Valve carries out Quick air-discharge.
Further, the exhaust valve is communicated with the first gas circuit, the second gas circuit.
Further, the air-channel system further includes third gas circuit, is Valve for compressing tubular liner in the third gas circuit, described
Valve for compressing tubular liner is connected to the first gas circuit.
Further, the Valve for compressing tubular liner uses air-operated solenoid valve.
Further, the air-channel system is fixed on an integrated package and forms module.
Further, the intake valve, proportioning valve, exhaust valve and quick intake valve are all made of air-operated solenoid valve.
Further, the all-in-one machine that the PLC control system is formed using touch screen and PLC.
The utility model has the beneficial effects that
1. the utility model replaces manual pressure to control mobile pressure tank with Self-pressurizing agri, and controls using PLC
Device, when for APG production, they can be used to basis and have designed fixed controlling of production process injecting glue production, and measure practical note
The parameter of adhesive process: such as material feeding pressure and dwell pressure, and production technology practical and being arranged is shown by display screen
Parameter, while can also be by modifying technological parameter etc. on touch screen；Different parameters is developed as needed to show and be arranged
Interface, and actual production process data can be exported, factory's related governing requirements can be met；
2. all valves of the utility model are installed concentratedly on an integrated package, structure is simple, easy for installation, and piping is clear,
It is convenient to repair, and saves space and is convenient for operation inspection problem；
3. the utility model uses touch screen+PLC all-in-one machine, integrated level is good, eliminates many lines, also eliminates processing
Communication therebetween, consequently reduces design problem, simplifies installation process, avoids some fault points, maintenance when
It waits replacement to be also easier to a bit, since integrated level is good, cost can also be reduced, and be occupied little space.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is prior-art illustration；
Fig. 2 is the utility model structure diagram；
Fig. 3 is the utility model use state diagram.
Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in Figure 2,3, a kind of movable tank automatic pressure control device, including PLC control system and air-channel system, PLC
The operation of control system control air-channel system in turn controls the pressure in movable tank.PLC control system uses touch screen
With PLC composition all-in-one machine 8, the air-channel system include intake valve 1, proportioning valve 2, exhaust valve 3 and quickly intake valve 5, into
Air valve 1, proportioning valve 2, exhaust valve 3 and quick intake valve 5 are all made of air-operated solenoid valve.The intake valve 1, proportioning valve 2 form
First gas circuit, the compressed air is by the first gas circuit to movable tank Quick-pressing and accurate pressurization, the quick air inlet
Valve 5 is the second gas circuit, and second gas circuit is to movable tank Quick-pressing, the exhaust valve 3 and the first gas circuit, the second gas circuit
It communicates, movable tank carries out Quick air-discharge by exhaust valve 3.
In order to preferably be additionally provided with third gas circuit in pressure release stage work, the present embodiment, it is in the third gas circuit
