Detailed description of the invention
Fig. 1 is aerating and exhaust device structural schematic diagram of the invention；
Fig. 2 is vent valve control module design drawing of the invention；
In Fig. 2: 1-control equipment, 2-inflation platforms, 3-vent valves, 4-vent valve control modules, 5-vent valves electricity
Source, 6-servo valve sockets, 7-first diodes, the 8-the second diode, 9-resistance, 10-photo-couplers, 11-compound open
It closes, the 12-the first solenoid valve socket, 13-second solenoid valve sockets.
Specific embodiment
A kind of specific embodiment of the invention are as follows: the control composition of whole systems includes: control equipment 1, vent valve
Control module 4, inflation platform 2, vent valve 3, vent valve power supply 5.The servo valve cable parallel connection that wherein control equipment 1 exports goes out two
A servo valve line, one end are inserted in inflation 2 other end of platform and are connected with the servo valve socket 6 of vent valve control module 4, and it is same to solve instruction
The problem of step control, allows vent valve 3 to be controlled by computer room instruction when needing to deflate, when control equipment 1 provides deflation instruction
When by vent valve control module 4 open vent valve 3, deflation speed is accelerated with this.Servo valve socket 6, when control equipment 1 provides
It deflates and a negative current is generated by servo valve cable when instructing；First diode 7, one-way conduction, when electric current is flowed by the end D
Conducting, closure when being flowed by A；The resistance 9 of 200 Ω, resistance 9 of connecting are formed into a loop；Photo-coupler 10 is used to control circuit
Combination switch 11；First solenoid valve socket 12, vent valve power supply 5 is connected on this socket, and A is positive, and B is negative；Two or two pole
Pipe 8, one-way conduction.Second solenoid valve socket 13 is connected on vent valve 3, and the end A on plug and solenoid valve socket 12A are terminated
Vent valve 3 is opened after logical.
Another specific embodiment of the invention is: connecting circuit diagram with conducting wire form according to Fig.2, in Fig. 1
The servo valve line for controlling equipment output is divided into two, one end is connect with inflation platform, the servo valve socket 6 in the other end and Fig. 2
It docks, the vent valve power supply 5 in Fig. 1 is docked with the first solenoid valve socket 12 in Fig. 2, vent valve line one end and Fig. 2 in Fig. 1
