Description
Technical field
It the utility model is related to a kind of crossover sub that can be realized different pipe fittings and be welded to each other installation.
Background technology
People's living standard is gradually stepped up at present, and family expenses finishing material is more and more, and selection of the user to finishing material is got over
It is more accurate to come, and different equipment selects different finishing materials sometimes.The pipe fitting used in outdoor and some floor heatings is PPR at present
It is in the majority with PE, and indoor pipe fitting material selection PE-RT and PB are in the majority, the pipe fitting of different materials is run into when finishing to be needed to dock peace
During dress, it is necessary to it is a kind of can be with the crossover sub of welded and installed according to different tube materials.
Utility model content
For problems of the prior art, the purpose of this utility model is that different pipe fittings can be realized by providing one kind
It is welded to each other the technical scheme of the crossover sub of installation.
A kind of described crossover sub that can be realized different pipe fittings and be welded to each other installation, it is characterised in that including copper piece and
First joint and the second joint at copper piece both ends are arranged on, the first joint and the second joint use PE-RT, PB, PE, PPR tetra-
One kind in kind material, the first joint and the second joint and copper piece injection molding；The copper piece is by outer ring, inner ring and dowel group
Into copper piece is centered on dowel, two-end structure is symmetrical arranged, and the outer wall of outer ring is provided with the first dovetail groove, the inwall of outer ring
Second dovetail groove is set, and the inwall of outer ring and the junction of dowel set the first groove, and the outer wall of inner ring is connected with dowel
Place sets the second groove；First joint and the second joint, which are molded and rabbeted with copper piece, is arranged on the first dovetail groove, the second swallow
In stern notch, the first groove and the second groove.
A kind of described crossover sub that can be realized different pipe fittings and be welded to each other installation, it is characterised in that the inner ring length
Length of the degree less than outer ring.
Described a kind of crossover sub that can be realized different pipe fittings and be welded to each other installation, it is characterised in that described first connects
Head and the second joint cladding are arranged on outside first dovetail groove.
Described a kind of crossover sub that can be realized different pipe fittings and be welded to each other installation, it is characterised in that described first connects
Head and the second joint are coaxially disposed with copper piece.
The utility model be it is a kind of can according to different tube materials can welded and installed crossover sub, the conversion connects
The joint at the both ends of head can be any combination of tetra- kinds of materials of PE-RT, PB, PE, PPR.In order to ensure copper piece and plastic joint
Connection sealing, copper piece inner side and outer side both increases dovetail groove, ensure crossover sub it is water-tight in actual use and
Sealing, the pipe fitting that user can dock according to actual installation select the crossover sub of respective material.
The utility model solves the Welding Problems during pipe fitting abutting joint of different materials, achieves identical material
Welding, improves welding quality.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：1- copper piece, the joints of 2- first, the joints of 3- second, 4- outer rings, 5- inner rings, 6- dowels, the dovetails of 7- first
Groove, the dovetail grooves of 8- second, the grooves of 9- first, the grooves of 10- second.
Embodiment
With reference to Figure of description, the utility model is described in further detail：
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by accompanying drawing and implementing
Example, the utility model is further elaborated.However, it should be understood that specific embodiment described herein only to
The utility model is explained, is not limited to the scope of the utility model.In addition, in the following description, eliminate to known knot
The description of structure and technology, to avoid unnecessarily obscuring concept of the present utility model.
A kind of crossover sub that can be realized different pipe fittings and be welded to each other installation, including copper piece 1 and it is arranged on copper piece both ends
The first joint 2 and the second joint 3, the first joint 2 and the second joint 3 are used in tetra- kinds of materials of PE-RT, PB, PE, PPR
One kind, it can be selected according to the pipe fitting to be connected, the first joint 2 and the second joint 3 and the injection molding of copper piece 1.Copper piece 1 by
Outer ring 4, inner ring 5 and dowel 6 are formed, and copper piece is centered on dowel, two-end structure is symmetrical arranged, and the outer wall of outer ring 1 is set
There is the first dovetail groove 7, the inwall of outer ring sets the second dovetail groove 8, and the inwall of outer ring and the junction of dowel set first recessed
Groove 9, outer wall and the dowel junction of inner ring set the second groove 10, and the first joint and the second joint are molded and rabbeted with copper piece
It is arranged in the first dovetail groove, the second dovetail groove, the first groove and the second groove.
Specifically, inner ring length is less than the length of outer ring, and the first joint and the second joint cladding are arranged on first after injection
The outside of dovetail groove, and the first joint and the second joint are coaxially disposed with copper piece.
The dovetail groove that the outer wall of copper piece outer ring is set is to combine plastic cooling meat, so sealing effectiveness can be more preferable, outer ring
Inwall set dovetail groove be in order to prevent shrink after product gap, plastic cooling be to middle shrinkage, i.e., outer ring outer wall
It is to hold tightly, outer ring inwall is to prevent there is gap after shrinking, so can block material with dovetail groove.
The utility model embodiment provides the problem of a kind of pipe fitting to different materials carries out abutting joint, achieves phase
The tube material connected as needed with the welding of material, during actual use, selects corresponding crossover sub so that pipe fitting and connects
One head material of head is identical, it is achieved thereby that connection between different materials pipe fitting and excessively.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
