Abstract
The utility model relates to a PP-R (Polypropylene) water supply pipe material combination which comprises a PP-R water pipe and a joint matched with the PP-R water pipe, wherein the PP-R water pipe comprises a polypropylene pipe body, and a metal layer is arranged on the inner surface of the polypropylene pipe body; two connectors are arranged on the joint, and a seal ring is embedded in the inner wall of each connector; and the seal rings are abutted against on the outer surface of the PP-R water pipe. In the PP-R water supply pipe material combination, tight fit between the PP-R water pipe and the joint are ensured, and leakage is not easy to occur; and the PP-R water pipe has large structural strength and is not easy to crack and break.
Description
[technical field]
The utility model relates to a kind of pipeline combination, is specifically related to a kind of PP-R pipe material for water supply combination, belongs to the pipe technology field.
[background technique]
PP-R is to being three type PA tubes again, and it has many characteristics such as in light weight, corrosion-resistant, non-scaling, long service life, simultaneously, and because of the higher preferred material that becomes the house ornamentation water pipe of its price ratio.
Though the PP-R pipe has above-mentioned advantage, this is not that the PPR water pipe is not have defective.Usually adopt hot melt to be connected such as, PP-R pipe with joint, cause leakage easily like this; Simultaneously, the anti-pressure ability of PP-R pipe is relatively poor, when its suffered pressure is big, causes tube wall cracking, breakage easily.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved PP-R pipe material for water supply combination that has is provided, to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide a kind of structural strength high and antileakaging PP-R pipe material for water supply combination.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: a kind of PP-R pipe material for water supply combination, and it comprises PP-R water pipe and the joint that matches with the PP-R water pipe; Wherein, said PP-R water pipe comprises a polypropylene body, is provided with a metal layer in the internal surface of said polypropylene body; Said joint is provided with two interfaces, on the inwall of each interface, is embedded with a seal ring; Said seal ring is connected on the outer surface of PP-R water pipe.
The PP-R pipe material for water supply combination of the utility model further is set to: said joint is 90 ° of bendings.
The PP-R pipe material for water supply combination of the utility model also is set to: said metal layer is a stainless steel lining.
Compared with prior art, the utlity model has following beneficial effect: the combination of the PP-R pipe material for water supply of the utility model is through being provided with seal ring, thereby guaranteed closely cooperating of PP-R water pipe and joint, is difficult for leakage; And this PP-R water pipe structure intensity is big, is difficult for taking place cracking and damaged.
[description of drawings]
Fig. 1 is the sectional drawing of the PP-R pipe material for water supply combination of the utility model.
[embodiment]
See also shown in the Figure of description 1, the utility model is the combination of a kind of PP-R pipe material for water supply, and it is connected to form through hot melt by PP-R water pipe 1 and with joint 2 two-part that PP-R water pipe 1 matches.
Wherein, said PP-R water pipe 1 comprises a polypropylene body 11, is provided with a metal layer 12 in the internal surface of said polypropylene body 11, and this metal layer 12 is a stainless steel lining.Through said metal layer 12 is set, thereby can improve the structural strength of this PP-R water pipe 1 greatly, make that the bearing capacity of this PP-R water pipe 1 is strong and be difficult for taking place cracking and damaged.
Said joint 2 is 90 ° of bendings, which is provided with two interfaces 21.On the inwall of each interface 21, be embedded with a seal ring 22.Said seal ring 22 is connected on the outer surface of PP-R water pipe 1.
The combination of the PP-R pipe material for water supply of the utility model is through being provided with seal ring 22 in joint 2, thereby guaranteed closely cooperating of PP-R water pipe 1 and joint 2, makes it be difficult for leaking.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
