Description
Technical field
The present invention relates to a kind of waterproofing devices, and in particular to a kind of pipeline water blocking device.
Background technology
Some pipelines are not allow for water entrance, for protecting the equipment in pipeline.Water inspection is arranged in the prior art in pipeline
Examining system for the water inlet in signal piping, but cannot block in time, and the water continued to flow into can damage the equipment in pipeline.
Invention content
In view of the deficiencies of the prior art, the present invention proposes one kind can block in time when pipeline is intake, effective protection pipeline
The pipeline water blocking device of middle equipment.
The present invention is achieved through the following technical solutions technical goal.
Pipeline water blocking device, including axle housing, end cap；The axle housing is vertically arranged, and is equipped with big end in upper ladder hole, ladder hole
Lower part be inlet hole；The end cap is threadedly coupled with axle housing ladder hole top, end-cover axle shoulder end face and axle housing upper surface it
Between be equipped with sealing ring I；The end cap is equipped with the outlet opening opposite with axle housing ladder hole；It is theed improvement is that：The axis
Floating sealing structure is equipped in shell ladder hole；The floating sealing structure includes inner sleeve, mandril, sealing ring II；The end cap
Outlet opening lower part is equipped with big end sealing cone directed downwardly；The inner sleeve is the sleeve-shaped member of upper end closed, is supported on axle housing ladder
On the inlet hole upper surface of through-hole, coordinate with ladder hole, inner sleeve endoporus is downward blind hole, if inner sleeve lower face is equipped with trunk diameter
To the slot of perforation；The mandril is vertically arranged, and is fixedly connected on inner sleeve upper surface, and mandril outer wall is equipped with annular groove, is equipped in annular groove close
Seal II；The inner sleeve moves up, and mandril stretches into end cap outlet opening, and sealing ring II is in close contact with the end cap seal conical surface,
Form sealing structure.
The floating sealing structure further includes nut；The nut thread is connected on mandril, is resisted against inner sleeve upper surface.
Compared with prior art, the present invention having the positive effect that：
1. the present invention is in use, when there is water to enter pipeline, water enters from the inlet hole of axle housing ladder hole, pushes inner sleeve
It moves up, mandril stretches into end cap outlet opening, and sealing ring II is in close contact with the end cap seal conical surface, forms sealing structure, rises
To Truncation, equipment in effective protection pipeline.
2. being equipped with nut in floating sealing structure, and bar is pressed closer, can prevent mandril from loosening.
