It is unsmooth, it is possible to the case where gas nozzle above is bounced, is broken into pieces so as to cause liquid splash and gas nozzle.In addition, general tapping
Valve is all manually opened and closes, not only troublesome in this way, it is also possible to make to be stained with solution on hand.
Utility model content
The utility model proposes a kind of Jet-flow extraction devices, gas nozzle can be effectively prevent to bounce, moreover it is possible to put without being opened and closed manually
Liquid valve.
The technical solution of the utility model is achieved in that a kind of Jet-flow extraction device, including jet stream bottle, extraction flask, true
Sky pumps and control circuit, the double-deck fixed plate including bracket and thereon, and jet stream bottle and extraction flask, jet stream are arranged in the double-deck fixed plate
The top of extraction flask is arranged in bottle, and the extraction flask is container of the bottom in cone, and bottom is connected with bleeder valve, described to penetrate
The lower end of stream bottle is connected with an integrally formed tubule, and tubule extends in extraction flask bottom close to tapping valve position；It is described
The upper opening of jet stream bottle is simultaneously connected with matched gas nozzle, and gas nozzle is controlled to a vacuum pump by pipeline；On the gas nozzle also
The cap being fixed equipped with one, cap edge placement connect several buckle closures, and bracket is equipped with and the matched transverse slat of buckle closure.
Preferably, the jet stream bottle upper side, which is additionally provided with one, prevents the excessively high pressure relief opening for leading to rupture of air pressure, pressure release
Mouth is equipped with matched rubber stopper.
Preferably, the bleeder valve is solenoid valve, is connected and controlled by control circuit by route.
Compared with the prior art, the advantages of the utility model are: covered on gas nozzle plug with cap, and with buckle closure button
On, to prevent gas nozzle from popping up at work；When needing to release the liquid in extraction flask, electricity can be opened by control circuit
The bleeder valve of magnetic valve type, so that it may not have to opening and closing bleeder valve manually, improve working efficiency.
