Abstract
The utility model discloses a positive pressure air exhausting device which comprises a blast pump, a mobile phase liquid storage tank connected with the blast pump, a high pressure advection pump connected with the mobile phase liquid storage tank, and an air exhausting tee connected with the high pressure advection pump, wherein the blast pump, the mobile phase liquid storage tank and the high pressure advection pump are connected with the air exhausting tee by liquid transporting pipelines, and an air exhausting pipe and an analysis fluid way are arranged on the air exhausting tee; a high pressure resistant bottle cover is arranged at the top of the mobile phase liquid storage tank, the mobile phase liquid storage tank is made of glass or PVC (polyvinyl chloride) materials, and the capacity of the mobile phase liquid storage tank is 1L; and the blast pump is a diaphragm pump. The positive pressure air exhausting device has the beneficial effects that (1) the structure is simple; and (2) when bubbles exist in the high pressure advection pump, the blast pump can be used for increasing the pressure of mobile phase, the mobile phase and the bubbles in the high pressure advection pump can flow out from the air exhausting pipe under the action of the pressure, so as to realize the automatic air exhausting.
Description
Technical field
The utility model relates to a kind of venting gas appliance, particularly a kind of malleation venting gas appliance.
Background technique
Instrument such as liquid chromatograph, Ion Chromatograph uses liquid as mobile phase usually, the high pressure constant-flux pump is as the mobile phase thrust power, in the process of using, can not there be bubble to exist in the cavity of requirement high pressure constant-flux pump, because the compression ratio of gas is far longer than liquid, dwindle and amplify and can be along with flow of fluid so can rest under the state of high pressure in the cavity of pump along with the operation of pump, bubble will have influence on the mobile of liquid like this, thereby causes the mobile phase flow rate instability.Therefore, in case after entering bubble in the high pressure constant-flux pump, just need artificial exhaust.At present the mode of artificial exhaust mainly contains two kinds, and a kind of is pump when out of service, the liquid outlet position adopt the injector degassing method with the pump housing in the bubble sucking-off; Another kind is pump when out of service, drives bubble out of the pump housing in the mode that entrance location uses injector to push away water.When adopting the injector degassing method, because the very thin 0.25mm that is generally of pipeline requires great effort when therefore bleeding very much; When adopting injector to push away the mode of water, though vent ratio is easier to, annotate mobile phase because of needs use injector etc. in stream, Ion Chromatograph pipeline difficulty is kept away nonsystematic equipment such as will contacting external injector, causes the pollution of mobile phase easily; This dual mode all needs to disconnect the stream of Ion Chromatograph, complicated operation simultaneously.
The model utility content
Problem to be solved in the utility model is: a kind of simple in structure, the malleation venting gas appliance that can finish exhaust automatically is provided.
In order to solve the problems of the technologies described above, malleation venting gas appliance of the present utility model, the mobile phase liquid container that comprise inflating pump, links to each other, the high pressure constant-flux pump that links to each other with the mobile phase liquid container, the blow-off tee that links to each other with the high pressure constant-flux pump with inflating pump, link to each other by indusion tube between described inflating pump, mobile phase liquid container, high pressure constant-flux pump and the blow-off tee, described blow-off tee is provided with outlet pipe and analyzes stream.
Malleation venting gas appliance of the present utility model, high voltage bearing bottle cap is stamped at the top of described mobile phase liquid container, and described mobile phase liquid container is made by glass or PVC material, and the volume of described mobile phase liquid container is 1L.
Inflate effect in order further to improve, malleation venting gas appliance of the present utility model, described inflating pump are membrane pump.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) when having bubble in the high pressure constant-flux pump, boost to mobile phase by inflating pump, under the effect of pressure, the mobile phase in the high pressure constant-flux pump flows out through outlet pipe together with bubble, finishes the automatic discharge of gas.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, outlet pipe, 2, analyze stream, 3, blow-off tee, 4, the high pressure constant-flux pump, 5, the mobile phase liquid container, 6, indusion tube, 7, inflating pump.
Embodiment
As shown in Figure 1, malleation venting gas appliance of the present utility model, comprise inflating pump 7, the mobile phase liquid container 5 that links to each other with inflating pump 7, the high pressure constant-flux pump 4 that links to each other with mobile phase liquid container 5, the blow-off tee 3 that links to each other with high pressure constant-flux pump 4, link to each other by indusion tube 6 between described inflating pump 7, mobile phase liquid container 5, high pressure constant-flux pump 4 and the blow-off tee 3, described blow-off tee 3 is provided with outlet pipe 1 and analyzes stream 2; High voltage bearing bottle cap is stamped at the top of described mobile phase liquid container 5, and described mobile phase liquid container 5 is made by glass material, and the volume of described mobile phase liquid container 5 is 1L; Described inflating pump 7 is a membrane pump.
When in the high pressure constant-flux pump 4 bubble being arranged, blow-off tee 3 is gone to outlet pipe 1 position, operation inflating pump 7 will be promoted at the air pressure in the mobile phase liquid container 5 about 1MPa, under the effect of pressure, mobile phase can by in the mobile phase liquid container 5 through the indusion tube 6 high pressure constant-flux pump 4 of flowing through, flow out by outlet pipe 1 at last.Mobile phase is in process of flowing, because liquid outlet does not have pressure, so the bubble in the high pressure constant-flux pump 4 can flow out together along with mobile phase, finishes exhaust process.
Exhaust is closed inflating pump 7 after finishing, and blow-off tee 3 is forwarded on the analysis stream 2 of Ion Chromatograph, starts high pressure constant-flux pump 4, and whether judge has bubble to exist in the high pressure constant-flux pump 4, if there is bubble to exist, then restarts exhaust; If there is not bubble, just can carries out chromatography experiment and operate.
