Description
Technical field
The present invention relates to liquid measure measure and control device, particularly a kind of negative pressure fixed volume formula liquid measure dynamic measurement device.
Background technology
In the field such as medical treatment and chemical industry, it is often necessary to which the liquid measure in liquid storage bottle is measured.Particularly medical field
In, the important control parameter that the instantaneous liquid measure in liquid storage bottle is the tissue liquid sucking-off amount during human body therapy is measured, such as
Instantaneous liquid measure exceeds normal value, then very likely damaged for human body artery, causes blood sucking-off amount excessive.Therefore, if can not
The instance variable that liquid measure exceedes normal value is accurately measured, then malpractice, threat to life safety very likely occurs.
Existing positive displacement liquid measuring device, e.g., sets float in liquid storage bottle, and float position is detected by sensor
Put, and then obtain liquid measure numerical value, but the sensor for detecting float position is mostly to be arranged at intervals, and can not be realized electrodeless（Continuously
It is disconnected）Detection.The also liquid measuring device of Weighing type, it uses pallet and weight sensor to measure the weight of liquid storage bottle, but
It is that its pallet may be only available for its liquid storage bottle carried, nonetheless, liquid storage bottle can not be also carried out effectively fixing, cause to store up
When liquid changes in liquid bottle, bottle is unstable, so as to be interfered to measurement data, and causes to measure and controls inaccurate.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of negative pressure fixed volume formula liquid measure dynamic to measure
Device, it uses negative-pressure adsorption-type that liquid storage bottle is fixed, strong anti-interference performance, realizes the accurate survey to liquid measure in liquid storage bottle
Amount and control.
The present invention solves its technical problem and is achieved through the following technical solutions：
A kind of negative pressure fixed volume formula liquid measure dynamic measurement device, it is characterised in that：Including pallet, sucker, negative pressure line
And weighing sensor, sucker is installed on pallet top, the air nozzle connection negative pressure line that sucker center is fixedly mounted, pallet is fixed on
Weighing sensor top.
Moreover, also include a filter pad that can be placed in sucker center.
Moreover, installing solenoid valve block in negative pressure line, negative pressure line is connected to negative pressure source, solenoid valve block by magnetic valve
It is connected to CPU control units.
Moreover, connecting pressure measurement sensor in negative pressure line, it is single that the pressure measurement sensor is connected to CPU controls
Member.
Moreover, described weighing sensor connection sensor signal lines, weighing sensor are connected by sensor signal lines
To CPU control units.
Moreover, described CPU control units connection liquid dynamical output display unit and alarm unit.
The advantages of the present invention are：
1. a negative pressure fixed volume formula liquid measure dynamic measurement device, it is internally provided with a sucker pallet, the sucker
It is connected to negative pressure source, during work, the fixation to liquid storage bottle is realized by suction disc vacuum pumping, its adsorptive pressure can reach 60~
70Kg, absorption affinity is very big, and the liquid storage bottle of achievable all kinds of not co-contents rigidly fixes, and overcomes liquid measure in liquid storage bottle to change counterweight
The interference of quantity sensor measurement data, realize the purpose in real time and accurately measuring dynamic value.
2. a negative pressure fixed volume formula liquid measure dynamic measurement device, filter pad is placed at sucker center, so as to play waterproof
Dustproof effect, to keep the normal use of negative pressure source.
3. a negative pressure fixed volume formula liquid measure dynamic measurement device, it is provided with negative pressure line and is connected to CPU control lists
The pressure measurement sensor of member, and automatically controlling for negative pressure is realized by CPU control units, during use, when negative pressure reaches
During certain numerical value, then negative pressure source（Pump）It is stopped；After a long time use, when negative pressure leaks, negative pressure source is opened automatically
Open.
4. a negative pressure fixed volume formula liquid measure dynamic measurement device, the connection liquid dynamical output display of CPU control units is single
Member, personnel easy to operation intuitively observe real-time measuring data；And by alarm unit, when realizing that measured value deviates normal value
Alarm, so as to ensure processing safety, meet the control requirement of system.
5. scientific structure design of the present invention is reasonable, rigidly fixing for liquid storage bottle is realized by negative-pressure adsorption, overcomes liquid measure to become
Dynamic interference, realize that liquid measure dynamically accurately measures, it is easy to operate, and a set of measurement apparatus, available for all kinds of liquid storage bottles, use
Different sucker combining structures have the advantages of applied widely.
