Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, for example the present invention is described in more detail:
In conjunction with Fig. 1, technological scheme of the present invention is such: utilize the feedback of status output contact of the contact analogue switch type butterfly valve of doubleway output relay, see K1 in accompanying drawing.K1 consists of coil and 2 groups of output contacts, is called " C " group and " O " group, wherein the position limit switch of " C " group simulation butterfly valve off status; " O " group simulation butterfly valve is driven the position limit switch of state.Every group of output contact consists of 3 pins, is respectively common port, Chang Kaiduan and normal-closed end.Work as input end, relay coil receives corresponding voltage and makes relay work, and move respectively " C " group and " O " group contact, and common port is connected with Chang Kaiduan, and normal-closed end and common port disconnect.If do not receive working signal, i.e. coil losing electricity, common port is connected with normal-closed end, and common port and Chang Kaiduan disconnect.True butterfly valve all needs the regular hour when opening or cutting out, so added the delay circuit consisting of R1 and C1 in input circlult, has formed the simulation process of the switch of butterfly valve.
Analog circut input end consists of 4 components and parts, R1, and C1, R2, Q1, wherein R1 and R2 are resistance, and C1 is polarity free capacitor, and Q1 is NPN type triode.
The current collection of Q1 is the positive pole of input signal very.
The base stage of Q1 is connected with one end of R2, C1 and R1 respectively.
The other end of R2 is connected with the collector electrode of Q1.
The other end of R1 is connected with the other end of C1, is the negative pole of input signal.
The output terminal of analog circut is by relay K 1, and resistance R 3, R4, R5, R6 and light emitting diode DS1, DS2, DS3, DS4 form.
Relay K 1 has 8 pins, and wherein 2 pins that are control coil, are connected with input cathode with the emitter of Q1 respectively.
Other 6 contacts that pin is 2 groups of normally-open normally-closes.2 groups of output contacts are called " C " group and " O " group, respectively the representative contact of " off status " and the contact of " opening state ".The position limit switch of the "Off" state of " C " group output simulation butterfly valve of relay, the position limit switch of the "On" state of " O " group output simulation butterfly valve of relay.In order to reflect that the working state of butterfly valve, the connection of status indicator lamp adopt intersection connection comprehensively.That is:
The common port of position limit switch all accesses the positive pole of 5VDC power supply.
" C " group normally opened contact is connected with R5 one end, and the other end of R5 is connected with light emitting diode DS3, and the other end of DS3 is connected with the negative pole of 5VDS power supply.DS3 is as the "On" state tutorial light of LOCAL CONTROL.
" C " group normally-closed contact is connected with R4 one end, and the other end of R4 is connected with light emitting diode DS2, and the other end of DS2 is connected with the negative pole of 5VDS power supply.DS2 is as the "Off" state tutorial light of REMOTE CONTROL.
" O " group normally opened contact is connected with R3 one end, and the other end of R3 is connected with light emitting diode DS1, and the other end of DS1 is connected with the negative pole of 5VDS power supply.DS1 is as the "On" state tutorial light of REMOTE CONTROL.
" O " group normally-closed contact is connected with R6 one end, and the other end of R6 is connected with light emitting diode DS4, and the other end of DS4 is connected with the negative pole of 5VDS power supply.DS4 is as the "Off" state tutorial light of LOCAL CONTROL.
In sum, the division of labor of position limit switch is as follows:
The tutorial light of the "On" state of " LOCAL CONTROL " is responsible in " often opening " contact of " C " group position limit switch;
The tutorial light of the "Off" state of " REMOTE CONTROL " is responsible in " normally closed " contact of " C " group position limit switch;
The tutorial light of the "On" state of " REMOTE CONTROL " is responsible in " often opening " contact of " O " group position limit switch;
The tutorial light of the "Off" state of " LOCAL CONTROL " is responsible in " normally closed " contact of " O " group position limit switch.
The working procedure of tutorial light is as follows: when relay coil dead electricity, i.e. butterfly valve closed condition, so the tutorial light DS2 of telecontrol and field control and DS4 light owing to being connected to normal-closed end tutorial light; So and ds1 and ds3 is extinguished owing to being connected to Chang Kaiduan tutorial light, 4 lamp indications are all correct.
When relay coil obtain electric, i.e. butterfly valve open mode, output contact action, so the tutorial light DS2 of telecontrol and field control and DS4 extinguish owing to being connected to normal-closed end tutorial light; So and ds1 and ds3 is lighted owing to being connected to Chang Kaiduan tutorial light, 4 lamp indications are all correct.
The benefit of design is like this: by DS1, and DS2, DS3, the state of DS4 tutorial light can judge the quality of butterfly valve mechanical part, butterfly valve internal end of travel switch, to guarantee the integrity of equipment.
If butterfly valve mechanical part damages, can cause butterfly valve tutorial light to show apparent error; If the state that can directly affect certain several tutorial light is damaged in any contact of 2 groups of position limit switches, by LED status, just can judge which position limit switch exists fault.
The switching circuit that input circlult utilizes R2 and Q1 to form input signal is powered to relay coil, and the delay circuit that utilizes R1 and C1 to form carries out time delay to input end signal, the time that simulation butterfly valve opening process or closing process need.
The working procedure of this invention is such: when input end receives 24VDC voltage (relay coil operating voltage), impact due to delay circuit, this voltage can be loaded into the coil of relay after delay, now 2 of relay groups of output contact actions, triggering butterfly valve tutorial light lights or extinguishes, the switching process of simulation butterfly valve, for the exploitation of industrial control system facilitates.
In sum, core of the present invention is to utilize the output signal of doubleway output relay analogue switch type butterfly valve, and the time that adds delay circuit simulation butterfly valve opening process or closing process needs at input end, utilize the intersection connection of often open/normally closed complementation of output contact to embody the working state of butterfly valve comprehensively.
