Below by taking a specific detection process as an example, referring to Fig. 7, the automatic checkout system carry out it is anti-blocking detection and it is airtight
Property detection method and steps it is as follows:
Tested gas ratio valve and square tube component 20 are fixed on stationary fixture 13.The tested gas ratio valve and
There are three valve bodies for square tube component 20, are off valve 211, proportioning valve 212 and sectioning valve 213 respectively.
After fixing tested gas ratio valve and square tube component 20, run to system electrification.On keyboard input module 60
Carry out the operation of detection control.Anti-blocking detection is carried out first, presses start button, makes first movement cylinder 1151 and inflation cylinder
172 execution in 1s, first movement cylinder 1151 push mounting plate 1110 to move straight down, and the first plug 1120 is quasi-
Really block the nozzle 214 on tested gas ratio valve and square tube component 20, inflation cylinder 172 drive pneumatic head 171 it is mobile allow into
Air flue 1711 is connected to the air inlet 210 of gas ratio valve and square tube component 20.
Three valve bodies on gas ratio valve and square tube component 20 obtain electric-opening simultaneously, open air-leakage detector and are set as
It is long logical, and inflated into gas ratio valve and square tube component 20, while opening the wind pressure detector connecting with the first plug 1120,
Entire actuation time is 3s.Wind pressure at the nozzle 214 of wind pressure detector detection at this time, and wind pressure data is fed back into central processing
Device 40.If the wind pressure value at nozzle 214 reaches setting value, central processing unit 40 can issue signal to indicator light display module 50,
Indicator light display module 50 shows green light, and expression does not block；If wind pressure value is not up to setting value, central processing unit 40 can be controlled
Red light on indicator light display module 50 lights, and indicates there is blocking, is labeled as substandard product.
After the completion of anti-blocking detection, 1151 power loss of first movement cylinder drives mounting plate 1110 to be returned to initial position.Entirely
Process action 4s continues air-leakage test for the gas ratio valve and square tube component 20 after anti-blocking detection qualification.This
When, 1152 energized action of the second mobile cylinder drives the second direction y of movable plate 1157 along the horizontal plane mobile, switches to second
Plug 1130 acts and continues 5s.First movement cylinder 1151 again the second plug 1130 of electric drive moves straight down, 6s
Interior closure of the formation to the nozzle 214 on gas ratio valve and square tube component 20 switches to air-leakage detector in 7s airtight
Detection.Start to carry out air-leakage test, air-leakage test needs to detect three times.
It detects for the first time, 213 power loss of sectioning valve is closed, other two valve bodies obtain electric-opening.By air intake duct 1711 to combustion
Inflation, makes air pressure reach 15kpa, and carry out the pressure maintaining of certain time in gas proportioning valve and square tube component 20.During pressure maintaining,
If air-leakage detector detects that the air pressure decreasing value in gas ratio valve and square tube component 20 is greater than 25pa, air-leakage detector
Instruction (buzzing and light flash) can be issued, shows that the outside of the inside of sectioning valve 213, outside or proportioning valve 212 is airtight
Property is not up to standard to be marked as substandard product；If air-leakage detector detects the air pressure in gas ratio valve and square tube component 20
Decreasing value is less than 25pa, then is not in warning, shows that the outside of the inside of sectioning valve 213, outside or proportioning valve 212 is airtight
Property is up to standard.
Qualified gas ratio valve and square tube component 20 are detected to first time and carry out second of air-leakage test.First movement
Cylinder 1151 and the movement of 1152 power loss of the second mobile cylinder, are returned to initial position, and 212 power loss of proportioning valve is closed, shut-off valve 211
Electric-opening is obtained with sectioning valve 213.It is inflated by air intake duct 1711 into gas ratio valve and square tube component 20, reaches air pressure
15kpa, and carry out the pressure maintaining of certain time.During pressure maintaining, if air-leakage detector detects gas ratio valve and square tube group
Air pressure decreasing value in part 20 is greater than 50pa, and air-leakage detector can issue instruction (buzzing and light flash), show ratio
The inside air-tightness of valve 212 is not up to standard, is labeled as substandard product；If air-leakage detector detects gas ratio valve and square tube
Air pressure decreasing value in component 20 is less than 50pa, then is not in warning, shows that the inside air-tightness of proportioning valve 212 is up to standard.
Qualified gas ratio valve and square tube component 20, which are detected, to second carries out third time air-leakage test.Second of inspection
Each component actuation when survey remains unchanged, and only closes 211 power loss of shut-off valve, and proportioning valve 212 and sectioning valve 213 obtain electric-opening.
It is inflated by air intake duct 1711 into gas ratio valve and square tube component 20, so that air pressure is reached 15kpa, and carry out certain time
Pressure maintaining.During pressure maintaining, if air-leakage detector detects that the air pressure decreasing value in gas ratio valve and square tube component 20 is greater than
25pa, air-leakage detector can issue instruction (buzzing and light flash), show that the inside air-tightness of shut-off valve 211 is not up to standard
It is marked as substandard product；If air-leakage detector detects that the air pressure decreasing value in gas ratio valve and square tube component 20 is small
In 25pa, is then not in warning, shows that the inside air-tightness of shut-off valve 211 is up to standard.
All components and valve body are finally returned to initial position, close power supply, complete entire anti-blocking detection and air-tightness
Detection process.It is qualified products by anti-blocking detection and the gas ratio valve of air-leakage test three times and square tube component 20, other
For underproof product.
It is worth noting that, in entire anti-blocking detection and air-tightness detection process, all components and valve body open when
Between be adjustable, and the automatic checkout system be suitable for different gas ratio valves and square tube component 20, therefore, first
Plug 1120, the second plug 1130 number can make variation as needed, the wind pressure value, the pressure of pressure maintaining when anti-blocking detection are strong
The setting of degree and pressure reduction values is also required to be arranged according to the design requirement of product.
Automatic checkout system provided in this embodiment, the first plug 1120 of automatic detection device 10 and the second plug
