, detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated。
As shown in Figure 1 and Figure 2, automatic selling liquid pump metering-type of the present utility model goes out liquid metering system, including liquid storage container 1, metered volume pump 3, bleeder valve 5, controller 7 with sell liquid machine shell 8；
Described metered volume pump 3 includes inlet 32, liquid outlet 33, body 31, feed liquor check valve 34, go out liquid check valve 35, linear reciprocating driving mechanism 36, measurement chamber 37, piston rod 38 and piston head 39, described linear reciprocating driving mechanism 36 is arranged in the middle part of body 31, described measurement chamber 37 is two and is symmetrically arranged in linear reciprocating driving mechanism 36 two ends, described piston rod 38 is respectively arranged at linear reciprocating driving mechanism 36 two ends, described piston head 39 is arranged on piston rod 38, piston head 39 on two ends piston rod 38 is respectively protruding in two ends measurement chamber 37, two measurement chamber 37 are provided with liquid entrance 40 away from one end of linear reciprocating driving mechanism 36, described liquid entrance 40 by tee T respectively with feed liquor check valve 34 and go out liquid check valve 35 and be connected, described inlet 32 is connected with the feed liquor check valve 34 of two measurement chamber 37, described liquid outlet 33 is connected with the liquid check valve 35 that goes out of two measurement chamber 37；
Described liquid storage container 1 is arranged to be sold in liquid machine shell 8, the inlet 32 of described metered volume pump 3 is connected with liquid storage container 1 by input duct 2, the liquid outlet 33 of described metered volume pump 3 is connected with bleeder valve 5 by drain pipe road 4, and described controller 7 is connected with metered volume pump 3 and bleeder valve 5 respectively。
Wherein linear reciprocating driving mechanism 36 can adopt the form of driven by motor linkage or gear-rack drive, it is possible to adopts electromagnetic linear to drive, but is both needed to ensure to drive Overstroke, to ensure the measuring accuracy of metered volume pump 3。For Fig. 2, measurement chamber 37 is positioned at straight line driving mechanism two ends, when driving mechanism drives two ends piston rod 38 to run to the right, left side piston head 39 moves right from left side measurement chamber 37 left end, the feed liquor check valve 34 being connected with left side measurement chamber 37 automatically turns on, go out liquid check valve 35 to be automatically switched off, liquid enters left side measurement chamber 37 from inlet 32 via the liquid entrance 40 of feed liquor check valve 34 and measurement chamber 37, the measurement chamber 37 on the right is then contrary: feed liquor check valve 34 is automatically switched off, go out liquid check valve 35 to automatically turn on, after the liquid measured in measurement chamber 37 sequentially passes through the liquid entrance 40 of the right measurement chamber 37 and goes out liquid check valve 35, export from liquid outlet 33；After the right piston head 39 arrives the right measurement chamber 37 right-hand member, in the right measurement chamber 37, liquid is got rid of completely, linear reciprocating driving mechanism 36 reverse drive, and the liquid that left side measurement chamber 37 measures is discharged, and the right measurement chamber 37 feed liquor again measures。The volume of measurement chamber 37 is the minimum metering output of automatic selling liquid machine, therefore it is required that the volume of measurement chamber 37 disclosure satisfy that the minimum essential requirement amount of automatic selling liquid machine, set the precision of opposed layout measurement chamber 37 further according to the maximum of demand and the volume measurement error of national standard。And take liquid container 6 for the ease of placing, it is preferred that, described in sell liquid machine shell 8 is provided with and take liquid window 9, described drain pipe road 4 extends into and takes in liquid window 9。
Described automatic selling liquid pump metering-type is adopted to go out the metering method of liquid metering system, comprise the steps: that will take liquid container 6 is put into after below bleeder valve 5, first to controller 7 infusion fluid demand, infusion fluid amount is the integral multiple of measurement chamber 37 volume, controller 7 calculates, according to liquid demand, the number of times that linear reciprocating driving mechanism 36 drives piston rod 38 to move, then controller 7 controls bleeder valve 5 and opens, linear reciprocating driving mechanism 36 runs, when after the calculated number of times that piston rod 38 times of exercise reaches, it is out of service that controller 7 controls linear reciprocating driving mechanism 36, bleeder valve 5 is closed, go out liquid to have measured。
When linear reciprocating driving mechanism 36 unidirectional motion once can complete once to measure output, therefore piston rod 38 times of exercise of above-mentioned calculating should be unidirectional motion number of times, and namely linear reciprocating driving mechanism 36 moves back and forth and once then calculates twice times of exercise。Liquid demand is measurement chamber 37 volume how many times, then need to carry out how many times metering output, and controller 7 has only to control linear reciprocating driving mechanism 36 and drives piston rod 38 times of exercise with regard to the output of controllable liquid。
