[0012] The automatic air supplementing system 100, the automatic air supplementing pipeline 1, the first manual valve 11, the one-way valve 12, the automatic regulating valve 13, the pressure transmitter 14, the second manual valve 15, the maintenance pipeline 2, the third manual valve 21, PLC controller 3. DETAILED DESCRIPTION

[0013] The technical scheme in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0014] As Figure 1 The utility model discloses an automatic air supplementing system 100 of air pressure, including first pressure pipe network (not shown in drawing) and second pressure pipe network (not shown in drawing), and the pressure of first pressure pipe network is greater than the pressure of second pressure pipe network, still include: an automatic air supplementing pipeline 1, a maintenance pipeline 2 and a PLC controller 3.

[0015] The input end of the automatic air supplementing pipeline 1 is connected with the first pressure pipe network, and the output end is connected with the second pressure pipe network, and the first manual valve 11, the one-way valve 12, the automatic regulating valve 13, the pressure transmitter 14 and the second manual valve 15 are sequentially arranged on the automatic air supplementing pipeline 1 from the input end to the output end; the PLC controller 3 is connected with the automatic regulating valve 13 and the pressure transmitter 14, the PLC controller 3 receives the signal of the pressure transmitter 14 by inputting the pressure set value in the PLC controller 3, thereby controlling the opening and closing of the automatic regulating valve 13.

[0016] The maintenance pipeline 2 is communicated with the input end and the output end of the automatic air supplement pipeline 1 respectively, and a third manual valve 21 is arranged on the maintenance pipeline 2.

[0017] Working principle: the pressure of the first pressure pipeline network is greater than the pressure of the second pressure pipeline network (for example, the pressure of the first pressure pipeline network is 10 bar, and the pressure of the second pressure pipeline network is 8 bar), and the spinning process needs the linear pressure of the second pipeline network to be stable ± 0.2 bar, and the smaller the fluctuation range is, the more stable it is; because there are many gas points in the workshop, the pipeline network pressure is unstable and often lower than the set value; if the pressure is lower than 8.0 bar at this moment, only the first pressure pipeline network needs to supplement air to the second pressure pipeline network through the automatic air supplement pipeline 1 to reach the required pressure value, without the need to additionally increase the operation of the 8 bar air compressor; in use, the first manual valve 11 and the second manual valve 15 are in the normally open state, and the third manual valve 21 is in the normally closed state; when air supplement is needed, the pressure set value has been input in the PLC controller 3 (the set value is reset according to the actual situation); the PLC controller 3 controls the automatic regulating valve 13 to be opened according to the signal received by the pressure transmitter 14, so that the first pressure pipeline network supplements air to the second pressure pipeline network; when the pressure set value is reached, the PLC controller 3 controls the automatic regulating valve 13 to be closed or the opening degree to be reduced according to the signal received by the pressure transmitter 14; and the one-way valve 12 is arranged on the automatic air supplement pipeline 1, so that when the first pressure pipeline network fails and the pressure is lower than that of the second pressure pipeline network, the pressure of the second pressure pipeline network can be prevented from being reversed; when the automatic air supplement pipeline 1 needs to be maintained, the first manual valve 11 and the second manual valve 15 are closed, and the third manual valve 21 on the maintenance pipeline 2 is opened, so that air supplement is realized through the maintenance pipeline 2, and the maintenance of the automatic air supplement pipeline 1 is realized, which is simple and convenient.

[0018] The automatic regulating valve 13 and the pressure transmitter 14 are arranged, air supplement can be realized according to the requirement, manual operation is not needed, air supplement is stable, the linear output of the pressure can be protected, the one-way valve 12 is arranged, the pressure of the second pressure pipeline network can be prevented from being reversed, the first manual valve 11, the second manual valve 15 and the maintenance pipeline 2 are arranged, and the automatic air supplement pipeline can be used when the automatic air supplement pipeline needs to be maintained. The single air compressor automatic air supplement system has the advantages of simple structure, automatic air supplement, stable air supplement, reduced labor amount and reduced operation number of the air compressor.
