As shown in figure 8, the operation principle of safe duplex electromagnetic valve described in the utility model is：Safety dual valve is by two phases
Same two-position three way single valve is constituted, and after two warp knuckle streams, single valve air inlet is linked together with safety dual valve air inlet IN, and two
Link together with the delivery outlet OUT of safety dual valve after the delivery outlet parallel connection of individual single valve, after the air vent parallel connection of two single valves
Connect together with the air vent EXIT of safety dual valve, by two compressed airs for entering pilot solenoid valve into safe duplex
The first gas cavity volume in valve（It is left）2-a, the second gas cavity volume（It is right）Just intersected before 2-b, realized to two in safe duplex
Single valve 1DT, 2DT cross detection, and control, while realizing the peace of 3a, 3b being made up of two single valves and two-position three way magnetic valve
Full dual valve air inlet IN, gas outlet OUT, air vent EXIT Redundant Controls are parallel together.When the two of safety dual valve
Individual pilot solenoid valve 1DT, 2DT coil obtains electric or dead electricity, pilot solenoid valve simultaneously and intersects from the work that valve core of main valve is monitored and controlled
Make the valve core of main valve commutation action of state and rear control safety dual valve.
Safety dual valve described in the utility model can be divided into following three working condition when working：
（1）Safety dual valve no power working condition, i.e. reset state：
Compressed air from the air inlet IN of main valve body 1-1 into inlet chamber 1-a 1-12 after respectively Jing main valve body 1-1 from
Two left single valve air inlet restriction hole 1-d, right single valve air inlet restriction hole 1-e air inlet restriction mouths 1-13 into right single valve inlet plenum 1-b,
Left single valve inlet plenum 1-c inlet plenum 1-2, reach guide's air inlet 2-o and the right side of two pilot solenoid valves 3 by air inlet detection channel
Side guide air inlet 2-e guide air inlet 3-1, in the state of no power, the guide air inlet 3-1 guide of pilot solenoid valve 3
Air inlet 2-o and right side guide's air inlet 2-e disconnects closing with left pilot control opening 2-t and right pilot control opening 2-f, enters
The compressed air of gas detection channel is by the lower blocking of guide's air inlet 3-1 and two valve core of main valve 1-5 of two pilot solenoid valves 3
1-7 is sealed；In original two left single valve valve element control room 1-q and right single valve valve element control room 1-p valve core of main valve control room 1-10
Compressed air discharge from the air vent of pilot solenoid valve 3；The clutch that connects with the gas outlet OUT of safety dual valve, braking
Compressed air Jing gas outlet OUT, discharge chamber 1-n1-4 and air vent EXIT in device discharges air.
Now because two valve core of main valve 1-5 are at the position away from the first proximity switch 4 and the second proximity switch 5, make
First proximity switch 4, the second proximity switch 5 export "off", are input into a peace to the safety control system of punching machine
Complete two valve core of main valve of dual valve are in the signal of telecommunication of reset state.
（2）Safety dual valve energization working condition：
When the coil of two pilot solenoid valves is powered simultaneously, guide's air inlet 3-1 is opened, and the air vent of pilot solenoid valve is closed
Close, compressed air enters the first gas cavity volume (left side) 2-a, the second gas cavity volume from air inlet detection channel respectively（It is right）2-b, the second gas hold
Air inlet（It is right）2-c the first gas cavity volume 2-1 and the second gas cavity volume 2-2, by left, guide's air inlet 2-o and right side guide's air inlet
2-e difference two pilot solenoid valves of Jing, left pilot control opening 2-t and right pilot control opening 2-f pilot control opening 3-2 Jing guide control
Runner 3-3 processed is flowed in left single valve valve element control room 1-q and right single valve valve element control room 1-p valve core of main valve control room 1-10, when
In two main single valve valve element control room 1-10 pressure driven after reaching certain pressure at once two valve core of main valve 1-15 move down and
Left single valve intake valve port 1-h and right single valve intake valve port 1-i main valve intake valve port 1-14 is opened, right single valve exhaust valve port 1- is closed
K and left single valve exhaust valve port 1-m main valve exhaust valve port 1-15.The inlet chamber 1- being connected by the air inlet IN with safety dual valve
The compressed air that 121-a is entered is from two left single valve air inlet restriction hole 1-d, right single valve air inlet restriction hole 1-e main valve air inlet restrictions
The left single valve intake valve port 1-h and right single valve intake valve port 1-i main valve intake valve port 1-14 of mouthful 1-13 Jing, by output cavity 1-j, 1-3,
Gas outlet OUT is in controlled clutch, brake.
It is at being close to the position of the first proximity switch 4 and the second proximity switch 5 after now moving down because of two valve core of main valve 1-5
Put, make the first proximity switch 4 and the second proximity switch 5 export " on ", be input into the safety control system of punching machine
One safety dual valve, two valve core of main valve locate the signal of telecommunication in working order.
（3）Safety dual valve（A single entry valve）Malfunction：
A single entry valve in safety dual valve is out of order（Including the asynchronous of two valve core of main valve actions）, i.e., one master
Valve core 1-5 is opened, another valve core of main valve 1-5 is closed.The left single valve air inlet restriction hole 1-d or right single valve air inlets of compressed air Jing
Throttle orifice 1-e, air inlet restriction mouth 1-13 are from opening（It is preferential to open）The corresponding left single valve intake valve port 1-h of valve core of main valve 1-5
Or right single valve intake valve port 1-i main valve intake valve port 1-14 flow into the right single valve exhaust valve port 1- that another also locates in off position
K, left single valve exhaust valve port 1-m, the left or right single valve exhaust valve port 1-15 of valve core of main valve 1-5, discharge chamber 1-41-n are arranged to air,
Make the clutch being connected with safety dual valve gas outlet OUT, the compressed air pressure in brake decay to its driving pressure it
Under（The 10% of air inlet IN pressure, no more than 0.04MPa）.
Now the valve core of main valve of side is in the position for being close to the first proximity switch 4, another valve core of main valve be in away from
The position of the second proximity switch 5, the output " on " signal of the first proximity switch 4, the second proximity switch 5 export " closing " signal,
The signal of telecommunication of a failure is input into the safety control system of punching machine.
