Drainage device with power supply detection function

Abstract

The invention discloses a drainage device with a power supply detection function. The drainage device mainly consists of a power supply unit, a drainage unit, an electromagnetic valve unit, a microcircuit unit and a drainage detection button, so that the drainage device is quite simple in overall structure; the microcircuit unit is driven through the drainage detection button, and whether the power supply unit still provides direct current is judged according to the state that an inlet of an electromagnetic valve communicates with or does not communicate with an outlet of the electromagnetic valve, so that early repair is capable of being achieved, the situation of long-term operation of the drainage device is maintained, and the problems of abnormality, damage and the like of the drainagedevice are further solved; and at the same time, any condition that a dry battery provides the direct current is grasped.

Description

technical field [0001] The invention relates to power detection, in particular to a drainage device with power detection. Background technique [0002] In the air compression system, the compressed air usually contains a lot of water vapor, and in order to avoid the failure of the back-end gas equipment or reduce the service life, the compressed air must first pass through a cooler to condense and separate the water vapor, and then Discharge the separated condensed water through a condensed water discharge device. Most air compression systems (such as dairy and brewing process gas, medical gas and breathing gas, packaging and instrumentation gas, semiconductor electronics manufacturing gas, etc.) includes a device for extracting air, a compressed air filter connected to the device and used to filter solid impurities, oil or water in the compressed air, and a compressed air filter connected to the compressed air and An automatic drain control device for storing and draining ...

AI Technical Summary

Problems solved by technology

However, the electronic device can only be effective when the air pressure is energized to allow the electronic device to open the solenoid valve unit to drain water. However, when it is in the automatic drainage mode, it needs to be electrically opened to maintain operation, so it consumes a lot of power, and if the electronic device When damage occurs or the power supply unit has no power supply, the drainage device will be damaged due to the inability to drain water, and the operator will only know to check when it is in an abnormal state
