Description
Technical field
A kind of sewage transport pipe leak source of the present invention checks plugging device, is related to one kind in Chemical Manufacture, to sewage transport
Pipe carries out the device blocked when leak source detection to sewage transport pipe, belongs to field of chemical equipment.In particular to one kind passes through
The cooperation of multiple clamping limbs and fixed ring, the device that sewage transport tube end is blocked.
Background technique
Currently, sewage pipe can be connected to treatment tank in Chemical Manufacture and handled, then again by treated
Waste liquid is discharged, and when by sewage transport to treatment tank, tube body is mostly used to be transmitted, due to pipe fitting mostly welding
At, therefore in use, it often will appear leakage, cause pollution to leak, influence environment, it is therefore desirable to the leakage to sewage pipe
Point is checked, when being checked, biggish leak source can be found out by naked eyes, but lesser or subtle need tube body
It blocks, inwardly injects gas or liquid suddenly, the infiltration situation by observing lateral wall carries out finding leak source, but is being blocked
When, since the nozzle of sewage pipe is there are foreign matter accumulation, simple sealing will appear leakage, influence finding leak source, existing to incite somebody to action
Foreign matter is first cleared up and is blocked again, time-consuming and laborious, inefficiency, while the existing point that blocks is mainly by the folder of outer wall
It holds and is fixed, structure occupied space is big, and it is not compact, it is inconvenient using carrying, and plugging structure is reserved gas injection channel, is influenced
Leak source detection.
Summary of the invention
In order to improve above situation, it is a kind of by more that a kind of sewage transport pipe leak source of the present invention checks that plugging device provides
The cooperation of a clamping limb and fixed ring, the device that sewage transport tube end is blocked.Without carrying out foreign matter cleaning, Neng Gouyou
Effect is improved to sewage pipe plug at end part efficiency.
