The principle of work of existing volume control device is: in nonproductive period, conveying by volume pump, material in test tank enters in the casting valve by pipeline, cast bar in the casting valve is in the state of stretching out at this moment, material enters test tank after the circulation port of casting valve enters circulation pipe, material is in recurrent state; In production period, by the conveying and the metering of volume pump, the material in test tank enters in the casting valve by pipeline, and the cast bar in this moment casting valve is in retracted mode, and material enters extruder after the discharging opening of casting valve flows out.Its measuring principle is: the purpose that reaches the control mass flow by the rotating speed of control volume pump.
The shortcoming of existing volume control device is: because the meeting respective change when charging or discharging of the pressure in the test tank, when the pressure in the test tank is big, at equal volume pump rotating speed with in the time, the flow of material is inevitable bigger, pressure in test tank hour, at equal volume pump rotating speed with in the time, the flow of material is inevitable less, thereby causes the metering of volume pump inaccurate; Be not closed completely owing to casting valve can cause when producing in addition, thereby cause partial material from circulation pipe, to be back to test tank, thereby cause the metering of volume pump inaccurate, so the measuring accuracy of this volume control device is not high.
The utility model content
Technical problem to be solved in the utility model is: the volume control device that has mass flowmeter that a kind of accurate measurement of volume pump is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the volume control device that has mass flowmeter, comprise test tank, test tank is connected with volume pump by pipeline, volume pump is connected with casting valve by pipeline, and casting valve is connected with test tank by circulation pipe, and the pipeline between described volume pump and the casting valve is provided with mass flowmeter, described mass flowmeter communicates with rotational speed governor and is connected, and described rotational speed governor is connected with the volume pump communication.
Described circulation pipe is provided with intercepting valve, and described casting valve is connected with the controller communication of damming, and the described controller that dams is connected with the intercepting valve communication.
Described casting valve comprises the cylindrical shell of a hollow, the housing sidepiece is provided with charging aperture, one end of housing is provided with discharging opening, the other end of housing is provided with circulation port, the inside of housing is provided with the cast bar, when cast bar expanding-contracting action, charging aperture is connected with circulation port or discharging opening respectively, and described circulation pipe is connected with the circulation port of casting valve.
The beneficial effects of the utility model are: be provided with mass flowmeter on the described volume control device discharge nozzle that has a mass flowmeter, can detect in real time at linear flow rate, and can regulate the rotating speed of volume pump by rotational speed governor according to the variation of flow, make the rotating speed of flow and volume pump be in relative balance state, thereby improved measuring accuracy; On circulation pipe, be provided with intercepting valve in addition, intercepting valve and casting valve are realized synchronization action by the controller that dams, in production period, in the time of the casting valve withdrawal, the close synchronously intercepting valve, thereby solved owing to casting valve being not closed completely when producing, thereby caused partial material to be back to the phenomenon of test tank from circulation pipe, a step has been improved measuring accuracy again.
