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, and the annular bar groove for forming a closing is used for House the sealing gasket.

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 it is individually designed, formation be easy to lift reducing type pipeline leakage plugging device housing, can be used in block tapered pipeline, to adapt to reality The duty requirements on border.

Specific embodiment

This utility model is described in detail below in conjunction with accompanying drawing.

In description of the present utility model, it should be noted that the orientation of the instruction such as term " interior ", " outward " or position relationship It is (to be inner side i.e. with the side of tube fit, be outer away from the side of pipeline based on orientation shown in the drawings or position relationship Side), it is for only for ease of description this utility model and simplifies description, rather than indicates or imply that the device or element of indication are necessary Construct with particular orientation and operate, therefore it is not intended that to restriction of the present utility model.

As shown in figure 1, a kind of reducing type pipeline leakage plugging device housing for being easy to lift, including two semicircular housings 10, two semi-rings The engaging of shape housing 10 constitutes tubular shell, the diameter with diameter greater than the other end of wherein one end of the tubular shell so as to can Sandwich in the junction of two reducing pipes 30；The seam crossing of the two halves circular shell 10 and the mouth of pipe at tubular shell two ends Sealing gasket 20 is equipped between 30 outer wall of pipeline；One of semicircular housing is provided with a through hole, and the through hole is provided with One plug, the plug are threaded connection with through hole, are provided with suspension ring outside the plug, in order to lift by crane transfer.This reality With diameter change of the diameter needles at new pipeline leakage plugging device two ends to pipeline 30, carry out individually designed, the reducing for lifting is easy in formation Formula pipeline leakage plugging device housing, can be used in blocking tapered pipeline 30, to adapt to actual duty requirements.

Preferably, as shown in Figure 2,3, the semicircular housing 10 is groove-like structure, when two halves circular shell 10 engages, Tubular shell two ends are in closing in shape, and tubular shell stage casing is radially outward arched upward along pipeline 30.

Preferably, as shown in figure 3, being provided with two arc bar grooves 13 on the inside of the arc-shaped side at 10 two ends of semicircular housing；Semi-ring The arch side of 10 both sides of shape housing is provided with two arch bar grooves 14；The two arches bar groove 14 and two arc bar grooves 13 sequentially connect Logical, the annular bar groove for forming a closing is used for housing the sealing gasket 20.

Preferably, the arch side of 10 both sides of semicircular housing is provided with the flange 11 for protruding out laterally, two semi-rings Shape housing 10 is connected by bolt 12 using the bolt mounting holes opened up on the flange 11.
