Abstract
The utility model discloses a buret flows, aim at do not have the scale mark on solving current buret, and liquid can the part adsorb on the pipe wall, lead to unable accurate problem of adding specific volume liquid. This buret flows includes the body, be provided with the scale on the body, the both ends of body are provided with liquid import, liquid outlet respectively. The utility model discloses a brand -new structural design has effectively solved the unable accurate problem of adding of liquid, has better application effect. The utility model discloses think about ingenious, simple structure, convenient to use, low in production cost can be arranged in the ration of chemical field liquid to add, has better market perspective.
Description
Technical field
The present invention relates to chemical field, be specially a kind of flowtube.
Background technology
In chemical field, especially in experimentation, it usually needs carry out the interpolation of the liquid of designated volume.At present, burette is generally used to be added.But not scale mark on existing burette, meanwhile, liquid can partial adsorbates on tube wall, therefore cause the accurate interpolation that cannot be carried out liquid.
To this end, the application provides a kind of new device to solve the problems referred to above.
Summary of the invention
The goal of the invention of the present invention is: on existing burette without scale mark, and liquid can partial adsorbates on tube wall, the problem causing cannot accurately adding designated volume liquid, it is provided that a kind of flowtube.The present invention uses brand-new structure to design, and efficiently solves the problem that liquid cannot accurately add, and has and preferably applies effect.Present inventive concept is ingenious, simple in construction, easy to use, and production cost is low, it is possible to the quantitative interpolation of liquid in chemical field, has preferable market application foreground.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of flowtube, including body, described body is provided with scale, the two ends of described body are respectively arranged with liquid-inlet, liquid outlet, described liquid outlet is tapered, and described body is additionally provided with valve, and body can be sealed and stop ambient atmos to enter tubular body by described valve；
Also including the side pipe being connected with body, be arranged on the air bag of side pipe opening, the gas in described air bag connects with body through side pipe, and the junction of described side pipe and body is between valve and liquid outlet.
In the normal state, valve is in open mode to the present invention, and air bag is connected with tubular body by side pipe, and owing to the air pressure inside and outside body is consistent, therefore air bag keeps fixing shape and volume.Liquid outlet is contacted with liquid, and blows up a balloon in liquid-inlet setting, draw liquid in body by blowing up a balloon.After liquid enters body, closing valve, under the effect of ambient pressure, liquid rests in body.Now, the gas volume in body is certain, and air bag is in a state of nature.By slight squeeze air bag, being slowly added of liquid can be realized.By the scale on body, the addition of recognizable liquid.By controlling the extruding degree of air bag, the interpolation of designated volume liquid can be realized.The present invention is reasonable in design, simple in construction, it is possible to realize the interpolation of designated volume liquid, has preferable effect.
As preferably, described side pipe is L-shaped.Using this structure, it is possible to prevent liquid entry in side pipe, when effectively preventing air sac pressing, liquid suck-back enters in side pipe simultaneously.
Described body, side pipe are respectively adopted glass material and make.
Described air bag uses elastomeric material to be prepared from.
Described air bag uses rubber to be prepared from.
As preferably, described side pipe, air bag are respectively two groups, and described side pipe is symmetricly set on body.Use this this structure, it is possible to by control two air bags, it is achieved in body fluid quick, accurately drip.
As preferably, use one-body molded between described side pipe and body.Use which, there is between body and side pipe preferable sealing effectiveness, and can one-shot forming.
In sum, the present invention provides a kind of brand-new flowtube, and it has simple in construction, easy to use, advantage reasonable in design, it is possible to realizes the accurate interpolation of designated volume liquid, has preferable effect.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the structural representation of inventive flow pipe.
Labelling in figure: 1 is body, 2 is liquid outlet, and 3 is liquid-inlet, and 4 is side pipe, and 5 is air bag, and 6 is valve.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
Any feature disclosed in this specification, unless specifically stated otherwise, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, an example during each feature is a series of equivalence or similar characteristics.
Embodiment 1
As shown in the figure, the flowtube of the present embodiment includes body, the side pipe being connected with body, is arranged on the air bag of side pipe opening, the two ends of body are respectively arranged with liquid-inlet, liquid outlet, liquid outlet is tapered, valve it is additionally provided with on body, body can be sealed and stop ambient atmos to enter tubular body by valve, uses one-body molded between side pipe and body.
In the present embodiment, side pipe is L-shaped, and the gas in air bag connects with body through side pipe.Body, side pipe are respectively adopted glass material and make, and air bag uses rubber to be prepared from.
As preferably, side pipe, air bag are respectively two groups, and side pipe is symmetricly set on body.
In the normal state, valve is in open mode to the present invention, and air bag is connected with tubular body by side pipe, and owing to the air pressure inside and outside body is consistent, therefore air bag keeps fixing shape and volume.Liquid outlet is contacted with liquid, and blows up a balloon in liquid-inlet setting, draw liquid in body by blowing up a balloon.After liquid enters body, closing valve, under the effect of ambient pressure, liquid rests in body.Now, slight squeeze air bag, make the liquid levels in flowtube concordant with graduation mark, simultaneously the gas of delivery flow pipe pipe end；Now, liquid-inlet alignment is needed the container added, continues extruding gasbag, it is achieved the interpolation of designated volume liquid.
The invention is not limited in aforesaid detailed description of the invention.The present invention expands to any new feature disclosed in this manual or any new combination, and the arbitrary new method that discloses or the step of process or any new combination.
