Abstract
The utility model discloses a novel check valve, which is characterized by comprising a valve cylinder, wherein the valve cylinder is provided with a first valve cavity and a second valve cavity; the first valve cavity is communicated with the second valve cavity; a hollow column is arranged in the first valve cavity and is provided with a tube cavity; a round ball is arranged in the second valve cavity; the diameter of the round ball is bigger than the diameter of the tube cavity; the bottom end of the second valve cavity is provided with a base; the base is provided with a dispersing hole; the position of the dispersing hole corresponds to the position of the second valve cavity; two ends of the valve cylinder are respectively provided with a top plug and a bottom plug; the top plug is provided with a first through hole; the bottom plug is provided with a second through hole; and the first through hole, the tube cavity, the first valve cavity, the second valve cavity, the dispersing hole and the second through hole are successively communicated. The novel check valve disclosed by the utility model has a simple structure, is easy to manufacture and is convenient to use. According to the novel check valve, solution with low boiling point can be prevented from only flowing along one direction, the phenomenon that solution with high boiling point is polluted by backflow can be avoided, and thus the novel check valve is especially suitable for producing polypeptide and other chemical products.
Description
Technical field
The utility model relates to a kind of novel one-way valve.
Background technique
Rotary evaporator can rotate under heated at constant temperature, condition of negative pressure and form film, high-efficiency evaporating, and then condensation recovery solvent, be particularly suitable in the operations such as thermo-responsive material, crystallization, separation, solvent recovery, be the important instrument equipment of biology, medicine, chemical industry, food service industry research and production.Sample after condensation tube on the rotary evaporator is handled, low boiling separates with high boiling solution, in the low boiling solution input collection bottle.During actual the use, after lower boiling solution enters collection bottle since between condenser and collection bottle without any protective equipment, cause entering low boiling sample in the collection bottle and might flow backwards and pollute high boiling sample, cause manufacturing efficiency to reduce, cost of production increases.
The model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of and prevent that the refluence of the low boiling solution in the collection bottle from entering the novel one-way valve of condenser.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Novel one-way valve is characterized in that, comprises valve cylinder, and valve cylinder is provided with first valve pocket and second valve pocket; First valve pocket is communicated with second valve pocket; Be provided with open tubular column in first valve pocket, open tubular column is provided with tube chamber; Be provided with ball in second valve pocket, the ball diameter is greater than lumen diameter; The second valve pocket bottom is provided with base, and base is provided with dispersion hole, and dispersion hole is corresponding with the second valve pocket position; The valve cylinder two ends are respectively arranged with top plug and bottom plug; The top plug is provided with first through hole; Bottom plug is provided with second through hole; First through hole, tube chamber, first valve pocket, second valve pocket, dispersion hole and second through hole are communicated with successively.
Preferably, described open tubular column is cylindrical, and the first valve pocket shape is identical with the open tubular column shape.
Novel one-way valve in the utility model, simple in structure, easy to manufacture, easy to use.The utility model can limit low boiling solution only along one-way flow, can avoid flowing backwards and pollute higher boiling solution, especially is fit to the production of polypeptide and other chemical product.
Description of drawings
Fig. 1 splits schematic representation for the utility model structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, novel one-way valve comprises valve cylinder 1, and valve cylinder 1 is provided with first valve pocket 11 and second valve pocket 12; First valve pocket 11 is communicated with second valve pocket 12.First valve pocket 11 and second valve pocket 12 are cylindrical.First valve pocket, 11 diameters are greater than second valve pocket, 12 diameters.
Open tubular column 2 is cylindrical.Open tubular column 2 is provided with tube chamber 21.Open tubular column 2 is arranged in first valve pocket 11.First valve pocket, 11 shapes are identical with open tubular column 2 shapes.Because first valve pocket, 11 diameters are greater than second valve pocket, 12 diameters, therefore, open tubular column 2 is limited in first valve pocket 11.
Be provided with ball 3 in second valve pocket 12, ball 3 diameters are greater than the diameter of tube chamber 21.Second valve pocket, 12 bottoms are provided with base 4, and base 4 is provided with three dispersion hole 41, and dispersion hole 41 is corresponding with second valve pocket, 12 positions.Dispersion hole 41 numbers are three, can make the liquid through second valve pocket 12 disperse to flow out through dispersion hole 41.Valve cylinder 1 two ends are respectively arranged with top plug 5 and bottom plug 6.Top plug 5 is provided with first through hole 51.Bottom plug 6 is provided with second through hole 61.First through hole 51, tube chamber 21, first valve pocket 11, second valve pocket 12, dispersion hole 41 and second through hole 61 are communicated with successively.
During use, novel one-way valve is installed between condenser and the collection bottle; Sample after condenser is handled, low boiling solution enters in the collection bottle through first through hole 51, tube chamber 21, first valve pocket 11, second valve pocket 12, dispersion hole 41 and second through hole 61 successively.Flow backwards as the solution in the collection bottle, block tube chamber 21, therefore can avoid flowing backwards thereby then ball 3 can be rushed at open tubular column 2.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
