Abstract
The utility model relates to a loose joint connecting type lining polytetrafluoroethylene pipeline, a bend, and a reducing pipe. The loose joint connecting type lining polytetrafluoroethylene pipeline, the bend, and the reducing pipe are characterized in that a first connector and a second connector are respectively connected with a pipeline at a butt joint end position of two pipelines, the outer end faces of the first connector and the second connector are both provided with outer threads, inner threads matched with the outer threads are arranged on an outer sleeve, the first connector and the second connector are fastened through the outer sleeve, a coated pad is arranged on a butt joint face of the first connector and the second connector. The loose joint connecting type lining polytetrafluoroethylene pipeline, the bend, and the reducing pipe have the advantages that due to the facts that the first connector and the second connector are fixedly connected together through the outer sleeve, and a sealing cushion and the coated pad which are coated with polytetrafluoroethylene layers, the anticorrosion effect is good and dismantlement is convenient.
Description
Technical field
The utility model relates to a kind of joint, and concrete is a kind of loose joint jointing type inner liner polytetrafluoroethylene pipeline, elbow and reducer.
Background technique
In technical fields such as oil, chemical industry, anticorrosion most important for pipeline is in the prior art, the joint that exists exists and connects unstable problem, and the pipeline at butt end place causes coming off of anticorrosive coat owing to reasons such as installation, dismountings, the serious working life that has affected pipeline.
Summary of the invention
For overcoming the defective of prior art, the utility model provides a kind of loose joint jointing type inner liner polytetrafluoroethylene pipeline, elbow and reducer that is connected firmly with corrosion-resistant effect that have.The technical solution of the utility model is: a kind of loose joint jointing type inner liner polytetrafluoroethylene pipeline, elbow and reducer, it is characterized in that: the first joint and the second joint have been threaded respectively on the pipeline at place, the butt end of two pipelines, the exterior edge face of described the first joint and the second joint is provided with outside thread, be provided with the internal thread that cooperates with described outside thread on the outer sleeve, described outer sleeve is fastening with the first joint and the second joint, is provided with on the interface of described the first joint and the second joint to coat pad.
The inside of described two pipelines is lined with respectively the first internal lining pipe and the second internal lining pipe, described the first internal lining pipe and the second internal lining pipe all extend radially outwardly at the place, butt end, form respectively the first extension part and the second extension part, be provided with sealing gasket between described the first extension part and the first joint and between the second extension part and the second joint.
The periphery of described the first internal lining pipe, the second internal lining pipe, sealing gasket and/or coating pad scribbles polytetrafluoroethylene floor.
The utility model has the advantages that: be connected firmly between two pipelines, in the port that connects, antiseptic effect is obvious, can adapt to abominable working environment simultaneously, such as environment such as high temperature resistant, anti-strong acid and highly basic.
