Abstract
The invention belongs to the technical field of pipeline installation, and particularly relates to a variable-diameter type Huff section sealing gasket. The sealing gasket comprises two arc-shaped sealing strips, wherein the radius of one arc-shaped sealing strip is larger than that of the other arc-shaped sealing strip, and two ends of the two arc-shaped sealing strips are connected through two arch-shaped sealing strips, so that a closed-loop sealing ring is formed. According to the variable-diameter type Huff section sealing gasket, the diameters of the two ends of a Huff section can be designed independently according to the diameter change of pipelines, and accordingly the variable-diameter type Huff section sealing gasket is formed. The sealing gasket can be used for blocking variable-diameter pipelines so that actual working condition demands can be met.
Description
Technical field
The invention belongs to pipe installation technology field, be specifically related to a kind of reducing type sealing gaskets of Hafu joint.
Background technology
Pipeline leakage plugging device is mainly used in the field such as pipe first-aid or pipeline connection, and its structure mainly includes two half shells,

Pipeline leakage plugging device is often isometrical structure, when in the face of the operating mode of some complexity, is difficult to say that pipeline is shut completely.
Such as in the junction of two reducing pipes, traditional isometrical pipeline leakage plugging device just cannot be worked together tight with two pipelines
Coordinate, be therefore badly in need of a kind of novel pipeline leakage plugging device structure to adapt to this duty requirements.
Summary of the invention
It is an object of the invention to provide a kind of reducing type pipeline leakage plugging device that can tapered pipeline be blocked to seal
Pad.
For achieving the above object, the invention provides techniques below scheme: a kind of reducing type sealing gaskets of Hafu joint,
Including two arc sealing strips, wherein the radius of an arc sealing strip is more than the radius of another arc sealing strip；
The two ends of two arc sealing strips are connected by two arch sealing strips respectively, form a closed loop sealing ring.
The both sides of described arc sealing strip and the both sides of arch sealing strip are laid with multiple protuberance.
Described protuberance is semi-cylindrical.
The projection being respectively arranged at two ends with a wedge shape of described arc sealing strip, the inside edge of described projection
Higher than outer ledge.
The inner ring surface of described arc sealing strip is provided with a plurality of arc convex ridge.
Described arch sealing strip is provided with locating convex block.
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 reducing type sealing gaskets of Hafu joint, it is possible to be used for blocking tapered pipeline, to adapt to reality
The duty requirements on border.
Accompanying drawing explanation
Fig. 1 is the installation diagram of the present invention；
Fig. 2 is semicircular housing and sealing gasket assembling stereogram；
Fig. 3 is semicircular housing axonometric chart；
Fig. 4 is the sealing gasket axonometric chart of the present invention.
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 sealing gaskets of Hafu joint, including two semicircular housings 10, two semi-rings
Shape housing 10 engaging constitutes tubular shell, and the diameter of wherein one end of this tubular shell is more than the diameter of the other end,
The junction at two reducing pipes 30 can be sandwiched；The seam crossing of described two halves circular shell 10 with
And it is equipped with sealing gasket 20 between the mouth of pipe at tubular shell two ends and pipeline 30 outer wall.The pipeline leakage plugging device two of the present invention
The diameter of pipeline 30 is changed by the diameter needles of end, carries out individually designed, forms reducing type sealing gaskets of Hafu joint,
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.
Preferably, as it is shown on figure 3, be provided with two arc strip grooves inside the arc-shaped side at semicircular housing 10 two ends
13；The arch limit of semicircular housing 10 both sides is provided with two arcuate strips grooves 14；Described two arcuate strips grooves 14
Sequentially connect with two arc strip grooves 13, form an annular bar groove closed and be used for housing described sealing gasket 20.
Preferably, the arch limit of described semicircular housing 10 both sides is provided with the flange 11 protruded out laterally,
Two halves circular shell 10 utilizes the bolt mounting holes offered on this flange 11 to be connected by bolt 12.
Preferably, described arcuate strips groove 14 is arranged on the end face of described flange 11.
Preferably, as shown in Figure 2,4, described sealing gasket 20 includes two arc sealing strips 21, wherein one
The radius of arc sealing strip 21 is more than the radius of another arc sealing strip 21；The two ends of two arc sealing strips 21
It is connected by two arch sealing strips 22 respectively, forms a closed loop sealing ring.
Preferably, the both sides of described arc sealing strip 21 and the both sides of arch sealing strip 22 are laid with multiple
Protuberance 24, this protuberance 24 and described arc strip groove 13 and the sidewall interference fit of arcuate strips groove 14, make sealing
