Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, a fire-resistant fire-retardant PE pipe, includes body 1 and screw thread ring 4, and the right side fixed mounting of body 1 has screw thread ring 4, and the outside of body 1 closely laminates has fire-retardant layer 101, and the inboard of fire-retardant layer 101 closely laminates middle part layer 2, and the inside of middle part layer 2 closely laminates inner tube 3, the left side fixedly connected with spring 5 of the 1 inner wall of body, the outside fixedly connected with thread groove 6 of spring 5.

Further, fire-retardant layer 101 is fire-retardant layer 101 of silicone rubber, is convenient for more when the body 1 outside is overheated or when contacting with the flame, and fire-retardant layer 101 can be effectively fire-retardant with the outside heat, and fire-resistant flame retardant property is better.

Furthermore, a proper amount of cooling liquid is injected into the middle layer 2, so that when the flame-retardant layer 101 is overheated, the cooling liquid of the middle layer 2 can absorb heat in the flame-retardant layer 101 to cool the flame-retardant layer 101, and the performance deterioration of the flame-retardant layer 101 caused by overheating is prevented.

Further, the threaded ring 4 is supporting setting with thread clamping groove 6 for the threaded ring 4 of body 1 can twist fast and fix in the thread clamping groove 6 of another body 1, realizes the fast assembly of two bodies 1, further improvement the equipment speed of device.
