Abstract
The utility model discloses an automatic liquid-level control device. The device comprises a pressure sensor arranged at the bottom of a liquid preparation tank for acquiring a hydraulic pressure value of the interior of the liquid preparation tank; a control unit which is connected with the pressure sensor, processes the pressure value returned by the pressure sensor, and outputs a solenoid-valve closure signal if the pressure value reaches a standard set value; and a solenoid valve which is connected with the control unit and responds to the solenoid-valve closure information transmitted by the control unit, the solenoid valve mounted on an input pipe of the liquid preparation tank. The automatic liquid-level control device has the advantages of quick response, small control error and convenient operation, and is simple in structure, easy for production and low in cost, thereby being suitable for popularization.
Description
Technical field
The utility model relates to a kind of automatic control of liquid device.
Background technology
Existing fluid level control device relies on artificial range estimation tank body next door magnetic turnover panel liquid level gauge to control fully, and it is consuming time so not only to require great effort, and can cause artificial mistake or data unreal, and along with the development of medical industry, medicinal dosage standard is also more and more stricter.Therefore develop a kind of jar interior liquid level error control of can accurately estimating out 0.02% according to actual conditions, the device that improves degree of accuracy is imperative.
Summary of the invention
The utility model is directed against the proposition of above problem, and develops a kind of automatic control of liquid device.The utility model adopts technological means following:
A kind of automatic control of liquid device comprises on the output channel that is arranged on the Agitation Tank bottom, is used to obtain the pressure transducer of liquid pressure value in the Agitation Tank; Connect pressure transducer, the force value that pressure transducer is passed back is handled, when force value reaches typical set value, the control module of output closed electromagnetic valve signal; Connect control module, the solenoid valve that the closed electromagnetic valve information that control module is sent responds; Said solenoid valve is installed on the input channel of Agitation Tank.
Further, pressure transducer is a POLYCRYSTAL SILICON PRESSURE SENSORS.
Further, also comprise the connection pressure transducer, the digital displaying meter that its actual measured value and setting value are shown.
Further, also be provided with hand valve on the input channel of Agitation Tank.
The automatic control of liquid device that the utility model adopts has that system response is fast, departure is little and is easy to use.In addition, it is simple in structure, is convenient to produce, and with low costly is suitable for extensive popularization.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment; (remove the literal note among Fig. 1, need add control module 6)
Fig. 2 is the structured flowchart of the said device of the utility model.
Among the figure: 1, solenoid valve, 2, hand valve, 3, Agitation Tank, 4, digital displaying meter, 5, pressure transducer, 6, control module.
Embodiment
Automatic control of liquid device as depicted in figs. 1 and 2; Comprise on the output channel that is arranged on Agitation Tank 3 bottoms; (weight and pressure have corresponding corresponding relation when condition is certain to be used to obtain the pressure transducer 5 of liquid pressure values in the Agitation Tank 3; Just can how many what and force value of liquid in the Agitation Tank 3 be carried out correspondence based on this principle, how much how much what promptly know force value just knows Agitation Tank 3 interior liquid); Connect pressure transducer 5, the force value that pressure transducer 5 is passed back is handled, when force value reaches typical set value, the control module 6 of output closed electromagnetic valve signal; Connect control module 6, the solenoid valve 1 that the closed electromagnetic valve information that control module 6 is sent responds; Said solenoid valve 1 is installed on the input channel of Agitation Tank 3.Said pressure transducer 5 is a POLYCRYSTAL SILICON PRESSURE SENSORS.For making things convenient for the field staff to carry out equipment is monitored, 5 places are connected with digital displaying meter 4 at pressure transducer, are used for sensor practical measurement value and setting value are shown.On the input channel of Agitation Tank 3, also be provided with hand valve 2 for improving degree safe in utilization.Concrete job order is as shown in Figure 1, and soup gets into Agitation Tank according to the arrow direction indication, detects through POLYCRYSTAL SILICON PRESSURE SENSORS, and when the actual value of digital displaying meter equated with the measured value numeral, solenoid valve cut out automatically, guarantees that loading amount is accurate in the Agitation Tank.The solenoid valve virgin state is an opening.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
