Abstract
The utility model discloses a compression-resistant Hafu joint, which comprises an upper semi-housing and a lower semi-housing, wherein the upper semi-housing and the lower semi-housing are cylindrical when being closed; a plurality of ring-shaped grooves are formed in the side walls of the upper semi-housing and the lower semi-housing; semicircular strip-shaped locking hold hoops are arranged in the ring-shaped grooves in the upper semi-housing and the lower semi-housing; the upper semi-housing and the lower semi-housing are locked together by the semicircular strip-shaped locking hold hoops. The compression-resistant Hafu joint has high compressive strength, and is not easy to swell.
Description
Technical field
The utility model relates to a kind of resistance to compression pipeline leakage plugging device.
Background technique
In prior art, pipeline leakage plugging device installing and using the maximum problem running in process is, when pipeline leakage plugging device uses for a long time, because the excessive pipeline leakage plugging device that causes of pressure of pipeline leakage plugging device inside is by spreading, leakage accident occurs.
Model utility content
It is large that the utility model object is to provide a kind of compressive resistance intensity, and pipeline leakage plugging device is difficult for by the resistance to compression pipeline leakage plugging device of spreading.
The utility model technical solution problem provides following scheme:
A kind of resistance to compression pipeline leakage plugging device, comprise upper and lower two halves housing, it is characterized in that: described upper and lower two halves housing closure is cylindric while getting up, the sidewall of described upper and lower two halves housing is provided with multiple tracks annular groove, in the annular groove of described upper and lower two housings, be provided with semicircle Bar lock and hug hoop, described semicircle Bar lock hugs hoop upper and lower two halves housing is locked together.
The forward and backward end of described upper and lower two housings is equipped with sealed port.
The utility model is provided with annular groove on the sidewall at upper and lower two and half housings, and semicircle locking anchor ear is set in annular groove, hold tightly together tightly low upper and lower two housings by multiple annular anchor ears, by the setting of multiple anchor ears, can effectively ensure the intensity of pipeline leakage plugging device like this.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
