It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, small-sized data center computer room accident air draft machine control system described in the utility model, including exhaust blower
1, air-valve opening and closing actuating motor 2, intermediate switch 3, limit switch 4 and connecting terminal 5；Air-valve opening and closing actuating motor 2 winding be
Centre cap winding, two movable contacts k11, k12 of intermediate switch 3 are connect after being shorted with alternating current 220V power firestreak, and centre is opened
Stationary contact k13 is hanging, stationary contact k14 runs in 1 zero line of blower, the stationary contact k15 for closing 3 connects the contact end Z3, quiet of connecting terminal 5
Contact k16 connects the contact end Z2 of connecting terminal 5；Limit switch 4 is double control switch, two movable contacts k21, k22 of double control switch
It is connect respectively with the contact end Z3 of connecting terminal 5, the contact end Z2；The stationary contact k23 of double control switch meets the L1 of centre cap winding
It holds, stationary contact k24 is connect with the end hanging contact Z5 of connecting terminal 5, the end hanging contact Z4 of stationary contact k25 and connecting terminal 5
Connection, stationary contact k26 connect the end L1 of centre cap winding；Contact Z1 end of the tap terminals 0 of centre cap winding through connecting terminal 5
It is connect with the zero curve of alternating current 220V power supply.
In use, a pair of of stationary contact k23, k25 of double control switch are installed on the open position of air-valve, double control switch it is another
The closed position of air-valve is installed on to stationary contact k24, k26.
The working principle of the utility model is summarized as follows:
As shown in Figure 1, air-valve is closed, exhaust blower 1 stops working when working normally；That is: the end L1 of centre cap winding,
The end L2 is connect with the stationary contact k23 of double control switch (limit switch 4), stationary contact k26, at this point, at stationary contact k23, stationary contact k26
Connect in the tap terminals 0 of vacant state, centre cap winding through the zero curve at the contact end Z1 of connecting terminal 5 and alternating current 220V power supply
It connects, air-valve opens and closes 2 power loss of actuating motor and stops working.Meanwhile the stationary contact k14 of the zero line of exhaust blower 1 and intermediate switch 3
Connection, the zero line side of exhaust blower 1 are connect with the zero curve of alternating current 220V power supply；Since the stationary contact k14 of intermediate switch 3 is in hanging
State, therefore exhaust blower 1 is in power failure state and stops working.
As shown in Fig. 2, staff only needs to stir intermediate opens when occurring fire in computer room and needing accident air draft
3 are closed, connect the movable contact k11 of intermediate switch 3 with stationary contact k14, the movable contact k12 of intermediate switch 3 is connect with stationary contact k16
?.At this point, the zero line of exhaust blower 1 is connect by the stationary contact k14 of intermediate switch 3 with the firewire of alternating current 220V power supply, arrange
Blower 1 it is electric after open carry out accident air draft；At the same time, the firewire of alternating current 220V power supply passes through the contact Z2 of connecting terminal 5
End, the stationary contact k26(through double control switch (limit switch 4) are as shown in Figure 1) it is connect with the end L2 of centre cap winding, in
The tap terminals 0 of heart tap winding are connect with the zero curve of alternating current 220V power supply, constitute closed circuit, and air-valve opens and closes actuating motor 2 and obtains
Electricity rotates forward work, and driving air-valve is opened；When air-valve open in place after touch double control switch (limit switch 4) movable contact k21,
K22, as shown in Fig. 2, movable contact k21, k22 of double control switch are connect with its stationary contact k23, k25 respectively, and intermediate switch at this time
3 stationary contact k15 is hanging, therefore air-valve opening and closing actuating motor 2 powers off again after obtaining electric rotating forward task driven air-valve and opening in place,
Not only it had saved electric energy but also had not influenced accident air draft.
After accident air draft, staff only needs to stir intermediate switch 3, as shown in Figure 1, making intermediate switch
3 movable contact k11 and stationary contact k13 connect and disconnects power supply, the movable contact k12 of intermediate switch 3 is connect with stationary contact k15.
At this point, as shown in Fig. 2, the firewire of alternating current 220V power supply passes through stationary contact k15, the contact end Z3 through connecting terminal 5, passes through dual control
Switch (limit switch 4) movable contact k21 and stationary contact k23 connect with the end L1 of centre cap winding, by centre cap around
The tap terminals 0 of group are connect with the zero curve of alternating current 220V power supply, constitute closed circuit, and air-valve opens and closes actuating motor 2 and obtains electric reversion work
Make, driving air-valve is closed；When air-valve close in place after touch double control switch (limit switch 4) movable contact k21, k22 respectively with
Stationary contact k21, k22 connection, as shown in Figure 1；Therefore air-valve opening and closing actuating motor 2 is arrived in power-off reversion task driven air-valve closing
It is powered off again behind position, is restored to initial normal operating conditions as shown in Figure 1.
