problems of the technologies described above, a kind of novel hollow sodium filling valve of the present invention, by dish portion, shaft and plug are formed, wherein, have in the described shaft along axial hollow space, described hollow space is filled with the sodium metal material, owing to have along axial hollow space in the shaft, hollow space is filled with the sodium metal material, and the fusing point of sodium metal is 97.81 ℃, when valve is worked, the very fast rising of temperature, sodium metal is by the solid-state liquid state that is converted into, and Liquid Sodium is constantly washed away valve retainer portion and shaft, and valve retainer portion and neck heat are passed rapidly, improved the heat dispersion of valve, by reducing the temperature about 100 ℃, in addition, the proportion of sodium metal is 0.97g/cm
3, therefore, having reduced the weight of valve, quality diminishes, and the motion physical quantity relevant with quality is also corresponding to be reduced, and makes the service behaviour of valve better; And rigidity of the present invention is strong, and is not flexible.
Above-mentioned a kind of novel hollow sodium filling valve, wherein, described sodium metal accounts for the 50%-60% of described hollow space volume, because sodium metal accounts for the 50%-60% of described hollow space volume, when sodium metal when being converted into liquid state, can make the easier current downflow that goes up of liquid metal sodium by solid-state, guarantee the flowability and the thermal conductivity of liquid metal sodium, thereby, further improved thermal diffusivity of the present invention.
The present invention can realize following beneficial effect:
1, has high thermal conductivity, can play the good heat transfer effect.
2, since the proportion of sodium less than 1, the weight of valve has had bigger alleviating.
When 3, temperature 500 was spent, the viscosity factor of sodium was little, was 1/4 under the normal temperature, and good fluidity makes the temperature conductivity of valve better.
4, the fusing point of sodium is 97.8 degree, boiling point are 883 degree, and the temperature range between fusing point and the boiling point differs more, and when valve was worked, sodium can not become gas, had guaranteed the heat dispersion of valve.
5, sodium at high temperature has compatibility preferably with alloying elements such as Fe, Nb, Cr, Ni, can not produce corrosion, the corrosion resistance and the working life of having guaranteed valve to the steel of valve.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of novel hollow sodium filling valve of the present invention, by dish portion 1, shaft 2 and plug 3 are formed, have along axial hollow space 4 in the described shaft 2, described hollow space 4 is filled with the sodium metal material, and the quantity of sodium metal material is unrestricted, in the present embodiment, in order to improve the thermal diffusivity of valve, sodium metal accounts for the 50%-60% of hollow space 4 volumes because sodium metal accounts for the 50%-60% of described hollow space volume, when sodium metal by solid-state when being converted into liquid state, can make the easier current downflow that goes up of liquid metal sodium, guarantee the flowability and the thermal conductivity of liquid metal sodium, thereby, thermal diffusivity of the present invention further improved.
Add man-hour, sodium metal is squeezed into strip according to the diameter of shaft, cut off according to the length of hollow space, with the sodium metal feeding hollow space that cuts off, valve carries out friction welding with plug 3 after charging into sodium, and shaft is sealed by mechanism hand, towards overlap, get final product under the postwelding red heat state.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating purpose of the present invention, and be not as limitation of the invention, as long as in essential scope of the present invention, all will drop in the scope of claim of the present invention the above embodiment's variation, modification.
Claims (2)
1. a novel hollow sodium filling valve is made up of dish portion, shaft and plug, it is characterized in that, has in the described shaft along axial hollow space, and described hollow space is filled with the sodium metal material.
2. a kind of according to claim 1 novel hollow sodium filling valve is characterized in that described sodium metal accounts for the 50%-60% of described hollow space volume.
