Technical field
The present invention relates to a kind of spray gun, particularly a kind of spray gun with digital display meter.
Background technology
The atomizing effect of spray gun needs to be controlled by the size of stream pressure, in order to accurately understand external gas
The atmospheric pressure that source enters in spray gun, typically all one digital display pressure apparatus can be set in gun handle position, so as to clearly
Recognize admission pressure, admission pressure regulation can be arrived required pressure value by the personnel of proceeding with one's work by air volume regulating device,
But traditional air volume regulating device typically all need by outside adjust, it is impossible to from gun body in itself on be adjusted because digital display pressure
Sensing station in power apparatus typically at inlet suction port, breeder tube on digital display pressure apparatus directly by inlet suction port with
Sensor position is connected, and directly enters sensor, sensor feedback along breeder tube from the air-flow of inlet suction port access
Data are transmitted, final data is in liquid crystal screen display, and the now really admission pressure of liquid crystal screen display, in gun body in itself
Air volume regulating device when being adjusted, air inlet air pressure rather than the real-time working gas of gun body is shown in digital display pressure apparatus
Pressure, easily allow the staff of observation liquid crystal display to misunderstand, influence actual Flow-rate adjustment, and only air volume regulating device is complete
When full opening, the pressure value shown on digital display meter is just identical with work real-time pressure value, and this gas circuit structure sets and caused
Air volume regulating device and digital display pressure apparatus can not be preferably compatible situation, be easily caused digital display effect can not obtain it is actual should
With causing the waste of function.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of spray gun with digital display meter, and it can be in air volume regulating device not
Under same opening degree, remain that the pressure value shown on digital display meter is just identical with work real-time pressure value, staff can
Real-time monitoring is carried out to pressure according to the pressure value on digital display meter.
The present invention solve the technical scheme that uses of above-mentioned technical problem for：
The present invention discloses a kind of spray gun with digital display meter, including gun body, the pikestaff located at the side-lower of gun body one and is connected to

The application method of the present invention is as follows：
Source of the gas and inlet suction port 3 are attached by flexible pipe first, then open source of the gas, air-flow will pass through inlet suction port 3
Enter directly into air inlet runner 5, the air-flow entered in air inlet runner 5 then can enter valve the very first time by air inlet 14
In telescopic hole 12 in door switch 8, followed by the aperture of telescopic hole 12 full of in installing space 7, now installing space 7 is with living
The port that dynamic hole 6 connects is blocked by valve working of plastics 11, and air-flow will not be entered in movable span 6, and pressure measurement runner 15 and peace
Dress space 7 connects, therefore the air-flow in installing space 7 can then enter directly into pressure measurement runner 15 under gas pressure
Interior, with the flowing of air-flow, air-flow then can flow into passage 20 from pressure measurement runner 15, the position finally flowed to where sensor 19
Put, air-flow air pressure presses to sensor 19, and when perceiving air pressure, sensor 19 will carry out data feedback, finally show
Be shown on liquid crystal display 18, staff can intuitively observe pressure value now by liquid crystal display 18, staff need into
During row work, handle 4 is pressed towards the direction of pikestaff 2, handle 4 will be pushed up by valve needle 10 to valve working of plastics 11
Move, the port plug for seal that valve working of plastics 11 no longer connects to movable span 6 and installing space 7, the gas in installing space 7
Enter in movable span 6, then gone through in the jet runner of gun body 1 therewith, finally sprayed from spray tip.
When valve regulated knob 9 is rotated to vertical direction, air inlet 14 and the complete face in the port of air inlet runner 5, now
Air pressure is maximum；When valve regulated knob 9 is rotated clockwise to incline direction, air inlet 14 and the port part misclassification of air inlet runner 5
Open, when diminishing with relative port area between the two, air pressure slowly diminishes；When valve regulated knob 9 is rotated to horizontal side
Xiang Shi, air inlet 14 stagger completely with the port of air inlet runner 5, and now air-flow is isolated in air inlet runner 5, and air pressure is in closing
State.
Understand in summary, the present invention accesses air-flow by inlet suction port 3, and air-flow first passes around valve switch 8 and entered again
Enter to the position of sensor 19, rather than first pass around sensor 19 and pass through valve switch 8 again, therefore adjusted by valve regulated knob 9
Air pressure after section, can accurately it react to sensor 19, the data that sensor 19 is shown just are current real-time working pressure
Power, the pressure value display mode of this real-time working pressure, it is easy to staff to be pressed by control valve adjusting knob 9 work
Power is adjusted, and reaches optimal atomizing effect, and staff need not be adjusted by the air volume regulating device outside regulation
Pressure, directly it is adjusted by valve regulated knob 9.
