Abstract
The utility model discloses a connecting part for metal tap-water pipe; screw thread is arranged on the inner wall which is close to the connecting port; except for the screw thread, a plastic layer covers the other inner wall, said plastic layer is also covered with a stainless steel layer. After the above said structure is adopted, except for the screw thread, said plastic layer covers the inner wall and is also covered with a stainless steel layer, which solves the problem that rust is produced on the inner wall of the connecting part at one side, the effect upon water is equal to stainless steel connecting part; at the other side, because a plastic layer is covered on the inner wall except for the screw thread and the thickness is equal to matched water pipe thickness, the end part of tap-water pipe rightly sticks to the end surface of the plastic layer, which solves the rust problem of the end part of the tap-water pipe.
Description
Technical field
The utility model relates to a kind of pipe coupling, the link of a kind of metal running water pipe of more specifically saying so.
Background technique
Traditional metal running water pipe is generally galvanized pipe, is carbon steel tube, it has characteristics such as intensity height, cost be low, but, long-term use makes its inwall corrosion easily, the joint of water pipe particularly, when mounted, the end face of water pipe and screw thread place zinc coat are destroyed, tend in the water during use contain rust water, influenced health.Therefore, also adopt TP2 copper pipe and Stainless Steel Tube to make running water pipe at present, but play the price noble quality, and intensity is not as galvanized pipe.For this reason, the applicant applied for one " stainless steel composite running water pipe " (ZL:CN02234361X) in 2002, by the interior wall liner last layer stainless steel at galvanized pipe, had solved the iron rust problem of running water pipe.But the iron rust problem of its inner nosepiece wall and water pipe end still can not get solving.
The model utility content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of difficult metal running water pipe link that produces iron rust of inner nosepiece wall and water pipe end that solves.
For addressing the above problem, the utility model has adopted following technological scheme: a kind of link of metal running water pipe, be provided with screw thread at it near on the inwall of connection port, on the inwall except that screw thread, be covered with one deck plastic layer, on described plastic layer, also be covered with one deck stainless steel lining.The material of described plastic layer can be a polyvinylfluoride.The thickness of described plastic layer is identical with the water pipe thickness that is mated.Its described link can be two logical or threeways or four-way or curved connect etc.
Adopted said structure, be covered with plastic layer on the inwall except that screw thread, and also be covered with one deck stainless steel lining on described plastic layer, solved the problem that the link inwall produces iron rust on the one hand, its influence to water is equivalent to stainless steel adapting piece; On the other hand, owing on the inwall except that screw thread, be covered with one deck plastic layer, and its thickness is identical with the water pipe thickness that is mated, and like this, the end of running water pipe just in time is adjacent on the end face of plastic layer, has solved the iron rust problem of water pipe end.
Description of drawings
Fig. 1 is the structural representation that the link of metal running water pipe of the present utility model connects.
Among the figure: 1-connection port, 2-screw thread, the 3-inwall except that screw thread, 4-plastic layer, 5-stainless steel lining, the end face of 6-plastic layer.
Embodiment
The link of the metal running water pipe of present embodiment is two logical, can certainly be threeway or four-way or curved connect etc. because its structure is identical, therefore only with two logical be example.
As shown in Figure 1, the link of metal running water pipe of the present utility model is provided with screw thread 2 at it near on the inwall of connection port 1, on the inwall except that screw thread, be covered with one deck plastic layer 4, the material of described plastic layer 4 can be a ldpe resin, can certainly substitute with other plastics that can reach sanitary index.The thickness of described plastic layer 4 is roughly the same with the water pipe thickness that is mated, and like this, the end of running water pipe just in time is adjacent on the end face 6 of plastic layer during installation, has solved the iron rust problem of water pipe end.On described plastic layer 4, also be covered with one deck stainless steel lining 5, solve the problem that inner nosepiece wall produces iron rust.
Claims (4)
1, a kind of link of metal running water pipe, be provided with screw thread (2) at it near on the inwall of connection port (1), it is characterized in that being covered with one deck plastic layer (4) on the inwall (3) except that screw thread, on described plastic layer (4), also be covered with one deck stainless steel lining (5).
2, metal running water pipe according to claim 1 is external, it is characterized in that the material of described plastic layer (4) is a ldpe resin.
3, metal running water pipe according to claim 1 and 2 is external, it is characterized in that the thickness of described plastic layer (4) is roughly the same with the water pipe thickness that is mated.
4, metal running water pipe according to claim 1 is external, it is characterized in that described link is two logical or threeway or four-ways.
