Abstract

The invention belongs to the technical field of pipe installation, and particularly relates to a variable-diameter type Huff section shell convenient to hoist. The variable-diameter type Huff section shell comprises two semi-ring casings, wherein the two semi-ring casings are clamped to constitute a pipe-like casing, and the diameter of one end of the pipe-like casing is larger than that of the other end, so that the pipe-like casing can be clamped at the joint of two pipes with different diameters; a through hole is formed in one semi-ring casing, a plug is arranged at the through hole and connected with the through hole through threads, and a lifting ring is arranged outside the plug. The diameters of two ends of a Huff section are independently designed according to change of the diameters of the pipes, and the variable-diameter type Huff section shell convenient to hoist is formed and can be used for blocking variable-diameter pipes so as to meet requirements of actual working conditions.

Described semicircular housing is groove-like structure, and when two halves circular shell engages, tubular shell two ends are receipts Mouth shape, radially outward arches upward along pipeline in tubular shell stage casing.
Two arc strip grooves it are provided with inside the arc-shaped side at semicircular housing two ends;The arch of semicircular housing both sides Limit is provided with two arcuate strips grooves;Described two arcuate strips grooves and two arc strip grooves sequentially connect, and form an envelope The annular bar groove closed is for housing described sealing gasket.
The arch limit of described semicircular housing both sides is provided with the flange protruded out laterally, two halves circular shell The bolt mounting holes offered on this flange is utilized to be bolted.
Described arcuate strips groove is arranged on the end face of described flange.
The bottom land of described arcuate strips groove is provided with locating slot.
The method have technical effect that: the diameter of pipeline is changed by the diameter needles at the pipeline leakage plugging device two ends of the present invention, Carry out individually designed, form the reducing type pipeline leakage plugging device housing being easy to lifting, it is possible to be used for blocking tapered pipeline, To adapt to the duty requirements of reality.
Accompanying drawing explanation
Fig. 1 is the installation diagram of the present invention;
Fig. 2 is semicircular housing and the sealing gasket assembling stereogram of the present invention;
Fig. 3 is the semicircular housing axonometric chart of the present invention;
Fig. 4 is sealing gasket axonometric chart.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In describing the invention, it should be noted that term " interior ", " outward " etc. instruction orientation or position Put relation for based on orientation shown in the drawings or position relationship (i.e. the side with tube fit is inner side, away from The side of pipeline is outside), it is for only for ease of the description present invention and simplifies description rather than instruction or hint The device of indication or element must have particular orientation structure and operation, therefore it is not intended that to the present invention's Limit.
As it is shown in figure 1, a kind of reducing type pipeline leakage plugging device housing being easy to lifting, including two semicircular housings 10, Two halves circular shell 10 engaging constitutes tubular shell, and the diameter of wherein one end of this tubular shell is more than the other end Diameter so that it is the junction at two reducing pipes 30 can be sandwiched;Described two halves circular shell 10 It is equipped with sealing gasket 20 between seam crossing and the mouth of pipe at tubular shell two ends and pipeline 30 outer wall;One of them Semicircular housing is provided with a through hole, and described through hole is provided with a plug, and described plug and through hole pass through screw thread Connect, outside described plug, be provided with suspension ring, in order to lifting transfer.The pipeline leakage plugging device two ends of the present invention straight Footpath changes for the diameter of pipeline 30, carries out individually designed, forms the reducing type pipeline leakage plugging device housing being easy to lifting, Can be used in blocking tapered pipeline 30, to adapt to the duty requirements of reality.
Preferably, as shown in Figure 2,3, described semicircular housing 10 is groove-like structure, when two semicircular shells When body 10 engages, tubular shell two ends are closing in shape, radially outward arch upward along pipeline 30 in tubular shell stage casing.
