Quick centering and melting device for PPR water feeding pipes

Abstract

The invention discloses a quick centering and melting device for PPR water feeding pipes. The device comprises a hot melting frame, a heat conducting head, a machine body, indicating lamps, a switch,movable foot supports and a power supply wire; the hot melting frame is horizontally fixed on the plate surface at the bottom of the heat conducting head; two indicating lamps are provided, and are arranged on one horizontal line with the switch on the left side; four movable foot supports are provided, and are engaged with nuts at the bottom of the machine body through external threads at the tops; the bottom of the heat conducting head is tightly bonded on the upper surface of the machine body; and the power supply wire penetrates through a wire clip on the right side of the machine body, and is fixedly welded with a circuit board inside. After improvement, the device melts pipes more tidily and quickly, and prevents the condition of bad sealing condition caused by deformation of the pipe walls in the heating process; and through synchronous heating of two ends, the engagement capacity of joints is higher, and meanwhile, the borne water pressure is higher.

Description

technical field [0001] The invention relates to a water supply device, in particular to a fast centering welding device for PPR water supply pipes. Background technique [0002] PPR pipe has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, long service life, etc. , during the installation process, first put the inner wall of the butt joint and the outer wall of the water pipe into the mold for hot melting by hand. If the hand does not control the time when holding it, it is easy to deform the hot melting surface of the pipe wall. Due to the pressure of the water supply pipe Once the water pressure is high, once deformation occurs and the seal is not good, there will be bursts and leaks over time, and during the process of squeezing hard during welding, the arm will shake during the process of force, which will lead to bendi...
