Description
Technical field
The utility model relates to a kind of air compressor self-draining arrangement.The technical field that belongs to the storage or the distribution of gas or liquid.
Background technique
At present, the pressurized air that factory uses is generally all produced by air compressor, makes this pressurized air get into gas tank, is transported to each through pipeline then and uses point.The air temperature that is got in the gas tank by air compressor generally all is about 80 ° of C, therefore, and in gas tank and pipeline, because the action of thermal difference of external environment condition makes airborne vapor condensation become water droplet to accumulate in the gas tank bottom.Factory air receives the influence of self environmental factor bigger, and various compositions are very complicated in the air, and the ponding of formation is very big to the corrosion harmfulness of gas tank bottom.Traditional method is by special messenger department clothes at present, the regularly artificial outlet valve discharging ponding of opening.This method needs artificial timing to control, and the manual control reliability receives certain limitation, also causes waste of manpower resource simultaneously.
Summary of the invention
The purpose of the utility model is the defective to above-mentioned existing technology, provide a kind of can prevention and alleviate by condensation ponding the corrosion of gas tank bottom is set off an explosion wait do not endanger, the while can save the air compressor self-draining arrangement of the human resources of regular discharge ponding.
For realizing that the technological scheme that above-mentioned purpose the utility model is taked is: a kind of air compressor self-draining arrangement; Form by the solenoid valve on the waste pipe that is installed in the compressor gas tank with to the control circuit that the switch of said solenoid valve carries out automatic timing control; Said control circuit comprises: the normally opened contact and the solenoid valve of the timing closing contact of rotary switch, the time relay, the said time relay, auxiliary reclay, said auxiliary reclay; One end of said rotary switch and power supply L line join and an end of the coil of the other end and the said time relay joins; The other end of the coil of the said time relay and power supply N line join; One end of said timing closing contact and power supply L line join and an end of the coil of the other end and said auxiliary reclay joins; The other end of the coil of said auxiliary reclay and power supply N line join; One end of said normally opened contact and power supply L line join and an end of the coil of the other end and said solenoid valve joins, and the other end of the coil of said solenoid valve and power supply N line join.Said control circuit is positioned at electric appliance control box.
One end of said rotary switch and power supply L line join and an end of the coil of the other end and the said time relay joins, and the other end of the coil of the said time relay and power supply N line join, during closed rotary switch; The coil of the time relay gets electric, and an end of said timing closing contact and power supply L line join and an end of the coil of the other end and said auxiliary reclay joins, and the other end of the coil of said auxiliary reclay and power supply N line join; The timing closing make contact, the coil of auxiliary reclay gets electric, and an end of said normally opened contact and power supply L line join and an end of the coil of the other end and said solenoid valve joins; The other end of the coil of said solenoid valve and power supply N line join; The normally opened contact of auxiliary reclay is closed, and the coil of solenoid valve gets electric, the valve open of solenoid valve; Discharge pipe line is opened, and accomplishes to discharge water automatically.The time relay is a cycle time relay, and solenoid valve automatically cut out according to the time lag of setting, and circulating open close prolongs the gas tank purpose in working life thereby reach regular discharging gas tank bottom ponding like this.
This device is made up of the time relay, solenoid valve, auxiliary reclay and some pipeline parts, and is simple and compact for structure, cheap.And, can adjust the time set of the time relay at any time according to the degree of factory's working environment and ambient temperature variation, change the time lag of gas tank bottom ponding discharging, improve the utilization efficiency of device to greatest extent.
According to the utility model; The pressurized air that can discharge the generation of factory air compressor is condensate in the ponding of gas tank bottom owing to temperature descends in gas tank and pipeline running; Therefore the working life that can improve equipment; Prevention and alleviate the corrosion of gas tank bottom to be set off an explosion and wait harm, the human resources that the while can be saved regular discharge ponding by condensation ponding.
