Embodiment
As shown in Figure 1, the fast quantification filling system of the utility model, it includes filter 1, pressure regulator valve 3, speed control
Valve 6, quantitative pot 9 and vacuum pump 13, gas source are sequentially connected pressure regulator valve 3, speed control valve 6 and quantitative pot 9 by filter 1, fixed
The output end of measuring tank 9 and the output end of vacuum pump 13 are connected with workpiece respectively, and the input terminal and output end of quantitative pot 9 are set respectively
It is equipped with solenoid valve 7 and solenoid valve 10, the output end of vacuum pump 13 is provided with solenoid valve 12.
In the present embodiment, the input terminal of pressure regulator valve 3 and output end are respectively arranged with pressure sensor 2 and pressure sensor
4, the pressure of 2 real-time display gas source of pressure sensor, the pressure after the decompression of 4 real-time display pressure regulator valve 3 of pressure sensor.
In the present embodiment, the input terminal of quantitative pot 9 is provided with pressure sensor 8, inflates for real-time display quantitative pot 9
Pressure.
In the present embodiment, the input terminal of speed control valve 6 is provided with low-pressure safety valve 5.
In the present embodiment, the input terminal of workpiece is provided with pressure sensor 11.
In the present embodiment, the output end of vacuum pump 13 is connected with discharge filter 14.
The working principle of the fast quantification filling system of the utility model is as follows:
According to perfect gas, P1V1=P2V2 is theoretical basis at the same temperature.Assuming that P1 is the pressure of quantitative pot 9, V1
For the volume of quantitative pot 9, P2 is the pressure of workpiece, and V2 is pressure after the filling of workpiece, can obtain P2=P1V1/ by P1V1=P2V2
V2 reduces the volume of V1 in the case where the volume V2 of workpiece is constant as far as possible, by controlling the pressure P1 of quantitative pot 9, this
The small fluctuation of sample P1 pressure will become very little to P2 pressure influence.Assuming that V2=100V1, then the fluctuation range of P2 is then
The 1% of P1 thus can control the total amount for being filled with inside workpiece gas by accurately controlling the pressure of P2.
1, quantitative pot is inflated in advance
Gas source is after the filtering of filter 1, specified pressure needed for reaching quantitative pot 9 by the decompression of pressure regulator valve 3, pressure sensing
2 real-time display bleed pressure of device, 4 real-time display of pressure sensor decompression after pressure, after bleed pressure, decompression insufficient pressure or
When excessively high, system can provide alarm.Gas is throttled by speed control valve 6 to limit the flow that system enters quantitative pot 9 after decompression,
Solenoid valve 7 is opened, and fills into gas to quantitative pot 9, and when 8 pressure of pressure sensor reaches P1 setting value, solenoid valve 10 is closed, complete
It is inflated in advance at quantitative pot 9；If hypertonia, the decorum can provide alarm.
2, inside workpiece vacuumizes
In order to enable the purity of filling quantitative gas, first part evacuate workpiece, it is then re-filled with quantitative gas.Workpiece
It is opened by vacuum pump 13, solenoid valve 12, workpiece is evacuated, pressure value is provided by pressure sensor 11, is extracted into specified
Solenoid valve 12 is closed after value, is completed workpiece and is evacuated.
3, quantitative filling
When solenoid valve 7, solenoid valve 12 are closed, solenoid valve 10 is opened.Quantitative filling is completed, solenoid valve 10 is closed.Due to work
Part volume is far longer than quantitative tank volume, and quantitative pot pressure value must fluctuate, and becomes very little to the influence of workpiece pressure value, so as to
The pressure limit of accurate control workpiece.
