Description
Technical field
The present invention relates to a kind of automatic vent automatic liquid-stopping device.
Technical background
Automatic vent automatic liquid-stopping device is that a kind of application is installed very widely, as is applied to medical instruments field and realizes the automatic vent of transfusion device, liquid function only, facilitates clinical administration; Being applied to chemical industry field, is that an a little assurance reaction system enters without gas and needs continuously or the system of regularly adding liquid reactants is given security.
The automatic vent automatic liquid-stopping device using at present, mostly liquid parts are only arranged on to the liquid outlet place of device lowermost end, only liquid parts can be buoy accessory or membrane material, this automatic vent automatic liquid-stopping application of installation can produce following problem in transfusion device: 1) when only liquid parts are buoy accessory or membrane material, after liquid parts only only play liquid function, liquid level in device can rest on the joint that stops liquid parts and liquid outlet, cause the interior liquid level position of device too low, in follow-up liquid infusion process, need through special operational again by device in liquid level raise, complex operation, 2), when only liquid parts are buoy accessory, to be only subject to the impact of liquid component and degree of purity larger for liquid function, slightly impurity, granule, and buoy accessory just cannot coincide with liquid outlet, thus forfeiture automatic liquid-stopping function, 3) when only liquid parts are buoy accessory, to the adaptation of buoy accessory and liquid outlet joint, require very high, thereby require very harsh to the production and processing mode of above two accessories, as the control of the precision of mould, raw-material selection, process of manufacture etc. all needs a large amount of checkings and control, careless slightly this device that will directly cause is lost automatic liquid-stopping function.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, and aerofluxus, only liquid is reliable for effect, and processing technique is simple, easy to operate automatic vent automatic liquid-stopping device.
Technical scheme of the present invention is, a kind of automatic vent automatic liquid-stopping device, comprise top cover and housing, housing is divided into inner chamber and exocoel two parts, the top of internal chamber wall and the top of outer chamber wall are all connected with top cover, inner cavity top cover is provided with steam vent and inlet, and the inner chamber liquid outlet top of inner chamber bottom is provided with only liquid filter membrane; Exocoel portion top cover is provided with air inlet that can folding, and the exocoel liquid outlet of exocoel bottom is provided with automatic exhaust device.
Described automatic exhaust device is comprised of gas-liquid separation pipe and protective cover; the top of gas-liquid separation pipe is stretched in exocoel; the inwall of bottom and exocoel liquid outlet is adhesively fixed; lower end is stretched out exocoel and is connected with conduit; protective cover is arranged on the top of gas-liquid separation pipe; and between gas-liquid separation pipe, have gap, protective cover is relative with inner chamber liquid outlet.
Described protective cover is umbrella or plane.
In described gas-liquid separation pipe, be provided with one or more gas-liquid separation groove.
Described only liquid filter membrane is fixed on the brace table of inner chamber bottom by ultrasonic welding process or heat seal process or mechanical process for pressing.
On described steam vent, be provided with exhaust gas filter film, exhaust gas filter film is hydrophobic air filter membrane, on ultrasonic welding process or heat seal process or mechanical process for pressing fixed roof.
Inlet air filtration film is set on described air inlet, and inlet air filtration film is hydrophobic air filter membrane, and inlet air filtration film is by ultrasonic welding process or heat seal process or mechanical process for pressing fixed roof.Air inlet is outside equipped with gland, can open, seal air inlet.
On described top cover, be provided with adding set.
Automatic vent automatic liquid-stopping apparatus structure of the present invention is simple, reliable for effect, easy to use.In preferred embodiment; in the incipient stage; liquid flows into inner chamber by the inlet of device; liquid complete wetting flows into exocoel after stopping liquid filter membrane and being full of inner chamber; from inner chamber dripping, first drop in protective cover; protective cover has reduced the potential energy of drop, makes drop finally can only slowly fall into exocoel along the peripheral clearance of protective cover.The liquid level that flows into exocoel can raise gradually, and because gas-liquid separation pipe is distributed with gas-liquid separation groove vertically, because its capillary effect, without external force in the situation that, can only be passed through air, liquid cannot enter.When liquid falls from protective cover, in the surrounding of gas-liquid separation pipe, form gradually the liquid level of certain altitude, along with the rising of liquid level, the air in exocoel is also concentrated automatically and is discharged from the gas-liquid separation groove of gas-liquid separation pipe.When liquid level is elevated to pressure that liquid produces and is greater than the surface tension of gas-liquid separation groove, liquid starts to enter from gas-liquid separation groove the inside of gas-liquid separation pipe, thereby enter in the conduit being connected with automatic vent automatic liquid-stopping device, because the liquid in exocoel is abundant, the liquid that now enters conduit is continuous.In whole feeding process, in conduit, there will not be the liquid of entrapped air, the operational approach without special, saves time.
When liquid completes infusion, after only liquid filter membrane automatic liquid-stopping in inner chamber, when changing infusion bottle and proceed infusion as needs, can this automatic vent automatic liquid-stopping device directly be inserted in new infusion bottle, at this moment the steam vent on inner chamber can arrive the Bas Discharged of the air in feed tube and inner chamber extraneous automatically, along with the discharge gradually of air, thereby newly change liquid in infusion bottle, also by continuing to flow into inner chamber, realize the continuous transfusion function after automatic liquid-stopping.
After whole feeding processes complete, existence due to automatic liquid-stopping function, remain in automatic vent automatic liquid-stopping device and below liquid in conduit cannot continue infusion, now, open the air inlet in normally off, outside air enters into exocoel after can filtering by air inlet, and makes residual liquid continue infusion, guarantees that liquid makes full use of.
