Abstract
The utility model relates to a hole expander for plastic pipe fitting. The hole expander comprises a drilling pipe, wherein a front center-positioning stop, a round cutter head and a rear hole-depth-positioning stop are arranged on the drilling pipe from front to back, the diameter of the rear hole-depth-positioning stop is greater than that of the round cutter head; and the diameter of the round cutter head is greater than that of the front center-positioning stop. The hole expander has the advantages of being convenient to maintain when the water leakage of a pipeline happens, so that the maintenance workload is reduced; and the maintenance cost is lowered.
Description
Technical field
The utility model relates to the maintenance tool of repairing plastic pipe fitting, particularly a kind of plastic pipe reamer.
Background technology
Existing reparation PP-R plastic tube installation method is that a water system is finished the unified bulge test in back, if do not weld in suppressing process, finds to leak, and will slice off entire PP-R plastic pipe (threeway or elbow).For example: an end of a PP-R plastic three-way leaks, and have to all slice off whole threeway with existing method.In addition, if in work progress the PP-R plastic pipe back of burn-oning is found that weldering is wrong, existing way is the PP-R plastic pipe to be sliced off again weld, and causes great waste.Find after particularly being delivered for use to leak, maintenance difficulty is bigger.Because the PP-R plastic tube does not have rigidity, generally all be to bury in the wall or underground, must all take out whole one or a string PP-R plastic tube if there is a place to leak, could repair the place that leaks.If threeway has been leaked in the middle of the comb, need slice off the threeway of leaking from the centre, the length of plastic tube has just shortened so, has dwindled the spacing of two adjacent taps or shower nozzle, has changed the pipe design size.
Summary of the invention
It is easy to maintenance when leaking that this practical technical problem that newly will solve provides a kind of pipe fitting, reduces maintenance load, reduces maintenance cost, do not change the plastic pipe reamer of pipe design size.
The plastic pipe reamer that the utility model relates to, has drilling rod 4, be provided with centralized positioning front 1, round cutterheads 2 and hole depth location backstop 3 on the drilling rod 4 from front to back, described hole depth is decided the diameter of hole backstop 3 greater than the diameter of round cutterheads 2, and the diameter of described round cutterheads 2 is greater than the diameter of centralized positioning front 1.
Described centralized positioning front 1, round cutterheads 2, hole depth location backstop 3 are one with drilling rod 4.
Described centralized positioning front 1 is pylon, and described hole depth is decided hole backstop 3 for discoid.
The utility model has the advantages that: when a certain end of connecting tube in the water system (threeway or elbow) leaks, as long as this end of maintenance, during operation plastic tube and pipe fitting junction are cut, then the drilling rod rear end is connected with electric hand drill, the drilling rod front end is inserted corresponding pipe fitting leak in the plastic tube of end, the centralized positioning front works the centralized positioning effect of finding accurately, the hole depth location backstop control reaming degree of depth, utilize cutter head that the weldment in the plastic tube port is left over part and polish off, welded tube connects again.Avoided prior art that whole pipe fitting is all downcut replacing, easy to maintenance, reduce maintenance load, reduce maintenance cost, do not change the pipe design size.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is operation chart of the present utility model;
Among the figure: centralized positioning front 1, round cutterheads 2, hole depth location backstop 3, drilling rod 4, plastic tube 5, weldment are left over part 6.
The specific embodiment
As shown in Figure 1, the utlity model has drilling rod 4, be provided with from front to back on the drilling rod 4 with it and be the centralized positioning front 1 of one, round cutterheads 2 and hole depth location backstop 3, the diameter of described hole depth location backstop 3 is greater than the diameter of round cutterheads 2, and the diameter of described round cutterheads 2 is greater than the diameter of centralized positioning front 1.Described centralized positioning front 1 is pylon, and described hole depth location backstop 3 is discoid.
As shown in Figure 2, if when finding that the tee pipe fitting end that has welded leaks, with the corresponding end junction cutting of leaking with tee pipe fitting of plastic tube 5, then drilling rod 4 rear ends are connected with electric hand drill, drilling rod 4 front ends are inserted corresponding tee pipe fitting leak in the plastic tube 5 of end, work the centralized positioning effect of finding accurately by centralized positioning front 1, by the hole depth location backstop 3 control reaming degree of depth, utilize cutter head 2 that the weldment in the plastic tube 5 is left over part 6 and polish off, welded tube connects again.
Claims (3)
1. plastic pipe reamer, has drilling rod, drilling rod is provided with centralized positioning front, round cutterheads and hole depth location backstop from front to back, and the diameter of described hole depth location backstop is greater than the diameter of round cutterheads, and the diameter of described round cutterheads is greater than the diameter of centralized positioning front.
2. plastic pipe reamer according to claim 1 is characterized in that: centralized positioning front, round cutterheads, hole depth location backstop are one with drilling rod (4).
3. plastic pipe reamer according to claim 1 and 2, it is characterized in that: described centralized positioning front is pylon, described hole depth location backstop is discoid.
