Another termination 0V power end of magnet valve Y2, solenoid valve Y1, Y2.
It is in series with the first electric switch K1 ' and push switch SB1 in every jiggering branch L2, L4, when a jiggering branch
When the first electric switch K1 ' and push switch SB1 in road are closed, opened with the loop-coupled solenoid valve of the jiggering.Also
Be, when in jiggering branch L2 the first electric switch K1 ' and push switch SB1 be all closed when, solenoid valve Y1 could be opened；Work as disk
When the first electric switch K1 ' and push switch SB1 in vehicle branch L4 are closed, solenoid valve Y2 could be opened.
As a preferred embodiment, push switch SB1 is floor push.During jiggering, operator can use double
Foot slams two push switch SB1, while carrying out jiggering operation using jiggering spanner.Therefore, it is provided using the embodiment of the present invention
Jiggering control loop, only need a bit manipulation personnel can be completed jiggering operation, thus improve jiggering operation convenience.
As shown in figure 3, two solenoid valves Y1, Y2 are series in the gas circuit of control host clutch, it is specifically connected on gas
Between road total valve SB3 and host clutch Y3, therefore when two solenoid valves Y1, Y2 are opened, host clutch Y3 ability
It is attracted.
Further, in jiggering control loop provided in an embodiment of the present invention, further include respectively with two jiggering branches
Two operating branches L1, L3 of L2, L4 parallel connection.Because it is in parallel with jiggering branch L2, L4 respectively to operate branch L1, L3, fortune
Turn branch L1, L3 and is also separately connected solenoid valve Y1, Y2.
The second electric switch K2 ' is in series in every operating branch L1, L3.When second in an operating branch is electrical
When K2 ' is closed the switch, the solenoid valve connecting with the operating branch is opened.It is, when second in operating branch L1 electrically opens
When closing K2 ' closure, solenoid valve Y1 is opened；When the second electric switch K2 ' in operating branch L3 is closed, solenoid valve Y2 is beaten
It opens.
Jiggering branch L2, L4 are that respectively solenoid valve Y1, Y2 powers when carrying out jiggering；Operating branch L1, L3 is to set
Respectively solenoid valve Y1, Y2 powers when standby normal operation.
Further include master switch SB2 in jiggering control loop provided in an embodiment of the present invention, as a preferred embodiment, always opens
Pass SB2 is key switch.When master switch SB2 closure, the first electric switch K1 ' is disconnected, the second electric switch K2 ' closure；When

Specifically, further include in jiggering control loop provided in an embodiment of the present invention connect with master switch SB2 first after
Electric appliance K1, the normally closed switch that the first electric switch K1 ' is controlled by the first relay K1.When master switch SB2 closure when, first after
Electric appliance K1 obtains electric, the first electric switch K1 ' disconnection.
It further include logic control element, the second relay K2 and third in jiggering control loop provided in an embodiment of the present invention
Relay K3, logic control element are preferably PLC.The output end of second relay K2 connection PLC, third relay K3 connection are total
The input terminal for third electric switch K3 ' the connection logic control element PLC that switch SB2, third relay K3 are controlled.
When master switch closure, third relay K3 obtains electric, third electric switch K3 ' closure, and logic control element PLC is defeated
High level out, the second relay K2 obtain it is electric, make the second electric switch K2 ' be closed.
Preferably, the normal open switch that the second electric switch K2 ' is controlled by the second relay K2, third electric switch K3 '
The normal open switch controlled by third relay K3.
The concrete application process of jiggering control loop provided in an embodiment of the present invention is as follows:
When equipment runs well, master switch SB2 closure, i.e. key are inserted into key switch and are located at closed position, and first
Relay K1 and third relay K3 all in electricity condition.
The third electric switch K3 ' closure that third relay K3 is controlled, obtains logic control element PLC electric.Logic control
Unit PLC processed exports high level to the second relay K2, obtains the second relay K2 electric, the second electric switch K2 ' closure.
Meanwhile first the first electric switch K1 ' for being controlled of relay K1 disconnect, keep jiggering branch L2, L4 breaking.
At this point, solenoid valve Y1 obtains electric, solenoid valve Y1 opening by operating branch L1；Solenoid valve Y2 is obtained by operating branch L3
Electricity, solenoid valve Y2 are opened.Host clutch Y3 can be connected to by gas circuit with gas circuit total valve SB3, and host clutch Y3 is attracted,
Whole equipment is set to run well.
When equipment needs jiggering, master switch SB2 is disconnected, i.e., key is inserted into key switch and is located at open position, or
Key is extracted from key switch, the first relay K1 and third relay K3 are all in off-position.
The third electric switch K3 ' that third relay K3 is controlled is disconnected, and powers off logic control element PLC.Therefore the
Two relay K2 power-off, the second electric switch K2 ' are disconnected, and make to operate branch L1, L3 open circuit.
Meanwhile first the first electric switch K1 ' closure that is controlled of relay K1, then two pressings are stepped on by operator
Switch SB1 can be such that jiggering branch L2, L4 is connected.
At this point, solenoid valve Y1 obtains electric, solenoid valve Y1 opening by jiggering branch L2；Solenoid valve Y2 is obtained by jiggering branch L4
Electricity, solenoid valve Y2 are opened.Host clutch Y3 can be connected to by gas circuit with gas circuit total valve SB3, and host clutch Y3 is attracted,
To carry out jiggering operation.
In jiggering control loop provided in an embodiment of the present invention include two jiggerings branch L2, L4, and respectively with every
Two solenoid valves Y1, Y2 of jiggering branch L2, L4 connection.Wherein, first is in series on every jiggering branch L2, L4 electrically to open
K1 ' and push switch SB1 is closed, and the first electric switch K1 ' and push switch SB1 are closed at, and could open corresponding electromagnetism
Valve.And two solenoid valves Y1, Y2 must also be opened simultaneously, and gas circuit could be connected, and be attracted host clutch Y3.Therefore, this hair
The jiggering control loop that bright embodiment provides, by the way of the control of double branches, an only branch breaks down or one
When solenoid valve breaks down, unit exception starting not will lead to, so as to significantly improve the safety during jiggering.
