Abstract

The utility model discloses a spherical Huff joint. The spherical Huff joint comprises an upper shell and a lower shell. Semispherical protrusions are arranged in the middle of the upper shell and the middle of the lower shell. A spherical cavity is formed in the protrusions. An FEPM layer is arranged on the inner wall of the spherical shell in a vulcanization mode. The spherical Huff joint is simple in structure, convenient to install and use, and suitable for the situation that a portion where leakage occurs is large in structure size and large in occupied space and can not be closed by a common Huff joint.

Description

Spherical pipeline leakage plugging device
Technical field
The utility model relates to a kind of spherical pipeline leakage plugging device.
Background technique
In prior art, the using scope of pipeline leakage plugging device is more and more wider, in the laying and using process of some chemical plant pipelines and gas pipe line, pipeline leakage plugging device is all often used, and the corrosivity in chemical plant is strong, and pipeline leakage plugging device is easily corroded, and at pipe coupling place complicated structure, be not easy leak stopping, cause the phenomenons such as sealing is poor.
Model utility content
The utility model object is to provide a kind of simple in structure, easy to install, and the structure that is applicable to leak is larger, and the common pipeline leakage plugging device that causes greatly of taking up room is difficult to the spherical pipeline leakage plugging device of inclusion situation.
The utility model technical solution problem provides following scheme:
A kind of spherical pipeline leakage plugging device, comprises upper and lower two housings, it is characterized in that: the middle part of described upper and lower two housings has hemispherical projections, and the inside of described projection has spherical hollow space, and on the inwall of described spherical shell, sulfuration has one deck 4 third fluororubber layer.
The side margin of described upper and lower casing is provided with connecting plate, and described connecting plate is provided with lock bolt.
The utility model is provided with hemisphere jut at the intermediate section of upper and lower two housings, in pipeline leakage plugging device, form like this spherical hollow space, can tackle so baroque pipe joint structure, and on the inwall of upper and lower two housings, be attached with 4 third fluororubber layer, prevent that housing is corroded.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
