Description
Technical field
The utility model is specifically related to a kind of gas dosing pick-up unit, belongs to measuring apparatus technical field.
Background technology
In gas-liquid separation experiment, need to gather isolated gas, access and measure.The existing gas-metering device in laboratory is primarily of compositions such as glass cylindrical shell, piston, metering scale tables, the gas of gas-liquid separation experiment gained arrives through sample introduction pipeline in the glass cylindrical shell of gauge, pointer indicating graduation on piston, reads scale value and manual calculations air output.The service condition in laboratory shows, the gas meter of this kind of structure, adds the workload of experimenter on the one hand, and the error of artificial reading is larger; The volumetric quantity of meter gaseous is limited on the other hand, can not carry out the automatic collection of gas, access and metering continuously.
Summary of the invention
For the problems referred to above, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, and functional reliability is high, error is little, work efficiency is high, can continue the gas dosing pick-up unit measured.
Gas dosing pick-up unit of the present utility model, comprise measuring apparatus and control device, described measuring apparatus comprises glass cylindrical shell and end cap, described end cap to be coordinated with glass cylindrical shell by screw thread and is connected, described glass inner barrel is provided with piston, described glass cylinder body bottom is fixedly connected with cylinder, be fixedly linked with the lower surface of piston after the cylinder axis of described cylinder runs through glass cylinder body bottom, throughly in described end cap be connected with draft tube and escape pipe, described draft tube and escape pipe are respectively arranged with breather cheek valve and unidirectional air outlet valve, described cylinder is connected with air inlet pipeline, described air inlet pipeline is provided with solenoid valve, the lateral wall of described glass cylindrical shell is fixedly connected with first sensor and the second sensor, described control device comprises microprocessor, display, control knob and driver module, described first sensor, second sensor, display, control knob and driver module are all electrically connected with microprocessor, described solenoid valve and driver module are electrically connected.
The utility model beneficial effect: a kind of structure of the present utility model is simple, functional reliability is high, error is little, work efficiency is high, the gas dosing pick-up unit measured can be continued, during use, the volume of glass cylindrical shell is set by control knob, volume data is stored in microprocessor, during work, microprocessor carrys out Controlling solenoid valve by driver module and cylinder is lost heart, the cylinder axis of cylinder drives piston to move down, until the second sensor stops after piston being detected, gas enters into glass inner barrel by draft tube, and breather cheek valve is now in opening, unidirectional air outlet valve is in closed condition, then microprocessor carrys out Controlling solenoid valve by driver module and makes cylinder charge, the cylinder axis of cylinder drives on piston and moves, until first sensor stops after piston being detected, the gas of glass inner barrel is discharged by escape pipe, and breather cheek valve is now in closed condition, unidirectional air outlet valve is in opening.Complete a metering process by above-mentioned flow process, and the gas volume of metering is the volume of glass cylindrical shell, as repeated the lasting metering that above-mentioned flow process can realize gas; The utility model can realize the lasting metering to gas, and has the advantage that functional reliability is high, error is little, work efficiency is high.
