Problems solved by technology

[0002] Existing toilet flush valves are prone to water leakage after being used for a period of time due to the deterioration of the spring quality and the failure of the valve core to reset normally. Because there are many flush valves and toilets, manual inspection is slow, so it is often impossible to repair in time and cause water leakage. a lot of waste

Embodiment 1

[0010] As shown in the figure, the water valve fault detection and alarm device described in this embodiment includes an alarm indicator light, a PLC and a spool position detection device. The alarm indicator light is connected to the output terminal of the PLC, and the spool position detection device is connected to the PLC. input terminal. The spool position detection device is installed at the position where the spring 2 can make the spool 1 return normally. According to the settings, the valve core position detection device can automatically detect whether the valve core 1 reaches this position, so as to realize the detection and alarm of whether the water valve fails.

Abstract

The invention relates to the field of fluid control equipment, in particular to a fault detecting and alarming device for a water valve. The fault detecting and alarming device comprises an alarming indicating lamp, a PLC and a valve element position detection device. The alarming indicating lamp is connected to an output terminal of the PLC. The valve element position detection device is connected to an input terminal of the PLC. The fault detecting and alarming device for the water valve can be used for monitoring faults of the water valve in real time, in addition, monitoring is accurate, effects are good, the maintaining efficiency of workers can be improved, and waste of water is reduced.

Description

technical field [0001] The invention relates to the field of fluid control equipment, in particular to a water valve fault detection and alarm device. Background technique [0002] Existing toilet flush valves are prone to water leakage after being used for a period of time due to the deterioration of the spring quality and the failure of the valve core to reset normally. Because there are many flush valves and toilets, manual inspection is slow, so it is often impossible to repair in time and cause water leakage. A lot of waste. Contents of the invention [0003] The object of the present invention is to provide a fault detection and alarm device with simple structure and capable of detecting in time whether the flush valve spool is normally reset or not in order to solve the above technical deficiencies. [0004] In order to achieve the above object, the water valve fault detection and alarm device designed by the present invention includes an alarm indicator light, PLC...
