Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PPR pipe fittings, in particular to a PPR pipe fitting which is easy to disassemble and assemble. Background Art
[0002] PPR is the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipe. It adopts hot-melt welding, has special welding and cutting tools, and has high plasticity. The price is also very economical, with an additional insulation layer, better insulation performance, and a smooth pipe wall. It does not include joints with internal and external threads. It is generally used for embedded walls or deep well pre-buried pipes.
[0003] Existing PPR pipe connectors are generally set to a right-angle L-shape. This shape will cause greater resistance when water flows in the PPR pipe connector, causing the PPR pipe connector to shake. This may not only cause loosening and leakage at the connection between the PPR pipe connectors, but also cause a decrease in water flow in the PPR pipe connector, affecting users' water needs.
[0004] To this end, we propose a PPR pipe fitting that is easy to disassemble and assemble. Utility Model Content
[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a PPR pipe fitting which is easy to disassemble and assemble.

[0028] Embodiment 2: Based on Embodiment 1, Figure 2 As shown, a water inlet pipe 12 is fixedly installed on the lower end of the left side wall of the first arc transition pipe 11, and a water inlet interface 13 is provided on the left side wall of the water inlet pipe 12. By setting a first chamfer 17 and a second chamfer 18, the first chamfer 17 and the second chamfer 18 can respectively reduce the resistance of the water inlet pipe 12 and the water outlet pipe 15 when they are socketed with the PPR pipe, thereby facilitating the installation of the entire device.
[0029] Embodiment 3: Based on Embodiment 1 and Embodiment 2, Figure 3 As shown, a second arc transition pipe 14 is fixedly installed on the top of the connecting pipe 10, a water outlet pipe 15 is fixedly installed on the upper end of the front side of the second arc transition pipe 14, and a water outlet interface 16 is provided on the front side of the water outlet pipe 15. By arranging the connecting pipe 10, the first arc transition pipe 11 and the second arc transition pipe 14, the first arc transition pipe 11 and the second arc transition pipe 14 are connected and combined into an S shape through the connecting pipe 10, so that other PPR pipes can pass directly from under the first arc transition pipe 11 or the second arc transition pipe 14, so that the whole device has the same function as the bridge elbow, and the first arc transition pipe 11 and the second arc transition pipe 14 are connected and combined into an S shape through the connecting pipe 10, which has the effect of increasing height when standing up, so that it can effectively avoid obstacles when installed in a corner, simplifying the construction steps and improving work efficiency.

During the installation process, the existence of the first chamfer 17 and the second chamfer 18 makes the water inlet pipe 12 and the water outlet pipe 1 5 When inserting and socketing the PPR pipe, the resistance is reduced, which is convenient for the installation of the whole device. In addition, the arc design of the first arc transition pipe 11 and the second arc transition pipe 14 allows other PPR pipes to pass directly from below, playing the role of a bridge elbow.
