System electrification moves valve standard-sized sheet signal input part, and 3 ends of S2 connect temperature relay power supply signal input on ventilation heating system
End.When 1 end of S1,11 terminations are led to and 2 ends, under the state that 21 terminations are logical, and analog valve " fully closed " state, signal
Exporting the valve opening signal input to L1 via 11 ends of S1, final and power supply ground constitutes electric closed-loop path, simultaneously
Electronic valve road standard-sized sheet signal feeds back on ventilation heating system to 21 ends of S1 via the 2 end outputs of S1.As S1 1
End, 12 terminate logical and 2 ends, and in the on state, " standard-sized sheet " state of analog valve, signal is by the 1 of S1 for 22 ends
End output feeds back on ventilation heating system to 12 ends of S1；Synchronous signal exports to 22 ends of S1 via 2 ends of S1
Flowing into L2, final and power supply ground constitutes electric closed-loop path.When 3 ends of S2,31 ends in an on state, analog loop control
The operating contact of relay under system " normally " mode of operation, signal is via the 31 end normal merits of output temperature relay of S2
Can signal；When 3 ends of S2,32 ends in an on state, simulate relay under ventilation heating system " overtemperature " mode of operation
Another group operating contact, signal via S2 32 ends output overtemperature function signals.Shut-off valve signal input part is receiving
After signal input, export to L3 and constitute electric closed-loop path with shut-off valve signal output part.
Beneficial effects of the present invention:
The application of this tester, solves on machine in the case of without part or Short Item, only need to by exerciser with cable plug on machine even
Connect, just can check the service behaviour index of ventilation heating system.Check comprehensively, simple, convenient, solve the numerous of wiring
Trivial problem, time-consuming, improve the work efficiency that energising checks work and the time fixed a breakdown.

Detailed description of the invention
A kind of ventilation heating system exerciser, including double-point double-throw switch S1, single-pole double-throw switch (SPDT) S2, diode display lamp L1,
L2、L3；Wherein,
1 end of S1 connects the fully closed signal input part of electronic valve on ventilation heating system, and 2 ends of S1 connect ventilation heating system
Upper electronic valve standard-sized sheet signal input part, 3 ends of S2 connect temperature relay power supply signal input on ventilation heating system.
When 1 end of S1,11 terminations are logical with 2 ends, under the state that 21 terminations are logical, analog valve " fully closed " state, signal via
11 ends of S1 export the valve opening signal input to L1, and final and power supply ground constitutes electric closed-loop path, the most electronic
Valve road standard-sized sheet signal feeds back on ventilation heating system to 21 ends of S1 via the 2 end outputs of S1.When 1 end of S1,
12 terminations are led to and 2 ends, and in the on state, " standard-sized sheet " state of analog valve, signal is defeated by 1 end of S1 for 22 ends
12 ends gone out to S1 feed back on ventilation heating system；Synchronous signal flows into 22 ends of S1 via the 2 end outputs of S1
L2, final and power supply ground constitutes electric closed-loop path.When 3 ends of S2, in an on state, analog loop Ore-controlling Role is " just for 31 ends
Often " the operating contact of relay under mode of operation, signal is via the 31 end output temperature relay normal function signals of S2；
When 3 ends of S2,32 ends in an on state, simulate another group of relay under ventilation heating system " overtemperature " mode of operation
Operating contact, signal via S2 32 ends output overtemperature function signals.Shut-off valve signal input part is receiving signal input
After, export to L3 and constitute electric closed-loop path with shut-off valve signal output part.
When using this exerciser, this exerciser is connected to temperature relay cable plug on machine, electronic valve plug, shut-off valve
Plug, just can implement function such as:
Temp. control function checks
When S1 is placed in " fully closed " position, S2 is placed in " normally " position, and temperature switch is placed in temperature extreme higher position, now
Exerciser A point receives the 28V direct current signal of component output on machine, and " opening " display lamp L1, shut-off valve display lamp L3 fire
Bright, machine carries out automatic heating functional check.When S1 is placed in " standard-sized sheet " position, " opening " display lamp L1 display lamp puts out
Going out, now exerciser B point receives the 28V direct current signal of component output on machine, now " closes " display lamp L2 display lamp
Bright, shut-off valve display lamp L3 lamp goes out；When S1 is placed in " fully closed " position, and " closedown " display lamp L2 display lamp extinguishes.
When driving cabin temperature height on machine, in exerciser, electronic valve receives " closedown " signal, and now A point receives 28V
Signal, L1 lamp is bright, then S1 is placed in " standard-sized sheet " position, and L1 lamp extinguishes.When driving cabin temperature is low, electricity in exerciser
Dynamic valve receives " opening " signal, and now B point receives 28V signal, and L2 lamp is bright, then is placed in " fully closed " by S2
Position, L2 lamp extinguishes.
Overtemperature prote energising checks
Switch S2 is placed in " overtemperature " position, and now L1 lamp extinguishes.
