Further, the magnitude of interference of interference fit is 0.013～0.037.
Further, the diameter of inner chamber is 8.2.
Also provide a kind of according to a further aspect in the invention, irritated the sodium method, utilized above-mentioned filling sodium device, may further comprise the steps:
1) get the sodium sheet and remove porosity and the scale on surface after, be kept at and obtain clean sodium sheet in the anhydrous gasoline;
2) clean sodium sheet is pressed into the sodium silk, is kept in the anhydrous gasoline;
3) get the valve of irritating in the sodium device and carry out preheating step;
4) with a sodium silk wipe away clean after, left standstill one minute after inserting the valve inner chamber of preheating, the good valve of sodium has been irritated in the aperture of blocking valve with plug then;
5) will irritate the good valve of sodium and carry out incubation step, be cooled to room temperature then;
6) cooled valve is carried out the seam sealing.
Further, the sodium silk is diameter 4mm, length 100mm, and weight is the cylindrical body of 1.07～1.36 grams.
Further, the preheating step in the step 3) is 380～400 ℃ of insulation 30min for valve being placed temperature.
Further, incubation step is 380～400 ℃ of insulation 10min for the valve that will irritate sodium in temperature in the step 5).
The present invention has following beneficial effect:
A kind of filling sodium device provided by the invention makes filling sodium method more easy to implement, and the plug and the valve inner chamber of irritating simultaneously in the sodium device pass through interference fit, make the sealing of valve stronger.
A kind of filling sodium method provided by the invention is kept at the sodium silk in the anhydrous gasoline, make the sodium silk be not easy oxidation, has guaranteed to irritate the purity of sodium silk behind the sodium; Simultaneously, valve is carried out preheating step, anti-air-stop gate inner chamber produces pressure, has solved the not strong problem of valve sealing property.
Except top described purpose, feature and advantage, the present invention also has other purpose, feature and advantage.To do further detailed explanation to the present invention with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the filling sodium device of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, the invention provides a kind of filling sodium device, comprise plug 1, supporting 4, valve 3; Valve 3 is installed in the supporting 4; Be provided with valve inner chamber 5 in the valve 3, plug 1 is arranged in the valve inner chamber 5 through interference fit, and plug 1 is connected through seam with the surface of contact of valve inner chamber 5.Because the ambient temperature of valve 3 in engine operation reaches more than 200 ℃, and the motion repeatedly that does not stop, not in place in order to prevent plug 1 pressure, cause valve sealing incomplete, the present invention adopts interference fit with plug 1 and valve inner chamber 5.After plug 1 passed through interference fit with valve inner chamber 5, when magnitude of interference was 0.013～0.037, plug 1 cooperated closely with valve inner chamber 5, and good seal has solved plug and pressed problem not in place.When the diameter of valve inner chamber 5 was 8.2, the sodium silk can be packed in the valve inner chamber smoothly.
The present invention also provides a kind of method of utilizing above-mentioned device to irritate sodium, may further comprise the steps:
1) get the sodium sheet and remove porosity and the scale on surface after, be kept at and obtain clean sodium sheet in the anhydrous gasoline;
2) clean sodium sheet is pressed into the sodium silk, is kept in the anhydrous gasoline;
3) get the valve 3 of irritating in the sodium device and carry out preheating step;
4) with a sodium silk wipe away clean after, left standstill one minute after inserting the valve inner chamber 5 of preheating, the good valve of sodium 3 has been irritated in the aperture of blocking valve 3 with plug 1 then;
5) will irritate the good valve of sodium 3 and carry out incubation step, be cooled to room temperature then;
6) cooled valve 3 is carried out the seam sealing.
Because long-time the contact with air of sodium metal is easy to generate surface oxidising; For the oxidation reaction that prevents the sodium metal surface takes place; The present invention is left sodium metal in the anhydrous gasoline in; Prevent the oxidation of sodium metal, any chemical reaction does not take place in anhydrous gasoline and sodium metal simultaneously, avoids the volatilization or the corrosion of sodium metal.
When combined interference plug 1, earlier valve 3 is carried out preheating, the magnitude of interference that reduces plug 1 and valve inner chamber 5 is until being Spielpassung; Simultaneously because valve 3 is carried out The pre-heat treatment, can prevent since valve inner chamber 5 for after blind hole causes plug 1 and valve inner chamber 5 interference fit, valve inner chamber 5 produces outside air pressure, causes plug 1 and the incomplete problem of valve inner chamber 5 cooperations.
Carry out heat tracing with irritating the good valve of sodium 1, and cooling at room temperature, can make sodium metal by liquid transformation to solid-state, and release heat finally makes valve inner chamber 5 and extraneous air pressure maintain an equal level, anti-air-stop gate inner chamber 5 overpressure, influence filling sodium effect.
It is 4mm that the present invention is pressed into diameter with the sodium sheet, and length is 100mm, and weight is the cylindrical body sodium silk of 1.07～1.36g, has guaranteed the filling sodium content, simultaneously the sodium silk is better poured in the valve 3, and the sodium silk is stained with in anti-air-stop gate 3 apertures, and the sodium effect is irritated in influence.
Preheating step is 380～400 ℃ of insulation 30min for valve 3 being placed temperature.Because valve inner chamber 5 is blind holes; If valve 3 is not carried out preheating, directly plug 1 is pressed in the valve inner chamber 5, the gas in the valve inner chamber 5 produces the active force on outer top; Cause being difficult to plug 1 is pressed into fully the aperture of valve 3; In order to prevent the generation of above-mentioned phenomenon, the present invention carries out preheating with valve 3, and keeps the temperature of valve 3 when irritating sodium to remain in 300-350 ℃ the scope.
Incubation step makes the fully dissolving in valve 1 of sodium silk for the valve 3 that will irritate sodium is 380～400 ℃ of insulation 10min in temperature.
