Abstract
The utility model discloses a conduit pipe of preventing suck-back, which is characterized in that a big bubble of preventing suck-back is arranged between the air inlet and the air outlet of the conduit pipe; the size of the bubble of preventing suck-back, the distance from the bubble of preventing suck-back to the air inlet and the distance from the bubble of preventing suck-back to the air outlet can be determined according to different requirements. When being used, the utility model can prevent the suck-back well without the help of other tools.
Description
Affiliated technical field:
The utility model relates to a kind of conduit, is a kind of suck-back-prevention type conduit.
Background technology:
See much of the bigger gas of some solubility in the laboratory and need absorb processing, may influence experiment effect, even damage instrument if produce the suck-back phenomenon.Present existing technology is to use the common conduit gas outlet to be placed on apart from the local of liquid level one segment distance or to add a funnel in the gas outlet of conduit and prevents suck-back.It is cumbersome to operate.
Summary of the invention:
In order to overcome and improve the deficiency of existing technology, the utility model provides a kind of conduit, and this kind conduit need can not prevent the suck-back phenomenon that produced preferably by other instrument when absorbing the bigger gas of solubility.
The technical scheme that its technical problem that solves the utility model adopts is:
Between the air inlet of common conduit and gas outlet, do the bigger anti-suck bubble of a volume, wherein the gas outlet do shorter.It is characterized in that between air inlet and gas outlet, having an anti-suck bubble that volume is bigger.Like this when the gas bigger to solubility absorbs, because the gas dissolving is too fast, cause that pressure diminishes in the wireway, liquid in containers is absorbed in the anti-suck bubble of conduit, thereby the liquid level that causes container drops to gas outlet bottom, stop suck-back, and also have gas absorbing liquid in the conduit this moment, gas can not overflowed yet.Can prevent effectively that so just liquid is gone into the phenomenon of generation container by suck-back to the big GAS ABSORPTION of solubility the time.
The beneficial effects of the utility model are: the suck-back phenomenon that is produced in the time of can under not by the situation of other instrument, preventing to absorb the big gas of solubility preferably, and also operation is simple.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Figure is a plan view of the present utility model.
The specific embodiment:
In the drawings: 1. air inlet, 2. anti-suck bubble, 3 gas outlets.
When conduit is made, between air inlet and gas outlet, do an anti-suck bubble, the size of anti-suck bubble, the anti-suck bubble is apart from the distance of air inlet, and the anti-suck bubble can be done according to different needs apart from the distance of gas outlet.In use, the air inlet bubble props up in vessel port, and the one section suitable distance in liquid level below is inserted in the gas outlet, just can well prevent suck-back like this when the gas big to solubility absorbs.
