Abstract
The utility model provides a compound slot pipe fitting of inside lining stainless steel, including outer slot malleable iron pipe fitting, the fixed body, stainless steel lining and terminal surface turn -ups layer, the stainless steel lining is fixed through the fixed body on the inner wall of outer slot malleable iron pipe fitting, terminal surface turn -ups layer sets up the tip of outer slot malleable iron pipe fitting, the tip on terminal surface turn -ups layer with the end fixing of stainless steel lining links to each other. Compound slot pipe fitting of inside lining stainless steel because the terminal surface is in the medium aquatic with the inner liner simultaneously, because there is the potential difference between the different materials, and constitutes galvanic corrosion, therefore leads to the pipe fitting to be corroded, and then pollute the technological problem of drinking water when it is connected in having solved prior art.
Description
Technical field
This utility model relates to a kind of groove pipe fitting, in particular it relates to a kind of inner liner stainless steel composite trench pipe fitting。
Background technology
Drink by the quality of water to improve, it is prevented that some the harmful elements caused due to the inwall of water long-term corrosion metal tube enter to be drunk with water, is detrimental to health, and inner liner stainless steel water delivery pipeline is widely used。At present, the pipe fitting that the pipeline of bore >=80mm connects perfect not, when pipe fitting adopts groove to be connected with pipe fitting or pipe fitting with pipeline, there is no inner liner stainless steel composite pipe rational in infrastructure, when adopting common pipe fitting to be attached, it is easy to cause the end face of pipeline to corrode, corrosion occurs, after pipe end corrosion, pollute and drink with water, thus causing that the sanitary condition of drinking water is defective。Or adopting the inner liner stainless steel groove pipe fitting of unreasonable structure, lining and groove pipe fitting do not fit tightly, and there is relatively larger gap between the two, after connection, water enters rustless steel and forms, with groove inner surface of pipe fitting, the galvanic corrosion layer corroded, and accelerates the corrosion of carbon steel, causes the leakage of pipeline。
Utility model content
This utility model is in order to solve inner liner stainless steel composite trench pipe fitting of the prior art when it connects, owing to end face and inner liner are simultaneously in WATER AS FLOW MEDIUM, because there is potential difference between different materials, and constitute galvanic corrosion, thus result in pipe fitting to be corroded, and then the technical barrier of polluted drinking water, it is provided that a kind of inner liner stainless steel composite trench pipe fitting。
For solving above-mentioned technical problem, this utility model provides a kind of inner liner stainless steel composite trench pipe fitting, outer layer groove malleable cast iron pipe fitting, fixed body, rustless steel lining and end face flange layer, described rustless steel lining is fixed on the inwall of described outer layer groove malleable cast iron pipe fitting by fixed body, described end face flange layer is arranged on the end of described outer layer groove malleable cast iron pipe fitting, and described end face flange layer is one-body molded with described rustless steel lining。
Further, the end of described fixed body flushes with the end of described outer layer groove malleable cast iron pipe fitting, and described end face flange layer is fixed on described fixed body end and outer layer groove malleable cast iron pipe fitting end。
Further, the external diameter of described end face flange layer is more than the internal diameter of described outer layer groove malleable cast iron pipe fitting, and less than the external diameter of described outer layer groove malleable cast iron pipe fitting。
Further, described fixed body is food stage PPR material。
Further, the material of described rustless steel lining is austenitic stainless steel or ferritic stainless steel。
Further, the material of described rustless steel lining is 0Cr18Ni9 stainless steel material。
The Advantageous Effects that this utility model reaches: this utility model provides a kind of inner liner stainless steel composite trench pipe fitting, by arranging and the integrated end face flange layer of rustless steel lining in the end of outer layer groove malleable cast iron pipe fitting, when achieving pipe fitting connection, WATER AS FLOW MEDIUM only contacts with rustless steel lining, thus ensure that in the middle part of pipe fitting process under arms generation galvanic corrosion, while extending pipe fitting service life, improve transfer efficiency, ensure that delivery safety, and then ensure that the sanitary index of water。This utility model is in installing and using process simultaneously, easy to assembly, it is easy to be dealt into installation requirement, has broad application prospects。
Accompanying drawing explanation
Fig. 1 this utility model structural representation。
Detailed description of the invention
In order to be able to the technique effect being better understood by technical characteristic of the present utility model, technology contents and reaching, now accompanying drawing of the present utility model is described in detail in conjunction with the embodiments。
Below in conjunction with drawings and Examples, this utility model patent is further illustrated。
As shown in Figure 1, this utility model provides a kind of inner liner stainless steel composite trench pipe fitting, outer layer groove malleable cast iron pipe fitting 1, fixed body 2, rustless steel lining 3 and end face flange layer 4, described rustless steel lining 3 is fixed on the inwall of described outer layer groove malleable cast iron pipe fitting 1 by fixed body 2, described end face flange layer 4 is arranged on the end of described outer layer groove malleable cast iron pipe fitting 1, and the end of the end of described end face flange layer 4 and described rustless steel lining 3 is fixedly linked。
The end of described fixed body 2 flushes with the end of described outer layer groove malleable cast iron pipe fitting 1, described end face flange layer 4 is fixed on described fixed body 2 end and outer layer groove malleable cast iron pipe fitting 1 end, the external diameter of described end face flange layer 4 is more than the internal diameter of described outer layer groove malleable cast iron pipe fitting 1, and less than the external diameter of described outer layer groove malleable cast iron pipe fitting 1, thus ensure that the fastness that end face flange layer 4 is fixing in outer layer groove malleable cast iron pipe fitting 1 end。
This utility model is in order to ensure the sanitary index of water, and material therefor all adopts food grade materials, if described fixed body 2 is food stage PPR material；The material of described rustless steel lining 3 is austenitic stainless steel or ferritic stainless steel, it is preferred to 0Cr18Ni9 stainless steel material。
Below disclose this utility model with preferred embodiment, so itself and be not used to restriction this utility model, all take equivalent replacement or technical scheme that the scheme of equivalent transformation obtains, all fall within protection domain of the present utility model。
