The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is carried out concrete introduction.
Fig. 1 is the side sectional view of one embodiment of the invention; Fig. 2 is the top view of one embodiment of the invention.
As depicted in figs. 1 and 2: the constant-temperature high-pressure water-bath, comprise housing 10, pot cover 11, water tank 1, kerve 12, ball-cock assembly level control switch for water 2, pressure limiting valve 6, steam vent 7, heater 8, baffle plate 3, specific gravity bottle fixture 5 and outlet pipe 9, in the present embodiment, described specific gravity bottle fixture 5 is stone, certainly it also can be for the specific gravity bottle fixed cover etc., described pot cover 11 is arranged on the top of housing 10, form the enclosure space of water-bath with housing 10, described water tank 1 and kerve 12 are positioned at described enclosure space, be communicated with by ball-cock assembly level control switch for water 2, and the height of water tank 1 is higher than the height of kerve 12, the liquid level that is higher than kerve 12 with the liquid level that guarantees water tank 1, described heater 8 is arranged at the bottom of kerve 12, be used for the water level in the kerve 12 is heated, also be provided with baffle plate 3 in the described kerve 12, be used for placing specific gravity bottle 4 and specific gravity bottle fixture 5 etc., described specific gravity bottle fixture 5 is used for fixedly specific gravity bottle 4, prevent that it is in liquid medium dip or the overturning of kerve 12, bottleneck height during height is set guarantees that the highest liquid levels in the kerve 12 are lower than specific gravity bottle 4 and are positioned on the baffle plate 3 of baffle plate 3, outlet pipe 9 then is communicated with the bottom of kerve 12, pass simultaneously housing 10 and lead to the outside, in addition, described pressure limiting, valve 6 and steam vent 7 all are arranged on the pot cover 11, are used for the air pressure size in the control enclosure space.
The present invention puts into the constant-temperature high-pressure water-bath to specific gravity bottle 4 in use, by the liquid level in the ball-cock assembly water level switch 2 control water-baths, automatically adds the water in the water tank 1, can improve air pressure and the water temperature of water-bath inside by pressure limiting valve 6.When pressure limiting valve 6 was sealed air pressure jack-up in the space and comes, water under high pressure bath air pressure inside size then satisfied: P * S+mg=P' * S, and the water temperature boiling point of water namely is relevant with atmospheric pressure, generally is no more than 120 ℃.Wherein, P is outside atmosphere pressure, and S is the cross-sectional area of pressure limiting valve 6, and m is the quality of pressure limiting valve 6, and g is 9.807665m/s*s, and P' is the atmospheric pressure in the water-bath.
Concrete real density detection method is:
With the specific gravity bottle 4 of 25ml, clean, dry with distilled water first, be the quality m of the balance weighing specific gravity bottle of ten thousand/gram with sensibility reciprocal
1Get the sample of having dried and put into specific gravity bottle 4, the sample charge weight is about 1/3 of volume, and quality control of the experiment weighs up the quality m of specific gravity bottle 4 and sample at 4.5-5.0g
2To specific gravity bottle 4 interior injection distilled water, reach 2/3 of volume, place in the present invention, in hot bath, boil, remove the bubble that adheres on the sample.Before boiling, water tank 1 middle water level will expire, boiling time 1 hour.After leaving standstill cooling, distilled water is filled with to the proportion bottleneck again, bottle stopper makes the capillary of water from bottle stopper and overflows beyond the Great Wall, just illustrates and has filled water in the specific gravity bottle 4, dries the moisture outside the specific gravity bottle 4, claims that the quality of specific gravity bottle 4, sample and water is m
3From specific gravity bottle 4, pour out water and sample, fill distilled water after cleaning, claim the quality m of specific gravity bottle 4 and water
