Embodiment Construction

[0021] The technical solutions of the present invention will be further illustrated and described below through specific embodiments in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a pipe connection structure includes a tubular joint 1 and a hose 2 set at one end of the tubular joint 1, wherein the material of the tubular joint 1 is light-transmitting PP, PE, POM or PA, and the hose 2 The material is PERT, PE, POM or PA with light-absorbing color (preferably black), and the tubular joint 1 and the hose 2 are fixedly connected by laser welding. The parameters of laser welding are: power 13-28W, speed 45-50rpm, preferably The power is 18W and the speed is 45rpm. The strength of the prepared pipe fitting connection structure can reach 500 psi when performing a burst pressure test.

[0023] In a preferred embodiment of the present invention, one end of the tubular joint 1 is provided with a stepped hole 10, and the stepped hole includes a small...

Abstract

The invention discloses a manufacturing method for a pipe fitting connecting structure. The pipe fitting connecting structure comprises a tubular connector and a hose which is arranged at one end of the tubular connector in a sleeving manner, wherein the material of the tubular connector is light-transmitting PP, PE, POM or PA; the material of the hose is PERT, PE, POM or PA with light absorption colours; the tubular connector is fixedly connected with the hose through laser welding; the laser welding parameters are that: the power is 13 to 28 W, and the rotating speed is 45 to 50 rpm. The pipe fitting connecting structure manufactured by the manufacturing method disclosed by the invention comprises the tubular connector and the hose which are tightly connected with each other through laser welding; the material of the tubular connector is PP, PE, POM or PA; the material of the hose is PERT, PE, POM or PA; the strength of the hose can reach 500 psi when a bursting pressure test is performed.

Description

technical field [0001] The invention specifically relates to a pipe fitting connection structure and a manufacturing method thereof. Background technique [0002] PERT is a non-cross-linked polyethylene pipe that can be used for hot water, and it is also a medium-density polyethylene pipe. It not only has the characteristics of high temperature resistance, but also has good flexibility, good pressure resistance, non-toxic, odorless, and pollution-free , low temperature resistance and other characteristics, very suitable for the material of water components. In addition, the water-passing components are changed from copper to plastic materials such as PERT, which greatly reduces the cost of materials and parts processing costs, and reduces the damage to the human body caused by heavy metals contained in copper-made water-passing components, thereby enhancing the market competitiveness of the product. [0003] CN103640212A discloses a laser welding process for water passing c...
