Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-5, a connecting device for compressed air pipelines comprises a main pipe 1, a connecting pipe 2 and a spacing column 3, wherein the main pipe 1 comprises a first pipe 12, a second pipe 11, a first pipe 12 and a second pipe 11 which are integrally formed, an internal channel of the second pipe 11 is communicated with an internal channel of the first pipe 12, the connecting pipe 2 is installed on the first pipe 12, the internal channel of the connecting pipe 2 is communicated with the internal channel of the first pipe 12, the spacing column 3 is fixedly installed on the internal channel of the first pipe 12, and a channel is arranged on the spacing column 3 and is respectively communicated with the internal channel of the connecting pipe 2, the internal channel of the first pipe 12 and the internal channel of the second pipe 11.

The number of the connecting pipes 2 is two, and the two connecting pipes 2 are respectively communicated with two ends of the No. one pipe 12.

The internal channels of the two connecting pipes 2 are truncated cone-shaped channels 4, the end face with the smallest cross section of the truncated cone-shaped channel 4 on one connecting pipe 2 is communicated with the internal channel at one end of the No. one pipe 12, and the end face with the largest cross section of the truncated cone-shaped channel 4 on the other connecting pipe 2 is communicated with the internal channel at one end of the No. one pipe 12.

The number of the second tubes 11 is at least two, and the tube diameter of the inner channel of the second tubes 11 is larger than that of the inner channel of the first tubes 12.

The inner channel on the limiting column 3 is a spiral channel 5, the depth of the spiral channel 5 is reduced from one end of the first tube 12 to the other end of the first tube 12, and the circular truncated cone-shaped channel 4 which is communicated with the inner channel at one end of the first tube 12 and has the largest cross section area is communicated with the spiral channel 5 with the deepest depth.

It should be noted that: the device enables the internal channel at the end with the minimum sectional area at the end part to be communicated with the pipe with the small pipe diameter and the internal channel at the end with the maximum sectional area at the end part to be communicated with the pipe with the large pipe diameter by the modes of flanges, bolts and the like, thereby realizing the communication between the pipe with the small pipe diameter and the pipe with the large pipe diameter.
