Quick connector of air energy storage pipeline

Technical Field

The utility model relates to the field of gas transmission, in particular to a quick connector of an air energy storage pipeline.

Background

The gas pipe path for conveying gas plays an important role in life production as a basic conveying component. The improvement of the design of the air pipe and the air path plays an important role in the development of the transmission in China, the use of the straight air pipe and the air path in each factory is quite popular, however, the influence on the air pressure in the air pipe and the air path is large in transmission at present, the air path design is dead, and the air tightness of the connecting part of the pipeline is still to be improved. The conventional pipeline connection mode has the respective defects of threaded connection, welding, connector connection, clamping sleeve type joint connection and the like, and cannot simultaneously meet the requirements of simple structure, high pressure resistance, corrosion resistance, long service life, detachability and the like, namely, the pipeline connection mode is not suitable for air energy storage pipeline connection.

Threaded connections commonly used in the market have low bearing pressure and are prone to decay and leakage at the threads. Welding at the joint results in welding defects and both ends are not detachable. The pipe connector is relatively complex in structure. The standard of the domestic cutting sleeve type connector still has defects and cannot bear high pressure. To avoid these drawbacks, the present utility model makes changes in the pipe joint.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provide a quick connector of an air energy storage pipeline, which has the advantage that the influence on the air pressure in an air pipe during gas transmission is reduced as much as possible.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the quick connector comprises a front connector and a rear connector, wherein the front connector is provided with a connector seat, the outer wall of the connector seat is provided with a limit strip, and the interior of the connector seat is a cavity for placing a pipeline; the rear connector is internally provided with an inserting cavity for inserting the inserting seat, and the inner wall of the inserting cavity is provided with a limiting groove matched with the limiting strip; the tail end of the rear joint is also provided with a duct for placing a pipeline, wherein after the front joint is connected with the rear joint in a plugging manner, the pipeline connected with the front joint is in butt joint with the pipeline connected with the rear joint.

The top of the plug seat of the front connector is provided with a fixed seat in an outward extending mode, and the periphery of the fixed seat is provided with a front connecting part; the top of the rear joint outwards extends to be provided with a rear connecting part, wherein after the front joint is connected with the rear joint in a plugging mode, the front connecting part and the rear connecting part are opposite and are both provided with screw holes, so that the front joint and the rear joint are connected in a screwed mode through screw nuts.

And a sealing layer is arranged at the joint of the front joint and the rear joint.

The quick connector is integrally made of aluminum alloy.

Compared with the prior art, the technical scheme of the utility model has the beneficial effects that:

the utility model increases the air tightness of the pipeline at the connecting part of the air pipe. The screw connection commonly used in the market has lower bearing pressure, and the screw position is easy to rot and leak, while the strength of the utility model is higher, and the screw connection is not in contact with the gas in the pipe, so that the screw connection is not easy to leak and rot. Compared with welding, the utility model avoids welding defects caused by welding of a plurality of joints, and the two ends of the pipeline are still detachable. The utility model is smaller and simpler than a pipe connector. The standard of the domestic cutting sleeve type connector still has defects, and cannot bear high pressure, and the utility model can bear a higher-pressure environment.
