Description

Technical Field

[0001] The utility model belongs to the technical field of sealing components, and particularly relates to a sealing component for a steel-lined tetrafluoroethylene pipeline. Background Technique

[0002] A common sealing component for a steel-lined tetrafluoroethylene pipeline is a flange. A flange is a common way to connect pipelines. It usually consists of two parallel flange plates and a sealing gasket in the middle. In a steel-lined tetrafluoroethylene pipeline, the flange is used to connect different parts of the pipeline or connect the pipeline with other equipment or pipeline systems.

[0003] For existing steel-lined tetrafluoroethylene pipelines, there is a lack of protection when not in use. Steel-lined servo pipelines are usually stacked together after being manufactured. When not sold for a long time, the steel-lined servo pipelines are exposed to the air for a long time, which makes it easy for dust and impurities in the air to accumulate on the inner wall of the steel-lined servo pipelines, causing pollution. Since no protective measures can be taken for the steel-lined tetrafluoroethylene pipelines, it is necessary for the staff to clean and repair the steel-lined tetrafluoroethylene pipelines more frequently, resulting in an increase in maintenance costs.

The support plate 24 drives the clamping shell 25 to move to clamp the flange 11, so that the cover shell 21 is in close contact with the flange 11. By rotating the forward and reverse rocking disc rod 27, the clamping shell 25 is driven to seal the steel-lined tetrafluoroethylene pipe 1. This protects the steel-lined tetrafluoroethylene pipe 1 from being contaminated by dust and impurities inside the steel-lined tetrafluoroethylene pipe 1, so that the staff does not need to frequently clean and repair the inside of the steel-lined tetrafluoroethylene pipe 1, reducing the maintenance cost.

[0037] When using this device, place the steel-lined PTFE pipe 1 above the support shell 31. At this time, rotate the turntable 311. The turntable 311 drives the 210 to rotate on the inner wall of the connection shell 39. The worm 310 drives the worm wheel 38 and the threaded rod 33 to rotate on the inner wall of the support shell 31. The threaded rod 33 drives the moving shell 34 to move on the inner wall of the limit shell 32. The moving shell 34 drives the double-threaded rod 35, the knob 36 and the clamping plate 37 to move. Then rotate the knob 36. The knob 36 drives the double-threaded rod 35 to rotate. The double-threaded rod 35 drives the two clamping plates 37 to slide on the inner wall of the moving shell 34, so that the two clamping plates 37 approach each other to clamp and store the steel-lined PTFE pipe 1. By rotating the turntable 311, the clamping plate 37 is driven to adjust the height up and down. By rotating the knob 36, the two clamping plates 37 are driven to move left and right for adjustment, so as to adaptively clamp and store the steel-lined PTFE pipe 1, enabling the clamping plate 37 to flexibly adapt to steel-lined PTFE pipes 1 of different sizes and shapes, achieving precise clamping and ensuring that the pipeline is stably fixed and stored.
