Abstract
A suck-back-preventing bubbler is composed of a glass buffering air guide pipe, a rubber seal ring and a standard port liquid storage pipe. The glass buffering air guide pipe is a long and thin glass pipe, a spherical buffering area is formed in the position nearby an air inlet, the long and thin glass pipe is used for air input, and the buffering area is used for preventing liquid placed in the bubbler from being sucked back. The rubber seal ring is a connection sleeve ring arranged between the glass buffering air guide pipe and the standard port liquid storage pipe.
Description
Technical field
The utility model relates to a kind of suck-back device, especially for a kind of anti-suck bubbler of aeration in chemical experiment.
Background technology
In chemical experiment aeration process, in order to observe the flow velocity that passes into gas or the purpose that reaches gas washing, often adopt bubbling device.Bubbling device commonly used is generally assembled by bottle,suction, rubber stopper, glass tube, rubber tube etc., can realize gas importing, bubbling, buffering (anti-suck), four functions of gas derivation on principle.But instrument connects complicated, during installation fee and take limited experimental bench space.
The utility model content
The purpose of this utility model is to provide a kind of anti-suck bubbler, to solve existing bubbling device complexity, during installation fee and take the problem in limited experimental bench space.
A kind of anti-suck bubbler cushions wireway, rubber seal, three assemblies of standard mouth liquid storage pipe by glass and forms, described glass buffering wireway is one the slender glass tube of a spherical buffering area to be arranged near air inlet, slender glass tube imports for gas, and buffering area is for preventing that bubbler from taking up the liquid suck-back; Described rubber seal be glass buffering wireway with standard mouth liquid storage pipe between be connected lasso.
As further preferred, standard mouth liquid storage pipe is the lower end closed glass tube of tool standard ground, its top is one section short glass tube, slightly larger in diameter is in the slender glass tube diameter of glass buffering wireway, glass buffering wireway just can be inserted wherein, its middle part is a standard ground, for making being connected between this bubbler and other standard mouth reaction kit or container, the glass tube that its underpart is an end opening sealing, diameter is greater than glass buffering wireway lower elongate diameter glass tube and is less than or equal to standard ground lower end diameter, there is an above circular hole at the ground place that is near the mark on the top of this glass tube, derivation for gas, there is a groove middle and lower part of this glass tube, take up the height reference of liquid for its inside.
Beneficial effect:
Design the small and exquisite bubbler of a kind of volume, can realize the functions such as gas importing that traditional complicated bubbling device has, bubbling, buffering (anti-suck), gas derivation; This bubbler adopts standard mouth simultaneously, and the assembling of convenience and other standard mouth glass reaction instrument or container, install simple and easy saving time, and saves space.
The accompanying drawing explanation
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Wherein: 1-glass buffering wireway, 2-rubber seal, 3-standard mouth liquid storage pipe.
The specific embodiment
As shown in Figure 1, anti-suck bubbler bag expands glass buffering wireway 1, rubber seal 2,3 three assemblies of standard mouth liquid storage pipe.Described glass buffering wireway is one the slender glass tube of a spherical buffering area to be arranged near air inlet, and slender glass tube imports for gas, and buffering area is for preventing that bubbler from taking up the liquid suck-back, rubber seal 2 are glass buffering wireways with standard mouth liquid storage pipe between be connected lasso, cushion being connected and sealing between wireway and standard mouth liquid storage pipe for glass, standard mouth liquid storage pipe is the lower end closed glass tube of tool standard ground, its top is one section short glass tube, slightly larger in diameter is in the slender glass tube diameter of glass buffering wireway, glass buffering wireway just can be inserted wherein, middle part is a standard ground, for make this bubbler can with other standard mouth reaction kit or container between be connected, the glass tube that its underpart is an end opening sealing, diameter is greater than glass buffering wireway lower elongate diameter glass tube and is less than or equal to standard ground lower end diameter, there is an above circular hole at the ground place that is near the mark on the top of this glass tube, derivation for gas, there is a groove middle and lower part of this glass tube, take up the height reference of liquid for its inside.
Three part assemblies of anti-suck bubbler are connected, and the lower outlet of glass buffering wireway 1 will be connected by rubber seal 2 with the top of standard mouth liquid storage pipe 3, leaves certain interval, facilitates the effusion of gas; Add required liquid from glass buffering wireway 1 suitable for reading, standard mouth liquid storage pipe 3 has scale, and liquid height reaches the groove position; The top air inlet of this bubbler is connected with the ingress pipe of gas, coats Seal Oil around bubbler standard ground, then bubbler is inserted to standard mouth reaction kit or the container that needs to import gas, can carry out aeration.
This embodiment just embodies the preferred special case of the utility model spirit, and those skilled in the art fully can be according to the purport of the utility model patent, and flexible, reached best implementation result in addition.The utility model is modified or is equal to replacement, and do not break away from the spirit and scope of the utility model patent, it all should be encompassed in the middle of the claim scope of the utility model patent.
