Abstract
The utility model discloses a standard automatic distributing device for mixed gas, which comprises an electronic balance and an a gas inlet pipe, wherein the output end of the electronic balance is connected with a controller of an electric control valve through a signal processing circuit; the output end of the controller of the electric control valve is connected with the electric control valve; and the electric control valve is connected with the gas inlet pipe. The content of each component filled into a finished gas cylinder can be determined by the difference of readings displayed on the electronic balance, and the opening and closure of valves are controlled by the controller of the electric control valve, so the standard automatic distributing device for mixed gas realizes the automatic filling of component gas, reduces the error of manual operation, guarantees the accuracy of measurement values, avoids the problem of raw material waste brought by excessive filling, improves work efficiency, saves time and labor, and eliminates potential safety hazard caused by component gas leakage because of not simultaneously turning off the valves so as to guarantee safety production.
Description
Technical field:
The utility model relates to a kind of air distributing device of normal mixture body, especially a kind of simple in structure, can guarantee value accurately, increase work efficiency, time saving and energy saving normal mixture body automated gas divider.
Background technology:
At present, the air distributing device that is used for the normal mixture body all is manual operation, when charging into one of them component, pressure tabular value on the necessary attention device panel constantly of operating personnel and the gravimetric value on the electronic balance, when it is worth the definite value of getting well near calculating in advance, operating personnel then should manually turn-off the valve that is arranged on the air inlet pipe (device) rapidly, tighten cylinder valve simultaneously fast ..., all charge in the finished product gas cylinder until all components.Reach ppm level (promptly 10 because the concentration of component of mist is minimum
-6Level), the minimum less than of its quality 1 gram, when valve on the manual-lock air inlet pipe and cylinder valve, there is bigger error in the influx of gas, causes the uncertainty of calibrating gas big, the value accuracy reduces.And normal mixture body component can reach kind more than 20 at most, each component raw material gas need be charged into respectively in the finished product gas cylinder, the component gas that charges in the ban is because operating personnel's valve-off is untimely or the oppositely error of stubborn big valve, when its weighing surpassed the good numerical value of calculated in advance, all gas component that then need charge into thereafter all must be made corresponding adjustment again.Equivalent value exceeds in the time of too much can't remedying, and then must give up this bottle and do again again, causes waste of raw materials.In addition, the calibrating gas component mostly is pernicious gas, does not have shutoff device valve and bottle valve simultaneously as operating personnel, then might cause gas to leak, and exists potential safety hazard.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, provide a kind of simple in structure, can guarantee value accurately, increase work efficiency, time saving and energy saving normal mixture body automated gas divider.
Technical solution of the present utility model is: a kind of normal mixture body automated gas divider, electronic balance and air inlet pipe are arranged, it is characterized in that: the output of described electronic balance is joined by signal processing circuit and electrically-controlled valve controller, the output and the electrically-controlled valve of electrically-controlled valve controller are joined, and electrically-controlled valve is connected on the air inlet pipe.
The difference of the reading that the utility model can show according to electronic balance determines to be filled into each components contents in the finished product gas cylinder, and by the unlatching of electric control valve controller by-pass valve control, realize charging into automatically component gas, can reduce operate miss manually, guarantee the accuracy of value, avoid the waste of raw materials problem brought because of excessive interpolation, also improved simultaneously operating efficiency, time saving and energy saving, eliminated not close simultaneously and cause component gas to leak the potential safety hazard of bringing because of valve, guarantee safety in production.
Description of drawings:
Fig. 1 is the circuit block diagram of the utility model embodiment.
The specific embodiment:
As shown in Figure 1: a kind of normal mixture body automated gas divider, have with the identical Pressure gauge of prior art, thermometer, electronic balance and air inlet pipe, the output of electronic balance is joined by signal processing circuit and electrically-controlled valve controller, the output and the electrically-controlled valve of electrically-controlled valve controller are joined, electrically-controlled valve is connected on the air inlet pipe, the electrically-controlled valve control circuit can adopt single-chip microcomputer, and electrically-controlled valve is used magnetic valve etc.
The course of work:
Before the preparation, earlier according to the saturated vapour pressure of each component gas and densimeter calculate each component needs when adding the finished product gas cylinder to quality and pressure and configure " preset value "; During distribution, numerical value on the electronic balance is consistent with the single-chip microcomputer show value by signal processing circuit, when its during progressively near preset value, the Single-chip Controlling electrically-controlled valve progressively presents closure state, when the gas weight that fills reaches preset value, electrically-controlled valve then moment closure, the blocking-up air inlet pipe, finish charging into of this component.
