Abstract
The utility model discloses a water pipe connecting device, in particular to a water pipe joint having the advantages of ingenious and simple structure, good connecting leak tightness, good leak-roof effect and low cost. A polybutene wire internal thread pipe fitting comprises a polybutene outer thimble and a metal internal thread connecting sleeve, wherein, the metal internal thread connecting sleeve is positioned at the inner part of the polybutene outer thimble; the upper side of the inner part of the polybutene outer thimble is provided with an annular lug boss; threads are arranged in the annular lug boss; a containing hole is arranged below the lug boss; the metal internal thread connecting sleeve is arranged in the containing hole below the lug boss.
Description
Technical field
The utility model relates to a kind of water pipe and connects device, specifically is meant a kind of Poly D Ene Wire Screw Thread Tube.
Background technique
The water pipe link of existing market is considered from antirust and manufacture cost, mostly adopts to be provided with a metal internal thread connecting sleeve in the polybutylene outer sleeve, so both can reach metal high strength, can reduce cost again.As shown in Figure 1, its structure is that sleeve pipe 1 ' internal upper part joint is provided with metal threaded connecting sleeve 2 ', be provided with a circle groove 11 ' at metal threaded connecting sleeve 2 downsides, in groove 11 ', be provided with seal ring 3 ', this structure is comparatively complicated, and it is bigger to add the man-hour difficulty, and because the setting of seal ring 3 ', the water pipe footpath 4 ' of crossing of its inside is diminished, thereby water flow is diminished.What use because of its inner connecting sleeve again is metal (copper), and when connecting two water pipe links, two metal threaded connecting sleeve 2 ' sealings that are positioned at end face are just relatively poor, and the waterproof rubber need be twined in the contacting point, and easily leaks, and uses inconvenient.When flowing through hot water in the water pipe, because the polybutylene material on surface is inconsistent with inner metal contracts expansivity, metal threaded connecting sleeve comes off easily.So the applicant has created following new technological scheme.
The model utility content
The purpose of this utility model is to provide a kind of structure ingenious simple, connects good airproof performance, and leak preventing effect is good, and the low water pipe adapter of cost.
For achieving the above object, technical solution of the present utility model is:
A kind of Poly D Ene Wire Screw Thread Tube, comprise polybutylene outer sleeve and metal internal thread connecting sleeve, described metal internal thread connecting sleeve is positioned at polybutylene outer sleeve inside, polybutylene outer sleeve upper inside is established annular boss, establish screw thread in the annular boss, be provided with a receiving hole below boss, described metal internal thread connecting sleeve is arranged in the receiving hole of below of boss.
Described metal internal thread connecting sleeve is a Cuprum alloy internal thread connecting sleeve.
Surface, described metal internal thread connecting sleeve place is provided with boss or groove, and polybutylene outer sleeve and metal internal thread connecting sleeve adopt the method for molding and forming to be closely pressed together on together.
After adopting such scheme, because the utility model metal internal thread connecting sleeve is positioned at polybutylene outer sleeve inside, polybutylene outer sleeve upper inside is established annular boss, establish screw thread in the annular boss, below boss, be provided with a receiving hole, described metal internal thread connecting sleeve is arranged in the receiving hole of below of boss, and structure is ingenious simple.During use, because the internal thread connecting sleeve is arranged in the receiving hole, the annular boss of its top can be fixed the metal internal thread connecting sleeve, it can not come off or be shifted, annular boss on the polybutylene outer sleeve inside has elasticity, when two pipe fittings docks, still can guarantee the good airproof performance of its connection, and the utility model can increase the intensity of connection, antileaking because outer sleeve upper inside annular boss is provided with screw thread, safe in utilization, it has omitted seal ring again, the water pipe of crossing in the polybutylene outer sleeve is directly become greatly, thereby increased the throughput of flowing water.Be plastic cement owing to the internal thread connecting sleeve again, working life is longer, good airproof performance, and cost is low.

Fig. 2 the utility model stereo appearance figure;
Fig. 3 the utility model structure sectional view.
The figure number explanation:
1, polybutylene outer sleeve 2, metal internal thread connecting sleeve 11, annular boss
12, screw thread 13, receiving hole 3, mistake water pipe footpath
Embodiment
A kind of Poly D Ene Wire Screw Thread Tube, comprise polybutylene outer sleeve 1 and metal internal thread connecting sleeve 2, as shown in Figure 2, metal internal thread connecting sleeve 2 is positioned at polybutylene outer sleeve 1 inside, polybutylene outer sleeve 1 upper inside is established annular boss 11, establishes screw thread 12 in the annular boss 11, is provided with a receiving hole 13 below annular boss 11, as shown in Figure 3, metal internal thread connecting sleeve 2 is arranged in the receiving hole 13 of below of annular boss.
In the practical application, the metal internal thread connecting sleeve can be chosen Cuprum alloy, nickel alloy internal thread connecting sleeve.Surface, metal internal thread connecting sleeve place is provided with boss or groove, as have the annular boss or an annular groove of fluctuating, polybutylene outer sleeve and metal internal thread connecting sleeve adopt the method for molding and forming to be closely pressed together on together, and annular boss or annular groove play reinforces and prevent the effect that the internal thread connecting sleeve comes off.
The utility model is compared with traditional technology, has cancelled in the polybutylene overcoat being provided with seal ring, makes the water pipe of crossing of its inside directly become greatly, can increase the throughput of flowing water like this.The utility model structure is ingenious simple, and production and processing is easy to operate, use the internal thread adapter sleeve can increase by two connect metallic water pipe tightness, when two pipe fittings docked, the shrinkage unanimity can not leaked, good airproof performance, leak preventing effect is good.
It more than is preferred embodiment of the present utility model; all changes of doing according to technical solutions of the utility model; when the function that is produced does not exceed the scope of technical solutions of the utility model; all belong to protection domain of the present utility model, can be applicable to the three-port structure that water pipe connects as the technical solution of the utility model.
