Abstract
The utility model discloses an improved polybutylene outer sleeve joint. The improved polybutylene outer sleeve joint comprises a polybutylene outer sleeve. A metal female connection jacket is embedded into the polybutylene outer sleeve, a ring groove is formed in the outer wall, corresponding to the metal female connection jacket, of the polybutylene outer sleeve, and a metal tightening ring is arranged in the ring groove. Thermal expansion deformation of the polybutylene outer sleeve can be effectively limited through the metal tightening ring of the improved polybutylene outer sleeve joint, it is guaranteed that the metal female connection jacket and the polybutylene outer sleeve cannot be separated from each other due to different expansion rates in the heating process, and water leakage hidden dangers are completely eradicated.
Description
Technical field
The utility model relates to pipe joint field, particularly a kind of improved type polybutylene outer sleeve joint.
Background technique
Widely used water tubular union is in polybutylene outer sleeve, to be provided with a metal internal thread pipe fitting in the market, as Chinese patent notice of authorization, CN201803038U discloses a kind of Polybutylene threaded pipe fitting, it comprises polybutylene outer tube and metal threaded inner sleeve, polybutylene outer tube comprises outer tube joint and overflow pipe two-part, the inwall of polybutylene outer tube is provided with screw thread, the screw thread of metal threaded inner sleeve has identical involute modulus with the screw thread of polybutylene outer tube wall, in metal threaded, be set in the end of polybutylene outer tube wall, two sections are threaded and are integrated.If there is flow of hot water mistake in pipeline, process is metal threaded inner sleeve so at first, and because heat dissipation metal is good, thermal coefficient of expansion is little, and simultaneously rigidity is stronger, so the tube wall of joint can not be out of shape easily, better tightness; But when temperature is higher, the polybutylene outer tube of this patent and metal threaded inner sleeve, because ratio of shrinkage swelling is inconsistent, easily cause polybutylene outer tube separated with metal threaded inner sleeve position, cause and leak.
Model utility content
The purpose of this utility model is for shortcomings and deficiencies of the prior art, and a kind of improved type polybutylene outer sleeve joint is provided, and this improved type polybutylene outer sleeve joint structure is stable, prevents that temperature overheating from causing pipe fitting to leak.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of improved type polybutylene outer sleeve joint, comprise polybutylene outer sleeve, in described polybutylene outer sleeve, be embedded with a metal internal thread connecting sleeve, it is characterized in that, on outer tube wall at described polybutylene outer sleeve corresponding to described metal internal thread connecting sleeve, offer an annular groove, in described annular groove, be provided with a metal fastening piece.
In a preferred embodiment of the present utility model, between the bottom outside of described metal internal thread connecting sleeve and described polybutylene outer sleeve inner tubal wall, be provided with seal ring.
Owing to having adopted technological scheme as above, metal fastening piece of the present utility model can effectively limit polybutylene outer sleeve heat expansion deformation, guarantee that metal internal thread connecting sleeve and polybutylene outer sleeve can be not different and separated because of expansivity when the heat, stop the hidden danger of leaking.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of embodiment's of the utility model sectional view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of improved type polybutylene outer sleeve joint shown in Figure 1, comprises polybutylene outer sleeve 100, is embedded with a metal internal thread connecting sleeve 200 in polybutylene outer sleeve 100.On outer tube wall 110 at polybutylene outer sleeve 100 corresponding to metal internal thread connecting sleeve 200, offer an annular groove 120, in annular groove 120, be provided with a metal fastening piece 130.Metal fastening piece 130 can effectively limit the 100 heat expansion deformation of polybutylene outer sleeve, guarantees that metal internal thread connecting sleeve 200 and polybutylene outer sleeve 100 can be not different and separated because of expansivity when the heat, stops the hidden danger of leaking.
In order further to improve sealing of the present utility model, between the bottom outside of metal internal thread connecting sleeve 200 and polybutylene outer sleeve 100 inner tubal walls, be provided with seal ring 300.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
