Abstract
The utility model relate to an inserting structure of a hot melt type pipe connector and a PPR (Pentatricopeptide Repeats), which comprises the hot melt type pipe connector and the PPR pipe, wherein the inserting openings of the hot melt type pipe connector are respectively provided with an inner wall with a diameter which is gradually reduced from a port to the inner side of the pipe connector, and the PPR pipe is also provided with a pipe end which is fit with the shape of the inner wall of the corresponding inserting opening. In the utility model, as the inserting openings of the hot melt type pipe connector are respectively provided with the inner walls with gradually-reduced diameters, the contact surface of the inserting opening of the pipe connector and the pipe end of the PPR pipe is increased, further, the connection strength is improved, and simultaneously, the defect that in the existing hot melt type pipe connector, the melting material is extruded in advance so that the melting material is not uniformly distributed, the melting material at the root of the inserting opening is little can be avoided. According to the inserting structure, after hot melting, leakage phenomena are remarkably reduced, and the hot melting at the contact part of the inserting opening is more complete and firmer. The inserting structure disclosed by the utility model has the advantages of simple structure and simple construction process.
Description
Technical field
The utility model belongs to tube connection piece, particularly relates to the plug in structure of a kind of heat molten type pipe connector and PPR pipe.
Background technique
The chemical name of PPR (pentatricopeptide repeats) pipe is three type PA tubes, is to adopt gas-phase copolymerization technology to make 5% left and right sides PE even pipeline material of new generation of polymerization (random copolymerization) randomly in the molecular chain of PP.It has good shock resistance, creep-resistant property and excellent decay resistance, is insoluble to any known solvent under the normal temperature, and its purposes is very extensive.
The heat molten type pipe connector is the indispensable pipe joint of Using P PR pipe, and the heat molten type pipe connector comprises pipe collar, bent angle pipe collar, reducer union, threeway and the multiple-pass joint (please replenish or or corrigendum) etc. that are commonly called as, and its material is identical with the PPR pipe.
Existing heat molten type pipe connector is provided with PPR manages the plug-in mounting mouth that cylindrical pipe end shape is identical, diameter is almost equal, and PPR manages cylindrical pipe end and engages the after heat blow with this plug-in mounting mouth calmly.
Above-mentioned PPR manages cylindrical pipe end and heat molten type pipe connector plug-in mounting mouth plug-in mounting structure and has the not enough and seepage phenomenon of join strength behind the hot melt; Through dissect finding that its reason is that the plug-in mounting mouth is inhomogeneous with the axial distribution of PPR pipe cylindrical tube end in contact partial melting material, i.e. the molten material of extruding the more and plug-in mounting mouth root of molten material of the outer bead accumulation of plug-in mounting mouth seldom due to.
Summary of the invention
The purpose of the utility model is in order effectively to solve the technical problem of the not enough and seepage phenomenon of join strength behind existing heat molten type pipe connector and the PPR pipe hot melt, and proposes the plug in structure that a kind of heat molten type pipe connector and PPR manage.
The utility model is taked following technological scheme for realizing above-mentioned purpose: this plug in structure comprises heat molten type pipe connector and PPR pipe; Characteristic is; Each plug-in mounting mouth of said heat molten type pipe connector is respectively equipped with from port to the pipe connector inboard inwall of undergauge gradually, and said PPR pipe is provided with respectively the pipe end that matches with pairing plug-in mounting mouth inner wall shape.
The utility model can also be taked following technical measures:
Each plug-in mounting mouth of said heat molten type pipe connector from port to the pipe connector inboard gradually its longitudinal section of inwall of undergauge be taper type, said PPR pipe is provided with the pipe end that matches with plug-in mounting mouth taper type inwall.
Each plug-in mounting mouth of said heat molten type pipe connector from port to the pipe connector inboard gradually the outer contour of its longitudinal section of inwall of undergauge be polyline shaped, the pipe end shape of said PPR pipe matches with it.
Each plug-in mounting mouth of said heat molten type pipe connector from port to the pipe connector inboard gradually the outer contour of its longitudinal section of inwall of undergauge be arc shaped, the pipe end shape of said PPR pipe matches with it.
The beneficial effect and the advantage of the utility model are: the inwall of the undergauge gradually that the heat molten type pipe connector plug-in mounting mouth of this plug in structure is set, increased the area of contact that heat molten type pipe connector plug-in mounting mouth and PPR manage pipe end, and help the raising of join strength.Can also avoid extruding too early of molten material simultaneously and overcome the inhomogeneous and plug-in mounting mouth root molten material defective seldom of existing heat molten type pipe connector molten material axial distribution.This plug in structure has obviously reduced the seepage phenomenon behind hot melt, also make plug-in mounting mouth contacting part hot melt more fully, firmly.According to statistics, the PPR plumber journey of trial edition plug in structure has reduced over half because of interface seepage and the relatively poor rework rate of join strength.The utlity model has the simply outstanding advantage of structure and construction process.
