The utility model discloses a contain nitrogen-blowing appearance gas distribution mouth and flow bleeder mechanism, wherein flow bleeder mechanism contains air cock sleeve pipe, air cock adjusting sleeve pipe and air cock drainage cap, and the air cock sleeve pipe has been cup jointed in nitrogen-blowing appearance gas distribution mouth exit, and the interval is provided with a plurality of bleed mouths on the air cock sheathed tube lateral wall, and air cock adjusting sleeve pipe cup joints in the air cock sleeve pipe outside, and air cock adjusting sleeve's upper portion opening part is connected with air cock drainage cap. The air tap adjusting sleeve and the air tap drainage cap are made of plastics, and the cross section of the air tap drainage cap in the vertical direction is trapezoidal. This technique can more conveniently carry out readjustment to the tolerance of air cock, and air cock adjusting sleeve pipe passes through the displacement and realizes sheltering from to certain number gas outlet, and air cock drainage cap drainage is gaseous, and the air quantity that prevents to blow organic solvent is too big, prevents that partial determinand from being blown away.
Description
Technical Field
The utility model relates to a check out test set field of chemical especially relates to a nitrogen blows gas circuit with airflow divider device.
Background
The working principle of the concentration nitrogen blowing instrument is that nitrogen is discharged through the air outlet and is blown to the lower part to place the organic solvent in the concentration cup, so that the volatilization of the organic solvent is accelerated, and the purpose of concentration is achieved. However, in the detection of organic substances, organic solvents are required to extract the organic substances, and then the organic substances are concentrated to 1ml for subsequent use. The concentrated in-process generally will use nitrogen to blow concentrated appearance, but some nitrogen blow concentrated appearance because the gas outlet internal diameter is great, and the airflow is also great, leads to blowing away partial organic solvent, also can blow away partial determinand for the base member that we detected time measuring adds the mark rate of recovery and is on the low side, and to this phenomenon, we have made partial improvement on current instrument basis, makes the airflow of present instrument satisfy our practical requirement.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes among the prior art nitrogen gas blowing way air current regulation still need the problem of improvement, provide rational in infrastructure, convenient to use's a nitrogen gas blowing way with air current pressure divider device.
The technical solution of the utility model is, a nitrogen blows gas circuit with air current divider device: the nitrogen blowing instrument air distribution nozzle comprises a nitrogen blowing instrument air distribution nozzle and a flow pressure dividing device, wherein the flow pressure dividing device comprises an air nozzle sleeve, an air nozzle adjusting sleeve and an air nozzle drainage cap, the air nozzle sleeve is sleeved at an outlet of the nitrogen blowing instrument air distribution nozzle, a plurality of air guide ports are arranged on the side wall of the air nozzle sleeve at intervals, the air nozzle adjusting sleeve is sleeved outside the air nozzle sleeve, and an upper opening of the air nozzle adjusting sleeve is connected with the air nozzle drainage cap.
The air nozzle sleeve is made of flexible plastic, an inlet of the air nozzle sleeve is in interference connection with an outlet of a gas distributing nozzle of the nitrogen blowing instrument, an airflow contraction opening is formed in the outlet, the diameter of the airflow contraction opening is 0.5-2 mm, and anti-falling convex rings are arranged on the outer sides of the inlet and the outlet.
The semi-section cross section of the air entraining port is trapezoidal, and the opening direction of the air entraining port is inclined upwards.
The air tap adjusting sleeve and the air tap drainage cap are made of plastics, and the cross section of the air tap drainage cap in the vertical direction is trapezoidal.
The number of the air distribution nozzles of the nitrogen blowing instrument is 1-10.
Compared with the prior art, the utility model relates to a nitrogen gas blowing way with air current divider device has following advantage: an air nozzle sleeve is sleeved at the outlet of the air distribution nozzle of the nitrogen blowing instrument, so that the air quantity of the air distribution nozzle can be more conveniently readjusted. The air tap adjusting sleeve realizes the shielding of a certain number of air outlets through displacement, and the air tap drainage cap can realize drainage of gas flowing out of the drainage pipe, so that the excessive air quantity of the organic solvent is prevented from being blown, and part of objects to be detected is prevented from being blown away. The air flow contraction opening can enable blown air to flow directionally, and the anti-falling convex ring can prevent the air tap adjusting sleeve from falling off carelessly in the using process.
