Abstract
The utility model relates to a pressure controller for a metering tank, which comprises an inlet pipe and an outlet pipe arranged on the metering tank. The inlet pipe is equipped with an inlet valve and the outlet pipe is equipped with an outlet valve. The inlet pipe is connected with a gas source. A pressure sensor is connected with the metering tank by pipelines. The pressure sensor is in communication connection with the pressure controller and the pressure controller is in communication connection with the inlet valve and the outlet valve. The pressure controller is suitable for flow control devices. The pressure in the metering tank of the flow control devices is kept stable, so that the flow of fluid materials can be accurately controlled in the flow control devices.
Description
Technical field
The utility model relates to the technical field of pressure control equipment, refers more particularly to a kind of pressure control device of measuring tank.
Background technique
Flow control device is the device that is used for the control flow rate size.Aborning, the precision of flow control directly has influence on the precision of product.As shown in Figure 1, the structure of existing flow control device is: comprise measuring tank 1, measuring tank 1 is connected with metering pump 2 by pipeline, and metering pump 2 is connected with casting valve 3 by pipeline, and casting valve 3 is connected with measuring tank 1 by Circulation pipe 4.
The working principle of existing flow control device is: in nonproductive period, conveying by metering pump 2, material in measuring tank 1 enters in the casting valve 3 by pipeline, and material enters measuring tank 1 after the circulation port of casting valve 3 enters Circulation pipe 4, and material is in recurrent state; In production period, by the conveying and the metering of metering pump 2, the material in measuring tank 1 enters in the casting valve 3 by pipeline, and material enters extruder after the discharge port of casting valve 3 flows out.Its measuring principle is: the purpose that reaches the control mass flow by the rotating speed of control metering pump 2.
The shortcoming of existing flow control device is: because the meeting respective change when charging or discharging of the pressure in the measuring tank 1, when the pressure in the measuring tank 1 is big, at equal metering pump rotating speed with in the time, the flow of material is inevitable bigger, pressure in measuring tank 1 hour, at equal metering pump rotating speed with in the time, the flow of material is inevitable less, thereby causes the metering of metering pump 2 inaccurate.
The model utility content
Technical problem to be solved in the utility model is: a kind of pressure stability that can make in the measuring tank is provided, thereby makes the pressure control device of the measuring tank that the measuring accuracy of flow control device improves.
For addressing the above problem, the technical solution adopted in the utility model is: the pressure control device of measuring tank, comprise: be arranged on suction tude and steam outlet pipe on the measuring tank, described suction tude is provided with suction valve, described steam outlet pipe is provided with gas outlet valve, and described suction tude is connected with source of the gas, and pressure transducer is connected with measuring tank by pipeline, pressure transducer is connected with the pressure controller communication, and communication is connected pressure controller with gas outlet valve with suction valve.
The beneficial effects of the utility model are: the pressure control device of described measuring tank can make the pressure in the measuring tank be in the stable scope, makes at equal metering pump rotating speed with in the time, and the flow of material is more stable, thereby has improved measuring accuracy.
Description of drawings
Fig. 1 is the structural representation of the pressure control device of the utility model measuring tank;
Among the figure: 1, measuring tank, 2, metering pump, 3, casting valve, 4, Circulation pipe, 5, suction tude, 6, steam outlet pipe, 7, suction valve, 8, gas outlet valve, 9, source of the gas, 10, pressure transducer, 11, pressure controller.
Embodiment
Be described in further detail below in conjunction with the pressure control device of accompanying drawing the utility model measuring tank.
As shown in Figure 1, the pressure control device of measuring tank, comprise: be arranged on suction tude 5 and steam outlet pipe 6 on the measuring tank 1, described suction tude 5 is provided with suction valve 7, described steam outlet pipe 6 is provided with gas outlet valve 8, and described suction tude 5 is connected with source of the gas 9, and pressure transducer 10 is connected with measuring tank 1 by pipeline, pressure transducer 10 is connected with pressure controller 11 communications, and 8 communications are connected pressure controller 11 with gas outlet valve with suction valve 7.
Working principle of the present utility model is: the pressure condition in the pressure transducer 10 real-time monitoring and metering jars 1, when the pressure in the measuring tank 1 surpasses setting value, pressure transducer 10 transfers signals in the pressure controller 11, pressure controller 11 control gas outlet valves 8 are opened, gas in the measuring tank 1 is discharged from steam outlet pipe 6, thereby the pressure in the measuring tank 1 is reduced; When the pressure in the measuring tank 1 is lower than setting value, pressure transducer 10 transfers signals in the pressure controller 11, pressure controller 11 control suction valves 7 are opened, and source of the gas 9 pours gas in the measuring tank 1 through suction tude 5, thereby the pressure in the measuring tank 1 is raise.Thereby the pressure in the measuring tank 1 is in the stable scope, makes at equal metering pump rotating speed with in the time, the flow of material is more stable, has improved the measuring accuracy of metering control.
