Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
The overall structure of the application is as shown in Fig. 2 the compressed gas is controlled automatically by air inlet 1 into the vacuum
In device.As shown in figure 1, the air intake duct 11 of connection air inlet 1 passes through the vacuum way with vacuum solenoid 5 respectively of air dividing plate 4
51 are connected with the air blowing air flue 61 of air blowing magnetic valve 6.Now vacuum way 51 connects vacuum by vacuum valve core 52
Device 7, the floss hole of the vacuum generator 7 are connected with exhaust duct.Vacuum generator 7 in the application is multi-stage vacuum
Device, the multi-stage vacuum generator can be such that its air-extraction function is repeatedly utilized, save compressed air.In addition, vacuum generator 7 can
The selection of single-stage or multistage is carried out according to suitable environment.The other end of air blowing air flue 61 connects main airway by air blowing valve core 62
8 one end, the other end of main airway 8 connect with vacuum port 3.Now, one end of exhaust duct 21 passes through one-way cock 9 and vacuum port
3 connections, the other end is exhaust outlet 2.To reduce the operating noise of the device, muffler 22 is provided with exhaust outlet 2.The application is such as
Shown in Fig. 3, digital display switch 10 is provided with vacuum port 3.Digital display switch 10 is a collection pressure measxurement, shows, is controlled in one
The intelligent high-precision pressure control device of body, while there is simple to operate, cheap, anti-vibration, control accuracy height, use
The features such as long lifespan.Digital display pressure switches can be used in digital display switch 10, because vacuum port 3 is used to connect vacuum source, then vacuum
Pressure value at mouth 3 is the pressure value inside vacuum source, it can thus be concluded that vacuum values corresponding to vacuum source.The application directly uses
Digital display vacuum switch is measured and judged to its vacuum values, is improved the accuracy of detection data, be ensure that working effect.This
Application switchs the vacuum values that 10 pairs of its vacuum ports 3 are vacuum source using digital display and measured, while carries out numerical value to it and preset
It is fixed.Now digital display switch 10 can according to the difference of actual measured value and setting value to vacuum solenoid 5, air blowing magnetic valve 6 and
The control of one-way cock 9, the integrated automation performance of the device is drastically increased, reduces the working strength of staff,
Improve operating accuracy simultaneously.
When being operated, staff carries out the pre-input of the setting value of digital display switch 10 first, is then compressed
Air is passed through.Compressed air enters air intake duct 11 by inlet port 1, is then divided by air dividing plate 4 for twice air-flow, the twice
Air-flow is respectively enterd in the vacuum way 51 of vacuum solenoid 5 and the air blowing air flue 62 of air blowing magnetic valve 6.In the work of compressed air
Closed respectively with lower vacuum valve core 52 and air blowing valve core 62, that is, stop that compressed air continues to move, now digital display switchs
Vacuum values at 10 pairs of vacuum ports 3 measure.When the actual measured value of digital display switch 10 is not up to setting value, digital display switch
The vacuum valve core 52 of 10 control vacuum solenoids 5 is opened, and now the air blowing valve core 62 of air blowing magnetic valve 6 remains turned-off shape
State.Vacuum valve core 52 open after, compressed air by vacuum way 51 enter vacuum generator 7, and then by exhaust outlet 2 at
Muffler 22 discharge.Meanwhile the control one-way cock 9 of digital display switch 10 is opened.Because one-way cock 9 makes air-flow can only a side
Reverse flow is unable to flowing, therefore the gas when one-way cock 9 is opened in vacuum source is flowed to by one-way cock 9 and is vented
Road 21, discharged finally by the muffler 22 at exhaust outlet 2.The one-way cock 9 can carry out corresponding model according to application demand
Selection.By aforesaid operations process, vacuum source realizes the exhaust reduced pressure operation of inside, so as to ensure the vacuum inside vacuum source
Value reaches setting value.When digital display switch 10 detects that the vacuum values at vacuum port 3 are more than setting value, then vacuum solenoid 5 is true
Empty valve core 52 is closed, and the air blowing valve core 62 of air blowing magnetic valve 6 is opened.Now compressed air leads to master by air blowing air flue 61
Air flue 8, and vacuum source is flowed into finally by the air inlet 3 for being connected to the other end of main airway 8, the process can realize the broken of vacuum source
Vacuumizing, the reasonable and effective use of resource is effectively ensured.The device is by the real-time monitorings of vacuum source vacuum values, so as to right
It is timely adjusted, and job stability has been effectively ensured, while timely adjustment operation avoids larger source of the gas loss,
The reasonable utilization of resource is realized, reduces production cost.Meanwhile the overall structure of the device is stablized compact, realizes space
Reasonable disposition, provide guarantee for product quality.Above-mentioned vacuum solenoid 5 and air blowing magnetic valve 6 can be according to application environments
Difference carries out the selection of the classifications such as direct-acting electromagnetic valve, step direct-acting type electromagnetic valve, while model selection corresponding to progress.
Particular embodiments described above, the purpose of the present invention, technical scheme and beneficial effect are carried out further in detail
Describe in detail it is bright, should be understood that the foregoing is only the present invention specific embodiment, be not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., it should be included in the guarantor of the present invention
Within the scope of shield.
