The utility model discloses whether can detect the solenoid valve stops the return circuit at normal condition, if the discovery solenoid valve stops the return circuit becoming invalid, then send the warning, inform the field force, manual stopping to go forward, and the repair line way.
Description
Technical field
The utility model relates to a kind of solenoid valve stop loop failure detection loop, belongs to technical field of electricity.
Background technology
The safeguard protection halt circuit of existing equipment is much controlled by solenoid valve, if solenoid valve lost efficacy, the circuit breaking that such as ground wire departs from or connects, so can cause great potential safety hazard.When needs stop, when cannot stop because of line out of service, great loss can be caused.Therefore, design a kind of solenoid valve stop loop failure detection loop, significant to guarantee equipment safety operation.
Utility model content
The purpose of this utility model is to provide a kind of solenoid valve stop loop failure detection loop, detects solenoid valve stop loop and whether is in normal condition, prevent from causing equipment breakdown.
the purpose of this utility model is achieved by the following technical programs:
A kind of solenoid valve stop loop failure detection loop, comprise stop button SB, solid-state relay KA, electromagnetic valve coil YV, pilot lamp HL, described stop button SB and solid-state relay KA coils from parallel connection of coils, one termination DC24V power positive end of parallel circuit, one end of another termination electromagnetic valve coil YV of parallel circuit, another termination DC24V power supply negative terminal of described electromagnetic valve coil YV; The normally closed contact of described solid-state relay KA is connected with pilot lamp HL, and a termination power V+ of series circuit holds, and another termination power V-of series circuit holds.
The purpose of this utility model can also be realized further by following technical measures:
Aforementioned a kind of solenoid valve stop loop failure detection loop, wherein the model of solid-state relay KA is G6B.
Aforementioned a kind of solenoid valve stop loop failure detection loop, wherein the model of stop button SB is LA18.
Aforementioned a kind of solenoid valve stop loop failure detection loop, wherein the model of pilot lamp HL is AD16.
Aforementioned a kind of solenoid valve stop loop failure detection loop, wherein stop button SB is emergency stop push button.
Compared with prior art, the beneficial effects of the utility model are: this invention can detect solenoid valve stop loop and whether be in normal condition, if find that solenoid valve stop loop lost efficacy, then send warning, notify field staff, frontly go manual stopping, and repair circuit.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.As shown in Figure 1, the utility model solenoid valve stop loop failure detection loop, comprise stop button SB, solid-state relay KA, electromagnetic valve coil YV, pilot lamp HL, described stop button SB and solid-state relay KA coils from parallel connection of coils, one termination DC24V power positive end of parallel circuit, one end of another termination electromagnetic valve coil YV of parallel circuit, another termination DC24V power supply negative terminal of described electromagnetic valve coil YV; The normally closed contact of described solid-state relay KA is connected with pilot lamp HL, and a termination power V+ of series circuit holds, and another termination power V-of series circuit holds.Wherein the model of solid-state relay KA is G6B, and the model of pilot lamp HL is AD16, and the model of stop button SB is LA18, or adopts emergency stop push button.
Electric pressure in industrial control circuit is all DC24V usually, stop button is the relay that Long-distance Control stops solenoid valve adhesive, if need to stop so pressing stop button, then stop solenoid valve adhesive, if the line broken circuit at this moment, or stop the power cathode of solenoid valve to disconnect, so cannot perform shut-down operation.
Solenoid valve stops the concrete method of operation of failure detection circuit to be: middle circuit breaking, and so solid-state relay stops adhesive, and its normally closed contact is connected, and pilot lamp is reported to the police; Also can dead electricity if the other end power supply of electromagnetic valve for braking disconnects so solid-state relay, and report to the police.Because solid-state relay resistance is large, the very little electric current of its need just can adhesive, solid-state relay operating current is milliampere level, during adhesive, state is normal, the normal electric current of parking time institute's conducting that do not need is not enough to start stopping solenoid valve completely, the electric current stopping solenoid valve starting needs very large, usually at more than 2A, so stopping solenoid valve can not misoperation.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
