Do not need described liquid delivery system 103 feed fluids at described board equipment 101, and then generate after second control signal of " not needing liquid ", described method enters step 402: described controller 102 receives described the second control signal, in concrete implementation process, described gas control system also comprises a valve control box 104, respectively with described controller 102, described liquid delivery system 103 and described board equipment 101 connect, described valve control box 104 has the valve corresponding with described board equipment 101, therefore, when described controller 102 receives after the second control signal, described the second control signal can be sent to described valve control box 104 and liquid delivery system 103, this valve control box 104 receives after described the second control signal, can carry out this second control signal, control the valve corresponding with the board equipment 101 that sends " not needing liquid " signal in closed condition, like this, liquid delivery system 103 just can not have been supplied with corresponding board equipment 101 liquid.
Receive described the first control signal and this signal is sent to described valve control box 104 at controller 102, and after liquid delivery system 103, described method enters step 403: in the time that described liquid delivery system 103 receives described the second control signal, carry out described the second control signal, so that described gas can not enter described liquid delivery system 103, and stop providing described liquid to described board equipment 101;
In specific implementation process, the concrete structure of described liquid delivery system 103 as shown in Figure 2, because the embodiment of the present application elaborates to this, does not therefore repeat them here.
And in concrete implementation process, the detailed process of step 403 is: when described feed liquor control device 1033 receives after described the second control signal, by carrying out described the second control signal, described feed liquor control device 1033 stops described liquid to be transported in described liquid pulse impact damper 1031 by described inlet 10312, simultaneously, described Intaker controller 1032 can be controlled described air intake opening 10311 and close, so that described gas can not enter in described liquid pulse impact damper 1031.
By the method shown in Fig. 3 and Fig. 4, just can realize in the time that the feed liquor control device 1033 of impact damper front end moves the air intake opening 10311 on controller buffer opens with to gas, air intake opening 10311 in the time that the feed liquor control device 1033 of impact damper front end is out of service on controller buffer closes to stop to gas, thereby just can realize the whether control of air inlet of the air intake opening 10311 on liquid pulse impact damper 1031.
