Embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
With reference to shown in Fig. 1 to Fig. 5, a kind of precision glass volumetric apparatus provided by the present invention, the present embodiment is with 1000ml Exemplified by the Glass capacity vessel of capacity, related size is also the Glass capacity vessel setting with 1000ml capacity, according to difference The Glass capacity vessel of amount of capacity, related size are also made to be adapted adjustment setting.Including main bottle body 1, main bottle body 1 includes bottom Seat 101 and main pipeline 102, the lower end of main pipeline 102 are connected with base 101, and main pipeline 102 is provided with graticule 2, graticule 2 Scale is 1000ml, and liquid volume scale when being 20 DEG C of normal temperature, above-mentioned is prior art part, is just repeated no more herein.With Unlike prior art, in addition to the first capillary 3, the outer diameter D of the first capillary 3 are arranged to 5mm, and internal diameter d is arranged to 3mm, the first capillary 3 include measuring section 301 and linkage section 302, and measuring section 301 is located at the side of main pipeline 102, and and main pipeline 102 are set in parallel, and the lower end of measuring section 301 is connected with base 101, the upper end of measuring section 301 and one end of linkage section 302 Be connected, the other end of linkage section 302 is connected with main pipeline 102, and with the shape of main pipeline 102 x1, angle x1 in an angle Angle be arranged to 50 °, measuring section 301 is provided with fine gauge 301a, and different class are indicated beside fine gauge 301a Temperature value (- 45 DEG C of 0-5-10- ...), and the scale of the constant volume liquid corresponding with each grade of temperature value, every 5 DEG C of temperature value For a rough segmentation degree, there is the subdivision degree of 5 deciles in a rough segmentation degree, be constant volume under real time temperature corresponding to fine gauge 301a The liquid level of liquid should where position, so as to the liquid needed for accurate constant volume.
Preferably, also including the second capillary 4, the second capillary 4 is consistent with the profile of the first capillary 3, and with first mao Tubule 3 is symmetrical set, and is connected at the opposite side of main pipeline 102, also shape between the upper end of the second capillary 4 and main pipeline X2 in an angle, angle x2 angle are also 50 °, internal between the second capillary 4 and main bottle body 1 not connect, and are primarily served The overall balanced action of the volumetric apparatus of the present invention, prevents volumetric apparatus from being tilted toward one side, can also work as handle and use.In addition, By between the central axis of the central axis of the first capillary 3, the central axis of the second capillary 4 and main pipeline 102 apart Distance b1, b2 is arranged to 40mm.
Preferably, being connected between the first described capillary 3, the second capillary 4 and main pipeline 102 by support 5, prop up Frame 5 prevents the first capillary 3 and the second capillary 4 to be broken to fix the first capillary 3 and the second capillary 4.
Preferably, the port inner wall of the described upper end of main pipeline 102 is frosted inwall, the height h of frosted inwall is 20mm, To be supported the use with ground glass stopper or plastic plug, prevent the liquid in volumetric apparatus from flowing out.
The volumetric apparatus of the present invention is to be significantly greater than main pipeline using liquid level change of the liquid in the first capillary 3 Liquid level changes in 102, so as to more accurately determine the volume of constant volume liquid under Current Temperatures.When environment temperature rises, The volume of liquid is because the principle expanded with heat and contract with cold, liquid volume expand, and the first capillary 3 is because its internal diameter d is thinner, fluid column Highly rise is obvious, according to the constant volume liquid volume under the clear and definite Current Temperatures of fine gauge 301a on the first capillary 3;Together Sample, when environment temperature declines, the fluid column in the first capillary 3 declines substantially, and according to the trickle quarter on the first capillary 3 The constant volume liquid volume spent under the clear and definite Current Temperatures of 301a.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention, And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above Change, modification will all fall in the range of claims of the present invention.
