On the table.
Preferably, the appearance and size of valve mounting base 4 is length × width x thickness=130mm × 120mm × 25mm, and size is suitable
In, it is easy for installation.
The operation principle of the present apparatus is：Valve mounting base 4 is internally provided with inlet channel and outlet passageway, detection gas from
Inlet channel entrance enters, and after 12 grades of 5 internal conversion valve 52 of air solenoid valve are opened, air is through valve mounting base 4
The channel of interior φ 8 enters the import of 12 grades of air solenoid valves 5；When the connection of electromagnetic coil 53 to 12 grades of air solenoid valves 5
After power supply, the air at air inlet from outlet passageway through flowing out again inside 12 grades of air solenoid valves 5.It is aobvious according to air manometer
The pressure value shown is easy to distinguish, can quickly, correctly judge whether 12 grades of air solenoid valves 5 have event to phenomenon of the failure
Barrier.The detection device can effectively check the failure in actual production, improve production efficiency.
Below by taking 12 grades of air solenoid valves 5 as an example, the use process of the present apparatus is illustrated：
With reference to Fig. 5, when detection, 12 grades of air solenoid valves 5 screw 6 is fixed in device valve mounting base 4, is used in combination
4 screws are fixed.First the socket 51 of 12 grades of air solenoid valves 5 is not given to power on, 12 grades of air solenoid valves 5 should be located at this time
In closed state；Then pressure reducing valve 1 and the first one-way throttle valve 21 are opened, is shown according to the air manometer installed at air inlet
The air pressure value shown regulates the pressure of experiment air；First air manometer 31 can monitor in real time empty at air inlet
The pressure of gas is adjusted the one-way throttle valve at air inlet, makes inlet air if air pressure is bigger than normal or less than normal at air inlet
Pressure reaches requirement.The exit of the entrance of the first fabrication hole and venthole uses screw 8 to seal in detection process, and the second work
The exit in skill hole is also sealing state.
After the completion of preparation, power on to the socket 51 of 12 grades of air solenoid valves 5, is arranged in air solenoid valve
Servo valve 55 inside 5 shell 56 is just opened, and intake air acts on the big piston of changeover valve 52 through servo valve 55
Left side pushes changeover valve 52 to move to right, and to make the outlet of air solenoid valve 5 be communicated with entrance, the air of entrance is through 12
Grade air solenoid valve 5 is flowed out from exit.If exit has air stream to go out, then the air manometer in exit will be shown
The size of pressure value, which can be used as the foundation of failure judgement, in actually detected, be carried out living to 12 grades of air electromagnetism
When detection, it may appear that following several situations：
Situation one：When the socket 51 of 12 grades of air solenoid valves 5 is not switched on power supply, 12 grades of air solenoid valves 5
Servo valve 55 is in the closed position, and air outlet slit is not communicated with entrance.Air pressure that the pressure gauge 1 of entrance should be shown and
The pressure for providing air source is consistent.If pressure is less than the pressure of air source at pressure gauge 1, in the feelings of external each pipe joint No leakage
Under condition, it can determine that 52 possible position of changeover valve inside 12 grades of air solenoid valves 5 is incorrect, there are leakage phenomenons.
Situation two：When the socket 51 to 12 grades of air solenoid valves 5 powers on, servo valve 55 is in open position
It sets, servo valve 55 and changeover valve 52 should move accordingly, make 12 grades of 5 air outlet slits of air solenoid valve and entrance phase
It is logical.The air pressure and the offer pressure of air source shown when the pressure gauge 1 of 12 grades of 5 entrances of air solenoid valve is consistent, and goes out
When the air pressure that pressure gauge 2 is shown at mouthful is 0, it can determine that the servo valve 55 inside 12 grades of air solenoid valves 5 or turn
The operating position for changing valve 52 is incorrect.
Situation three：When repeatedly powering on to the socket 51 of 12 grades of air solenoid valves 5,12 grades of 5 works of air solenoid valve
Making state should stablize, normally, i.e., servo valve 55 and changeover valve 52 should move accordingly and operating position is normal, air
Outlet will communicate every time with entrance.When the pressure gauge 1 of 12 grades of 5 entrances of air solenoid valve is shown with exit pressure gauge 2
Air pressure it is sometimes consistent sometimes inconsistent when, this phenomenon can determine that repeatability that 12 grades of air solenoid valves 5 work not
Stablize, needs replacing repairing.
The principles of the present invention are also applied to other similar valve detections.Such as the pressure used on engine
Switch, which is the air pressure for experiencing some position, inside have metal bellows and a pair of contact.Work as hair
After motivation high pressure rotating speed reaches a certain standard state, the air come from compressor just enters pressure switch.It is opened when entering pressure
When the air pressure of pass is less than its setting, the switch contact inside pressure switch is closed under spring force, connects letter
Number circuit.We can give the air that pressure switch entrance provides certain pressure, by the break-make of detection switch contact lug, come
Judge whether pressure switch is connected in claimed condition and be closed contact.
