Automatic drainage device of air compressor

Abstract

The invention discloses an automatic drainage device of an air compressor. The automatic drainage device is of an upper-lower cover closing structure, a covering surface is provided with a sealing ring which is pressed through a bolt so as to realize the upper-lower fixation and seal; a thread connecting hole is connected with an elbow thread hole arranged on the bottom of an air storing tank, so as to realize the seal water conduction; an upper cover limits an uppermost stroke of a floater shaft, the floater shaft is provided with a floater and is hermetically matched with one of screw plugs and can flexibly move upper and down, and the screw plug is provided with drain holes; a limiting push rod limits the highest position of a spring shaft, the spring shaft is hermetically matched with the other plug screw and can do an up-lower movement because of an elastic force action of a spring, and the screw plug is provided with drain holes; a thread base arranged on the bottom of a lower cavity body and the screw plug can realize the screw thread fit, and the seal is realized through compressing the sealing ring. The automatic drainage device provided by the invention has the advantages that the design is ingenious and simple, the buoyancy of water in a cavity body is reasonably utilized to control shaft to move up and down and reset the spring after halt pressure relief, the opening and closing of the drain holes are controlled to realize automatic drainage, and the practicability is strong.

Description

technical field [0001] The invention relates to an automatic drainage device for an air compressor. Background technique [0002] The air compressor is the basic product of industrial modernization. It is often said that electricity and automation have the meaning of full pneumatic; and the air compressor is the core equipment that provides air source power. It converts the mechanical energy of the prime mover (usually an electric motor) A device that generates gas pressure energy is a gas pressure generating device that compresses air. [0003] The air compressor inhales ordinary air, which becomes high-temperature and high-pressure gas after being compressed. The inhaled ordinary air always contains a certain amount of gaseous moisture. With the heat dissipation and cooling of the high-pressure gas, the water vapor in it will be saturated and condensed. Therefore, the air compressor stores air There will always be a lot of water in the tank, and the large amount of water ...

Problems solved by technology

[0003] The air compressor inhales ordinary air, which becomes high-temperature and high-pressure gas after being compressed. The inhaled ordinary air always contains a certain amount of gaseous moisture. With the heat dissipation and cooling of the high-pressure gas, the water vapor in it will be saturated and condensed. Therefore, the air compressor stores air There will always be a lot of water in the tank, and a large amount of water will have a certain negative impact on the performance and service life of the air compressor

[0004] Therefore, the air compressor is generally equipped with a drain valve, but although the existing drain valve can remove the moisture in the air compressor, it needs to be manually operated to drain water, which is always easy to be forgotten by people, so it is easy to retain a large amount of water in the air storage tank. Water, affecting the normal operation of the machine
