Degree is compared, and controls each servo valve.
The working principle of the invention is specific as follows:
PLC receives the pressure F1 in the second tracheae 45 that first pressure sensor 44 acquires, and will be in the second tracheae 45
Pressure F1 is compared with the preset pressure F1 in the second tracheae 45, if when the pressure F1 in the second tracheae 45 is greater than the second gas
When preset pressure F1 in pipe 45, PLC, which controls the first servo valve 42, reduces the vapor volume entered in the first tracheae 41, to make
The value of pressure F1 is identical as the value of preset pressure F1 in the second tracheae 45 in second tracheae 45, if the pressure in the second tracheae 45
When power F1 is less than preset pressure F1 in the second tracheae 45, PLC, which controls the first servo valve 42, makes the steaming entered in the first tracheae 41
Tolerance increases, to keep the value of pressure F1 in the second tracheae 45 identical as the value of preset pressure F1 in the second tracheae 45；
PLC receives the pressure F2 in the third tracheae 46 that second pressure sensor 420 acquires, and will be in third tracheae 46
Pressure F2 is compared with the preset pressure F2 in third air inlet pipe 46, if when the pressure F2 in third tracheae 46 is greater than third
When preset pressure F2 in air inlet pipe 46, PLC, which controls the second servo valve 421, to be made to enter the endotracheal vapor volume of the first high pressure compensation
It reduces, thus keep the value of the pressure F2 in third tracheae 46 identical as the value of preset pressure F2 in third air inlet pipe 46, if
When the pressure F2 in third tracheae 46 is less than the preset pressure F2 in third air inlet pipe 46, PLC, which controls the second servo valve 421, to be made
Increase into the endotracheal vapor volume of the first high pressure compensation, to make the value and third air inlet pipe of the pressure F2 in third tracheae 46
The value of preset pressure F2 in 46 is identical；
PLC receives the pressure F3 in the 6th tracheae 413 that third pressure sensor 411 acquires, and will be in the 6th tracheae 413
Pressure F3 be compared with the preset pressure F3 in the 6th tracheae 413, if the pressure F3 in the 6th tracheae 413 is greater than the
When preset pressure F3 in six tracheaes 413, PLC control third servo valve 47 reduces the vapor volume entered in the 4th tracheae 48,
To keep the value of the pressure F3 in the 6th tracheae 413 identical as the value of preset pressure F3 in the 6th tracheae 413, if when the 6th
When pressure F3 in tracheae 413 is less than preset pressure F3 in the 6th tracheae 413, PLC control third servo valve 47 makes to enter the
Vapor volume in four tracheaes 48 increases, thus the value and the default pressure in the 6th tracheae 413 that make the pressure F3 in the 6th tracheae 413
The value of power F3 is identical；
PLC receives the pressure F4 in the 7th tracheae 414 of the 4th pressure sensor 416 acquisition, and will be in the 7th tracheae 414
Pressure F4 be compared with the preset pressure F4 in the 7th tracheae 414, if the pressure F4 in the 7th tracheae 414 is greater than the
When preset pressure F4 in seven tracheaes 414, PLC, which controls the 4th servo valve 419, subtracts the vapor volume entered in the 8th tracheae 418
It is few, to keep the value of the pressure F4 in the 7th tracheae 414 identical as the value of preset pressure F4 in the 7th tracheae 414, if worked as
When pressure F4 in 7th tracheae 414 is less than preset pressure F4 in the 7th tracheae 414, PLC control the 4th servo valve 419 make into
The vapor volume entered in the 8th tracheae 418 increases, to make in value and the 7th tracheae 414 of the pressure F4 in the 7th tracheae 414
The value of preset pressure F4 is identical；
PLC receives the pressure F5 in the tenth tracheae 66 of the 5th pressure sensor 65 acquisition, and will be in the tenth tracheae 66
Pressure F5 is compared with the preset pressure F5 in the tenth tracheae 66, if when the pressure F5 in the tenth tracheae 66 is greater than the tenth gas
When preset pressure F5 in pipe 66, PLC, which controls the 5th servo valve 62, reduces the vapor volume entered in the 9th tracheae 61, to make
The value of pressure F5 in tenth tracheae 66 is identical as the value of preset pressure F5 in the tenth tracheae 66, if when in the tenth tracheae 66
Pressure F5 less than preset pressure F5 in the tenth tracheae 66 when, PLC, which controls the 5th servo valve 62, to be made to enter in the 9th tracheae 61
Vapor volume increase, to make the value phase of the value of the pressure F5 in the tenth tracheae 66 with the preset pressure F5 in the tenth tracheae 66
Together；
PLC receives the pressure F6 in the 11st tracheae 68 of the 6th pressure sensor 69 acquisition, and by the 11st tracheae 68
