The purpose of this utility model is to provide a kind of reducing type pipeline leakage plugging device housing that can be blocked to tapered pipeline.
For achieving the above object, this utility model provides technical scheme below:A kind of reducing type pipeline leakage plugging device housing, including
Two semicircular housings, two halves circular shell engaging constitute tubular shell, wherein one end of the tubular shell with diameter greater than another
The diameter of one end so as to can sandwich in the junction of two reducing pipes.
The semicircular housing is groove-like structure, and when two halves circular shell engages, tubular shell two ends are in closing in shape, are managed
Radially outward arch upward along pipeline in shape housing stage casing.
Two arc bar grooves are provided with the inside of the arc-shaped side at semicircular housing two ends;Set on the arch side of semicircular housing both sides
There are two arch bar grooves;The two arches bar groove is sequentially connected with two arc bar grooves.
The arch side of the semicircular housing both sides is provided with the flange for protruding out laterally, and two halves circular shell is utilized should
The bolt mounting holes opened up on flange are bolted.
The arch bar groove is arranged on the end face of the flange.
The bottom land of the arch bar groove is provided with locating slot.
It is of the present utility model to have technical effect that:The diameter needles at pipeline leakage plugging device two ends of the present utility model become to the diameter of pipeline
Change, carry out individually designed, formation reducing type pipeline leakage plugging device housing, can be used in blocking tapered pipeline, needed with adapting to actual operating mode
Ask.
