Abstract
The utility model discloses a Haff joint with a liner. The Haff joint comprises a casing, wherein a spring hole is formed in the inner wall of the casing; a spring is mounted in the spring hole; an arc pressing plate is fixedly connected to the upper end of the spring; the pressing plate can move up and down inside the casing. The Haff joint is simple in structure, high in strength, excellent in pressure resistance, and not easy to fracture.
Description
Technical field
The utility model relates to a kind of pipeline leakage plugging device with inner bag.
Background technique
In prior art, pipeline leakage plugging device in use there will be pipeline leakage plugging device insufficient strength, and the crushing resistance of pipeline leakage plugging device is poor, easily bursting by freezing.
Model utility content
The utility model object is to provide a kind of simple in structure, and intensity is large, and crushing resistance is good, is not easy the pipeline leakage plugging device with inner bag of fracture.
The utility model technical solution problem provides following scheme:
With a pipeline leakage plugging device for inner bag, comprise housing, it is characterized in that: the inwall of described housing is provided with spring eye, in described spring eye, spring is installed, the upper end of described spring is fixedly connected with arc pressuring plate, and described pressing plate can upper and lower activity in housing.
Described pressing plate is provided with multiple relief holes.
The utility model is provided with spring eye on housing, and in spring eye, be provided with spring, on spring, be installed with arc pressuring plate like this, the radius of arc pressuring plate is consistent with tube wall radius, in the installation process of pipeline leakage plugging device, pressing plate is first offset a part of hydraulic pressure under the effect of spring like this, more afterwards hydraulic pressure is delivered on the housing of pipeline leakage plugging device, make pipeline leakage plugging device convenient in installation process, and be not easy fracture.
