6.2 Working principle
a) In manual mode, after pressing the manual switch, P2 and A ports of shuttle valve ST-02 are connected, and the compressed air opens DN15 pneumatic valve 1 and pneumatic valve 2. The device starts spray. Pull the manual switch, and the device stops spray.
b) In the turning point state, after the air source is connected, first rotate the stop high-precision control valve to the fully closed state. After the switch action is triggered, the P2 and A ports of shuttle valve ST-02 are connected. The compressed air opens DN15 pneumatic valve 1 and pneumatic valve 2, and the device starts spray. After the delay (delay time 1~30 (± 3)), the device automatically stops spray.
c) Cyclic spray state: after connecting the air source, first confirm that the start and stop high-precision control valve is in the open state, and the device will automatically enter the cycle mode to achieve spray. Rotate the corresponding start and stop high-precision control valve to adjust the charging and discharging time of the air storage in the air tank, so as to change the cycle start and stop time. When someone passes through the area, press the stop button, and the spray will stop immediately. After the delay, the device will automatically start to enter the cycle mode: when someone passes through the area, if the device must be started, press the start button, and the device will immediately enter the spray mode, and automatically cycle; The device is equipped with a remote control button interface, which can achieve simultaneous control of local and remote start and stop.
Rotate the spray regulating flowmeter LZB-3WB counterclockwise, and the compressed air enters the SC80x200 air tank through the two position five way double air control valve 4A420-15P, port A, when the pressure in the air tank reaches 0 At about 2Mpa (the time of spray is controlled by adjusting the gas flow through the flowmeter), the compressed air in the air tank controls the action of No. 1 two position five way single air control valve 4A110-06, the No. 1 two position five way single air control valve 4A110-06P and ports B are connected, the compressed air controls the action of two position five way double air control valve 4A420-15 through ports P and B, the compressed air controls the action of two position five way single air control valve 4A210-08 through ports P and B, the single air control valve 4A210-08P and ports A are closed, the shuttle valve ST-02P1 and ports A are closed, pneumatic valve 1 and pneumatic valve 2 are closed, The unit stops spray.
