As shown in connection with fig. 1-4;
the invention provides a continuous liquid quantitative precise extraction machine 1000 which comprises a three-way pipe A10, a three-way pipe B20, a liquid precise quantitative extraction device A30, a liquid precise quantitative extraction device B40, a one-way valve A50 for controlling liquid to flow into the liquid precise quantitative extraction device A30 in a one-way mode, a one-way valve B6060 for controlling liquid to flow into the liquid precise quantitative extraction device B40 in a one-way mode, a one-way valve C70 for controlling liquid to flow out of the liquid precise quantitative extraction device A30 in a one-way mode, and a one-way valve D80 for controlling liquid to flow out of the liquid precise quantitative extraction device B40 in a one-way mode;
the first end and the second end of the three-way pipe A10 are respectively provided with the check valve A50 and the check valve B60, and the first end and the second end of the three-way pipe A10 are respectively communicated to the liquid precise quantitative extraction device A30 and the liquid precise quantitative extraction device B40;
the first end and the second end of the three-way pipe B20 are respectively provided with the check valve C70 and the check valve D80, and the first end and the second end of the three-way pipe B20 are respectively communicated to the liquid precise quantitative extraction device A30 and the liquid precise quantitative extraction device B40.
Based on the above, it can be understood that the liquid precision quantitative extraction device a30 and the liquid precision quantitative extraction device B40 are arranged in parallel, and it should be noted that the speed of extracting liquid and the speed of discharging liquid are all arranged to be the same, and the third end of the tee pipe a10 is arranged to be a liquid inlet end, and the third end of the tee pipe B20 is arranged to be a liquid outlet end.
The method comprises the following steps of:
step 2, driving the liquid precise quantitative extraction device A30 to discharge the liquid precisely extracted by the liquid precise quantitative extraction device A30 from the third end of the three-way pipe B20;
step 3, driving the liquid precise quantitative extraction device A30 to continuously and quantitatively and precisely extract liquid from the third end of the three-way pipe A10, and simultaneously driving the liquid precise quantitative extraction device B40 to synchronously discharge the liquid quantitatively and precisely extracted by the liquid precise quantitative extraction device B40 from the third end of the three-way pipe B20;
step 4, driving the liquid precise quantitative extraction device A30 to continuously and quantitatively and precisely extract liquid from the third end of the three-way pipe A10, and simultaneously driving the liquid precise quantitative extraction device B40 to synchronously discharge the liquid quantitatively and precisely extracted by the liquid precise quantitative extraction device B40 from the third end of the three-way pipe B20;
step 5, driving the liquid precise quantitative extraction device B40 to continuously and quantitatively and precisely extract the liquid from the third end of the three-way pipe A10, and simultaneously driving the liquid precise quantitative extraction device A30 to synchronously and precisely extract the liquid which is quantitatively and precisely extracted by the liquid precise quantitative extraction device A30 from the third end of the three-way pipe B20;
and step 4 and step 5 are circularly reciprocated, namely, the invention can continuously perform quantitative precise extraction on the liquid and discharge the quantitative precisely extracted liquid.
From this, it is possible to summarize:
after the check valve A50, the check valve B60, the check valve C70 and the check valve D80 control the liquid flow, when the liquid precise quantitative extracting device A30 performs the precise quantitative extraction of the liquid, the liquid precise quantitative extracting device B40 can synchronously discharge the precisely quantitative extracted liquid, and when the liquid precise quantitative extracting device B40 performs the precise quantitative extraction of the liquid, the liquid precise quantitative extracting device A30 can synchronously discharge the precisely quantitative extracted liquid, so as to perform the cyclic reciprocating motion, even if the invention can continuously perform the precise quantitative extraction of the liquid and discharge the precisely quantitative extracted liquid into the container to be filled, such as a liquid filling bottle, a liquid filling bag, a liquid filling tank and the like, so that the requirement of the precise quantitative extraction of the liquid with relatively high flow rate and flow rate can be effectively met, therefore, the practicability is high and the use reliability is high.
Preferably, in the technical scheme, the invention further comprises a three-way pipe C90 and a three-way pipe D100;

when the liquid precise quantitative extraction device A30 quantitatively and precisely extracts liquid from the third end of the three-way pipe A10 through the liquid inlet/outlet A31, the liquid precise quantitative extraction device B40 synchronously discharges the liquid quantitatively and precisely extracted by itself from the liquid inlet/outlet B41 through the third end of the three-way pipe B20, in the process, the check valve A50 is automatically opened by hydraulic pressure, the check valve B60 is automatically closed by hydraulic pressure, the check valve C70 is automatically closed by hydraulic pressure, the check valve D80 is automatically opened by hydraulic pressure, only the liquid is allowed to quantitatively and precisely flow into the liquid precise quantitative extraction device A30 through the third end of the three-way pipe A10 and the liquid inlet/outlet A31 in sequence, and only the liquid quantitatively and precisely extracted by volume in the liquid precise quantitative extraction device B40 is sequentially discharged from the liquid inlet/outlet B41 and the third end of the three-way pipe B20 in sequence;
when the liquid precise quantitative extraction device B40 quantitatively and precisely extracts liquid from the third end of the three-way pipe A10 through the liquid inlet/outlet B41, the liquid precise quantitative extraction device A30 synchronously discharges the liquid quantitatively and precisely extracted by the liquid precise quantitative extraction device A30 from the liquid inlet/outlet A31 through the third end of the three-way pipe B20, in the process, the check valve A50 is automatically closed by hydraulic pressure, the check valve B60 is automatically opened by hydraulic pressure, the check valve C70 is automatically opened by hydraulic pressure, the check valve D80 is automatically closed by hydraulic pressure, only the liquid is allowed to quantitatively and precisely flow into the liquid precise quantitative extraction device B40 through the third end of the three-way pipe A10 and the liquid inlet/outlet B41 in sequence, and only the liquid precisely and precisely extracted by the liquid precise quantitative extraction device A30 is allowed to sequentially discharge from the liquid inlet/outlet A31 and the third end of the three-way pipe B20 in sequence;
therefore, when the liquid is quantitatively and precisely extracted, the liquid extracting continuity can be ensured to be good without interruption.
Further, in the implementation, the liquid precise quantitative extraction device a30 comprises a piston type liquid extraction member a301 and a control member a302 for controlling the piston type liquid extraction member a301 to work to precisely and quantitatively extract liquid;

Preferably, the control member a302 includes a screw driving linear module a3021 disposed in an up-and-down direction, and a connecting block a3022 disposed on the screw driving linear module a3021 and capable of moving up and down under the control of the screw driving linear module a 3021;

Therefore, when the screw rod transmission linear module A3021 works and controls the connecting block A3022 to drive the piston rod A3013 and the piston A3012 to move upwards in a precise stroke, the liquid flowing into the third end of the three-way pipe A10 can be quantitatively and precisely extracted to the liquid quantitative extracting cylinder A3011; when the screw rod transmission linear module A3021 works and controls the connecting block A3022 to drive the piston rod A3013 and the piston A3012 to move downwards according to a precise stroke, the screw rod transmission linear module A3021 can extrude out the liquid quantitatively and precisely extracted from the liquid quantitatively extracting cylinder A3011 outwards and sequentially discharge the liquid through the liquid inlet and outlet A31 and the third end of the three-way pipe B20; it should be noted here that, for a liquid with a high flow rate and a high flow velocity, the working speed of the lead screw transmission linear module a3021 may be correspondingly increased to increase the speed at which the connection block a3022 is controlled to drive the piston rod a3013 and the piston a3012 to move upward according to a precise stroke, and in a specific implementation, specific adjustment is performed according to specific situations.

Preferably, the control component B402 includes a screw rod transmission linear module B4021 disposed along the vertical direction and a connection block B4022 disposed on the screw rod transmission linear module B4021 and capable of moving up and down under the control of the screw rod transmission linear module B4021;
