Description
Technical field
The utility model relates to quantitative conveyer, is specially adapted to utilize the online or off-line of Low Pressure Chemical Vapor Deposition to produce the quantitative conveyer of a kind of small flow corrosive liquids in the equipment of coated glass.
Background technique
The chemical industry particularly in the industrial production field, often need carry out the corrosive liquids of tiny flow quantity continuously, stablize, evenly, controlled delivery, in the process of its conveying, require pump, pipeline, valve and metering mechanism to have good corrosion resistance, particularly quantitatively the measuring instrument of usefulness must be reliable and stable, show that accurately, control is convenient.Now generally adopt by flow transducer, control instrument, frequency variator, the feedway of the close-loop control mode that motor and pump constituted, flow transducer records flux signal and gives control instrument through isolating transmitter output, control instrument shows instantaneous flow pv value and integrated flux, instrument is according to setting flow sv value, the output control signal is given frequency variator, the aperture of Frequency Converter Control rotating speed of motor or valve is to reach the purpose of control flow rate, but, in the production testing process of reality, the flow transducer of plurality of specifications such as positive displacement, differential pressure type, float type, turbo type, vortex street type, flow transducers such as quality formula and plug-in type all can not satisfy production requirement, mainly are because corrosive liquid directly contacts the probe of flow transducer, cause flow transducer to damage; Be subject to the influence of manifold pressure fluctuation, big in the error of tiny flow quantity fluid metering, precision is low, does not perhaps have the range ability that needs at all; Corrosive liquids also causes the reduction of flow transducer life-span, reliability variation and demonstration to be forbidden and can't effectively control fluid flow, can not carry out continous-stable and produce normally.
The model utility content
The purpose of this utility model is exactly to cause flow transducer to damage and the low defective of flow transducer self precision in order to overcome the existing direct contact liq measurement of use traffic sensor, and a kind of quantitative conveyer of small flow corrosive liquids is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of quantitative conveyer of small flow corrosive liquids, the defeated feeding pipe that comprises storage tank and be connected with storage tank, defeated feeding pipe is provided with control valve, it is characterized in that: other is provided with an anticorrosion charging basket, anticorrosion charging basket is arranged on the pallet that has a pressure transducer, anticorrosion charging basket is connected with described storage tank by defeated feeding pipe, anticorrosion charging basket is provided with defeated discharge nozzle, be provided with transfer pump and Flow valve successively on the defeated discharge nozzle, Flow valve is connected with a drive motor that is used for the control flows metered valve, and described pressure transducer and drive motor are connected with master controller respectively by lead separately.
Described drive motor can adopt stepper motor commonly used or actuating motor.
Described master controller is common integrated terminal control gear, integrated various data-interfaces and corresponding signal adapter, display unit and data processing unit.
This device is measured the variation of corrosion liquid weight indirectly and changed the area of passage of Flow valve simultaneously by control gear by pressure transducer, and is stable to reach control flow rate, makes this device satisfy the quantitative conveying of small flow corrosive liquids.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
Described anticorrosion charging basket is an enclosed construction, and anticorrosion charging basket top is provided with a pneumatic tube, can fill protective gas with in anticorrosion charging basket for the chemical liquid that can not contact with air, makes formation protective atmosphere in liquid top in the charging basket.
Described defeated feeding pipe is provided with solenoid electric valve, and solenoid electric valve is connected with master controller by lead, and corrosive liquids gets off from storage tank, through solenoid electric valve, when anticorrosion charging basket liquid level arrived the setting weight low level, solenoid electric valve was opened, and beginning is reinforced in anticorrosion charging basket; When liquid level arrived a setting weight high position, solenoid electric valve cut out, and stopped to feed in raw material to anticorrosion charging basket, to satisfy continuous, the stable work of this device.
It is in parallel with transfer pump to be provided with a relief valve on defeated discharge nozzle, keeps the output end pressure of transfer pump stable.
The beneficial effects of the utility model are to measure the weight change of corrosion liquid indirectly to arrive control flow rate by the working pressure sensor, changed and directly passed through flow transducer direct and corrosion liquid contact measurement and control flow rate in the past, non-contact structure has been avoided the damage of sophisticated sensor spare, has improved the working life of device; Because by the indirect mode control flow rate, the influence that is subjected to managing the internal pressure fluctuation and carries liquid viscosity during the direct measurement flow avoided, the precision that has improved measurement is with stable, thereby the precision that has improved this device flow is with stable, improve the continuity and the stability of plated film operation, solved the corrosion problems that tiny flow quantity is carried highly corrosive liquid down.
Below in conjunction with drawings and Examples the utility model is further specified.
