As shown in fig. 1 and 2, a buffer tube joint comprises a first connecting piece 1, a second connecting piece 2 and a compression screw sleeve 3, wherein a pipeline channel is arranged in the middle of the first connecting piece; the outer ends of the first connecting piece 1 and the second connecting piece 2 are fixedly connected with pipelines on two sides respectively, and the inner ends are mutually butted; the outer surface of the first connecting piece 1 is provided with a clamping table 11, the outer surface of the second connecting piece 2 is provided with an external thread 21, one end of the compression screw sleeve 3 is sleeved on the second connecting piece 2 through threads, and the other end of the compression screw sleeve is abutted against the clamping table 11; the inner surfaces of the first connecting piece 1 and the second connecting piece 2 close to the outer pipeline end are provided with a plurality of reinforcing ribs 4 protruding inwards; the inner surface of the abutting end of the first connecting piece 1 is a conical surface; the outer surface of the butt joint end of the second connecting piece 2 is a spherical surface; the outer surface of the abutting end of the second connecting piece 2 abuts against the inner surface of the abutting end of the first connecting piece 1 to form a ball cone seal.
When in installation, the first connecting piece 1 and the second connecting piece 2 are fixedly connected with two sides of management respectively, for example: welding integrally; the compression screw sleeve 3 is sleeved on the peripheries of the first connecting piece 1 and the second connecting piece 2, and is connected or fixed through threaded rotation, and when the connection is carried out, the inner conical surface of the first connecting piece 1 is mutually abutted with the outer spherical surface of the second connecting piece 2, so that sealing connection is formed, namely: and (5) sealing the ball cone. For easy installation, the outer end structures of the first connecting piece 1 and the second connecting piece 2 can be flexibly designed, for example, the outer end of the first connecting piece 1 is shown as an outer conical surface, and the outer end of the second connecting piece 2 is designed as a step shape. The strength of the pipe joint can be greatly enhanced by the design of the reinforcing ribs 4, particularly, the reinforcing ribs are designed at the position close to an external pipeline, and the fluid impact can be effectively buffered, so that the pipe joint is particularly suitable for being used in a flow change or vibration environment.
Preferably: the section of the reinforcing rib 4 is an arc-shaped curved surface; the arc heights of the reinforcing ribs 4 in the first connecting piece 1 and the second connecting piece 2 are sequentially increased from outside to inside, namely h1 is more than h2 and less than h3 and less than h4 and less than h5 in the figure; and each reinforcing rib 4 in the pipeline of the first connecting piece 1 or the second connecting piece 2 is sequentially connected to form a wavy slow-flow belt.
