Between pipeline on connect pressure regulation filter device, connect oil sprayer on the connecting line between oil inlet and the second gas source,
Solenoid valve is connected at the top of copper bar, the import of solenoid valve connect with the first gas source and receives the gas of the first gas source generation, solenoid valve
Outlet be connected to the nozzle needle piston cavity of resorption in nozzle, the solenoid valve, which connect with control cabinet and receives the switch of electromagnetism, to be referred to
Enable, in the case where solenoid valve conduction, the first gas source generate pressure open the nozzle needle of nozzle, make copper bar air inlet, into
Hydraulic fluid port is connected to the inner cavity of nozzle.
In above scheme, soap bubble is smeared below nozzle.
In above scheme, soap bubble is smeared in the junction of solenoid valve and copper bar.
In above scheme, soap bubble is smeared in the junction of nozzle and copper bar.
The beneficial effects of the utility model are: the nozzle and solenoid valve failure detection device, using the on-off of solenoid valve come
Nozzle operation is controlled, detects the performance of nozzle and solenoid valve, and carry out at each sealing of above-mentioned detection device using soap bubble
Detection improves maintenance efficiency, reduces the rate of breakdown of steel plate surface-spraying jet printer.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other attached drawings.
Fig. 1 is nozzle and solenoid valve failure detection device in the utility model embodiment；
Fig. 2 is the circuit connection diagram of solenoid valve in the utility model embodiment；
Number explanation is as follows in figure: 1 nozzle, 2 copper bars, 3 solenoid valves, 4 air inlets, 5 oil inlets, 6 power supplys, 7 brackets, 8 oil
Day with fog, 9 pressure regulation filter devices, 10 control cabinets, 11 gas sources, 12 gas sources.
Specific embodiment
Keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing 1~Fig. 2
The utility model is described in further detail with specific embodiment.
The nozzle and solenoid valve failure detection device that the present embodiment uses, including 24V power supply 6, copper bar 2, nozzle 1, gas source
11, gas source 12, control cabinet 10 and bracket 7.Nozzle 1 is connected on the mounting surface of copper bar 2, and solenoid valve 3 is mounted on the upper table of copper bar 2
Face, the overall structure after three's connection are mounted on bracket 7, and power supply 6 therein is that solenoid valve 3 and control cabinet 10 are powered.Copper bar 2
Pipeline with the air inlet 4 being connect with gas source 11 and the oil inlet 5 being connect with gas source 12, between air inlet 4 and gas source 11
Upper connection pressure regulation filter device 9(includes pressure reducing valve and water filter), on the connecting line between oil inlet 5 and gas source 12
Oil sprayer 8 is connected, solenoid valve 3 is connected at the top of copper bar 3, the import of solenoid valve 3 connect with gas source 11 and receives the generation of gas source 11
Gas, the outlet of solenoid valve 3 is connected to the nozzle needle piston cavity of resorption in nozzle 1, and solenoid valve 3 connect with control cabinet 10 and receives control
The switch order of case 10 processed, in the case where solenoid valve 3 is connected, the pressure that gas source 11 generates opens the nozzle needle of nozzle 1, makes copper
Air inlet 4, the oil inlet 5 of row 2 is connected to the inner cavity of nozzle 1.
Junction of the present embodiment below nozzle 1, in solenoid valve 3 and copper bar 2, the connection punishment in nozzle 1 and copper bar 2
It Tu Mo not soap bubble.
The present embodiment use nozzle and solenoid valve failure detection device its working principle is that, the present embodiment use 0.7Mpa
Mist of oil replaces paint spray, test nozzles sealing effect and coating spray printing effect.When control cabinet sends instruction control to solenoid valve
Solenoid valve open after, the hole p (import) of solenoid valve is connected to the hole A (outlet), the first gas source generation gas by copper bar air inlet
Hole enters the nozzle needle piston cavity of resorption of nozzle, and when gas pressure reaches 0.5Mpa, nozzle needle is opened, the mist of oil generated by oil sprayer
Enter the inner cavity of nozzle by oil inlet and is sprayed under gas pressure effect.Solenoid valve stops under the out code of control cabinet
When, nozzle needle is closed under the drive of reset spring, and cutting enters the connection chamber between the gas and nozzle of copper bar, the nozzle needle of nozzle
Inner cavity decrease in air pressure where piston, nozzle stop oil spout.Illustrate that nozzle and electromagnetic valve work are normal.
Whether there is bubble to emit such as below nozzle, in the junction of solenoid valve and copper bar, in the junction of nozzle and copper bar
Out, if there is bubble to emerge, illustrate the above-mentioned junction gas leakage of the device.Staff can be according to bubble position to each junction
Sealing be adjusted.
