Abstract
The utility model relates to fluid control devices field, especially a kind of water valve fault detection alarm device, it comprises alarm indicator lamp, PLC and valve element position detection device, and alarm indicator lamp is connected on the Out let of PLC, and valve element position detection device is connected on the input terminal of PLC.This water valve fault detection alarm device, can monitor water valve fault in real time, and monitoring precisely, effective, can improve the maintenance efficiency of workman, reduces the waste of water.
Description
Technical field
The utility model relates to fluid control devices field, especially a kind of water valve fault detection alarm device.
Background technique
Easily occur after existing toilet flashing valve uses a period of time causing spool can not normal reset and water leakage fault because spring quality declines, because flashing valve is numerous, toilet is numerous, slow by manual inspection, so often can not on-call maintenance and cause water to waste in a large number.
Summary of the invention
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple, can the fault detection alarm device of detection alarm flashing valve spool whether normal reset in time.
In order to achieve the above object, the water valve fault detection alarm device designed by the utility model, it comprises alarm indicator lamp, PLC and valve element position detection device, and alarm indicator lamp is connected on the Out let of PLC, and valve element position detection device is connected on the input terminal of PLC.
Technique scheme, utilize in pushing flashing valve spool water-rinsing process, spool has two limit positions in left and right, and when stopping pushing spool, spool resets under the action of the spring and cuts off the water supply.When valve normally works, reset position is fixed, and valve element position detection device is just arranged on this position and detects spool whether reset to this position.If valve element position detection device can't detect spool, then PLC can not receive the input signal of valve element position detection device, and after time delay (may be in bath), PLC output order lights corresponding alarm indicator lamp.Because each alarm indicator lamp has carried out geocoding, after workman finds that alarm indicator lamp is bright, just can know that fault has appearred in which place toilet flashing valve according to appropriate address coding at once, thus keep in repair in time, decrease water waste.
The water valve fault detection alarm device that the utility model obtains, can monitor water valve fault in real time, and monitoring precisely, effective, can improve the maintenance efficiency of workman, reduces the waste of water.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in the figure, the water valve fault detection alarm device that the present embodiment describes, it comprises alarm indicator lamp, PLC and valve element position detection device, and alarm indicator lamp is connected on the Out let of PLC, and valve element position detection device is connected on the input terminal of PLC.Valve element position detection device is arranged on the position that spring 2 can make spool 1 normal reset.Whether, according to setting, valve element position detection device automatically can detect spool 1 and whether arrive this position, thus realize breaking down to water valve carrying out detection alarm.
Claims (1)
1. a water valve fault detection alarm device, it comprises alarm indicator lamp, PLC and valve element position detection device, it is characterized in that: alarm indicator lamp is connected on the Out let of PLC, and valve element position detection device is connected on the input terminal of PLC.
