The invention relates to an automatic drainage device design of a gas control instrument, in particular, when the sensing mechanism detects that the gas passing through the water storage chamber contains moisture, the electromagnetic valve interlocking of the automatic drainage device of the gas control device can be activated. The water is discharged through the vent hole of the base, thereby achieving automatic detection, accurate drainage, effectively blocking impurities in the water, and maintaining the accuracy of the gas control instrument.

According to the general air control instrument (such as air compressor or related equipment required), it is sucked by the gas around the air control instrument for compression, and when the gas control instrument draws in and out of the gas every time, it will The air control instrument contains moisture, dust or floating impurities contained in the gas; therefore, when the gas control instrument is operated for a period of time, it must try to discharge the sewage and dust inside the gas control instrument to avoid blocking the gas control instrument. , with the efficiency of weakening pneumatic tools.

However, at present, most of the cleaning methods are generally provided with a drain valve in the air reservoir of the air control instrument. After the scheduled time is used, the drain valve is opened manually by manual operation, which not only causes the human resources to be unnecessary. Waste, it is also easy to cause the lack of drainage due to human negligence.

The main purpose of the present invention is to avoid the above-mentioned conventional lack of persistence When the sensing mechanism detects that the gas passing through the water storage chamber contains moisture, the electromagnetic valve interlocked by the automatic drainage device of the gas control device is activated, so that the water is discharged through the vent hole of the base, thereby achieving automatic detection and accuracy. Drainage, effectively block impurities in the water, and maintain the accuracy of the gas control instrument.

In order to achieve the above object, the present invention relates to an automatic drainage device for a gas control device, comprising: a housing provided with a water storage chamber; a solenoid valve correspondingly coupled with the water storage chamber and having a base venting hole; and a housing disposed in the housing And interlocking the sensing mechanism of the solenoid valve.
