Abstract
The utility model discloses a kind of fluid-tight bottle, it comprises liquid holding bottle, described liquid holding bottle top is provided with opening, in liquid holding bottle, be provided with blast pipe integrated with it, blast pipe one end is in liquid holding bottle, the other end runs through liquid holding bottle bottom, and one end that blast pipe is positioned at liquid holding bottle bends downwards to the extension of liquid holding bottle top and end, and the other end that blast pipe extends liquid holding bottle bottom is arranged with sealing-plug outward.The utility model adopts above structure, insert in reaction bulb the one end that exhaust shroud is provided with to sealing-plug, with sealing-plug, seal reaction bulb bottleneck, and the seal fluid height in liquid holding bottle is controlled between the exhaust outlet and the top of bending part of blast pipe in liquid holding bottle, just can play fluid-tight effect, avoid air to enter interference experiment in reaction bulb, also the gas in reaction bulb can be discharged.Liquid holding bottle of the present utility model and blast pipe are integrated, and air-tightness is good, are convenient to produce.
Description
Technical field
The utility model relates to a kind of chemical reaction instrument, relates in particular to a kind of fluid-tight bottle.
Background technology
In laboratory, often can carry out various chemical experiments, generally in reaction bulb, add after determinand and reaction reagent, need to liquid seal device be installed at reaction bulb bottleneck.While especially including the experiment of redox reaction of γ-ray emission, if liquid seal device is not installed, airborne oxygen can enter in reaction bulb, reduzate may be oxidized, and interference experiment data, affect experimental result.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, fluid-tight bottle that air-tightness is good.
For achieving the above object, the utility model is by the following technical solutions: fluid-tight bottle, it comprises liquid holding bottle, described liquid holding bottle top is provided with opening, in liquid holding bottle, be provided with blast pipe integrated with it, blast pipe one end is in liquid holding bottle, and the other end runs through liquid holding bottle bottom, one end that blast pipe is positioned at liquid holding bottle is extended to liquid holding bottle top and end bends downwards, and blast pipe extends outside one end of liquid holding bottle bottom and is arranged with sealing-plug.Adopt above structure, liquid holding bottle and blast pipe are one-body molded, simple in structure, easy to process, air-tightness is good, the sealing-plug connecting on the utility model blast pipe is arranged on reaction bulb bottleneck, can avoid air to enter interference experiment in reaction bulb, and the gas in simultaneous reactions bottle can be discharged by blast pipe.
Described liquid holding bottle and blast pipe are glass or plastic material.Under the prerequisite that can not react with plastics at seal fluid, use the liquid holding bottle of plastic material not only can reduce costs, and easy to process, spoilage is low.
When described blast pipe is plastic material, liquid holding bottle opening is extended in blast pipe one end, and wherein bending part is plural telescopic joint, thereby convenient by the bending of blast pipe one end.
Described sealing-plug is rounding bench-type.
Described sealing-plug is rubber stopper.
The utility model adopts above structure, insert in reaction bulb the one end that exhaust shroud is provided with to sealing-plug, with sealing-plug, seal reaction bulb bottleneck, and the seal fluid height in liquid holding bottle is controlled between the exhaust outlet and the top of bending part of blast pipe in liquid holding bottle, just can play fluid-tight effect, avoid air to enter interference experiment in reaction bulb, also the gas in reaction bulb can be discharged.Liquid holding bottle of the present utility model and blast pipe are one-body molded, and air-tightness is good, are convenient to produce.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the cutaway view that the utility model fluid-tight bottle coordinates with reaction bulb;
Fig. 2 is the structural representation of the utility model fluid-tight bottle.
The specific embodiment
As shown in Figure 1, the utility model fluid-tight bottle, it comprises liquid holding bottle 1, described liquid holding bottle 1 top is provided with opening, in liquid holding bottle 1, be provided with blast pipe 2 integrated with it, blast pipe 2 one end are in liquid holding bottle 1, and the other end runs through liquid holding bottle 1 bottom, one end that blast pipe 2 is positioned at liquid holding bottle 1 is extended to liquid holding bottle 1 top and end bends downwards, and blast pipe 2 extends outside one end of liquid holding bottle 1 bottom and is arranged with sealing-plug 3.
Described liquid holding bottle 1 and blast pipe 2 are glass or plastic material.
Described sealing-plug 3 is rounding bench-type.
Described sealing-plug 3 is rubber stopper.
The utility model adopts above structure, adds after determinand and reaction reagent in reaction bulb 4, and insert in reaction bulb 4 one end that blast pipe 2 is arranged with to sealing-plug 3, uses sealing-plug 3 by reaction bulb 4 bottle sealings.Then in liquid holding bottle 1, pack seal fluid into, the liquid level of seal fluid will be positioned at higher than blast pipe 2 exhaust outlet of liquid holding bottle, prevent that air from entering in reaction bulb 4 by the exhaust outlet of blast pipe 2, simultaneously, the liquid level of seal fluid will, lower than the top of bending part, prevent that seal fluid from entering in reaction bulb 4 through blast pipe 2 suck-backs.When the interior generation chemical reaction of reaction bulb 4, the gas of generation can discharge by blast pipe 2, can prevent that again air from entering interference experiment in reaction bulb 4.
As shown in Figure 2, the utility model also provides the exhaust pipe structure of another kind of embodiment: described blast pipe 2 is plastic material, and liquid holding bottle 1 opening is extended in blast pipe 2 one end, and the bending part of blast pipe 2 is plural telescopic joint 5.Bending by telescopic joint 5 is inserted blast pipe 2 one end in liquid holding bottle 1.During use, the liquid surface height controlling of seal fluid is at blast pipe 2 between the exhaust outlet in liquid holding bottle 1 and liquid holding bottle 1 opening.
