Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to fig. 2-10, a connection structure of a memory titanium alloy pipe joint is provided, wherein the connection structure is a connection protrusion 1a which is arranged on the inner wall of a pipe joint 1 and can be embedded into the inner wall of a pipe body 2 to be connected, under the action of memory deformation of the pipe joint, the connection protrusion 1a is contracted by the inner wall of the pipe joint 1 and embedded into the outer wall of the pipe body 2 to be connected, an embedded groove (shown as 2a in fig. 4) is correspondingly formed in the outer wall of the pipe body 2, and under the action of fluid impact in the pipe body 2, the relative movement between the pipe body 2 and the pipe joint 1 can be effectively limited by the embedded positioning of the connection protrusion 1a and the embedded groove, so that the connection strength and the sealing performance of the pipe joint are improved.
As shown in fig. 2, the connecting protrusions 1a are preferably arranged at intervals on two sides of the inner wall of the pipe joint, so that the connecting protrusions can be connected with the pipe bodies 2 to be connected on two sides in an embedded manner, and embedded closed connection of the pipe joint 1 to the pipe bodies 2 on two sides is realized.
Specifically, as shown in fig. 2, the connecting protrusion 1a has a rectangular structure with a certain axial width, which is protruded from the inner wall of the pipe joint 1 toward the axial direction thereof. This structure makes the coupling projection 1a have a certain embedding width in the axial direction of the inner wall of the pipe joint 1 to resist the force of the end of the pipe body 2 being relatively moved with the pipe joint 1 by the impact of the fluid.
When the end of the pipe body 2 is impacted by a large fluid, the connection protrusion 1a is separated from the embedded groove of the outer wall of the pipe body 2 after the connection protrusion 1a is worn and deformed at the joint of the side wall of the connection protrusion 1a and the side wall of the pipe body 2, particularly at the corner of the connection protrusion 1a (shown as a position a in fig. 4), due to the impact force of the fluid, as shown in fig. 5-7, the limit protruding edges 1a1 are formed at the two ends of the connection protrusion 1a, which are close to one side edge of the pipe joint 1 in the axial direction, and extend obliquely towards the outer side direction of the axis of the pipe joint 1 and the axis combination of the two ends. The limit rib 1a1 can extend the corner of the connecting protrusion 1a further to the outside direction to resist and limit the abrasion degree of the corner of the embedded groove of the outer wall of the pipe body 2, so that the connecting protrusion 1a can be stably embedded into the embedded groove of the outer wall of the pipe body 2 and maintain the connection strength of the two.
Since the direction of the fluid in the pipe body is unidirectional, after the pipe end of the pipe body 2 is impacted by the flow of the fluid, the pipe end acts on one side of the connecting protrusion 1a, under the action of the acting force, the outer wall of the pipe joint 1 corresponding to the connecting protrusion 1a is stressed to generate cracks (shown in b in fig. 8), and then the pipe joint is broken, so that in order to solve the problem, a reinforcing structure corresponding to the connecting protrusion 1a is arranged on the outer wall of the pipe joint 1, as shown in fig. 9-10, the reinforcing structure is a reinforcing protrusion 1b convexly arranged on the outer wall of the pipe joint 1 corresponding to the connecting protrusion 1a, and the wall thickness of the pipe joint 1 at the part is integrally increased by the reinforcing protrusion 1b and the connecting protrusion 1a so as to resist the problem that the outer wall of the pipe joint 1 is cracked and broken due to the stress under the action of the axial tension of the pipe body 2, thereby improving the fluid impact strength of the pipe joint 1.
The principle of the utility model is as follows: the inner wall of the pipe joint 1 is provided with a connecting protrusion 1a which is embedded into the outer wall of the pipe body 2 to be connected, so that the relative connection positioning of the connecting protrusion and the pipe body is realized, and meanwhile, the corner of the connecting protrusion 1a is provided with a limit convex edge 1 so as to resist the abrasion of the connecting protrusion 1a caused by an embedded groove formed on the outer wall of the pipe body 2 and the problem that the pipe body is easy to separate from the pipe joint after the abrasion, thereby further improving the connection strength of the pipe joint. And the position of the outer wall of the pipe joint corresponding to the connecting bulge 1a is also provided with a reinforcing bulge 1b which is used for resisting the problem that the outer wall of the pipe joint 1 is cracked and broken due to stress under the action of the axial tension of the pipe body 2 of the connecting bulge 1a, so that the strength of the pipe joint 1 under the impact of fluid is improved.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. The present utility model is subject to various changes and modifications without departing from the spirit and scope thereof, and such changes and modifications fall within the scope of the utility model as hereinafter claimed.
