Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of sealing cover suitable for different tube diameters.
Background technique
Be segmented sand washing or when open work, some pipelines be it is open, dust or grit can enter channel interior, right
Pipeline inner wall damages, and in order to avoid dust or grit can enter channel interior, needs to close pipeline opening.This
Outside, in cabin air seal test, it is also desirable to carry out temporary plugging to open pipeline.
Therefore, it is necessary to design a kind of sealing cover suitable for different tube diameters, pipeline can be entered to avoid dust or grit
Inside, while meeting the needs of cabin air seal test carries out temporary plugging to open pipeline.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies of the prior art and provide a kind of sealings suitable for different tube diameters
Lid can enter channel interior to avoid dust or grit, while meet cabin air seal test and temporarily be sealed to open pipeline
Stifled demand.
In order to achieve the above object, the utility model is a kind of sealing cover suitable for different tube diameters, including thread,
Fastening nut, end cap, gasket seal, anchoring pawl, tension spring, it is characterised in that: thread passes through the center of end cap, fastening nut
Positioned at the top of end cap, using being threadedly coupled between fastening nut and thread, the lower end of thread is fixed with fixed block,
The both ends of fixed block are connect with the end of a connecting rod respectively, and the other end of connecting rod is connect with anchoring pawl, two anchorings
It is connected between pawl using tension spring, the bottom of end cap is pasted with gasket seal.
The end cap, gasket seal are covered on the open-mouth of pipeline, and the inner surface of pipeline is withstood on the surface for being anchored pawl.
The pipeline is arranged in the bulkhead plate between pump gas cabin and adjacent non-pump gas cabin.
Shaft connection is all made of between the fixed block and connecting rod, between the connecting rod and anchoring pawl.
Compared with the prior art, the utility model designs sealing cover structures, can enter pipe to avoid dust or grit
Inside road, while meeting the needs of cabin air seal test carries out temporary plugging to open pipeline.The utility model can be in certain model
It encloses interior adjusting and blocks internal diameter, flexibility ratio is high, fixes or is welded and fixed without adhesive tape, and it is easy for installation, pipeline and week are not destroyed
Closed structure coating, reusable, save the cost.The utility model is suitable for Ship Building and Repairing and other needs temporarily to seal pipeline
Stifled industry.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the usage state diagram of the utility model.
Fig. 3 is sealing schematic diagram of the utility model for small diameter tube pipeline.
Fig. 4 is sealing schematic diagram of the utility model for Large Diameter Pipeline pipeline.
Specific embodiment
The utility model is described further now in conjunction with attached drawing.
Referring to Fig. 1, the utility model is a kind of sealing cover suitable for different tube diameters, including thread, fastening nut,
End cap, gasket seal, anchoring pawl, tension spring, thread 1 pass through the center of end cap 3, and fastening nut 2 is located at the top of end cap 3,
Using being threadedly coupled between fastening nut 2 and thread 1, the lower end of thread 1 is fixed with fixed block, the both ends of fixed block
It is connect respectively with the end of a connecting rod, is all made of shaft company between fixed block and connecting rod, between connecting rod and anchoring pawl
It connects.The other end of connecting rod is connect with anchoring pawl 5, is connected between two anchoring pawls 5 using tension spring 6, and the bottom of end cap 3 attaches
There is gasket seal 4.
Referring to fig. 2,3, pipeline 7 is arranged in the bulkhead plate between pump gas cabin and adjacent non-pump gas cabin.This is practical new
Type selects temporary sealing lid at work, according to pipeline diameter, and end cap 3, gasket seal 4 are covered on the open-mouth of pipeline 7, rotates
Fastening nut 2 pulls out thread 2, and anchoring pawl 5 is to two Slideslips, until pipeline 7 is withstood on the surface of anchoring pawl 5
Inner surface.Then fastening nut 2 is tightened, sealing cover and tube wall are locked.It is when needing to dismantle sealing cover, fastening nut 2 is anti-
To rotation, under the action of tension spring 6, anchoring pawl 5 resets, and sealing cover unlocks with tube wall, can remove sealing cover.
Referring to fig. 4, when needing to seal the pipeline 7 of Large Diameter Pipeline, fastening nut 2 only need to be further rotated, increases anchoring pawl 5
To the distance of two Slideslips.
The utility model devises sealing cover structure, can enter channel interior to avoid dust or grit, meet simultaneously
Cabin air seal test carries out the demand of temporary plugging to open pipeline.The utility model can be adjusted in closure in a certain range
Diameter, flexibility ratio is high, fixes or is welded and fixed without adhesive tape, easy for installation, does not destroy pipeline and surrounding structure coating, can weigh
It is multiple to utilize, save the cost.The utility model is suitable for Ship Building and Repairing and other needs to pipeline temporary plugging industry.
