Abstract

The utility model relates to a pipe fitting used for the installation of a water supply pipe, in particular to a rapid self-fused junction plastic pipe ferrule. The ferrule body of the rapid self-fused junction plastic pipe ferrule presents as a pipe nipple. The inner wall of the ferrule body is embedded with a helical electrothermal wire wreathing the ferrule body. The terminals for power supplies of the electrothermal wire is led out by the two ends of the ferrule body. The rapid self-fused junction plastic pipe ferrule is sheathed on the interface of two butted pipes when being used, the rapid self-fused junction plastic pipe ferrule and the interface of the two pipes are quickly melted and combined together after ohmic heating, and the thickness of the pipe wall of the interface is increased. The rapid self-fused junction plastic pipe ferrule can be matched with the plastic pipes of domestic country standard and domestic enterprise standard, and the utilization rate of the pressure of the pipes of the same mode is improved by 1.2 to 1.5 times. The rapid self-fused junction plastic pipe ferrule has the advantages of convenient use, rapid self-fused junction, low technical requirement, etc.

Description

Fast from fusion knot plastics pipe collar

Technical field:

The utility model relates to the pipe fitting that uses in the supply channel installation, and is particularly a kind of fast from fusion knot plastics pipe collar.

Background technique:

At present in water supply project, use plastic tube to substitute the steel tubular goods of anti-corrosive properties difference in a large number, yet on plastic tube uses, the disadvantage that but exists interface pressure to reduce, its reason is: adopt a mouth of pipe heating, the direct insertion of another mouth of pipe is heated the mouth of pipe and cools off fixing socket joint docking mode again, owing to be heated the impaired pressure-bearing that reduced of mouth of pipe heating, therefore the pressure of whole supply channel must be reduced to the maximum pressure-bearing limit of interface; Adopt the mode of heating butt welding machine butt welding still to have above-mentioned disadvantage, this heating butt welding machine is carrying and is using the problem that all has inconvenience simultaneously.

Summary of the invention:

Goal of the invention of the present utility model is intended to solve tubing and does not reach the problem of the various unnecessary losses that cause owing to interface pressure in water supply project, and provides a kind of fast from fusion knot plastics pipe collar.

The technological scheme that realizes the foregoing invention purpose is: the hoop body of this plastics pipe collar is the pipe nipple shape, and the hoop body inwall embeds the spiral electric heating wire that has around hoop body, and the power supply terminal of this electric heating wire is drawn by the hoop body two ends.During use, this pipe collar is sleeved on two tubing jointings of butt joint, the power supply terminal of electric heating wire is connected to the Electric heating appliance with digital display timing, pressure regulation, heating automatic control function, the energising heating, make the rapid melted join of this pipe collar inner wall section and jointing two outer pipe walls part together, increased the jointing pipe thickness accordingly.

According to technique scheme implement fast from fusion knot plastics pipe collar can with domestic each GB and the supporting use of enterprise's mark plastic tube, the pressure utilization ratio rising 1.2-1.5 that can make equal model tubing is doubly; This pipe collar is easy to use, and fast from fusion knot speed, technical requirements is low, is assigned in special-purpose Portable Automatic control butt welding machine, and is then more convenient to operate.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a user mode schematic representation of the present utility model.

Embodiment:

Below in conjunction with drawings and Examples in detail the utility model is described in detail.This embodiment is described to tie the plastics pipe collar by hoop body 1 from fusion fast, electric heating wire 2, power supply terminal 4 is formed, this hoop body 1 is the pipe nipple shape, promptly similar to the pipe nipple in the common iron pipe fitting, its inwall embeds the spiral electric heating wire 2 that has around hoop body 1, the power supply terminal 3 of this electric heating wire 2 is drawn by hoop body 1 two ends, during use, this pipe collar is sleeved on the tubing 4 of butt joint and the jointing of tubing 5, power supply terminal 3 is connected to the power output end of automatic control butt welding machine, the energising heating, can make hoop body 1 inner wall section and jointing two tubing 4, the rapid melted join of 5 outer wall sections is integral, increased the thickness of this jointing tube wall accordingly, so the intensity of this jointing improves greatly.

Claims

1, a kind ofly comprise pipe nipple shape hoop body fast from fusion knot plastics pipe collar, it is characterized in that the spiral electric heating wire that this hoop body inwall embeds to be had around hoop body, the power supply terminal of this electric heating wire is drawn by the hoop body two ends.
