Improved backflow prevention pipeline

Abstract

The invention discloses an improved backflow prevention pipeline which comprises an inner pipe and an outer pipe outside the inner pipe. A vacuum gap exists between the inner pipe and the outer pipe,and reinforcing ribs are arranged in the gap, are in a continuous S shape and are provided with a plurality of bent parts. Every two adjacent bent parts are fixed to the inner pipe and the outer pipeseparately. The inlet end of the inner pipe is provided with a water baffle, one end of the water baffle is fixed to the upper portion of the inlet end through hinges, and the other end of the water baffle forms a free end. A lap joint block is arranged at the position, corresponding to the water baffle, of the lower portion of the inlet end. A magnet is arranged inside the lap joint block. The free end of the water baffle is provided with an iron sheet. The side, facing the inlet end, of the lap joint block is arc, the side, back to the inlet end, of the lap joint block is provided with an auxiliary block, and the free end of the water baffle is provided with a notch matched with the auxiliary block. The improved backflow prevention pipeline provided by the invention is durable, good in backflow prevention effect and worth popularizing.

Description

technical field [0001] The invention relates to an improved anti-backflow pipeline, which belongs to the technical field of pipelines. Background technique [0002] Pipelines have an extremely wide range of uses in modern industry, and fluid transportation is realized through various pipeline connections. However, when the existing pipeline is in use, it is impossible to effectively avoid the phenomenon of fluid backflow, which causes fluid disturbance in the pipeline and affects the stability of the entire pipeline, which is not conducive to the smooth flow of fluid and the long-term use of the pipeline. In addition, the existing pipes are usually thickened to extend the service life, which not only increases the material but also weighs heavily, which is not conducive to handling, assembly, and use, and greatly increases manpower and material resources, so further research is needed. Contents of the invention [0003] In order to overcome the deficiencies in the prior a...

However, when the existing pipeline is in use, it is impossible to effectively avoid the phenomenon of fluid backflow, which causes the fluid disorder in the pipeline to affect the stability of the entire pipeline, which is not conducive to the smooth flow of fluid and the long-term use of the pipeline.

In addition, existing pipelines are usually thickened to prolong their service life, which not only increases the material but also weighs heavily, which is not conducive to handling, assembly, and use, and greatly increases manpower and material resources, so further research is needed
