Abstract

The utility model discloses a multifunctional real density bottle, which can measure the real density or the apparent specific gravity of the liquid and the solid under each temperature. The multifunctional real density bottle is composed of a conical glass bottle with a vertex angle which is greater than 60 DEG, and a gas sucking piston system composed of a bottle neck and a bottle stopper. Through making use that at the time of high negative pressure, after the medium and the powder are heated and agitated, the escaping speed and the complete draining rate of the gas can be improved. Accordingly, the operation is compact; the measuring accuracy is improved; the suitable temperature range is wide; the measured materials are more; the devices are less, and the cost is low.

Description

Multifunctional real density bottle

The utility model relates to a kind of instrument of surveying liquid, solid real density or solid apparent gravity.

The T133 of known GB208 and AASHTO provides with Li Shi pycnometer survey powder real density method, institute and reaches only 0.01 gram/cubic centimetre of precision.GB5071 and ISO5018 provide with Ji Shi pycnometer and vacuum extractor and survey powder real density method, and precision increases, but can fail because of medium rises to overflow when in the operation temperature rise being arranged, and suitable warm territory is narrow.

The utility model aims to provide the multi-functional true density bottle that can accurately measure liquid, solid real density or apparent gravity, is suitable for wide temperature range, excessive, the simple to operation easy popularization of can not rising.

This instrument principal character is to constitute bleed piston system greater than the bottleneck of the circular cone vial of 60 degree and core tube, the kapillary of glass bottle stopper with sealing cap with drift angle, make the interior negative pressure that keeps of bottle to accelerate exhaust velocity by carrying the core tube of bleeding on the core tube fixator chucking, improve exhanstion rate and mensuration precision.

This instrument benefit is based on the pyriform bottle of conical flask floorage much larger than Li Shi or Ji Shi pycnometer, make the bisque attenuate and reduce gas effusion resistance, and because the piston system of bleeding had both made maintenance high negative pressure in the bottle, medium leakproof when guaranteeing temperature rise again, provide utilization thus and can heat the possibility of magnetic stirring apparatus the powder heated and stirred in the medium, the synergy of above factor improves gas effusion speed and exhanstion rate greatly, makes simple to operation, precision be better than 0.001 gram/cubic centimetre.

Below describe this instrument in detail with drawings and Examples.

Fig. 1 is the instrument sectional view, the bottleneck inboard of body 1 is a correct grinding garden cylinder, play the piston in cylinder wall effect, its top flange upper surface is finish-ground to the plane perpendicular to casing wall, guarantee that a bottle cavity volume becomes constant to measure precision to improve at the seam of bottle stopper 2 during with the driving fit of this plane, the bottom of bottle stopper 2 is core tubes of the spacious end, its length is more than two times of bottleneck cylinder face length, the outside is the correct grinding face of cylinder with bottleneck medial surface precision-fit, work the piston boit effect of bleeding, it can be twitched flexibly in casing wall and not have gas-liquid and leak.Gas that palpus is discharged in the bottle or liquid are discharged through the kapillary at core tube inner chamber and bottle stopper top, are connect by seam in the middle of core tube and the kapillary, and the seam external diameter is slightly larger than the bottleneck flange, are convenient to point to hold to hold pump its center hairiness pore up/down perforation.The kapillary upper end closely cooperates with sealing cap 3, can not need ground during with elastic-plastic material with taper or cylindrical ground when sealing cap is used glass.Fig. 2 works in heated and stirred process synoptic diagram for this instrument, body 1 places and can heat on the magnetic stirring apparatus 5, the liquid medium 8 that powder 7 to be measured and auxiliary measuring are arranged in the bottle, the bottle splash bar 6 that is magnetic at the end, produce negative pressure in the bottle for making, bottle stopper 2 is pressed down make seam and flange driving fit shown in the Zuo Bantu of Fig. 2 taking out sealing cap 3 back, cover tight sealing cap then, carry the core tube and use 4 tightenings of core tube fixator shown in half figure of Fig. 2 right side on firmly.Start heating stirrer, treat that the adsorbed gas of powder drains after, remove coring tube fixator and sealing cap, depress the core tube, promptly finish bleeding.When not considering heated and stirred, the bottle end, can make little convex as Fig. 1, otherwise get Fig. 2.Body volume and bottleneck diameter are designed to plurality of specifications by determination object.Other operations are carried out by corresponding standard.
