Embodiment 1

[0028] like figure 1 and figure 2 As shown, the crimping joint includes a straight-through joint body 1 made of pipe material (specifically, carbon steel pipe). The connecting section 1b of the connecting section 1a has a protruding ring 1a1 at the end of the crimping section 1a, and a groove 1a2 is provided on the inner side of the crimping section 1a corresponding to the position of the protruding ring 1a1, and the groove 1a2 is used to place a sealing ring. Insert the thin-walled stainless steel pipe to be connected into the crimping section 1a, the sealing ring and the outer wall of the thin-walled stainless steel tube are pressed against to form a seal, and then clamped on the outside of the crimping section 1a with a crimping tool, so that the crimping section 1a and The thin-walled stainless steel tubes are simultaneously deformed inwards to hold them together. Further, the connecting section 1b includes a transition part 1b1 and a connecting part 1b2 sequentially al...

Embodiment 2

[0034] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the end of the connecting portion 1b2 is a constricted portion that shrinks inward to form a tapered portion, and the thread is arranged on the outside of the connecting portion 1b2 That is the external thread.

Abstract

The invention provides a clamping and pressing connector, and belongs to the technical field of pipelines. The problem that the use reliability is insufficient is solved. The clamping and pressing connector comprises a straight-through type connector body made of a pipe, the connector body is sequentially provided with a clamping and pressing section and a connecting section integrally and fixedly connected with the clamping and pressing section in the axial direction of the connector body, the connecting section sequentially comprises a transition portion and a connecting portion in the axial direction of the connector body, the transition portion is extruded and contracted in the direction away from the clamping and pressing section from the pipe to be in a conical shape, the connecting portion is extruded from one end of the pipe from outside to inside to form a cylinder with the outer diameter equal to the minimum outer diameter of the transition portion and the wall thickness increased, and the connecting portion is provided with threads. The clamping and pressing connector has the advantages of being high in use reliability, simple in structure, beneficial to batch production of enterprises and the like.

Description

technical field [0001] The invention belongs to the technical field of pipelines and relates to a compression joint. Background technique [0002] In some existing pipeline systems, such as fire-fighting systems or gas systems, compression joints are gradually used for connection. The traditional compression joint structure is such as the compression type stainless steel equal-diameter butt joint disclosed in the patent application number 201520422159.2. It includes a joint body arranged in a straight line. The joint body includes a first insertion pipe, an intermediate connecting pipe and a second insertion pipe. The first insertion pipe and the second insertion pipe communicate with each other through the intermediate connection pipe. The first insertion pipe and the second insertion pipe The inner diameters of the connecting pipes are the same, the inner diameter of the intermediate connecting pipe is smaller than the inner diameters of the first connecting pipe and the s...
