Abstract

The utility model relates to an araeometer which enables the test container of a liquid absorption araeometer to communicate with atmosphere and do test under ordinary pressure. A siphon is arranged in the reached container. One end of the siphon is connected with a liquid absorption pipe, and the other end is provided with an opening above the bottom of the container. A small hole is arranged on a liquid absorption ball, and annular scales are arranged on the araeometer. When tests, normal pressure is needed, which can improve test accuracy. The siphon can prevent leakage. When the liquid absorption ball is extruded once, liquid automatically flow out and is emptied because of siphon action. The utility model has the advantages of simple structure, convenient operation, high safety, accurate testing result, good repeatability, and high efficiency.

Description

Siphon liquid araeometer

The utility model relates to a kind of imbibition type picnometer, especially the time can keep in the picnometer test container for normal atmosphere pressure and prevents the hydrocone type areometer that liquid leaks from pipette in test.

At present, the structure of known imbibition type picnometer is by adorning float-type specific gravity meter in the drum shape glass container, in the bottom of bucket installing pipette, forming at the upper unit Liquid absorption ball of bucket.After utilizing Liquid absorption ball to suck fluid to be measured in the bucket, picnometer is floated, and reads the fluid to be measured rate of specific gravity from its scale.General imbibition type picnometer is when test, ullage space is unsettled negative pressure state, the height of negative pressure value is sucked the proportion and the temperature effect of liquid measure, liquid, fluctuation can be controlled than disaster, influences measurement accuracy, in addition, the test container of above-mentioned imbibition type picnometer is equivalent to a funnel, leakage phenomenon easily takes place, contaminated environment or make and have the corrosive liquids drippage, very dangerous.

The purpose of this utility model provides a kind of siphon liquid picnometer, and it can make the measurement of proportion carry out under condition of normal pressure, and can prevent to leak, and improves test accuracy and is convenient to reading.

The purpose of this utility model is achieved in that in transparent tubbiness test container a U trap is set that this Guan Yiduan joins by container bottom and outer pipette; The other end is opening above container bottoms, in upper opening of container Liquid absorption ball is housed, air hole is arranged at the top at ball, and float-type specific gravity meter places container, during with hand extruding Liquid absorption ball, the ball internal volume reduces, with finger aperture on the ball is blocked, when making it recover original form, container promptly is negative pressure state again, liquid is inhaled into along U trap, and float-type specific gravity meter is floated.The annular color scale of printing on this picnometer can both be read rate of specific gravity from any angle.As long as liquid level is lower than U trap upper bend point, liquid just can not leak.When decontroling aperture, then container is communicated with atmosphere, becomes malleation (being normal pressure) by negative pressure in the container, the result who under this state, the tests influence that is not stressed, and its rate of specific gravity is accurately.Test finishes, and blocks aperture on the Liquid absorption ball with finger, gently presses Liquid absorption ball again, and then container inner pressure increases, and makes fluid to be measured through the U trap emptying of flowing automatically, and finishes test jobs.

Owing to adopt above-mentioned siphon scheme, stable atmospheric pressure state in the container avoids pressure surge to improve test accuracy when having realized test, uses U trap also can prevent to leak and the emptying of flowing automatically its simple structure, easy to use, accuracy of reading after test.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the utility model longitudinal diagram.

Fig. 2 is I-I cut-open view of Fig. 1.

Fig. 3 is float-type specific gravity meter figure.

In Fig. 1,1, the right section 8 of aperture 5, pipette 6, testing liquid 7, U trap, U trap left side section on the transparent test container 2 of tubbiness, U trap 3, Liquid absorption ball 4, Liquid absorption ball

9, float-type specific gravity meter 10, annular color scale.

As shown in Figure 1, in bulk containers (1), U trap (2) is set, its left pipeline section (8) is communicated with container bottom pipette (5), and container top suit Liquid absorption ball (3) has aperture (4) on ball, place float-type specific gravity meter (9) in container.During test liquid (6) is sucked in the container, it is empty that U trap (2) left side section (8) is inhaled, and liquid level requires to be lower than position (10).Can prevent that the liquid in the container from discharging along U trap automatically.Annular color scale (10) is arranged on the float-type specific gravity meter (9), and its contrast is big, and contrast is obvious, and interpretation easily can improve testing efficiency and accuracy from any angular readings.

Claims

1, a kind of imbibition type hydrocone type areometer is characterized in that being provided with in the test container (1) U trap (2), and this manages a termination pipette (5), and the other end is opened on container bottom top (7).

2, hydrocone type areometer according to claim 1 is characterized in that Liquid absorption ball (3) top has breeder tube (4).
