Preferably, in the present embodiment, second pressure gauge 223 is arranged at the entrance location of tank body 3.In this way, can be with
When avoiding that pipeline is long between tank body 3 and second pressure gauge 223, existing larger pipeline loses along stroke pressure, ensures second
The precision that pressure gauge 223 detects 3 internal gas pressure of tank body, so as to improve the control essence that operation is inflated to tank body 3
Degree.
In addition, in the present embodiment, a valve 4 and connector 5 are additionally provided in the entrance location of tank body 3.Wherein, valve is passed through
Door 4 can control the break-make of 3 import of tank body, and the dismounting that pipeline can be quickly carried out by connector 5 connects.In this way, close valve 4
After can carry out disassembled and assembled freely operation to pumping cells 21 and inflation unit 22, without influencing the gas pressure inside tank body 3.
At this point, when being inflated operation to tank body 3 using the vacuum type inflation system of the utility model, first according to Fig. 1
Pipeline connection between shown carry out system and tank body 3, and each element can work normally in guarantee system.Then, by gas
221 and second control valve 222 of source is closed, and Open valve 4, the first control valve 212 and vacuum pump 211 successively, is led to
It crosses vacuum pump 211 and vacuum pumping is carried out to tank body 3, the air inside tank body 3 is excluded.At the same time, first is passed through
Pressure gauge 213 is monitored the variation of 3 internal gas pressure of tank body during this, wherein, the gas pressure inside tank body 3
When value reaches the design pressure-bearing value of 0 value or tank body 3, you can close vacuum pump 211, stop the vacuum pumping to tank body 3.It connects
It, closes the first control valve 212, keep the opening of valve 4, and open the first control valve 222 and source of the gas 221 successively.This
When, under the pressure differential effect between 3 internal gas pressure of 221 internal gas pressure of source of the gas and tank body, the gas inside source of the gas 221
Body, into the inside of tank body 3, operation is inflated to tank body 3 by the second control valve 222 and valve 4.In gas replenishment process, lead to
It crosses first pressure gauge 223 and air pressure detection is carried out to 3 entrance location of tank body, i.e., the gas pressure inside tank body 3 is detected, when
When the gas pressure value that first pressure gauge 223 detects reaches design requirement, source of the gas 221, the second valve 222 and valve are closed successively
Door 4, so as to complete the charge operation to tank body 3.
Preferably, in the vacuum type inflation system of the utility model, control unit 23 is further included.Meanwhile first control valve
212 and second control valve 222 using solenoid electric valve, and the first control valve 212 and the second control valve 222 pass through signal
Line is attached with control unit 23, so as to carry out break-make switching control to it by control unit 23.In this way, operating personnel only need
Control signal is sent to the first control valve 212 and the second control valve 222 by control unit 23, you can to the first control valve
212 and second control valve 222 carry out the switching of break-make, so as to save manual operation, improve operating efficiency.Wherein, control unit
23 can select PLC system to control, by pre-setting relative program, so as to fulfill the control to different elements.
It is further preferred that the first control valve 212 and the second control valve 222 are associated setting, between the two
Unlatching relation is limited, make the first control valve 212 and the second control valve 222 and meanwhile be closed or one of them
In opening, another is closed.In this way, it can both prevent in vacuum, due to the second control valve
222 accident opens and the discharge to gas in source of the gas 221 occurs, can also avoid in gas replenishment process, due to the first control
The accident of valve 212 opens and the gas in source of the gas 221 is made to leak by the first control valve 212 and vacuum pump 221, so as to protect
Vacuum pumping and the accurate progress of charge operation are demonstrate,proved, ensures the stability and accuracy of operating process.
Wherein, the association between the first control valve 212 and the second control valve 222 is set, and electrical correlation both may be employed and set
It puts, machinery association can also be used to set.
In addition, in the present embodiment, first pressure gauge 213 uses electro connecting pressure gauge, and first pressure gauge 213 passes through
Signal wire is attached with control unit 23.In this way, the pressure signal that the detection of first pressure gauge 213 generates can be transmitted to control
In unit 23, and then control behaviour is carried out to the first control valve 212 and the second control valve 222 according to pressure signal by control unit 23
Make.For example, the lower limiting value of first pressure gauge 213 is set, in this way, during vacuumizing, when first pressure gauge 213
When the pressure value detected reaches setting value, first pressure gauge 213 generates signal and is sent at control unit 23, and controls single
Member 23 directly can carry out shutdown operation to vacuum pump 211, and the first control valve 212 is carried out according to the signal received
Closing control, it might even be possible to continue that the second control valve 222 is controlled to carry out opening operation, so as to carry out air suction process and inflation automatically
Switching between operation realizes the automation of operating process, greatly improves operating efficiency.
Similarly, second pressure gauge 223 can also be selected as electro connecting pressure gauge, and by signal wire by second pressure
Table 223 is attached with control unit 23.In this way, it is set by the pressure upper limit value to second pressure gauge 223, it is possible to
Gas pressure inside tank body in gas replenishment process 3 detect automatically and gas replenishment process is carried out automatically controlling.For example, work as tank
When gas pressure in body 3 reaches the pressure upper limit value of the setting of second pressure gauge 223, second pressure gauge 223 can be to control
Unit 23 sends signal, and then the closing of 221 and second control valve 222 of source of the gas is controlled by control unit 23, so as to be automatically stopped
To the charge operation of tank body 3.
