Abstract
The utility model discloses a steel plastic conversion connector. The steel plastic conversion connector comprises a plastic pipe fitting (1) and a metal pipe fitting (2). The metal pipe fitting (2) is sleeved with the plastic pipe fitting (1), a compressing piece (3) compresses the joint of the plastic pipe fitting (1) and the metal pipe fitting (2), a reversing structure (4) and sealing rings (5) are arranged at the joint of the plastic pipe fitting (1) and the metal pipe fitting (2), a waterproof sleeve (2.1) is arranged on the outer wall of the metal pipe fitting (2), the end portion of the plastic pipe fitting (1) abuts against the waterproof sleeve (2.1), the height of the waterproof sleeve (2.1) is larger than the height of the compressing piece (3), and the two sealing rings (5) are arranged at the joint of the plastic pipe fitting (1) and the metal pipe fitting (2). The steel plastic conversion connector can be prevented from making direct contact with the ground.
Description
Technical field
The utility model relates to a kind of pipeline connecting fittings, relates to or rather a kind of pipe connector lug for the conveying of the fluids such as combustion gas, liquid.
Background technique
In the fluid-transporting tubing such as combustion gas field, pipeline commonly used is generally metallic conduit and the polyvinyl plastic pipelines such as steel pipe, and wherein metallic conduit is generally used for the Intermediate High Pressure fluid delivery system, and it is main that plastic pipe generally is used for low pressure.In addition, for the sake of security, national correlation engineering regulation and stipulation, plastic pipe does not allow directly to enter the end of pipeline, and namely the user's is indoor.Therefore, to the low pressure pipeline transition, and plastic pipe needs to adopt steel mould crossover sub when registering one's residence from the garden pipe usually at high pressure pipe line.Steel is moulded the crossover sub majority and is embedded in the underground of humidity, and present steel is moulded crossover sub and directly contacted with ground, directly contacts with mud, can reduce the anti-corrosion capacity that steel is moulded crossover sub.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of can avoiding to mould crossover sub with the steel that ground directly contacts.
Technical solution of the present utility model is, provides a kind of steel with following structure to mould crossover sub, comprises plastic pipe and metal pipe element; Described plastic pipe is socketed in outside described metal pipe element; Compress by compressing member outside the joint of described plastic pipe and metal pipe element; The joint of described plastic pipe and metal pipe element is provided with back-off structure and seal ring; The outer wall of described metal pipe element is provided with waterproof jacket; The end of described plastic pipe is against on described waterproof jacket; The height of described waterproof jacket is higher than the height of described compressing member; The joint of described plastic pipe and metal pipe element is provided with the two seals circle.
After adopting above structure, steel of the present utility model is moulded crossover sub, compared with prior art, has the following advantages:
The outer wall of moulding the metal pipe element of crossover sub due to steel of the present utility model is provided with waterproof jacket, the end of described plastic pipe is against outside described waterproof jacket, like this, waterproof jacket not only has plastic pipe is carried out spacing function, and can also avoid steel to mould crossover sub directly contacting with ground, directly contact with mud, like this, make anti-corrosion capacity that steel moulds crossover sub more; In addition, the joint of described plastic pipe and metal pipe element is provided with the two seals circle, and like this, the sealing effect between plastic pipe and metal pipe element is better.
As a kind of improvement of the present utility model, the outer wall of described waterproof jacket is provided with a plurality of grooves along the waterproof jacket radial depressions; Described groove is evenly distributed on the outer wall of described waterproof jacket.After adopting this kind structure, described groove can pass through for sewage, avoids hindering sewage flow.
As another kind of improvement the of the present utility model, scribble the clinkery epoxy powder coating with antisepsis on the outer wall of described metal pipe element.After adopting this kind structure, improve the antiseptic power of metal pipe element.
Also have a kind of improvement as of the present utility model, the outer wall of the joint of described metal pipe element is provided with two radial grooves; Be equipped with described seal ring in described two radial grooves.Simple in structure, easy to assembly.
