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 a kind of application device widely, realizing the automatic vent of transfusion device, only liquid function, facilitating clinical administration as being applied to medical instruments field; Being applied to chemical industrial field, is that an a little guarantee reaction system enters without gas and needs system that is continuous or timing adding liquid reactant to give security.
The automatic vent automatic liquid-stopping device of current use, mostly only liquid parts are arranged on 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 be buoy accessory or membrane material time, play only after liquid function at only liquid parts, liquid level in device can rest on the joint of only liquid parts and liquid outlet, cause liquid level position in device too low, need again liquid level in device to be raised through special operational in subsequent liquid infusion process, complex operation, 2) when only liquid parts are buoy accessory, only liquid function is subject to the impact of liquid component and degree of purity comparatively greatly, slightly impurity, granule, and buoy accessory just cannot coincide with liquid outlet, thus loses automatic liquid-stopping function, 3) when only liquid parts are buoy accessory, require very high to the adaptation of buoy accessory and liquid outlet joint, thus require very harsh to the production and processing mode of above two accessories, control etc. as the precision of mould, raw-material selection, process of manufacture all needs a large amount of checkings and control, and careless slightly this device that will directly cause loses automatic liquid-stopping function.
Summary of the invention
The technical problem to be solved in the present invention overcomes 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 can the air inlet of folding, and the exocoel liquid outlet of exocoel bottom is provided with automatic exhaust device.
Described automatic exhaust device is made up 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; exocoel and tubes connection are stretched out in lower end; protective cover is arranged on the top of gas-liquid separation pipe; and there is gap between gas-liquid separation pipe, protective cover is relative with inner chamber liquid outlet.
Described protective cover is umbrella or plane.
One or more gas-liquid separation groove is provided with in described gas-liquid separation pipe.
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 press technique.
Described steam vent is provided with exhaust gas filter film, exhaust gas filter film is hydrophobic air filter membrane, by ultrasonic welding process or heat seal process or mechanical press technique fixed roof.
Described air inlet is arranged inlet air filtration film, 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 press technique fixed roof.Air inlet is outside equipped with gland, can open, close air inlet.
Described top cover is 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 stops liquid filter membrane and flows into exocoel after being full of inner chamber; first drop in protective cover from inner chamber dripping; protective cover reduces the potential energy of drop, makes drop finally slowly can only fall into exocoel along the peripheral clearance of protective cover.The liquid level flowing into exocoel can raise gradually, and because gas-liquid separation pipe is distributed with gas-liquid separation groove vertically, because its capillary effect, in the absence of external forces, can only pass through air, liquid cannot enter.When liquid falls from protective cover, form the liquid level of certain altitude gradually around gas-liquid separation pipe, along with the rising of liquid level, the air in exocoel is also concentrated from the gas-liquid separation groove of gas-liquid separation pipe and is automatically discharged.When the pressure that liquid level is elevated to liquid generation is greater than the surface tension of gas-liquid separation groove, liquid starts the inside entering gas-liquid separation pipe from gas-liquid separation groove, thus enter in the conduit that is connected with automatic vent automatic liquid-stopping device, because the liquid in exocoel is abundant, the liquid now entering conduit is continuous print.In whole feeding process, in conduit, there will not be the liquid of entrapped air, without the need to special operational approach, save time.
When liquid completes infusion, after only liquid filter membrane automatic liquid-stopping in inner chamber, as needs change infusion bottle proceed infusion time, can this automatic vent automatic liquid-stopping device directly be inserted in new infusion bottle, the air of the air in feed tube and inner chamber can be discharged to the external world by steam vent at this moment on inner chamber automatically, along with the discharge gradually of air, newly to change in infusion bottle liquid and also lasting inflow inner chamber is realized the continuous transfusion function after automatic liquid-stopping.
After whole feeding process completes, due to the existence of automatic liquid-stopping function, to remain in automatic vent automatic liquid-stopping device and liquid in conduit cannot continue infusion below, now, open the air inlet being in normally off, outside air enters into exocoel after being filtered by air inlet, and makes residual liquid continue infusion, ensures that liquid makes full use of.
