It is experimental facilities indispensable in laboratory.
But the liquid of any property cannot be immersed in the pump housing of vacuum diaphragm pump, experiment accident is otherwise will result in, is led
Cause destruction and the property loss of experimental data.The vacuum diaphragm pump of especially small-sized low noise, since its air inlet/outlet is frequent
Unlatching, so the liquid of any property can not be immersed in the pump housing.Due to the limitation of existing experimental facilities, in the process of experiment
In, it is necessary to experimenter keeps the vigilant of height at any time, will in advance be shut down to vacuum diaphragm pump once noting abnormalities,
Otherwise, will be because of the negative pressure being still had in system, and liquid is made to be immersed in vacuum diaphragm pump, it causes damages to experiment,
There are labor intensity it is big, working efficiency is low, experimental measurements are poor the problems such as.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of with design is scientific and reasonable, conveniently
Operation, the labor intensity for reducing experimenter, the laboratory improving conventional efficient, reduce loss, ensureing experimental data accuracy
With the bottle that shuts off.
The utility model solves its technical problem and following technical scheme is taken to realize：
A kind of use for laboratory shuts off bottle, it is characterised in that：By vial, bottle cap, mistake tracheae, mistake liquid pipe, intercepting sewer and float
Drift is constituted, and bottle cap is equipped in the vial bottle mouth position screw thread, and one is horizontally installed on the bottle cap and crosses tracheae, this crosses gas
Bottle cap is stretched out at the both ends of pipe, and one end forms air inlet, and the other end forms gas outlet, the lower part setting for crossing tracheae there are two with
The socket of its vertical unicom was equipped with liquid pipe in the spigot for closing on air inlet, was equipped in the spigot for closing on gas outlet
Intercepting sewer, the mistake liquid pipe and intercepting sewer are deep into the inside of vial, and the length of intercepting sewer was longer than the length of liquid pipe
The upper end opening of degree, the intercepting sewer is a conical opening, and a circle air passing hole is evenly equipped on the upper end tube wall of intercepting sewer, is being shut off
It is provided with a circle boss on the lower end inner wall of pipe, the buoy limited by boss is provided in intercepting sewer, the top of the buoy is
Pyramidal structure compatible with conical opening.
Moreover, the vial is high-boron-silicon glass bottle.
Moreover, the bottle cap is PP materials.
Moreover, the buoy is the hollow glass buoy made of high borosilicate.
The advantages of the utility model and good effect are：
A bottle 1. use for laboratory shuts off is closed the opening of intercepting sewer upper end using the principle of buoyancy, to prevent gas
Flowing, prevent liquid from immersing.In use, the air inlet of the bottle that shuts off is connected by pipeline with the container for holding analytical solution
It connects, gas outlet is connect by pipeline with vacuum diaphragm pump, once being pumped into liquid during filtering, buoy will be held up by liquid
To the position of conical opening, vacuum diaphragm pump works on, and negative pressure makes buoy be in close contact with conical opening, makees to play sealing
With, then prevent liquid from overflow intrusion vacuum diaphragm pump in.Since the liquid being pumped into being shut off in glass during suction filtration
It will not be immersed in vacuum diaphragm pump in product, to protect vacuum diaphragm pump without damage, prolong the service life, improve work effect
Rate reduces experimental cost, ensures the accuracy of experimental data.
2. the utility model scientific structure design is reasonable, has and be conveniently operated, reduce the labor intensity of experimenter, improve
Conventional efficient reduces loss, ensures the advantages of experimental data accuracy, is that a kind of use for laboratory with higher innovation shuts off
Bottle.

Specific implementation mode
Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of use for laboratory shuts off bottle, and innovation is：By vial 10, bottle cap 3, cross tracheae 2, cross liquid pipe 11,
Intercepting sewer 8 and buoy 7 are constituted, and are equipped with bottle cap in the vial bottle mouth position screw thread, one is horizontally installed on the bottle cap
