Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a PPR pipe butt joint hot-melt connection process, which can solve the problem that the joint is usually carried out manually. Since the pipe mouth is a transitional fit and the strength of the personnel is small, it is difficult to make a smooth joint. Reduce the difficulty of docking. It is inevitable that pe...

Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] Such as Figure 1 to Figure 7 As shown, a PPR pipe butt hot-melt connection process uses a clamping extrusion device, which includes a bottom frame 1, a driving device 2, two embedded frames 3, and two extrusion units 4 and measuring device 5, the specific process when using the above-mentioned clamping and extrusion device to carry out butt hot-melt connection of PPR pipes is as follows:

[0036] S1. Nozzle cleaning: clean the nozzles of the two PPR pipes to be connected;

[0037] S2, hot-melt treatment: hot-melt treatment is carried out on the nozzle after the step S1 is c...

Abstract

The invention provides a PPR pipe butt-joint hot melting connection process which is carried out by cooperation of a bottom frame, a driving device, two embedded frames, two extrusion units and a measuring device. By means of the PPR pipe butt-joint hot melting connection process, the problems that a manual butt joint mode is usually adopted, due to the fact that pipe openings are in transition fit during butt joint and the force of a person is small, smooth butt joint is difficult, in order to reduce the difficulty of butt joint, the person can hardly avoid rotary butt joint during butt joint, while rotary butt joint usually leads to the reduction of the tightness of a butt joint, consequently, the conditions of water leakage, air leakage and the like are caused, besides, when the butt joint is carried out, the insertion depth of the pipe openings cannot be seen, and when the depth is too shallow, the butt joint openings of two PPR pipes after the butt joint can be cracked in use.

Description

technical field [0001] The invention relates to the field of PPR pipe connection, in particular to a PPR pipe butt joint hot-melt connection process. Background technique [0002] Hot-melt is generally used as hot-melt connection. The principle of hot-melt connection is to put the nozzles of two PPR pipes close to the heating tool to heat the flat end faces until they melt. After removing the heating tool, tighten the two melted nozzles. Close together, keep the joints cool under the action of pressure, so that the two sections of pipelines are connected as a whole operation, the heat welding method improves the sealing of the joints, and avoids water leakage during use; [0003] However, some problems are often encountered when butt extruding two molten nozzles: [0004] 1. The docking is usually done manually. Due to the transitional fit and the small strength of the personnel when the nozzle is docked, it is difficult to dock smoothly. It often leads to a reduction in t...
