Abstract
The invention relates to a gas path water induction prevention device for mass spectrometer pretreatment. The gas path water induction prevention device comprises a closed cavity (7), wherein the closed cavity (7) is provided with a gas inlet (1); a gas outlet (5) and a water drain opening (6) are correspondingly formed in the top and the bottom of the closed cavity (7) respectively; a piston valve rod (4) is arranged at the gas outlet (5) and the water drain opening (6) and is connected with one end of a lever (3); the lever (3) is provided with a pivot; the other end of the lever (3) is connected with a floating ball (2); the gas outlet (5) is communicated with a gas suction opening of a mass spectrometer pretreatment device; when a liquid level in the closed cavity is heightened, the floating ball rises up; the lever (3) drives the piston valve rod (4) to be pressed down, so that the gas outlet (5) is closed, and the water drain opening (6) is opened so as to perform overflow prevention water drain; when the liquid level in the closed cavity (7) goes down; the lever (3) drives the piston valve rod (4) to rise up, so that the gas outlet (5) is opened, and the water drain opening (6) is closed to recover a normal working state.
Description
Technical field
The present invention relates to a kind of gas circuit waterproof device of mass spectrometer pre-treatment, specifically, be when detecting for the gas in mass spectrometer gas-liquid mixture, prevent liquid flooding from entering the device of mass spectrometer.Belong to mass spectrometer pretreatment technology field.
Background technology
Mass spectrometer, also known as mass spectrograph, is the different isotopic instrument of separation and detection.Namely according to the principle that charged particle can deflect at elect magnetic field, a quasi-instrument of separation and detection material composition is carried out by the mass discrepancy of material atom, molecule or molecular fragment.
Mass spectrometer is when detecting the gas had in gas-liquid mixture, gas before going into the mass spectrometer, pre-treatment need be carried out, aqueous water contained by removing, but in prior art, mass spectrometric pre-treatment is not enough to remove the large quantity of fluid flowed out due to excessive tank, if do not process, liquid can enter mass spectrometer along air delivering pipeline, will cause measurement result poor accuracy, and even cause damage to instrument.
Summary of the invention
The technical issues that need to address of the present invention are: existing mass spectrometric pre-treatment is not enough to remove the large quantity of fluid flowed out due to excessive tank, and liquid can enter mass spectrometer along air delivering pipeline, will cause measurement result poor accuracy, even causes damage to instrument.
The present invention takes following technical scheme:
A gas circuit waterproof device for mass spectrometer pre-treatment, comprises airtight cavity 7, and described airtight cavity 7 has air inlet 1, and its top and bottom are respectively equipped with corresponding gas outlet 5 and discharge outlet 6, and described gas outlet 5 and discharge outlet 6 arrange a piston valve spindle 4; Described piston valve spindle 4 is connected with one end of lever 3, and lever 3 has fulcrum, and the other end of lever 3 is connected with ball float 2; Described gas outlet 5 is communicated with the air entry of mass spectrometer front processor; When the liquid level in airtight cavity 7 raises, ball float rises, and lever 3 drives piston valve spindle 4 to press down, and gas outlet 5 is closed, and discharge outlet 6 is opened, and carries out anti-overflow draining; When the liquid level in airtight cavity 7 declines, ball float declines, and lever 3 drives on piston valve spindle 4 and lifts, and gas outlet 5 is opened, and discharge outlet 6 is closed, and recovers normal operating conditions.
Further, described piston valve spindle 4 is straight-bar.
Further, described fulcrum is comparatively close to piston valve spindle 4.
Further, the rectangular body shape of described airtight cavity 7 or horizontal cylindrical.
Further, described air inlet 1 is connected with fermentation tank.
Beneficial effect of the present invention is:
1) gas circuit waterproof device structure is simple, is skillfully constructed, and it is convenient to implement.
2) stable and reliable operation, does not need electric component.
3) gas free of losses.
4) cost is lower, good economy performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gas circuit waterproof device of mass spectrometer pre-treatment of the present invention.
In figure, 1. air inlet, 2. ball float, 3. lever, 4. piston valve spindle, 5. gas outlet, 6. discharge outlet, 7. airtight cavity.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1, under normal circumstances, gas enters airtight cavity 7 by air inlet 1, a ball float 2 is included in airtight cavity 7, ball float 2 has the lever 3 of fulcrum can drive piston valve spindle 4 by middle, and be provided with gas outlet 5 on the top of piston valve spindle 4, bottom is provided with discharge outlet 6.Under normal circumstances, ball float 2 is positioned at the bottom of airtight cavity 7 under gravity, so piston valve spindle 4 is in upper, therefore gas outlet 5 is opened, and gas can normally flow through, and in like manner discharge outlet 6 is closed, and gas can not lose.When containing liquid in air inlet, along with the rising of liquid level, drive ball float 2 to rise, drive piston valve spindle 4 to decline by lever 3, while enclosing gas outlet 5, opening water discharge mouth 6 carries out discharge opeing.After fluid discharge, the clear-cutting forestland such as ball float 2 and piston valve spindle 4 are to normal condition.
The feature of the gas circuit waterproof device of mass spectrometer pre-treatment of the present invention is as follows: structure is simple, and stable and reliable operation, does not need electric component, to gas free of losses.
