Abstract
The utility model relates to an electromagnetic valve plug, in particular relates to a plug having voltage display function and belonging to a hydraulic electromagnetic valve system, and mainly solves the technical problems that what fault the prior electromagnetic valve has cannot be judged in time when a failure occurs. The utility model has the follow technical proposal that the front line and the zero line or the anode and the cathode of a hydraulic electromagnetic valve plug having voltage display function are connected with a voltmeter in parallel. If the voltmeter is required to display when having failures, the output end of the voltmeter is connected with a sectioning switch. The electromagnetic valve plug is mainly applicable to the fast judgment when the hydraulic electromagnetic valve system has failures.
Description
Technical field:
The utility model relates to a kind of electromagnetically operated valve plug, and particularly a kind of plug of hydraulic electromagnetic valve system of demonstration with voltage can show the voltage of sending into electromagnetically operated valve.In normal use, not only can finish the controlled function of electrotechnical, simultaneously control voltage is carried out clear demonstration, realize under the malfunction the accurate judgement of failure cause.
Background technology:
Electromagnetically operated valve plug one is hydraulic pressure, electrical bond point, is electric finally to the control output point of hydraulic test, also is the input point of hydraulic electromagnetic valve events simultaneously.Extensive application along with hydraulic system, electrical interlock control to hydraulic system also becomes increasingly complex, usually electromagnetically operated valve gets electric output and can pass through controls such as PLC output, relay interlocking, electrical interlocks, and in these complicated controlling units, if the existence of a fault point is arranged, will cause electromagnetically operated valve not exported, in addition the hydraulic system of electromagnetically operated valve own also be cannot see, impalpable, therefore the fault of whole hydraulic system is not easy to find and judge.
The utility model content:
The purpose of this utility model provides that a kind of can to differentiate electromagnetically operated valve be the electric fault or the hydraulic buttery valve plug of the demonstration with voltage of hydraulic system fault when electromagnetically operated valve breaks down, and solves mainly at present that can't in time to differentiate be the technical problem of which kind of fault when electromagnetically operated valve breaks down.
The utility model is realized by following technical scheme: the hydraulic buttery valve plug of demonstration with voltage, and at live wire and zero line pin or anodal and negative pole voltmeter in parallel of hydraulic buttery valve plug.The voltage of reflection electromagnetically operated valve plug input electromagnetically operated valve, thereby the quick judgement when realizing the system failure.If requiring voltmeter is just to show in fault, insert a section breaker at the voltmeter output.
The beneficial effects of the utility model are: by application of the present utility model, can react electric boundary very clearly with the hydraulic pressure coupling part, if the voltage that voltmeter shows is within normal range (NR), then can judge it is hydraulic system fault, if it is undesired that voltage shows, then judge it is electric fault.
Description of drawings:

Fig. 2 general solenoid valve control principle figure
1, electromagnetically operated valve plug, 2, voltmeter, 3, section breaker, 4, peripheral interlocking.
Embodiment:
With reference to Fig. 1,2,
The electromagnetically operated valve plug 1 of demonstration with voltage is inserted on the electromagnetic valve coil, voltmeter 2 is connected in parallel on respectively (these terminals can be alternating current fire wire and zero line pin on the terminals of electromagnetically operated valve plug, also can make the direct current both positive and negative polarity), and insert a section breaker 3, can adopt the standard machinery voltmeter to realize circumscribed, to reduce the surrounding space of electromagnetically operated valve, also can adopt the digital display meter of integrated form, directly be integrated on the plastic casing of electromagnetically operated valve plug, directly be connected with electromagnetic valve coil, voltage with direct measurement electromagnetically operated valve plug input electromagnetic valve coil can show simultaneously, comes into plain view.
If requiring voltmeter is just to show in fault; can switch by section breaker 3 so; at ordinary times section breaker 3 is disconnected; guarantee that the voltage display part is in off-state; the circuit of protection voltage display part is when fault or spot check, when needing to observe magnitude of voltage; the section breaker 3 that closes, the voltage display unit just can normally show the voltage of importing electromagnetic valve coil.
Control principle:
The action of hydraulic system, its control principle is: by the realization sequencing of peripheral electrical interlock, realize automatic function by PLC, by the interlocking of PLC and relay, realize the control principle of present general hydraulic system.When the some control procedures of electrical system process, by electromagnetically operated valve plug 1 input electromagnetic valve coil control voltage, during control hydraulic electromagnetic valve events, realize the action request of on-the-spot mechanical location at last.And these control procedures and control interlocking are distributed in the on-the-spot place that disperses usually, therefore occur causing on-the-spot mechanical location action failure because of unknown causes such as electric or electromagnetic valve cores through regular meeting.
When solenoid control voltage was controlled electromagnetically operated valve by the electromagnetically operated valve plug, electromagnetically operated valve plug voltmeter can correctly show the magnitude of voltage of input.
When breaking down, for example existence of certain fault point in the peripheral interlocking part 4 in electric control theory, electromagnetically operated valve plug 1 just can output voltage so, so electromagnetically operated valve voltmeter 2 does not just have voltage to show that electromagnetic valve coil just can not get.If show normal magnitude of voltage at electromagnetically operated valve plug voltmeter 2, the field apparatus akinesia, faulty component just can be got rid of electricly so, and overhauling emphasis should be in electromagnetic valve core jam or other hydraulic pressure reason.So the electromagnetically operated valve plug of demonstration with voltage can be distinguished electric or hydraulic fault very intuitively.
